Jason´s bull balls in white cycling shorts...

It was a hot and sunny afternoon in summer when I went cycling with a friend. I was waiting for him and when he arrived I recognized his extremely tight and shiny white cycling singlet and the things in between his legs. I couldn´t believe my eyes: what kind of size was that bulge he had in this hot singlet? I couldn´t get my eyes off it and felt my dick growing and I said: "Hi Jason, how are you? Ready for our workout?" - "Yeah mate!" he answered. So we started to ride and talked about our exams in university. During our ride I couldn´t stop staring on this damn big bulge between his legs from time to time. I realized that it was not his cock that formed this bulge, cause he wasn´t horny at that time. I stared again - and what the hell - it was his balls!!! While pedaling his monster balls turned from one side of his riding stick to the other and once again back and back and so on...I still couldn´t believe it! Intense ball movement in a shiny white supertight short! I got so horny and my 8 inch dick was growing bigger and bigger. "You like it, Alex?" Jason asked and grinned. But before I could answer his question my cock exploded! I shot seven or eight massive cumloads in my wetlooking lightblue cycling shorts while riding...now the shorts was really wet!!! Some cum was shot thru the lycra and dripped down my left leg. Jason moaned: "damn, Alex! what a shot!!" We stopped at a bank next to a little forest and Jason looked at me and my cumfloated blue bulge. I sat down and so I had Jason´s bull balls directly in front of my eyes! It was amazing...each had almost the size of a billard bowl! He laughed and said: "You´re cool, bro. Never saw a guy cumming while cycling! You know that I love cum?" He grabbed his bulge and I saw his dick and a wet spot growing bigger and bigger in his white tights. Then he pulled them down. First he grabbed his hard 5" cock with the big head, then he grabbed his balls out of his tights. Monsterballs I had never seen before!!! Jason was so horny that his precum already dripped on the ground. He slowly pulled his foreskin back and his precum began to flow more and more...He repeated that and started to moan. His dick with the big head exploded!! His first squirt hit the tree behind me, the second squirt was a facial! Wow! Jason couldn´t stop cumming! He squirted 13 times and my blue singlet was covered with his creamy white cum! "What a huge load, Jason!" I said. "I got lots of that in stock in here..." he laughed and grabbed his plump hanging balls "Don´t worry! There´s enough for another load, hehe!" "You look like a...let´s go back to my home and change our gear, Alex!" Jason replied and grinned. So we ride back to Jason´s home. My whole blue gear was covered with wet spots of Jason´s and my cum. This is not the end of this amazing afternoon of boyfun and boycum... to be continued!
