In the intimate, dimly lit space, a curious soul dares to venture where few have gone before. Armed with a sleek, 6mm flexible toy, he begins his urethral odyssey. The toy's tip breaches the opening, and he gasps at the unfamiliar sensation. Slowly, he pushes it deeper, feeling every millimeter of his body's uncharted terrain. His cock throbs in sync, craving attention. He obliges, stroking himself as he fucks his urethra, the dual stimulation sending waves of pleasure coursing through him. His body responds eagerly, lubricating the toy's path as he picks up the pace, racing towards an explosive, urethral-induced climax.
