Pafatguy, a seasoned masochist, pushes his limits in this intense CBT session. He begins with a penis pump, the vacuum creating a throbbing sensation as his cock swells. Next, he inserts a sound, the metal rod stretching his urethra, evoking groans of pain and pleasure. The uploader, Pafatguy himself, captures every wince and gasp, as he explores the depths of his endurance.
