Cory feels a spike of jealousy when her son brings his gf home.. the chicks view at each other and seem to make a truce. There's enough wood here for them both. Ricks gf gobbles his stepmoms bung while he catapults her hungry fuckhole from behind. His stepmother anxiously licks his gfs pussy while she takes the weenie of his trunk 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.
