I begged my little sister not to go on a date with my bully.. I told her that he wasn't looking for a girlfriend, just to use her for sex to humiliate me. She smiled and said "sounds fun".
As much as I love crazy sex, the sight/sound of another cute girl a few feet away getting the same treatment (or worse!) always makes it 100x hotter. This is why I like swingers clubs... (x-post /r/gangbang)
