Doug made his way to where the pizza boy was sitting on the sofa. Doug's dough body making slight squishing noises as he moved. The pizza boy sat helpless on the sofa, still a beer keg with small stubs of arms and legs. Doug climbed up next to to the pizza boy.
"Well you got us into a fine mess didn't you?" Doug said to the pizza boy keg. The face painted on the side was moving, its mouth making words but no sound escaping.
"Hang on I can't hear you, but I think an orgasm will accelerate the changes" Doug said looking up at the cock-shaped handle on the pump. Doug grabbed the handle and started to stroke the cock portion of it. "Is this working for you?" Doug asked hopefully.
The Pizza Boy shook his head no and made a pumping motion with his arm. "Oh so I need to pump you?" The Pizza Boy replied by vigorously nodding his head. Doug tried to pump it from where he was but realized he wasn't strong enough to move it, so he climbed on top of Pizza Boy's keg body.
Using what weight he could, Doug was able to pump Pizza Boy's cock a few times and build the pressure up inside him. Doug realized that in order for the Pizza Boy to shoot, he'd have to open his nozzle. Doug quickly climbed down from the top of the keg and made his way to the nozzle. The pizza boy's face a mix of pleasure and frustration.
Doug picked up Pizza Boy's nozzle, pointing it away from the sofa and pushed the button, causing frothy beer to come rocketing out of it. After a moment the stream trickled and Doug released the button to see if it worked. There was some metallic creaking as the keg changed shape some.
The painted face disappeared off the side as a head formed on top of the keg behind the pump, Pizza Boy's face appeared on it, still looking painted on, but there was a little definition to where his features were. His arms and legs grew in size, while his keg body lost some size and girth. By the time he was done, the pizza boy had black rubbery arms and legs, a barrel shaped body that looked like a skinny keg, and a head on top, behind the pump for the keg, the handle still looking like his cock.
"Finally" breathed the pizza boy "I thought I'd get stuck that way."
"Well it wore off some, and it seems when we cum we change back some. But lets get out of here before someone sees us." Doug climbs down off the sofa and helps the pizza boy down, they quickly head for the bedrooms hoping nobody catches them along the way.
