You ask for Chiaki to sell harder, and get what you want.

You ask Chiaki if she wants to borrow your glasses. When she tilts her head curiously in response, probably wondering if sharing glasses is ordinarily part of flirting, you spell out your pun for her. She has to be the blind one if she can't see how attractive she is! Her flirting shot didn't need to have anything to do with building up your own faint charms. All it would take was a little salesmanship on her part.

She seems to think hard about that, but looks uncertain. "I don't think there's anything amazing about me. Even gaming is just something I do a lot of... It's barely an ultimate talent. I can't think of anything else about me you'd be interested in."

You laugh in response to that, trying to think of where to start. You feel a bit like a love-struck poet, trying to decide which part of her is the best to start with. The pale skin? The long lashes?

"... Unless it's my chest," Chiaki mutters pensively. "Or my thighs. I think you probably stare at those the most."

Your laughter abruptly stops. Immediately, you begin swearing that there's been some misunderstanding.

"Oh? I thought you seemed really interested in my thighs," Chiaki repeats herself. With leisurely movements, Chiaki pulled herself up onto the desk next to yours, pulling one knee up to her chin and letting you see the full length of her shapely legs. From her short skirt, there's a glimpse of unblemished skin, pinched by the tall, dark stocking she wears. When you look to her face, you see a faint smile there now. You think it was the same one she wore when she'd cleared your game a moment ago. "Now I think we're onto something, probably. What if I make my thighs part of the deal? Would you wanna go out with me... if I promise to let you touch them? What if I promise to squeeze you with them?

... Obviously, all Chiaki would to do to make you agree to go out with her was ask you to do so. You don't tell her that. Instead, you bite your tongue as you let your brain work.

Already, you've realized your conclusion a moment ago was a mistake. It's not the case that the programming effect is limited by the target's flirting ability: it's that the programming effect gradually ramps up the effect starting from the target's baseline. Perhaps even more importantly, you remember how to stop the effect. All you have to do is leave, or respond positively to the target's flirting, which will let them know they'd been successful and can stop. These are some built-in ways you included to make sure you can easily terminate this effect if it's ever activated by accident.

Well, this is an accident, but it's also not something you have any intention of stopping. This time when the two of you are alone is actually the best time to collect data on just how far this can go. So, with the sourest expression you can manage while Chiaki offers to wrap those soft thighs around you, you shake your head and tell her you're still not really feeling it.

Chiaki doesn't look surprised. She's pouting again, obviously racking her brain for a way to successfully flirt with you. "You know... You're probably thinking I don't have any relationship experience. You're right... I don't. But if you're thinking I'm immature, well... I'm not..." To make her point, Chiaki begins shedding her dark green hoodie, allowing you to clearly see the breezy white blouse hugging her chest. Once it's off, she places her arms under her rack and pushes her chest up, almost in your face, to give you a better look. "See? I game a lot, but I'm really an adult. There's plenty of adult things we could do together, probably. It doesn't have to be just match three puzzles, Tomo."

You're sweating bullets by this point, imagining the implications of her words. The idea that you could touch Chiaki Nanami's body felt crazy: the idea that she was saying you could be her first time for some unspecified adult experience felt insane. In spite of that, you continue to deny her advances, determined to push this as far as you can.

... Chiaki still doesn't look surprised, but she isn't pouting any longer. She might be brainwashed and she might be inexperienced, but she isn't blind. She can tell that even if you aren't agreeing, she's having an effect on you. Now, Chiaki finishes her climb onto the desks and moves towards you on all fours, cat-like. When she's in front of you, her large breasts hang in front of your glasses. Her breathing seems accelerated. "Tomo... I'm gonna let you play with me. I think it's probably fine... if you put those fingers of yours wherever you want. There's no time limit, so... why don't you take what you want, right here? Like a demo... Once you get your hands on me, you'll agree to go out with me, I bet. I've never offered myself to anyone else... Only you. When you unwrap a new game... and tear off the packaging... only girls like you and me know the feeling, right, Tomo? The best feeling in the world... I want you to unwrap me like that, Tomo."

This is beyond your expectation. It's not a new side of Chiaki you're seeing, so much as one you've created. And can subliminal programming really make a soft-spoken gamer come up with cheesy pick-up lines like that?! It's your own science, but you find yourself unable to think of how exactly it works.

Badly, you want to take Chiaki up on her offer, to reach out and start popping buttons and pulling her ribbon. You realize Chiaki's been sweating, and that sweat is sticking her white blouse to her incredible chest. She does nothing to stop you from staring straight into the cleavage the new transparency reveals. You can make out faint details of the faint pink bra she wears underneath. You can see a distinct beauty mark over her breast.

Seeing you so intently focused, Chiaki smiles just a bit wider and sways her chest from side to side while playing with one of the licks of her short hair. "I'm better at flirting than I thought... I think. I get the feeling it's really working. If I unbutton my shirt and let you stick your face right in there... Then, can we go out, Tomo?"

As though you're the one who was hypnotized, you take her up on her offer, quickly and clumsily beginning to undo the buttons on her blouse. You don't bother untying her tie, even though it would help what you're trying to do.

Chiaki looks momentarily delighted. You catch that, but you're too busy and blind without the glasses you just took off to notice an expression of confusion start to cross her face. "Tomo...? We're going out?" she mutters slowly.

You don't respond. Instead, you bury your face into the the window of cleavage you've opened up between her tie and the front of her bra. For the first time in your life, you feel the softness of another woman's tits. Chiaki's body is every bit as pliant as you'd expected, although quite a bit sweatier due to the effect of your brainwashing.

"Tomo... T-Tomo!" Chiaki tries to get your attention, patting you on the shoulder like she's tapping out of a wrestling move. "Tomo, please... Um...!" Eventually, she's pushing against your shoulders with both hands, too weakly to get anything done.

Unable to control yourself, you bring your hands up to join your face in enjoying the incredible chest offered to you. You hear Chiaki gasp and pant as you begin playing with her breasts. You know you ought to feel some guilt at messing with her brain, but she was the one who made the offer!

You hear someone clear his throat.

Knowing there should only be two women in this room, you slowly pull your face from the pillowy paradise it's been buried in and turn it to the teacher who'd returned to the auditorium for his things watching the two of you, tapping his foot and crossing his arms. You turn your head from him to the bright red face of the woman you've just been assaulting, then back to him.

You hear Chiaki speak. "It's okay... She's my girlfriend.... Probably?" It's posed as a question.

After that, you and Chiaki were **** to each write a letter on the topic of public displays of affection and submit it to the professor. The two of you were almost as unprepared for that as for the strange fling the two of you began after that incident. Neither of you had any idea how romance was supposed to work, but as a lingering effect, Chiaki seemed to think that as long as you enjoyed her body, that was enough.

You did enjoy her body, but as it turned out, that didn't have to be enough. Regardless of the strange way the relationship had started, a topic which Chiaki never seemed able to reflect upon in a completely lucid way, the two of you had plenty of common ground to enjoy each other's company. It seemed like this was a thing that could actually last. Also, since you'd gotten results, reporting that data would probably be enough for your benefactors. And as long as you kept your other modified devices hidden and remembered which were which from now on, everything would be fine.

... You thought. Probably.
