Author's note: this story has lots of kinky sex. It's also fantasy. Watermelon sized breasts that produce gallons of aphrodisiac milk simply do not exist, and there are sex scenes in here that would frankly be incredibly painful if they were to occur in reality, but are a regular part of much fantasy erotica. So I advise you to suspend your disbelief, and if breast enlargement, bondage, milking, futanari, huge cocks, tiny cocks, alien sex, alien impregnation, massive semen production, gang bangs, triple penetration and tentacle sex is not your thing, then read no further. Cheers!

Tonight was the night. I'd found the right mistress to help me perform the operation. The price was one I was more than willing to pay as well; willing submissive servitude and twice daily milkings of my new assets for 3 months. I would have my breasts enhanced. They're already a lovely C-cup, and I've been working them with suction cups and massages. My nipples are like long erasers now, pink and pointy and I could sometimes even squeeze a few drops of milk from them. With the enhancement, there's no telling how large my boobs would become as they filled with what I hoped would be cups of genetically modified, aphrodisiac milk. It seemed like the process created different results for each woman.
I'd been following some of my favorite celebrities--called milk-maids-- and they develop mammaries from a D-cup to water-melon sizes. Their pillowy mounds could produce up to a gallon of milk a day, more if they were being sexually stimulated. So of course they were. It was a lucrative career, as not only could the milk produced be sold at a premium but men and down both paid to have sex with them. All humans, of course. Interspecies sex wasn't forbidden except for with milkmaids, as the aphrodisiac effects were mild on humans, but could cause adverse reactions in other extra-planetary species.
My new mistress, one of the rare natural futa that had started being born with increasing regularity in past couple centuries, is a renowned researcher in various sexual modifications. She has a new serum she's been experimenting with and now she is exploring administering it in various ways. I'm test subject number 4, codename kitten.
......
I waited on a kneeling cushion in the corner of my mistress's dungeon room. The floors were bamboo wood scattered with cushions around the various props set up in the corners and by the walls. There were 3 or 4 people going about various quiet activities. I wanted to look, but after I'd been led to the cushion I'd been instructed to keep my eyes lowered. I was naked, my arms folded behind my back and my nipples hard and pointing from my round breasts. My shaven mound was already soaked from the anticipation I'd been feeling all day. I was afraid I'd start dripping on the lovely red silk beneath me at any moment.
A pair of shiny black heels stopped in front of me. My mistress. I recognized them from earlier. A crop under my chin lifted my face to look at her. My eyes raised, taking in her pin striped pencil skirt and deep blue blouse. She'd also added a lab coat, opened and flowing around her to her knees.
"Lovely!" she exclaimed, as I met her dark eyes set in a chiseled face. "You'll be a perfect first test candidate for my new theory. Good proportions- slender waist, large buttocks, average boobs. And such a pretty face, with those big blue eyes...a shame your matching hair had to be shorn. A legacy of your mother's? A renowned courtesan in her time. Well it would have fallen out during the procedure, but it will grow back in about a month. Come now, up! I'm eager to get started."
With that she tapped me on the buttock with her crop, using it to steer me across the room to the contraption that stood in the middle of the floor. My eyes puzzled over it. On a slightly elevated platform there was a box made of steel rods to support various straps. There on the floor before it was a cushion to kneel on. Two medical bags on either side of the box held electric blue viscous liquid. Tubing ran from the bags to a couple of suction cups positioned upright on the floor inside the box frame.
"Here you go, kitten. Let's get you set up," my mistress directed me to kneel on the cushion in front of the box.
"First, in goes the gag, which will also help us monitor your levels of pain and arousal. Red is pain, blue is arousal, purple is a good mix of both." She held out a short thick phallus, and pointed to the base where a large light glowed white. She put it in my mouth-- it stretched my mouth almost to the point of discomfort and curved slightly downward as it slid over my tongue and to the back of my throat-- not enough to cut off my air completely, but uncomfortably close. She adjusted the straps to keep it in my mouth. "There we go! Glowing a nice lovely blue already, I see. And glowing brighter by the moment, too -- you like having your mouth fucked by a big cock, do you? Gagging a bit as well? Oh yes, that definitely got quite a bit brighter."
My eyes started tearing in humiliation, but I arousal swept over me as well.
"Next, let's keep your arms out of the way, shall we?" With a deft bit of ropework she tied my arms to stay where they were crossed behind my back. She did something to tighten the rope and my breasts jutted forward even further than they already were.
