Alone in his room, Estim, a young man with a penchant for extreme self-pleasure, begins his daily ritual of CBT. He expertly applies clamps and weights to his throbbing cock, his moans muffled by the tight gag in his mouth. As he edges himself, he uses his trusted HFO machine, pushing his limits with each intense pulse. Sweat drips from his body as he struggles to hold back, his eyes rolling back in ecstasy.
