Return to the doctor.

"All done," you announce as you step towards where the doctor is waiting. "What would you like me to do next, Doctor?"

She continues to type on the strange contraption. "You're so polite," she replies. "Well, I'd like to make sure everything really is working completely. Do you mind me running some tests? It's important things don't go wrong later, where we aren't at the lab."

"Of course. What do I do?"

"Just stand there. Don't worry. I'll explain what I'm doing as I go. First, your voice. Try saying something."

"Okay," you reply, but the voice that comes out isn't your own. It sounds just like Dr. Freling's. "Ah!"

"That could be useful you know. There, it's back to normal."

"That's quite impressive," you say, comfortable to hear your own voice escape your lips once agin.

"Now if I do this, you should start doing jumping jacks."

"Why would you--Hey!" Much to your surprise, you start doing exactly as she said. It's quite embarrassing, losing control of your body like this, especially with her watchful gaze. You can feel your perky breasts bounce up and down, and with your skirt being short, you worry that it'll flutter up too high. Your face starts filling with colour. But just as quickly as it started, it stops. "Th-That's kind of humiliating, you having that kind of control over my body."

"Relaaax~! It's only me, and I won't **** it or anything. All right. Next, I'm going to test the EROMETER."

"Excuse me?"

"I'm going to admit right now, that even though you're a girl, your sexual facilities don't work exactly like a natural human's. It's almost more similar to a man's in a way. See, you have a meter that increases, and when it reaches the top, boom! Release. It's quite static and straight forward. Though you know, plenty of girls wish they could have such control."

"It's making me really flustered to hear you say this about me," you mumble.

"So, if I type this in, your meter should be set to 20%. There!"

Your eyes widen. In only a second, you feel your body flood with arousal. It may only be 20%, but that's a heck of a lot higher than 0%, or 5%, and you let out an embarrassing quiet moan as this happens. Quickly, you bring your hands over the front of your skirt, and your face turns red. "Ah, y-yes it worked!"

"I can see that," the doctor replies with a smirk. "How does it feel?"

"I th-think you know that already. Can you please lower it to 0%?"

"Not yet. First, I'm thinking 60."

"Wait--"

Mmm~! Oh no, no no! You pull your hands in tight between your legs as your face lights up with a bright shade of red. Over halfway to an orgasm, and all you're doing is standing still. There's a frustrating tingle, like an itch, right where you can't scratch--not now, in front of the doctor. Your legs quiver, and you look down to see your nipples poking through your bra against the fabric of your t-shirt.

"Your pussy should be starting to get a little wet," the doctor explains with a nod.

"Yes, I--Wait, I'm not going to r-respond to something like th-that!" you try to shout back, though your voice is shaky.

Dr. Freling fans her face. She then stands up straight and pulls the lab coat from her back to toss onto the floor. Wearing all black now--a tank top and pants, along with matching shoes--she steps closer to you, still tapping on her screen. "If we don't test this properly, it could malfunction somewhere else. Would you rather us be at a restaurant, and then suddenly your readings start shooting up? What if it got stuck at 100%? in public? We're safe here. Let this be the place."

You nod hesitantly. "All right..."

"Good." She smiles wide. "Because I'm going to crank this up to 90%."

"Hold on, that's too high!"

"Oh don't worry. If you lose control and climax, it'll only be me here to see it. Just us girls."

"Th-That's not my issue--"

Nooo! "Aahh~!" you audibly moan. Swiftly, you cover your lips with one hand as your other pushes against your pussy. It takes all your restraint to not start rubbing around in circles, right over your most sensitive spot. At this percentage, it feels like you could cum at any moment. Your legs nearly give out, but you manage to lean against the counter beside you. Quick, heavy, hot breaths come in and out from your mouth. If it wasn't for your panties, your arousal would be trickling down your legs. You have quite literally never been as horny as you are right now, and what worries you the most, is whether or not this locks you at the percentage, or if your own desires are going to steadily increase it to 100% completely on your own.
