Urethral sounding and urethral play are also used to refer to this practice in a sexual context. Dominic Is fascinated with this beautiful cock play and has a collection of gold tip probes rods he likes to use on himself. Working his Urethral hole open and lubing it up good with a smaller rod, he then reaches for something thicker to really stretch his hole wide. Massaging his cock from the inside Dominic loves to shove the probes deeper and deeper down to the base of his cock until he has an explosive orgasam.
