My Stepsister is My Ex-Girlfriend - Volume 7 - Chapter 3.06

The Girl Friend Who Doesn’t Stop Growing

Mizuto Irido

“A’ight gang, I’ll be back,” Kawanami said before slowly jogging away to get to his event, leaving me and Isana by ourselves in the corner of the tennis court.

I continued reading while Isana played a game on her phone. Occasionally, she’d start talking as if she’d remembered something she’d forgotten to say.

“Hey, Mizuto-kun?”

“Yeah?”

“Games have recently been trying to decrease the skin exposure of their female characters in order to lower the age ratings.”

“Uh-huh.”

“To do that, they have them wear stockings. Thoughts?”

“Uh... What kind of reaction are you looking to get from me?”

“Well, wouldn’t you agree that it actually makes them even more lascivious?”

“Oh, so you want me to agree with you? Well, I can’t, because I don’t.”

“What?! You truly believe that bare legs are more perverse?! Does that mean that when you remove my socks, you’re secretly getting turned on?!”

“You’re muddying things. Look, there’s a certain person around me who loves to wear stockings and tights. That’s why even with a gun to my head, I wouldn’t admit having any kind of sexual attraction to that.”

“Hm? Oh... Now that I think about it, Yume-san has almost exclusively worn tights since I met her.”

“Apparently she’s not a fan of showing her bare legs. That being said, she totally does in the summer.”

“So that must mean that she’s returned to wearing them! Meaning, since the last time I saw her, she’s been... Heh heh heh.”

“Tone down your inner lecherous old man. You’re being gross.”

“I don’t particularly see a problem with viewing Yume-san’s legs in a sexual manner. Is that not what it means to like someone romantically?”

“No.”

“Have you truly not viewed Yume-san sexually?”

“I...want to keep my feelings for her separate from lust.”

“The male heart is quite complicated. My feelings, on the other hand, are all jumbled up.”

“I can’t act on every last one of my instincts like you do.”

“In that case, perhaps if I begin wearing stockings, you’ll begin to truly view me in a sexual manner.”

“Our friendship’ll be over if that ever happens.”

“Hm... I believe it would be healthier if we’re open about these things, though.”

“Actually, what’s even the difference between tights and stockings?”

“The denier is different.”

“What’s that?”

“Simply put, the thickness of the material. Tights are thicker than stockings.”

“I see... So the darker colored ones are tights.”

“Which do you prefer? I’m partial to stockings, myself!”

“Hm... I guess tights.”

“Really? Is that right?”

“Stop grinning like an idiot. There’s no hidden meaning, so stop making assumptions.”

“I haven’t said anything, though.”

This was how we spent our time during the sports festival—having these kinds of conversations with the commotion and announcements from the sports festival as background noise. After a bit, it sounded like one of the events ended, because we heard an announcement, calling the next participants.

“All participants in the girls’ tug-of-war...”

Hearing this, I lightly nudged Isana’s side with my elbow. “Hey, tug-of-war. You’re up.”

“Huh? Oh! That’s right!” I knew it. She forgot. That was close. She exhaled. “How bothersome... Well, I suppose I’ll get it over with quickly enough.” She tried to puff out her chest, stretching her back, but then there was a snap. Something had broken.

“Are...you okay?” I asked, noticing that she froze. “What was that noise?”

“Oh, uh... Well...” Isana looked worried as she slowly put her hands around the middle area of her chest. Her face began to gradually turn pale. “Something, uh...broke.”

“Huh? What did?”

“My bra’s hook.”

Huh? Hook? Like, the thing that keeps everything together? “Did it break...just now?”

“Indeed... It occurred when I puffed out my chest.”

Is she holding both of the cups in order to keep the bra from falling off? “I don’t really know too much about all this, but are you just wearing your usual bra? Aren’t there ones designed for sports?”

“I-I put on my usual one out of habit. Ultimately, I deemed it too much work to search for my sports bra, so I decided this would suffice! I believed I’d be okay because the only event I signed up for was tug-of-war!”

How is she so unprepared? Also, she really had horrible timing. Of all the times it could’ve broken, it broke now?

Isana hunched over and shut her eyes. “I cannot believe this! Everything has been going so well recently, so I completely let my guard down.”

“Do bras usually break?”

“It’s happened to me occasionally ever since middle school. I frequently had to equip myself with larger sizes.” Ah... I see. Wait... Does that mean that she changed sizes...again? “I was fine at the beginning of the year! I blame you, Mizuto-kun!”

“Huh? Why?”

“You stimulated my female hormones! You rubbed them not too long ago!”

“Strictly speaking, I didn’t rub them... But...did your size really change?”

Isana fell silent and looked down at her cleavage. “I’ve been thinking that it’s a little tighter than usual.”

“Ah. I see... Well, you’re still just a first-year. This is...normal.”

“It’s your fault,” she said, shooting me an accusing look. “You...lewded me.”

She phrased that so weirdly that it caught me off guard. Lewded? Is that a joke on double Ds? “You pronounced that wrong on purpose, didn’t you?”

“Yes, for the double meaning,” she said, giggling embarrassedly while groping herself as if to check the size of her chest. “Well, if I were to buy one with adjustable straps, I believe I might fit into a G-cup... Do you think it’d be safer to ask my mother to buy me a new one?”

“Don’t ask me.”

“What kind do you think I should get?”

“Like I said, don’t ask me.”

She’s playing with me. I was a hundred percent confident about that, if not more. I looked away from her. “In any case, you should figure something out, or you’ll be late.”

“Mm... I suppose I have no choice. I have no time to fix it, so for now, I’ll just have to...” She began rummaging underneath her shirt and in the next moment, she pulled out a light pink bra from the collar of her jacket.

“What are you doing?!”

“Could you hold on to this for me?” she asked, dropping it in my lap.

I stared at it in disbelief. It still had the warmth from her body on it. “N-No, wait. I can’t—”

“I’ll be honest—this is plenty embarrassing for me as well,” she said, slightly flushed, while staring right at me. “However, I prefer this to the alternative situation in which it falls off in the middle of the tug-of-war! I’ll be right back! Please keep it hidden underneath your jacket! Thank you!”

The jacket helped cover her body’s lines, so nobody would think that she wasn’t wearing a bra. Since there was no running or jumping involved in the tug-of-war, she was most likely right that nobody would find out. But then there was I, who knew the truth...

“I’ll be back...” Isana said, determined.

I had no words. All I could do was watch as she walked away, leaving me with guilt and the torment of having this bra, with cups as big as my palms, still warm from the heat of her body. As bad as I felt about it, I had no other choice but to hide it under my clothes.
