Oh, what the hell?

You only lived once, might as well go all in! Besides, you didn't need to overdo it, you didn't need to try to butter Izumi up by offering to carry her books for her or something like that. Besides, that probably would've ended badly. You remembered from the game that in-game Shujin had practically collapsed after trying to carry Izumi's stuff for her.

(((That's the spirit, Shujin! Time to worm your way into that busty beauty's good graces!)))

"Wait up! Want to walk to school together?" You called out to Izumi, jogging up behind her. Mercifully, unlike last time you did not trip over nothing, and so your face (and hands) ended up separated from Izumi's humongous chest.

A shame, but one that benefited you far more than it hurt you.

"...I guess. We're already here together, so there's no point in walking separately." Izumi remarked, having paused in place to look at you as you caught up to her. Briefly, there was a suspicious look on her face, before it went away.

...Eh, you couldn't really blame her, after all you HAD introduced yourself to her boobs before you'd introduced yourself to her.

Despite how much the 'game logic' seemed to dictate how you interacted with the lovely ladies of Harem Protagonist, it was comforting to see that you could alter or extend the canon events if you chose to. There was some real potential there.

"So, Mr Mountain Climber, mind telling me why you want to walk to school with little, old me?" Izumi questioned, and while she wasn't exactly glaring at you, she certainly wasn't smiling either.

And her words were anything but friendly. Also 'little old me?' Hah! Izumi was just about the last person you would ever describe like that!

Well, this had been your choice. Time to bullshit your way out of a mess before Izumi thought you were an even bigger pervert.

"What's the matter? Cat got your tongue? Or... was something else on your mind?" Izumi stated, voice an odd mix of suspicion and playful teasing, like she couldn't decide whether to treat you as a 'harmless pervert,' or as 'just another creep from school.'

"No, not at all! It's just not every day a guy like me gets the chance to walk to school with a girl like you!"

No sound of stretching fabric or straining buttons. Rats! Izumi's eyebrows rose slightly at your words.

"Oh, a girl like me? I suppose to you boys walking to school such a busty girl must be a badge of honor!"

"No, that's not what I meant at all! It's just... when would an average, plain guy like me ever get the chance to walk alongside such a beautiful girl?"

*Stretch*

And there it was! Sweet, sweet music to your ears! That was one of the most helpful hints from the game! Izumi hated people focusing on just her breasts, but loved being complimented! Which meant that the easiest way to put her at ease around her was to not focus entirely on her breasts!

Which was... easier said than done.

Izumi's boobs were HUGE. Like, larger than life huge. So huge that Izumi probably could've smuggled volleyballs in her bra! And that sound just now was triggering a Pavlovian reaction! Your eyes were instinctively drawn to the taut fabric of her blouse, which valiantly held in Izumi's massive endowment! Her boobs didn't look too different, the growth had been minor, maybe only a centimeter at most. If you hadn't been looking for it, you wouldn't have spotted the difference. But you DID see the difference- Izumi's bust looked just a tad wider, fuller in her tight button-up shirt.

She was the kind of 'anime girl huge' that didn't exist outside of ecchi or full-on hentai. Seriously, you weren't exaggerating when you said that she was easily the bustiest girl you'd ever seen in real life.

And just like the other heroines you'd met in the last couple of days, Izumi was being altered by the wish you'd made! Good thing her shirt, while tight and distractingly form-fitting was roomy enough that she wasn't displaying any cleavage from the tiny bit of growth she'd just gone through. That shirt was damn-near painted on, clinging to her narrow waist snugly, before pillowing out as the shirt essentially formed two large 'pockets that her boobs were crammed into.

And if her shirt was tight now...

Well, you might be seeing some buttons fly in only a day or two, assuming you were able to raise Izumi's affection as planned!

"U-Uh... beautiful? I mean... of course! Who wouldn't want to be seen next to me! I work damn hard to look this good!" Izumi boasted, stumbling over her words slightly as she recovered from the unexpected compliment.

"Yeah, I bet you have loads of guys lining up to walk you to and from school, to carry your books and supplies..." You trailed off at the frown that appeared on Izumi's face. No sound of fabric stretching either. Damn, you were must've said the wrong thing!

"Ugh... you don't know the half of it! I just wish more people would give me compliments like you just did. I might be one of the most popular girl at school with the male population, but not for any reason I like. Just so you know, Shujin, being told 'nice tits, girl!' or 'damn, those are HUGE!' are not nearly as much of a compliment as some guys might think..." Izumi grumbled, walking side by side with you.

Okay, it was pretty obvious what you'd done wrong. You'd reminded Izumi too much about how the guys at school only focused on her two most noticeable traits.

"Those guys are dumb. You're a lot more than a big, floating chest!" You hoped being blunt like that wouldn't piss Izumi off. Izumi huffed but didn't interrupt, so you kept going. The two of you were exiting the park grounds now, heading out onto the sidewalk. There were maybe another five minutes before you reached the school. Ten if you took it slow.

"What I mean is, there's a lot more to you than just your chest!" Izumi was looking at you now, an unreadable expression on her face. You new you were sailing through turbulent waters now, but you were too far to back out.

"Sure, you might have big breasts, but the first thing I noticed when I was jogging up behind you earlier was your hair!"

"M-my hair?" Izumi was looking at you in wide-eyed surprise, her frown gone.

"Yeah, it's such a pretty shade of blue! And the ribbon in your hair is really cute!" Were you laying it thick?

Maybe. But none of what you were saying was a lie.

"R-really? You mean that?"

"Every word! Seriously, I can't believe those morons are so busy staring at your chest that they can't see how gorgeous your face is!"

*STRETCH*

Okay, that one you had heard, even with the noise of the town surrounding the two of you as you walked down the sidewalk. Izumi's cheeks were bright red, mouth hanging open, and after a moment she whipped her head around, refusing to meet your eyes.

Which gave you the perfect opportunity to see the results of your 'barrage' of compliments.

Skin

Freaking

Tight.

That was how you'd describe her shirt right now. Those rapid-fire compliments had paid off; Izumi's affection had positively shot up, and thanks to your wish, so had her bust!

Okay, saying that her bust had 'shot up' in size was an exaggeration, but...

There was no mistaking things this time. Before, if you hadn't been looking specifically for it, you wouldn't have noticed any difference about her bust. Now, though?

Izumi's breasts were visibly larger. She was probably a good three to four centimeters bigger in the bust than when you'd started walking with her, and you could see the cups of her huge bra starting to press against her taut uniform shirt. A uniform shirt on which the center-most buttons had started to visibly pull apart! Not by a huge amount or anything, but you could see a couple tiny slivers of pale flesh and powder blue fabric where previously there had been nothing but buttons resolutely holding her shirt closed!

"W-well... you got one thing wrong, Mr- Shujin," Izumi remarked, her stern voice broken slightly by the embarrassed stutter. She also switched out her nickname for you with her actual name.

"And that would be?"

"You said that I had big breasts. You were wrong about that! My breasts aren't big, they're gigantic!" Izumi proudly stated, thrusting her mighty chest forwards!

Even though the somewhat strained buttons of her shirt held together despite the sudden surge of pressure she was putting on them, you couldn't help but feel victorious. Izumi hated having perverse attention drawn to her breasts, but as you'd seen in-game, once she was friendly (or at least comfortable) around in-game Shujin, she was a lot more open with the player. Stuff like openly discussing her grievances about her massive chest, teasing or taunting the player with her giant boobs, discussing shopping for bras, and even making boob-related jokes at her own expense!

"Hah, I guess you got me there! I just didn't want to be the one to say it."

"I knew it! You were paying attention to my boobs!"

"I'd have to be blind not to notice them! It's just... I mean, I'm a teenage boy. I like boobs, the bigger the better! But I'd have to be the dumbest person in the world if I didn't pay attention to the person those boobs were attached to!"

*Stretch*

Hah! One more time! One more time! Izumi's huge, fat tits were so massive that you didn't even need to crane your neck to look at them; their sheer size meant that they were pretty much always in your field of vision, even if it was just the corner of your eye! And you saw the tiny gaps in her blouse buttons widening ever so slightly...

"Well... at least your honest. And honest in a way that's refreshing and not creepy. Thanks, Shujin. This was... fun, I'm surprised to admit. Hopefully I'll see you around school!"

That heralded the end of your walk to school with the buxom beauty. You were left smiling as she dashed off down the hall as soon as you two entered the school building.

(((Shujin, my man. You are a natural charmer! I'm impressed, I didn't think you had it in you!)))

'Why are you surprised? Of course I'm going to give it my all when there's so much on the line!'
