A dominant figure, Kradyar, explores the depths of BDSM with a willing sub. The sub's cock is presented, throbbing and ready. Kradyar, with expert precision, inserts a cold, smooth metal rod into the sub's urethra, pushing deep until the head of the rod disappears. The sub's body tenses, but Kradyar's steady, confident touch keeps him grounded. The rod is twisted and turned, evoking groans of pleasure-pain as it rubs against the sensitive urethral walls. The sub's cock remains hard, a testament to the intense sensations coursing through him.
