Kyle did his best to keep up the fight until he knew that Cory would get both.
"For your transformation, you will become part John mule." Kyle said with a grin of triumph. " For your dare, you will become completely submissive to me and will follow every command I give you exactly as I give it to you."
"You can't do tha..." Cory's objection trailed off as his changes began to take place. His muscled figure became completely covered in brownish gray fuzz. Cock lenghthened from its impressive (by human standards) eight inches to about a 16 inches with a hairy foreskin covering his mottled dick. His balls dropped a little lower and his nipples darkened to a deep gray. His face stayed pretty much the same except for a bit larger teeth, more facial hair and ears with an obvious point. The most remarkable change was the look in his eyes. Gone was the brash confidence that led him to force himself upon Kyle in the first place. Instead, his eyes were empty and listless like the windows of an empty shop.
Kyle motioned to one of the benches in the locker room and said, "Lay across that bench with your ass facing me." Cory turned and laid on the bench displaying his ass and the short rail that he had assumed as part of his transformation. Kyle went to the equipment locker at the end of the room and began to think of a plan.
Jennifer watched as each of the Gros stripped to reveal the gray and pink horse pussies that they had now been afflicted with.
Two if the girls were crying but most were silent and shocked. Jennifer went over to Pam, the one who had convinced the others that her slutty night with the basketball team had been a wild fantasy, and began to touch the swollen horse cunt that had appeared between the girl's legs.
"Does it hurt when I do this?" Jennifer said while playing with the girl's massive clitoris. "NooOahoo!!" Pam moaned as she reacted to the stimulus.
The other girls watched and began to tentatively explore their modified organs. With every touch, brush and fingering, their arousal was heightened. Jennifer watched in awe as the more aroused the girls got, the faster their changes progressed.
