In a cramped, dimly lit room, Mailuumex and Mexi, barely legal and barely clothed, submit to the will of Mailuumex's friend. He, a towering figure with a massive cock, commands them to touch each other, to kiss, as he watches, stroking his hardness. He slips into Mexi first, her tiny body trembling as he stretches her tight hole. Mailuumex, jealous and aroused, begs for her turn, and he obliges, filling her with his thickness, their cries of pleasure echoing. He cums inside Mexi, then Mailuumex, leaving them spent and marked, their bond forever changed by their taboo debt payment.
