Michelle and her brother, bound by blood and boredom, find themselves alone in the house. Their eyes meet, a silent understanding passing between them. They've fought their attraction for too long. Michelle stands, her body aching for his touch. She straddles him, her skirt riding up to reveal her lack of panties. He groans, his hands gripping her ass as she grinds against him. Their lips meet in a fierce, passionate kiss. She can feel his cock hardening beneath her. Suddenly, the front door opens, and they spring apart, guilty expressions on their faces. Their mother enters, oblivious to the sexual tension hanging heavy in the air.
