I'm in between my freshman and sophomore year in college, and home for the summer at my Mom's and Stepdad's house. Last week my stepbrother Jaime who is in high school came to stay the week. Our bedrooms are separated by a bath with doors to each room. Jaime is 15, a cute athletic kid with a nice personality.

Monday morning I got up and went into the bathroom, and the door to Jaime's room was open. When I went to close it, I saw him sprawled out asleep on his bed, wearing only his boxers, with his hard dick poking out through the slit. I quickly closed the door to just ajar, and stared at his body. His smooth athletic chest slowly expanded and collapsed as he breathed, his abs were hard and tanned, and a small trail of hair ran down from his navel into his boxers. His dick was long and white, and curved upward. It would occasionally twitch, and I felt myself start to get wet. I quietly shut the door, jumped into the shower. I closed my eyes, and fantasized about Jaime while I slowly fingered myself. I took the shower head off its holder, changed it to pulsate and ran it over my clit. I could feel my orgasm start to build, and looked down at my pussy. Suddenly I saw Jaimie through the shower door watching me. I dropped the shower head, covered myself and turned away with a shriek. Jaime stammered out an apology and left.

I quickly got out of the shower, got changed and went to the kitchen. Jaime was having a bowl of cereal, and appeared to be as embarrassed as I was. I quickly grabbed some juice and headed for the family room. Thankfully, my Mom soon came in, and we talked. She finished up, and left for work, again leaving Jaime and me alone. Jaime came into the family room, and started apologizing profusely, saying he didn't know I was in the bathroom, and he was sorry. He kept rambling on, saying it was a mistake, he wasn't a pervert, and begging me to forgive him.

He sat there and ended with pleading for anything he could do to make it up to me, and to please not tell my Mom, as he knew his Dad would kill him for watching me in the shower. While the shock of seeing him in the bathroom had killed the moment for me, I still hadn't gotten off, and still was a tad horny. So I quietly said to him that to make things even, I should be able to watch him masturbate. His jaw dropped, and he became fidgety, and said c'mon be serious. I said I was serious, so go ahead and whip it out. Slowly he pulled his shorts off, revealing a nice soft dick, and a low hanging set of balls. I moved over to the couch next to him and watched. He started to play with himself, his eyes averting me. After a couple of minutes, he still wasn't hard though, and he said he couldn't do it, he was too nervous.

I reached over and wrapped my fist around him and slowly pulled it. He started hardening up quickly, and soon I was jerking his dick, and he leaned his head over the back of the sofa with his eyes closed. I cupped his balls in my left hand, and kept slowly jerking him off, while rubbing his nuts. He moaned a little, and I could see clear precum on the head on his dick. I touched it with my index finger and swirled it around the head, and he squirmed more. I went back to jerking him off, and he started telling me to go faster, and was thrusting his hips into my fist. Suddenly his whole body tensed up and froze, and three big jets of cum shot out onto his t-shirt. It was so fucking hot. I went to the kitchen got some paper towels and came back and cleaned him up. There was cum everywhere. He smiled at me and thanked me. I told him the whole thing had made me incredibly wet, and would he mind getting me off.

I took my shorts and panties off, and he reached over and started fingering me roughly. I grabbed his hand, and asked him if he had ever done this before with a girl, and he said no. So I showed him how I like it, by circling my clit and running a finger down between my labia. He was a quick learner, because soon he had found the right pressure and pace on my clit, and I was writhing to the pleasure. I lifted up my shirt and played with my nipples as he kept it up. He leaned over and starting sucking my nipple, and it sent me over the top. My pussy gushed and I had a lights out incredible orgasm.

We couldn't keep our hands off each other the rest of the day, and had three more orgasms each. The rest of the week we masturbated each other every day after the P's headed to work.

I can't wait for Jaime to come back in 2 weeks!
