To Teach Math and Sex

Vizrokoth beamed with pride as she her prized creation, Kei Winters, entered the room. Jamina followed soon after, and the final in the procession, Felix. He hadn't looking forward to this, but attendance was mandatory, as the demon would enforce it. They had all eaten lunch, and all the contestants needed for this contest between them had arrived. The room itself was perfect, as it was a leftover college style classroom, with rows of built in seating and tables in a half circle, all in front of a chalkboard. Said chalkboard had already been used the prior day by Kei Winters and Jamina to resolve a different competition, which Kei of course had won.

That was the thing that Jamaina didn't realize. Vizrokoth could give someone high levels of pedagogy because skills were something she could change like anything else. It didn't matter that wanting to fuck one's students and teaching them well were incompatible traits most of the time, the demon could make them compatible. She had done so, after all, in order to mess with Jamina when they were still a man, and to punish her for her unearned moral certainty. This final competition would be the weapon she would use to break Jamina, so that she could be put back together again as a part of Felix's harem.

"There are some rules to lay down before we begin," Vizrokoth said while guiding Felix to have a seat, and the competing teachers to the desk that overlooked the room. "In order to make this more fair, there will be an additional student to act as a control. We are primarily testing your ability to teach, not your relationship with Felix."

Hailey waived at Felix to show her presence. He was happy to see her, but neither Felix or her could stop to chat, given what they were about to do. The girl was the perfect control, as while she was smart, she didn't put in excessive effort, which meant that she could represent an average student fairly well for the purposes of the exercise.

"Wait, then why is Noah here?" Felix asked while pointing to the slime girl who had beforehand been unnoticed. "She is far too smart in math to work as a contrast to us."

The slime girl smiled hearing that, and chose to answer. "In the new timeline brought by Cammy, I studied with you a lot, and that means I can judge what your baseline is. And Hailey's for that matter."

"Noah is here to inform your teachers what they should expect of you Felix," Vizrokoth said. "What you can do, not what they wish you could do. That will be very important knowledge for both of them, because Kei Winters and Jamina each have one hour to teach you something that you will take a thirty minute test on afterwards. Do note they also have to teach Hailey, not just you, the concept."

That announcement allowed Vizrokoth to teleport out and watch proceedings from afar. Her presence could bias the result in multiple ways. While this wouldn't ever be a fair contest, the demon needed it to be as close as possible for Jamina's sake...

Z dragged Nox to the kiosks to acquire two items. The first was obvious, as the oni spent 1500 BP to acquire the details on the next challenge. Upon grabbing the scroll and reading it... Z sighed.

"Great, a challenge built around finding Felix, and bringing him back," Z said. "And I happen to know that you don't even remember much geography, much less anything about navigation. Which means in this contest, I'm stuck trying to be useful to a group that's probably scared of me. What a fucking joy."

The oni tried to cheer herself up by looking for something to train Nox with. However, Z quickly realized that with only 500 BP, that was going to be a tall order. There wasn't a discounted sexual training kit after all, or at least, not one with what she had in mind. It was something to talk about with the demon later, because it was an odd omission for Harem Hotel. However she did eventually find a dildo that was meant to be like Felix's cock, and would do nicely for what she had in mind. She purchased the item, and then turned to the goblin, grinning.

"Alright Nox, today is sexual training," Z said while approaching the goblin with the dildo. "Here are the steps you are going to follow exactly. You are going to masturbate with your hands until you orgasm once. Even your utterly pathetic knowledge of female anatomy will not lead you wrong here, because you are a goblin, which is the easiest level of difficulty when it comes to female pleasure. Got it?"

Nox nodded, while starting to tear up. Even she knew where this was going, and the thought of penetration, even if it was by an artificial sex toy, disturbed her. It would remind her a lot of her lost dick after all, and everything she had lost over her time at the bunker. Z, if anything, thought this bit of training could help alter the goblin's personality in a way that would make them easier to train going forwards. After all, ego destruction did wonders for making students pay attention.

"Once you have gotten yourself wet from cumming, you are to practice inserting this dildo again and again into your pussy," Kei Winters said while shoving the dildo into Nox's hands. "Get to the point where you can comfortably fuck yourself with it to orgasm, and then keep doing it until penetration seems natural. I will pick you up when it is time to stop. Got it?"

Once again, Nox nodded, tears flowing freely.

"Good," Z said. "I'm going to go get myself ready for Felix, while you are going to hang out in whatever room you can find where you can hide your orgasms..."

What was shared to Jamina about Hailey and Felix put her in a bit of a tough spot. Hailey was, as expected, fine. While she hadn't taught the girl, what she heard suggested a student who probably wouldn't live up to her obsessive standards, but would do fine, especially with additional effort. Felix by contrast... was a gigantic middle finger to everything she believed in as a teacher. From her side of the timeline she saw a student scraping by with a passing grade, and that had little to no chance of passing her final in the class. Jamina thought this was because Felix wasn't studying enough, or otherwise lacked sufficient motivation to focus enough on the subject matter.

If Noah was telling the truth, and even Jamina had to admit she probably was, there was no level of studying that got Felix to more than a C. Noah described someone who was always the last to leave the study group, and who always had to study math the entire time regardless of his grades in other subjects. This level of effort in the study groups was because Felix had found, from bitter experience, that he couldn't study solo with any meaningful level of effectiveness, with the exception of unsustainable levels of cramming. The slime girl went onto explain that if Felix seemed inattentive, tired, or similar, it was because for every test day, he had to cram the prior night to barely get a passing grade. He knew this because if he didn't cram, which he couldn't do for surprise quizzes, he would just fail. That this level of effort resulted in such poor results flew in the face of the fundamental philosophy she had as a teacher.

With this knowledge in mind, Jamina had to scrap her intended lesson plan, and start over. Felix needed to go over the fundamentals, potentially from a different grade, if he was this dependent on brute **** memorization. So, she chose a concept from 11th grade math rather than 12th grade, as it was more likely that Felix would be able to learn it. It would make things a breeze for Hailey, and she was having to dumb things down, but at this point she was ****. Her entire approach to teaching was not going to work with a student that had this many limitations.

Once she started her lesson plan with Felix, things initially went fine. Without being in the school, and with it being such a narrow slice of topic that he should already have known, they were able to progress. However, as they got further, and Jamina had him try to practice what she taught, she realized a massive problem. His accuracy on longer problems was atrocious, no matter how many times she re-explained the underlying concepts, or worked through the problem with him. Realizing she wasn't going to be able to fix this issue in the time they had, even if she only taught Felix, she chose to just re-iterate the underlying concepts as best she could in the hope that maybe he could the shorter problems well enough to pass.

The actual test started and initially, Jamina had hope. Hailey only took ten minutes to rip through it, and upon grading it, saw that outside of a clumsy error, she had aced it. This wasn't necessarily a mark of her skill so much as the ease of the test, and she only had one error. Even though the teacher had only been able to do a quick refresher with her, it was enough. She got a solid 92 on the test, which was certainly passing even by Jamina's harsh standards. Everything was looking up as while Felix was taking longer, it didn't seem like he was failing.

But then Felix ran out the clock. Not on purpose, but because he got stuck on a problem, and didn't notice until it was too late how much time he had wasted on it. He tried to rush through the rest of the test, but even with that, he wasn't even able to finish. Grading it for Jamina was ****, because in effect, she was grading herself, and every teacher Felix had before her that had failed. Even if she was being generous, and decided to ignore where he wasn't able to show his work from being pressed for time, Felix only got a 70, another barely passing C. If she graded more harshly, he would fail at a D, from not showing his work and other sloppiness.

By the time Jamina got done, it took everything she had to not bawl her eyes out. It hadn't mattered that she paid more attention, because whatever Felix had wasn't surmountable by effort, or one on one teaching. It made her wonder how he had even gotten this far, but then she considered that holding him back wouldn't do anything unless the underlying issue was addressed. All of his prior teachers could've been pressed for time, and in that case, she could easily imagine they just waived him through as an act of mercy, or just to make him someone else's problem. As much as she critiqued that attitude in life, she realized from Felix why this could've been necessary. If a student wasn't going to be able to learn the material either way, what was the point of forcing them through it? But that lesson was one of the most bitter pills she ever swallowed...

Kei Winters took a different approach from Jamina. She knew he had a disability, and she knew she wasn't going to be able to fix it in the time she had but she might be able to work within its constraints. What Noah described was a kind of student she knew about: a student burnt out from having to devote massive amounts of effort and willpower for paltry results. The key in such cases was to get the extent of the damage, and find a good starting point they could work from while rebuilding their confidence. Hence, a quick diagnostic test was in order. It would cut into her time, but she could get Hailey up to speed while Felix completed it.

While Felix took a quick diagnostic test, she went over her plan with Hailey. They were going to do something at grade level, it was something that she had probably studied for in her first semester, and to not worry about it. Whatever the result of this contest was, it wasn't going to impact anyone outside of Jamina and Kei Winters, because this was meant to resolve a dispute between them. Once the conversation ended, Felix made a motion to show he was ready for the lesson.

Upon getting the diagnostic test results, Kei Winters realized that Felix had a very specific issue: His working memory. His accuracy kept collapsing in longer problems, even when he took extensive notes, because he just couldn't hold the problem in his head long enough to complete it. She was very lucky this was his weakness, because she did have a tool to deal with this. It wouldn't fix everything, especially as she knew this wasn't likely to be the totality of his problems, but she could at least stem the damage.

"Felix, do you know what mnemonics are?" Kei Winters asked.

"Yeah but..."

"We're going to use some today," Kei Winters said. "I'm not going to promise miracles, but it'll help you here."

What followed was not a miracle, but a gradual improvement in Felix's ability to complete longer problems. She taught a laser focused set of mnemonics for the problems at hand to relieve his overwhelmed working memory. It wasn't going to transform him into a math genius, but it made him more confident with the topic, and less stressed over it. That last point was important, because Kei Winters could tell that Felix's relationship with math at this point was more like an abusive relationship than a school topic. Hence, made sure to emphasize to him that this wasn't worth stressing over, and she even massaged him from time to time while he worked so that the problems weren't so insurmountable.

The actual test went fine by Kei Winter's standards. Hailey finished in, again, ten minutes, and Kei could tell from just looking at her test that she aced it. The girl was an easy student for Winters to teach, with no real weaknesses to account for, other than just knowing she wouldn't tolerate anything that wasted her time. If she had to teach her for real, she knew she could've gotten the girl on her side by just removing impediments to her free time. As for Felix?

Felix didn't achieve a miracle, but his test did go better. He was able to finish within the time limit, and his final grade of 75 was acceptable given the circumstances. If Kei Winters was his actual teacher, she would know, once they had a 504 conference, and got his disability sorted, that he'd be fine. She could picture the parent-teacher conference where she'd explain to his mother that while her child had difficulties, he'd be able to get a good job, he just needed to get his adaptations in place before college. It just so happened that would include many private after school tutoring sessions, and maybe he should come over on the weekend...

Kei Winters shook herself from the fantasy. That type of thing could wait until tomorrow, when her victory was fully cemented...

(WARNING: Lots of anal and rimming in this section. I know that isn't everyone's thing, so if it isn't, I give you permission to just skip to the next chapter if its available once you get here, or maybe just rapidly skim this for any plot stuff you care about.)

Felix lay on the bed in master suite, decompressing from the math earlier that day while waiting for Z, and if he understood the rules correctly, Nox. Cammy left, explaining that she didn't think the oni would like her presence, and because she didn't want Felix's first foursome to be with someone he barely knew. He didn't know if he was ready to deal with his former bully in the form of a goblin, but perhaps Z being there to restrain her would be enough.

Once the master suite door rang, Felix ran to answer it. He then backed away as Z, and Nox entered the room. He had seen the goblin at breakfast many times, but hadn't paid much attention to her. The knowledge that she was under the strict control of the oni helped, but he had too much to do before this day to want to confront his former bully, or even really acknowledge him.

"Nox, you've been a naughty girl," Z said. "Beating up Felix, over and over, all because he had something you didn't. You know what that is?"

Initially, the goblin didn't answer, but after working herself up, she said, "A girlfriend."

"Yes, one that genuinely loved him, and fucked his brains out all the time," Z said while bending over to talk to Nox. "Even before you knew about her, you mocked and belittled him because you liked how it felt. You wanted to be on top, to win your daddy's approval. How has that gone for you?"

Nox didn't even bother trying to answer, she just went into a corner, and started to cry. The tears of someone who has been tormented on a level they didn't even know was possible, and that made the reason they had been treated that way painful by extension. While hard to watch, this had the intended effect of assuring Felix that he had nothing to worry about from the goblin tonight.

That was good, because all the while, Felix had been staring at Z's ass while she was bent over, which had somehow gotten even better than the last time he had seen it. Even while she was wearing gym shorts, he could tell the oni's ass had gotten even bigger in the most glorious way possible. The only thing he was worried about was that maybe the shape would be less than optimal, but that got fixed when she realized what he was staring at, and dropped her gym shorts which had no underwear. Once again, Felix was staring at the sweetest ass he had ever seen, with the ripples each butt cheek made while Z moved around alone making him painfully hard.

"I see you still love my ass," Z said while standing up to strip out of her tank top and bra. "That's good. Go to the bed and wait for me while keeping your eyes on my ass where they belong."

While Felix walked to bed while keeping his eyes glued to Z's awe inspiring butt cheeks, the oni went over to the goblin, and issued a single command. "If the urge, no matter how minor, strikes you to masturbate, do so. But unless you're looking at Felix's dick, you're not allowed to cum."

With that devastating set of commands, Z turned to face Felix. He saw that her breasts had also gotten larger, and were still very perky in a way human women couldn't compete with.

"Alright, it's time for you to do something that I know you badly want to, but were scared to, and that it felt humiliating to ask," Z said while crawled onto the bed on all fours. "You're going to kiss, lick, and suck my ass."

Such a blunt, bold declaration made Felix wonder whether he could cum from giving oral sex. He got behind her, grabbed her butt cheeks which felt as good in his hands as they looked, and kissed Z's ass.

"Such as good boy," Z said. "You've got one hell of a prize waiting for you if you just follow my instructions, and get me off."

Unlike last time, Felix didn't start slow because of being scared of Z. Instead, he started slowly because of just how taboo his actions were. He was sticking his tongue in someone's asshole, and was loving every second of it. Soon, his tempo picked up, and by following the oni's instructions, drove her nuts.

"Yes, that's a good boy, kiss my ass!" Z screamed.

Felix loved this, and he was too horny in the moment to think about what it meant. He loved Z grinding her massive, glorious ass on his face, and how her ass was so large that it was easy to bury his face in her asshole. It should've disgusted him, but it didn't, and instead he was thrilled how much his partner could enjoy his tongue.

"YES!" Z's scream of orgasm was loud, bestial, and caused her ass to quiver in a way Felix loved.

"Alright," Z said while pouring lubricant into her asshole, "You've earned a very special prize. You get to fuck my ass, and you get to do it while your former bully watches, masturbating helplessly."

That convinced Felix he was in heaven. Once she was done lubricating her butthole, Z motioned him to lay on his back. Once he followed her instructions, the oni crawled down to his crotch, turned to face him, grabbed his dick with her hand, and then sat on his dick with her ass. The tightness that followed caused him to cum almost immediately, in one of the most powerful orgasms he had experienced in his life.

"Aww, already?" Z asked teasing him. "Don't worry, I can get you hard again really fast."

It should've hurt Felix to get hard again so fast, but the pain must have been overwhelmed by the heavenly sensation of his dick being in Z's asshole. Unlike human women, she had been able to take his entire dick in a single motion. Just gripping it with her butt muscles was enough to get him fully erect, and once she started riding his dick with her ass, he was so thankful for having a longer refractory period. He never thought **** orgasm could feel so good, but it did when it was from the oni's ass.

"I once had a human man beg me to stop," Z teased. "But as I told him, I'm not going to stop riding your dick with my ass until I cum again..."
