Kynodesme2 presents an intense urethral exploration as a dominant partner teases and torments a willing submissive. With a powerful pump, the thick cock swells, veins throbbing. A metal sound is slowly inserted, stretching the urethra, as the submissive moans in equal parts pleasure and pain. The pump resumes, the cock pulsing, as the sound is twisted and slid in and out, milking every drop of pre-cum.
