Help Dr. Emery Verlax Further, Voluntarily

"You've been nothing but a gentleman to me this whole time, and, I trust you. If there's anything I can do, then I'm willing to help you. You said a stronger serum would have an adverse effect on my mind, right? Like, make me stupid or something?"

The doctor was shocked. "Katie...?"

"So, if you want, you can use that stronger serum on me. You're a scientist, and I'm just your subject, aren't I? I'm willing to sacrifice a little bit of intelligence if it means you can continue your research. You don't seem like a horrible guy, and I don't know anything about what you do, but it seems real important, and...well, I guess, if I'm gonna be here, I might as well help you. I've got nothing else, I guess. Might as well be a lab rat."

The doctor couldn't believe what he was hearing. For he had never had someone willing to give up themselves to science, no, not in the way Katie was. He could not believe she would sacrifice her intellect, her ability to think, just to further his research. It was the greatest act of selflessness he had ever witnessed.
"Katie, are you sure? I have not told you what a stronger serum will do to your mind. It could reduce you to a simple-minded, bimbo. Is that something you are willing to risk, all for my research?"

"Absolutely. You're not a bad guy. And, even if you are, I guess I'm just dumb anyways then to trust you." She smiled.

The doctor was in tears. No one had ever been so kind to him, so selfless.
"Thank you." Was all he could muster to say.

Katie got out of the chair, walked up to the doctor, and embraced him, hugging him tightly. "It's alright, Em."

"Thank you. Thank you, Katie. You don't know how much this means to me. I promise you if this research bears the fruit I will truly consider you my favorite subject. Thank you. Thank you." He cried on her shoulder.

She could feel his tears soaking through the white dress, and her tits started leaking milk, again. "Oops. Sorry. My boobs are just so big now, and they're kinda full.

"Ah, no, don't worry. It's quite alright." The doctor responds. He is still in his own head and he's close enough...

Katie looks up and doesn't really think about it too much, and kisses him. It's a nice kiss. And the doctor seems to come out of his head for a second.

"I-uh-er, That..." The doctor struggled to find his words.

"I wanted to kiss you myself before I lose my mind, that way it isn't just some result of an experiment. It's a choice."

The doctor's glasses fog up and the lights glare off them, as Katie wipes the tears from his eyes and the snot from his nose.

"You're a very beautiful woman, Katie." The doctor says, finally.

"Thanks." Katie says, she doesn't really know what to say.

"I'm going to give you the stronger serum now."

"If you're the one doing it, then it's okay."

"You have no idea how much this means to me. How important it is."

"Yeah. But I'm still gonna lose my mind, right?"

"Yes. You will become a dumb, bimbo, a mindless, sex crazed cow, by my calculations..."

"And you won't hurt me or take advantage of me, right?"

"Never."

"Then let's do it. I'm ready."

"You're a brave girl, Katie."

"Thank you."

The doctor takes the vial, and injects it into Katie's arm. She feels her body start to heat up, her pussy starts to moisten...
