And so, it was the next day.
The last class of the day was about to end.
I looked over to see how Natsuki was doing next to me, and she kept glancing back at me. She looked really unsettled.
That's true. I called her in after school yesterday and the day before.
She probably thought she'd be called in again today.
Of course, that was true.
I tore the edge of my notebook, wrote a quick request on it, then rolled it up into a small ball.
About three minutes before the bell rang, I threw the rolled up paper on Natsuki's desk so the students and teachers around me wouldn't notice.
Natsuki, who was still glancing back at me, hurriedly took it and asked me what it was with her eyes, so I gestured for her to unfold the paper.
Natsuki unfolded the paper with a suspicious look on her face.
She read the request I'd written, then looked up and looked at me.
She's bright red.
Burning red.
The sight of the blonde, sharp-eyed Yankee girl blushing in embarrassment is very erotic and cute.
"Please, my sex friend Natsuki?" I say, moving my lips as I smile.
"..."
Natsuki nods, bowing as if she has given up.
Then the bell rang, and as soon as the teacher leaves the classroom, Natsuki leaves as well.
Well. I'll head to the back of the school building too.
***
I waited behind the school for about fifteen minutes.
"Hey. You're late."
"Oh, Miyagi! What's so fun about making me do this!"
Natsuki comes over.
She's not walking with her shoulders squared as usual, but today she's walking a little closer to me.
"Aren't you having fun, Natsuki-san?"
"Of course!"
"But I am having fun. It's so much fun to see my sex friend endure her embarrassment and still listen to what I say. Here you go."
I held out my hand to Natsuki-san.
"Wh-what is it?"
"Show me."
"Huh?! You're making me do this much and now you doubt me?"
I wonder if her face is red because she's angry, or because she's embarrassed about her current state.
Either way, the thought of such a scary yankee girl being at the mercy of my erotic commands is very arousing.
"I'm not doubting her or anything. I just want to see what it's like."
"Are you a pervert?"
I affirm her derogatory words.
"Yeah, right? I said you're a bitch, right? Oh, or do you want to say something naughty yourself again?"
"Huh?! I-Okay, I'll show you! So!"
It seems like she was really embarrassed when I asked her to rub her boobs yesterday.
I see.
Verbal abuse is so effective.
"So, say it like this."
"No, I'll give it to you now!"
Natsuki-san has her hands in her skirt pockets and looks flustered, but I shake my head.
"No. I want to see you get embarrassed. Say it like this, okay?"
"Uh, uh."
I take off my black-rimmed glasses and open my goddess-made magic eyes.
"Ah..."
As soon as our eyes meet, Natsuki-san becomes quiet in an instant.
Amazing, these naughty magic eyes.
I got close to Natsuki's ear as she tried to shrink and whispered.
"C-can you say, 'Look at my panties'?"
"U-uh... ah-my..."
Natsuki stabbed me as she put her hands in her skirt pockets.
What she took out was the underwear she had been wearing just a moment ago.
That's right.
During the previous lesson, I had written this on a rolled up piece of paper.
"After school, at the same place as yesterday. Take off your panties."
That's it.
Natsuki's reaction when she saw this in the classroom was really good.
I thought she would refuse, so I was surprised when she obediently took them off.
"Panties... look... please."
What she handed me on both hands was a plain pair of white underwear.
"Oh, it's white. Cotton?"
"No... that's right, what's wrong?"
"I thought it would be black or red, or silk."
"Such frivolous underwear..."
I see.
In this world, sexy lingerie is seen as frivolous and flirtatious.
Natsuki-san calls herself a tough girl, so she went for plain white.
The design is also safe, or to put it bluntly, it's something you'd find in the underwear section of a supermarket.
For men, it's like plain trunks, or maybe white briefs?
It's hard to compare because I don't know the underwear situation in this world.
To me, pure white panties and see-through purple shorts are equally valuable, so I'm not going to make a silly ranking of which is better.
"Starting tomorrow, wear black. I don't care what fabric you like, but I'd prefer less fabric. See, this covers a lot of your butt."
I took the white underwear and hooked it between my right and left index fingers, spreading them out.
"S-Stop it, what if someone sees you? Besides, what's so fun about looking at a girl's panties?"
"I do enjoy it, though. Besides, you can't tell it's panties unless you look closely. You don't think guys are playing with girls' underwear anyway, do you?"
While I was still wandering around, I enjoyed the embarrassed Natsuki.
"Uh, uh..."
"Besides, this place is completely deserted, so I think it's okay. No one passed by yesterday or the day before."
"Y-Yeah, but is it okay to end it for today? It's so cold and I can't calm down."
"End?"
"Ah, yeah. You were satisfied seeing me in this embarrassing state, weren't you?"
He was a little rough at the end.
He seemed a little angry.
But? It was up to Natsuki-san to decide whether he would get even more angry or calm down.
I slowly removed my glasses.
In that moment, Natsuki-san stiffened as if frightened.
She must have realized that this wasn't the end, but the beginning.
"It's not the end or anything, we just got here, right?"
"B-But what am I supposed to do in this outfit?"
"Lift up your skirt."
"Huh? ...Huh!?"
I crouched down in front of Natsuki-san.
My face was now at about waist height.
I looked up at Natsuki's face from there.
"Hurry up. Oh, it's okay if you go slowly, it'll create a better atmosphere that way."
"N-no, that's not nice..."
"What?"
"What...?"
She looked as if she was really going to do it, but I replied with a look that said, "Of course."
"Natsuki is just a sex friend who does whatever you say, right?"
"Uh, uh..."
Natsuki seemed to have given up, and grabbed the bottom of her skirt, slowly lifting it up.
