When Marco's mom sends him to his room, he finds Mia hiding in the closet, trying to escape their stepfather's wandering hands. Their mother's absence has left the house a powder keg of sexual tension. Mia, her round ass pressed against Marco's crotch, feels his growing hardness. As they struggle to maintain control, their stepfather walks in, commanding them to fuck. With a mix of fear and desire, Mia guides Marco's thick cock into her tight, untouched ass, riding him slowly as their stepfather watches, his own cock hard in his pants.
