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 large machine. A transformation machine. It's not the same one you were originally transformed in, but a much larger model. Currently, it's about the size of two king size beds, side by side, but it looks like it can get larger by attaching more to the sides and bottom. You take a look around the room, and notice it's quite similar in decor to other transformation rooms. Machines, tanks, computer monitors, the like. It's about the size of a basketball court. A main desk seems to be in the center of the room, right before the machine. No doubt that it's Alex's desk.

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."

Alex kicks her legs back down, and starts typing away at her keyboard. Five minutes later, the machine whirs, and a sheet of black latex covers everything on your body including your head.

"So, May... How do you feel about spiders? Bet you've never seen a sexy spider before. Well, don't worry, because you're about to see two of them. I turned that silent, green haired nobody into a lusty web machine. I gotta say, it suits her incredibly well. But, who knows? Maybe you'll surpass her in terms of sexiness..."

Alex presses the enter key, the machine whirs to life, and the latex straps bind to you like constricting snakes. First, you feel your legs lift against their will. Then you feel a strange pressure in your butt. It starts expanding, but not just a little bit. It starts inflating rapidly, like a balloon.

"MMMMMMMMmmmmMMMMMM!" You scream from behind your gag.

"What the hell?" You think to yourself. "What... What's going on? What's happening to me?"

Alex chuckles to herself.

"Yeah, this transformation in particular's gonna feel a bit weird... Spider anatomy isn't much like human anatomy at all."

Your butt just doesn't stop growing. It's the size of your torso now, and doesn't show any signs of stopping. It doesn't just lengthen either. It gets fatter, and in addition, your buttocks start to fuse together. It jiggles when you wriggle around in the agony of this overwhelmingly strange sensation, despite being strapped down so tightly.

Your legs keep bending, and you can feel the bones in your hip start to snap and reform. Your feet start to shrink down into points, and right under your them, between your growing butt and your thighs, you start to feel two large nubs, the size of baseballs start to form. You also start to feel a headache as the transformation continues, and your eyes are starting to hurt.

"Stop... Please stop..." You think to yourself. But it doesn't stop. It only starts ramping up more and more.

Your ass continues to grow uncontrollably. It's now the size of a beanbag chair, and perfectly round. Your asscrack has closed completely, apart from a single hole at the very end. You slowly start to feel your anus extending down into your butt, overtaking what used to be the inner side of your butt cheeks.

You feel a strange tingling sensation in your vagina. As if you were growing an extra organ. You feel the bones from your legs disappear completely, and they start to round out into pedipalps, a spider's frontmost, smallest leg-like limbs. The nubs behind them start to grow into pairs of legs themselves, and behind those, another pair of nubs starts to grow.

Your forehead starts to really hurt now. You want to clutch it in pain, but you cant. So, you can only scream and writhe in agony for a moment. The pain becomes unbearable, and your mind goes fuzzy. After a minute of pure pain however, you notice something's different with your head.

You now have six extra pairs of eyes in your skull. They're considerably smaller, and you can't seem to see anything but darkness, but you seem to be able to open and shut each of them individually. You let out another muffled scream of horror.

"Why? Why is this happening to me!? I want it to stop! Please, let it stoooooop!"

If you were to be seen in the state you are now, people would call you a freak. Sure, they'd call any arachne a freak, but you in particular were a half-baked, fleshy, arachne/human hybrid. You had a bouncy, skinned spider butt, three pairs of boneless, footless legs with humanoid calves, eight eyes, all solid red, fingers that ended in claws, and sharp, long, vampire-esque fangs.

The final pair of nubs grows into legs, and your anus reaches the end of your butt. It feels weird not having anything surrounding it. You can feel it grind on the smooth, rubbery latex. Suddenly, you feel another organ start to form underneath your anus. Four, tiny gross nubs start to form into silk-producing organs.

You've just grown spinnerets.

Tears run down from your eight eyes, and you softly sob to yourself. This was all way to weird. It wasn't natural for any living creature to undergo such a dramatic metamorphosis. You felt like the protagonist of a Franz Kafka story.

Your jiggling butt is no longer just a butt. It is a spider's abdomen. It's filled with not only your anus, but also your large intestine, expanded ovary, and large intestine. Your vagina has grown, and is the merging point between your human and spider half. It's obtained and ovipositer, which will aid you in reproduction. Your womb has completely disappeared, as you now lay your eggs outside of your body.

"What... What have I become?!" You wonder to yourself.

Your skin starts to harden. Your four pairs of legs, your pedipalps, your forearms and hand, and finally your massive ass, all start to harden. Your skin becomes an exoskeleton, and turns black. The tips of your legs turn a dark brown color, and sharpen into points. Your hands and forearms become gauntlets of shelled goodness.

Finally, the machine stops. Alex smirks, and you're released from your binds. You fall from the machine, and land in a heap. You struggle to stand, but the number of legs at your disposal only makes you trip over yourself again and again. Finally, you give up, and sprawl out on the floor. Your pussy touches the cold floor, and a chill runs up your spine.

"Aw..." Teases Alex. "Is widdle miss Muffet all twuckered out? Don't worry, dear... You'll figure it out eventually... But for now.. I think it's time we move you downstairs..."

A group of eight yellow-haired women move your body out of the room, and onto a transport cart. Your hands are bound behind your back. C.C. is on a similar cart in front of you. She's already been turned into an arachne, and has a ball gag in just like you. However, she's not black, but a shade of dark green with bright yellow stripes. She turns her head to you and gives you a sorry expression.

Alex struts out of the room and starts rubbing your butt.

"Okay, May. Here's what's gonna go down... You're gonna get transported down into this place called the Unlit Dungeon. A bunch of unused rooms where I like to trick would-be-escapees into going. You and C.C. are going to be good little spiders, and impregnate whatever girls you catch, GOT IT?"

Alex sticks her middle finger up your ass. You give a short yelp and accidentally release a few feet of silk from your butt. You bend over and start to cry. Alex laughs.

"Aw... Looks like someone had a happy accident, didn't they? Felt good, huh? Well, it's gonna feel even better fucking up those prison-break bitches. In fact, with the libido increase I gave you two, you won't be able to resist them! Have fun!"

Alex slaps your ass, and you and C.C. are pushed along by four yellow-haired staff each. You would never again be normal humans.
