The bi-curious professor in the sauna Part 3 SeXStoRY

Over time the professor admits that he likes it when I play with my balls and pre-cum. He really likes it when he can see my balls flop about when I masturbate. One Friday he asks if he could fondle my balls. This would be the first time that either of us has touched each other’s junk. He takes great interest in every detail of my ball sack and its contents. Not a testicle or tube was left untouched or not examined in great detail. The professor explains that is it a man’s balls that makes a man a man and not his penis. The balls produce the seed of man while the penis is the delivery mechanism of the seed. He tells me that he can tell from what he can feel in my balls that I am truly a man. After several minutes of what could be described as worshipping my balls he goes back to his corner of the sauna bench and masturbates. Fondling my balls must have been a major turn on for the professor because he quickly reached organism. I found it enjoyable as well and also came quickly. After one Friday encounter the professor asks me to not have sex or masturbate until we meet again. He wants to see how much I can cum if I am not sexually active. Thinking it would be interesting I agree. A week goes by and we meet again in the sauna. As usual the professor fondles my balls. He comments about how much sperm he can feel in the tubes. He asks me to masturbate while he plays with my balls. As I have not had sex in a week and the fondling was enjoyable I quickly reach orgasm. I shoot out a large load of cum onto my stomach. The professor smiles and suggests that I continue to masturbate since I still have a hard on and he can feel that there is still a large amount of sperm in my ball sack. The professor continues to play with my balls. After several minutes I shoot out another large load of cum onto my stomach. The professor is clearly pleased. Since I still have a hard on and the professor was still fondling my balls I continue to masturbate. It takes longer but I eventually shoot out another load of cum. The professor tells me that he is proud to see the amount of cum my balls produced. The professor starts to run his index finger through the cum on my stomach. He plays with the cum for several minutes while masturbating with his other hand. He wipes the cum from my stomach with his hand, stares at it, and then wipes most of my cum onto his throbbing cock. He licks the remaining cum off his hand and tells me this is the first time he has tasted another man’s cum and that it tastes great. He then reaches down and starts to masturbate using my cum as lube. He reclines back with one leg hanging over the edge of the bench. Using my cum as lube really excited the professor. His hips kept thrusting while he was masturbating. The professor started masturbating faster, arched his back, and let’s out a loud guttural groan of pleasure as he shoots out an impressive amount of cum as he climaxes. His hips continued to thrust during and after his climax. “Wow! That was intense!” the professor exclaims. The two of us recline on the bench, relax, and let our cocks go limp. The professor’s cock was still cum covered. We exit the sauna, shower, and go our separate ways as we usually do
