Horniness takes over, you pull down "your sister's" pants and jump at her boyfriend. He falls down on the couch, while you are in the right position to feel his erecting dick pressing against your sister's flat crotch. You don't know if this was the right decission and how far your sister wanted to go, but her boyfriend likes it and grabs her butt. Despite the heat and desire you feel comming up in your crotch, you sense a "strong" hand grabbing your butt. Honestly, you were not expecting him to have such a strong grip, but maybe it just feels that way because you are a girl now.
