Kynodesme2 captures a solo male's intense exploration of extreme cock and ball torture. Clad in a black leather harness and chained cock cage, he inserts a 10mm sound into his urethra, wincing at the initial penetration. His ball sack, filled with steel balls, stretches taut as he adjusts to the intense sensation. He moans, pleasure and pain mingling, as he slowly works the sound in and out, his caged cock throbbing with each movement.
