In this intense BDSM session, Soundingbear takes on the role of the eager sub, allowing his friend to explore the limits of his urethral endurance. The Brazilian stud's thick cock first gets a thorough cleaning before the real fun begins. A series of urethral sounds, from small to increasingly larger, are gently inserted into the bear's piss hole, stretching it to its limits. The intense sensations of CBT make the bear's cock rock-hard, as his friend expertly stretches and teases his urethra.
