Rapture leads her pet into the dungeon, where she effortlessly picks him up & does a few squats to show off her strength. Then, she lays him down & starts to stroke his cock & play with his balls. She gets him good & worked up, then she stops & does a few more lifts with him, flexing her huge biceps.
She continues, placing her pet down & stroking his cock some more. She wraps her huge bicep around his cock, stroking it fast & faster, until he finally cums. Rapture finishes the clip by flexing all of her muscles, and then masturbating.
