With a hissing sound you see little bumps on the top of Nates head begin to sprout from his hair. Soon pointed ears are inflating out of his skull and moving down the sides of his head to connect with his human ears. They shrink and are engulfed in the plastic donkey ears as Nate changes.
At his back you see a small bump form under his smooth black speedo. It starts to push out and his waistband snaps down to release the expanding tail as it grows out of him.
"Ugh... I feel sick but kind of good too. What happened?" says Nate as he stands up. Squeak goes his tail as he turns around. His eyes wide he reaches back and feels it poking out above his speedo. The inflated shaft of a grey balloon donkey tail, just like the balloon he had a moment ago makes little sounds as he pulls on it. Moving his hands up he explores his new ears too.
"Im turning, like you. Oh god. We have to escape. If we leave the island maybe it will stop." He looks nervous as he speaks and you glance down to see he has an erection pressing the front of his speedo out. Despite the panic, he is aroused. You are too, seeing your friend change. Its appealing to a part of you that you didnt know was in there.
With a little squeak the boy behind the locker bumps against the ceiling. He has totally changed, and much faster than you or Nate. To your surprise you see he can still move. His head turns toward you and looks at your with his shiny plastic face. Its a bit eerie as you know that used to be a person.
There must be a reason. Maybe they had been here longer, maybe it was something in the water. You stop thinking about it as you feel your feet begin to tingle.
"Nate. Keep trying the door. I dont think Im gonna make it. My feet are going." You say to him.
You both look down at the same time. Your feet are shrinking, becoming rounded and shiny as they change. You lean against Nate for support as it is suddenly hard to stand. The ends of your legs are now little rounded balloon hooves and the change is progressing up your legs. Nate is watching and he is rubbing the front of his speedo as you turn, breathing deeply.
Your legs inflate and loose their definition as they change, Your plastic hoof-hand on Nate is all that keeps your balance now. You feel lighter as the change in your hips forces you to bend over. You are on all fours now with your balloon legs holding you up.
