This was actually the very first time I got to use the Anal Intruder Cockring on a patient. I try to select very open-minded patients when I'm experimenting with new toys or techniques and this guy is open to just about anything. My favorite kind of patient! Once I got all his good parts inside the cockring and locked into his ass, I tried various sizes of rubber cockrings around his balls.
He was very excited about this and was already dripping pre-cum with anticipation. After getting him prepped, I put his swollen cock into the Venus 2000 milking machine. This was doing a nice job of stroking his cock but as added stimulation I held a small but powerful vibrator against the metal bar of the Anal Intruder Cockring. This transferred the energy to his prostate and got him off with a very intense orgasm.
