I fixate my slave with his legs wide-spread onto the gyn chair and slowly push a thick dilator into his urethra. He moans loudly and his cock turns hard in an instant, as I push the sound even deeper into his dick... I tell him that he´s not allowed to cum, because I need his pure horniness. He needs to endure many more centimeter of intense urethral penetration! Next, I lube up a much longer beaded dilator with Instilla gel. I show it to him, before I insert it into his dick bead after bead. The long dilator disappears completely, until it sits deep in his bladder. I pull it out a tiny bit again and fuck him with it: Merciless & Deep. He gasps and thanks me for giving him this kind of perverted attention. His cock throbs around the dilator, as he desperately fights his climax. I keep him right on the edge and make it clear, that I am the one in charge...
