Besides having a 12+ inch, thick cock I also have proportionally large testicles and more than a few people have enjoyed holding them in their hands. My testicles are about the size of lemons and hang somewhat low, probably due to their weight. Now, I'm not sure if there is correlation between my testicle size and my volume of semen but I will say that I produce a LOT of cum. The problem is that I often feel like I'm a human geyser that needs occasional release or the pressure will build up to an explosive level. If I do not have release multiple times a day my testicles will ache and I'll get a constant uncontrollable erection.
I have become an expert on surreptitiously masturbating in public. I have masturbated at my desk at work, on a bus, and even on a plane. My trick is to put a condom on my dick (largest brand you can buy) and rub my cock under my pants. Once I'm done I can visit the bathroom and drop off my deposit. In one instance, I was on a long plane ride and I did not have a condom. I was sitting next to a woman and I could feel the pressure building. What I did was try and give the impression that I was feeling sick. I put a blanket over myself, pulled out my dick and put it in my mouth. The woman would never assume I was sucking my own cock because my dick is long enough that I didn't have to bend over that far. Then I just squeezed my dick repeatedly rather than stroke it which would have attracted attention. I could see through the blanket and watched the woman next to me as well as stewardesses walking down the aisle even as I worked my massive dick. This extraordinary pubic masturbation caused me to absolutely unload into my mouth and I worked hard to suck up all the cum and lick the tip of my cock clean before pushing it back down into my pants. It was clear that none were any the wiser as I removed the blanket and held my temples faking a headache. I smiled at the lady next to me but tried to keep some distance given that my breath probably reeked of sperm.
It occurred to me, one day, that if I was producing this much cum while ejaculating multiple times I day then if I waited a few days I would accumulate an even more significant volume. I simply could never bring myself to not ejaculate because of aching balls and quite frankly because I loved ejaculating. I decided I would avoid masturbation for several days and see what happens. However, I felt like an alcoholic in detox. I used some personal time off and just stayed in my apartment for a few days watching anime and playing video games. As the first day wore on my balls starting to ache and I found myself laying a pillow over my now erect cock and pushing down just to try get some feeling without actually cumming. It was an embarrassingly rough day and I even got a few calls from people asking if I were up for some 'fun' but I declined.
