Children At Play

Synopsis: In a small gaited commune-like town that is somewhat technophobic in it's culture and has what seem to be some strange sexual values and lacking sex education for young children, a small family that includes 5 children from 2 separate mothers begins bumbling around with discovering sex on their own after one of the girls starts into a case of extreme precocious puberty.

Part 1: Period

Timothy's parents were almost constantly busy. They lived in a large household together with their aunt. Both his parents and his aunt were almost constantly out of the house, and when they were in the house they were almost always too tired to spend much time with their kids and were hiding back in their rooms near the back of the house.

All of this wound up meaning Timothy, as the oldest, was left in charge. He'd wound up having this role since he was eight years old, before he was properly old enough to babysit. After he turned ten, his parents wound up leaving him alone with his younger cousins and siblings a lot more often. Now, at eleven, it seemed like he was more a parent to them than his own parents were.

This was why they had even grown used to running to him whenever they had a problem. As such, it was no surprise when, one morning, his little sister Katie was at his bed-side nudging his arm.

"Tim!" She said, prodding him. "Timmy!"

"Whad is it!" He groaned and rolled over to squint at her as he somewhat resented the fact he was being woken up.

"I'm bleeding!" She said. This got his attention, and he was soon awake an a lot more alert. "Where are you bleeding?" he asked.

"I... I..." she stammered, her voice quivered and Timothy could see the tears threatening to overflow from the little girl. She was only seven years old, so she still cried all the time, but this time she wasn't crying anywhere near as much as he'd expected. She seemed absolutely terrified though.

Without managing to get the words out, the little girl started pulling up her night gown to show him. Timothy had been just thinking maybe it was on her leg or something, but once she'd gotten her night gown above her waist he was immediately able to see the problem was a lot worse than he had feared. Her underwear were stained completely red.

Timothy got scared when he saw that, and despite her being a girl, he reached up and grabbed the waist of her underwear before she could even make a move and pulled them down to her mid-thighs. He had seen girl's privates plenty of times. Him and Sam, as well as their two female cousins, have even played naked games showing each other their privates a lot while their parents were out, and even not counting that, he has also helped their youngest cousin Milly on the toilet. He still does on occasion, even though the kid is five years old and fully potty trained now. For these reasons, he had zero hesitation in stripping his little sister of her panties if there was a medical need.

He could see the smears of blood on Katie's privates, but he could not find any clear signs of injury in regards to where all this blood might have come from. He was fully awake from the adrenaline now as he slipped out of bed and sat on the floor to get a better view of his sister's groin.

"Open your legs a bit more," he told her, which she obeyed without a word. She was whimpering constantly in her obvious fear of what was going on, but she didn't say a word.

Timothy reached up and used his thumbs to pull Katie's slit open. They were a bunch of kids who had been left to their own devices rather frequently, so he had also done this with his sister and cousins before, although that was more out of curiosity to see what the inside of a girl's privates looked like rather than anything to do with what was needed to do in the bathroom.

This is when he saw it. The inside of his sister's privates had something gross that looked like an inner set of lips inside, and there was a hole in the middle. They had once thought that was the hole the pee came out of, but when they tried holding it open while one of the girls was peeing once it came out of a spot a little higher than that. So, he still didn't know why girls had another hole like this that wasn't for their pee. But right now, that hole had blood trickling out of it. This had to mean she had some kind of injury inside of there.

"Do you see it?" Katie asked.

"Yeah, uhh... sort of," Timothy said. He had seen all he could, and he knew this was outside his ability to address. "I'm gonna go get mom and dad!" He said, standing up and running out of the room, not bothering to do anything to fix the state Katie was in. He saw their 8 year old cousin Kristin in the doorway on his way out, clearly worried about Katie as well, and then Millie was a bit behind her in the hall. That would be all three of the girls.

"Timmy, wait!" Katie yelled behind him and scrambled after, falling behind quickly as she had to contend with her panties that were down around her thighs.

He ran into his dad's room, and saw Aunt Angila sleeping next to him. His aunt and his mom both took turns sleeping in dad's room, and it seemed like it was Aunt Angi's turn today.

He ran up to his aunt and immediately started nudging her. "Aunt Angi! Aunt Angi!" He yelled.

"Whh... whaaah?" His aunt groaned awake.

"Katie's bleeding!" He told her. After this, he explained how she was bleeding from inside her privates. However, after he had explained everything, her reaction was nothing at all like what he'd expected.

"Oh, is that what's got you so riled up? That must have been a surprise," she said.

"What's going on?" His dad said as he was woken up by the commotion.

"It's alright, Katie just started her first period and it's got Timmy all upset," she said.

"Oh... oh, wait. Katie? She's seven! Isn't that way too early?" He said.

"Not really," his aunt said. "Me and Debbie both had ours around Kristen's age. Katie is just a little bit early. I'll take care of this. I should probably teach Kristen what to do while I'm at it too," she said as she slipped out of bed.

"What's going on?" Timothy asked.

"It's alright," his aunt said. "It's nothing that boys have to worry about. Katie will be fine though. I'll just take care of this."

And with that, she gathered up Katie, along with his cousins Kristen and Milly, and brought them all to his dad's master bathroom, stopping only to ask Timothy to get Katie a fresh pair of underwear before she shut him out.

After that, his dad gave him a little bit of a talk to settle him down, telling him that this was something that happened to all girls. It was called their period, and Katie would have this happen to her once a month from now on, although it may be a little irregular at the start.

He also said he'd be calling into the school to give Katie the day off, and he'd also get to have a day off so he could take care of her, although apparently they'd be telling the school he was sick too, as was somewhat common for them in cases like this.

His parents didn't tell him much more than that, but as soon as his little brother and cousins were off to school and his parents were off to work, he immediately started asking Katie what aunt Angi had told her to do with her bleeding period stuff.

"She put a weird plastic thing up inside my privates, and then it spat out a sponge-like thing inside me to catch the blood," Katie said in a rather embarrassed tone like she'd rather not be talking about this.

"Can I see?" Timothy asked almost immediately. Without even a word or attempt at argument, Katie simply pulled up the hem of her night gown right there in the middle of the living room and turned toward her big brother. Exploring each other's privates was nothing unusual for them while their parents were out and he was left together with them, so she showed no hesitation at all.

He reached up and pulled down her underwear, which were still clean. This time though, he saw a string dangling from her privates.

"There's a string," he commented.

Katie was silent for a little bit before she started talking in a somewhat hesitant voice. "Y... yeah. It's supposed to be to pull the sponge out when it's time to change it," she said.

"Hmm..." Timothy hummed as he pulled Katie's underwear back up and made her decent. "Well, maybe you can show me when you use the bathroom next time!" he said.

"Yeah," Katie agreed. "Umm... can I make your wee-wee spit again too?"

"Uhh... sure, how about we do that now?" Timothy agreed.

"Ok!" Katie replied and then started following her brother as they both walked quickly to the bathroom.

Both children started stripping off all of their clothes as soon as they reached the bathroom. They had discovered this was the best way to do this, ever since the first time when Kristen and Millie had been playing with Timothy's penis one day and it had started squirting his white stuff all over little Millie's then four year old face.

He had known his penis could make this slimy stuff that wasn't pee come out of it. He had never told his parents about his wet dreams, he had been too embarrassed when he'd thought he'd wet the bed. He still had no idea what this slimy stuff was that came out of his penis, but he was glad that it at least didn't get outside his underwear and get his sheets all wet like pee would have.

That first time his penis started spitting all over Millie was a surprise to all of them. Timothy was shocked that he had no control to make it stop, it just started after it had felt good from them rubbing it and then it just kept going until it was finished.

The girls had thought he peed on Millie, and they were both really upset. It had taken him a while to explain that it wasn't pee. It helped that Kristen was able to quite clearly see the white stuff his penis had just spat all over her baby sister's face, and she was able to calm the girl down, but there were a lot of questions and it was really noisy. It made him glad their parents were still all at work.

At the end of it all, they wound up telling Katie about it and then Kristen and Katie took a huge interest in trying to get a repeat performance, and eventually Millie worked up enough courage to try it again as well.

Ever since then, the girls seemed to really enjoy playing with his penis. Timothy liked it too, he liked it when the girls played these touching games with him, and he had also discovered something else since they'd started this. Ever since the girls started playing with his penis and making it spit out the white stuff during the day, he stopped having the accidents during the night.

Katie laid down on the floor, as was her routine. Timothy crouched down over her in a frog-leg position, and Katie reached forward happily to grab his penis. She pulled back his foreskin, revealing the pink-red tender skin underneath. It was already a little bit slimy.

If the white stuff was like 'spit' that came out of the penis, then this little bit of sliminess was like drool. His penis tended to drool a lot when he started even thinking about playing these touching games with the girls. It drooled a lot more when he thought about touching the girls' privates than when he thought about them touching him for some reason, and he was often able to shoot the white stuff a lot faster when he rubbed his penis directly against their privates.

He wondered if maybe he wouldn't be able to do that this time because of the tampon thing she had inside her privates where she was bleeding from, but soon Katie wound up answering his question without a word as she started pushing him back a little bit. He knew exactly what she wanted to do. He lowered his hips, and Katie pointed his stiff penis straight down and started grinding the slick tip of his penis against the little nub at the top of her slit. This was a favorite of all three girls since he'd started rubbing his penis on their slits. The said it felt best when he rubbed it on that nub at the top.

The two naked children didn't say a word as the seven year old girl happily rubbed the eleven year old boy's penis against her nub. The little girl had said she wanted to make his penis spit, but Timothy had sometimes wondered if the girls really asked him to do this more because they liked the feeling of his penis rubbing against those little nubs.

Katie had a zoned out expression as she kept rubbing it on her nub, pressing harder and getting faster and more erratic. It didn't take long with this before this got Timothy stimulated enough to shoot the white stuff.

"It's about to come out!" He warned her. This made Katie slow down her grinding and she pressed the tip of his penis directly against her nub so his penis would spit the white stuff directly onto that spot. He felt the pulse in his groin, and the creamy white fluid shot out directly onto his little sister's privates. It splattered up onto her pelvis and also running down her crack or the sides of her vulva, finally making a small puddle on the floor, but a healthy amount of it was completely coating Katie's privates.

As soon as Timothy was done shooting his stuff, Katie immediately let go of his penis and grabbed her privates with both hands and started rubbing hard. This was another thing the girls liked doing. When all three of them were together, the other two would often scoop up some of the white stuff he'd shot on the first girl and all three would use it to rub on their privates to make it slippery so they could feel good rubbing themselves.

Sometimes Timothy would help them out with this since it would mean he got to touch their privates a lot, but he didn't like getting his hands all slimy with that stuff that came out of his penis. And besides that, this time he also had to think about her bleeding from earlier. He didn't think he should mess with her privates too much today.

So, he just got dressed while his sister was rubbing herself. He decided to just put his pajamas back on and wear them the rest of the day since they were just going to stay home all day anyway. "Umm... do you need help cleaning yourself up?" he asked her once he was completely decent.

"Ugh! No," she grunted between her aggressive rubbing.

"Umm... Ok, I'm just going to go watch some TV," he said and then left her like that, rubbing her penis-spit covered privates on the bathroom floor. He closed the door on his way out. He knew the two of them were the only ones in the house, but this kind of paranoia was a part of how they kept from being discovered doing this by their parents for so long.

Part 2: More periods?

For the rest of the day, Timothy and Katie enjoyed their day off from school. Katie did show him how her tampons worked. Just as they'd agreed, she'd invited him to watch her pee in the bathroom, and then she asked him to pull out the tampon. In fact, she seemed a little unsure about doing it herself and actually wanted him to help her with it. After that, he found the box aunt Angi had put in the cabinate under the sink of their bathroom for her and got another tampon out of it.

She was asking him for help, but he wasn't the one who was around for aunt Angi's instructions, so he had to have her tell him what he was supposed to do. He had to pull open the lips of Katie's vulva in order to see the hole where the blood was coming out, and then he had to push the weird little plastic thing up inside her and push this plunger that made the sponge thing come out inside her.

He couldn't help thinking though that the little plastic thing looked a little like a penis. It made him wonder if a boy's penis could also go inside a girl's privates. He couldn't try it with Katie though since she was bleeding from that hole and had the tampon up inside of her.

After that, they hadn't really done much more playing with their privates together. Katie did ask him to help her with the tampons every time she went to the bathroom throughout the day, so he actually did wind up touching her privates a fair amount. She seemed to be bleeding a whole lot less now too, but she still wanted to have the tampon changed every single time she went to the bathroom and he was supposed to be the one to help her every time.

He got to play with her privates whenever he did that, and a couple times he touched them well in excess of what he needed to put the tampon inside her without a single complaint from Katie about how he was poking, prodding, and playing with her vulva. It was nothing new for them, after all. But, he never took out his penis and made it spit on her privates again for the rest of the day.

He was still wondering about maybe sticking his penis inside her privates like he did with the tampons, but he couldn't for the same two reasons every time.

Maybe he would try it with Millie when she got home from kindergarten. His dad had told the school she should go home with the walking group after her class was over. The kindergarten got out around 11:00, but usually Millie was put in the after-school daycare program after that until he walked over from the middle school to pick her up. But the teacher would be bringing her home today.

This routine continued with them mainly just watching TV or playing video games, interrupted occasionally by Katie needing the bathroom and whining to her big brother to help her. He felt her "bathroom" trips were way too frequent, and she'd only squeeze out a small trickle of pee after a lot of effort. He understood this was just an excuse to have him touching her privates again, but he never called her on it. In fact, he encouraged it. It got boring just watching TV or playing video games, and their games where they touched each other's privates were a fun distraction.

Timothy sometimes wished they had a computer or a smart phone in the house so they could get on the internet like they saw on TV sometimes, but his parents told him that people didn't have computers or anything that could get on the internet in this community they were living in. It was true, none of his friends had computers either.

This continued until a little past 11 when they heard a crowd of little kid voices coming up to their front door, followed by a knock. Timothy went to get it, he knew exactly what this was. Sure enough, when he opened it, he saw one of the teachers for the Kindergarten surrounded by a bunch of little kids.

"Timothy! Your father called and said you would be home today. I'm here to drop Millie off!" The teacher said, at which point their little five year old cousin ran right in the house.

"Thanks Ms. Hollands," Timothy said to the woman, who pleasantly smiled back at him.

"Well, I won't take up too much of your time. Get back to bed and get plenty of rest now, I hope you feel better and can go back to school soon," the teacher said, and then started herding the small crowd of children off in the opposite direction.

Timothy made a little bit of a difficult face when he heard what Ms. Hollands had said. He wasn't the one who was sick, it was his little sister. But, if he said that, then people would realize that he stayed home from school without being sick, and he would probably get in some trouble for that.

He approached his little cousin as she was finishing up taking her shoes and socks off and storing them in the shoe closet, he felt really eager to try the new thing he'd thought of while playing with Katie today.

"Hey, Millie! I've got a new game I'd like to try in the bathroom," he told her.

"Ok!" The little girl said. She immediately understood that when Timothy said 'in the bathroom,' that what he meant was he wanted to touch her private parts, but that didn't bother her. This was just how her older siblings played, and she was really happy she got to participate in these games and got to be with Kristen, Katie, and Timothy when they were touching her privates. This fact alone made it so she was always really excited to have her privates touched by Timothy.

She got up, teetering to her feet, and then grabbed Timothy by the hand. "Let's go!" She said, filled with enthusiasm that her older cousin had said he wanted to play with her the very second she walked in the door.

She tossed her back-pack to the side as soon as they got into the bathroom and then started hiking up her short school play-dress and pushed her underwear down to the floor and stepped out of of them, and then held her dress up in anticipation as she bared her five year old private parts to her much older cousin, eagerly anticipating him touching and playing with them.

Timothy's heart started beating a little faster when he saw her doing that before he'd even closed the door. His younger cousin hadn't learned any modesty, and this was made worse by the fact he'd taught her to let him play with her private parts so readily.

"Hey, what are you doing?" Katie's curious voice asked from the hallway as she peeked in after them.

"Umm... I was going to try out a new idea I had for a game with our privates," he said to his sister. "Umm... you you wanna watch?" He asked.

Katie just nodded and then stepped in and closed the door behind her. Timothy breathed a little easier when he saw the bathroom door closed, and he started pulling down his own pants and underwear.

He wondered about removing his shirt as well since he was planning to most likely make his penis spit the white stuff again. At the same time, he looked up and pondered Millie's play dress with the same thoughts in mind. His plan was to stick it inside of Millie's privates though. If he did that, it should make it so all his white stuff goes up inside her bladder, or, no, not her bladder. He's going to try to put it up inside the other hole that was where her period would come out of when she got older like Katie.

"Lay down on the floor," he told his little cousin. She followed his instructions immediately and without question, plopping straight down on the floor and then sticking her legs out. All the while, she still held the hem of her dress up as she had a huge anticipatory grin plastered on her face as she looked up at him.

He got down between her legs as soon as she was in position and used his fingers to pull open her vulva so he could find the same hole as Katie had, the spot where on Katie he had just been pushing the plastic things for the tampons inside of his little sister over and over again this morning.

He found the right spot quickly enough, and then immediately started frog-walking forward to get his penis into position.

The smile faded from Millie's face for a second after she saw this. "Are you going to make your wee-wee spit on me?" she asked.

"Umm... uhh... no," Timothy told her. "Well, I mean, I want to try putting my... my pee-pee inside of your pee-pee. You know, the spot where aunt Angie showed you Katie was bleeding from today?"

"Oh..." the little girl said and thought back to this morning when aunt Angie showed them how she stuck the white plastic thing up inside of Katie's girl pee-pee in order to make the bleeding stop.

Timothy's boy pee-pee was around the same size the plastic thing, so she really didn't see why it shouldn't be able to go inside her if she already saw that thing going inside of Katie. In fact, she'd been thinking about that and things going up inside her own private parts all day after seeing that, so hearing Timothy talk about putting his boy privates inside her girl privates was an idea she found very interesting.

She readily spread her legs as Timothy got into position, his legs over hers and his butt right between her legs so that his penis could touch her private parts. He was still holding the lips of her vulva open with both hands, so he started jabbing at her girl parts with his penis, without using his hands to guide it at all.

This was Timothy's first time ever trying to do this, but he'd stuck the white plastic thing for the tampons inside Katie about five times just this morning, so he was able to figure it out quickly after he had his penis close to the right position. He re-positioned his hands so that he was spreading Millie's five year old vulva with only the thumb and index finger of one hand, and then used the other hand to now guide his little stick into position.

Fortunately for the little girl, puberty had not caused Timothy's privates to start seriously growing yet. His penis was only about three and a half inches, and only a little thicker than the tampon applicator tubes.

Due to his practice with the tampons, he had no trouble at all finding the spot where his penis could go inside of his little cousin. He could hear his heart-beat pounding in his head as he nuzzled the head of his penis into her privates, and he felt the velvity muscular walls of the little kindergartener's insides pushing back at him.

He'd rubbed on this area before when they played their privates games, but he never tried actually pushing in here. The girls all seemed to like him rubbing it on the nub at the top anyway. But now, after seeing how those tampon things went inside Katie, he'd been inspired to actually try putting it inside.

"Wow, cooool! It's going inside me!" Millie said after he'd only just barely started penetrating her.

"Uhh... yeah," Timothy agreed, somehow feeling a little embarrassed even though his little cousin's words were encouraging.

"Katie! Katie, look! Timmy's wee-wee is inside my pee-pee!" She said.

"Yeah," Katie said, a little unenthused even though she actually was watching rather closely. Her lack of enthusiasm had more to do with Millie acting like such a toddler about it rather than her actually not caring, she always wanted to show things off and they were very lucky she at least realized she shouldn't be saying things about them doing their privates game.

"I'm going to start pushing in a little deeper," Timothy warned. With the head of his penis already inside, he release his grip on Millie's privates and allowed the lips to snap closed over his shaft, and then rested both hands on her thighs, right under where his ankles were hanging over her legs. He applied some pressure on her legs with his hands for leverage, and while he'd intended to scoot himself forward, he actually wound up pulling Millie toward himself.

"Oh!" The little five year old kindergartener yelped when she felt her body inching forward. And then, she yelped a little differently when Timothy felt something strange and squishy inside her impeeding his progress.

"Ow! Timmy! That hurt!" She complained.

"Oh! Sorry," Timothy said and then backed off a little bit, a somewhat complicated venture due to the awkward position he was using to enter her. He wound up having to butt-walk backward, pushing slightly with his hands.

"There was something inside," he said, and then pushed himself forward again, this time a little more carefully. His penis gently nuzzled the barrier that was stopping him this time, gently poking against it. "Does that hurt?" He asked.

"A little," Millie replied.

"Alright, I'll be careful," Timothy said and began lightly rocking his hips back and forth, doing his best not to push against that membrane deeper inside her.

Katie watched as her brother was wiggling his penis around inside of their younger cousin, and it made her suddenly realize what he was doing. "Are you gonna try to make your weiner spit the white stuff inside her privates?" She asked.

"Uhh..." Timothy felt his ears grow hot from getting called on his plan.

"You're gonna spit in my privates too?!" Millie nearly yelled as she looked up at her older cousin.

"Yeah, it should be fine. It won't make a mess if it goes inside you," Timothy said and resumed thrusting around inside her.

"Hmm... ok," Millie said. She had immediately accepted his reasoning. She'd never complained about him getting the white stuff on her girl privates or on her chest, so she really didn't see much problem with him making his thingy spit it inside her. It seemed a little gross, but all of this privates stuff was fun and she figured this would be fun too.

Timothy's thrusts became faster as he became more confident, moving him ever closer to those weird feelings in his pelvis that always happened before his penis started spitting. He had begun poking that squishy bit inside Millie's privates a lot more frequently and with a bit more force, but Millie seemed to have more or less gotten used to it and was not complaining about it hurting since that one time with the initial surprise.

Actually, Millie seemed to be enjoying what they were doing a lot more. She was giggling more, and she'd even lifted up her hips and was thrusting back into him. This made it harder and harder to avoid poking at whatever that was inside her, and eventually it finally happened. There was one thrust where each of them miscalculated at the same time and she thrust herself forward hard at the same time as he was also thrusting forward at the same time.

The obvious happened, and his penis was suddenly a lot deeper inside of Millie's private parts as he had ripped right through whatever that barrier was. Despite his expetations and fears, Millie actually did not cry out in pain when he pushed through it. Instead, she just grunted a bit and continued rocking her hips back at him like nothing had even happened.

This encouraged Timothy and he started thrusting back at her even harder. He real quickly started ramming the head of his penis against something else even deeper inside Millie's privates. It was like she had another wall in her private parts after the first. This one did not elicit any complaints of pain from her though.

He was able to get around 3/4 to 7/8 of his 3.5 inches inside his little cousin now, and it was feeling a whole lot better having her entire privates wrapped around him now.

His thrusting got faster and more frantic as he felt the tight feeling of his privates trying to move the goey white fluid inside him, and then he let out a big groan as he started feeling his penis spurt and spit the stuff inside his little cousin.

"Are you doing it!? Is it spitting in my private parts?" Millie asks.

"Argh! Yeah..." Timothy says and has a somewhat mistified look on his face as he looks down at the little girl. Somewhere in their inept thrusting into each other, his penis had almost entirely disappeared into her five year old privates, even though the tip only just barely fit inside her at the beginning.

He had no idea how it seemed like her hole got deeper as they were doing it longer, but somehow it did. He realized he'd broken through the first wall inside her, and that accounted for a lot of the extra depth he got, but he also had encountered a second wall inside her. He could swear that "second wall" had somehow moved back and gotten deeper inside her as they were playing like this.

He also realized it felt really good to have his penis inside of Millie's privates too. Her warm insides seemed like they were massaging his thing from all sides at once. He'd definitely like to be able to have his penis inside of her, or perhaps inside of Katie or Kristen too, for a lot longer. However, he doesn't think he can stay that way, and now that he's finished shooting the white stuff he decides he should pull it out from inside her.

Millie just stared quietly back at him, seemingly not sure what to say or think as her older cousin pulled his penis out from inside her private parts he'd just filled with his white stuff.

The lips of her vulva closed back up after the intruder was out, and there was hardly even a sign of the activity they'd just done except for a little bit of redness from all the rubbing. It definitely made a much smaller mess since his penis spat the white stuff inside her instead of all over her body.

Timothy's penis, however, told a very different story. It was wet and slimy, but more importantly, there was a ring of red that looked like blood about half way down, around the same point on his penis where that first wall inside her would have been.

"Is your pee-pee bleeding Timmy?" Katie asked when she saw this.

"Huh? Umm... no, I think... I think this came from Millie's privates," Timothy said.

"My privates are bleeding!? Does that mean I have my period too!?" Millie says and looks down between her legs with excitement. When she does this, red and white fluids are squeezed out and leak from her privates, a mix of the white 'penis spit' and some more blood.

"Yeah, I am! I'm bleeding, I'm bleeding!" Millie says, sounding rather excited and happy about it. "Timmy! Put one of the period things inside me!" She says with a giant grin.

Timothy's not really sure about this, he felt like he might have actually damaged something inside of Millie's privates. But, she doesn't seem that upset and he really can't think of anything else he can do even if he did give her a scrape or make her bleed inside her privates. So, he does what she wants and gets out a tampon to stuff inside of her. Besides, this should also keep the white stuff from leaking out of her like that too, so it ultimately all works out.

-

After making Millie's vulva bleed, Timothy was too nervous to want to try playing with her privates anymore for a while. He did help her change her tampon a couple of times, and Katie too. He touched her down there when he was doing that. But, the third tampon he pushed inside Millie's privates came back out without a speck of blood on it. It did have a bit of his white stuff on it still, but there wasn't a bit of blood.

According to what Katie said about what they heard from aunt Angi, this meant she was done with needing the tampon and didn't need another one.

After all of this, he was not in the mood to try anything with his cousin Kristen when she got home from school, but it turned out the eight year old girl had other ideas.

"Hey, Timmy!" She said, coming up to him a few hours after she'd gotten home. "Millie says you gave her her period by sticking your weiner inside her!" She said.

"Inside her!?" His little brother Dillan said. "Like, what? In her mouth?"

"No, in her privates!" Timothy said.

"Yeah! Millie says he put his wiener inside her privates, and then she was bleeding just like Katie's privates were!"

"What!? Bleeding!?" He demanded. He had slept through the whole thing when Katie came into his room, and their parents didn't say much to him about it all, so it looks like he'd missed the whole thing.

"Can you do it with me too!? I wanna have my period too!" Kristen said.

"You wanna bleed from inside your privates too? Why!?" Dillan asked with a very confused tone.

"We can't do that right now! Our parents will be home from work any minute!" Timothy said.

"But I wanna have my period! Katie and Millie both have their period, and they're YOUNGER than me!" She nearly screams at him.

"Ok, ok! We'll do it tomorrow!" Timothy promised.

"Why do you WANT to bleed from your privates!?" Dillan demanded.

"Hmph! You're a boy! You wouldn't understand!" Kristen huffed.

"You're weird! Girls are really weird!" Dillain said.

He used to be involved in their privates games, but he'd grown tired of the game of showing his privates and having his privates touched. He also hadn't started shooting the white stuff yet, so the girls didn't quite find him as interesting and he also didn't have the need to make his penis spit that white stuff in order to keep from "having an accident" at night. So, he usually spent his time playing video games or something while Timothy took the girls to the bathroom to do things with their privates.

Anyway, now he had a promise to make Kristen's privates bleed tomorrow, so he'd have to look forward to doing that.

Part 3

Katie had also stopped bleeding by the time their parents got home. Aunt Angi had told their mom about Katie's period, so she came home with some new tampons for the little girl. These ones were a lot smaller than the ones they'd gotten from aunt Angi, she said that was all the little girl would need since she would not be bleeding as heavily as an adult would.

She'd also taken note of the box of tampons they'd been borrowing from their parents' bathroom, and also the number of used tampon tubes in the trashcan. Katie was scolded for this, saying she was using way more than was necessary and that she shouldn't just play by taking them out and putting in new ones.

But of course, since she'd only bled for one day, this wouldn't matter until the next time she started bleeding. They were told this would be happening more in the future too, about once per month, although she might skip a few at the start until she "becomes regular," whatever that means.

Timothy didn't really follow all of that so closely. The one thing that did matter to him was the fact that this wound up meaning he'd had to go to school today. It was a pretty average school day, but his mind was occupied with all the crazy stuff about his sister's privates bleeding, and then him accidentally making Millie's privates bleed too. And now, Kristen was going to want him to make her privates bleed too when they got home.

When the school day was over, he walked from his fifth grade classroom over to where Millie's after-school program was to pick her up. His parents had gotten him specially approved to pick her up, so that meant they could walk home together.

Kristen and Katie both met him at the door before he left the school. They were both in the second grade together, so they came out of the same classroom. Although Kristen was a year older than Katie, it was not a full year. In fact, Kristen's birthday was only a few weeks ago, and Katie was seven and a half, which she's been isistent to let everyone know ever since Kristen turned eight.

"Hey," Timothy said when he saw the two coming up on him. "So, should we wait for Dillan, or should we get going?" He asked.

"Let's go! I wanna hurry up and get home so... umm... so you can do what you promised!" Kristen said, meanwhile actually going up and grabbing Timothy by the wrist in her excitement and eagerness to get her period from him like Millie did yesterday.

"Uhh... yeah, alright," Timothy agreed. He had a hard time arguing with that kind of enthusiasm. Besides, there was also a good chance Dillan had already left on his own anyway. There were other times he'd done that when he'd had plans for all of them to walk home together. The only way they'd be able to know is if they poked their heads into the third grade classroom to see if he was there.

And so, the four of them left the school and walked home. It really wasn't far, they lived in a small community after all. The school building was also small, having only six class-rooms for kindergarten through fifth grade. The middle school was the next building over, and they shared a playground. Meanwhile, the highschool was across the street. Also, all three schools shared the same cafateria, which was also a separate building.

So, it was less a single small school building and more an entire small school campus that spanned the entire K-12 system of the community.

Even with this small community where everyone was within a child's walking distance of the school, their house was one of the closer ones. It was only about two blocks away from the school building. When they got in, just as Timothy had thought, Dillain was already home and playing a video game. He didn't even look up as Timothy and all the girls paraded through the main room of the house toward the bathroom.

All four of them crowded in there together. Kristen immediately started stripping off her clothes before the door was even closed while Katie and Millie found places for themselves to be a little out of the way. Millie sat on top of the closed lid of the toilet since she was small and light enough not to break it, while Katie took up a seat on the edge of the bathtub.

Timothy closed and locked the bathroom door, and by the time he turned around Kristen was already fully nude and she seemed to quickly grow frustrated when she saw that he had not even started undressing yet.

"Common! Take your clothes off, hurry!" She said egarly. After having gotten completely nude herself, she was unwilling to wait for her cousin to catch up on his own and ran right over to him and grabbed the front of his jeans, opening up the front with her clumsy little hands and then eagerly pulling them down to reveal his very stiff and drooling penis.

"It's already slimy!" She said excitedly and began playing with it. She used one of her hands to grab Timothy by the shoulder and stand herself up on her tip-toes, bringing the top of her slit almost up to his penis if she bent it down a little. This was one of the things Kristen liked trying to do, making his penis touch her privates while she was still standing. She held it over the other girls that she was tall enough to do this, even if she had to pull on his shoulder so hard that he was partly crouching to make it happen.

"Hey, hey! Stop it! You wanted me to give you your period, right? Just go lie down on the floor!" Timothy said, hastily warding off his eager little cousin before she made him topple over.

"Ok!" The hyper second-gradder chirped and ran back to the center of the bathroom and plopped down on the floor.

Timothy crouched down over her and got into the same awkward position he had with Millie, squatting down like a frog with his heels at her hips and his crotch in position against hers. He kept some weight on his feet this time, not fully settling his butt down on the floor. Instead, he used one hand to grip the sink counter in order to steady himself as he used the other hand to aim his penis. By now, he knew exactly where the hole the tampon's supposed to go in was, and he'd even had his penis inside Millie's hole before, so he was able to find Kristen's pretty quickly.

He pushed himself in a lot more easily than he had with Millie, something he attributed to Kristen being a few years older, but she turned out having the same wall inside her that Millie had all the same. This time, however, he had some idea of what to do.

"Alright, this is the part that hurts," he warned her and then pushed through that barrier in one go. Kristen's body jerked, but she didn't cry out in pain. Instead, she had a big self-satisfied smile. "Didn't hurt that much," she reported proudly.

Timothy wasn't sure if it really didn't hurt or if she was putting on an act, trying to prove herself to be the older and therefore tougher cousin over his sister Katie. Those two did have a bit of a rivalry centered around their age relative to each other, so antics like that were not uncommon for her.

Whatever. It didn't matter too much. Timothy decided just not to worry about it and sunk his penis all the way into Kristen's privates until he felt the second fleshy wall deeper inside her. He even pushed a little more once he did feel it, and this little bit of extra pushing managed to sink his penis all the way up into her until his ball-sack was touching the outside of her privates.

"Alright," Timothy said and started awkwardly rocking his hips in and out of her. He had to get into a position with his hands behind him while his feet were next to her hips in order to have any leverage at all. But, it really felt good to have his penis inside her private parts. Something about it even felt... right, somehow. The inside of her vulva wrapped around his penis, and although it was tight inside her, the feeling of pressure on all sides just felt soooo good!

He started to put more energy into the repeated bucking of his hips. He'd settled into something of a rhythm, and he could feel the familiar pressure inside his groin building fast as he knew he was going to be squirting the white stuff inside of her soon.

Timothy grunted and then pushed himself all the way inside of Kristen's privates as he felt his penis jerk inside her, spitting out the stuff all the way inside her. None of the girls complained or questioned what he was doing the entire time. Katie watched him do this with Millie yesterday, and they'd probably already told Kristen that him making his penis spit inside her was part of what 'gave her her period.'

Timothy let out a huge contented sigh as he felt his penis calming down. Kristen registered this as him being done, and immediately started scrambling to stand up, throwing off his legs as she slid herself backward and made his penis slip out of her.

She popped right up excitedly and stood with her legs bowed as she tilted her privates forward to look down at herself. Several pink-tinged gobs of Timothy's white stuff immediately dripped out of the little 8 year old girl's privates and splattered onto the floor.

"I feel it! I feel my period!" She cheered and thrust a hand under her privates to catch the next drop. She looked at the gooey blob of stuff in her hand afterward, studying the reddish-pink swirls within it.

"Cool!" Katie said, looking at the drips that had come out and onto the floor. "Hey, Timmy! Do me next!" She says, practically with stars in her eyes.

"But you already got your period, didn't you?" Timothy asks.

"Yeahh... but it looks like fun! I'm the only one who hasn't got to do it yet!" Katie responds.

Well, it's true. It actually is pretty fun. Timothy had to admit, it felt really good having his penis spit while it's inside a girl's privates. It feels a lot better than when he just rubs it on the outside, so if she wants to try doing it then he's alright with that.

"Now we can put one of those tampon things in me!" Kristen cheers.

And so, with an agreement reached, Timothy helped Kristen put a tampon into her privates. Meanwhile, Katie wiped up the drips of the white stuff that had fallen from Kristen's privates, and then she took off her clothes and got naked. By the time he was done helping Kristen, Katie was already naked and eagerly waiting for him.

"Come on, come on!" She said, pulling him by the arm.

"Alright, alright," Timothy responded, getting up from between his cousin's legs so he could get his penis between his sister's legs instead as she plopped down on the floor and eagerly bared her privates to him. By now, he was starting to gain a little confidence with this. It was already part of their routine for him to rub his penis on the girls' privates, so the difference of sticking it inside wasn't all that much.

The 11 year old boy sat between the 7 year old girl's legs and gripped his developing willy between his fingers and then quickly lined it up with the hole in the little girl's privates, and then he pushed it inside.

"Ow!" Katie yelped as her privates got filled up with her big brother's penis. Timothy had felt it, he'd ripped through the wall inside her, just like he did for Millie and Kristen. He knew it! He wasn't making them have their periods by putting his penis inside them, the blood was just from ripping through that wall.

"Uhh... yeah, it hurts a little when I put it in," he tells her.

Katie gives an irritated grumble in response.

"So, uhh... do you still want to do the rubbing game?" He asked.

"Yeah! Rub your pee-pee in my pee-pee until it spits! I wanna get penis spit in my private parts like Kristen and Millie!" She says.

He should have known, Katie has been really excited about the privates rubbing games lately for some reason. It was like some kind of switch was flipped and now she wants him to rub her privates or squirt her with the white stuff from his penis all the time, every single time their parents are out for even a little while. He wasn't able to squirt her with it much yesterday when she had her period, but it seemed like she was even more eager for him to touch her privates.

Timothy decided not to fight it, he just started bucking his hips forward into his giggling and grinning 7 year old sister. He knew it would take a little while longer since he'd already had his penis spit the white stuff inside Kristen, but he also knew there was no way Katie was going to accept that as a valid complaint of any sort. If anything, she'd just like it more that she got to have her privates rubbed for longer.

Just then, there was a knock on the door.

"Hey, open up! I gotta go pee!" The voice of his little brother Dillan sounded from the other side of the door.

Timothy slowed down his thrusting inside his sister as Millie, the only one still fully clothed in the bunch, stepped around him and Katie in order to get to the door.

"Daddy and our mommies aren't home, right?" The little girl asked. She knew she wasn't supposed to open the door while they were naked in there if their parents were home.

"No! School just let out Millie! Just let me in! I gotta go bad!" Dillan urged.

"Ok," Millie said and unlocked the door. Dillan burst in, and he didn't even spare a glance to his brother who had his penis inside his sister on the floor, or to his 8 year old cousin standing naked right next to the toilet. He just went over, pulled down his pants and started peeing, not even minding all his siblings and cousins being there to watch him.

The 9 year old boy had gotten used to them doing naked things together. He used to do it with them a lot too before he decided he'd rather be playing video games than doing naked games all day, and the girls had stopped pestering him when Timothy had started getting that white stuff coming out of his penis, which was like a cool new toy for the girls, and Timothy also started finding it more interesting to play with them too after that as well.

But, this time was different. When Millie saw Dillan, who was another boy with another penis enter the room, she saw an opportunity to not have to wait for her older cousin to finish before she had her turn.

"Hey! Dillan! Put your pee-pee in my pee-pee!" She demanded. She had already taken off her underwear while he was using the toilet, and now she was holding up her school dress and bearing her privates to him.

"What? You want me to touch your pee-pee with my pee-pee?" Dillan asked.

"Noooo! I said for you to put it inside!" She yelled back in a whiny voice.

"Like Timmy and Katie!" Kristen jumped in to clarify things for her little sister, pointing to her cousins who were on the floor. "Timmy figured out yesterday a boy's pee-pee can go inside a girl's privates, and it makes us have our period!"

"Huh? His is inside!?" Dillan asked as he shook off the last dribbles from his penis and then hopped over to where his older brother had his penis inside his little sister. Due to the awkward position Timothy had been using for this, it was very easy to see what the two siblings were doing.

"Oh, wow! It really is! Your privates are inside her privates!" Dillan exclaimed.

"Yeah!" Millie said. "He made it spit in my privates yesterday and then I had my period like Katie. It's really fun. You wanna do it?" She asked.

"Umm... Ok, sure, uhh... I can't make my wiener spit the white stuff like Timmy does though," Dillan said and started taking off his shorts with a hesitant look on his face as he glanced back at his baby cousin.

"Yaay!" Millie practically jumped in excitement as jumped past Dillan and laid down right next to her older cousin Katie. She behaved as though she did not even hear what Dillan had said at all. She just spread her legs wide and flipped up her school dress, putting her girl privates on full display.

As his little brother was figuring out how to get his penis inside their cousin, Timothy grinned down at his sister and he started rocking his hips back and forth again to move his penis around inside her, this time very conscious of his audience as he demonstrated what Dillan was supposed to be doing.

Dillan was a bit distracted by the sight, but he was also conscious of his little cousin Millie eagerly holding out her girl privates for him. He sat down between her legs and put his legs over hers, imitating Timothy's position with Katie. He took his penis between his fingers. It was still small, but he wasn't aware that would pose any sort of problem. He pressed it up against Millie's slit and started trying to find a way to go farther and push it inside her privates, but this turned into him just pushing the flaccid little worm into the folds of the five year old girl's slit.

"Umm... how do I make it go inside?" Dillan asks.

"You put it in the hole where the tampon goes during the period," Timothy answers

"Where is that though?" Dillan asks as he pushes his flaccid penis around in the kindergartener's slit a little more, although it is now starting to become a bit less flaccid from the activity.

"It's right here!" Kristen says as she boldly walks over between everyone, past the boys who are on top of the girls, and stands right over Millie's head so her privates are in front of Dillan's face. "It's there, the string is where the tampon is inside me!" She says, indicating a string dangling from the bottom of her slit. She also uses her fingers to pull open the two sides of her slit to show the inside where Dillan can see better where the hole inside her is.

"Ok," Dillan says. Fortunately for him, since he's mimicking Timothy's position, he is leaning backward and not forward. This allows him to simply look down and position his penis a little better so it will go inside Millie. His has gotten completely stiff in this time as well, so it winds up sticking into the little kindergartener easily. "Oh, it went inside!" He says.

"Yeah! Now you move around and make your pee-pee spit in me!" Millie says.

"But mine can't spit the white stuff!" Dillan grumbles at her. But, he does look down and think a little bit about this, how he's got his penis inside his little cousin, and the experience is so weird and cool he decides he would like to go along like this for a little while. The white stuff is just something Timothy does and the girls like him doing it. That doesn't mean he has to do it in order to play this privates game with them. He never had to in the past, after all. So, he starts imitating Timothy again and starts pushing his hips into Millie's privates.

Meanwhile, Timothy has begun making strange grunting noises and he is thrusting his hips at their sister Katie's privates faster and faster. He knows he's close, and after a few more seconds of this rapid thrusting, he gives a much louder grunt and stops as he begins filling up Katie's private parts with the white stuff.

He breaths out a satisfied sigh and takes his penis out of her privates once he's done, and the red-tinged white goo comes pouring out of her.

"Wow! You made my period start again!" She said, indicating the red stuff. "Oh! Tampons!" She said, and then reached for the cabinet where they were stored. This wound up meaning she had to reach directly over Millie as she was laying between her and the cabinets, and quickly discovered the little girl's body was blocking the bottom of the door as she tried to open it.

"Hey, Millie! Move out of the way! I need to get the tampon!"

"But I'm doing the privates thing with Dillan!" She protested. Dillan, however, was perfectly willing to move aside for his little sister's sake and immediately pulled out of his little cousin. It wasn't like he could make the white stuff anyway, so really he was just playing around by doing the same thing that Timothy was doing. He grabbed his little cousin by the wrist and got her out of Katie's way, allowing her to retrieve the tampons. She pulled out two of them, and then immediately handed one to Millie.

"Here!" She said, operating under the assumption Millie should be bleeding again as well since she just had Dillan's penis inside her privates. She then turned back to Timothy and handed him the one for herself.

Timothy knew what to do by now, all the girls asked for him to put the tampons in them. He opened the package and pushed the applicator up through the stream of white goo that was flowing out of Katie's privates and pushed the tampon inside her.

After she was finished, Millie stepped forward and handed him her own tampon, and then pulled up her dress again for him. He was starting to open the package when he noticed something.

"Huh? You're not bleeding!" Timothy said, and then reached out to pull Millie's 5 year old privates open with his thumbs.

"Huh? I'm not?" She said in a whiny voice.

"Hmm..." Kristen said, walking over to her little sister and crouching down to get a look at her privates as well. "Maybe it's getting the white stuff inside you that makes you have your period."

"I want the white stuff! I wanna have my period!" Millie chimes up immediately upon hearing this.

"Well..." Timothy said. "I... don't really think I can do it for all three of you, maybe later?" He offers.

"That's no faaaair! You gave Katie and Kristen periods, but not meeee!" She said.

"It's Ok, it's Ok! I said I'd do it later!" Timothy said.

"But... but we can't do privates game stuff when mommy, daddy, and aunt Dinah are home!" She whines.

"I... I'll think of something. If I can't think of anything then I'll do it with you first tomorrow," he said.

The little girl did not seem very happy with that suggestion, but Timothy eventually managed to convince her and she accepted it, although she was sulking for a while even after their parents got home.

Part 3: Sleepover

Timothy never did figure out a way to play the privates game with Millie later in the day. It wound up being the little kindergartener who had the solution. When it came time for her to go to bed, she threw a fit and said she wanted Timothy to sleep with her in her bed. Their mothers both tried to convince her, but she wasn't having it. Timothy realized what was really going on here though, and eventually he agreed. His mother and aunt Angi were a bit surprised and concerned, but most of that 'concern' was actually directed at how Timothy, being a boy, would probably not like sleeping in a room with a bunch of little girls.

"I mean, maybe if Timmy says it's Ok, she might be able to sleep in his room?" His mother suggested, but it was quickly countered by Katie and Kristen squealing in protest.

"Nooo! He can sleep in our room! That would be great! And then it would be like a big sleep-over with Timmy!" Kristen said energetically, getting an enthusiastic "Yeah!" from Katie. Meanwhile, the girls turned their pleading eyes toward Timothy, pretty much begging for him to agree.

He could guess at what was really going on. All of them realized this was actually the little kindergartener's scheem to get him to play the privates game with her and give her a period by spitting the white stuff inside her girl privates. The other two wanted to watch, and maybe even participate.

"Umm... it's alright, I'll sleep in their room," Timothy said.

"Are you sure?" His mother asked. "You know, the girls go to sleep pretty early, right?"

"I think it might be alright if the girls stay up a little longer tonight for Timmy's sake," aunt Angi said. "He's always being such a nice boy anyway, everything should be fine. Besides, tonight's a Friday. There's no school tomorrow anyway."

"Well, I suppose so," his mother said. "I guess you babysit them enough that it's not that big a deal for you, huh? Well, you can have them go to bed at something closer to their normal time if things get too annoying. Go ahead and enjoy your sleep-over with your sister and your cousins!" She said, and then that was the end of the discussion.

The girls squealed in delight and they all immediately started grabbing onto his arms and dragging him to their room.

"This is great! Timmy's sleeping over!" Kristen said.

"Yeah, yeah!" Millie said.

"We can all play house! Timmy can be the daddy, I'll be the mommy, and Millie can be the baby!" Katie said.

"Why am I the baby!" Millie protested.

"No, I'll be the mommy, cause I'm older!" Kristen interjects.

"Wait, hold on!" Timothy said. "I thought we were doing this because..." and then he dropped his voice down to a low whisper and motioned for them to all get their heads closer so they could hear, "because Millie wanted me to play naked and put my thing inside her privates and give her another period."

Millie's eyes immediately light up when she hears that. "Yeah! Yeah! I wanna get my period!"

"Ssssh!" Timothy, Kristen and Katie all three turn and shush the girl immediately.

"Oh... uh... sorry..." Millie says with a wilted expression. Meanwhile, Kristen and Katie turned back to Timothy, their faces a mix of excitement and worry.

"Can you really play the privates game now though?" Kristen asks. "Aren't our moms and dad home? We can't go to the bathroom together to play naked now!"

"Well..." Timothy says. "I was thinking, maybe it shouldn't be too bad if we do it with my wiener inside your privates. The white stuff doesn't make so much of a mess if it all goes in your privates, and then the tampons stop it from coming back out. We just need something to keep them from coming in and seeing us playing naked, so... I was thinking maybe we could do a fort or something."

""Really?"" Kristen and Katie looked at each other with huge smiles on their faces, while Millie just watched from the back.

"So does this mean I can get my period again now?" She asks.

"Yeah! We just gotta make a blanket fort first!" Katie answers for her brother before he can even speak up.

"Yesss!!!" The little girl does a dramatic fist-pump victory pose when she hears this, while the other two girls are already moving to get to work.

They chatter excitedly as they strip the blankets off the beds. They decide to use Kristen and Katie's bunk beds to make the fort process easier, but they can't just drop the blankets down the side to wall off the lower bunk and call it good.

They start incorporating Millie's bed as well. In order to prevent Millie from falling out of bed, their parents have arranged their beds in an L-shape, with Millie's bed pressed up against the wall and then hemmed in by the foot of Kristen and Katie's bunk beds as well as a dresser on the other side. The dresser also runs parallel to the bed, perpendicular to Kristen and Katie's bunks, completely walling off the lower half of the bed. The only way the girl can get in and out of bed is to crawl in from the foot of the bed to reach her pillow in the bed that uses a wall, her sister's beds, and a dresser as guard rails.

They heavily incorporate the dresser into the design. They actually decided to get bold and recruit their parents help for this. They had an idea for a design where they would close off the foot of Millie's bed and make it the "back" of the fort, and then designate the end of the bunks opposite Millie's bed as the "door." There was a little space between the other end of the bunks and the wall, and you could crawl in from that end.

With their dad's help, they actually moved a book-shelf into position and strung up a blanket between it and the dresser to close off the foot of Millie's bed, and then went on to also cover the top by using the fixture from a picture frame their parents had taken down a long time ago for fear it might fall on Millie if she got too rambunctious.

The "door" was a high blanket fixed to the top of the blinds on the window-sill. With a suggestion from aunt Angi, they also got more blankets to make their beds again, allowing them to actually sleep in the blanket fort.

When Dillan heard about what they were doing, he got jealous and actually wanted to join them for this sleep over. Their parents were cautious about this idea though. They may have not caught onto their children "playing naked," or if they did then they were deciding to play willingly ignorant. But, they were still keen to the personalities of their children and knew Dillan would likely not have a good temperament for hanging around the younger girls long-term.

At the same time, it would not be fair to simply exclude him completely. So, they reached a compromise. He could join them for a while and play in the blanket fort, but they would still have him sleep in his own bed back in his room. This wasn't an absolute rule, if he really wanted to sleep over in the girls' room, that was fine, but they were pretty sure he wouldn't be wanting that.

And so, all the preparations were complete and their parents left the room. The girls were really excited to get started, and they all crawled into the blanket fort and started crowding into the "back," where Timothy started taking off Millie's clothes.

"Alright, lets get started," he said.

"Huh?" Dillan responded. "Wait, you're gonna play naked here!?" he demanded in hushed tones.

"Yeah, this was the whole reason we were making the fort," Timothy said as he was getting Millie's underwear off her feet. He pushed up her dress, completely revealing her 5-year-old privates, and laid the little girl down with her head at what was the foot of her bed.

"Hey, Katie. Can you go get some tampons?" He asked as he started to pull down his own pants. The five children had seen each other's privates so many times by now that all of this was very casual to them, not even a cause for embarrassment. They were still conscious of being caught by their parents, but nudity between one another brought them no embarrassment what so ever.

It was perfectly normal to them to have their 11 year old brother/cousin expose one of their little girl slits for all to see, and just as normal for him to take out his own stiff penis. About the only things unusual about the situation were that it was in their own beds and that Timothy's penis was glistening a little with some kind of slimy fluid, but the latter part of that was not something they've never seen before. It happened sometimes when Timothy has been really wanting to play the privates-rubbing game with them and has been having to wait.

"I wanna stay and watch you put it inside Millie's privates!" Katie complained. "Maybe Dillan could get it?"

"I'll get it!" Kristen said, and then got a mischievous glint in her eye. "I'm gonna take out my tampon so I can play it too!"

"What?! No fair!" Katie calls after her close-age cousin as Kristen is already shuffling out of the blanket fort fast. Katie makes a frustrated noise and looks between Timothy and the direction Kristen had just left from.

"Hehe, it's alright, you can't both go into the bathroom with our parents home anyway," Timothy says as he's now crawling up over Millie who's looking up at him excitedly. "You can just wait until she gets back and watch me and Millie!" He says.

Meanwhile, he's considering how to actually go about sticking his penis inside of his little cousin. He knows the position he's been using so far is very awkward. Most of the reason he'd been doing it that way is because he didn't want to hurt his knees on the hard bathroom floor. But, now he was on Millie's bed. He didn't have that problem anymore. This gave him more possible options, but he wasn't really sure what would be best.

"Alright, I'm gonna try it like this," he said and sat with his knees together between Millie's legs. He grabbed the little kindergartener by the legs and pulled her up onto his lap, electing squeals of glee from the little 5-year-old. "Hey, hold still!" He chastises her as she's moving around too much, making it difficult for him to line up his penis with her little vulva.

She eventually gets the idea and settles down a bit, and Timothy is able to get his penis inside her. After that, he discovers he has to re-position his legs a little bit in order to begin thrusting. He spreads out his knees, and then folds his body down over top of her and starts pushing and grinding his hips into her with a lot more leverage than he was able to get before.

His thrusts become strong and fast, with Millie letting out little happy "gee" sounds, like a mix between a giggle and a grunt in a way only a child her age could do, with a huge grin on her face every time he plows into her.

By the time Kristen gets back with the tampons, he's already thrusting into her like a jack-hammer, and he is able to finish and get his penis to start squirting a lot faster than normal as a result of all the extra stimulation he was able to give himself as a result of this new position. He lets out a grunt and a groan, and then partially collapses over his little cousin for a moment before straightening himself back up.

He pulled his thing out of her, and stared down at her privates for a short while.

"Huh, the white stuff isn't leaking out," he commented as he observed the state of his little cousin's private parts. Indeed, not even a trickle of his white goopy stuff was leaking out of her. He didn't know a lot about what determined the amount of the white stuff that came out of his penis, but he did feel he hadn't made as much of it as usual this time. He accredited most of this to it being the third time he did all this today.

"Does that mean I don't have my period?" Millie asks as she looks down at her own privates.

"I think maybe it only happens the first time," Timothy suggests. He felt pretty sure he wasn't actually giving the girls their period at all. He'd felt like something was ripping inside them when he stuck his penis in, and he was pretty sure the blood was coming from that thing that ripped. He hadn't felt it inside the second time with Millie, and he's only done it once before with Katie and Kristen.

"Uhh... hey, Kristen! Take off your underpants. I want to try it with you next," he said, wanting to test the thought going through his head.

"Awesome!" Kristen cheered and immediately jumped out onto the head of Millie's bed and started wrestling with her skirt and pushing down her girls' underwear as Timothy was turning around to crawl over to her.

"Hey, what about me!?" Katie complained.

"You can do it with Dillan!" Timothy said.

"Don't you still gotta take your tampon out?" Kristen asks.

"Oh! Right!" Katie says and then starts crawling off away from the beds.

Meanwhile, having learned from his experience with Millie just now, Timothy placed one knee on either side of Kristen's hips as he took his penis in his hand and started guiding it toward his 8-year-old cousin's slit and found the hole where he could put it inside her vulva.

He confirmed his suspicions from before. He didn't actually feel any wall of stuff inside the older of his female cousins either. But, he decided to keep thrusting inside her, if for no other reason than the fact he got the distinct impression she would complain if he didn't rub it inside her for a while.

Millie was now sitting upright as she watched them. The skirt of her dress had flipped back down, and now you couldn't tell she was naked underneath since the skirt covered her up. She and Dillan watched as the two of them were squirming around against each other while Katie was still absent from the room. Timothy with the focused pursuit of making his penis squirt again, and he was starting to notice this was causing a change in Kristen.

"Ahhh! This is starting to feel good!" Kristen said.

"Yeah..." Timothy agreed, a little distracted in his tone as he was too focused on thrusting at his younger cousin.

"It feels really nice with... with the boy things rubbing inside my pufa!" Kristen says.

"Pufa?" Millie says. "Do you... do you mean your front-bottom?"

"Yeah! That's the name for it!" Kristen says.

"Actually, uhh... I think it's supposed to be called a vulva," Timothy interjects.

"Yeah, yeah! That! Vulva!" Kristen says.

"Actually, umm... how about we call it a pufa?" Timothy suggests. "Maybe mom, dad, and aunt Angi won't know what we're talking about if they hear us calling it that."

"Ok!" Kristen agrees. "Hey! How about that? How about we call this game with the boy things in our girl things the pufa game?" She suggests.

"Yeah, I think that's a good idea!" Timothy agrees.

Kristen has a huge self-satisfied grin on her face as she has planted her feet on the bed and is now bucking her hips back up into Timothy with every thrust he makes, and they are both getting sweaty with the activity of thrusting into each other.

This goes on until the door opens and then closes quickly behind whoever just came in, causing them to have to pause for a moment and listen until they confirm the footsteps they are hearing are hearing do not belong to an adult. Kristen has gotten back, and they hear her pause for a moment in the middle of the room before making a dash for the "door" to their fort.

She barrels on through and on the way she grabs Dillan's hand and pulls him deeper into the fort, past where Timothy is playing 'the pufa game' with Kristen at the head of Millie's bed, and goes to the foot of the bed where Timothy had previously done it with the little 5-year-old.

"Ok, quick! Pull your pants and underwear down!" She urges as she starts messing with her older 9-year-old brother's pants. Once she fishes his penis out, she flops onto her back and flips up her skirt, spreading her legs and revealing why it was she paused in the middle of the room before coming into the fort. It looked like she'd already removed her underwear and was already naked under her skirt.

"Oh, hey! Katie!" Kristen said. "By the way, we decided we are calling this the pufa game, Ok?" She said.

"Isn't that the name for the girls' privates?" Katie asks.

"Actually, it's vulva, but they decided to call it the pufa game so maybe mom, dad, and aunt Angi don't know what it is we are talking about," Dillan says.

"Oh, ok!" Katie agrees and goes along with the idea. "Anyway, come on! Start putting your thing inside!" She urges and grabs her brother by the penis and starts actually pulling him forward to push him against herself.

"Alright, alright! Jeez!" Dillan says as he's forced to deal with his little sister's enthusiasm for their newly dubbed 'pufa game.'

Meanwhile, Timothy has decided to re-focus himself back on his thrusting with Kristen. He is trying with all he's got to make his penis spit the white stuff again, but he has already done it several times already today and it's not coming easy, and the time he spent worrying about what Katie and Dillan were doing only distracted him.

He heard Katie giving frustrated instructions to their middle brother from time to time, but he was too focused on just thrusting at a fast and sustained pace and on the reactions it was causing for his cousin Kristen. She moaning and thrusting back up at him as much as he was thrusting at her, and she was starting to sound like she was having a lot of fun doing this.

"Oh... oh yeah! Oh yeah!" She kept moaning as she thrust into him. Then, all of a sudden, she just stiffened up and let out a squeal. It seemed more like she wanted to scream, but she was doing everything she could to keep it quiet. She even clamped her hands over her own mouth.

At the same time, Timothy felt the insides of her girl privates squeezing down on his penis from every side, and something about her suppressed squeal sent a chill down his spine, and that chill rippled down through his pelvis and into his groin where it triggered a reaction, finally pushing him over the edge.

His penis was squirting again. He was filling up the inside of Kristen's privates with more of the white stuff. It felt different than when he'd done it with Millie. It wasn't quick and over with like it was with her. With Kristen, it felt like it was really doing everything it could to scrape out every bit of the remnants of the white stuff it could pull out of him. It felt painful, like it was scraping out something from the inside of his ball-sack with every spurt of the white stuff inside her.

He immediately flopped over onto his side when he was finished, laying next to Kristen in a quivering wreck. That had all been just... well, a lot! It had felt good! He couldn't believe how good it felt. But, it also felt exhausting. He was tired, and his body was still twitching from the experience. He really didn't like that part.

"Huuuah! I'm so tired!" Timothy complained.

Kristen sat up and looked down between her legs after Timothy had finished. She also was not leaking any of the white stuff he had squirted in her, and also had no blood.

"I didn't get my period either," Kristen says. "Did your pee-pee spit out the white stuff?" She asked.

"Yeah, it definitely did!" Timothy said. "I just... I guess maybe I didn't have much to spit out. Kind of like trying to pee when you don't gotta, but you still squeeze a little out."

"Hmm... Ok," the little girl said with a shrug and then found her underwear that had been removed earlier and put them back on. When Timothy saw this, he also started getting dressed himself. Meanwhile, Katie was still egging on Dillan to keep pushing his penis in and out inside her while the little boy was starting to look a little bored of just rocking his hips in and out.

Around this time, the door to the room clicked open, and everybody knew it was one of their parents since they were all already in the room.

"Hey, nobody better be jumping on the bed in here!" Timothy's mother said, causing all the kids to freeze in realization that they were in a dangerous position right now.

"We're not!" Millie speaks up in protest immediately.

"Uhh... yeah, we're not, mom!" Timothy manages to squeeze out the words.

"Ok," his mother says with a still suspicious tone in her voice. "I heard a lot of the beds squeaking though. I know we all let you have fun in here together, but I don't want you breaking any of the furniture," she said.

"Ok aunt Debora," Kristen says, with a quick "Ok mom," echoed by Timothy, before his mother seemed to be satisfied and slowly left the room.

The entire time, Katie and Dillan had been frozen in place, dead silent, clearly freaked out at their mother walking into the room while they were in their state.

"I... I don't think we should keep doing this," Dillan said, getting no complaint from his sister as he pulled his penis out of her.

The two of them got dressed, and then Timothy had Millie put her underwear back on. She had also been bare under her skirt when his mother walked in. It is a very good thing they'd set up this fort or else they'd have been caught for sure.

Soon after that, Dillan went back to his room, and Timothy had a very awkward and uncomfortable night sleeping in the girls room. Half way through the night, he just couldn't stand it anymore and decided to go back to his own room.

Part 4: Truth

After that night, the kids had discovered that their so-called "pufa game" was a lot easier to play on a bed than on the bathroom floor, and it became their new default to play like that when their parents were out.

Months had passed with them continuing like this. There was also a while where Katie started throwing up in the mornings. Their parents had let her stay home for the first couple of days, having Timothy stay with her as usual. She tended to feel fine later in the day though, and they would play "the pufa game" a lot on those first few days. However, Katie kept throwing up for a long time, and now their parents started to actually worry.

They brought her into the doctors, but they couldn't find anything really wrong with her. Eventually, they started having to send her to school anyway even when she was throwing up in the morning. She even wound up canceling her birthday slumber-party plans because she knew she was probably going to throw up in the morning and didn't want all her friends around for that.

This mysterious illness continued even into the summer after school ended, and Kristen also started getting sick like that too around the end of the school year.

Katie has also been getting fat for some reason. Her belly has been getting bigger and bigger. It makes her look like she's pregnant, but she was only eight years old now, so the rest of them knew that couldn't be right.

Their parents grew increasingly concerned about it though, and eventually, their mother took Katie in to the doctor again while dad and aunt Angie were at work.

When they came back, all of us were sat down and all three of our parents had a very serious talk with us. It turns out, Katie really was pregnant. They also had Kristen pee on this weird stick, and it said she was pregnant too.

All of us were confused as to how this could have happened, but then they explained to us how babies are made. It turns out, "the pufa game," as we'd been calling it, is actually something called "sex," and sex is how a boy gets a girl pregnant. This explanation was immediately followed up by them questioning if me or Dillan had ever done this with the girls. There were a lot more conversations after that.
