Vacation brings out the kink in this married family. Boy Austin, a slender twink, can't keep his eyes off his step-dad's massive cock. One sultry afternoon, they find themselves alone by the pool, and Austin can't resist. He straddles his step-dad, his tiny body barely containing the enormous cock that's about to invade him. Robbie110 holds his step-son's hips as Austin slowly sinks down, his tight hole stretching to accommodate the thick girth. Austin's face contorts in pleasure and pain as he begins to ride, his smooth, hairless body glistening with sweat and pre-cum. The family vacation just got a whole lot more interesting.
