Controlled Weight Gain

Chapter 1

Listen to this chapter - just press play:
I had finally done it, after years of research, countless nights alone in a lab, I had finally created a serum that would cause weight gain, a programmable weight gain; controlled, it could change a persons body shape and weight distribution, it was exactly what my wife and me had dreamed of, she wanted to be fat but she always had a high metabolism, this, it would blow her up, make her plus size, obese, sexy beyond words. I had tested it out on a colleague during the week, a controlled gain of 35 pounds all to her ass, to say she had a massive ass afterwards was an understatement, a slim waist and a large smooth round ass, Friday she split the seams on her jeans as her ass made the final push of 7 pounds, every ass man in the lab was drawn to her.

Tonight I would give my wife the full dose but with a controlled reaction, her clothing would determine if she plumped up a bit or if she would blow out of her clothes and more than triple her weight. She would not know I gave it to her until her body started to fatten to the point her clothes constrained her, at that point she’d know I gave her the dose and would have to decide if she really truly wanted to be plus size.

Rewind 5 years ago…

I had always loved science and biology, chemicals, etc, for me it was fun, make this and that and occasionally blow shit up, I guess that’s as the fun thing, making stuff that when boom. I was a fun nerd, while I studied my ass off and still had fun, I got the girls, went to parties and in general wasn’t your typical nerd guy. I remember this one year, I went to a frat party with some friends, it was a look into college life and the party scene, I’ll never forget, this woman just caught my eye and I couldn’t stop staring. She was around 5’6”, brunette hair and I’d have pegged her at 200 pounds, curves overflowing in all the right places and a cute little double belly. She caught me staring and with such speed and grace she was on my like white on bread and before I knew it she was naked on top of me and my hands all over her body. I had sensed in my other relationships that skinny was not for me and with this beauty on top of me it was confirmed. I was a chubby chaser.

So forward a year, it’s the end of freshman year, I had flirted and had multiple one night stands with this woman. She knew I loved her body and as such a result it seemed only to get bigger and bigger. She had a pear shaped body with nice sized boobs, by the end of freshman year she had grown, 250-275? I want sure, but her belly had kept up with her growing ass and finally was the front central attention rather than her breasts. She had developed a large double belly, it covered her pussy when she was sitting and for sure when she was standing. Her thighs and ass exploded in size and she confided in me that her size 26/28 pants where now right on her. Throw in the juicy thick arms, the cute double chin, she was an amazing sight to be seen.

So things where good, I was acing all my tests, it was almost the end of my freshman year when one day she showed up and said that it was time for her to leave me, the sex was good, she really liked me, but she had discovered that she had a heart condition and that she had to get skinny and remain skinny, she knew I wanted her to be as she was or bigger and she just didn’t want the guilt. A kick in the gut, I really liked this girl. I managed to get her to let me weigh her and take down her clothing sizes and measure her I also took a blood sample. With one final request we stripped naked and had one more round of passionate sex, Amanda truly was a goddess, before she left I snapped a few pictures of her naked form and then she was gone.

It took a while to get over her, I saw her around the campus, and every time she was skinnier and skinnier, until one day she was down below the size I met her at and dating some jock, I guess she just had to get me out of her mind also? Me I didn’t see anyone for well over 6 months, I did stoke up a relationship with a cute blonde, her name was Jessica, she was the opposite of Amanda, same height, nice boobs but that was it, she was a cheerleader, but also very smart, I think we kicked it off because we had similar mindsets on science. I’d say 6 months later we decided to date each other, she knew I had dated a plus size girl before her, but didn’t know what she looked like or anything else. I remember one day coming back from class to her sitting on the couch with a folder titled Amanda, my heart about kept out of my chest and no words would come, pure panic across my face. She smiled at me, giggled and put it down and got up and walked towards me. She put her arms around my neck and said so that was your ex, she was a real stunner, I bet you miss having all that blubber and weight on you, the softness surrounding your body, the fact that you couldn’t reach around her. “ nodding numbly I couldn’t help but agree, I didn’t know it, but I had become extremely erect as she described Amanda’s body to me, with a swift motion my pants where undone and Jessica was on her knees sucking me, I didn’t last long and collapsed onto the sofa behind me. She got up and said, well you really are a chubby chaser, it’s a shame that I can’t look like her of her bigger than her, my body won’t let that happen, it’d be so cool if I knew someone who could create a serum or sorts to make me that size or bigger.

My mind finally catching onto what she is saying and the gears grinding together a massive light bulb went off in my head, she realized I had caught on and said, I want you to make it, I want you to create a serum that will destroy my metabolism and blow me up like a fat water balloon, I’ve always wanted to be fat, and I know you’ll figure it out and make it happen. So our plan was set, I had a goal, up until this point I hadn’t made the connection to use my knowledge and studies to push for my own personal desires. Over the next couple years I dove deeper into the pharmaceutical parts of my studies, biology, DNA make up and anything else I could that would push me in the right direction to make a serum we both wanted.

After graduation we married, we had great sex, played out fantasies and enjoyed life, I got on at a top research and development company and made strides to unlock the human genetic code to allow body modifications via chemical alteration. I kept my personal projects on a separate flash drive and all my samples separate and secret from my colleagues and boss. This would be a massive money maker for this company and myself and I didn’t want it exposed before I could go to them and show them a positive test result.

It took several years of trial and error but one might I cracked the cell of my wife’s DNA( I used her DNA for most of my research) I was able to identify code and instructions for the body, I knew there where lots of compounds and chemicals out there that could tell the body your not hungry or to store fat as energy etc, with this I didn’t need that, but I needed something I could introduce as a command line for the cell, what it needed to do, what it’s instructions where, was it to duplicate or latch onto another cell and change a certain aspect. I decided that I needed just to really be able to control it without the use of compounds, so I kept digging and decided that some sort of nano tech or such was the answer to overwrite the basic code. So with a tweak here and a tweak there I made a single use nano bot that would fuse itself with the cell and write the code onto it I needed.
