Mistress Nikki – Stretched Dick Hole, Urethral Stretch and Depth Training

Mistress Nikki delivers intense urethral play in this dungeon scene. With her slave’s passage already widened, she pushes the limits further by testing both girth and depth. A size 11 steel sound ensures his urethra is fully open before she introduces a 40cm silicone sound, 11mm thick, to challenge his endurance. Every centimetre disappears inside, leaving him at her mercy as she slides it in and out with sadistic delight.
