When she hears noise coming from her stepsons bedroom, Cory Chase goes to see whats going on. She finds her stepson, literally his head against the wall in frustration. Hes studying for a geometry test and no matter how hard he tries, he just doesnt get it. His stepmom doesnt know shit about geometry but she does have an idea of how she might be able to help suck the frustration right out of his dick. The next day, Cory feels a spike of jealousy when her stepson brings his girlfriend home.. Cory can barely conceal her contempt as she looks at the simple expression on the girls face. What does his son see in this girl? Aside from the blonde hair and hot teen body, of course. He takes his girlfriend upstairs, leaving his stepmom to stir in the juices of her jealousy downstairs. When Cory hears the little slut choking on her sons cock she decides enough is enough. She hatches a plan and places a call before going upstairs to let the girlfriend know her car is being towed! Now that shes away, stepmom can play.When his girlfriend comes back, she walks in on the stepmom, kneeling in front of her boyfriend and sucking his cock like her life depends on it. Fuck that! She pushes his stepmom out of the way so she can get her mouth around that cock. In that moment, the girls look at each other and seem to make a truce. Theres 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 cant tell a trapezoid from a parallelogram, but at least he wont have any problems with biology next semester.
