Naked and vulnerable, the sister's fingers dance over her wet, throbbing pussy. She's consumed by the thought of her brother's massive cock, imagining it stretching her tight hole. Her heart pounds as he enters, her body aching for his touch. But he's oblivious to her desire, his mind elsewhere. Frustrated, she continues her self-indulgence, her fingers picking up the pace, her breath hitching as she nears climax, her body yearning for more than just her touch.
