In a cramped, public bus, a straight guy's world is about to be rocked by a dominant, muscular hunk. The hunk, a regular on the bus, spots the straight guy and decides to make his move. He waits for the bus to empty, then pounces, pushing the straight guy face down onto the seat, his massive cock already hard and ready. He pulls out a tube of lube from his bag, lubes up the straight guy's ass, and his own throbbing cock. With a grunt, he slams his cock into the straight guy's virgin ass, fucking him raw and hard, the straight guy moaning and squirming, his own cock leaking pre-cum onto the seat. The hunk fucks him relentlessly, his balls slapping against the straight guy's ass, until he finally pulls out, cumming all over the straight guy's back, marking him as his own.
