Leo stopped by again to see if I could help him again with his final exam. I asked him why he left the last time he was in and he explained he had class and couldn't wait any longer. So as I'm explaining the prostate and it's function Nurse Cindy calls and says that Angel is wanting to see me again about his preseminal fluid issue. I figured I'd kill two birds with one stone and asked if it would be alright if Leo stayed and watched the prostate massage procedure. After Angel undressed I prepped him for the digital exam..he instantly became aroused..nothing surprising because that's what happens when your prostate is stimulated. I noticed Leo was focused on Angel's thick piece of meat so I instructed him to suck it a little in order to get the juices flowing. Leo sucked Angel's throbbing dick as if it were a delicious ice cream cone. At this point Angel's cock was leaking but I wanted to make it leak even more so I inserted a prostate stimulator and made Leo suck Angel's dick even more. I guess the combination of the prostate stimulator and Leo's sucking action made Angel's dick explode like never before! I watched as the prostate stimulator pulsed with Angel's ejaculation. Very interesting indeed!
