My one-hundred and ninety-second caption, featuring a very clumsy scientist who exposes himself to an experimental fertility formula… after all, I needed to do at least one pregnancy cap for March.

“My my, he’s kicking a lot today~” You cooed, gently rubbing your swollen, pregnant belly with a smile on your face. You loved this feeling, having surrendered yourself to it over the last few months as you savored the fact that you would soon be the proud mother of a baby boy.
Things hadn’t always been like this, of course. Ten months ago, you had been working on a new fertility formula for your pharmaceutical company. Before that day, your hair was shorter, you wore men’s clothing, and the thought of wearing a bra had never even occurred to you. You also hadn’t been very popular with your co-workers or your boss, having a bit of an “ego problem” as they described it to you. You had been in the lab, transporting the latest sample of the formula to be tested on lab rats. In a tale as old as time itself, you accidentally knocked it over and shattered its storage container, exposing yourself to the formula. Calling it a “formula” was a bit misleading though, given how most of it was based off of a genetically-modified version of the Measles virus. You were fully exposed in just a few seconds.
The transformation from a man into a woman was unexpected, and rapid. The modified virus had none of its “traditional” effects, instead rapidly swapping your chromosomes to become female, leaving no strand of DNA in your body untouched. You would have expected such a transformation to be painful, but each pop from your skeleton and shift in your body filled you with unimaginable, pleasurable warmth. Those feelings only got stronger as your more… outwards female features developed, causing your pants to rip apart as your ass expanded, and your shirt to explode outwards as two F-cup breasts forced their way through. You moaned like an animal in heat as your manhood receded, giving you an aching, needy vagina. Your hair was so soft and smooth that your lengthening hair tickled your neck and shoulders.
The whole ordeal had only taken two minutes, leaving you feverishly hot and covered in sweat. You moaned as you writhed on the floor, your new nerve endings all being stimulated at the same time. It was all-encompassing, a full-body orgasm that surpassed anything else. The sensations were so powerful that you didn’t even notice the emergency containment alarm blaring just a few feet away from you. The section of the facility you had been inside of automatically sealed once it detected the breach, leaving you alone with your own new “devices”. Hours later, you had finally pleasured yourself enough to form a coherent thought, practically peeling your soaked, sweaty body off of the floor. Your brain was still swimming in estrogen and other powerful hormones, leaving only one thought in your head: you wanted to be bred. To be impregnated, knocked up, filled with baby batter. Fucked. The slit between your legs burned with a primal desire unlike anything else. Unfortunately, the next few hours were spent being studied by your “colleagues” as they tried to determine what exactly the fertility formula had done to you. According to several of your female colleagues, your male counterparts had been quite… distracted by your primal display. Still, it was eventually ruled that the formula hadn’t remained viable in open air, breaking down in less than an hour, and inside your own body, it had become bound and locked into your DNA. It seemed there was no reversing the changes… not that you really cared anymore.
The company decided the best course of action was to give you specialized quarters on their property, and test your “changes”. It didn’t take a scientist to realize how revolutionary this transformation was, and you and everyone else was curious as to how “far” this treatment went. They were nice enough to give you some input, allowing you to select a “test subject” of your choosing to fulfill your carnal desires. All were volunteers from the staff, and had to be male, of course. Despite your previous status as a man, you had no hang-ups at all with the idea of sleeping with a man, the formula having seemingly flicked all the switches in your brain to the opposite direction. You eventually settled on Dr. Rodriguez, a shy man who you were surprised to see on the list. Something about him in particular stuck out to you, and you wanted it.
Dr. Rodriguez was quite sweet, but clearly intimidated by you. You found this attitude somehow made him even more attractive in your eyes, and you wasted no time “taking the lead”. Truth be told, your pussy practically ached with desire, wanting him to bend you over and treat you like the women you had become, but you were able to rein it in, being sweet and charming with him in such a way to calm him down. You discovered that he was actually packing a monster cock in his pants, and finally getting to feel it in your hands only made you hungrier. Finally gaining some confidence, he finally took charge and stuck it in you for the first time, causing you to scream out in ecstasy as he took your virginity from you, finally giving you what your heart desired. He painted your insides white, and you knew you had a baby on the way.
“I’m so glad I could do something like this.” Rodriguez smiled warmly, rubbing your swollen, pregnant belly. “I love you so much.”
“We’re going to be a big, happy family, my dear.” I replied, leaning forward and kissing his head as he put his ear up to my belly to listen. You couldn’t help but smile, showered in his affection. “I want at least a dozen, and I don’t think you’ll have any trouble doing that~”
You giggled as Rodriguez gulped nervously at your comment, hoping he was really up to the task you had laid out before him…
