Chapter 1: Ethan

Our mom works a lot. That's basically the short version. She's a nurse at a big hospital, and ever since my little sister, Lilly, started school, she's left me to take care of her. You see, our dad, Thomas, died when Lilly was really little. She doesn't remember him, but I do.

Ever since the car wreck, our mom, Katherine, has worked really hard so that we can still live in the same city. I don't think it's such a big deal, but she told me she doesn't want me to have to change schools and make new friends somewhere else.

I know it was really hard for her for a while, but when she got a promotion she was able to afford it a little easier. The only bad thing about her promotion is that she always works at night. She goes to work around the same time I get out of school and then I'm the only one there when Lilly gets home. At first I thought it really sucked because I couldn't have any friends over, or go out with anyone after school. But now, I actually look forward to taking care of my little sister.

I was 12 when it started. I don't think most adults would think I was old enough to care of my little sister all the time, but our mom said I was very mature and was old enough to handle it. Lilly had just started kindergarten. It was pretty easy, really. I just had to make sure that we both ate and sometimes I would play with her when she was bored. Mom bought us a new game system when she got her promotion, so we would play games together.

Since I got out of school earlier, I was already at home when the school bus dropped her off and had usually finished my homework by then. She would usually want an after school snack and then we would both do our own thing for a while unless we both wanted to play video games. Sometimes we would get into arguments, but we didn't usually. We were a lot friendlier than my best friend and his sister. They fought all the time.

I would microwave dinner when we got hungry and then before Lilly's bedtime, I would make sure she had a bath. Not every day, of course, but at least a few times a week. Then I made sure she got dressed for bed and I tucked her in. I liked having a few extra hours to myself once she was asleep. Then by the time our mother got home early in the morning, I was already in bed, too.

Things went on like this for several months, almost a year. But I remember the day it started to change like it was yesterday. It had been a rough day at school because a couple of kids had been mean to me—including a girl I thought I liked.

I didn't talk much that evening and was feeling kind of depressed as I leaned on the side of the bath tub while Lilly splashed and was showing me something. I don't remember what she was trying to show me, just some dumb little kid thing.

The only thing I remember seeing in that moment was her flat chest peering out of the water. For some reason, I just wanted to lean over the side of the tub and kiss her little nipples. I felt my cock move in my pants and I didn't really understand what was happening. In my head, I was stripping off my clothes and rubbing my self over her body.

What I was thinking seemed wrong, but it didn't feel wrong. Still, I restrained myself from climbing into the tub with her. However, I couldn't help but reach out and soaping her up. I'd done it a hundred times, after all, even before I was taking care of her all by myself.

She had no idea what I was feeling as I touched her flat chest. I guess I didn't really know either. I had been taught the basic principals of sex, but I didn't really understand what I was feeling that night. I probably didn't truly understand for a few weeks after that, either. All I knew was that I was starting to think that my 6 year old little sister was the most beautiful girl I had ever seen.

That night, I found myself thinking about her naked body after I had put her to bed. My cock grew hard again as I sat in my room. Without really understanding what I was doing, I started touching myself while I imagined giving my little sister a bath. Then I imagined her giving me a bath and rubbing me all over. My brain told me that it was gross and disgusting, but something else told me that it was the best sensation of my entire life. I continued until I had what I would later learn was my very first orgasm.

At first, I just kept giving her baths like usual, just taking a little more time to clean her up and enjoy the view. For a while I was scared to go too far with her baths, but I began getting bolder after a couple weeks went by. Then I started insisting that she take a bath every night, and when she asked why, I insisted that she just looked dirty. But then I started coming up with activities after school that we could play out in the yard or even at the park down the street. That way I could be sure she'd get dirty enough for another bath.

"I'm not THAT dirty!" Lilly said one night. I realized then that I had been rubbing up her chest with the bar of soap for several minutes.

"Oh, sorry," I replied, and moved on to shampooing her hair with my cock hard as a rock in my pants. That was the night that it happened.

I finished her bath like normal, drying her off and making sure she got dressed for bed. She usually just wore one of my t-shirts to bed. I had just barely started to wear an adult small, but they were still the length of a dress on her. After tucking her into bed, I went to my room and played games on my computer until it was time for me to get to sleep.

By that time, a big storm had rolled in. There was thunder and lightning and it was raining pretty hard. I was in bed, wearing a pair of boxers and thinking about Lilly in the bath. I was imagining that I was bathing with her, rubbing my cock over her flat chest. My hand went under my sheets and into my boxers, reaching for my erection. I was so lost in my fantasy, I didn't even see her come in.

"I'm scared," her voice made me jump.

"Ah!" I nearly jumped. "Did the storm wake you up?" Seeing her suddenly in front of me was everything. There was another loud clap of thunder.

"Can I sleep with you?" She didn't wait for an answer and climbed into my bed. As she settled in, I felt her leg rub against my hard cock. It was still inside of my boxers, so even if she had felt it, she probably didn't think anything of it. She looked up at me and I kissed her. It was a brotherly kiss against her cheek, but I probably held it there longer than normal.

"I love you, Ethan," she said.

"I love you, too," that's when my cock slipped out of the hole at the front of my boxers. With one arm wrapped behind her, I reached down to put it away. When I touched it, however, I began to finish myself off instead.

With Lilly laying next to me, it didn't take long. Her night shirt had ridden up, and I felt her panties against my hand. She didn't notice anything out of the ordinary right away. When I started squirting juice over her panties, though, she spoke up.

"Hey, what the!?" She looked underneath the covers. I moaned as I ejaculated more that I thought possible.

"Uh, sorry," I moaned again, leaning in to kiss her cheek again.

"Hey, I can see your weiner!" she replied, lifting the covers up to examin the odd goo that was dripping over her stomach in the dim light. "Ew is that pee!?" She could see the cum continuing to squirt out of my cock.

"No it's the stuff that makes babies," I managed to say as I started to come back to reality. "Oh my gosh, I'm so sorry, Lilly," I pannicked once I'd fully come back to my senses. "I didn't mean to. Please don't tell mom. Don't tell anyone, okay?"

I was freaking out, but she didn't understand what had just happened. She was too young to know how wrong it was. "There's iky stuff all over my panties," she replied. "It got on my shirt, too."

"Sorry, I'll go get you new panties. Oh, I'm so sorry," I kept apologizing. There was another loud clap of thunder and she jumped into my arms, freightened by the storm.

"It's okay!" I hugged her. "Let's go get you cleaned up." I carried her back to her room. My cum was getting on my chest, but it didn't bother me. In her room, I peeled off the night-shirt and pulled down her panties. I use the shirt to clean us both off and found her a fresh pair of panties.

"I'm sorry, it was just an accident," I apologized again.

"It's okay, Ethan," She said as I carried her back to my room. I didn't bother finding her a night shirt, and just put her back in my bed.

She wasn't that bothered after that first night. But then, I had only jerked off on her by accident, and she was too little to understand that there was anything really bad about it. But in the weeks that followed, she would start understanding a lot more about sex...
