Eric began to feel very... odd. He couldn't describe it. Then felt himself shrinking.
“Hey, I thought you were the one going to change?” he said confused.
“Oh, I am. Just you wait and see. I chose this because it was a fetish I'd never even thought of before I saw this amusing illustration under your 'I wish' folder.” Eric tried to remember what it was he'd saved there. That was an old folder he hadn't touched in ages full of weird stuff he found bizarrely interesting. Though he didn't know if he actually wanted to experience all of that. But which one had Lisa chosen?
He saw his arms and legs receding into his own body, which made him start to panic. His hair was shrinking back from his face and he wondered if he was growing bauld. What kind of a fetish had she found!? “Lisa, I don't think...”
“Hush hush. You'll be safe. And if I don't like it, I can always change you again.”
“Lisa. Not all fantasies argh...” Eric failed to speak anymore as his throat began to swell. Or at least not shrink as much as the rest of his body. How small was he going to become!? What was he turning into!? His head leaned back and all of a sudden, he felt all his bones melt away. It wasn't an unpleasant feeling, but it was the strangest sensation he'd ever felt.
He lay on his stomach. 12 cm long. A meaty cylinder with his own face at one end. Limp and without the ability to move or make a sound. Now he realized what he had become. Just as the bizarre and frightening realization hit him he was picked up by his girlfriend and held against her crotch where he joined to her seamlessly. He was her penis! Or rather, his penis.
“Oh my god! We look perfect!” Lisa exclaimed in a different pitch voice than he'd heard from Lisa before. She or he ran over to the full length mirror on wardrobe. Eric slapped against Lisa's tries with every step. Lisa stood admiring himself in the mirror, but all Eric could see was the floor swaying beneath him.
Lisa lifted his head up so he was pointed at the mirror. Lisa was a guy now. A rather cute guy that somehow still looked like Lisa. Despite it all, Eric found it quite arousing. The feeling spread through his whole body rapidly as his blood pressure increased making him grow and stiffen. It was a hornyness he'd never experienced before. His entire body was an erect cock and the cock pulsed with a need to be touched. He was now staring directly up at his girlfriend. No. Owner.
“I think I'll go by Levi for now,” Lisa said. Had Eric been able to, he would have begged his owner to stroke his body, but Levi seemed content to tease him a little first.
“I told you you'd like it,” he said, gently running a hand up and down Eric's underside. Eric felt a flush flow over him and then a peculiar taste fill his mouth. Instantly, he tried to hold it down, but the precum bubbled forth unstoppable. He couldn't keep it in. It filled his mouth and slowly gushed out.
“Oh! You're this excited?” He felt like he was drowning in the precum, but of course he didn't breath anymore. Levi used his thumb to rub it all over Eric's face. They both shivered at the sensation. “Oh wow! This feels amazing! Keep being such a good dick and I might never want to turn you back.” The threat both thrilled Eric with a forbidden lust, but also frightened him to the core. Yet all he could do was experience. He couldn't even communicate with more than his facial expressions, which were no doubt orgasmic at the moment.
Levi leaned forward and with amazing flexibility, pulled Eric into his mouth. Blowjobs were one thing. Self filacio was another. But this! Oh god! Eric couldn't discribe it. It was like kissing, getting a blowjob, having all of himself stimulated at once and drowning in precum all at the same time. All while being totally humiliated and helpless. It was the most wonderful and tormenting feeling he'd ever known.
Levi broke the blowjob kiss for a moment to smile wickedly at the penis.
“You know, I didn't just change us. I made it so that the boy Eric evidently never existed. No one remembers you but me. And no one will be that shocked that my penis has a face. If I show anyone that is. I could change you back, you know. I know it excites you that you might stay this way forever.” Levi laughed. “But I'll be fear and give you this one chance to let me know if you want to return to your former self. If you go flaccid within the next minute, I'll change you back. But if you remain erect, I know that you want to stay this way. Even if you don't consciously know it yet.”
Levi pulled out his phone and set the one minute timer. Eric did his best to stop being so horny, but he just couldn't. He tried forcing himself down, but he had no control over his new form. As if anyone could control their dick when this stimulated. The full minute ticked by and Eric didn't even manage to stop drooling precum. The humiliating taste of it drove him wild.
“I'm so glad you decided to be my cock from now on.” Levi said, grinning. But now that I've fulfilled one of your fantasies, I think it's only fair that you fulfill one of mine. Levi returned to the computer and began typing. From bellow the desk, Eric couldn't see anything. Fear and excitement battled within him.
