Jeff was looking at his nozzle crotch as a thought crossed his mind. What if he shifted more with the toy. Unfolding it carefully on his bed he got a better look at the deflated toy, which was a rubber dolphin that currently had his dick attached to it. Mentally Jeff was already making planned transplants for him to change with the toy before going to the chronovac and typing in his changes. He set the timer for the changes to take five minutes and last a week before Jeff ran out to the pool, butt naked before jumping into the pool, causing a splash as he resurfaced, floating in the water naked as the cool clear liquid passed over his nozzle, giving all sorts of pleasureable sensations as Jeff floated in the water.
But as he was floating there he started to shrink slightly, so that he would be better proportioned for the changes to come. Once Jeff was only about two feet tall, he was floating in the water, unable to touch the bottom as he looked down at his legs. Under the water he watched as they slowly stuck together, turning grey and rubbery as his feet turned into the tail of the dolphin toy, fully inflated as next tail shot to the top of the water, floating thanks to being full of air and forcing Jeff onto his stomach in the poop as he grunted, his back bone extending into a rubber inflated fin on his back that was grey. But then his arms started to shrink. Jeff slowly curling them inward before they turned into the rubber flippers of the dolphin toy. Now Jeff had the limbs of the toy and it's old nozzle. But the changes weren't done as Jeff floated in the water slowly, the rest of him emptying out to become air filled as the now inflable Jeff floated in the pool without a care in the world, part dolphin toy.
