In the throes of self-discovery, this curious gay man delves into the kinky world of urethral sounding. He's alone, but his mind is filled with taboo thoughts as he lubes up a metal sound. He pushes it into his urethra, wincing at the initial discomfort, but soon, the pleasure takes over. He fucks himself with the sound, his moans echoing in the empty room. He adds another, stretching his urethra wider, the intense stimulation bordering on pain. He's lost in the moment, his cock rock hard, pre-cum dripping. He can't hold back any longer. He pulls out the sounds, his cock pulsing as he cums hard, his abs glistening with his hot, sticky load.
