Amateur stepsister's flirtation leads to gay encounter and denial

After a steamy encounter with his step-sister, our young protagonist is left with an intense craving for some guy-on-guy action. He's got a thing for big asses and big tits, and his step-sister certainly doesn't disappoint in that department. But the taboo of sleeping with his step-sister leaves him yearning for something more. He's got a thing for college boys and amateur studs, and he's not shy about seeking them out. So, when he stumbles upon a hot video of a guy fucking a girl, he's quick to jump on it. The sight of the girl squirming and squirting as she's taken hard and deep is enough to get him rock hard. But when he sees the guy's tight hole being stretched wide open, he can't resist the urge to join in. He's not your typical straight guy, but he's got a thing for gay sex. And when he finally lets go, he's left with a hot load of cum to prove it.
