"What are you doing Mark?!" Sei screamed. Sei could do nothing but watch as Mark transformed into....this thing! He was afraid to help him because he feared he would go through the same change.
Mark\'s changes continued and caused his shirt to rip in half, exposing his newly formed muscles and body hair. "Seriously, STOP it Mark! You\'re scaring me!" Sei looked to see again that Mark\'s face had elongated and formed a muzzle.
Sei ran out of the room to look for help while Mark was stuck, all alone in the room. Mark\'s clothing continued to rip even more. RIIIIIIIIP went his pants as they split from the seams. His underwear was now showing, along with a big bulge that didn\'t stop growing. Mark tried to scream, but all he could do was watch the changes that took place. He felt tremendous pressure coming from his crotch. Finally, it split wide open, revealing his hardened cock pointing out of its sheath. Mark looked around and couldn\'t see a trace of his old self. All he could do is wonder what would happen to him, and what happened to Sei.
A few minutes later with no help, Sei returned to the room to find a horse running around the room. It neighed to Sei. Sei felt as if Mark was asking for help. "Don\'t worry Mark, I\'ll find someway to change you back" said Sei as he started to pet Mark. Mark winnyed with pleasure as he started to lick Sei. "EUGH! Gross Mark!" Sei started to back up, wiping drool off of his face as he tripped on something and lost his balance. He fell to the ground and couldn\'t see anything and accidentally grabbed something off of the floor. What was it?
