I used Transite to teleport to a certain place.

I wasn't invading a top-secret facility or anything like that. Rather, I was visiting a normal home I had even visited before.

Currently, I was in Nagasawa-sensei's place.

"Huumm🎶 humm🎶"

Nagasawa-sensei herself was taking a bath. I knew that because I had spent a good while here, before summer vacation, when I got some horrible grades because my memories were still sealed at the time. So I learned a bit of her habits during that time.

I didn't choose this timing for any perverted reasons, I just needed to come here without Nagasawa-sensei knowing it. I could have come here later, when she was sleeping, but I figured it would be easier to explain myself if I were to get caught now rather than if I woke her up in the middle of the night.

"Found it."

Nagasawa-sensei wears glasses, but she obviously doesn't bathe with them. I found her glasses in the changing room.

These glasses were my objective. No, I wasn't here to pull a prank or anything like that.

I was here to apply a certain spell to Nagasawa-sensei's glasses that would allow me to project anything she saw. It was basically magic for spying.

The reason for that was simple, it was to obtain information from Fleminar. Basically, it's the "leak" she said when she visited Lovers Mansion a few days ago.

Nagasawa-sensei is being taught by Fleminar, so by doing something like this, I can get information without Hierophant or anyone else knowing. Of course, it would still be better to have her help me directly, but I have to take what I can get.

I didn't notice it at first, but a few days ago, when I was doing Healing Lovers with Swordia, I basically used the Telek spell without the magic formula.

Telek is a spell that allows the user to basically move things with their mind, but if you want to put it another way, you can say it creates arms and hands out of mana.

With Swordia, I had my mana take the shape of my hands and penis and moved them apart from the real thing. There were differences, but it was clearly similar, and I knew it was possible because of Fleminar.

Fleminar uses magic without the formula, but she never told me how to do it. Recently, I've been trying to learn more about magic formulas. These studies will probably become important weapons in the future, but right now I've hit a wall.

So I need Fleminar's knowledge, but I don't want to involve her in my fight against Hierophant, and it would also be troublesome if Hierophant were to figure me out and make countermeasures. So, for now, I'll just spy on Nagasawa-sensei's lessons and see what I can learn from there.

I've prepared a thin transparent film that's engraved with the spell I need. I could do it directly on the glasses, but there would be a risk of that making them unusable and then Nagasawa-sensei would have to switch them. Like this, there's less risk of something going wrong.

Well, I say that, but I just noticed another risk, a more immediate one. I don't hear the shower running anymore.

Just as I turned around to look, I saw Nagasawa-sensei swinging a showerhead at me. Luckily, she's not much compared to my usual opponents, so I was able to defend myself even though I noticed quite late.

"Please calm down, I can explain."

"Eh? Yuuto?"

Noticing it was me, Nagasawa-sensei put the showerhead back in place. Then, she picked up her glasses and confirmed it really was me.

By the way, maybe because of the surprise in seeing me when I shouldn't be here, she forgot she was naked. I'll keep my mouth shut for now. I wouldn't be a man if I didn't commit the image of such a beautiful woman to mind.

"Why are you here, Yuuto?"

"I'll explain everything properly."

I told Nagasawa-sensei about basically everything that had happened since the Labyrinth Battle Royale. As far as normal people know, that was the last official event of the Devil King War, so she shouldn't know anything further than that.

So I told her about how I took in Rinne and Hisoka and how they were being targeted by their families. I also told her about what I suspect was an attack by Hierophant a while back, and how everyone was currently busy preparing for when the Devil King War restarted for real.

And lastly, I explained to her why I came here and how Fleminar's knowledge could help me, and I also told her that I'd put some spy magic on her glasses.

"That's… I thought everything was so peaceful, but to think such a thing has been going on in the background. If this can help Yuuto, please go ahead."

Nagasawa-sensei gave me her glasses. I finished applying the magic film to them, and Nagasawa-sensei confirmed that she couldn't notice a difference, and I confirmed that the spell was working.

This is also one of the reasons why I chose to come at this timing. I knew I could convince Nagasawa-sensei if I was caught, but I also knew from experience that she got a little grumpy after being woken up, so during the bath was a better time than at night.

Being able to see her naked was an unexpected bonus. She is quite pretty.

"Thank you. Now, there's just one thing left to do."

"... You will seal my memory, right?"

Yes, that is the next step. I can't let Nagasawa-sensei know about this, that's why I tried to do things stealthy.

It would be more helpful if I could get Nagasawa-sensei to get specific information for me, but it would also be much more risky for her. It's not like this method is free of risk, but it's easier for her to be overlooked if I'm "using" her, rather than if she's cooperating with me. For that, her memory needs to be sealed.

It's not an uncommon method. For example, if a child suffers an accident and, for whatever reason, can't use magic for some time to recover, it's easier to seal their memories about magic than to explain everything to them. I myself had my memories sealed once, as I mentioned before.

I'm basically going to do that to Nagasawa-sensei. I'll seal her memories and, after everything is over, I'll unlock them. Well, keeping them sealed is also an option.

The most troublesome part is the prerequisite for sealing memories. … Or rather, isn't this a good chance to get rid of some pent up stuff from the time I spent here?

I have to admit that a darker part of my heart thought that. Might as well. I began undressing.

"W-what are you doing?!"

"You know what needs to be done to seal memories, right? Don't tell me you've bathed with a student before."

"Obviously not! I've never even bathed with a man before!"

Oh, all the better then.

Memories are such abstract things that it's hard to deal with them even with magic. In the example I used before, the child would forget everything about magic. I could do something similar here, have Nagasawa-sensei forget about me, but given that she's my teacher, it'll be easily noticeable when she starts acting differently towards me because she'll get some weird feeling every time her mind tries to remember. That also means I can't do something like sealing her memories of her giving me her glasses or of seeing me in her home. I have spent some time here before, and during that time I have grabbed her glasses on occasion.

But there is a different way to seal memories, and that is to seal a specific one. Well, it's more like putting multiple restrictions on the first type of memory seal to get only a specific memory. In Nagasawa-sensei's case, I'm going to seal her memories of taking a bath with her student and taking a bath with a man, which will seal this specific moment. By doing it in the bath as well, I'll be able to connect her memory of before she found me to whatever comes after. It was a coincidence, but it was quite lucky.

And, like I said, it's also a way to get rid of some pent up stuff. I spent a week here only being able to study without being able to do anything perverted before summer vacation. Just thinking of this place makes me feel pent up. It's time I clear some grudges.

Well, Nagasawa-sensei isn't my Card or anything like that, so I'll try to reel it back a little.

Nagasawa-sensei knew that it was necessary for sealing memories, so she resigned herself and came into the bath with me. By the way, it seems she finally noticed she has been naked this whole time, because she blushed a lot.

Nagasawa-sensei's bathing room was more like a shower room. And obviously, it was nowhere near as spacious as Lovers Mansion's, so it was really cramped with the two of us there.

But of course, that worked as an excuse for us to stick close together.

Nagasawa-sensei is a very beautiful woman, and, while she might not look like it when she's dressed in her usual teacher clothes, her body is full of mature charm. Her breasts and butt are fairly big, and now I'm getting to see them firsthand. I might have trouble paying attention in class going forward now that I've seen her naked.

Nagasawa-sensei seemed to be busy looking at my body, so I turned on the shower. It seems that the feel of the water brought her back to Earth.

"Um, Yuuto, what exactly do you plan to do?"

"That's a good question… I guess I'll just go with the flow."

"What does that mean?"

"Basically, I won't do anything you don't want. Just a normal bath with us together should be enough for a memory seal. But, if Nagasawa-sensei wants more, then I won't deny her. It would be technically better for the memory seal."

I don't want to force her to do anything, but it is true that I have some pent up urges I'd like to get rid of. Basically, I'll let Nagasawa-sensei decide if this will be just us taking a bath together or not.

"S-since it would be better and you're going to seal these memories, I-I think it might be nice to do something we would never even dream of doing. L-like, you can call me by my name and pretend I'm one of your women. T-then we could, um, pleasure each other. E-even I am a little curious about Lovers' fame."

Hehe, I knew it. Nagasawa-sensei either has a very vivid sexual imagination, or she's really frustrated. Even when I went to talk to her about a way to fix my grades, she immediately assumed I wanted to seduce her.

That's why I decided to let her say how far we'd take it. But I have to admit that I expected her to ask to just be touched a little or something. Still, I'll take what I can get.

"Alright, then let's do that. Just for now, you'll be mine, Taki."

Nagasawa-sensei's first name is Takizawa. I took some liberty and shortened it. I also called her name while looking into her eyes and putting our faces close together.

Nagasawa-sensei's body trembled a bit. And I'm willing to bet it wasn't because of the shower's water. Her nipples are already hard. I know I'm provoking her, but she probably has quite a vivid imagination.

"T-then, what should I do?"

"Well, when I enter the bath with one of my girls, we usually help each other wash. How about that? Do you want to start, or should I?"

"I-I'll do it. I may not be as experienced as your women, but I've learned at least this much from past relationships."

So Nagasawa-sensei has had boyfriends before. I'll be honest that I expected her to be the virgin teacher type, but this doesn't really lower her charm.

In any case, this shower room was so cramped that there was no way I could do something like sit and have Nagasawa-sensei wash me. I had to stay standing, but at least I got to feel her body's touch.

She asked me to turn around and then put some soap on her breasts. Well, when you think of a man and woman taking a bath together, using the breasts to wash is a classic.

"U-um, I've never done this before, so I won't be as good as you're used to."

"No worries. The good part about this isn't how well my back is washed, but how the breasts feel. And on that note, Taki doesn't lose."

Oh, I just noticed Nagasawa-sensei's teacher's nipples getting harder. So she's the type that's weak to compliments, huh.

And what I said wasn't a lie. As far as washing goes, Nagasawa-sensei doesn't have good technique, but if I'm just judging from the feel of her breasts, then it's pretty good.

A few minutes passed with Nagasawa-sensei doing nothing but rubbing her breasts on my back. Since it seems that's all she was going to do, I decided to move to the next step.

I turned around to face her. She was surprised at first, but she soon understood that I wanted her to wash the front as well. She began to rub her chest on mine.

"Yuuto's chest is so hard. You're more muscular than I expected. You really are a man."

"And Taki's breasts are really soft."

She washed my chest for a while, then she got on her knees. She was facing my crotch. I didn't think she'd go that far, but I really don't feel like stopping her.

Nagasawa-sensei sandwiched my dick between her breasts. My teacher is giving me a titjob. Between this and Reina, I think it's safe to say that I'm developing a taste for the taboo.

"Mmh~ it's so hard and hot. Those young girls are playing with this every day?"

"Jealous?"

"... A bit."

I wonder if she's being this honest because her memories will be sealed after. So is this Nagasawa-sensei's true face?

Nagasawa-sensei serviced me with her breasts for a while. She tried moving them in all sorts of ways and even licked my tip every now and then.

After a few minutes, I felt like cumming, so I pulled my dick from Nagasawa-sensei's breasts and aimed at her face.

I covered Nagasawa-sensei's face and breasts with my cum. I don't know, I just really liked the idea of cumming on my teacher's face and breasts. Regenerate made sure I had enough paint for the job.

"Nnn! It's so hot. And this smell and amount. Did you like it that much?"

"Yeah, I did. Taki felt so good that I want to claim you as my woman for real."

It was just a bit of lip service, something I knew wouldn't happen, but it made Nagasawa-sensei all embarrassed.

She got up from her knees and started washing her face and breasts. Her back was now turned to me.

There's no way I can resist that sexy butt. It's fine if we go on a bit longer.

"Now, it's my turn."

"An! Y-Yuuto's still hard."

"I'm Lovers' Candidate. One round is nowhere near enough."

"T-then, please wash me as well."

For all intents and purposes, I was just normally washing Nagasawa-sensei's back. That my dick happened to be rubbing against her butt is just a coincidence and definitely not my main aim.

I washed her back, and now I had to do the front as well. But I didn't ask her to turn around, instead, I reached around Nagasawa-sensei's body.

Of course, that meant I had to stick closer to her, meaning I got to feel more of her soft ass as I rubbed my dick against her.

"Mmh! Nn! Yuuto, how often do you do this?"

"Every now and then. You can tell?"

"Of course, I can. Aaan, my breasts."

Ever since I've moved to Lovers' Mansion, I often take a bath with the girls. It doesn't happen every day and it's not like I ask them to come with me, but when they show up, it's natural that something like this would happen. That's where my experience comes from.

I washed a good chunk of Nagasawa-sensei's front, but the main attraction is obviously the breasts and the vagina. I decided to start with the breasts.

They were really soft and nice to touch, their shape easily changed with just a little bit of strength, and the nipples were making their presence known. I couldn't decide which I liked more between her breasts and ass, but luckily the current position allowed me to enjoy both.

By the way, I could also see the nape of Nagasawa-sensei's neck from our current position. So naturally I kissed it.

"Nn! What are you doing?"

"Marking you. I can't just let such a good woman go."

"Mm, b-but, what if I notice it after my memories are sealed and look into it?"

"Yeah, Taki might remember. If you do and want to feel even better, come to me. At that moment, I'll mark you inside and out."

It's an unnecessary risk that I'm taking, but I just couldn't help it. Maybe because I know this is a one-time thing, I'm more excited than usual. Nagasawa-sensei also seemed to enjoy the lip service. Besides, how easy is it to notice a hickey on your nape?

I continued teasing Nagasawa-sensei until she reached an orgasm. From her moans, it seems this was the first time she came just from her breasts.

In that case, I'll give her a little more special service.

"A, Yuuto, there, aaan~"

I began playing with Nagasawa-sensei's pussy. I teased her clit with my palm while I pushed my fingers inside her.

I'm pretty sure she's never tasted several orgasms in a row, so I'll give it to her now. 3 or 4 in a row should do.

So I pulled all the stops. While I kept playing with her pussy, I used my other hand to tease her breast and continued to rub my dick on her ass.

Because she was sensitive, it didn't take her long to cum again. But I also started feeling like cumming, so I abandoned my original plan and instead focused on just making her cum while I also built myself up.

After a good 10 or so minutes of continuous orgasms, it was finally my time to cum along with her.

"Aaa, aaaaaa!"

"Mm! I'm cumming on your ass!"

I came on Nagasawa-sensei's ass. I'm definitely going to remember this every time I see her back in class now.

Nagasawa-sensei also came so hard that she was completely out of strength. So I had to hold her so she wouldn't fall.

It also worked as a good excuse to enjoy her naked body for a while more.

After a while, Nagasawa-sensei regained her strength. Still, she didn't let go of me. Or rather, she started holding on even stronger.

"Yuuto, you're not done yet, are you~?"

"... Maybe another time."

I put my hand on Nagasawa-sensei's head and quickly sealed her memory.

As much as I would have loved to keep going, I've already done more than I should. I must have been more pent up than I imagined.

By ending it now, it could still be just a fun one-off memory. That wouldn't be the case if we kept going.

Nagasawa-sensei's eyes went blank, and then she lost consciousness. I held her body, dried her with a towel, then I took her to her bedroom. When she wakes up, she'll probably think that she simply finished her bath and ended up sleeping. The mind has an incredible ability to trick itself.

As for unsealing her memories… let's leave that to her. I'll make it so that, if she starts questioning herself about her memories maybe being sealed, she'll get an explanation for it in a dream.

Nagasawa-sensei is smart, so she should be able to get the picture with just that. It's better for her if she doesn't remember. … As a little prank, I'll make it so that, if she remembers about the kiss mark on the nape of her neck, she'll dream about our little bathroom encounter.

Well, I don't expect her to remember it. The mark itself shouldn't stay for long, and it would be hard for her to see it by herself. In all likelihood, it'll stay sealed forever. Just a one-off thing.

After that, I left, since my job was already done. Still, I feel a little backed up. Maybe I should ask for someone to take a bath with me today. And maybe have someone cosplay a teacher after that.
