In the dimly lit room, he starts his verification. He's solo, but his task is far from enjoyable. He takes his cock out, already semi-hard, and begins to stroke. But this isn't for pleasure. He's here to prove his endurance. He wraps a thin, harsh rope around his shaft and balls, pulling it tight. He gasps, his body tensing as the rope digs into his sensitive flesh. He adds another, and another, each one sending jolts of pain through him. His cock throbs, engorged and aching, as he fights to keep going, his body covered in a sheen of sweat.
