Cory feels a spike of jealousy when her stepson brings his girlfriend home.. the girls look at each other and seem to make a truce. There's enough dick here for them both. Ricks girlfriend licks his stepmoms asshole while he rams her hungry hole from behind. His stepmom eagerly eats his girlfriends pussy while she takes the shaft of his cock deep down her throat. Rick still can't tell a trapezoid from a parallelogram, but at least he won't have any problems with biology next semester.
