Ryousuke321, bound and at the mercy of his own desires, introduces a daunting, unyielding steel pipe into his BDSM ritual. With a grunt, he pushes it against his throbbing cock, the cold metal sending shivers down his spine. He strokes it, the pipe's girth stretching his foreskin taut, before slapping it against his stomach, leaving a red mark. His body tenses as he imagines the pipe's relentless, unforgiving thrusts, his solo BDSM session intensifying with each steel-on-flesh impact.
