Phineas & Ferb: Phineas' Harem

Phineas and Isabella fucked nearly every day of their summer vacation. Sometimes at his house, sometimes at hers, sometimes somewhere where there was risk of being caught, like at the park. Tonight, it was at Isabella's house, and Phineas, tired and hungry, had just narrowly escaped after a marathon of fucking that began early that morning.

It was getting close to nighttime by the time Phineas managed to leave. It took another few hours worth of vigorous fucking and making Isabella cum over and over again before she fell into a sex coma and he could extract himself from her arms; she loved to cuddle after sex, and had the death grip of a python.

Phineas unlocked his front door and stepped inside to a dark and quiet house. He paused in the threshold. This was odd; he knew his dad was working late tonight, but then why were all the lights off? Maybe Candace, Linda and Ferb went out to see a movie? If only he could have escaped Isabella's clutches sooner. He's be sure to punish her later for that.

Phineas went over to turn on the light, but as his finger was inches away from the switch, his ears perked up. He could hear activity in the house. It was coming from upstairs, like some massive weight was shifting around slightly. He followed the noise up the stairs and down the hall. It was coming from his parents' room. There was a light emanating from the crack at the base of the closed door, and as he approached it, he could hear moaning and heavy breathing on the other side.

"Did Dad come home early?" he asked himself. His heart started to race. He was very intimately familiar with the sounds of sex at this point. Ever since he started having sex, he fantasized frequently about his milf of a mom, but he never got an opportunity to see her ride a cock or buff the muffin. His dad had a pretty low sex drive, though, and as far as he knew, they were a split bed away from being an I Love Lucy couple.

Phineas' head started to feel a little hot. He took a deep breath. This was a one in a million opportunity. He had to be extra silent and not blow it.

Silently turning the knob, Phineas slowly pushed open the door, grateful that the hinges on all the doors and windows were oiled recently. Phineas mentally braced himself for the first sight he may see being bouncing hairy dad ass.

He did not expect to see what he did.

Opening the door just a crack, Phineas saw Candace and his mom Linda naked on the bed facing each other. There was a small boy beneath them. Their cock was in Linda's pussy, and they were currently eating out Candace's pussy, based on the expression on her face. The glimpse of a tuft of green hair poking out from between their tangle of legs was all Phineas needed to know that it was Ferb.

Phineas stared at the scene in the room with a mixture of emotions. Jealousy ultimately dominated all of them. How in the hell did Ferb get to plug their mom's pussy?! How long was this going on?! And most importantly, why wasn't he invited?!

Phineas considered running in, ripping off his clothes and pouncing on his mom and sister like a beast of legend, but he knew that it was just as likely to not work. He exercised considerable restraint to not give in to his base instincts, then backed up and considered his options.

If he took video of the event, he could have something to hold over Candace and Linda. Then he could have his way with them any time he wanted. He pulled out his smartphone. The battery was getting low, but there was still enough power in it for a few minutes of film.

"Smile, you're on candid camera." he sang quietly to himself as he activated the record and pointed it through the crack in the door.

"Uuhh! Huuuuhhh!" Linda moaned. Her body glistened with sweat, and her breasts bounced along with her. "Good boy, Ferb! Your dick is pleasing mommy so much!"

"Huuaaaahh! His tongue is digging inside me!" Candace gasped. Her eyelids flickered and her body trembled as she was very clearly having an orgasm.

"My dick could please you even more, dear sister..." Phineas muttered sinisterly. "As for you, mom... what would dad think if he saw you like this, fucking your own stepbrother? Bet he'd be pretty devastated, getting cucked by his own son, whose balls haven't even dropped yet."

The sight of his family engaged in a threesome made Phineas form a noticable bulge in his pants, though he did his best to ignore it. He merely crouched there in the doorframe, holding the smartphone steady, and stewing in his own arousal and jealousy.

"AAAHNNNGGG! MMmHHNnnhhgh!" Ferb's voice suddenly cried out amongst the din of moaning. He twitched violently underneath his stepmom and sister as he came. Phineas could feel his blood boiling as he saw his brother-in-law's white viscous baby batter ooze out of their mom's pussy. That should be Phienas' jizz inside her, and his tongue inside Candace.

Of course, after tonight, that is how it would be from now on.

Legs clearly trembling, Linda pulled herself off of Ferb and licked his dick clean of all the sexual juices that coated it.

"Come on, mom. Now it's my turn." Candace said, trying to push Linda aside so she could plant herself on Ferb's lap. The phone's battery was too low by this point to continue recording, though Phineas had everything he needed. He slipped the phone out of the crack in the door and made his way back to his room. After putting the smartphone on the charger, Phineas laid down on his bed, too lost in his thoughts to take care of the massive erection he had. All he could think of was Linda and Candace's naked bodies, and how he would approach them with the film to ensure the next body underneath them was him.

• * *

Phineas woke up the next morning with the feeling that today was going to be a great day. He thought long and hard about his plan of attack until he fell asleep, and when he woke up, his plan was laid out clear for him.

After taking a shower and getting dressed, Phineas headed downstairs. Inside the kitchen, Candace was sitting at the breakfast table, lazily flipping through something on her smartphone as she had her morning coffee.

"Where's mom?" Phineas asked as he poured himself a glass of orange juice.

"She and Ferb went to the store." she said dismissively.

"Really?" Phineas asked.

"Yes, really. Now leave me alone, I'm checking my news feed."

"While you're at it, take a look at this great viral video I found." Phineas said. He sent her the video he recorded last night. "It really made me laugh out loud."

"Is this another one of those fucking stupid Mick Spins? Because I swear to god if it is, I'm going to deck you."

"No no no, you'll love this one." Phineas assured her, a sinister tone creeping into his voice.

Candace thumbed at the screen a few more times. Her narrowed eyes widened in shock as the video started playing; she quickly and instinctively fumbled for the volume control as the sound of her own moaning emanated from the tiny speaker.

"WHAT THE FUCK!?" she exclaimed. "What did you... when did you...?!"

"You really should have figured out a better way to hide your... affair, I guess is a pretty apt word." Phineas explained. "I came home early last night."

Candace's face flushed a deep red, and she looked back and forth between the video and Phineas.

"Wonder what Jeremy would have to say if I sent him that video? Wonder how he'd feel about getting cucked by a kid still in elementary school?"

He stared depraved daggers into her. He didn't plan for what he would do should his gambit backfire, but there was no coming back out of the deep end.

"Fine, what do you want?" Candace asked through gritted teeth, turning off the video. "What will it take to make this thing go away?"

"Glad you asked. Come with me." Phineas ordered. He led Candace to the living room.

"Strip, and then sit down on the couch." he ordered.

"What are you looking to do, you little perv?!" Candace demanded.

"Do as I say, or I'm sending that video to Jeremy and all your other friends. You slutty brotherfucker." Phineas retorted. Candace clearly would have loved to retaliate against him in some way, but her hands were tied. Reluctantly, she pulled off her clothes, starting first with her shirt, and then her pleated miniskirt. To Phineas' surprise and immense pleasure, she wasn't wearing any underwear underneath.

"Were you expecting to ride Ferb later today or what?" he asked.

"Tch, maybe. I usually like to go commando." she answered defensively.

"Or so you say. Now get on the couch." Candace did as she was told. After she sat down, Phineas came over and spread her legs far apart so he could get a good view of her pussy. He spread the labia far apart with his thumbs. He was surprised at just how flexible they were; Isabella could barely take in his length without wincing.

"So how long has this been going on?" Phineas asked.

"About the time summer vacation began." she answered through gritted teeth.

"So what, was Jeremy just not doing it for you?"

"He... is not so good in bed as you might think."

"And you didn't think to invite me?" Phineas moved his thumb over her clit and rolled it around. Candace gasped and tensed up.

"AH! Y-you're my brother!" she gasped.

"So is Ferb."

"Not by blood! It's different!"

"Hm. Well that's just your opinion." Phineas backed up and proceeded to throw his own clothes to the ground. Candace had a look of helplessness on her face, still fully aware that running away now would carry serious consequences. She ran through every possible scenario through her mind, trying to think of a way to get out of this mess and get access to the source of that video so she could delete it.

Her train of thought, however, was derailed once she got an eyefull of the dick that Phineas was armed with. He was smaller than Ferb, but somehow, his cock appeared to be even bigger than their brother's! How was that even possible?! It definitely looked big enough to stretch her out, possibly to her limit...

"Like what you see?" Phineas asked. Candace came back to her senses and looked up at him.

"Duhg-beih-NO! I'm just... wondering what Isabella has to say about sucking on an uncut dick." she said, clearly lying.

"If you must know, she loves it. Now don't you dare move a muscle or I'll make sure you are number one trending by Sunday."

Candace did as she was told, though she was fairly certain what was going to come next. Phineas pulled her closer to the edge of the couch, so her butt was teetering close to the edge. She put her hands on the seat on either side of her to brace herself. Part of her wanted to kick Phineas in the face. The other part of her was curious about how well that dick would feel inside her, and to her dismay, the latter side was winning.

Phineas moved in between his legs, guiding his dick with one hand to her pussy lips. The heat coming from her was like an oven. With one hard thrust, Phineas pushed between the plump, fleshy lips and buried his dick to the hilt inside his sister.

"FUGHGH!" Candace gasped. Her vaginal muscles tensed up all around the cock, and she was shocked at how big it felt inside her. The head was pushed right up against her cervix, and the girth felt like she was going to be split in half!

If that wasn't enough, the insertion seemed to have pulled the foreskin back on Phineas' cock, and the ridged head was pushing up against the wall of her bladder, just behind her G-spot. She knew very well that the instant Phineas started moving, it was going to stimulate her G-spot, and she was not going to be able to resist him any longer.

Her greatest fears turned out to be true. Phineas pounded into her with the ferocity of a dog in heat. The extremely prominent ridge of his penis's head rubbed against her G-spot with every pass, sending a hot electric shock through her nether regions that sapped her of what little resistance she possessed.

"HUUHH! FU-HUUUCK!" Candace moaned.

"Yeah, you love that, don't you?" Phineas growled. He grabbed both breasts and used his thumbs to press and roll the nipples around. The instant he touched her nipples, he could feel her vaginal muscles tense up even more around his dick.

"Yuh... YES!" Candace cried out. "Keep going! I'm so close!"

"You don't mind cumming from your brother's dick?"

Candace shook her head. Her eyes were closed shut. Her muscles were tense under Phineas' touch; she must be trying to hold back her orgasm. Phineas should have been offended by this, as it implied that she was lying to him, but instead, he took it as a challenge to overcome her will and self-control.

Phineas moved a hand down to her clit, gently pinched it between the middle of his middle and index fingers, and tugged it around. The instant his fingers touched the sensitive flesh, Candace's muscles contracted even more. Phineas suddenly felt something from behind push him closer up to her. Candace's legs wrapped around him and held him in place so he couldn't pull out even if he wanted to. He couldn't even pull an inch out of her to continue thrusting, so he changed his tactic and ground into her in such a way that the head of his dick rubbed against her G-spot.

"UUGHHUGGHNNNGHH!" Candace gurgled as her orgasm overwhelmed her sense of control. Her eyes rolled back in her head and she spasmed underneath Phineas. Her vaginal muscles were quivering so much, it felt like it was vibrating.

"Hhnnghhh FUCK! HAAAAHHH!" Phineas grunted. He shoved his dick in as far as he could and arched his back. He shot his load into his sister, each spurt of cum nearly as voluminous as a full orgasm with Isabella. Was it because she was more developed or because she was his sister? Or maybe he was getting off from the idea of blackmailing her like this? Whatever the case may be, he was enjoying this a hell of a lot more than he thought he would.

By the time Phineas settled down, he was actually feeling dizzy. Candace lay back on the couch, dwindling on the verge of consciousness. Her legs were starting to slacken, and he managed to pull himself out of her. To his delight, his cum was oozing out of her all over the couch. He loved the sight of the aftermath when he did it with Isabella.

"Suh... satisfied now?" Candace hissed, staring daggers into Phineas with half-open eyes.

"Hmm, maybe." Phineas said as he gathered up his clothes. "Though I think you owe more than a little backpay."

"You can't fucking be serious."

"Try me. We can negotiate my terms later." Phineas said coyly. "By the way, I would recommend cleaning up as quickly as you can. If you are right, mom and Ferb should be coming home soon."

With that, Phineas left the room, leaving Candace to worry about cleaning up the mess of spooge on the couch.

• * *

Candace didn't see Phineas for most of the day, and good riddance. She resisted the urge to deck him right in the face the few times she did. The consequences would be disastrous, however, so she stayed her hand.

Candace went to bed thinking that she would probably get approached by Phineas tomorrow. She didn't realize, as she fell asleep, that she was half right. Around midnight, Phineas snuck into her room. He was completely naked, his dick erect between his legs. It bounced with every step.

Phineas silently closed the door behind him and pulled back the sheets over Candace. She was only wearing pink panties and a matching camisole. They looked pretty nice on her, but ultimately they were only a bothersome obstruction.

Phineas pulled Candace's panties and spread her legs far apart. She stirred slightly, but didn't awaken. Phineas probed her pussy lips with his dick. He was already dripping with precum from the anticipation, and it made pushing into her much easier. He paused briefly once he got the head of his cock into her, he thrust in as hard as he could, Causing Candace to awake with a start.

"HUUGHH! Wh-WHAT THE FUCK ARE YOU DOING!?" She exclaimed as Phineas began vigorously fucking her.

"I'm just planting some gardenias- what the fuck does it look like I'm doing?!" Phineas retorted as he pounded his dick into his sister.

"Phineas, if you don't pull out of me right now, I'm going to scream." She threatened.

"Scream all you want. I had your room soundproofed months ago so I wouldn't have to listen to your awful teen band garbage." Phineas said. "Besides, you know you love this!"

The worst part is that he was right. Phienas' dick was shaped just right for her uterus. The head persistently ground against her G-spot, which made her crotch tingle. This is what she was missing from her relationship with Jeremy, and if she wasn't related to Phineas, industrial-strength douchebag behavior besides, she might be far more into this.

'Come on, just get it over with so I can go back to sleep.' she thought to herself, even as she felt her body starting to warm up from the stimulation. Phineas grabbed at her camisole and pulled it up over her breasts.

"You have such amazing tits." He said, grinding his hips into Candace as he groped at the soft mounds. "Do you let Jeremy suckle on them?"

"Th-that's none of your business!"

"You do, don't you?" he asked. He moved his head down and closed his lips around one of the nipples. Candace gasped and arched her back up into him, and her vaginal muscles tightened their grip around his dick.

"Heh heh, guess that answered my question." he said, then proceeded to suck on her nipple and tease it with his teeth. Candace's eyes flickered and she thrashed around underneath her. Unfortunately he locked onto one of her more erogenous zones and was mercilessly stimulating it. Her breathing hastened, and she found it difficult to resist him anymore.

'Come on, just hurry up and make me cum so I can get back to sleep.' she found herself thinking. Her pubic muscles were quivering with excitement. She was so close to her orgasm, she didn't care if she was being raped or that it was her own brother doing it. She just wanted to feel the climactic bliss again.

Phineas picked up his pace. Based on his frantic thrusts, he was getting close to his orgasm, too. Their combined sexes were making loud, wet slapping noises, like someone stomping around in boots in a pool of mud.

"Hhnnhhh HNNNHH HUUAAAAHHH!" Candace cried out. She arched her back as she hit her climax, and she subconsciously wrapped her legs around Phineas to trap him inside her.

Phineas ground his hips into her even after he came. The tip of his dick flared up with an electric burning sensation. He could feel his sperm gushing out in incredible volume. As he came down from his orgasmic high, the strength in his arms left him, and he collapsed on Candace's chest. Both their bodies were covered in sweat. The smell of sex was strong on both of them.

Candace should have been more angry at Phineas, and she might be in the morning, but she would be lying if she said she enjoyed it. She only wished that he would pull out of her before he came. She did not want to use her morning after pills because of Phineas, especially if this was going to be a normal thing with them.

Candace lay there with Phineas on top of her, waiting for sleep to take over again. Her vision began to darken before she was jostled back awake by a powerful force knocking into her body and her pubis tingling with delight again. It took a few seconds for her to register the form of Phineas hovering over her, a sadistic look on his face as he resumed fucking her.

"What the- wasn't the first time enough, Phineas?!" she exclaimed.

"I took one of dad's blue pills before I came in." he growled between breaths. "So we're fucking until it wears off."

'Son of a-, and that could be hours!' Candace thought. Her second orgasm of the night soon rocked her like a tidal wave. At the same time, a different sensation of relief washed over her, and Phineas let out an exclamation of surprise as his abdomen was drenched in a splash of clear, musky fluid.

"Oh wow! I didn't know you were a gusher!" he said. "You must really enjoy this!"

"Fuhh... fug!" Candace tried to say "Fuck you!" to Phineas, but her brain was sluggish after two orgasms without much respite between them. She watched helplessly as Phineas came to a second orgasm as well. Another hot load of sperm filled her up. His dick and her pussy were smeared with sperm, worked into a mild froth from the repeated thrusting.

'Please be spent, please be spent...' Candace thought, but as Phineas' grip tightened around her waist, she swore to herself in futility.

Phineas continued to fuck Candace for most of the night. It wasn't until it was nearly four in the morning that he had finally reached his end. Candace was a mess on the bed. Her hair was completely matted down with sweat, along with the sheets beneath her. Phineas' cum oozed out of her, further staining the sheets. The smell of sex was so thick in the air, you could cut it with a knife. Candace's mind was fragmented and numb from the aftershock of one orgasm after another.

Phineas staggered out of the room, exhausted but very content and satisfied. He knew he was going to be sore in the morning, but it was worth it.

"Good night, Candace." he sneered as he shut the door behind him.

• * *

"Hommu fug, varff's fo awfum!" Isabella mumbled as she sucked Phineas' dick. It was a few days after Phineas' encounter with Candace that he finally told Isabella the story. He was so sore after his multi-hour marathon that he had to hide from Isabella for a few days to let his dick recover. Sure enough, when he went to her house, she had his pants down and her lips wrapped around the shiny pink head within seconds.

"Don't talk with your mouth full, Izzy." Phineas chided, though he immediately regretted this as Isabella pulled away and clutched his cock and balls in each hand and gave them a gentle squeeze.

"Then don't call me Izzy." she said coolly. "That name reminds me of that one boy from the show with the holographic monsters."

"Fine, fine!" Phineas hissed through gritted teeth, and Isabella loosened her grip on him and resumed sucking him off.

"So Candace is wrapped around your finger." she said, popping his dick out of her mouth to speak this time. "What now?"

"Now I'm gonna get mom." Phineas explained. "She probably started all this, and roped Candace in in the process."

"Alright, but when you make your move, I wanna be there, too."

"Oh ho! Interested in watching me fuck my own mom?"

"Who says I was content on just watching?" she asked. "I wanna make your mom squeal, too!"

"Hah! I'd pay to see that!" Isabella climbed onto Phineas' lap and set herself down on his dick. She lifted the hem of her dress up so he could see it prod against her drooling pussy lips.

"Oh yeah, that reminds me." Isabella said as she let the dick push into her young preteen folds. "I took a pregnancy test the other day. It came back positive! You're going to be a daddy!"

"Awesome!" Phineas exclaimed, pushing her down onto the couch so he could fuck her properly. "What do you say we give them some siblings as well?"

"Oh, you plan on going through with that plan on stealing your mom and sisters' contraceptives?"

"Absolutely! We'll have to also break them of the habit and want to have my babies."

"So what's the plan?"

Phineas explained the plan to her as they continued to fuck. He had to occassionally shock her back to alertness by flicking her clit whenever she would get too mired in the bliss.

"Okay, okay, I get it now!" Isabella exclaimed after the third time Phienas had to draw her attention again. "But what are we gonna do about your dad? He's gonna find out, eventually."

"Actually, I've been thinking about that. I think it's time for him and Ferb to go. I just... need something on him."

"Oh is that all?" Isabella asked. "Well, you're in luck. I just happen to have something particularly juicy that I've been holding onto."

"What is it?"

"Oh, some months back, your dad might have had a run-in with one of the Fireside girls - Gretchen, if you're curious - and I might just have a recording of it."

"You're kidding! How did that happen?"

"Eh, don't sweat the details. Point is I have it on my phone. I'll show it to you later."

• * *

The following week, Phineas decided to make his big move. His heart was racing every time he thought of the plan. There was always the chance this could just blow up in his face, but if it did, he could probably invent a time machine and make another attempt.

The following week was the best time to take initiative, anyways. Lawrence and Ferb were taking a trip back to England to visit their relatives. If Linda's reasons for fucking Ferb was anything like Candace's, then she would be left even more sexually frustrated in his absence.

Isabella and Phineas executed their plan in the afternoon. Linda was in the kitchen, sitting at the kitchen table when Isabella walked in. Linda was conveniently wearing a sundress today.

"Hey there, Mrs. Flynn!" Isabella said cheerfully, taking a seat opposite her. "Whatcha drinkin'?"

"Tea, Earl Grey." Linda answered. "Lawrence introduced me to it when I first met him, though... to be honest, it just tastes like hot water."

"Do you know where Phineas is?" Isabella asked.

"No idea. I haven't seen him since this morning." she replied, though as she said this, unbeknownst to her, Phineas slipped underneath the tablecloth as she took another sip of the tea. The mere thought of what he was about to do made Phineas' dick hard as a diamond.

"Do you mind if I wait here for him?"

"Not at all." Linda replied. That was pretty much a greenlight for Phineas to execute his plan. He reached up underneath Linda's sundress and prodded his index and middle fingers against her panty-clad slit.

"AH!" she gasped, jumping enough that the chair slid an inch underneath her across the tile.

"Is everything alright?" Isabella asked in a faux-innocent tone.

"Y-yes." Linda lied, even as Phineas' fingers probed at her pussy lips. She knew it was Phineas, even without looking; it could not have been anyone else. She immediately regretted wearing a thong, much less one that was so tiny.

Phineas pulled her thong down her legs, then spread her legs even further apart. Linda's breathing quickened as she felt Phineas' fingers slip between her fleshy folds.

"Actually, I wanted to tell you something, since we're just sitting here." Isabella said.

"What is it?" Linda said with as calm a tone as she could muster.

"I'm in love with Phineas!"

"I... I see."

"We've already dated, and made out. We've even had sex. Like, a lot."

"I duh... I don't need to hear that." Linda protested, though a voice in the back of her mind was urging Isabella to continue.

"Oh really? You don't want to hear about how Phineas has ripped my clothes off and ridden me like a beast of legend?" Isabella purred.

"N-no, I do not!" 'God, yes, I do!'

"He must have gotten that big dick of his from his dad. It's so big I can feel it pushing out against my stomach, and every time he thrusts his full length into me, I can feel it ramming against my cervix!"

"Thasnice." Linda said through gritted teeth. Phineas was teasing her clit, and to her surprise, she actually spread her legs slightly further apart.

"And when he cums... oh my god, it's like a geyser of hot pudding into me!" Isabella blushed heavily and hid her face in her hands. Her eyes glazed over as she couldn't help but fantasize about the experience.

Linda said nothing about this. She closed her eyes and tried to control her breathing. Any effort she mustered to resist Phineas began to immediately crack, however, when she felt his pointed nose press against her pubis, and the rough texture of his tongue scrape against her labia and clit.

"Fffffhhhhhh!" Linda moaned, biting her lower lip.

"I know! I just lose it when I'm getting his cock so deep into my young cunny!" Isabella stood up and reached under her dress. She wasn't wearing panties currently; she wouldn't need them in a little bit, anyways. Isabella dipped two fingers into her moistening pussy and slid them up and down along either side of her clit.

"Mmmn, yeah! Just like this!" Isabella moaned. She doubled over onto the table and bounced her hips into her fingers as she thrust them deep into her preteen pussy. Linda looked on with arousal and fascination. She didn't lose her virginity well until she was eighteen. Seeing a young ten year old masturbate right in front of her and moaning with more genuine enthusiasm than any professional porn actress was uniquely invigorating.

"Unnhh! Unnhh! UNNHH! Yes, fuck me harder, Phineas!" Isabella cried out. She stared up at Linda, a sex-crazed look in her eyes. "He's grinding his fat head into my G-spot! It's making my mind go fuzzy and dizzy!"

Linda couldn't help but imagine herself in Isabella's position in her fantasy, getting taken from behind by Phineas. She already figured out that the two of them were in on this scheme together, but she couldn't bring herself to actually confronting them about it due to conflicting feelings. Lawrence's uptight British upbringing must have rubbed off on her too much. Still, their combined efforts were tearing down her defenses. Linda could feel a powerful orgasm flaring up inside her. How she longed to feel a powerful dick violating her insides again...

Isabella continued going, moaning louder and louder until she finally climaxed. She thrashed around on the table, eyes rolled in the back of her head. For a few seconds after coming down from her orgasmic high, Isabella lay there with her top half doubled over on the table, trembling. Then she got up and came over to Linda.

"I'm sorry, I just get so excited thinking about Phineas' cock." she cooed. "Do you like the idea, too?"

"I d-don't know what you're talking about." Linda panted. Her face was flushed a bright red.

"I bet you do. I bet you think about your son's dick all the time." Isabella pulled her smartphone out of her pocket and opened up a copy of the incriminating video that Phineas sent to her. "How else can you explain this?"

"Uuhh! Huuuuhhh!" Linda moaned in the video. Her body was glistening with sweat as she bounced up and down on Ferb's fat cock. "Good boy, Ferb! Your dick is pleasing mommy so much!"

Linda was so surprised by the existence of the video, let alone the content, that her concentration was broken. She did not realize how much she was resisting her orgasm. As soon as she lost concentration, it was like getting struck by a wall of lightning. Linda convulsed in the chair, her head thrown back and her feet stamping the ground on either side of Phineas. He sputtered between her legs as he suddenly got splashed in the face by a torrent of his mother's ejaculate. She had a sweet, musky scent that smelled like heaven to Phineas. He licked the pussy juices off his lips.

"It's kind of sweet that you'd fuck your own boy like that, but why leave Phineas out of the fun?" Isabella asked.

"Iahh... I don't know." Linda answered, though that answer didn't sound very convincing.

"Maybe you should give it a try? If not... we could just send it to Mr. Fletcher, see what he thinks about all this."

Linda let out a stressful groan. She scooted the chair back and stood up on wobbly legs. Her eyes welled up with tears from the stress.

"What do you want from me?" she growled, looking down at both Isabella and Phineas, the latter of whom was still kneeling under the table. His fly was open, and his surprisingly large dick was in his hand.

"Let Phineas fuck you like you do to little Ferb." Isabella cooed, pulling the straps of the sundress down so it piled up around Linda's ankles. She wasn't wearing a bra underneath, and the white thong was slightly askew, revealing her slobbering wet pink pussy lips.

"Fffhhh... fine." Linda said through gritted teeth. "Let's... go upstairs."

Phineas crawled out from underneath the table, and he and Isabella were led up the stairs by Linda, whose bare ass swayed from side to side despite her attempts to walk as stiffly as possible.

As they passed by Phineas' room, Isabella quickly ducked inside to retrieve the item she and Phineas discussed using once they managed to break through Linda's inhibitions.

"Get on the floor in front of the bed." Phineas ordered, pointing to a spot on the floor next to the large king-sized bed in her room. Neither of them mentioned Isabella's absence; Phineas' attention was too focused on his mother at the moment. Phineas hopped up on the bed after throwing off his shirt and stepping out of his pants.

"Why do you want to fuck your own mother?" Linda asked as she got down on her knees in front of him.

"Why do you fuck your own son?" Phineas asked.

"Stepson." Linda corrected spitefully.

"Does it matter? He's not much older than me. Does dad not do it for you?"

She responded with an icy stare from under her brow.

"Well don't worry, dear mother. I'll make sure you're begging for it by the end." Phineas grinned, though he couldn't help but feel a twinge of nervousness. While this was his plan in the first place, it almost felt like a dream, being here, about to fuck his own mother.

Linda reluctantly lowered herself between Phineas' legs and cupped his massive dick between her breasts. It was the first time he received a boob job. It never occurred to him before then, since, aside from Candace the other day, he never had sex with anyone but Isabella, who was flatter than an ironing board. He could have kicked himself for not thinking about it before. Boobs were incredibly soft and squishy like a marshmallow, and they felt even better around his dick.

"So this is what you wanted?" Linda asked, rolling her breasts up and down the length of his dick.

"Hnnnhhh, y-yes." Phineas answered. "Though I imagined you'd suck it a little bit, too."

"Luh... like this?" Linda planted her breasts in his lap and licked the underside of his dick. Phineas shuddered and involuntarily thrust his hips upwards, pushing the tip of his cock into her mouth.

"Mmmnn! Mmn..." Linda gasped and hummed as the dick forced its way inside her mouth. She dipped her head down a few inches. Her tongue flicked along the bottom of the shaft. Phineas felt like his dick was trying to burst out of its skin to get even more erect. The suction Linda created with her mouth was even more powerful than Isabella's. He gripped the mattress sheets and writhed around underneath her. This was a lot more intense than he imagined it would be, and he began to legitimately worry that he was not going to last long enough to satisfy her before he came.

"I see you've already started without me." a voice said behind them. Isabella entered the room, completely naked and carrying a black leather double-sided strap-on and a bottle of lube. The dildo was a deep royal purple and nearly as thick as Isabella's forearm, and studded all along both lengths.

"Mom won't notice that I borrowed this." Isabella said coyly. She set up shop next to the two, applying a generous amount of lube to both ends. Once she was finished, she pushed one end of the dildo into herself and fastened the straps around her waist. The dildo was angled at the end to push up against just behind her G-spot.

Isabella doubled over on the bed and took a moment to catch her breath. The dildo was so large inside her. It was, after all, her mom's toy, and from some snooping around, Vivian was apparently into a lot of sizeplay, so the dildo was much bigger than normal. The slightest movements Isabella made jostled it around inside her. The end, like a hooked finger, stimulated the spot between her G-spot and cervix. It was making her dizzy and causing her abdominal muscles to quiver.

Gingerly, Isabella moved behind Linda as she continued to suck off Phineas. She placed her hands on Linda's ass. The cheeks were warm, round, and surprisingly firm. Her overall body type was a far cry different from Vivian's, who was short, but quite shapely. She pulled the tiny white thong down her legs and off her feet. She was soaking wet down there; her pussy juices were drenched in the thong. Isabella tossed it aside and pushed her hips forward, guiding the tip of the dildo with one hand to Linda's plump entrance.

She popped the head in past the labia and teased Linda by pumping it in and out a few times. Isabella could feel her tremble through the dildo, and her clenching vaginal muscles pulled her further in a solid inch. She suddenly rammed the full length into Linda's pussy.

"Mmpphh!" Linda moaned through Phineas' dick, her eyes widening as she felt the dildo come to rest just short of her cervix.

"Sorry, Mrs. Flynn." Isabella said with mock sincerity as she started pumping the dildo in and out of Linda. Even though every inch of the shaft was lubricated, she was surprised just how much effort she had to exert to pull out of her. Linda's vaginal muscles clenched around the shaft with a vicelike grip. Isabella quickly gained a whole new respect for boys as she realized just how exhausting it was to thrust with your hips instead of with your legs.

'I can't believe I'm getting raped by a child... and my own son, at that.' Linda thought.

"I wonder how much you'd be able to take in all at once." Phineas mused. He placed his hands on Linda's head and ran his fingers through her hair. He angled himself so he could push smoothly into her throat, then slowly pushed his hips forward.

"Ohh, wow..." Phineas gasped as his mom inched her way down his shaft. He could feel the head brush past her fleshy uvula in the back of her throat, then slowly slip down her throat. Not even Isabella did this with him; she was not experienced enough to do it. The feeling of her throat expanding and contracting with every breath she took through her nostrils was exhilirating. Phineas could also feel the rough texture of her tongue lapping at the base of the underside of his cock, right where it met his taut round balls.

'There is no way she could fit my balls in her mouth.' Phineas thought. 'She's already at her limit.'

To his immense surprise, however, Linda managed to get her tongue underneath his balls and scoop them into her mouth. He winced and moaned out loud as she juggled them back and forth on her tongue. Her moans from Isabella's treatment reverberated through his immense shaft. He was actually trembling from the stimulation! Phineas fell back on the bed, his legs quivering, as Linda sucked him off. A powerful tingling sensation went from his balls to the very tip of his dick, buried somewhere halfway down Linda's throat.

Linda was surprised she was getting so much into this. She should have been much angier, but that was starting to fade away as she started to feel very good from Isabella's treatment.

"Ggghruguuhh!" Phineas gurgled his words as his orgasm built up far faster than he was able to control. He moaned loudly as he came suddenly, thrashing about underneath Linda and blowing his load directly into her stomach. Linda didn't have to swallow, as he was so far down her throat, so she instead focused on stimulating his balls even more to keep him at the very height of his orgasm as possible. Phineas moaned like a cow in the throes of birth, wrapping his legs around the back of Linda's head and humping into her face.

Linda could feel his cock slowly beginning to soften inside her mouth until he was roughly at half-chub. It wasn't until he stopped humping her face and was reduced to feeble spasms did she finally release him from her throat. Her mouth and throat felt strangely numb, as did her pussy, and she was strangely lightheaded. It was then she realized with delight that she had had her first throatgasm in a very long time.

Of course, two orgasms wasn't going to be enough for her. Linda had a diesel-powered sex drive, and the only thing Phineas and Isabella managed to do so far was start her engine. Isabella pulled away from her as Linda stumbled to her feet and climbed onto the bed next to Phineas. She didn't care if she was getting fucked by her own son, she needed sweet release.

• * *

Candace was in her room when she heard what sounded like a wildebeest getting forced through the mouth of a tuba. At first, she thought it was something outside, but as she perked her ears up for anything else that might follow suit, she heard something coming from elsewhere in the house. It was probably just Phineas up to his usual antics. She was not keen on the idea of telling him to quiet down. He'd probably just rape her again or threaten her with that goddamn video.

As she returned to her bed, however, she heard the high-pitched squeals of a young girl. This gave her pause. Was there someone else in the house? Did Phineas have a girl over?

"Probably Isabella." Candace muttered to herself. It took her a moment to fully register the situation, and the opportunity at hand for her. If that was the case, and Phineas and Isabella were having sex in the house, she could possibly get back at him by recording video of that like he did to her, and then hold THAT over his head until he got rid of the video he was holding over her head.

Candace snuck out of her room and instinctively crept over to Phineas' room, but before she could peek inside, she realized that the sounds weren't coming from his room. They were coming from further down the hall.

"Mom and dad's room?" she asked. They were probably shagging on their parents' bed, because that was apparently a thing kids liked to do. Stacy admitted she did that once with Chad. This was even more in her favor. She could only imagine the kind of trouble they'd be in with mom.

As she opened the door, however, Candace realized her plans were shot clean out of the sky. Inside Linda's room, she was on her knees as Phineas and Isabella fucked her in her pussy and ass, respectively. There was a look of genuine pleasure on Linda's face as both tiny bodies slammed into hers.

"MMnn, I cuh-can't believe my own son is fuh-fucking me like this!" Linda gasped. She was surprised to find just how perfectly Phineas' dick fit inside her. It curved in just the right way that every time he drew back, the bulbous head would grind against her sensitive G-spot. If that wasn't enough, the combination of it and Isabella plowing her in the ass created one of the most intensely orgasmic sensations.

"Hee hee hee!" Isabella giggled like a drunk, a heavy blush and grin plastered on her face. She had her arms wrapped around Linda, her hands groping at her large breasts as she slammed her hips into her ass. The cheeks cushioned the impact, and there was something pleasing about slapping her body into them, besides. The other end of the dildo jostled around inside Isabella's pussy. She came once already, but because she did not allow herself to come down from that high, the endorphin rush started to mess with her capacity for higher thought at the moment, and reduced her to a drooling, giggling mess.

It took Candace a moment to register exactly what she was seeing. Once her brain started processing all the available information, she was able to put two and two together quite quickly. They must have blackmailed Linda with the same video. That thought made Candace's blood boil. Did Phineas intend on holding it over their heads forever?

Candace didn't know what she was going to be able to accomplish with this, but she took out her smartphone and started recording the events unfolding before her. Her heart was racing the whole time, and she started to feel a little hot under the collar.

The three were so busy with each other and were not aware of Candace's presence at the door besides, so she figured it was okay to strip down a bit. Trying to carefully hold the phone steady, she unbuttoned her shirt and tossed it to the side, followed by her skirt, leaving her just in her socks and panties. Yet the heat didn't seem to go away; if anything, it got a lot worse.

"HHUUUNNNHH! Keep going, Phineas!" Linda cried out. "Mommy's gonna cum again!"

"Suh, so am I, mom!" Phineas panted, though whether or not she actually heard that was unclear. He closed his mouth around one of her nipples and sucked on it as he continued to fuck her.

Candace found herself longing to have her tits sucked again. As much as she hated to admit it, she did actually enjoy it when Phineas played with her breasts. She subconsiously moved a hand up and cupped one of her breasts. As a finger rolled over the nipple, she gasped and shuddered violently. Her nipples were so sensitive to the touch that she could actually feel the rough texture on her fingertips. Her clit throbbed painfully in her panties, and actually erected enough to rub against her panties.

"Fhhh... fuck..." she muttered to herself. Without thinking, she set the smartphone down on the ground and wiggled out of her panties. She wasn't thinking about the recording anymore; the sight of her mother getting double-teamed by Phineas and Isabella really turned her on.

"FNHH! HUUHH! UUUUHH!" Linda moaned heavily as she experienced a powerful double orgasm. She wrapped her arms around Phineas and held him close. Her entire body was quivering from the climax, and she wobbled dangerously, threatening to lose her balance and topple to the side.

Candace dipped her fingers into her slit as she watched. She couldn't help but feel immensely jealous of her mom. She heard from some of her friends just how incredible it was to get fucked in your pussy and ass at the same time. She never had a chance to experience it yet, but by the look on her mom's face, their claims were no exaggeration.

Isabella slumped up against Linda's back as she hit her orgasm. Her eyes were flickering and rolled the back of her head. She was so subsumed in endorphins that she didn't notice that her orgasm was building up again until it exploded throughout her body.

Linda couldn't kneel upright any longer, and she fell to her side. Isabella pulled out of her ass and climbed off the bed, and Linda took the opportunity to lay down on her back. Phineas lay on top of her, continuing to fuck his mom.

"Nnhh! Nhhh! HAAHHH!" Phineas grunted. He threw his dick into her very aggressively for several more thrusts before tensing up. Candace could imagine that he was cumming into their mother. It was an arousing sight to behold, much more, in her opinion, than to experience it herself.

Isabella unbuckled the strap-on and pulled it down her legs with some effort. She trembled as the massive dildo slipped out of her, which nearly caused her to cum again. Candace's eyes widened when she saw just how big it was, and she had to wonder how a ten year old could fit a dildo that large inside of them. She finger fucked herself even more vigorously, thinking about being ten years old again and having that dildo inside of her.

Isabella climbed back onto the bed and sat down on Linda's face, straddling her face with her knees. Linda knew what was expected of her, and she opened her mouth to cup around Isabella's pussy right as she settled down on top of her.

"Mhhmmmhhh!" Isabella giggled. Linda's tongue flicked against her soaking wet entrance. The rough texture felt amazing on her clit. She braced herself with her hands on the mattress and tried to hold her hips steady as Linda ate her out.

Candace could feel her own orgasm building up with incredible speed. She wanted to be in the room, too, getting fucked by Phineas while she lapped at Isabella's pussy like a dog thirsting for a drink. Standing up at the moment, however, was out of the question, as she was so determined to hit her climax she was curled up in a ball on her back, tugging at her clit and stabbing her puffy labia with her index and middle fingers. Her face was red from the concentration. Getting past that last hump into the realm of utter bliss was like trying to push a boulder up a hill.

Her efforts finally paid off as she unfurled and bent in the opposite direction, bending her spine backwards and thrusting her hips up into the air. Candace's vision exploded in a shower of colorful lights, and she spasmed on the ground in the throes of a powerful orgasm. In a minimalistic effort to keep her voice down, she made a series of hushed gasps and squeaks.

The three inside the room were so occupied with each other, they didn't give an ounce of notice to Candace cumming just past the slightly ajar door. Isabella was staring down at Linda with a perverse look on her face. Her hips squirmed about as Linda's tongue drilled deep into her. It was her first time recieving oral; Phineas preferred to assault her pussy with his cock.

"Mmnn, keep licking me!" Isabella squealed. "I'm guh... gonna cum! HAAAAAIIIIIHHHH!!"

Linda sputtered underneath her as Isabella squirted into her mouth when she came. It was then she discovered that Isabella was a gusher, and she had to quickly swallow the girl cum to avoid drowning in them.

Phineas, meanwhile, lay on top of Linda's stomach, his dick still buried balls deep inside her pussy, as he recovered from his powerful orgasm. The most he did during this time was grind into his mom and keep his dick erect.

"Mmhh! You are so good at eating pussy!" Isabella panted, crawling off of Linda's face.

"Uhmm..." came Candace's shaky, awkward voice from the doorway. All three of them looked up at her. Her legs were trembling as she entered the room. She discarded her panties in the threshold, and her smartphone lay forgotten in the hall. "C-can I join you?"

"Hee, sure thing!" Isabella said, hopping off the bed. "Phineas is busy with your mom at the moment, but I'll entertain you until it's your turn!"

Candace smiled, and she and Isabella moved over to an empty spot on the bed. Phineas gathered together his energy, and he sat up, repositioning himself so he straddled one of Linda's thick thighs with her other leg slung over his shoulder, and he began fucking her again.

"Hnnnhh! This feels so good!" Linda gasped. "And your cum feels so hot inside me!"

"That's good, because I'm gonna cum inside you again until you get pregnant!" Phineas growled as he slammed his hips into hers over and over again. "I've thrown away your birth control pills, too, and don't think about getting more of them, or I'll send that video to dad!"

His mom and sister should have been more distressed and angry at him upon hearing this, but they craved sex too much at the moment to put up a protest. Isabella and Candace decided to follow in Phineas and Linda's stead and interlocked their legs so their pussies touched. Candace's pussy was like the mouth of a lit oven. Her erect clit clashed against Isabella's as they rolled their hips around.

"Fhhuhhh... fhuuhhh... fuuhhhh!" Phineas grunted through gritted teeth as he fucked Linda. His balls tingled with the familiar electric sensation of a building climax, and his thrusts were so vigorous, they slapped against Linda's thighs with regularity.

Phineas repositioned the two of them so he was leaning over Linda with her butt lifted up in the air, her lower half supported by the balls of her feet. Phineas' dick rubbed against the roof of her love canal due to this new exotic angle, almost stabbing directly onto her G-spot.

"Hhhnnhgg! Your dick is making me feel so good!" Linda encouraged. "Keep fucking me, Phineas!"

Isabella and Candace both tensed up as they came together. They drenched each others' pelvises in their sweet love juices.

"Haaaahnnhh!" Isabella squealed with delight. "Phineas told me you were a gusher, just like me! This is amazing!"

The two girls went limp as their orgasms died down. Isabella's body beaded with sweat, but Candace had barely begun to exert herself, so her heart rate and breathing were only slightly higher than normal.

"Hhhnnnhhh! Oh, yeah!" Phineas gasped. "I'm gonna cum again!"

"Huh! Huh! Huh! Do it, Phineas!" Linda panted. "Cum deep inside me!"

Phineas slammed his hips into Linda one last time before he flew over the edge. His dick twitched violently as it spurted out even more ropes of hot semen into his mom's quivering pussy. Just like what happened with his first time with Candace, it felt like his was being spurred on to shoot even more cum into Linda than he would have otherwise with Isabella.

Phineas pulled out of Linda even as he was still ejaculating, so the last spurt or two coated her wet, hot pink labia. Linda lowered her legs on either side of Phineas and relaxed on the bed, gasping for breath. After multiple orgasms, she had finally reached her limit. Her pussy and abdomen tingled from the repeated rush of endorphins.

Phineas took a moment to catch his breath, then he turned his attention to Isabella and Candace.

"Okay... now that mom has had her fill, now it's your turn." He said. Candace nodded her head nervously. She knew this moment was coming, and as much as she loathed the idea of getting fucked by her own brother, she needed to feel his dick inside her again. Phineas crawled over to her and lay down on top of her, angling himself so he would push smoothly into her pussy. Without actually meaning to, Candace wrapped her legs around Phineas and held him close as he fucked her. Isabella climbed off the bed and grabbed the strap-on off the ground before heading into the bathroom to clean it off.

"Hmm hmm, it's so nice to see my son and daughter playing together." Linda cooed, sliding over to them and coming to rest right next to Candace. "Though Phineas shouldn't be doing all the work, Candace. Have you ever ridden a cock before?"

Candace shook her head. Now that she thought about it, she was always on bottom whenever she had sex in the past.

"Here, you should flip over and just... sit down on him, like that." Linda helped Candace roll over, holding Phineas inside of her as she did so, so that he was laying on his back, head resting on the pillow and Candace was sitting on his lap, most of her weight put on her knees on either side of him.

"Good girl. Now try this position." she said. Candace nodded and moved her legs around slightly to lower her body onto the cock, then lift herself off of it. It was a great deal different than just laying underneath and letting the man do all the work. It required her to use leg muscles she didn't even know she had, but as the pleasure started to build up in her body again, her sex drive began to override the burn she began to feel in her inner thighs.

"Oooh, perfect position for me to squeeze in." Isabella said from the bathroom. She emerged, wearing the strap-on again and walking awkwardly due to the thick shaft stretching out her insides. The strap-on had been cleaned and treated with a fresh coat of lube. She climbed back up onto the bed, stumbling for a moment as the dildo rubbed against her sensitive vaginal walls and sent a jolt of pleasure up her body. She inched up behind Candace and wrapped her arms around her front. Knowing Candace's great weakness, she brushed the tips of her middle fingers against the extremely sensitive nipples.

"Hnnhhh!" Candace squealed through gritted teeth. Isabella, with Linda's guidance, pushed her hips between Candace's butt cheecks so the dildo woudl slip into her asshole.

The feeling of being double penetrated was immediately noticably different to Candace. She never got fucked in the ass before, so she didn't know how good it felt on its own, but the euphoric sensation in her pussy seemed to be magnified several fold, and the feeling in her ass along with it.

"Hu hu, it feels good, doesn't it?" Linda asked, slapping Isabella across the ass so she would jostle around inside Candace. "Once you've been double teamed, it's so difficult to want to go back to anything else!"

Isabella started pounding into Candace with renewed vigor. Candace tried to continue bouncing on Phineas' dick, but the pleasure was too much for her to bear, and she doubled over Phineas, bracing herself against the bed by her arms, too drained of her strength to move. Isabella's fingers continued to roll over her nipples. As it turned out, not only did her vaginal muscles clench up in response, but the muscles in her ass as well.

Isabella suddenly picked up the pace, thrusting into Candace's ass with incredible vigor. She'd pull all the way back until only an inch was inside Candace, then push back in with as much force as her little body could manage. Her hips were starting to ache and the bliss in her pubic region was almost overwhelming, but she steeled herself and refused to break her pace. The force was enough to push Candace back and forth along Phineas' dick. From his position, he could see her depraved smile and her clouded-over eyes. She was in heaven already, and she had yet to hit her climax.

Candace all but blacked out when she came. The sphincter muscle and a little of the surrounding flesh, her pussy, and her nipples all went numb, and a warm bliss washed over her like a tsunami. All awareness of her surroundings faded, even her sense of identity, and she floated in an abyss of unmitigated joy and pleasure. The warmth seemed to radiate out from her body. She was like a sun bathing her own inner world in heat and light. There was no greater harmony.

Linda held up Candace as she spasmed. A second later and she would have fallen right on top of Phineas. Isabella pulled out and plopped down on the foot of the mattress. Her abdominal muscles were still quivering like crazy, and she was so dizzy from the experience, she could barely maintain her balance.

"Here, let's roll her over. Then you can finish inside her, Phineas." Linda said. She helped her two children roll over so Candace was bottom and laying back on the bed. She was still unconscious, twitching underneath him like she was having a seizure. Phineas hiked her legs up around his waist and fucked her. The tip of his dick was heating up. Her vaginal muscles were calming down, though she still contracted around his cock every few seconds.

Phineas came pretty quickly, since he was already warmed up. He pulled himself as deeply into Candace as he could manage, the tip of his cock pressing against the entrance to her cervix. His seed splashed against the bulbous opening. With how many times he came inside her lately, at least one of them had to impregnate her.

"It's so nice to see my son and daughter playing so nicely together." Linda cooed, massaging Candace's stomach as Phineas pulled out of her. She cuddled up with her daughter and gave her a tender kiss on the cheek.

"I'm going to go get a drink now." Phineas announced as he hopped off the bed and made his way out of the bedroom. His movement was a bit wobbly from the fatigue from one orgasm after another. He managed to make his way downstairs to the kitchen. He poured himself a glass of water and was halfway through it when Isabella came down the stairs. She was completely naked, having abandoned the strap-on back in the bedroom. She was holding her and Phineas' smartphones in her hands.

"Hey, Phineas. That went better than I expected." she said.

"Yeah, no kidding. I thoguht they'd put up more of a struggle." Phineas replied.

"Did you want to do that thing now? I have the video right here."

"Gimme. I want to see what I'm working with." Isabella handed Phineas the smartphone, where it was paused at 0:00, the camera pointed at an empty bed that he didn't recognize. Phineas hit the play button, and watched as Gretchen from Isabella's Fireside Girls troop entered the frame. She was naked and leading a naked man across the length of the frame and guided him onto the bed. Phineas immediately recognized the man as his stepfather Lawrence.

Lawrence laid down on the bed so Phineas could only see his legs and cock, but the first few seconds identified him easily. Gretchen climbed on top of him, her legs straddling his chest behind her and her face level with his erect cock.

"Yeah, this'll be perfect." Phineas described. He fast forwarded through the rest of the video. Gretchen began by sucking him off, throating as much of it as she could before sitting up and guiding it to her small, tight pussy lips. Lawrence was quite a bit bigger than Phineas thought he would be, and he had to wonder how exactly he managed to fit inside Gretchen, who was quite small even for a ten year old.

The rest of the video went on for about fifteen minutes longer and mostly composed of Gretchen bouncing around on Lawrence's dick, occassionally changing positions. It ended with Lawrence sitting up and holding her tightly from behind as he came deep into her young womb. By that point, Gretchen's glasses were askew and fogged over.

Phineas closed the video and sent it to his own smartphone, then contacted Lawrence from it.

Phineas: Hey, dad.

Lawrence: What's up, Phineas?

Phineas: Oh nothing. Just found an interesting video that you might want to take a look at.

Phineas sent Lawrence the video. There was a long pause on the other end; Phineas could only imagine the mortification Lawrence must have felt when he saw the video.

Lawrence: Where did you get this?

Phineas: That's not really important right now, is it?

Lawrence: Does anyone else know about this video?

Phineas: Not yet, and if you want it to remain that way, you will not come back to Danville.

Lawrence: What?!

Phineas: I think it's time to split the family back up. It's better this way, for all of us.

Lawrence: You can't do this to us, Phineas.

Phineas: I can, actually. Or else I can just send this video to the police...

Lawrence: Fine. Fine. What about our stuff?

Phineas: Oh don't worry. We'll ship it to you. Maybe. Goodbye, "dad".

Phineas closed the messenger. So that was it. Lawrence and Ferb were out of the way. It felt like a chain was removed from around his neck.

"Good." he said to himself. "Now to impregnate those whores Linda and Candace."

One afternoon the following week, Phineas was in the living room fucking Isabella when Candace and Linda came into the room, each bearing a pregnancy test that came out positive.
