Aaron stood up choking.
Jack was sitting in Aaron's stomach and feeling the juices trying to eat away at him. He felt them entering him as if through osmosis. He was feeding. His meal caused him to grow. Soon he filled Aaron's entire stomach and started to exit through his bowels and his throat.
Aaron felt something inside of him. He could feel it rising along his throat and poking at his butt. He reached his hand around and stuck a finger in. At first he thought that his butt was flat but as he pushed, it still went in.
Jack was annoyed. He had just been violated in the worst way a man can be violated. Aaron had shoved his finger down his piss slit.
Aaron felt a tingling around his waist. He looked down. His own piss slit had been covered with a film. The tingling continued. His penis grew pale and lost its colour. Now he could see through the shaft. He rubbed it. It felt different...more rubbery than normal. Now he could also see through his fingertips. The tingling spread. He rubbed his shaft, now he could see through his balls. He could see the white liquid churning inside.
The thing inside of him started emerging from his butt, though a layer of skin kept it from emergin. Then it lengthened out his throat. To his horror he saw two balls flop out of his mouth. They grew and grew until they were the size of bean bag chairs. The thing inside him, now reasonably guessed to be a giant penis started thickening. It stretched his jaw to amazing proportions and stretched his abs into large checker squares. Mean while the transparency spread and you could now the the cock inside of him. He looked to Dustin for mercy and noticed that it wasn't the cock that had grown, it was he that had shrunk. Dustin was now a giant in front of him.
Aaron's lip curled around and he stood limp. He was now a latex condom stretched around a detached penis lying on the floor. His arms, legs, and cock retained their original shapes and hung strangely off the side of this giant penis.
