"Are you sure you're both okay with this?"

Mahiru asked the question to Chiaki and Kazuichi once more as they stood outside the door of the dojo, where Tenko was waiting for them. Chiaki had asked if Mahiru had wanted to come with her again since it had been a while and Mahiru had asked to bring Kazuichi. Chiaki had only hesitated for a moment before agreeing, but Mahiru still wanted to check with the both of them that it would be okay. That they'd be fine exposing themselves to one another that way, and moving around in a way that would make their…assets bounce and jiggle. Chiaki wasn't bothered since she showed herself off now most of the time anyway, to the point that she currently wasn't covering up, and Kazuichi had assured her he'd be fine, that he trusted Chiaki. Mahiru had called ahead and, though it took some convincing, managed to convince Tenko to train Kazuichi too. Even with all that though, she still wanted to check that it was okay.

"It'll be fine, I promise. As long as Kazuichi behaves himself," Chiaki said half-jokingly, to which he gave her a funny look.

"I'll be good!" he exclaimed, and Mahiru couldn't help but laugh as they walked up to the door and finally went inside, with Chiaki holding the door for them.

Unfortunately, the previous class was still finishing up, which meant several kids who'd been practicing with Tenko and several parents who looked alarmed, angry, or a combination of both at the sight of the naked students, especially Kazuichi. The three nude students moved to some chairs at the back and sat down, Mahiru and Kazuichi initially jumping as they felt the scratchy padding of the seat against their bare behinds. The kids in the class became very distracted, even as Tenko constantly tried to get their attention again.

Once the class was over, one of the kids' parents walked up to Tenko and loudly complained about the nude students, to which Tenko responded that they were naked by government order, and also students of her and the master. The mother argued that that shouldn't be allowed and that her kids shouldn't be exposed to such perverts, to which Tenko told her that wouldn't be allowed, and was out of her control anyway. If the master accepted them, she had to do as he said. The mother then declared that if she were going to allow perverts, including a male that her daughter would be able to see naked, then she wouldn't bring her in anymore. Tenko didn't get a chance to respond as she grabbed her daughter's hand and threw a harsh look at Kazuichi before leaving, while Tenko simply sighed. Everybody else eventually funneled out, though one teenage boy tried to stick around and look through the window before his dad yanked him away.

"I'm sorry about all that," Chiaki said as she walked up to Tenko, but she just waved her hand.

"We deal with people like that all the time." She turned to look at Kazuichi. "So…you're Mahiru's boyfriend then?"

"Y-Yes, hello!" Kazuichi said as he held out a hand while keeping the other over his groin. Tenko narrowed her eyes and glanced at Mahiru for a moment before she eventually grasped the man's hand and shook it. "I promise I'll do my best to follow your command, so I can protect not only myself, but Mahiru too."

"Hm…" Tenko said, but gave a nod of acknowledgment, and turned to Mahiru. "We'll start with the basics then, just like I did with Chiaki." Mahiru and Kazuichi nodded as they removed their shoes and followed the girl to the mat. Kazuichi took a deep breath and after a glance at Chiaki, he dropped his hands from his groin. All three girls immediately sucked in a breath but for different reasons.

Mahiru had already seen it a few times before, but even though Chiaki and Tenko knew what a male's genitals looked like, to see it in person was something completely different. Of course, Chiaki had seen Nagito's briefly, but not only had she averted her gaze that time, but Kazuichi was quite a bit larger. All three stared at it for a few seconds before Kazuichi cleared his throat.

"A-Ah, sorry," Tenko said as she cleared her throat. "Let's get to it, shall we?"

And so they did. Tenko began to lead Mahiru and Kazuichi through the basic movements, which Chiaki used as a way to hone those basics. Tenko had told her that the better you got at the basic moves, the stronger foundation you would have for the more complex ones. So she worked on them alongside the two as they practiced with Tenko.

Eyes ended up wandering a lot. Kazuichi kept watching both Chiaki and Mahiru's chests jiggle and sway with nearly every single movement they made. They did so in kind though as all three girls kept glancing at his cock, which bounced around, especially as it became long and stiff. Tenko looked slightly disgusted at the sight of his clear arousal but didn't say anything, surprisingly. Chiaki guessed it was because she understood that it would be hard for a boy not to get turned on in this situation.

Once they were done with the basics, to where Mahiru and Kazuichi could do it on their own, they moved on to a few more advanced drills, none of them noticing as someone new walked up to the door.

The boy wore a black striped jacket and a black hat that hid half of his eyes in shadows, as well as a pair of black jeans, an entirely dark outfit that reflected the moods he could often find himself in.

His father had told him that if he wanted to be a detective, a potential career the boy had actually stumbled into, he would need to learn self-defense, and this was the best place in the city to learn. He'd checked reviews and found mostly positive words, though there was a note that the master's protégé could be discriminatory towards men at times, though she was more forgiving with younger boys. Despite that, the boy was determined to get this training if that was what was required.

However, when he stepped through the door, mouth opening and ready to announce his arrival, or perhaps even plead to be taught, he froze in his tracks.

Never in a million years would he have expected to see two beautiful naked women and a naked man training.

As young as he was, the boy didn't use the internet very often, and had generally been pretty adverse to pornography and the like, thinking it was pointless. Yet as he found himself staring for the first time at not one, but two naked women, their large and modest busts bouncing and jiggling around as they practiced various moves in the dojo, he suddenly understood the appeal. The busty girl lifted her legs in a kick that briefly exposed the spot between her legs, and the boy felt his dick tightening in his pants so quickly that he instinctively grabbed it. His face burned as she felt like he should leave or look away, but he couldn't pull his eyes from the sight in front of him.

He eventually found himself sitting in a chair as he watched in complete awe at the spectacle, constantly fidgeting and shifting as his dick, I used to such a burst of arousal, twitched uncomfortably. He didn't know if he should speak up at all, or do anything, but finally, the decision was made for him.

"Hey!"

The boy jumped in his seat as he looked over at the teacher, who was glaring at him like he was a dead fish. He immediately leapt from the seat and walked over to the edge of the mat, hoping his erection wasn't too obvious. "What're you doing? Spying on naked girls training, you-"

"N-No! I just didn't know if I should interrupt!" the boy immediately said before he got to his knees, surprising the teacher, who he presumed was Tenko Chabashira, the one mentioned in reviews. "I-I'm sorry, I've just…w-well for one I've never seen a…a…n-naked girl before, and there was that, and I just didn't know if I should speak up and interrupt you, or what was going on, because the door was unlocked so I assumed it was okay to stay and…" He realized he was rambling, and Tenko was staring at him in confusion, so he cleared his throat.

"Let me start again. My name is Shuichi Saihara. I am a detective in training, and I was told to learn some self-defense skills. I came here because it's highly reviewed, but I was so shocked by the sight of naked people training that I kind of froze and collapsed into a chair to watch." He gulped and bent his body down. "I-I know you don't seem to like men, and I'm sorry for staring but please accept me as a student!"

Tenko, meanwhile, was frozen in awe. He'd admitted to staring, apologized for it, and was begging to be a student? And this was the first time he'd ever seen a naked girl? On top of that, when he looked back up at her, and his eyes met hers, she felt…something. A strange tightening in her chest which made her heart begin to beat fast. She lifted a hand to her chest as she gulped, trying to calm herself and confused as to why she felt so…strange while looking at him. "W-Well…that's up to my Master to decide."

"When is he-"

"He's in the back working on something, but I'm sure he can spare some time for you," Tenko said, before turning to Kazuichi, Chiaki, and Mahiru, having momentarily forgotten they were there. "Ah, we went overtime, but I won't charge you any extra, so…"

"R-Right, thank you," Kazuichi replied as he quickly rushed past Shuichi and to where his shoes were, bending down to cover himself up again, even though he knew the boy probably hadn't even been looking at him.

"Thank you for the training. I'll be sure to come again," Mahiru said with a boy as she too covered up again, blushing as she walked past Shuichi, while Chiaki simply gave a happy wave as she walked back as well, and before long, all three were back out the door, shivering and talking about how cold it had gotten as Christmas approached, and then Tenko was standing in front of Shuichi.

"Take off your shoes and you can step onto the mat," she instructed, and he did as she said, following him over the mat and to the back room.

Tenko's Master approved of him joining one of the classes, separate from the nude one of course, and as he laid out the price, time, and uniform, Shuichi accepted it all with gratitude, and seeing his smile had sent butterflies in Tenko's stomach, though she couldn't explain why. Something about it was just so…

Pure.

As he gave Tenko a small bow and left the dojo, Tenko found herself staring after him through the window until he disappeared from sight. She let out a shaky breath as he left, and turned away.

It took several minutes for her body to return to normal after that.
