Josephs friend aimed the gun at Joseph's crotch and before his friend could do or say anything, he had pulled the trigger.
Instantly, Joseph began to writhe around clutching his crotch as if he had been kicked in the nuts.
"Oh fuck!" he screamed, "What the fuck is happening?! It feels like my dick is on fire!"
Joseph developed a massive boner which pitched the biggest tent in if pants but it did stop growing. His erection was pressed so hard into the fabric of his pants that it was chaffing and he didn't know what else to do. Joseph, hobbled to the bathroom as quick as he could with his still growing boner poking straight out in his pants, his friend close behind.
"Dude, does this gun give you a huge cock or something?" His friend asked examining the gun closely.
Joesph had already almost torn his pants off to see an 18 inch penis hard as a rock and still growing sticking out of his underwear. Suddenly Joseph screamed and the penis fell off. It was still growing as it lay on the floor even though it was not attached to his body any more. The sides of the penis began to bulge an to the two boy's horror arms budded from the sides and the root of the penis split into tiny legs. The penis was growning faster and fatter than ever now. It looked more like a giant sausage than a penis. Two small dots appeared on the head near the slit and as the boys watched, a face started to immerge pointing straight up at the ceiling. The penis bent and there were cracking noises as bones developed. It was now three feet long and nearly a foot around. The arms and legs became more articulate and the middle began to draw in on itself turning into a waist and an hour glass form. The foreskin suddenly grew longer and softer becoming baggy and semitransparent and slowly turned into hair. The penis person clutched at it's chest and breasts began to develop.
The penis began to flop around on the grond as the changes completed. Suddenly it gasped for breath, it's fingers now with longish fingers scrabbled at the linolium of the floor. It was no longer a penis, but a woman, shuddering and gasping for breath. She looked up at the boys desperately. She looked like a female version of Joseph, her hair was short and she had smallish breasts.
It is hard to say which was more shocked, the girl, the friend, or Joseph. Joseph stared at the girl in disbelief, his penis had just turned into a woman, reaching down his boxers, Joseph could feel his balls but there was only smooth skin where his penis had been.
"Holy shit dude." Joseph's friend breathed to himself.
