Hey all. Welcome back to another chapter of A Lesson They Won't forget.

Quick recap: Keima ran away from the class after getting overwhelmed by the situation with Nanaka, and Chihiro and Kanon's entrance definitely made it worse. The four girls and Nikaidou are the only ones who know, so they've discreetly gone to search for him, and Chihiro and Tenri learn that Keima is hiding in the boys' bathroom and they need to get him out.

Other plot threads are following Ayumi, Yui, Mio, Sumire and Akari in the truth or dare group, which is getting more out of control, like the dare that Yui had to go flash the other girls(kinda briefly mentioned before). Jun and Hinoki are helping the other girls take their body on a... test ride, to mixed results... Tsukiyo's a little confused, and Shiori moans a little too loudly when she orgasms - courtesy to Xellos and Zelgadis for that headcanon... the other girls... well, I guess we will see.

I hope you guys enjoy this chapter. It's not the most exciting or eventful of chapters, but you guys can be the judge of that.


Meanwhile, Kanon was on the roof, after having searched the entirety of the second floor… somehow, she doubted she'd find Keima… like why would he even come upstairs if he was trying to avoid the girls… for a moment, she just plopped herself onto a bench, sighing…

She'd been feeling antsy the last few minutes, what with Keima's disappearing and whatever had happened with Nanaka. Considering she'd only known the girl since today, she didn't really think that she had the right to worry, but she still did…

A shiver went through her as a gust of wind blew up her skirt to her still wet pussy, eliciting a hiss and blush from her… how was she still wet!?

Admittedly, this whole lesson was getting her more in touch with her sexuality, but whether that was a good thing or not… she wouldn't really know…

It might be a bad thing… she could barely find 20 minutes alone during the day to masturbate, and she had a feeling that she'd be needing it more than ever…

Before she could think about it further, her phone beeped. Tenri had found Keima and was going to try to convince him to return back. She sighed in relief, before glancing down at her skirt, gently rubbing her crotch, feeling her pubic hair shift under her touch.

God, how she'd love to masturbate right now… somehow, even the thought of doing it on the roof, in a public setting, kind of turned her on… but at the same time, she cringed… she knew she liked the attention, but fuck! Doing that in front of people was just immoral!


Instead of letting herself dwell in those thoughts, she returned back to the classroom. Luckily, the girls playing Truth or Dare bought that she had been playing mobile games on the toilet, and she was free to return to the room to tell Nanaka about Keima…

Except she wasn't there…

She let go of the breath she hadn't realised that she was holding, as she fell onto the bed, face first onto the soft otherworldly sheets…

For a moment, she froze as her thoughts caught up with her… this has been the bed Keima was having sex or God-knows-what with the other girls… and she was going to sniff it…

While her decency begged her to get up and straighten herself, her little devil seemed to get more excited by the thought, prompting her eyes to scour for some wetness which she could smell, or possibly lick…

And she found it too… just a small patch a little darker than the hagoromo the bed was made from… her inner devil cheered before reminding her that she was alone… one little sniff wouldn't hurt…

Despite the very likely possibility of someone walking in, Kanon's brain refused to listen, rather opting to bring her nose closer to the stain, her heart speeding up again as she sniffed… cautiously at first…

Honestly, it didn't smell like much… it was maybe a little more musky, like sweat, but she had to admit… there was something quite lewd about how it smelt… or maybe it was just imagining Keima and some girl intertwined in each other, the product of their lustful feelings spilling out of them onto the blanket,

The growl that came out of Kanon's throat at that image was more animal-like than anything it had produced. Looking up with half-lidded eyes to see no one had come, she hiked up her skirt from the front, her slender fingers heading into dangerous territories…

She wanted to feel good, just like the people who had been here…

Taking a more confident whiff, she located her clit easily, marvelling at how amazing the female body was at reacting to her rollercoaster of arousal… when Nanaka had taken off her panties, she'd honestly been so wet that she could feel it dripping on her legs… but then it had been more or less fine until Chihiro had stuck her tongue down her throat… and now again, thinking of whatever mind-blowing erotic event was happening before…

She closed her eyes and rubbed for a few moments, painting a little scenario for herself… Keima straddled over Nanaka's body, his face determined as he thrust into her confidently, while the Shougi girl wore only a vulnerable look, her face scrunching up at every time his dick entered her… the speed increasing as they came closer, before Keima lifted her up by her cute buttocks, seemingly going even further into her. Her quaking body and the yelp not disguising her climax… followed by his own low groan, as his seed flowed into her, the excess mix of their love dripping stickily from their connected bodies.

That image was almost enough to make Kanon reach her own climax, but a different, more realistic image, made itself known as her eyes opened… Nanaka, watching her gyrate against the bed as her fingers pleasured her weeping pussy… despite her brain telling her to stop… despite the logic that this isn't what any girl would want to see… Kanon continued to rub, Nanaka's innocently surprised face being the thing to get her over the edge.

It was unlike any climax that Kanon had ever had… maybe the flooding waves of pleasure originating at her core were still there, but they were more like tidal waves, each one seemingly heightening the previous one… her fingers slipped over the new wave of juices that she was certain was starting to dribble onto the bed.

That had been so fucking hot…

As the pleasure began to subside, the reality of Kanon's actions started to sink into her head… Nanaka had walked into her paddling the pink canoe with her nose pressed against a spot of the bed she really should not have been sniffing… ignoring the feeling of light-headedness that was starting to emerge, she sat up, pulling her dripping fingers from her folds and wiping it on her skirt, deliberating what to say.

"Hi…" was all her frazzled out head could muster. As stupid as that sounded, it definitely beat her (hopefully) soft moaning from before.

"Uhh… hi..." the orange-head looked to the side awkwardly, "I-I'm sorry tha' I came in…"

"No, I'm sorry I came…" Kanon began, only to hear a snicker from the other girl… then she realised the innuendo behind her words… "no, not that… well, that too…"

Kanon's face slowly became pinker as she tried to fix it, but the humour seemed to calm Nanaka down too, who started laughing…

"Hones'ly, I wouldn'ta pegged ya to be tha' kinda girl," Nanaka shrugged, "though ya gotta do what ya gotta do…"

"I'm not normally like that…" Kanon interrupted, her face still burning, "I was just horny and backed up because I never get any free time…"

That just seemed to amuse Nanaka further, which just embarrassed the idol.

"Hey, you still have my panties!" Kanon remembered indignantly. "give them back and I'll‒"

"On one condition…" Nanaka raised an eyebrow, "ya explain what's goin' through tha' pretty pink head of yers as ya sniffed the bed and went ta town on that…"

Even though that was a euphemism, Kanon felt herself turn pinker than her hair at how brash Nanaka was.

"I-I-I'm sorry…" Kanon hung her head, "I don't know…"

The shougi girl felt her heart sink as Keima's exact words replayed in Kanon's… it was a little ironic that the girl felt guilty for the exact opposite thing Keima felt guilty for, but her mood deflated a bit too much to enjoy that irony.

Kanon didn't miss the teasing look leave Nanaka's face.

"A-are you okay?" the idol asked, her clean hand stretching towards the orange-haired girl.

"I'm alright…" Nanaka's voice broke as her eyes started welling up. 'Alright indeed', Kanon repeated in her head, as she stroked Nanaka's back.

"Do you… maybe want to tell me what was bothering you, so I can try to help you, Nanaka?" she asked, a little surprised at herself that she dropped the suffix so easily.

"Why would Japan's number one teen idol wanna help a cry-baby like me!?" Nanaka fought back stubbornly.

"Because I'm your friend," Kanon answered, her voice equally stubborn, "what I did was inexcusable and I do owe you an explanation that I-I don't even have, but I think it's more important that you tell me what's on your mind so that I can help you first…"

The two girls shared somewhat of a stare-down before Nanaka yielded, her slightly red eyes averting from Kanon's.

"Well, I was doin' stuff ta Keima… like… ya know, tryna pleasure him… but he didn't cum," she sniffled and rubbed her nose with her sleeve, "Ayukawa told me it was coz he'd cum before and guys can't do tha' too often, but even still…"

"You feel like you were doing it wrong?" Kanon concluded, recognising the kind of female logic which she was following, "like you weren't good at it or something like that?"

Nanaka's eyes started welling up again as she nodded. Kanon rubbed her back sympathetically.

"Tenri-san was right though. I saw her ask Nikaidou-sensei when you were inside. You didn't do anything wrong."

"Maybe, but I nearly forced Ayukawa ta strip so I could blow her…" Nanaka felt the shame she'd been trying to suppress as she admitted this, "I was so involved in tryna prove myself and save my pride tha' I nearly hurt my friend… I doubt she'd wanna be aroun' me alone anymore…"

A fresh round of tears began as Nanaka buried her face into her hands. Kanon was wishing that there was anything she could do for her friend to make her feel better… she doubted an impromptu concert would do much here…

Honestly, there was something really endearing about the orange-haired girl which Kanon had noticed from when they started talking… she was honest and straightforward, and seemed to suck at lying… yet, in their first few minutes of actually talking, Nanaka had covered for her about her panties… even now that she'd seen Kanon on a date with rosy palms, the idol still trusted her enough to probably not tell any of the other girls what she'd seen…

But why? Kanon only knew Nanaka for an hour or two… why should she have such unfailing trust in someone who was basically a stranger?

"You already know the answer to this, Kanon…" a voice whispered in the idol's head… whether it was Apollo or her mind speaking, the slight fog in her head cleared up.

She would make Nanaka feel better if that was the last thing she'd do!

"Err… Nanaka…" the name slid off her tongue more easily, "do you think… someone orgasming under your hands… or tongue… would calm your pride?"

"Of course," Nanaka smiled at the thought, "I can't think of 'nything more flatterin' than being able to bring someone to a climax."

"Okay…" Kanon paused for a moment as she thought about it, "I'd like to change the terms for you giving me my underwear back."

"What do ya have in mind?" Nanaka looked confused.

"I want you to make me climax… then you can give me my underwear back…"

A fresh blush stained Nanaka's cheeks, but Kanon's face remained determined.


Two stories down, Chihiro had made it down to Tenri in record time… well, to the pillar Tenri was hiding behind…

"Chihiro-san, what do we do?" the girl looked to the door helplessly, indicating to the door… while it wasn't rushed, there were definitely too many people for the girls to enter undetected.

Chihiro didn't respond, as she pressed her head against the pillar… they could wait for the people to start going, but there was no guarantee that the bathroom would ever be completely empty.

"Tenri-san, how did you know that Katsuragi is in this bathroom?" she turned to look at the girl who had her back to the pillar, sliding against it nervously.

"I-I heard two boys talking about someone holed up in one of the cubicles and making beeping sounds…" Chihiro chortled… that sounded very much like it would be Katsuragi.

"Well, that is probably him," Chihiro sighed as she watched the foot traffic… how could they get in now? Maybe they could walk in like they owned the place… or she could scare them off.

After thinking a moment, the former idea did sound more inviting to her… just saunter in, somehow convince Katsuragi to open the door of his cubicle and pull him out of the bathroom to talk about what happened.

She turned to look at Tenri, who still looked terrified.

"You can wait by the stairs, alright?" Chihiro took a deep breath, "I'm just going to go in, pull him out, and then all three of us talk."

"A-are you sure, Chihiro-san?" Tenri asked worriedly, "I feel I should be helping you too…"

"Just scream if any teachers come because I could get in trouble going to the wrong bathroom," Chihiro said after a pause. That sounded reasonable, and Tenri seemingly agreed, as she went to the stairwell. Teachers were more likely to come from that side.

Chihiro, on the other hand, came out of her hiding spot and made a determined beeline to the bathroom door. She could feel the looks of the boys around her, but no one seemed to want to stop her. Unfortunately, her relief came too early when she nearly opened the door in someone's face.

"Yo, Kosaka…" the boy spoke, and Chihiro fell back against her better wishes. This boy was in 2-B… though what was his name again… Makabe, was it?

"Yo, Makabe," she greeted as smoothly as she could muster, "if you'll excuse me…"

The boy put out his arm ahead of her against the door frame, blocking the entrance.

"This is the boys' bathroom, you know…"

"Of course I know," Chihiro rolled her eyes, "I just need something from there, quick quick…"

Makabe smirked, as something occurred to him.

"You just want to peep on me in there, didn't you?" his smile widened, "and I thought your obsession was creepy before…"

Chihiro internally groaned… people were starting to gather now.

"Don't flatter yourself, jerkwad!" Chihiro spat, "you're leaving now, so you may as well go…"

There was a collective ooh at that insult, but with the situation she was in, she'd rather not have the attention.

"Look, I'm not doing anything funny there…" Chihiro raised her hand in surrender, "I just need someone quick, then I'll leave…"

"Someone…" Makabe raised an eyebrow at her unfortunate phrasing, "fuck, Kosaka! How horny are you that you'd go into the guys' bathroom for a hookup!?"

It seemed like minutes for Chihiro to comprehend what she'd landed herself into… Makabe and a group of other high school boys were near certain she was going inside to fuck someone, and no amount of trying to convince them of her actual intentions… at this rate, her even being able to get in seemed really unlikely, or even impossible…

It was no surprise to Makabe that Chihiro seemed lost for words… or dare he say it, broken… just as well, because he hated fierce girls like her…

"I thought so…" he sneered, before leaning a little closer to her ear and whispering the next part, "and I'll be nice, even… I won't tell anyone about this if you'll meet me when I have to do my cleaning duties this week…"

For a moment, an unpleasant shiver ran through Chihiro's body… this kind of invitation felt like it would be more than him trying to pass off his cleaning duties to someone else, and her stomach clenched.

"No thanks…" she looked up, the fire burning behind them not abating at all, "I don't know what the fuck you're playing at, but I'm not game…"

The adrenaline that was coursing through her seemed to spike as she looked around at the small crowd around her.

"So you think I'm going to fuck someone in there!?" she asked rhetorically, but mostly to the pig who was in front of her, "well, Katsuragi is there, so I think I will… you wanna watch or something, bitch!?"

Makabe's face faltered as Chihiro's brown eyes burned brighter.

"You want Otamega?" a voice murmured from the crowd.

"Of course I do!" Chihiro snapped, "And if you think you're going to spread some rumours about me, you may as well get the full story…"

Keima was inside the second cubicle, so he heard Chihiro loud and clear right from the start… however, it was her words from there which sent his jaw agape, with plenty of vulgar language and descriptions vivid enough that Keima could feel his pants tenting up again and his cheeks lighting up.

For Chihiro, that speech had the desired effect too… the crowd dispersed pretty fast and Chihiro marched in, her heart beating loudly against her chest…

Except, of course, there was still that one guy, who was drying his hands. He gave Chihiro a somewhat amazed smile as she stepped in.

"Oi… which one of these is Katsuragi in!?" she asked, motioning to the cubicles. The guy motioned to it before heading to the door.

"You guys have fun," he replied in an amused tone, "and the main door has a latch if you want to use it…"

"Not that I needed that, but thank you," Chihiro responded as she waved him out… glancing up, there was a latch to close off all entrance to the bathroom, but she didn't really have any reason to use it right now…

As she caught her breath, she was still kind of impressed at how Hinoki managed to teach her something without her even being in that group being "tutored" by her…

But never mind that… she stepped up to the cubicle and put her hand on the door to kind of alert Keima of her presence… not that her entrance had been particularly subtle or quiet.

"A-are you there, Katsuragi?" Chihiro asked. When getting no reply, she tried again, "we're not here to drag you back… we just want to talk to you."

Inside, Keima was conflicted on whether to respond or not… he didn't really want to talk with any of the girls, but considering the effort that she'd put getting there, not talking to her didn't feel like an option either…

As he opened his mouth, he felt her presence move… he wasn't sure where, but she wasn't outside his door. He could hear her footfalls, but the echoing of the bathroom did little to help him locate her.

And all of a sudden, he heard a thud overhead and he looked up, suddenly seeing half of Chihiro over the partition between the cubicles, looking down at him.

Sheesh! His eyes shot open and he hastened to unlock the door.

"No, don't worry about that," Chihiro shook him off as she edged forward, "I'm just going to come in from here…"

"Are you fucking nuts!?" Keima yelled.

"That had been the plan before you ran away!" she responded cheekily… she understood full well that he was right in considering her entrance insane (which it was), but she continued climbing in. She probably would have fallen inside too had Keima not climbed on the closed toilet seat and let her down properly.

After a few moments of struggling, Keima settled Chihiro down on the somewhat flat ground of the toilet lid.

"Are you trying to give me a heart attack!?" he asked, climbing down onto the floor to put some space between them.

"Well, you weren't answering…" Chihiro folded her arms defensively, "you gave me more of a heart attack!"

She glared right back at him as soon as she let herself down, but Keima couldn't help feeling his heart soften… she'd been worried about him, and had gone to kind of insane lengths to try to get to him.

"You're insane, you know that?" he told her, but he could feel the affection bubbling in his voice.

"Well, maybe I wouldn't need to be if you actually hid in a place I'm legally allowed to enter," she responded back icily, "I was worried about you, so of course I'd go nuts trying to get to you…"

Keima himself sobered up, as he sat down on the toilet lid.

"I'm sorry to cause even more trouble… I expected that people in that class might look for me, but I didn't expect this length…"

"Thank Tenri-san!" Chihiro sighed, "only the four people who were in the curtained room knew that you disappeared, and Tenri-san was the one who figured out that you were here… I should actually call her…" she pulled out her phone from her pocket.

"Please don't…" Keima spoke just as Chihiro's phone beeped. She quickly opened her phone.

"Just your luck, because she is distracting a teacher, and I have to lock…" her words trailed off as she let herself out of Keima's stall and closed the latch on the big door before quickly filling her hands with water and spilling it by the entrance… Keima followed her silently.

"So people think it's closed for cleaning," Chihiro mumbled, answering Keima's unasked question…

Keima nodded his head… Chihiro was pretty good at quick thinking… as surprising as everything she'd done today was, he did know that she had it in her…

For a normal girl, she was pretty strange… not that she wouldn't be able to say the same thing about him.

After Chihiro completed her impromptu bathroom flood, she jumped back on the marble counter by the sinks, trying to think where to begin.

"In any case…" Chihiro turned to him, having thought up her first question, "Can you please tell me what happened which made you leave so suddenly?"

"I…" he struggled for words for a few moments, turning his head away from her, "I suck at this…"

"You… suck at this?" Chihiro repeated.

"Yes!" Keima threw up his hands, "in any situation, I've had some control of the flags, but there are no flags here! Everyone acts on their own, everyone has their own emotions and feelings, and I have no clue on the controls on my own body, let alone anyone else's…"

"I don't get it!" Keima continued… it seemed like him beginning just opened a floodgate of complaints, and he was just getting started, "I'm supposed to be helping everyone learn and experience sex, when I have no knowledge on it beyond the few eroge I've played… I may have seen what a girl's "downstairs" looks like many times in CGs, but I have no clue what I'm supposed to do with them to make them feel good… I don't even know what's happening with my own body, and I had to hear it from my childhood friend that I'm not even going to be able to show a girl that I feel good… I don't get people's hormones, or why girls can kiss girls and still enjoy it… I don't even know if I love anyone the way that they love me…"

Seemingly, it was that last admission which seemed to crush Keima the most… there was no denying that each girl that was in that room was special to him, and the thought of being there for them in a sexual sense was insanely inviting… but he wasn't in love with them…

"I don't have my virginity anymore, so what am I even going to give the woman I fall in love with one day?" he turned to Chihiro, who looked a bit too amused, considering the seriousness of this conversation…

"You know that no one expects you to do this alone, right!?" Chihiro shot…

"Maybe not, but I'm still the leader," Keima answered right back.

"Maybe you are, but the whole point of this is for us to figure it out together, and stop treating sex as some kind of taboo that we can't explore or learn about…"

She took a deep breath before she continued to the next part…

"And you say you don't understand how it works in a vagina…" Keima nodded uncertainly, "then just tell us, you nimrod!"

Keima instinctively ducked as Chihiro's hands came close, but she just grabbed onto his shoulders and looked him dead in the eye…

"If you want help, we'll help you…" her voice was barely higher than a whisper. Keima hung his head.

"But then how can I be considered a tutor if everyone is tutoring me?" he responded. Chihiro did understand that, which fuelled her next snap decision.

"W-what if… I taught you here? That way, you can learn, and no one else would need to know."

Chihiro's implications weren't lost on Keima.

"Y-you mean… on your…"

"Obviously," a rush of colour went through Chihiro's face, "you want to learn more about it, right?"

Keima obviously couldn't say no there… for all that had happened in the last ten minutes, he could feel himself calming down and his heart stopped hurting…

Also, Chihiro looked so adorable as she seemed to pull down her skirt, seemingly not believing that she was going to get to show the love of her life the most secret part of her…

For a moment, Keima kept his eyes locked on her, thinking of her proposition… of how it would feel like, exploring her body, doing the hottest research known to mankind.

Somewhere else in the building, Kanon sat on the hagoromo bed, her fingers clutching the covers as Nanaka gave her an intense look…

"Kanon…"

"Chihiro…"

"Would you lift up your skirt for me?"


Ooh, mirroring situations... That's the good shit...

This is more the buildup to the next scene, but expect some sexy times up ahead. Also, here's hoping that no one is squeamish about Yuri, coz you're gonna have a bad time. :P

So, reviews now...

The Gromm: Ooh, a first-time reviewer. Nice to meetcha.

I'm glad that you've been finding the story interesting so far. Obviously, it's pretty different from what I normally write, but I have always wanted to try something ambitious like this.

Ah yes, I did actually end up binging Sexual Education after it came out, though the resemblance is mostly due to the topic. Probably the most obvious parallel is that neither of us stray from showing sex... I was actually going to name this story Sex Ed(as that is how it's saved in my computer), but I wasn't sure if this site would have issues with that.

Also, as you mentioned it, stamina is a real issue in this story, coz this entire story is taking place over a single day... luckily, Keima knows a few magical people, so we'll need to see.

As for the tally marks... I'm definitely gonna revisit that. Thank you much for your review, and even lurking is fine with me. I'm glad that Kaminomi still has devoted fans, even though the manga has been finished for five years now.

xellos540: Oh, look, you updated KanonNomi... Oh wait, that's just a review o.O

As always, thanks for your long and detailed reviews which always make me want to reread the chapter because I forget what the hell I wrote :P

Wow, you had a lot to say about the Tsukiyo scene... in fact, on the email, it was truncated at that point, less than half way through the chapter. Ah well, at least you understood my intentions.

Though Tsukiyo being predatory... that wasn't the intention... although I'm not against that idea... *quickly scribbles on my notebook* actually, ignore me. That was exactly my intention :P

I'm a lowkey shipper of Shiori and Tsukiyo, and I love that this story lets me write about that

Nice euphemism, btw. This is the one and only time I'll actually call exercising fun.

Who knows, this might be Yui's way of getting back at certain people for making her flash the other group :P

Lol, though Eri ended up distracting Nikaidou to the point that she couldn't stop the girls from breaching the room.

I certainly enjoyed writing that kiss as long and as descriptively as I possibly could. Glad that you liked that yuriness :)

Hoo, I've never thought of Akari's experience, tbh... I guess it was probably just as mechanical and purpose-driven as the rest of her actions.

You called it... generally, I write stories in a straight line, including conflict and awkwardness where I need it, but this was the first time where it truly got real.

Though I still haven't wrapped up the RPG yet... Kanon is helping Nanaka work through her problems, Tenri is providing support and Chihiro is trying to fix this... I dunno if she's the fighter or the healer in this RPG scenario, but no mind.

Thank you for reading, and your reviews are a pleasure to read as well.

That's it for this fortnight. I hope you enjoyed this and review if you have stuff to say or suggest. They really make my day :)

Stay well guys. I'll see you guys next time.
