DING DONG!
The doorbell sent out a very loud attention grabbing chime.
"Wonder who that is?" said Jim looking up toward the door to their room. His face was looking more rabbit like as his cartoony inflated features took shape, his ears were smooth and shiny jutting from the sides of his head, his chest had a white ring on it offset from the grey ton the rest of his body was assuming. He pushed Alice gently away from him.
"Im going to get the door. I think we could use more people here in the mix eh?" he bent down and slowly pulled his speedo up his legs, it stretched as he tugged it up over his inflated dick which mashed to the side a little painfully. He decided it best to let his tail stick out behind him.
"Awe honey. I dont know. Im already getting all stiff. What if you come back and I cant play with you anymore?" Alice whined at him. Sure enough she was totally transformed and was having a hard time moving. Soon she would just another inanimate pool toy laying on the floor like the rest of the party guests.
"I'll hurry back foxy." Jim grinned and his large buck teeth stuck out causing Alice to giggle at his silly appearance. He would be done inflating soon too, he could already feel his fingers melting together in to mitten-like pool toy hands as they turned in to vinyl and inflated slightly.
Opening their bedroom door Jim glanced outside as he walked through the living room. The large sliding glass door leading outside showed him the state of the pool party to this point. Almost everybody was transformed in to an inflated animal of one shape or another. Some people were still changing, but most were done, laying on the ground or floating gently in the pool.
Jim reached the front door and fumbled a minute trying to get a grip on the knob with his slick hands.
"Jusht a minute" he said. It was getting hard to talk with his rabbit teeth getting in the way, his face felt tight too, it was probably mostly rubber by now he realized.
Opening the door he stepped back to allow the new guests to enter.
