I Felt Bad

My sister recently had a sleepover with our neighbor and another girlfriend. Her neighbor invited her boyfriend and his brother to even things out I guess. Funny thing is I’ve been knowing her for a while now and she swears like a sailor. We have been messing with each other and it never stopped. She’s very touchy, and I tend to be the same with her. I’ll jokingly slap her ass and pull her hair. I would be lying if I said I never thought of her sexually because she looks hot for a sixteen year old. Anyways we were all watching a movie in our theatre room and somehow no one noticed her feet touching my thigh. She eventually started touching my crotch and her boyfriend was oblivious. The girls went upstairs and the boys played games for a bit before falling asleep. As soon as they were snoring I went upstairs and got in a quickie with her. She also sucked me in the girls room.
