Johnny's luck takes a tantalizing turn when Sofia Su, the family's naughty little secret, propositions him with a wicked wager. If she can make him cum with nothing but her mouth and pussy, she keeps his money, but if he holds out, she forfeits her sweet, tight cunt to him. Johnny agrees, and Sofia, hungry for victory, climbs onto him in reverse cowgirl, her wet pussy enveloping his throbbing cock. She bobs up and down, her blonde hair swaying, as she takes his shaft deep into her throat, her tongue swirling around his tip. Johnny's hands roam her body, pinching her nipples and spanking her ass, leaving red handprints as Sofia's pussy clenches around him, determined to win the bet and keep her prize.
