In a dimly lit lab, Payton Preslee and Bunny Madison, two curvaceous scientists, are interrupted by their eager colleague, Rion King. He's hungry for an experiment of his own - one that involves their luscious bodies and his throbbing cock. In lingerie and lab coats, they resist initially, but the taboo allure of their situation proves too tempting. Preslee's big tits heave as she sucks King's dick, while Madison's thick ass grinds against his face. They take turns riding him, moaning as his length fills their wet pussies. The free-use fuckfest ends with King's cum painting their faces and Preslee eagerly swallowing his load.
