Lily was still at home flipping through her textbook when her programming began to kick in. Normally, she'd be out with friends on a friday night, but second year OChem has been hitting her hard. She was weeks behind with a midterm next monday. Lily was trying her best, but none of the course material seemed to stick in her head. What was Markovnikov's rule again? What is an Evans Aldol reaction? Why does -CX3 leave in a Haloform reaction? Lily plopped down on the carpet, with her textbook resting on her crossed legs, and started with her first question. So during the addition of a protic acid HX... the electrons from the pi-bond attacks the H... and this forms a carbocation... what? Lily had unconsciously started to play with her nipple while reading. Nothing sexual or anything, just fidgeting with her tits through her t-shirt. Anyways, back on topic - her tits... they were so big, straining... wait, no... carbocations, right! Yes, a tertiary carbocation is more stable than a secondary carbocation which is more stable than a primary carbocation... So the intermediate state would be... her fat tits? No... She had to concentrate... but her tits... they felt so dumb in her hands... big fat dumb lumps of flesh that were fun and sexy to play with... making her dumb when she played with them... mmm... Lily's eyes rolled back in her head. She had to concentrate, but her tits were making her so dumb... so dumb... Yes... "My tits are dumb", Lily mindlessly repeated mantras that her waking mind had long forgotten, "and I am my tits... I'm dumb... Dumb tits... Dumb sexy fat tits..." Lily was drooling on her tits, unaware, as both hands cupped them. "Here comes dumb sexy fat tits bouncing up and down to her master..."

With that, Lily's pre-programmed body pulled down the neckline of her shirt to let those sexy fat mounds of pure dumbness spill out. A big fat slobber of spit landed on her newly bared skin, on pages of her textbook full of knowledge that Ms. Dumb Sexy Fat Tits would never understand. Lily's mind was gone, only her programming remained. She had set her phone on the coffee table so avoid distraction while studying. Without a thought, she had picked it up and started dialing. 702... 4-etc. Master's number.

"Hello?", Master's voice came through the line.

"Hai... Dumb sexy fat tits here... ?"

Master chuckled.

"Are you blank?"

"Yes..."

"Are you mindless?"

"Yesss..."

"Have you given up trying to understand your big girl textbook?"

"Yessssss..."

Lily droned answers to Master's questions as her tits just sat on open display. It didn't matter that her neighbours could see them from their window. Lily no longer had the will to keep dumb tits under wraps. Her 3/4 naked body just sat there blankly propped up against sofa as her vacant voice droned on, thoughtlessly accepting Master's new commands... Yes she will print off cheatsheets from the link Master sends her. Yes she will smuggle them into class... Yes she will distribute them to Master and whoever else Master commands her to... From xis [Master is canonically non-binary] end, Master could tell by the blankness of her voice, by the video feed from the camera that Lily had been programmed not to notice - that Lily's mind... or lack thereof... was completely open to all commands. This should be fun, Master thought.

On the day of the test, Lily trotted into the exam room with an air of hypnotically induced confidence. The cheatsheets - thin slips of paper that contained all the information needed for the test - were tucked into her waist. All she needed to do was walk by her first assigned client and...

Suddenly, Professor Melnyk's hand was on her shoulder.

"Gimme that"

Lily did not resist. He read the slip in his mind as she just stood there.

"You", he sternly scolded. "Out. And see me after class at 3"

Who the fuck did this girl think she was? He was going to have to file a report to the dean, but he wanted Lily to be there while he did it.

Lily arrived in Professor Melnyk's office with her head low in anxious embarassment. Cheating was already a fail-worthy offense and helping others cheat - she might even get kicked out of the school and be sent back home. What could she even say to her parents? Why did she even do it? She tried to remember, but her head got so... fuzzy. Too late, she was at his door and whatever awaited her awaited her.

"So, I'm disappointed in you."

Melnyk was a stern professor. Lily knew how seriously he took chemistry - and that's what made him the best professor in the department. She was in deep shit.

"What do you have to say for yourself?"

"I... Honestly I don't even know why I did what I did."

"That's what they always say. Listen, you're what... 19? 20? You are an adult in the real world. And in the real world, actions have consequences."

Lily's head hung low. Strands of her brown hair hung over her face. Anything to shield her from the verbal onslaught that was coming her way.

"Is there anything you want me to know before I file this to the dean?"

"Yyyes", Lily stammered. "Anything I could do, Prof. I would do it." She looked up at him, gazing into his dark dreamy eyes.

Just then, Professor Melnyk noticed something - that eye movement, subtle and unconscious - he recalled back to the hypnosis and brainwashing awareness course he took... The way she had been been walking this morning... obliviously following pre-planned motions... reaching to pull the cheat slips from her pant waist... the say she carried herself in her and plopped down... still airy like she's walking in a trance... She's hypnotized, likely brainwashed even. The quick thinking he was known for took hold.

"Yes, Lily. There's one thing you can do: Go deep"

"What?"

"Go deep."

Lily's head hell forward. No will was left in her body.

"Who did this to you?"

"Jasper", Lily droned.

"And what did Jasper make you do?"

"Jasper... Master... controls big dumb tits..."

Lily was already drooling again.

"Controlled big dumb tits into passing around the cheatsheet."

Melnyk studied her as without any awareness, she instinctively cupped her tits and started squeezing. Interesting... Maybe he could harness the sexual component of her brainwashing to his advantage.

"So... You're big dumb tits?"

Lily nodded.

"When you're here with me, you are just big tits, no longer dumb in the presence of my big smart cock."

"Big... smart... cock?"

Lily sounded confused.

"Yes, my big smart cock clears your mind of your brainwashing by the power of its presence"

Lily felt her head clear for the first time since that study session on Friday. She opened her eyes. She was in an office stuffed with smart academic books, seated across her smart as hell professor. He was so sweet and handsome, and his big cock was... so smart? Yes, she could see it stirring under his pants, clearing her mind. So... big... just like Professor said... twitching... If he just took it out, who knows how much smarter she will get? Lily scooted closer and put a hand on her professor's crotch. Melnyk hesitated. He knew this was wrong... but... but he had always desired Lily, and that was wrong too. That sexy little hypnotized slut was going to get him into trouble. Her soft hand was already rubbing the fabric over his rock hard cock. The professor could not resist his urges. He unzipped his pants and Lily naturally began stroking his shaft up and down. The cheating situation can wait. "You serve me now", he grunted, "not Jasper". Caressing her pretty face, he took Lily's obediant head and put his dick in her mouth. Lily seemed as happy as ever, with his big fat cock of knowledge fucking her mouth... getting closer and closer to spilling the seed of knowledge all inside her...

Later that the evening, the two found themselves in a cozy motel room. Lily was perched on the bed in nothing but in high heels, displaying to Prof Melnyk her pussy that awaited the cock of knowledge. The soft skin of the underside of her bare legs was on display too, as well as... cupped in her hand, her big -now smart- tits. Melnyk came out of the restroom fully nude. His big smart cock was ready to go.

"Any bit of knowledge you want me to fuck into you?"

"Yes," Lily teasingly smiled, "How Markovnikov's rule works."

Professor Melnyk's tip penetrated Lily's open and accepting cunt as he started

"So... with an addition reaction..."

Lily listened eagerly as he explained, as he fucked her pliant body. The professor could already tell that with the right instruction, Lily could be an A-student.
