This is an idea I've had, not sure how I want it to turn out but always wanted to play it.
I would be the nice/shy boy in high school. Good grades, well mannered, and a virgin. As luck would have it in my senior year science class I was partnered with the hottest girl in school, and also the biggest slut. I thought that if I helped you with your homework or cheated on a few tests I could finally loose my virginity. You however had other ideas. For while you WERE the biggest slut, you are trying to change your image before college. So your slutty outfits and detailed knowledge of how to get a guy off turned you into one of the biggest cock teases in school.
I'm looking for a role play partner that may institute a no cumming policy for me with the promise of sex, all the while making it EXTREMELY difficult for me not to want to.
