Manhood Exchange (Patreon)

The premise is based on a story I read a while back and forgot to bookmark.

I was in a shopping mall when I got the notification on my phone. Out of habit I just tapped the icon and suddenly I got a large, erect cock filling the phone screen. I immediately became aware of where I was and had a few seconds of panic before reassuring myself that no one else saw it. I moved a few steps to somewhere less open, where no one could walk behind me, and had a look again.

It was beautiful. Massive and uncut, with the skin pulled back to expose the pink, gleaming head. Actually the entire cock glistened like he had made a few strokes with precum on his hand and then positioned himself with just the right lighting to make the veins pop a little extra. The truly remarkable part was however the overlay at the bottom of the screen. "$400, quick trade"

I'd been on the Manhood Exchange app long enough to know a cock like this is usually hundred times that price, if not more. Whatever impression you've got from watching porn, people are on a bell curve with cock sizes, and the ones on the higher end of the scale aren't selling. All the people who used to compensate with a big truck suddenly ended up in the same market, competing for the same cocks, and they make a hell of a lot more big trucks than big cocks. Oddly enough there was a market for really small cocks as well, not quite as high prices, but just as small supply. Normal people like me in the middle of the bell curve with no cash to buy and no cock to sell just had to make do.

It's not enough for a cock to just enter the market either, which itself is a thread to needle with the 18-35 eligible age span and clean health declaration. For you to find one it has to be bio-compatible for science reasons and roughly the same race for ethics reasons, though the latter is just a matter of money. Obviously I tapped the "Deal!" button in the app before I even checked out his profile. With that kind of cock everyone would know you either had a shit ton of money, or you could get it by selling. The profile didn't add much though. Just more good-looking images of him and his cock. A text message function as well, but was there really anything to talk about?

You'd think I'd be a bit more careful swapping cock with another man, especially since you can't swap again until all the cells have been replaced because of some quantum spin entanglement bullshit. Ten years with bad meat is a long wait, but I already knew he was a bio-match and healthy, so it was more Fear Of Missing Out. I had some shit I hope I could fence, so I took an instant online loan and had the whole deal closed before I'd passed Baskin Robbins on the way out. Both I and my normal size cock were excited. 

Just ten minutes later the phone chimed again with a proposed time for the swap at 7:20 pm, almost three hours away. Though I didn't know anything about this less than an hour ago, any delay felt too long, like I hadn't realized how much I wanted this. What it would mean for my position in the crew. Every minute of waiting was a minute where something could derail everything. My phone could be stolen. The exchange could cancel it for some reason. I tapped "Accept" and headed home with the phone in a secure grip in my pocket.

The instructions after I had accepted were straightforward. Be seated with a naked crotch and open the app ten minutes before the scheduled time for exchange. I decided to be pantsless until then just to be safe, and I set three alarms on the phone. One at 6:50 to sit down, if I wasn't already sitting, one at 7:05 to be ready, and one at 7:09 to open the app. I sent a text to Shawn and told him I wouldn't be joining the crew until later, if at all. No details of why.

Then I just sat down in the comfy chair. Three hours to go. I was only wearing my hat, socks, and T-shirt. And my bling of course. The sweatpants and my trunks were in a pile on the floor, and the phone was charging next to me. My cock was pointing almost straight up.

I realized that it would only be my cock for another few hours or so, and I should say goodbye properly. Normally I would jerk off in the shower or in front of the computer, but since I was already perfectly seated and with an erect cock in front of me I just grabbed it and started to remember all the highlights we'd had. When my neighbor Jamar excited came over and wanted to show me something. He was a few years older, but still occasionally spent some time with me. He showed me into the bathroom, lowered his pants, and told me to do the same. Then he showed me that by pulling on his cock he could get it to "bend" in his words. I remembered waking up one early morning with my boxers wet and worried I'd peed my bed. To my surprise they were filled with slime, but just to be safe I put them under the bed to dry so my mother wouldn't know. I remembered that time I got an erection during a movie screening, and slowly wanked but desperately trying to avoid cumming or anyone else noticing what I did.

I remembered the first time I had sex, the first porn I jerked off to, the first time a date ended in sex, the first time I had sex in a car, the first time I jerked off to a porn video on my mobile. All while doing this I tried to go as slow as I could, like at the movie. Flashing before me were dates, partners, and porn stars, while the top of my cock had some frothy pre-cum. I was shocked when the alarm went off. How the fuck could time have moved that fast. I scrambled to get hold of an old T-shirt within reach, and pretty quickly came into it with a few pumps of cum. Not really the satisfying climax I had envisioned.

Suddenly time was moving slowly again, and I was stuck watching dried off, limp cock in front of me. I became self-conscious about how it looked, worried about if the seller would cancel the trade last minute seeing what a lousy deal it was for him. He'd seen my photos already though, but they were taken erect and with good lighting. What was the cancellation policy anyway? The next alarm went off. Why did I even set that one? I was getting nervous. What if it hurt? There was a lot of news about misteleportations some years ago, and this was way more complicated. I didn't even understand how it worked. I knew the basics of standard teleportation from school. Every particle is a probability wave that exists everywhere, but the probability of it actually being at a specific point is overwhelming. By manipulating the quantum state you can poke the probability so that it is more likely to be somewhere else. Just a change in probability, so it can move instantaneously anywhere in the universe, given enough math. Swapping body parts between people was way harder, so it was bound to have lots of issues that could happen.

The last alarm interrupted my train of thought. I kind of felt not ready. Rich people did this, so it should be safe to do I reasoned, and tapped the activation button on the phone.

"This will start a legally binding contract with Manhood Exchange Incorporated adjudicated in the state of Delaware. Please identify yourself." the phone voice said. I pressed the white circle on the screen with my identification finger, the middle one of course.

"Please sign that you are aware that concluding this transaction will replace your penis, testicles, prostate, and relevant connecting tissue, glands, and other structures with a third party as preliminary agreed." I pressed the circle again, wondering what would happen if I didn't. The $400 would certainly be gone.

"Please sign that you are aware that this is a one-time transfer option with Manhood Exchange Incorporated that cannot be reversed through quantum transplantation." I pressed the circle a third time.

"Please sign that you are aware that both set of testicles will be made infertile through this swap." I pressed the circle a fourth time, not so nervous I barely registered what I had signed. The screen of the phone changed to showing a live video from my selfie camera, showing me half-naked in my lounge chair. "Tap to connect" it said on the screen. I did.

The image quickly changed to show the man from the photos lying down in a white, far more upscale couch than I was sitting in. "Yo, man. You ready to do this?" he asked. His erect cock was just as big as it had looked on the photos, almost looking bigger as it was swaying with his breathing. The instructions on the screen said "Verify the other party is the selected exchange party and that he is seated with exposed crotch."

"Yeah, let's do it." I said, and tapped the Verified button on the screen. I could see from his motions that he did the same, and a timer started on the screen, counting down to 7:20. "So, will it fit in speedos?" I blurted out, still feeling nervous and with several minutes to kill. He chuckled. "Shorts are better for swimming, but you want some tight trunks to keep it in place when you're wearing normal clothes. I use compression shorts a lot."

"Well, you can use whatever with mine."

The last 40 seconds we just stared at the countdown in silence. The actual swap was instant, almost silent, though I wouldn't be able to describe the sound, and without any shimmers of light as you can sometimes see when teleporting. It felt like someone spilled warm water over my crotch, though that quickly went away, but it was replaced with the most amazing, intense horny hardon I've ever felt. It was like the cock was buzzing, craving attention. "Enjoy the wank" the other guy said. "What? Oh. Thanks!" I said and the video was closed from his side.

I grabbed the cock with my hand and instantly felt the difference in size. It was almost the size of my wrist. I just moved my hand up and a trickle of precum oozed out and trickled down over my fingers. I leaned back, closed my eyes, and continued where I had left off, thinking about the most recent porn videos, and in not too long I could feel the buildup of a climax, only this time I was unable to force it back. It just kept building and building, and I think I actually moaned out loud as the first rope of cum erupted. Then another one, and another one. Then I had to open my eyes to look at the mess, and it wasn't any small squirts of cum either. It looked almost comical how my T-shirt was completely soaked in cum, and I was still pumping out a few more ropes.

To my amazement the cock was still semi-erect. I got up and hurried to the bathroom and threw the cum-wet T-shirt. After a quick look at my sticky chest I decided to have a shower. I stripped out of the few remaining items I had on and proceeded to have another wank in the shower. This one lasted a bit longer and produced slightly less cum, but it was still a shocking amount.

I had barely dried and put on my underwear before the new cock started to firm up again. I grabbed the phone and sent a text to the seller in the app. "What the hell is happening with my cock? Were you always hard?"

The app sat silent for a few minutes until a response chimed. "It's called hyperspermia. It's a genetic condition, so not a disease in Manhood Exchange's definition. You'll learn to cope several hours between wanks. It was the precum that bothered me the most. Just drink a lot of water, always wear a condom, and compression shorts really help, as I said. Good luck!"
