The doctor stared at his machine in wonder. A camera sat on a tripod to the right of the lab, recording everything.
A fabrication device capable of creating virtually any body part one could think up, sat before him on a stainless steel table in his lab. He was more than just a doctor, he was a scientist. Some, he supposed, would even consider him "Mad" for what he had developed. But today he would show the world just how "Mad" he was.
He pushed the plunger down on the vial, and let its contents empty into the machine from the slot on top. The contents of said vial were DNA samples of a multitude of men and women he had performed simple blood and skin tissue analysis' for at the hospital. As the vial emptied, the machine came to life. Hundreds of lines of code wrote themselves into source material that could be drawn from when the machine was activated.
After it was complete, Doctor Keen went to work. Cracking his knuckles, his fingers flew across the keyboard filling in the missing pieces of code, and applying it to the various parts he wanted to print. After an hour he was satisfied, and put the fabricator to its first run.
It happened faster than he thought. A box to the right of the machine, and attached with cables and tubes, started to get hot as the fabrication was carried out. The temperature gauge read high, but not outside the realm of acceptability; and after a few moments, less time than it would take to air fry yesterday's pizza, the lights faded from the box, and the latch holding the door closed at the front unlocked.
Doctor Keen used a glove to be safe, and lowered the door, as if it were a toaster oven. Inside, was what may, at first glance, looked like a bra. A pair of tits with short tabs extending off on either side. Beyond the tabs however, there was no visible way to wear them. He pulled them free, replacing the heat glove with nitrile gloves.
"Moment of truth." Doctor Keen centered himself in front of the video camera, disrobed, and then took the new printed breasts in his hands, one holding a tab on either side. Then, carefully, he pressed them onto his chest, rubbing the tabs with his thumbs as if that alone would secure them in place.
The sensation was mind blowing. It tickled, and tingled, and yet was extremely pleasurable at the same time. The code he had written, gave what he created instructions once it had bonded with flesh. The DNA encoded within would actually rewrite his own DNA structure, and not just adhere to his skin, but become PART of it! Soon he could feel the skin, the pleasures of the nipples, kneading the flesh as if it was his own, and it felt incredible.
The mould lines stayed present for a couple of hours after adhesion, but soon they were absorbed as the coding finished its work.
Doctor Keen stared at himself in the mirror, shirtless, proudly displaying 36 DDD breasts. He looked back at the machine. The world would know his name. If he had to give cocks to every woman, and tits to every man. His mind began to concoct some truly horrifyingly erotic possibilities. Forgoing a shirt, he sat down again at the machine and began to type again. There was still plenty of DNA serum left to play with, and he had to test the limits of what was truly possible.
