In the dimly lit room, a lone figure, Blackteufel's soloboy, begins his intimate ritual. He fearlessly spreads his legs, revealing his tender flesh, as his eager hands navigate his sensitive anatomy. A glistening metal rod, a tool of both pleasure and pain, is meticulously lubed before being gently inserted into his urethra, a slow descent into the depths of his being. His moans fill the room as the rod massages his prostate, but he's not done yet. He switches to a chastity device, his cock struggling against the confines, a cruel yet arousing form of CBT.
