Bound tightly, a man's cock stands rigid, aching for release. He watches as a glistening urethral sound, thick and menacing, approaches. With a deep breath, he relaxes his body as it's gently inserted, stretching his piss hole wide. He moans, sensation overwhelming, as the sound is slowly worked in and out. Cum leaks from his cock, dripping onto the floor. He begs for more, his body tensing as a second orgasm rips through him, his urethra filled with hot, sticky cum.
