Leave her

"I'm sorry, Miku..." You think to yourself. Sacrificing yourself would be stupid. If you picked her up, you would be shot for sure. The important thing now was to get out of here. You could always transform yourself into Alex at a later point in time.

You make a dash for the end of the hallway, but suddenly, you feel a dart in your back.

"Urk!" You exclaim, and you fall straight to the floor. A second and third dart hits your supple buttocks, and your vision fades at a rapid pace.

"We... Were so close..." You think to yourself and you drift off into dreamland.

...

You wake up, and try to move your arms and legs. They're strapped in. You take a look around, and notice that you're in a machine. A transformation machine. The room looks identical to all those you've seen before, but you're still not sure if it's the same one.

You also notice that you've got something in your mouth. From the way it feels, it's a ball gag, meant to keep you quiet while you transform. Apparently, Alex didn't fool around anymore. Speaking of which, it was about twenty minutes before the bitch actually showed up. You struggled to escape, but not for very long. You'd been in this situation before, and you knew you weren't getting out of it.

"Sorry, I'm late, dear..." Alex chimes as she enters the door. She was in her regular labcoat, and was carrying a clipboard with her.

"I had to check in on the progress of a certain thorn in my side... I thought I'd forgotten about that awful moment of history, but then she had to go and resurface again. It's a shame, really... I was quite interested in that little community she'd put together. I guess all good things must come to an end though... Though it looks like that place is finally going to become the chaotic sex pit I always envisioned..."

Alex smirks, kicks her legs up on the desk and checks her clipboard. You can't do anything but glare at her, and wait for your punishment.

"Honestly, you've all been a thorn in my side. Clearly, it took more than just her to figure out an escape plan. I have a suspicion on who it was, but I'm not taking any chances. I've gotta clear out the lab."

She types away at her keyboard, for a minute, and then out of nowhere, the black straps wrap around your entire body again. They cling to you just as tightly as you remember them.

"I'm really not in the best of moods after that close call May, I got to be honest. I WAS just gonna make you into a harpy, but I think I'd rather take out my frustration on you."

Alex presses the enter key on the keyboard.

"Enjoy your new life as a tentacle monster, May..."

You let out a horrible muffled shriek, and uselessly struggle as the machine whirs to life. You feel your hair fall out of your scalp, and your bones start to soften. Your anus starts to get pulled down to your crotch, and your buttcheeks start to lengthen drastically.

As your entire body starts to widen both forwards and side to side, and your anus starts to merge with your pussy in your taint area, you hear a muffled ring of a phone from outside.

"This is Alex speaking." You hear. Your vagina and anus are one hole now.

"What? Another one? How many is he going to order?"

You feel your spine shorten, and your foot merge into a nub.

"And our reserve experiments? All used up, I suppose?"

You feel your breasts lengthen, and your arms bend backwards. Your hands have been smashed up into dick-shaped ends.

"I get it, I get it... I'll take care of it... Send me a transport, will you?"

30 seconds later, the machine stops. The straps release, and you limply fall from the machine.

You're a half-baked tentacle monster. You're a bit like an octopus, a bit like a starfish, and a bit like a human. Your entire lower half has been replaced by a mound with four tentacles sticking out of it. Each of the tentacles has a penis head on the end, and the underside has a disgusting hole to which your tongue has been moved. You can taste your own ass, your own pussy, and the laboratory floor. Your upper body was a bit more humanlike. You had a torso and a head, but you had four dick-tentacles in a cross pattern where your arms and breasts would be. You had your eyes still, but you had two holes for a nose and no mouth. You had a mess of tentacles as a hair replacement, each of them wriggling with a life of their own.

Unable to say a word, you look down in your body in horror, and clutch your head with your phallic tendrils. You start to sob, and make gross, unintelligible noises from your underside.

"Ugh." Alex sneers. She walks over to you and kicks you in the side. Unable to balance yourself, you're knocked over like a chess piece, exposing your underside. Alex then walks up to your face, and leans in close.

"Listen up, you little freak... Stop your pathetic whining, and pay attention."

You give a voiceless sniffle and stare at the wretched woman with tears in your eyes.

"Today's your lucky day, girl. I have a client I work with. A very famous and rich client. And it just so happens that this client has a kinky fetish for monster girls. Now normally, I don't provide girls on request. It's a rule of mine, you see. But this client pays extremely well, so I make an exception for him. I custom make his girls for him."

Alex stands up straight again and paces around the room, monologuing. You desperately try and push yourself back up. Without any bones in your limbs, it's incredibly difficult. Regardless, you manage to do so, though movement is still not an option.

"I made him an Arachne and a Naga based on specific women. I even made sure to keep their libido to a safe level. I made him a harpy, a slimegirl, and even a centaur. But now, my dear sweet May, he wants a mermaid! As if the crazy fucker didn't have enough pets in his zoo of his! Then again... Who am I to judge."

Alex sighs, and walks back over to you.

"Alright, so here's what's gonna go down. You're the last of the girls from the arboretum. Everyone else has been completed already, and I DON'T retransform completed experiments. I also don't transform maidens, that is, girls who DIDN'T choose to resist me, unless I have no other options. So that means you're not going to stay a cute tentacle monster and fuck girls the rest of your life, and instead, you'll be some lame mermaid swimming around in a fishtank, giving blowjobs to some Japanese businessman..."

You contemplated Alex's words. You didn't like the idea of being some random guy's sex pet, but the idea of being a tentacle monster sounded way, way worse. Your fleshy, pink face lit up with relief.

"I expect I don't need to bind you during transport then?" Alex questioned impatiently.

You nodded.

...

Your first transformation turned you back into a human. However, you noticed something wasn't quite right. Your breasts were bigger, your hair was long and pink, and your body shape wasn't familiar to you. [Meroune Lorelei, Monster Musume]

"What... what is this?" You ask upon being released.

"Does it fucking matter?!" Alex grumbles, annoyed. "I wasn't changing you back into your old body anyways! You've been known as May for what, a week now? Are you that attached to it already, you perv?"

You stare blankly at Alex. She was clearly not having the best day.

"Your name is Mero now. I erased your old name. Deal with it, and get back in the machine before I change my mind and turn you back into a tentacle beast."

You silently nodded. You didn't want to mention to her that she had already blurted out your old name. It was fine anyways, you weren't attached to it at all.

Four guards were surrounding you and Alex, so you didn't dare try and run. You simply got back into the machine and awaited your fate. The latex straps covered your entire body, and Alex started up the machine.

After your tentacle transformation, this one was nothing. You didn't even cry out as your legs were merged into one limb, and started to grow scales. You feel a splitting sensation on your torso as you start to grow gills on your sides. Your skin started to feel a bit funny as it waterproofed, and finally, your transformation ended with a shift in lower body skeletal structure, and the change of your ears into pointy, fin-like ones.

As soon as your transformation was complete, Alex unceremoniously releases you, and your gracefully slip from the machine into a portable tank of water on wheels. You take a moment to look over your new body.

Your lower half was indeed a fish tail. It was light pink, just like your hair. Your tail fin and ears were yellow with a bit of pink on the sides. You had two wing-like fins on the side of your fishy hips that you could operate like vestigial limbs. Finally, your human half merged with your fishy half with a V-shape in the front. It ended with a human pussy, but then transferred into scales immediately after. You had a sort of butt, but there was no crack, and instead there was a nigh unnoticeable flap that covered your anus.

You swam around a bit, and tested out your new gills. You choked at first, and started coughing as you accidentally swallow water, but eventually you manage to get the hang of it.

"Get her out of here..." Alex commands, and a lid is placed over the tank. You sigh, and a stream of bubbles comes out of your mouth.

"Well, I'm not exactly sure what to make of that..." You think to yourself as you're wheeled out of the room. "This day could have gone a lot better... But also it could have gone a LOT worse..."
