In this extreme gay BDSM scene, a skilled top explores his bottom's limits with urethral play. Starting with a gentle fingering of the peehole, he gradually introduces larger objects, from dedos to a catheter, dilating the urethra and drawing out moans of pleasure and pain. The bottom's penis is stretched and filled, his prostate stimulated, as the top expertly manipulates the catheter, pushing him to the edge of his endurance.
