“Come on Sally, quit stalling, you know you’re going to pick one of them…” I said with a smirk as the drowsy Sally looked at me, and then the cookies on the table, then back at me.

“I… I… I don’t want to though…” she mumbled out as her eyes went once more to the cookies.

I gave a little chuckle and then reached out and started to pull the cookies away from her, “No!” she almost shouted as her eyes came fully alive and her hand reached out for the cookies.

I think she hadn’t even realized she’d picked up one of the blues ones until it was almost to her lips.

Her shoulders slumped as her face drooped and her lower lip quivered, right up until she bit in to the cookie and her skin broke out in goose bumps.

“See, that wasn’t so hard was it?” I asked but she didn’t respond, her entire focus on the cookie now.

I scootched my chair over a bit and then gently parted her knees and slipped my fingers between her legs.

“You must be masturbating at least three times a day at this point.” I continued as my fingers ran over her damp panties.

“Hey, no panties or bra next time, showing off your tits and pussy is fun. Oh, and I want to see a video of you masturbating as well.”

I leaned back in to my chair and let her finish eating the cookie, a look of pure bliss now across her face.

Three weeks ago when she’d come over to work on our university project together, she’d been the smartest girl in our class, smartest person if I was honest. But that was before a half dozen of those blue cookies and drained 10 IQ points at a time from her, while ramping up her sex drive, lowering her inhibitions, and leaving her completely open to suggestion for a few minutes each time.

“I want to include it in the final report to Professor Johnson. That really turns you on, the idea that some dirty old guy is going to watch a video of you masturbating. The only thing that would make it better would be if you were getting paid for it.”

I continued on for a few more minutes, laying out more and more of her new personality as I did so. She was going to make a great money maker when I was done with her.

Of course, that wouldn’t be until she’d had a couple more of the white cookies. They’d already done a number on her hair, and lips, and tits, but there was still room for improvement.

The only problem was that she’d been choosing the blue cookies the last several times, almost like she was enjoying getting dumber and dumber.

A smile crossed my lips, perhaps after this one she’d be dumb enough to not even notice that there were only white cookies next time.

I chuckled and made a mental note to write that idea down in my journal and give it a try next time, it would make for a good data point in my final presentation at worst.
