Just after my step sister Jackie finished blowing my throbbing cock and spitting on it, she told me she’s an anal virgin. She thought it was embarrassing but figured she could tell me after all the time we’ve been spending together. I told her it wasn’t and she still had time to learn. She mentioned how since I’m her step brother she trusted me to help her. I didn’t really hold back and told her I could. I fucked a lot of girls in the ass and my step sister was the one girl I wanted to be inside of. I slowly slid my cock inside her tight asshole and fucked her pussy too. I fucked both of her holes I covered her in cum.
