As soon as he was around the corner of the barn door, Kyle began moving as fast as he could, what with that monster horse tool of his jostling in his pants. His mind was swimming with images of that stallion's mottled cock ramming into the beautiful mare. His cock was almost to it's full length as he reached the outhouse. As he hurriedly squeezed into the little shed, he slammed the door and bolted it shut before ripping his pants off. Well, he tried to anyways.
As he pushed the pants down, he realized he couldn't push far enough to clear his flared penis. Awkwardly, he bent on one leg, as his other leg was held straight by his now full-length erection, and was able to release the beast. As soon as the denim was past the tip, it sprung up and smacked against his chest wetly, the precum already flowing. Kyle sat down and got to work.
His hands ran up and down his sensitive length, lubricated by his copious precum. Kyle was really getting a feel for how to make this horse cock feel good. In his lust-addled mind, he tried to think of what a horse would feel while rutting. The medial ring would be sliding in and out, so he positioned his left hand over the ring. The head would always be inside the mare, so his right hand reached up to the blunt, flared tip.
Kyle bit his lip as orgasmic pleasure flowed through his member, like hot electricity buzzing on his skin. In a moment of clarity, he realized he would have to clean up all the cum so he didn't infect anyone, but he couldn't bring himself to stop, even for a second. He tightened his right hand over his flare as it began to swell, almost doubling in width. His hand putting pressure against it felt absolutely heavenly. Once more, he felt the build up to another monumental equine climax. A spark of heat built deep inside his hips, his huge balls churning and tightening up against his sack.
Kyle could only watch as his penis began convulsing and spasming, the fire flowing up his dick. When it reached the tip, a deluge of chunky equine cum shot out of him, and did it ever shoot! Up to the roof it went, splashed off, and landed on and around him. Using his right hand to aim, he stood up, turned around, and pointed his dick at the toilet just in time for the next shot. His knees almost gave out from the overwhelming sensation of cumming so much. One more explosive shot of cum arched out of him, before his dick started drooling a river of cum, his orgasm winding down. He turned around once more and sat down as he recovered.
