That my sister did this to me.
I recently required stitches on my back. I live alone so I would stop by my parents house so they could help me clean it and bandage it. They weren't home so I got my sister to do it. She's 25 and never had a boyfriend so I assume she's a virgin. As she was putting cream on it I felt her had pull my zipper down and started rubbing my cock. She did it without any warning at all. I didn't stop her. She eventually pulled my pants Down and started stroking it until I was hard. It felt so good but then she stopped and said your bandage is done and your cock is so big. She just walked away and I just left. Now I want her. What do I do?
