In 'Mastering Pain,' Noriktoxic delves into the raw, unapologetic world of gay CBT. A dominant, tattooed hunk trains his submissive to take immense, ball-aching pain. With expert precision, he stretches, squeezes, and torments the bound, vulnerable balls. The sub's moans of agony fill the air, but his cock remains rock-hard, betraying his body's complex response to the intense, prolonged stimulation.
