While packing his things to leave for college, Jay notices a particularly heavy box. Inside of it was a giggling Madison, his stepsister, curled up inside. Laughing innocently, she reminds him of a half-forgotten promise - a playful vow to take her virginity before leaving for college. Caught off guard, Jay tries to get out of the situation. Madison, however, was not to be swayed, so she sucks his dick to show him how serious she is. The next day, Madison surprises her stepbrother once again with a kinky show involving a giant dildo. Jay, despite the impending college life and the absurdity of the situation, finds himself drawn into Madison's impromptu show. Finally, Jay’s last night at home arrives, and he is determined not to let Madison down. A man of his word, he takes his stepsister’s virginity and gives her a nice facial to remember him by.
