Mikey's daily life takes a steamy turn when his sister Mel catches him masturbating with his enormous cock in hand. Instead of shaming him, Mel's breath hitches with lust, her pussy dripping at the sight of her brother's massive member. Mikey, emboldened by her reaction, guides Mel's hand to his shaft, teaching her how to stroke him. Mel's inexperience fuels her eagerness, her small hand struggling to encompass Mikey's girth. Mikey, unable to resist any longer, lifts Mel's skirt and plunges into her wet, waiting cunt, filling her completely.
