This is what happened on the night Yuuto spent at the Yuugaoze mansion.
Unknown to him, the room Miyako took Yuuto to was the master bedroom. In other words, Miyako's room. After bringing him there, Miyako left Yuuto alone for a few moments.
Thinking this was simply a luxurious guest room, Yuuto began to undress. He planned to sleep in his underwear, since he didn't have any sleepwear with him.
As for Miyako, she also went to change into her sleepwear, but hers was a bit special. She put on her sexiest panties, it was basically a series of black strings connected to each other that did little to hide anything, but did a lot to show off her sex appeal. Over that, she put on a pink nightgown that was mostly transparent.
Once she was prepared, Miyako returned to her room to find Yuuto in his underwear. She hadn't told him her plans, but she was happy to find him like that.
"Oh my, I see Yuuto's also ready~"
Yuuto was clearly surprised to see Miyako's appearance, so it took him a second to react. But Miyako found that cute.
"M-Miyako, what's this?"
"Mm? I'm sure Yuuto can guess. Truth be told, I planned to start this at the bath, but Yuuto got shy and ran away. But I guess that means I get to have Yuuto all to myself now. I even brought you to the master bedroom."
"I knew this was too much for a guest room!"
Miyako had locked the door behind her, so Yuuto couldn't escape. Not that he'd have a reason to want to.
She approached him. Yuuto took a step back mostly out of reflex and ended up sitting on the bed. Miyako tried to kiss him, but he dodged her.
"W-wait. I mean, in the bath, Miyabi didn't really seem comfortable with us so…"
"Yuuto, let me teach you something: when you're alone with a girl you can't just bring up other girls like that. I suppose it works a little differently if you have 2 or more at once, but you get the general idea."
"No, what I mean is-"
"Let me explain why I'm doing this first. You see, Yuuto, I heard about what you and the girls had to do to make the new magic stone for Reina. While you did achieve your objective, I thought you were 'lacking' in parts. I gave tips to the girls, so I figured it was only right to also help Yuuto."
Miyako wasn't lying. After Yuuto left the bath, she took this chance to talk with Lizel and Miyabi about their time at the love hotel. Miyabi was uncharacteristically embarrassed, but between her and Lizel, Miyako was able to get a good idea of what had went on.
That's not really to say that Yuuto's sexual prowess are lacking. Far from it, for the average person, he was pretty good. However, he was still a far cry from the usual Lovers Candidate, who could literally spend their whole day fucking non-stop, or so Miyako told Yuuto.
Considering Lovers Arcana gains power from doing perverted stuff, it's in Yuuto's best interest to become a sex-beast.
"Besides, I've been hearing about an alliance of Devil King Candidates. If that kind of thing is happening, it's all the more reason for Yuuto to become a master at handling women. You can just seduce all the female Candidates, that would make it much safer for all of you."
"Y-yeah, I guess you're right…"
Yuuto thought about what Miyako said. Despite everything, Yuuto was still a 16-years old boy, so there was a lot of appeal in the idea of being able to solve all his problems with sex.
And Yuuto also wanted to make his Cards feel good during Healing Lovers. Hearing Miyako found him lacking was a big blow to him, so Yuuto really was considering asking her to teach him some things. If nothing else, surely an adult woman like her could give him a few tips.
"Well, you can pick whatever excuse you like. I just want to do perverted stuff with Yuuto~"
"So it was all an excuse?!"
None of what Miyako said was a lie, but it was all secondary to her. She would still be trying to do this even without all that.
It had been years since Miyako had last felt lust like this. She was no pure maiden, Miyako lost her virginity while still in high school, and had tried just about a little bit of everything before getting married to Miyabi's father. Once married, she was faithful, but that was no longer the case. So, as far as she was concerned, this meant she was free to get on with whoever she wanted.
Without meaning to, Yuuto had rekindled a fire in Miyako. She knew about the whole thing where he should avoid having sex for now so she was willing to give up on that for tonight. But she was only willing to compromise on that, there were still a lot of things that could be done without penetration.
"And off you go."
"W-woah!"
Miyako took off her nightgown, leaving her naked except for her panties, which barely counted.
Miyako's breasts shook. They were big, huge, the biggest Yuuto had ever seen. They clearly won against Miyabi's, which now fell to Yuuto's second place in size.
"Come on, touch them."
Part of Yuuto still wondered if this was fine. He's a man, so what he wanted to do was obvious enough, but part of his rationality still remained.
But that came crumbling down when Miyako took Yuuto's hand and placed it on her breast. Yuuto convinced himself that it's not like he could escape anyway, so he might as well take this chance and learn a few things. It's all for the sake of learning.
Yuuto started groping Miyako's breasts. He was amazed with how soft they felt. It really felt like Miyabi's, but leveled up.
His fingers sank into her soft flesh. It felt like playing with dough. If any part of Yuuto's rationality had survived until then, it was gone now.
"Mmnn, yeah, there's no need to hold back. Here, Yuuto, give me a kiss."
They kissed. It wasn't the first time Yuuto and Miyako kissed, but that time, when Miyako first arrived at Yuuto's house, and now are very different.
Then, Miyako simply wanted to get her daughter out of danger. Now, it was just lust that was guiding her actions.
"Nn, chuu."
"Mmm, nn, nnnn~"
Yuuto was still a little timid, but Miyako wanted the full serving. She took the kiss as deep as she could and even put her tongue inside Yuuto's mouth.
Not just that, she was actively getting as close to Yuuto as she could. It got to the point she forced him to lay down on the bed and she got on top of him.
But of course, Yuuto couldn't just remain passive forever. It was time he began his counterattack.
Groping Miyako's breasts was all well and good, and while she was feeling pleasure, Yuuto was clearly the one being pressured. In that case, it was time to change strategies.
Yuuto let go of Miyako's breasts. Instead, he used 1 hand to make their kiss even deeper as he went for the attack. His other hand went down to Miyako's butt.
"Mm, so Yuuto really does know what he's doing~"
"I'm trying my best."
Miyako's panties didn't cover much, but Yuuto still got them as much out of the way as he could while groping her ass. And their kiss also continued at the same time.
But Miyako also wasn't one to just take things. She started rubbing her crotch on Yuuto's. Their underwear was in the way, but it still felt good for both of them.
Their fierce battle continued on for almost half an hour. The only reason it stopped was because Yuuto reached his limit.
"! Mmm!"
"Oh no, you don't. Yuuto's past the part where you can just dirty your underwear and call it that."
Better put, Yuuto would have reached his climax, had Miyako not suddenly stopped.
After what happened at the love hotel though, Yuuto found out he'd not a fan of edging. He understood it would be hard for him to continue after he came, but at the same time he really didn't want a repeat of that.
"Say, Miyako… can't we just continue until both of us finish?"
"Nope. Didn't I say I'd give you a lesson? While that was just an excuse, I can at least give you a few tips. The first one is that language is important, there's no problem with saying dirty words in bed, even more if you don't usually say them. So, want to try again?"
Was Miyako really intent on making this a lesson? With every second that passed, Yuuto calmed down, and he didn't know if that was good or bad.
"Miyako, I-I want to c-cum. I want us both to cum!"
"Hmm, that's good for a start. And how do you want to cum, Yuuto?"
"T-that's…"
Yuuto didn't really mind what Miyako did to make him cum, but his eyes naturally went for her breasts. And she didn't miss that.
"You have to say it or I won't know~ maybe Yuuto wants to put it in? You can't, but I won't stop you~"
"Your breasts! I want Miyako to give me a titjob."
For a second, Yuuto considered what Miyako said. He could put it in, and she wouldn't stop him. But he stopped himself. If he's going to give in, it has to at least be during Healing Lovers, or he wouldn't be able to face Lizel and the others after.
So he settled for the next best thing. Of course, there was the problem that he said he wanted them both to cum, which was true, but he didn't really know how he'd make Miyako cum with a titjob.
"Fufu, alright then. Take off your underwear."
Miyako didn't seem to mind as she took off her panties. Yuuto also took off his underwear, revealing his rod at its full size.
She didn't mention it, but Miyako was pretty happy with Yuuto's size. Yeah, she'd seen bigger, but those were ogre-like mixed-blood devils. As far as normal sized humans/devils go, Yuuto was on the bigger side of things.
Miyako's mouth watered, which was just perfect. The main attractions would be her breasts, but she needed some lubrication first. Besides, she wanted a taste.
"Aaaaahmmm."
So she took him into her mouth. He could go down her throat if she tried swallowing him to the base. And she also enjoyed his taste and smell.
Miyako kept licking and sucking Yuuto's member. She wasn't going too fast since she didn't want him to finish just yet, but she also enjoyed watching him struggle a bit.
"Mm, there, that should be good enough. Now time for lesson 2, Yuuto?"
"Eh?"
There's more?! Yuuto wanted to shout. At this point, it was more like Miyako was toying with him.
"Yuuto knows about the difference between humans and devils' magic circuits, right? I want to focus on the fact that devils have gender-specific magic circuits. Can Yuuto guess what I'm getting at?"
"N-no."
"Basically, it's not uncommon for devils to also use their magic circuits during sex. I know Yuuto's human, so you lack the magic circuits for that, but I figured Yuuto could try something. Maybe sending mana to you dick? I'll give you a few minutes to try and get some results."
And she was going to let him cool off on top of that?! Miyako was a strict teacher!
It seemed like, if Yuuto hoped to ever finish, he'd have to do as Miyako said.
As he kept his trial and error going, he asked Miyako about this 'technique'. Like, if it even worked on humans and stuff. Surprisingly, she told him that she heard about a number of male devils that tried it on human girls, and it apparently made them basically into sex-slaves, though she doesn't know if this is an exaggeration or not.
But from her own experience, it could make sex much more enjoyable if done right. Of course, she didn't expect Yuuto to learn it all today, just some basic stuff. It was sure to be a nice surprise on his next Healing Lovers.
Despite all of Miyako's excuses, she was right in saying this could become an important ability for Yuuto. Though, at the time, no one could have imagined just how much.
"Time's up~ let's see what Yuuto managed."
Without much warning, Miyako put Yuuto's member between her breasts. He didn't know if he should be happy about it or if he should actually try to focus and learn what Miyako talked about.
Regardless, she didn't give him much choice when she began moving her breasts up and down.
"Hmm, not bad. But I think Yuuto can still do better."
"It's hard you know!"
"Do your best, Yuuto~"
How could such a beautiful woman look so devious?! She was a devil though.
Yuuto was forced to continue trying to learn the technique Miyako had introduced to him. He even tried asking the Arcana about it, but she couldn't help him with that.
Luckily, Yuuto's quite good with magic. So it didn't take him much to learn how to focus his mana on certain parts of his body. Of course, he still had to watch out so he didn't fall unconscious from using too much mana, but otherwise it wasn't a bad first try for something he'd just heard about.
"Nnn, Yuuto actually managed to do it. I was just planning to play around a bit, but now I have to actually get serious."
Miyako finally understood why Miyabi felt frustrated at how quickly Yuuto learned.
To give an example of what was happening, normally, a titjob like what Miyako was doing for Yuuto gave pleasure mostly to the man and only a little to the woman. However, Yuuto's mana was directly stimulating the magic circuits on Miyako's breasts.
In other words, it's as if Yuuto was directly stimulating her erogenous zone. Needless to say, it felt good for Miyako, but she wasn't going to let Yuuto beat her at her own game.
"Aaah! Miyako!"
She was an experienced woman, and he had only recently started getting sexual contact. Miyako could make Yuuto cum with ease.
But even so, Miyako still felt like teasing Yuuto, so she had him last as long as he could. She sped up and slowed down the movements of her breasts to make the most out of this.
Unfortunately, nothing could last forever. Yuuto eventually couldn't hold back and released his cum on Miyako's breasts.
"Did you feel good, Yuuto~?"
"Yeah…"
"Great. It was good for a first round. Now let's go for the next one. It's my turn to cum now."
"Eh?"
That's when Yuuto realized, he hadn't made Miyako cum. He had promised her, but ended up finishing by himself first.
Though, to be fair, it was because Miyako herself didn't allow it. But it didn't matter. Miyako wasn't letting Yuuto off before she got what she was promised.
"Fufufu. Yuuto has to get his balls working overtime if you want to get dirty with lots of girls. And if Yuuto runs out of mana, I don't mind going the classic way~"
Unexpectedly, this would become one of Yuuto's hardest battles until that moment. Thankfully, he managed to make Miyako cum right before running out of mana.
Yuuto slept like a log that night. But he awoke in an unusual way. He felt a strange sensation on his lower body.
"What?!"
"Good morning, Yuuto."
Yuuto woke up to Miyako sucking his dick. That was certainly pleasant, but a fear he'd have to use all his mana again rose up in him.
"Don't worry, this is just a good morning blowjob. We'll save the next lesson for another opportunity."
He didn't know whether to be happy or fearful that there would be a next time, but he didn't have time to figure it out.
Miyako sucked and licked all of Yuuto. It made him wake up, but it also felt dreamy at the same time.
Knowing Yuuto would like it, Miyako made sure to be very noisy as she sucked him. He thought it might be dangerous and that someone might find them, but Miyako knew that the rooms had good sound isolation, so there was no real danger.
But still, she thought about Miyabi finding out… and it got her excited. Miyako began thinking of maybe one day sharing the bed with Miyabi and Yuuto, and she started playing with herself. Maybe she'd even get to see her grandchildren's conception.
"A-aaaah! Miyako, I'm-!"
By the time she noticed, Yuuto was already close to finishing. Miyako had also played with herself a little too much, so she was unable to stop the end from arriving earlier than she wanted.
"Mmmmm,nnnnn!"
"A-aaaaa!"
Without meaning to, Yuuto put some mana on his cum, making it essentially like an aphrodisiac. Miyako climaxed from swallowing it and from masturbating just before.
They both needed a second to rest. But Miyako also used this chance to think over her previous thoughts.
"I'll need to butter up Miyabi."
"What?"
"Nothing~ I'm going ahead first to make sure the coast is clear for Yuuto."
No one noticed anything wrong and the day followed as normal. During breakfast, Fleminar would inform everyone that she finished with Reina, and Reina Morioka would soon be presented to everyone.
But that was only the first time Miyako gave 'lessons' to Yuuto. Of course, she also gave some tips and general consultation to all of Yuuto's Cards going forward, essentially becoming Lovers' Sex Consultant, and that role would last until the end of her days.
But that is a story of the future, so it's best left for then.
