Last time when Sebastian came to visit the clinic I noticed a slightly enlarged prostate so I asked him to set up an appointment with Nurse Cindy to check up on it. When he came in he was a bit nervous but I assured him that it would be a simple procedure. After checking his vitals I asked him to undress and hop back up on the exam table. I did a quick digital examination and concluded that a mild electrostimualtion session would help ease any inflammation of the prostate. Immediately I prepared Sebastian for the insertion of the electro-butt plug with some simple anal relaxation that I learned from Dr. Phingerphuk techniques. After preparing his hot tight hole, I pulled out the stir-ups and inserted the plug ever so gently until it popped into place. The boy's reaction was that of slight discomfort but, I assured him that the rest would be easy. As I turned on the device, he moaned from the sheer pleasure of it. His rectum pulsated to the rhythm of the electro-settings. It was no surprise that after massaging his penis for a bit, it exploded with huge amounts of semen! I think he's gonna wanna come back for more.
