In a hidden closet, a curious sister stumbles upon her brother's massive erection, tenting his pajama pants. Unseen by him, she watches, entranced, as he strokes himself, lost in his own world. Her heart races, her breath hitches, and she feels a warmth between her legs. She knows she should leave, but she can't tear her eyes away from his thick, veiny cock. As he picks up the pace, she finds her hand slipping beneath her nightgown, mirroring his actions, her fingers brushing against her wet, aching clit.
