For me it's just about how much of a freak the bitch is that's a turn on. This young lady says "Do you want to jack off and cum in my face" (actually I think she said wank, she had a british accent). I'm like "Sure thing". Next thing you know, she's on her back and I'm straddling her face.
I was thinking to myself "Man, I thought that Russian domestic violence victim from the restaurant was a freak, and the girl from work with a rape fetish was disturbingly freaky, but this girl is really raising the bar."
Then she just lays in bed for a half hour with nut all in her face like "you don't want to cuddle?" LOL. "No indeed, that's what your boyfriend is for sweetie. Where the fuck are my pants?"
