In the dimly lit bedroom, Michelle's eyes widen as she spots her brother's tented pants. He's been stroking his hard cock, unaware of her presence. She watches, her heart pounding, as he jerks off, his thick shaft disappearing into his fist. Michelle's pussy pulses with desire, her breath hitching as she imagines her brother's cock inside her. She can't resist the urge to touch herself, her fingers slipping beneath her panties, rubbing her clit in time with her brother's strokes.
