This is the start of a mini-arc. I won't be doing the next sixteen chapters this way, but it will pop up here and then.

Chisa loved her students. She loved them very, very much.

So much that she could barely hold back her desires when it came to them.

She always mentally defended herself by saying that it wasn't her fault pretty much all of them were incredibly attractive, but as a teacher, she knew she couldn't simply come out and ask to have sex with them. She wasn't fully sure of the legality, but morally, it felt wrong, even if that was only a mild deterrent.

Still, it was enough to keep her from acting on her desires for the most part.

But as the teacher would soon learn, some situations could end in her favor, allowing her to act out on some of those desires with only a slight risk of consequence.

As long as she made the experience as amazing for the student as it was for her.

It all started with a one-on-one meeting with Hiyoko Saionji after class. Despite her arrogant attitude and how often she bullied people like Mikan, Chisa had always found her to be insanely adorable, and the day she'd accidentally overheard that the girl didn't wear a bra under her kimono, she nearly came right then and there. She'd managed to hold it in, though, and today, surprisingly, she wasn't even thinking about anything lewd while she was talking to her.

"You know you can't keep doing this."

"I-It's not my fault!" Hiyoko cried as she stared at the paper with the horribly low grade on it. "Some of the material is just…not my thing."

"You know that's not an excuse," she said, and Hiyoko shook her head.

"It's an explanation, not an excuse!"

Chisa sighed as she leaned forward. "You know if you continue, you won't get a good enough grade to continue. Then, you won't get to be in the same class as Mahiru." Hiyoko perked up, looking scared.

"P-Please, professor! Is there anything I can do to raise my grade? Any sort of extra credit?"

Chisa nodded her head as she pulled out another paper. "Lucky for you, there is. If you can properly demonstrate your talent in an acceptable way—according to my discretion as your teacher—then I can count it as an extra credit. I will only do so if you can promise me that you'll start working on properly raising it with real assignments, though."

"I-I promise! Just tell me what to do!" Hiyoko said, and Chisa was about to open her mouth when an idea struck her like a car. She looked back down at the paper.

'According to the instructor's discretion'.

That was quite vague…and just enough that it made Chisa's eyes widen. That meant that she could determine what counted, right? She could be the one to decide what was enough, so…

"Okay, then," Chisa said, trying to keep herself calm. "Do you want to do it right now?"

"Yes," Hiyoko replied earnestly, and Chisa couldn't stop the small smile that briefly appeared on her face before she forced it back into a neutral expression.

"Then you're going to dance for me."

"I can do that!" Hiyoko said as she turned around to take a step back.

"But you're going to do it naked."

Hiyoko stopped dead in her tracks and slowly turned around to face her teacher. "Eh?"

"You need to prove your dedication to your craft in the face of adversity, so you're going to dance completely naked for me," Chisa explained, barely able to stop from touching herself at the idea alone, much less what was about to happen.

"I-I can't do that! That's-"

"Then you won't get any extra credit," Chisa said firmly. She knew there was a small chance that Hiyoko simply wouldn't accept it, but she also knew the girl enough to know that staying with Mahiru meant the world to her, so she was positive she would relent.

And she did, though not without a fight. "A-Are you sure I can't keep my underwear on?"

"Nope. You need to prove your total dedication. Don't worry, it should just be us," she assured her. It was after hours enough that it was unlikely someone would bother them. And even if they did, they could just reschedule if Hiyoko chickened out after that. Hiyoko whined and stomped her foot like a child but didn't say anything else as she turned around.

"Fine! Just…don't watch me while I'm…t-taking things off. And I swear if I see your phone, I'm breaking your knees!"

Chisa nodded. She was sad she hadn't thought of a plan to record this, but she was sure her memory alone would be enough to get off to for weeks if not months.

With that, Hiyoko huffed and started to undo the sash on her kimono. "You'll also need to help me put it back on since I can't do it by myself." Chisa nodded as she pretended she was looking, but was, in reality, staring hard at the small girl as her kimono slid off her body, revealing that she wasn't wearing a bra at all, just like she'd heard. She instantly felt herself getting wet, especially as Hiyoko bent over and pulled down her panties. Watching them slide down over her tiny, petite ass sent a shudder down her spine, and she had to cover her mouth to keep from moaning. She couldn't believe she was getting to see Hiyoko's beautifully cute butt!

It got even better once she removed her socks and shoes, then turned around, and she was now staring at her nude body, though Hiyoko was covered up at the moment. Her face was beet red, and Chisa turned to face her completely, seeing her pouting as well. It was so cute that Chisa could barely contain herself, though she couldn't stop her hand from sliding over her groin, covered up by the desk.

"Y-You can begin," Chisa said, trying to steady her voice.

"I…I don't have enough room," Hiyoko said quietly.

"You can move the desks," she said, and Hiyoko seemed to shrink down as she turned and walked to the desk. Chisa simply enjoyed the view as she watched the girl's hips move as she pushed aside the various desks to make room for her performance. Chisa took the opportunity to reach down and slide her panties down her legs, depositing them in a desk drawer while Hiyoko had her back turned. She also discreetly set up her phone and hit record, a hand already snaking back between her legs, where she found she was already wet. She made a mental reminder to clean the chair off later.

With enough space finally secured, Hiyoko turned back to face Chisa, no longer covering herself, as she'd likely realized it wouldn't matter. Chisa nearly felt the wind get knocked out of her as she gave the girl several look-overs. Her chest was small but noticeable, the meager mounds topped by cute pink nipples. Her stomach was slim, leading down to a bare groin, though Chisa couldn't tell if it was because she shaved or didn't grow hair at all. Either way, it was an absolutely wonderful sight to see, and Chisa was happily going at it behind the safety of the desk as Hiyoko took a deep breath.

She didn't seem to need Chisa to tell her to start, as she began on her own. Her face was still red as she began to move back and forth, and she even closed her eyes, though Chisa couldn't tell if it was to concentrate or so she wouldn't have to see Chisa watching her. Either way, she quickly seemed to get into it as her bare feet slid across the floor, and she acted as if she had fans in her hands.

For Chisa's part, she was fingerblasting herself to high heaven with a hand discreetly over her mouth to keep from moaning as she watched Hiyoko's tiny tits jiggling around. Her eyes wandered all over the girl's small frame as she thrust two fingers in and out of her dripping pussy with more vigor. She could already feel the coming climax was going to be a strong one, and her eyes were absolutely glued to Hiyoko the entire time.

Eventually, all the clumsiness faded from Hiyoko's body, and her blush faded a bit as she continued dancing, putting on what was an amazing performance, even without any clothes, music, or props. It was clear she knew exactly what she was doing, and it was wonderful to view. Even if Chisa could barely pay attention to the dance itself over how sexy Hiyoko's small nude body was and how good she felt as she finally came, spilling her juices all over the chair and experiencing the strongest climax of her entire life in a matter of moments. She knew now for a fact that she would use this video of Hiyoko as material for a long while.

Eventually, as Chisa was winding down from her climax, Hiyoko finished, panting as she stayed in her final position for a few moments before bowing and then straightening. Her eyes opened and then went wide as she quickly covered herself, having likely gotten so in the moment that she forgot she was nude. "H-How was that?"

"Absolutely…wonderful…" Chisa said as she slowly stood up on shaky legs and stumbled around the desk to her, where she placed her hand on Hiyoko's head. "Although…there is…one more thing I'd like to request…"

"R-Really?" Hiyoko asked, looking exasperated and tired, but Chisa, despite having just cum, was too far gone in her horniness at this point to stop herself. She wanted more, and she wanted to take it all the way. It was how her hands started to find themselves at Hiyoko's waist and chest, her hand groping her small breast as Hiyoko trembled. Chisa trembled at how soft her breast was. "P-Professor…"

"One more thing and I can give you as many extra credit points as I can…"

"Professor…I-I don't think this is…" Hiyoko repeated before letting out a moan as Chisa brushed her fingertips against her pussy.

"Just one more thing, alright~?"

Hiyoko gasped, and Chisa felt it. A tiny drop of arousal. She smiled.

"Y-Yes, Professor…"

It would only be the first of a wave that day, and although Hiyoko was hesitant at first, something must've been struck inside her at the open nudity since she was soon almost begging for more from Chisa as she lay there moaning until she came not once, not twice, but three times before Chisa allowed her to leave. Chisa recorded the whole thing, went home, and proceeded to masturbate a few more times before bed.

And it would only be the first student.

She'd get to all of them eventually.

She swore it.
