"a penis." Jeff said with laughter.
"A what!" Yelled Dean, his eyes going wide. "you have to stop the change!"
"Dude, I can't. The change can't be stopped once it has already started. You've already been hit by the beam. I guess you just gotta accept being a real dick for a while" Jeff began to snicker again.
Dean wanted to punch Jeff in the face. He probably would have too if he hadn't suddenly felt a strange and powerful urge to strip. With growing fear, Dean began pulling his clothes off. When he reached his boxers, he tried to fight the urges, but it was no use. Dean reluctantly pulled them down and now stood naked in front of his friend.
Dean looked like he wanted to say something but instead he spun around and bent over Jeff's bed, lifting his ass up into the air. He tried to move away, but some strange force was keeping him pinned against the bed.
Jeff wondered what was going on and then he was hit with a sudden and overwhelming desire to fuck Dean in the ass. Jeff pulled his pants and boxers down, freeing his rock-hard 7 inch cock. Jeff wasn't gay, but he couldn't deny the intense desire he was suddenly feeling for Dean. His mind was telling him that nothing would feel better than having Dean's asshole tight around his cock.
Jeff strode over to Dean and grabbed the sides of his friend's butt cheeks before plunging his cock into Dean's ass. Surprisingly, he entered quite easily and Dean slipped over his cock all the way down to the base with ease. Almost immediately, an intense warmth radiated from Jeff's groin and from Dean's butt making both boys moan. Dean's backside fused with Jeff's groin area and Jeff could suddenly feel Dean like he was now a part of him.
"Oh, looks like you are going to be MY penis!" Jeff said while patting Dean's back. He could feel the pat and it felt ... good. Almost like patting his own cock.
"No!!" Dean yelled being pulled out of his previous stupor. "I don't want to be your dick!" Dean tried to pull away but was completely attached to Jeff. The more he struggled, the more pleasure it seemed to give Jeff. Now, Dean was noticing the transformation was speeding up for him. He shrank back against his friend as his arms sunk back against his body and his body hair fell out. His legs were pulling up into his body as well, as his backbone and other bones melted away while the rest of his body took on a tubular shape. He was now maybe only 2 feet long as Jeff held up his body with his hands.
Dean moaned as his head and neck area flared out a bit forming a mushroom shape. His whole body and especially his head region was becoming so sensitive as Jeff stroked him. He had never before felt such intense pleasure all over his body. His face began to shift as his eyes, nose, and ears disappeared. His organs vanished as Jeff's urethra connected to his mouth. Dean had now shrunk to about 8 inches long as Jeff continued to stroke him. The pleasure became too much for Dean as he opened his mouth into an 'O' and moaned loudly. His mouth then moved up to the tip of the mushroom head and began ejaculating cum.
The chronivac dinged signaling the end of the change. Jeff stood there holding his former friend in his hand after experiencing an intense orgasm. Dean was starting to soften. "Well buddy. We are certainly going to have an interesting week..."
