In the dimly lit room, Michelle's breath quickens as she strokes her throbbing clit, her eyes locked on her stepbrother's massive cock, mere inches away. She'd caught him jerking off earlier, and the sight of his thick, veined shaft had been seared into her mind. Now, she can't resist the urge to satisfy her own needs, her fingers plunging deep into her wet, aching pussy. Her moans fill the room, echoing the silent cries of her brother, who's struggling to maintain his composure, his cock twitching with unspent desire.
