“TEMPORARY ANATOMICAL ADJUSTMENT TESTING. ROOM 881”

I remember that job posting slip - it sounded so *clinical*, but hey, it sounded like more fun than “sanitation assistant needed”. That particular campus had a knack for attracting outside help since they were known for generous payouts to their temporary staff.

And I *do* love a generous payout.

Anyway, I found my way to room 881 and it was a pitifully sized alchemy lab with some of the worst organization I had ever seen, flasks used as paperweights, reams of paper - actual *paper,* not parchment - just laying in piles. And the weirdest thing was the distinct smell of artificial air fresheners covering up what was almost certainly a chemical burn. I went to look at some of the piles, and that’s when I met her. Well, I say ‘met’ but I mean ‘I got yelled at’.

“Absolutely not! Do not touch. Hands to yourself. Everything, except you, is in its proper place.” 

Now this woman is not the kind of person I like to argue with. I’d call her “high-strung” but it doesn’t carry the right weight. ‘Pole-up-ass-disorder’ maybe. She was attractive too, tall, early thirties, auburn hair, and the kind of authoritative vibe you got from one-too-many people telling you that you can’t do something shortly before eating their words. 

In a nutshell? My type.

But hey, I’m here to let the horrors of science fuck me up for a day or two and walk out with a paycheck, not ogle my contractor. So I go to ‘my place’ which she oh-so-helpfully pointed out as a spot on the floor with 2 footprints outlined into it. She was staring at me the whole time with these piercing green eyes. Made me feel like I was in trouble just for breathing her air.

“I am Professor Dales. Paperwork first, then testing, answer quickly please.”

Go for it, Professor.

“Name?”

Caz.

“Weight?”

140-ish, I guess.

“Pre-existing conditions?”

Not that I know of.

“Species?”

Changeling. 

That one got her attention, always does with these contractors. My people may be rare, but I am one-of-a-kind. She arched an eyebrow, and then rattled off the rest of her questions. Boring stuff. She scribbled down the answers and put the clipboard onto one of the paper stacks on the table. She slid a panel out from the table and keyed in a quick sequence and all of the paperwork slipped away in a small flash of light. I wish that’s all it took to clean my room. In its place, two flasks, a new clipboard, and a pen were the only things on an otherwise clean and large oak table. She picked up the clipboard and pen.

“Alright, Caz let’s go over this nightmare.” 

Nightmare?

“Best word for it, now your status as a changeling should make this physically easier, but as for psychological…”

Woah, Professor you’re freaking me out here. 

Sigh, “Look - just. I’ll be blunt here. This contract gets me nothing, I can’t exactly use it for clout, but I was told I was the only one with the chops for this brand of magic. So from your end; how comfortable are you with genital transmutation?”

Genital?

This woman was trying her hardest to keep her composure, no clue how she kept a straight face. She was really cute when flustered.

“Yes. This contract involves the testing of an alchemical solution that will adjust the volume and efficacy of seminal fluid in males, and have an accommodating effect on females. Additionally, due to the nature of this kind of magic as well as the fact it is stamped as an expedited request, testing will have to be done on two, live, human or human-adjacent individuals. Are you comfortable with that?”

Well…damn that’s not what I was expecting but, sure. Like you said, my species might help with overcoming physical difficulties and I know how to be professional when I gotta be.

And I mean, c’mon with a pitch that insane I couldn’t just not. I was seeing this through. Worst case, elaborate setup to getting mugged, and I’ve been mugged before.

“Well….good. I didn’t expect you to be so quick to accept.” Oh there was some judgment there to be sure, “now ideally this would require two subjects, one male and female for each variation of the alchemical effects. But you were the only one to take up the contract.” 

Oh this poor woman. I knew where this was going and she was as red in the face as a lobster. 

“In lieu of a second subject I will fill in. I can trust you, of course, to retain the professionalism you promised?” That was equal parts begging and a threat. Of course I said yes. Attractive woman giving me instructions? I fold like a card. 

“Good. Fine. Yes. Okay. Then follow my instructions. As a changeling, male genitalia of a larger size will be required to easily take notes and record effects, so please accommodate that, remove your trousers and sit on the table. Once I tell you, please drink from the orange flask.

I’m nothing if not a good listener. I closed my eyes and let my body take the shape it needed to. Nothing absurd, but certainly not modest. A soft, pleasant heat focused from my core, down my abdomen and to my loins. I felt my blood pump steadily into the forming organs, swelling gradually. Always loved that feeling. Soon enough, there was a girthy shaft about 8 inches long and the plumbing to match. Perfectly formed, like a picture out of a textbook. Dropped my pants and hopped on the table, and grabbed the orange flask.

All ready here, professor.

“Good, I will be taking the blue flask, while there is technically no change between the batches, keeping them straight will help us make sure equal volumes and….oh fucking whatever. I hate this commission.”

Ooh, that professionalism didn’t last long on her end. Can’t blame her this didn’t exactly sound like a prestigious project. I had more thoughts on that, I’m sure but they were completely banished from me as I saw this woman remove her lab coat and glasses, tying her hair into a bun. And that lab coat had put in some legwork, because madame professor was hiding some impressive assets of her own. Her shirt was buttoned fully and still the cleavage of her ample breasts was on full display. She then proceeded to unbutton it (was she trying to give me a stroke?) so it hung at her sides like a jacket. Her tanned skin showing from her neck down to her waist.

“There. That should help things go quicker. Now drink your solution first, it does not last as long for your genitalia by design.”

I drank mine.

“You should notice the effects quickly. This also acts as a potent aphrodisiac, so as soon as you are erect, we can begin the test. I have my desk’s scryer taking notes automatically to ensure we hit all target points.

She was not lying. That drink tasted like metal and hit me like a smithing hammer. I felt immediate and intense heat and pressure in my newly-formed manhood. Pulsating between the shaft and testicles like every blood vessel there was subjected to an increasing tsunami. The cock I wanted to be a ‘reasonable’ 8 inches swelled to a diamond-hard and twitching 10-inches. I gasped a bit. Okay, maybe it was a moan. She got the hint. 

She drank her solution, and I have never been so turned on by a woman swallowing before. I could see her throat flex as she downed the liquid, with the sound of soft gulps, and it was, in the moment, the most erotic thing I had ever seen. This shit was intense. She finished the flask and gave a long moaning sigh herself.

“Please,” she said, desperately trying to maintain something resembling composure, “let yourself…release, the moment you feel the urge to. It will be more than you are used to. Much more. Do not hold back. I need the…data, of course.” 

Her eyes gleamed with the intent of an animal in heat. Her breath heaved her large breasts against her shirt. I wish I could know what I looked like in that state but I was…well, in a state. She leaned down, and put her lips onto my tip. The feeling was of electricity shooting to my core. She gasped, the vibrations reverberating up the shaft and against my aching loins and testicles, gods they felt so full. I focused on the feeling and she slid her soft lips down my shaft slowly, taking more and more of it. I felt my cock slide down her warm mouth and into her throat as I felt her lips meet the base of the shaft. She took the whole thing. I looked down and couldn’t believe my eyes.

“Mmph….glk.” She was moaning on it, eyes nearly rolled into the back of her head. She had one hand underneath her skirt, clearly playing with herself. I’d take a shot at the professionalism statement, but that potion was something else. I can’t imagine anyone keeping themselves still after drinking that. Her throat had stretched around my newly swollen cock, making a subtle outline of it as it smoothly slid up and down her neck. The pressure built and built in my testicles as she bobbed, gagging and moaning uncontrollably, they felt like they could burst. Her fiery orange hair swayed and tossed as she moved. A fresh shock of pleasure fired up my spine as I felt her tongue flex around the base of the shaft and she greedily sucked.

Her head swayed up and down, my cock twitching against her tightly stretched throat as she grunted and gagged, a soft wet sound betrayed the actions of her right hand, as she groped herself with her left. Saliva and precum coated my shaft and her face in equal measure, her eyes watered, despite the look of pure carnal hunger that burned in them. The composed and embarrassed Professor Dales was gone, replaced by a hungry beast, set on draining my body of all of its sexual essence. Keeping my hands to myself was a herculean task, but one I did not have to focus on for long, as she slid almost off my cock entirely, until just her lips were pressed over the sensitive tip-

-And slammed back down, fully hilting the 10 inch monster of our own creation.

That was it, I could not hold back. My lower back and groin all tensed at once as I couldn’t hold back the floodgates any longer. I bucked my hips into her face involuntarily and I felt my already engorged manhood swell to yet another notch in girth as I felt a hot stream - no, jet of thick cum erupt down her throat. I vaguely remember hearing her swallow, and swallow, and swallow as if chugging a keg. It was at that moment of incredible ecstasy, I blacked out. It must have only been for a moment as I woke up to the sound of Professor Dales panting and moaning in the aftershock of her own orgasm. My vision slowly unblurred and I looked down in shock.

The Professor sat on the floor panting, drool and cum leaking out the corner of her mouth, dribbling onto her chest. Her already sizeable breasts were lifted up further by her now incredibly swollen stomach, looking as if she was full-term pregnant with twins. Her shirt hung off of one shoulder, soaked with sweat. Her skirt was almost missing beneath her stretched gut. She looked up at me.

“I….ahh…help me up, please.” Her previously judgmental and piercing eyes were pleading now. I would never let someone in need down. I helped her to her feet, as I heard what must have been gallons of cum sloshed around in her soft stomach.

It was the best sound I have ever heard.

The professor propped herself up against the table and caught her breath as best as she could. She massaged her distended stomach, as it churned through the enormous meal. She slowly turned her head to me and sighed between breaths.

“Test…complete, exactly as expected. Thank you…Caz.”

And that was the start to the weirdest - and one of the best - weeks of my life.
