As Blake filled the rubber doll with air it looked more and more like his brother.
What did that sick fucker do to be the model for this sex doll. Blake laughed to himself.
Well I hope he got plenty of green for it.
As he got it pumped up it looked nice and firm. Chad felt like he was back to normal but was still unable to move.
It was when his brother for the first time put Chad on the bed and fucked the shit out of the rubber doll that he realized how much he loved dumping a load in this rubber sex doll.
As he pumped his 6th load inside the doll he got tired and fell asleep. When he woke he found he was still laying on the sex doll and he grew hard again. It was his 7th time when he felt his bladder had filled and he needed to relieve himself. He had thought about getting up and going to the bathroom but then he though he might as well just dump it in this sex doll.
He giggled as he peed a long hot stream inside the doll.
But as he picked up the doll he noticed that it looked a little bloated and the sperm and pee wasn't coming out he lifted it up and looked for a relief valve. There was no identifiable valve to release the pee and cum but he noticed that he could deflate the rubber doll by putting the inflator needle inside Chad's cock and releasing some air till it was the right size again. He noticed that when the liquid came near the penis the air would stop flowing. He would hopefully find a way to release the other later.
It was six months of using the sex doll for a full time urinal and cum dump when he could no longer release any air trapped in the sex doll. The next six months found Chad being filled more and more and when Blake was done with him for that night he would put him in the corner like a bloated rubber Buddha sitting there with a goofy look on it's face.
When Blake got tired of his sex doll he brought it to the frat house to use. He heard they were having a party and as he dumped the filled sex doll in the wheel barrow it sloshed around.
He brought it to the back of the house where he found some guys that took it down to the basement and a line of men lined up to use it.
About midnight when Rick returned home and found the line he was ready for his turn when he realized what it was and laughed so hard. He went back upstairs and found how to reverse this transformation and in the morning Chad was once again human. A particularly round human but human. And he was so addicted to cum and piss it was almost as if Rick didn't need to change him back. But at least now he would be able to metabolize the cum and piss and get rid of some of it but he wobbled as he walked with what was in him when he changed back. He must have been more than 800 pounds but at least he was able to get around although quite slowly.
