Backdoor Lust

High school senior Robert finally secures a date with the most sought after senior virgin on campus. He arrives at her door confident that he'll be able to brag that he was the first to deflower the chaste beauty, but when he's greeted at the door by the girl's stepmom, he's smitten by her healthy rear-end, and though he never lusted for backdoor sex, he simply can't resist the available woman. However, what happens when the sweet virgin girl catches him defiling her step mom? He demands that she join them, of course.
