Part 1

In Stacy's opinion, Jake was the perfect boyfriend everywhere but the bedroom. He was thoughtful, loving, sweet, kind, and supportive... And everyone in their friend group joked about him looking like prince charming. He had perfect hair, a masculine face, and body with just enough muscle to send her over the edge.

And yet, she found herself dissatisfied.

It wasn't his fault.

Far from!

His performance in the bedroom had always been admirable. Some of it even made vanilla sex seem almost appealing to Stacy.

But the longer things went on, the more Stacy had to admit that she had way more fun alone with her vibrator, fantasizing about swinging pocket watches, subliminal audio, and a particular vivid one where she volunteered for a stage magician and slowly fell under his spell as his voice submerged her free will little by little.

Fuck, just the thought of that sent shivers down Stacy's spine.

But...

It was too shameful. Stacy had had a pretty conservative upbringing, and she hadn't known what to do with the strange feelings she felt on the fateful day she watched the Jungle Book, and saw Kaa the snake hypnotizing Mowgli with his eyes.

She had sought out everything she could about hypnosis after that. Episodes of Jimmy Newtron where he had used the hypno-ray, old superhero comics, black and white movies - she couldn't get enough. On one or two occasions, she had "borrowed" her father's credit card in order to buy some hypnosis videos she was far too young for, and thankfully neither of her parents ever questions the extra charges on the credit card bill.

She couldn't imagine what she would have done if they had discovered her dark secret back then!

And now she was a college student, with her amazing boyfriend and she couldn't strike up the courage to tell him a thing they should try in the bedroom.

Stacy was a consummate over-thinker. If she was left idle on her own for too long, she had a way of multiplying her fears and anxieties a hundred fold.

One worry would lead to another, and then another, until she had wasted all of her energy in an evening just worrying about some stupid problem that as often as not didn't even exist.

And so it was no surprise that the thought of telling Jake about her fetish was made more and more impossible the longer she thought about how to do it.

Even asking Jake out in the first place hadn't been this harrowing. Stacy had agonized for weeks, and had so many pep talks with her friends encouraging her to make the first move. But there it was: she had had friends to push her along. But with hypnosis, Stacy didn't have anyone else to talk about it with.

So Stacy decided to take the easy way out.

Stacy was going to hypnotize Jake into the perfect dom.

It was hard to imagine Jake hurting a fly. Sure, he was physically quite impressive - when his friend had invited the two of them to a parkour night, Jake had managed some pretty impressive feats for a beginner, while she struggled with almost every wall and pole - but Jake also cared so much about people, and was just a truly decent human being.

In a way, Stacy was almost more scared of the possibility of him not being a convincing dom. She could imagine a world where he half-heartedly tried to be a little mean and controlling, but in the end only managed to make things awkward.

But Stacy wasn't going to let that happen!

She didn't have a ton of experience with subliminals, but she knew you couldn't make a person do something they didn't want to do.

So she was going to have to be clever.

She mixed the tape, and found a way to play the files as ads on his nightly Spotify playlist.

* * *

After Jake had finished his studying, and was looking down at a calc exercise he barely managed to get through, his thoughts turned to Stacy.

She was just so smart and sexy, and he was sure if he had asked her for help she would have been only too happy to help him with math like she always had in the past.

Jake loved his girlfriend Stacy, and he would never do anything to hurt her. He cared to much about her, and wanted to see her succeed in life.

All the same, he could tell that she wasn't being totally open to him recently. He trusted her too much to think that it was anything too bad, but it still felt like there was a small wedge pulling the two of them apart.

As he brushed his teeth, and settled in for the night, he resolved to have a heart-to-heart about it the next day. If she wasn't going to bring it up, he thought it might be the right time to give her the opportunity to open up if she was ready. Maybe they could grow closer, and understand one another better.

He walked over to the bed, yawned and turned on his Spotify playlist to drown out all the other din that made falling asleep difficult.

As he drifted off, Jake started to have a strange dream.

In the dream, he and Stacy were talking in a classroom, but he couldn't make out exactly what she was saying. [Jake, I know you are a kind person, and you'd never do anything mean to Stacy.] Jake felt the dream take on a strange glow, he was happy that he got to spend more time with his most favorite person in the world. [I know you love Stacy.] Jake saw himself making pancakes for Stacy, and drawing little hearts in syrup. [I know if you thought you were hurting her somehow, you'd never forgive yourself.] Jake smiled at the expression on her face, as she saw the pancakes and hugged him tightly, never letting go. [But I've seen some of the things you do in video games.]

Stormclouds started to roll into the scene, and Jake became distantly aware of himself tossing and turning in bed. [In video games, you're most interested in seeing all the content, and you're totally happy to do an evil play through.] Jake looked around, but he couldn't see Stacy anymore. He started to run around, trying to find her. [So, I want you to understand to the core of your being. When you're alone with Stacy, you will feel like you do when you're playing a video game. You will understand that Stacy is just a pre-programmed NPC, and that you are playing through an evil route of one of your favorite games.] Thunder cracked, and Jake turned around a street corner. It was now night, and he noticed all the people around him didn't have any faces. [You will take on the role of a hypnotist. Study hypnotism, learn everything you can, and then use the Stacy NPC. Hypnotize her, let your curiosity run wild. You want to see all of the things you can make Stacy do. You're not really worried about her feelings, because you know that everything she is doing was programmed in by the game developers for you. You should enjoy the game. Do whatever you want with her, to her, because you are a hypnotist and she is your toy.]

Jake tossed and turned that night, clearly trying to resist the strange ideals the subliminals were filling his head with.

But after a few hours, he became still, and it seemed like the storm had passed for him.

He accepted what he was being told.

* * *

The next day, Stacy and Jake sat together in class, and Stacy tried to see if she could see any change coming over her boyfriend. But he seemed to act exactly the same way as before. Of course, she knew better to expect results right away. Plus, the subliminals specifically said that his change in attitude should only occur when he was alone with Stacy.

It was so exciting for Stacy to watch Jake in the following days, wondering if today would be the day he would finally hypnotize her, and use her as she wished. She imagined him hypnotizing her and tying her up with imaginary rope, or being forced to strip her clothes off piece by piece, or him giving her orgasms with nothing but his voice. Her fantasies alone with the vibrator were particular vivid in those days.

And then, it happened.

Stacy and Jake had just finished up with a board game night at their friend's house, and were in high spirits as they said their goodbyes and started off towards their car. As soon as the door closed, a change seemed to come over Jake. He was still clearly happy, but the innocent joy he had had seemed to have been replaced by a new look that Stacy had never seen on his face before. He was looking her up and down, openly oggling her, clearly thinking about what might be under her clothes. Stacy squirmed, thinking about what he must be planning.

"Is everything okay, Jake?" Stacy said.

"Of course," Jake said, trying to sound casual and missing the mark by just a few degrees. "Say, Stacy. When we get to the car, I have something I want to show you. Does that sound good?"

Stacy smiled trying her best to play the role of the innocent victim, and not wanting to betray how much she could hardly wait for Jake to start taking control.

"Um, yeah I guess so," she said. She leaned her head on his shoulder. "You know, you're the best boyfriend ever, Jake."

Jake smirked for just a moment, as he unlocked the car door.

"After you," he said.

Stacy stepped inside, and Jake got into the driver seat. He started the engine, but instead of driving he pulled out a pocket watch.

Stacy squirmed a little in her seat at the sight of the watch. She could hardly believe her fantasies were becoming real. She imagined Jake fucking her just like he always had, but this time forcing her at every step - making her do things she had been to embarrassed to do before, making her wear clothes she never would have worn.

Jake started swinging the watch.

Stacy let out a nervous giggle. "A pocket watch? You're not seriously trying to hypnotize me are you?"

Jake smiled. "Trying?" he said. "Look at the way you're moving your eyes. You can't keep your eyes off of this shiny pocket watch. Back and forth, back and forth, I can see you captivated by its movement."

Jake was right.

Stacy couldn't keep her eyes off of the pocket watch moving back and forth. Years of hypnosis tapes had rendered her so vulnerable to most of the classic inductions. She felt herself starting to fall, even before Jake said his next words.

"That's right, listen to my voice. There is nothing but my voice for you right now. It is becoming harder and harder for you to resist the heavy feeling on your eyes. You are becoming so sleepy, so very very sleepy."

Stacy tried to fight it. It wouldn't have been fun if she gave in too easy, but she barely had any will to fight. She resisted for a second or two, but soon she found her blinking slowing down, and her breath coming in deeper.

"Yes, you're about to fall asleep. It's so sad how little you can resist this. Your life was yours before, but soon it will be mine."

Stacy rubbed her thighs together unconsciously. She was so ready to just...

"Sleep when I get to three," Jake said. "One."

Stacy's head drooped, and it was so hard to open her eyes.

"Two."

Falling, falling, deeper under his spell.

"Three."

At his words Stacy slumped over in her seat.

Jake blinked for a few seconds, a little surprised all of that had worked. He had been researching and trying to rehearse the lines, but he never imagined the immense effect they would have on his girlfriend. This game was awesome!

Jake started the car, eager to have his fun with the NPC beside him. God, the devs had done such a good job with her. Her movements were so realistic, and he loved the little details the team had included. It almost seemed like she actually wanted to be hypnotized - like it was an almost sexual thing for her.

Jake adjusted his belt, as his pants got tighter at that thought.

He drove towards his apartment.

As he drove, he spoke to Stacy.

"Stacy, things are going to change from here on out, you understand?" he said.

Stacy mumbled agreement.

"You're used to being in control of your life, you're smart, you're ambitious, and you have a will of your own. But now I am in control," Jake said. "Your life is not your own. You are my toy, and I am going to use you. You will do whatever I tell you to. Say 'yes, master' if you understand."

"Yes, master," she said. It was so relaxing giving in, so easy.

"Now, I want you to repeat after me: I am not my own."

From far away, Stacy said, "I am not my own."

"Feel it in the core of your being. You don't belong to yourself anymore. Every time you say it, I want you to understand it more and more. Say it again."

"I am not my own," she repeated. It was freeing in a way. Her life was so hard, and it always required her to make decisions and take responsibility. But if she didn't own herself...

"Again!"

"I am not my own," she said, her voice quaking.

"Now, who do you belong to?" Jake said.

"You, master," she said.

"That's right," he said. "You belong to me. And you're in luck, we're home."

The car pulled to a stop, and Stacy was still slumped over in the seat. Still deep in his trance.

"Stacy, I'm going to wake you up soon. When I do, I want you to understand to the core of your being how things are between us. We are not boyfriend and girlfriend. We are master and slave. And the slave will do everything the master says. She will be whoever the master needs her to be, act how the master needs her to act, do you understand?"

Deep in the trance, a part of Stacy was so turned on. She was ready to be his sexy little slave, so ready to do whatever he told her. So ready to stop having the stressful responsibility of making her own decisions, and letting him make all of her decisions for her.

"Yes, master."

"Good," he said. "Now, wake up when I snap my fingers on 1, 2, 3."

Snap.

Stacy opened her eyes, and looked at her master. She wanted to say something, but she knew better than to initiate a discussion with master.

"Stacy, unbuckle yourself," he said.

She felt a shiver down her spine. The commanding way he said it - like she was nothing to him, like she was a silly slave girl beneath his concern. She did as she was told, rubbing her thighs together.

"Good, now step out of the car and follow me into my apartment."

She followed him, wondering what he was going to have her do.

When they got inside he told her to stop.

"Yes, master."

Jake was loving the amount of control he had over this NPC. But he wanted to test the limits of the game engine. Of course, he wanted to take his evil playthrough as far as he could, to see exactly how depraved the devs would let him get. But he had to answer a simple question first. How advanced was she? How much effort had they put into programming this NPC?

"Slave, I want you to do something for me," Jake said.

Stacy smiled up at her master, ready to do anything for him. She was so turned on by the prospect of serving her boyfriend, of seeing what he had become now that he didn't have his usual concern for her well-being.

"Do my homework for me," Jake said.

Stacy's face fell. She had been hoping for something a little more sizzling, and not quite so mundane.

"Yes, master," she said, after a second.

She walked over to the desk, and started working on Jake's homework. She had always been happy to help him, but doing all of his homework for him was a real drag. Still, it did thrill her a little when she tried to stop, and couldn't. Though she really would have preferred if Jake putting her to rather different use.

Jake, for his part, went to the other room and started to feel his head clear a bit. He reflected on the game he had just been playing, wondering if he should return to check on the NPC's progress in the office. He shook his head. Right now, he was a bit hungry, and in a mood for a different kind of game. He settled onto the couch with some chips and started playing a JRPG that he had bought recently.

He liked the writing of the JRPG well enough, and liked how much more cheerful it was than the game he had been playing earlier. This JRPG happened to have branching storylines based on whether you played a good character or an evil character, and Jake decided to play a good character. While he would play through evil routes so he could get his money's worth and see all of the content in a game, it was usually with a sense of detached curiosity...

* * *

Stacy sighed as she started on the third piece of homework for the night. She was almost done, and she had wanted to see what his next command was, but he seemed content to just have her do his homework.

After several hours, she put down the pen and was satisfied with her work.

"Master," Stacy said, coming out of the office. "I have finished your homework. What would you like me to do next? Would you like your slave to dress up for you, or give you a massage?" She said those last two suggestions in a flirty and alluring way.

Jake blinked at her, feeling himself get back into the role of his evil playthrough. He had almost forgotten that he had told her to do his homework. It had just been a silly request anyways, something to see if the devs had thought of it. "Why don't you let master see what you've got there?"

Stacy placed the homework in front of Jake, and waited as he looked over them.

"Wow, you're a surprisingly capable slave. Do you have ChatGPT controlling your responses?"

Stacy smiled at the compliment. "No, master. I simply did as you asked."

Jake smiled. He was pretty sure he had her number. He guessed that the devs had pre-written a bunch of lines, but also left stuff more open-ended by using an LLM of some kind to provide natural-sounding responses to other questions.

"Well, whatever technology they've got running you, it's pretty impressive. You even did the math - pretty impressive stuff." Jake looked Stacy over, wondering what he wanted her to do next. "You know, I wonder how much I can modify your behavior. The devs programmed you to be a really smart character, but I want you to be dumb and clumsy. Like a total bimbo, can you do that for me slave?"

Stacy's mind raced. In her fantasies, she was always dominated by the hypnotist, but she kept her wits about her. It was humiliating, having all of her brains and knowing that she wasn't in control of the situation. The idea of her becoming not just a slave, but a dumb slave made her a bit fearful. Would she ever be smart again? What would it be like, not being able to think with the full force of her intelligence?

"I can, master," she said. "Would you like me to act dumb for you?"

Jake shook his head. "I don't just want you to act dumb. I want you to really, truly be dumb. I want you to be as different from how the game devs made you as possible. Where you're a serious, ambitious young woman, I want you to become a silly, shallow play thing. I want you to forget you were ever different from how you will soon be, and stop thinking complex thoughts. Do it now, slave."

Jake didn't have a ton of expectations when he gave his command. He was just playing around with an NPC, and was enjoying finding the limits of the commands he could give her, before he really started to explore the storyline the devs had laid out for him.

Stacy felt her mind bending to Jake's commands. She tried to resist, tried to hold on to her intelligence, but little by little thinking and concentrating became so hard. She could feel her memories of college fading. Math, science, history all of these things were becoming things of the past for her - slipping away bit by bit.

Soon, she felt her high school memories rewriting themselves. She wasn't a smart girl. She hadn't graduated top of her class. She was just a drop out, who didn't have anything going on inside of her head. She had always been that way.

Stacy's eyes fluttered, and there was a blankness in her gaze. She smiled at Jake. "I'm, like, done, master! Your slave is, like, totally stupid now."

Jake shook his head. "How do I know you're really stupid? Here, try to read this."

He handed Stacy an essay she had written just hours before.

Stacy blinked and looked down uncertainly at the paper. "Um, there's, like, lots of hard word master. Your slave doesn't know if she can do it."

"Read, slave."

"Yes, master!" she said, feeling a familiar shiver at being given a command. She tried to sound the words out, "Um, 'The puh-hil-oh-sop-hi-cal oo-e-vra of Lud-wig Witt-gen-stein, a-"

Jake cut her off. "Wow, they really went all out with you. You seem like a total idiot now. Are you happy?"

"Super duper happy, master," she said cheerfully. "As long as you're telling me what to do!"

"Hm..." Jake said. "If you're using ChatGPT or something similar, I probably can't do anything too sexual, can I? Bummer, you are pretty cute."

Stacy giggled. "You can do whatever you want with me, master!"

Jake shook his head. He was having too much fun with this NPC to want to risk losing access by violating their terms of service. Later on, he'd see how far he could push the envelope, but right now he wanted to keep things kind of simple. His mind went back to what she had said earlier. A massage or dressing up? Maybe that was as far as the devs would allow him to go. Keep things rated T or whatever.

"Slave, go and get a makeover. I want you to buy a skimpy outfit, and get your hair bleached. Maybe get a push up bra, if you can."

"Yes, master!" Stacy said cheerfully. She got on her shoes, and left the house.

Jake blinked after his slave closed the door. He wondered where his girlfriend had gotten off to? He was enjoying the game he was playing, and he wondered what Stacy was getting up to. Now that he thought about it, Stacy bore a startling resemblance to the NPC in that game he was playing. Wild. He was sure if he showed her, she would get a kick out of the uncanny resemblance when she got back from studying, or wherever she happened to be.

Jake wanted to play more of his JRPG, but he knew he had to be responsible and do his homework. He walked over, and was surprised to find everything already done. He recognized Stacy's meticulous handwriting. Weird.

He always appreciated his girlfriends help with homework, but he would never dream of asking her to do all of his homework for him! He would fail or pass his classes on his own merit. He frowned. The next time he saw Stacy, he'd have to chastise her for spoiling him. Though he'd have to thank her too, it couldn't have been easy to do homework for some classes she wasn't even taking.

He started working.
