"Oh my word!" was the thought to say but words could not come from what was Kevin's mouth. There standing in true stallion glory was Kevin. His dark and almost black skin showing puffed veins running from head to feet. Long feeler hairs stuck out here and there. He blinked his wide separated eyes and as he took a breath his soft lips opened atop his flattened head to allow the air in.
His arms were gone, and legs merged into one flexible stalk. As he peered into the mirror a wild sexual passion was building. The feeling of an aching almost pain in his feet began to strain upward into his body.
Kevin tried to hold back the horrible pressure building but as his body grew very rigid the battle was lost. Suddenly with great force the surge of pressure roared up the length of his frame and with chug after jolting chug a stallion size load of yellowish and white cum shot out his mouth atop his very flat dic head.
As semen and gallons of cum splashed the bathroom ceiling Kevin stood in horror to see he had become a large stallion's balls and cock. Standing a good eight foot tall his dic body was a good three feet around. Kevin's feet were now huge testicles of a stallion LARGE!
His entire body was one large long round flat headed pony cock. He'd shed a tear if possible but even as he felt the terror of the reflection from the cum covered mirror he had another building surge.
Again like the first his cock body jerked from pleasure as load after load of thick globby yellowed semen roared up and out of his dichead's mouth. The ceiling, mirror and walls were becoming coated in congealing semen.
Standing still erect and with masturbation after sexual thrill Kevin's dic balls kept making gallons of cum and semen. Hour after hour we by as afternoon moved on to evening of the first day as a stallion's cock.
The pressure and surge was at first a real thrilling feeling but as hours passed the feeling waned. As morning sun light gleamed in the bathroom window Kevin looked about the stenched bathroom.
Strings of congealed cum hung from ceiling to floor. Globs of dried semen were stuck to the walls in all directions. The reflection of the floor saw congealed stuff a foot deep over the bathroom floor, "YUCK!"
The Summer's sun warmed the bathroom and with it gave an easy feeling to Kevin's cock body. Slowly at first his midsection softened and his cock head fell to bounce off the bathroom counter.
Kevin just was so tired he didn't care. Slowly his cock body was being drawn down into a sheath. It wasn't until his cock head felt the slime of horse cum washing over the face end of the cock head that he realized the depth of his flood of semen.
Suddenly Kevin knew if he relaxed into the sheath as a soft cock would he's drown in his own flood of horse come covering the bathroom floor. Who can say how his cock body would react but the fear brought renewed stiffness and quickly he stood up straight and hard again.
