Slavery: A series of erotic games (book 01)
"Because I'm not and never have been attracted to men. I mean, I know your Master is handsome, but I'd never want him to fuck me. I'd much prefer to fuck you. Sexuality isn't really determined by who you have sex with, but by who you want to have sex with. Take people in prison for instance. I'm sure men have sex with other men in prison, only because there aren't women there to have sex with. They still have sexual needs and so they use other men to satisfy them. Once they leave prison, they won't have sex with men again. They have no desire to. You've licked cunt now. Are you a lesbian because you've licked cunt?"
"I guess not."
"Are you bisexual?"
"I thought I must be, as I'm doing both."
