The day after the review meeting, Shido and the others were having class like normal.

"Sorry, I feel a little bad. I'll go to the infirmary."

Shido's class was currently having PE. Although he wasn't the type to do this, Shido had his reasons for skipping class today.

After the teacher excused him, Shido did pass by the infirmary just so he'd be able to say he actually went there. After a quick examination, he excused himself and went to where he really wanted to be.

Earlier in class, Origami had sent him a message asking him to skip PE class and meet her. So now Shido was going to the stairs leading to the roof, where they are supposed to meet.

"Origami, you here?"

"Here."

Origami was already waiting for him at the top of the staircase. Shido finished going up the stairs, and soon was standing right in front of her. Once the two of them met up, they opened the door and exited to the roof. It would be harder for them to be found here than in the stairs.

Of course, as she was also part of his class, Origami had also skipped PE, which means she was wearing her PE uniform. Shido once again realized why boys and girls had separate PE classes.

"... So, what is it?"

"Shido surely knows."

Indeed, Shido did know why Origami had asked to meet him. Or at least, he could make a pretty good guess.

Origami had already tried a number of times to have Shido use his ability on her, but Tohka or something else was always there to stop her. And the recent encounter with the Demon Kings made the necessity of the Spirit CR-Units and Shido's ability very clear.

As if to confirm his suspicion, Origami got closer to Shido. So close that he could feel her sweet smell, and his vision was completely taken by her beautiful face.

A second after, Origami drew in closer, and their lips touched. It was a kiss. Shido was a bit shocked at first, but, once his brain processed what was happening, he kissed her back.

They stayed like that for a few seconds, kissing as if nothing else in the world mattered. Shido was impressed at how good it felt. A girl's lips felt soft and sweet. He understood why some couples seemed addicted to kissing.

After a few seconds, the kiss ended and they both took a breath. Shido's cheeks were blushing slightly, and so were Origami's. That was surprising, considering her usual expressionless face.

"Cute…"

Shido ended up saying without thinking, Origami clearly heard it and showed a small smile, which made him blush even more.

"... This isn't enough."

"Huh?"

"I still need more to be able to get a Spirit CR-Unit. So, let's do more, Shido."

Origami said and closed her eyes. What she expected was clear. She had kissed Shido before, now she wants him to kiss her.

Shido gulped. While he shouldn't force the girls into anything, it also wasn't right of him to simply remain passive in this matter. So, this time, he was the one who initiated the kiss.

Once again, he was impressed by how good it felt. He felt like could spend hours or days kissing after he got used to it, and it would never get old. Although she seemed to be trying to contain her voice, it seems Origami was also feeling good.

She wrapped her arms around his neck, and Shido ended up holding her waist. The combination of those actions ended up making their kiss just slightly deeper.

It wasn't anything like a tongue kiss or anything like that, neither of them had enough experience for that. In fact, both of them were kissing for the first time. But still, they were both enjoying the taste of the forbidden fruit that was the others' lips.

"Haa, haa."

"Mm, haa."

After a minute or so, they ran out of breath, so their kiss was brought to an end. Even though their lips separated, their faces remained close to each other, their noses almost touching.

Shido looked into Origami's blue eyes and Origami looked into Shido's golden eyes. Although their cheeks had a tinge of red, neither of them felt like letting the other go. There was the fact that the job was not yet done, but more than that they just didn't feel like it.

"Again?"

"Again."

After that simple exchange, they began another kiss. The third kiss, and things showed no sign of cooling off.

As they enjoyed the feel of each others' lips, they also began to notice the feel on the rest of their bodies.

Needless to say, this was the first time Shido held a girl like this. He was surprised at how Origami's body felt, so much so that he couldn't even describe it if he was asked to. All he could say was that it was soft and nice, be it the lips, breasts, waist, or anything else.

Similarly, Origami was having trouble keeping her cool demeanor going. She had already done many studies and simulations for when she eventually reached this far with Shido, but nothing had prepared her for the real thing. She had never been held like this by a boy before, but it gave her a strange feeling of wanting to let him take charge and do as he wanted.

Without him realizing it, Shido's hands had moved lower. Instead of Origami's waist, they were now on her butt. Shido hadn't realized it, all he knew was that it felt good, and his fingers moved on their own to grope her and get more of that feeling.

"Mm, nnn."

Origami was unable to contain that moan, but it was luckily drowned out by their kiss. Maybe as a way to try and get back, or maybe just to continue feeling good, Origami tried to deepen their kiss.

"Nnnh."

It was Shido's turn to let out a drowned out moan now. Still, he was too preoccupied with enjoying the kiss to really care.

For as long as their breaths allowed it, Shido and Origami enjoyed their kiss. And even after they ran out of breath, Origami pecked Shido's lips a bit. It was a weird feeling, but not unpleasant.

"I love you, Shido."

Origami muttered in between her quick kisses on Shido's lips. Did she mean to say that, or did it just happen to come out? Shido wasn't sure how to react, and then he realized where his hands were.

Embarrassed, he slightly separated from Origami. Still, he couldn't get the feel out of his hands. He almost wanted to open and close them a bit, but he thought that it would be a bit shameless.

"S-sorry, I hadn't realized it."

Although it was technically not wrong and it did help use his ability more than just kissing, it still made Shido feel embarrassed. But Origami didn't seem to mind it.

"It's fine. Rather, you should touch me more."

"E-even if you say that-!"

What made Shido's eyes jump in surprise was Origami pulling up her shirt, revealing her bra underneath it. Although Shido got busy ogling her chest for a second, he was suddenly struck with worry.

The roof wasn't exactly a private space, only a chain fence separated it from the outside, meaning that the visibility wasn't blocked. Sure, it would be hard for someone to look into anything happening on the roof, especially right in the middle where Shido and Origami were, but Shido wasn't exactly rational at the moment.

He tried to grab Origami's shirt to pull it back down, but he froze on the spot. That's because Origami also pulled up her bra, revealing her bare breasts. They were modest in size, but they were still a beautiful girl's breasts.

Shido was no saint, he was a teenage boy with access to the internet, so he'd obviously already seen all kinds of naked breasts. But something like this was a first for Shido, and the suddenness of it made him freeze up.

Origami took advantage of that, grabbed Shido's outstretched hands and placed them on her breasts.

As if that wasn't enough to make the poor boy's face become entirely red, Origami started using Shido's hands to grope her own chest. Shido was entirely stunned by the sensation of touching a girl's bare breasts. Origami also felt better than she expected, as she couldn't stop herself from letting out a moan.

"Mmn, aan."

Even Origami was surprised at the sweet voice that came out of her mouth. Maybe to hide her embarrassment, she convinced herself that it was just another method of making Shido feel more excited.

"O-Origami, y-you, I…"

Shido was still stunned. He couldn't think of any reason to not continue with this. They had to make use of his ability, this was an effective method, and there was no one around to stop them. Yet, something in him still resisted for some reason. He felt that it wasn't right to take things this far just because of his ability. But then again, Origami had said she liked him just now, so maybe it was fine?

However, that meager resistance was easily taken down by a few words from Origami.

"It feels good. Touch me more, Shido."

With that, Shido forgot all about them being at school or his ability or anything else. He decided that, as a man, it was his job to see this through.

Origami stopped moving Shido's hands, but that was no problem as he began to move them himself. He moved them up, down, and to the sides, lightly massaging and groping Origami's breasts.

And of course, he didn't forget about the pink cherries on top, her nipples. Shido could feel them harden between his fingers, which meant that Origami was feeling good. Though her red cheeks and sweet voice already made him guess as much.

Shido and Origami looked into each other's eyes. Then, without any words, they kissed yet again.

Needless to say, their excitement was greater than before. Even without meaning it, they started getting their tongues involved in the kiss, though it was still very timid and unconsciously.

"Mmn, mmmh."

"Nnn, mmm."

At this point, they themselves didn't know what they were doing. They were just letting their lust guide them.

Shido continued playing with Origami's breasts, but now he also teased her nipples. Shido had no idea how much pleasure his pinching was giving her. It made Origami unconsciously rub her legs.

At the same time, Origami's hands aimlessly ran over Shido's body. It's not like she was trying to grab him or anything, again, it was just lust guiding her.

However, her hands ended up making their way to Shido's crotch. Half unconsciously, she started focusing her touches there.

"A, aah!"

Of course, that made Shido feel incredibly good, but he tried to keep his focus on Origami. At some point, he thought that kissing her neck would be a good way to get back at her, so that's what he did.

"Mmm! Shido."

Origami's hand moved up to Shido's head and grabbed it. Yet, she wasn't sure if she should keep him there or move him, so all it ended up doing was giving him a gentle caress.

It would be hard to see anything but a couple in a heated passionate moment. No one would have been able to guess the reason why they had to do these things. Though the two people involved barely remembered it anyway.

A long time passed with them kissing in all kinds of ways and exploring each other's body. They could have probably done it for days, if not forever. But what eventually brought them back to reality was the chime of the school bell.

That sound felt out of place in Shido and Origami's passion-filled world, but that's when they remembered that they had skipped class to be here. As much as they would have loved to continue, neither of them were really the type to skip class, so they decided it was best to call it off here.

"Do you… think it worked?"

Shido asked as they separated. In all honesty, he wanted to ask about Origami's previous confession, but he felt embarrassed by it and found something else to ask about.

Origami put her hand at the center of her chest. She probably didn't intend it, but it ended up drawing Shido's attention to her breasts again. For a second, he wondered if there really was that big of a difference between skipping 1 class or 2 classes.

"It's hard to explain, but I… feel something. Once we get to the headquarters, I'll ask to measure my compatibility again."

Shido didn't quite understand what Origami was talking about, but it was fine. It would be good if this was enough for her to get her Spirit CR-Unit, but if not… well, Shido wasn't against trying again.

While Shido was lost in those thoughts, Origami fixed her clothes. Now they could go back and change into their regular uniforms.

"But, maybe a bit more…"

Origami said before kissing Shido again. It seems that Shido wasn't the only one who enjoyed their time together.

But, thanks to the few minutes they spent on that last kiss, they ended up late to get back to class. Thankfully, they had the excuse that they had both felt a bit sick during PE, though who knows who really believed it.
