In the dimly lit party room, Margo Sullivan, the hot step-mom, spots her chance to turn the innocent teen daughter into a monster of jizz. She guides the girl's hand to Daddy's monster cock, hidden beneath his costume. The young girl, intrigued and horny, begins to stroke the massive shaft, feeling it pulse and grow in her hand. Margo, her voice laced with lust, encourages her daughter to explore further, to give Daddy a proper Halloween handjob. Daddy, unable to resist the dual attention, joins in, jerking off furiously, his cock leaking cum, ready to unleash his monster load all over the naughty step-daughter.
