In a dimly lit room, a young man, anonymous yet confident, takes center stage. His eyes locked on the camera, he slowly unzips his jeans, revealing his hardening cock. He's here for one purpose, and that's to explore the depths of his urethra. With a gloved hand, he lubes up a thin metal sound, the cool metal a stark contrast to the heat of his body. He teases his slit, applying gentle pressure, before slowly inserting the sound. His breath hitches as it slides in, his cock throbbing with a mix of pleasure and discomfort. He pushes it further, inch by inch, until it's fully inserted. He moans, his eyes rolling back, as he begins to thrust his hips, fucking himself on the sound.
