In the heart of a cold, sterile dungeon, a slave stands, his body bare and vulnerable, his mind a whirlwind of anticipation and dread. Before him, a simple mousetrap, its steel jaws glinting menacingly under the harsh lights. His task? To place his most precious, delicate cargo - his heavy, ripe balls - onto the trap's plate. With a deep, shuddering breath, he inches forward, his cock already hard, his balls already straining. The trap snaps, capturing his orbs in a brutal, unforgiving grip, his cries of pain and pleasure echoing through the empty chamber.
