"I don't want to pick any. They all sound horrible, but I hate myself for saying this, but if I have to be one
of these six things, I know I want to be your PA"
"Whoa, seriously? I just kinda put that there as a joke!"
"Hey it's your own damn fault. It so happens I've always thought they were kinda cool. I was wondering if I should get one, but now I'll get to see what it looks like first... sort of" Jeff pressed a button on the keyboard. A strange sensation washed over him, he got up and walked towards his brother, then knelt down in from of him, staring at his crotch"
"Um.... well.. this is a bit weird."
Jeff gulped, "You're telling me" Jeff's hands were being compelled to move. He reached up and undid his brothers shorts, then slid down his boxers, Jeremy's cock bounced out, half hard. Jeff's eyes were half glazed over as soon as he saw the cock.
Jeremy's cockhead was rapidly swelling, taking on freakish proportions. Jeremy looked down at his massive cock that was as wide as his whole body. His urethra bobbing before Jeff's head like a fleshy pipe.
"Here goes", Jeff's voice echoed slightly as his head was compelled inside. Jeff climbed into Jeremy's Cock until he was up to his mid section. His arms were pulled back against his sides as they started to smooth over. Jeff pushed his head into the bottom of Jeremy's cock trying to pierce through to the outside.
"SHIT SHIT SHIT SHIT! FUCK MAN THIS HURTS!"
With the last few moments of use of his hands, Jeff grabbed Jeremy's legs and pulled himself in one last time with a mighty thrust, his head popping out the bottom. Now that Jeff could see again he could see he was starting to take on a chrome color and his legs had fused into one piece, but still discernible as legs.
Jeremy's cock and Jeff inside it, began to shrink back down to normal sizes. As Jeff was pulled up off the ground he noticed his feet were curving back towards his face. Curious he stuck out his tongue to taste the bottom of his near-chrome feet. It didn't taste like much but it felt right. Jeff felt his mouth stretch wide open and he pulled his feet inside his mouth. He tickled his feet a bit with his tongue and sucked them down. He felt his feet latch inside his throat and was suddenly unable to move anymore.
Jeff was completely chrome now and just barely larger than a standard PA. The pain stopped once the transformation was complete. Jeremy walked over to the mirror and propped up his penis to look. Jeff had indeed become a PA, but instead of shapeless metal, he had formed into a smooth but still recognizable stable of his larger self, except rounded and endlessly sucking on his own feet.
Jeremy ran his finger over Jeff's chrome body causing Jeff to moan with pleasure. Not that Jeff could really move, it was just more of a low sensual vibration coming from his whole body. Jeremy gasped at the sudden pleasure. "Did you feel that bro?" A second vibration seemed to confirm that Jeff could still feel and somewhat respond. "You feel super awesome inside me bro", Jeremy started running his finger all over Jeff's body again, causing Jeff to vibrate continuously. The longer Jeremy kept rubbing Jeff, the stronger the vibrations got. Soon Jeremy couldn't take it anymore and shot his load all over the mirror.
Cum was dribbling down through the hole Jeff had made and was coating Jeff's whole body, pooling in the crevice that used to be his butt crack. "I gotta say bro, you look pretty hot down there, and Fuck. You're going to feel awesome during sex. I think I may keep you like this for a little while"
Jeff tried to call out asking to be turned back right away, but all it did was vibrate more causing Jeremy to come again. "Ohhh fuck yeah. Definitely keeping you" Jeremy smiled at his Jeff PA the walked away from the mirror.
