A stepfather, who is a member of the track and field club, can't help but lust after his cute stepdaughter's big, plump ass in her racing bloomers, so he secretly mixes an aphrodisiac into her drink... The aphrodisiac's effect causes her stepdaughter to lose all sense of reason, and she loses control, masturbating on the corner of the table and climaxing herself... Her stepfather, who can't suppress his erection due to his lust, straddles her face and rubs his crotch against it, climaxing even more! She mounts him and wriggles her hips in a lewd manner, begging for continuous creampies!
