Would you let it happen?
So I've read and heard stories about little sisters practicing oral sex on their older brothers. In fact I also knew a girl, who told me when we were talking about oral sex, that her first one was with her older brother. She said it was the best practice she could ever get, and that she didn't want to do it with a complete stranger because she was really self conscious.
Now guys out there, would you let your sister practice giving blowjobs on you, if such ever occurred?
