Mark's dorm room is his personal sanctuary, a place where he can indulge his fantasies without judgment. Today, he's lost in a vivid daydream about his stepmother, his hand moving rhythmically over his stiffening cock. Suddenly, the door creaks open, revealing his stepmother standing in the doorway, her eyes wide with shock. Mark freezes, his dick still in his hand, as his stepmother's gaze flicks from his face to his crotch and back again, her own body reacting to the unexpected sight before her.
