As his friends recover from the shock of being covered in horse cum, Kyle quickly pulls up his pants as best he can, trying to stuff his deflating stallionhood down a pant leg. As he finishes pulling his pants up, he bolts out of the house and down the street to his home, which luckily was only two blocks away. "I can't believe I just did that!" He thinks to himself. Even then, he could feel pressure building up in his balls; like he hadn't cum in days, even though he just had a few minutes ago!
As he runs, he can feel his gigantic equine member jostling in his pants. It was a good idea to wear sweats today, Kyle reminisces. All that running and friction though was having a pleasant, if unwelcome affect on his new addition. As he slowed down, turning into his driveway, his hand absentmindedly strokes along the front of his leg, coaxing more and more length and girth out of his monstrosity. Reaching his front door, he stops in place, completely overwhelmed by the feelings and pleasure of rubbing his now-erect cock, pointed straight down his pant leg.
His breathing sharpens as he realizes what he's doing and as he approaches another monumental climax. He instantly withdraws his hand and slides through the door, but it was too late. Without any hand stimulation, he feels the pleasure cresting in his dick, the cum pumping up from his orange-sized balls into his man-tube, as the head of his cock begins to swell and grow out into a trumpet shaped flare. Closing the door, he stands still, his muscles locking up as another gigantic orgasm washes over him, his cock firing for a solid two seconds as cum blasts down his pants and soaks into the material, then down his leg and onto the floor. Before he can even take another breath, it fires again, and again, what felt like gallons but must have been pints of his cum. After what felt like a minute of orgasm, it dies down, and Kyle slumps down to the floor, sitting in a puddle of his own sperm. He notices it has a much thicker, chunkier texture to it than his old, he shudders, Human cum. Once again though, he feels his balls swelling up with another load of cum.
As he catches his breath, he decides what to do next.
