I have a question regarding roleplaying. I've done teacher/student, father/daughter, neighbors, quarterback/cheerleader and so on. Recently saw a thread about sibling roleplaying and reminded me of one of the guys I used to hooked up with regularly.

He loved doind bro/sis roleplay and it's stuck in my head now. I want to big big brothers little sister and beg him to go ahead and knock me up. Have him say things like oh yea little sis I'm going to get you pregnant.

It's stuck in my head and I want to do this type of roleplay over and over and over. Any one else have something like this happen? Getting a roleplay scene stuck in your head and just wanting to do it repeatedly?
