I work hard at getting a straight man to let me fuck him. I lead him into thinking that he's gay curious. Once there, he's going to have his first gay encounter.
I ask him first, is he gay, if he denies I ask if he's sure, eventually getting him confused and lead him to think he really might be gay. Then getting him to receive anal, and now he's mine, but our secret.
Once I've done anal a few times, I manipulate him into believing that he has to do oral with other guys and that he has to swallow. In five years I've had sex with at least ten guys a year, all of them bottoms or they go both ways, but they all take it up the ass.
