"Amber we have to stop! I'll keep changing if we can't find a way to stop it and all your doing is speeding it up! And... And.. Amber! Look at yourself! Your changing too!"
Amber snapped out of her delusional lust driven state and stood up. "Oh god Jen, I'm so sorry, what have I done!" Amber walked over to a nearby mirror to examine her body. Her ears were now those of a donkey and she found her jaw had pushed out, slightly forming a muzzle. She ran her hands down her legs and felt small tufts of brown fur starting to form. She turned around to examine her back. Her ass cheeks had grown to nearly double there size along with her now pitch black anus. Right in the middle of her asss cheeks was a small tail poking out. Then she noticed her groin. She could feel her juices soaking her panties. With her heart racing she dropped her pants and then lowered her panties. Her pussy was swollen to twice its size and was just aching to be touched...
All the while Jen sat watching her friend undress. Jen hadn't forgotten about her raging erection either. She'd foolishly pushed Amber off before she could finish. Oh how she now regretted that decision. As Amber dropped her panties Jen caught a glimpse of her gaping black anus. She was immediately transfixed. The smell of Ambers genitals slowly made its way over to Jen. They infiltrated her new equine nose and set her desires alight. She slowly stood up and against all of her common sense made her way over to her friend.
Jennifer kneeled down behind amber and began sniffing her ass and pussy. "Amber... I have to.. I cant help myself" Jen stuttered in between breaths of her succulent odor. "It's okay. I want this too" Amber replied kneeling down on all fours and presenting her ass to Jenifer.
Wasting no time at all Jennifer stood up and placed her shaft at the tip of Amber's anus and slowly pushed in. Amber moaned in pleasure as the now 10 inch monster invaded her bowels. She felt her insides changing to accommodate the length of her soon to be species' penis. Their bodies elongated taking on a more mule like shape as Jennifer thrust in and out of her partner. Despite the enormous pleassure she was in Amber could feel her vagina changing, her clitoris was become more and more elongated becoming phallic in shape. It continued to grow with each thrust and soon Amber felt two large balls form underneath her new shaft. Along with the change in her groin Amber felt her legs begin to buckle and straighten with the fur covering them becoming more profound. Her petite feet had shrunken into a black cluster in the process of becoming hooves. Amber was not alone in her changes with a similar process being under taken on Jennifer.
Meanwhile Jennifer was reaching her climax. "I'm Cuuuuuummmmiheeee-Hawww!" She brayed loudly as she pulled her friends ass all the way down her shaft and ejected her sperm deep into her bowels. Panting heavily the two friends sat there for a while in a pool of sweat while regaining their energy. Eventually Amber decided to get up. She stood up slowly letting Jen's flaccid cum soaked penis slide out of her anus. It made a loud popping sound when it finally left her ass.
Amber stood with her back to Jen reflecting on her changes. Jen now with a clear head asks amber. "What do we do now? I could use 'Transform or Dare' on you and revert you back to human and then you can do the same for me?
Amber pondered this for a while and then came to a conclusion. "That seems to be the smartest thing to do, however before we do that there is something I need to take care of first" And with that Amber turned around to face Jen revealing her new throbbing penis.
Jennifer smiled and raised her ass, ready to be taken by Amber.
