...Back out?

Feeling the cold metal beneath your skin changed your mind for some reason.

"You know what... I don't trust this." You thought to yourself. "Everyone's been disappearing down there for some reason. But at the same time, so many people have actually MADE it down there... It's almost as if..."

You scoot your butt back out of the vent, and wait. Sure enough, nobody came for you.

"I knew it. Alex doesn't care if I go down there. She knows I won't make it..."

But... Now what? What will you do now? You can't go back, and you can't go down. Alex is sure to punish you, and you're sure to fail in the dungeon below. Even if you hadn't ran, you would have been shipped off as a sex **** to who-knows-where?

As you sat and pondered, a group of BLU rushed in through the door. You tried to escape back down the vent, but it was too late. They dragged your screaming, flailing naked ass away through the main hall and back to the room where you were first transformed.

Alex was there waiting for you. Not particularly angry, but somewhat unamused. Without saying a word, she picked you up by your neck and slammed you into the table.

"So you hesitated, huh?" She asked in a bored tone. "Well, I don't know what you were expecting, or if you realized something, but none of that matters now. I can't sell a rebel like yourself to a customer... But, as long as you're **** not to meet your end in that dungeon, I suppose I can make some use of you..."

Alex straps you in and sits down at the computer.

"There's no real point in explaining this, since you'll be **** to follow my instructions anyway... But you're gonna become a YELO. Not really any fun, but you know. You have to have the loyal ones to keep things running smoothly. ...And from leaking secret information..."

The straps cover you again as you desperately struggle and try to cry out. It's no use. You can feel your body changing already. Your body didn't seem to change much. You felt your bones grow, and your body fat move around. Your breasts and boobs in particular grew several sizes, but that was nothing compared to the previous change you felt. No, what really started to change was your mind.

It started as a fuzzy sensation. A warm, fuzzy sensation that clouded your mind. You felt your rage at Alex dissipate, your panic in being trapped and transformed vanish, and you couldn't fathom why. Logically, it made sense. But you weren't angry or panicky or anything. In fact, you felt quite content. It was if those emotions had vanished entirely.

The next thing you noticed was your butt expanding. Not in the usual sense, but you noticed how GOOD it felt. You were quite happy it was becoming bigger. A thought crossed your mind: A dick filling your butt. That would be nice, wouldn't it?

A jolt of excitement runs through your body. You swear you let out a giggle.

Thinking of dicks leads you to think of other things. Thighs. Boobs. Butts. Boobs and butts on hot naked girls. Those girls getting fucked. You being one of those girls. Alex being the person fucking you. Stretching you out with her big, fat dick.

You giggle again. And again. A slew of wild fantasies pass through your mind. Most of them involving Alex. God, what a hot piece of ass. You'd do anything for her. With that hot body and ruthless personality, she's the perfect master.

Before you know it, you're lying down on the table, giggling to yourself, completely unaware that the straps have released you. Alex sighs, and scoots over on her chair, black tape in hand. You look at her in gleeful anticipation.

"...Try not to enjoy this TOO much now."

Alex tapes an "X" over both your E-Cup breasts. You writhe and shiver with delight.

"Yeah, yeah, you and every other one of your sisters... I need to update you girls into something a bit less eager, it's more fun that way."

You calm down and stop giggling, but a smile is still spread across your face. You stand up, and put on the clothes that Alex hands you. A black bikini bottom and a few stray black straps. How scandalous! You love it.

"Now get on out of here and go join the others... You should already know what to do."

...

Your job as a YELO was behind the scenes. You took care of the livestock: Girls being milked, harpies laying eggs, the usual. You were also Alex's agents. Her inquisition, sent to go and fix something anytime there was a job related to secret information. You helped with a lot of Alex's experiments, taking notes, running equipment and carting the "results" to either the dungeon or the sewer. You were also there to help transport girls being sold, though it wasn't until next year that you got the opportunity to help with that.

In your off time, you got to spend time at the YELO quarters. The walls were lined with posters of Alex in the nude. There were multiple computers for which to watch Alex fuck her victims, over and over again. There was even a full-size replica of Alex, which was always being fought over. It was everything you ever wanted.

Well, aside from Alex herself. Turns out, that the only time she fucked you was on New Years, as a gift to her employees. She spread your butt and emotionlessly pumped it full of her cum in a matter of about two minutes. Nevertheless, you enjoyed it immensely, praising and thanking her again and again.

As for Winry, well... It turned out that you had been given a sadistic streak in addition to your Alex-serving personality. The computers showed records of all past experiments and sexual acts. You watched as Winry took part in an experiment against her will, being turned into honey in the butt of a bee girl. Touching yourself, you watched with horny glee as the useless slut was dumped into a trough, and devoured by two other bee girls.

A fitting end for one that defied the goddess that was Alex.
