Ryan was stark naked, his cargo shorts, jockeys, t-shirt and flipflops in a pile next to him. His cock was rigidly erect, I'm guessing, would have been about 7-1/2 inches or so - quite a bit bigger than mine - but nowhere near the lodge pole in between Dexter's legs. But his nuts were absolutely huge, swaying back and forth in a big, dangling loose scrotum between his legs. He'd obviously been standing there jacking himself off listening to us.
You could have heard a pin drop in the room, as he swayed his hips and his genitals swayed back and forth. Suddenly, his face grew red and he put his hands on his hips as he kept swaying back and forth.
Ryan let out a low 'U-u-u-n-n-n-h" and a large rope of precum squirted out of his cock. He panted briefly several times and then another deep groan and another long strand of precum fell out of him onto the floor. And then he shuddered and let out an almost animal cry and one enormous long continuous jet of sperm burst out of him and shot up into the air above his head. Amazing - without even touching himself he'd gotten off in a way that would make a pornstar proud. He stood there flushed, and gasping, more sperm dripping out of his cock onto the floor. I glanced over and saw most of his volley had hit the wall of Dexter's bedroom, nearly six feet away, and was rolling down towards the floor.
"'tha FUCK!" Dexter exploded. "What are you doing to my goddam bedroom you little moron? And what the hell do you think you're doing here spying on us?" Rounding on me he yelled, "What is it with you two?"
I'll give Ryan credit, as much abuse as he took for his compulsive masturbation he was awfully good natured. He took this tirade in stride just like all the others he endured. "Hey," he said mildly. "After I left here I went over to Rithy's and we played around awhile."
This sent Dexter over the edge. "Rithy? RITHY? The exchange student? Jesus, he barely even speaks English!" This caught my attention for two reasons. One, for Ryan to get off like that right after horsing around with some other guy, everything he said about his prodigious sex drive must be true. Second, Rithy's monobrow and incredibly hairy forearms had been on my mind ever since he showed up in school mid-year. All of a sudden my mind was alive with possibilities.
"Well," Ryan said with a faint smirk, "his English doesn't have to be all that good for what I wanna do with him. But, we got done and I figured I'd come back and see if what you guys were up to. And, I guess, up is the operative word, isn't it?"
Fuming, Dexter stomped over to his nightstand and grabbed some cumrags and hurled them at Ryan. "Here, clean up your mess you little jerkoff artist. I'm going to get a beer." He tugged on his swimsuit and stormed out of the room leaving Ryan and me alone.
Ryan and I looked at each other and started grinning like fools. "God, he's such a dork but he's so fuckin' hot. How did you ever manage to organize that?" asked Ryan. "I'm still not quite sure," I replied, "but it sure was fun. Rithy, you say?" Ryan's lazy smile spoke volumes. "Yeah, Rithy," he said. "You wanna come over sometime? His sponsors are never home."
He set about cleaning up the mess he'd made on Dexter's wall, and I set about cleaning up the mess Dexter and I'd made in the closet and after about 10 minutes the room had stopped reeking of cum and looked good as new. We got dressed, took the small pile of sopping cumrags downstairs and threw them in the washing machine downstairs. |
