A curious and adventurous twink explores the intense world of CBT, focusing on scrotal stretching. In the dimly lit room, he starts by gently tugging at his sensitive sac, his soft moans filling the air. He slips on a cock and ball device, feeling the pressure build as his scrotum stretches and his balls ache. He gradually increases the intensity, using weights and clamps, his body writhing with a mix of pain and pleasure.
