After the talk with Rinne was over and she became my Card, it was decided we'd do Healing Lovers tonight. Rinne, Hisoka and Lizel went somewhere together.

I met up with Miyabi and the others for dinner, then I told them how things went. After dinner, everyone scattered about.

My Cards decided to spend the night here, since me and Rinne would. Everyone else decided to go back home, and Miyako and Rumi gave them rides.

Anyway, my Cards made sure Rinne and I wouldn't meet when I went to the bath. Speaking of, this place's bathing room is really amazing, like it'll probably give most 5-star hotels a run for their money. Or rather, this one is, at least, but I imagine the others are similar.

After that, I was told to just wait in the Healing Lovers room. Probably going to need a better name for the place if it's going to be used as often as it looks like it will. But I'll think about it later.

So I just waited there while everyone else went to go help Rinne prepare I guess.

They were taking a long time, so I explored the room a bit.

"This really is needlessly big."

There was a big bed right in the middle of the room. Most of the bedding was red, I guess because it's considered a sexual color. But even with the bed right there, there was still a lot of space left.

All of us that had been in the mansion today could probably comfortably stay in this single room. Maybe it'll feel a little empty with just 2 people.

Then again, considering the activities that are supposed to happen in this room, we're probably not even going to think about stuff like that.

There are a few balconies with a nice view of the outside. Putting that together with the windows and the TVs that can show footage from inside the mansion, we can probably keep an eye on the whole place from here. This was also probably done considering a lot of time would be spent in this room.

The bathroom is also really spacious, like I'm pretty sure 5 or more people can be here at once without any problems. There's even multiple sinks and toilets, I guess on the chance for high demand.

The bathing room wasn't much different, with showers and bathtubs all over, and a sunken bathtub in the middle. It was like the one I bathed in earlier, just bigger. I'm pretty sure I also see mats for those soap plays. Now I kinda feel like trying them one of these days, not tonight though.

So I went back to the main bedroom. … But Rinne's taking so long that I started thinking about what to do with this room. Like, what to add or change, since Lizel said it could be done.

I think about an hour passed with me thinking about stuff like that before Rinne finally showed up. I'm not going to complain, but I feel it is a bit much.

"W-wow, you're… huh?"

Rinne came dressed as expected for the occasion.

She was wearing a pink see-through dress negligee. Although it was see-through, the important bits were covered, only showing me her silhouette, which just made me want to rip it off of her. It doesn't look like she has any underwear on.

Her pink hair was also beautifully combed. She usually kept it in low twintails, but now it was let loose. One of the girls probably thought I liked it better that way. To be fair, considering how messy things get after a while, it's probably better for them as well.

Rinne's normal frown-like expression did lower the mood a bit, but not enough to kill it. And that wasn't the strangest part.

Rinne was holding a cup, which contained a red liquid.

"Here, I heard from Miyabi that you need blood to copy the Bloodline Magic, so I prepared beforehand."

"A-ah, thanks."

I almost felt like a vampire, but I suppose it was the best way to go about this. I really would be like a vampire if I bit into her neck or something.

In any case, I drank the blood. Now all that's left is to wait for Sein to analyze and copy the magic circuits.

[Analysis complete. Copying complete. Bloodline Magic Regenerate acquired.]

And with that, I got Rinne's Bloodline Magic.

Right after that, I felt a bit lightheaded. I knew this feeling, it was my mana getting used up.

[The simplest way to explain it is that Regenerate passively heals the body to the optimal condition. Yuuto felt lightheaded because of the sudden usage of high amounts of mana, but you should feel better soon and the consumption will go down once Yuuto achieves this optimal state.]

Huh, that's neat. So I guess I don't have to worry about stuff like getting sick anymore.

[It will also be very helpful in increasing your mana capacity and generally making you stronger, as well as other points. It is a very useful spell.]

I put the cup that had the blood in it on one of the tables. It should be fine to have it cleaned tomorrow.

After a few seconds, I no longer felt lightheaded. Rather, I felt great, like when you feel when you just recover from a sickness.

"Wow, this feels amazing."

"I can't really tell, since I've had it since I was born, but it seems this spell is really useful. Like, we can survive without food, water, air or sleep as long as we have mana to feed it. It also makes us harder to kill, and it's possible to even regrow limbs given enough time and mana."

It's like a blessing straight from god. Or maybe a curse, depending on the situation, I suppose.

In any case, that's enough side stuff. Time to get to the main point. But before that, I have to make sure Rinne isn't forcing herself.

"You know you don't have to do Healing Lovers, right?"

"You actually said it. The girls said you would say that. But I don't want you to worry about me, just do whatever you want. And besides, I'm probably the best person for you to try and learn how to do things now that you have Regenerate."

At that time, I didn't get what Rinne meant. But I would learn soon enough.

Since Rinne was fine with it, it was time to start Healing Lovers. I figured I'd ease her into it with a kiss.

So I kissed Rinne. It wasn't like the kiss to make the contract, so I tried getting our tongues involved. Since she seems to have little to no experience, I'll take the lead.

"Nnn, mmm."

"N, mm, chuu, nnn."

Despite everything, I think she's enjoying it. I wrapped my arms around her and pulled her close. I don't think she meant it, but she put her arms around my neck and deepened our kiss.

Since the negligee was thin, I could feel Rinne's nipples hardening under it. So she is getting more hot and bothered. It's good to know that she's also enjoying it.

After a minute or so, I ended the kiss. Rinne's expression wasn't her usual frown-like face, but rather a face that showed she was horny. It's good to know that she can show more faces than just the fake smile and a frown.

"I'm going to take off my clothes now."

I said. I admit I've also been kneading Rinne's ass for a bit now. Maybe that's contributing to her horniness. It's surely contributing to mine.

"S-should I take mine off as well? Or do you want to do it?"

"You can do it."

I don't have any particular fetish about undressing women and I think it's easier on Rinne if she does it herself. So I'll let her take care of it this time. That said, I don't dislike doing it either and I want to touch her some more, but I'll leave that for another time.

It wasn't long before I was naked and so was Rinne. I took a good look at her.

Her breasts aren't big, especially when compared to my other Cards, but they're not small either. They're right in the middle of the medium size. Her nipples also had a pretty and bright pink color, like her hair.

Speaking of hair, Rinne has pubic hair. From the looks of it, it seems she had quite a pink bush, but shaved it recently. Maybe just now?

"I-I tried figuring out what you might like beforehand."

"I see. I'm happy about that, but you didn't really have to do it. Just leave it however you prefer."

This might sound cliche, but I'm the type of guy who prefers it when girls are being themselves. There will always be points I like and dislike, but that's what makes it interesting. There's no point in changing someone to make them be exactly like I want them to be.

For example, when it comes to pubic hair, I prefer if there's some, but not too much. But the girl herself might have a different opinion, maybe she prefers shaving or maybe she won't mess with it. I enjoy finding that out more than knowing what I'll find there.

Regardless, I touched Rinne's private place and then kissed her again. While I tried getting our tongues involved in the kiss, I kept teasing just the outside of Rinne's pussy.

"Mmnh~ nn~"

"N, mm, nnh."

I'm not just teasing her. I'm also guiding her towards the bed. It wasn't long before I laid her down. And wow the bed is really comfortable, even just sleeping here must feel amazing… I almost got distracted for a second.

I kept our kissing going for a while more and I also kept teasing Rinne's tightly closed slit. Then, once the kiss was over, I sucked Rinne's breasts for a while. After licking both of them, I nibbled on one bright pink nipple as I pinched the other one.

"Mmhh!"

It seems Rinne is really enjoying herself. I'm almost unable to hold myself back, but there's still one more thing I want to do before getting serious.

After sucking on her breasts some more, I headed down while placing kisses on her body. Finally, I headed down until I was facing her crotch.

My sticky finger tells me she's already wet enough, and I didn't even put it in, but I want to tease her some more. So I started licking her.

"Nnnn!"

It's something strange to get hung up on, but I figured I wanted my dick to be the first thing that ever went inside Rinne, so I didn't push my tongue in. That meant I mostly played with her lips and clit.

Even though Rinne's lower lips were tightly shut, kissing that mouth of hers was quite fun. Especially with her trying her best to hold back her moans.

And, if all the juice flowing into my mouth is any indication, Rinne is enjoying it quite a lot. And it's a new taste as well. Maybe I ought to do a full lineup taste test one of these nights.

I kept licking Rinne for a good few minutes. I figured I'd go until she got an orgasm, and that didn't take long.

"A-aaaaannnn!"

Not only did she cum, she squirted. I drank a lot of it, but my face still got quite messed up.

Not complaining though. Once I finished drinking up, I went to go check on Rinne. To my surprise, she was covering her face.

"Are you fine? We can stop if you want."

"No, I'm fine."

She said as she turned around. Now she had her back towards me.

I know it wasn't her intention, but I have to say, nice ass.

"Just, do it, already."

She sounded a bit out of breath, but otherwise fine. So I guess it's okay to continue.

Still, I didn't expect her to want it from the back from the start. Or maybe she just doesn't want her face to be seen. But, since she's already in this position, I'll take advantage of it.

I got into position and put the tip of my dick at her entrance. I felt Rinne jump a bit, so I waited a second and then started pushing in.

"Mmmh!"

Rinne seemed to be struggling a bit. She was tight, the tightest I've ever felt. I have to admit I was worried about hurting her.

But I kept pushing in, and eventually I felt something. Thinking that was her hymen, I coated my dick in mana and then pushed it all the way inside at once.

"Aaaa!"

"It's all in now."

I made sure any pain she'd be feeling would be drowned out with my mana, but I still decided to wait a bit.

But not even 10 seconds passed before Rinne told me to go.

"I'm fine now, so move."

"Are you sure?"

"Did you already forget that I have a spell called Regenerate? So I'm fine already."

Fair point. Then I guess it's my time to shine.

I didn't want to go fast suddenly, since, regeneration or not, it is Rinne's first time. And it's not like I could anyway, since she was so tight.

So I slowly moved my hips. I was slowly getting faster with each thrust, but for now, we could really feel every bit of every movement. I felt my member scrape against every part of Rinne's insides.

"Mmmh! This, nnn! Aan!"

Maybe she didn't mean to show it, but I could hear the pleasure in Rinne's voice.

Rinne's walls pulsated in a rhythm. Right now, there's not much to them, but with time I imagine her body will instinctively learn how to move.

And her ass, it feels like a soft cushion when my hips slam against them. Like her breasts, they're not big, but they are well in the medium size.

Their softness showed she wasn't a girl who does a lot of exercising. I couldn't even feel her muscles and this soft feeling just made me want to ram my hips into her even harder.

"Rinne, I'm going to start going harder."

"I already said, nnn, don't worry about me aann. J-just do whatever makes you feel good."

"But I am. I like the feel of making girls feel good, hearing their moans, seeing their perverted faces. That gives me pleasure. So right now, your pleasure also makes me feel good."

"Nnnn!"

Oh, I think she just had a light orgasm when I slammed it all the way to her womb in one go.

Since it seems like I can go harder, that's what I'll do. Rinne seemed to enjoy me pulling out until the tip and then pushing it all the way back in as hard as I could. You'd think she might prefer it gentle since it's her first, but it seems Rinne likes it hard and fast.

It only took a few minutes before I picked up speed. Strangely, even after a while, I didn't feel my stamina going down at all, to the point where I kept going full speed for longer than I thought I would.

For whatever reason, Rinne refused to look my way, instead burying her face in the sheets. She might also be biting it, at the very least she's firmly holding them.

"Mmmh! Mmmm! Mmmmhhhh!"

Even so, her drowned out moans and her insides were quite sincere, so I used those to find how to make her feel best.

And once I found the spot where Rinne felt best, I kept attacking it. I didn't know I had so much stamina, but since I do I might as well use it.

"Mmmh! Nnnn! Nnnnmmmhh!"

So I kept attacking Rinne's weak spot for over 10 minutes, maybe even 15. I never slowed down at all. Rinne came a number of times, but she didn't seem too tired to continue, so I didn't stop.

Eventually, when I was starting to think it was strange that I hadn't felt like cumming yet, I felt my semen building up, so I knew I was about to cum.

"Ah! I'm going to cum!"

"Just, nn, do as you, mm, please~"

After a bit more thrusting, I came inside Rinne. I could have pulled out, but… oh well. Finishing inside feels better, and I'm pretty sure Rinne also came just from me filling her.

I came a lot more than I thought. When I pulled out, a lot came flowing out, like a white waterfall.

"... Wait…"

There was something wrong. My dick, it was still hard.

I mean, sure, I have a lot of sexual experience, and right now Rinne looks really erotic. But even so, I'm not a machine, I should have to rest a little after doing that much.

"Did you just notice…? Regenerate… also makes it, so you don't get tired. It really forces you to be in top condition at all times."

Even as she talked, Rinne's breathing returned to normal. That was Regenerate at work, bringing back her stamina.

Now I get it. I'll be in top condition so long as I have mana to feed Regenerate. That includes things like getting tired from exercise or sex. But Healing Lovers generates mana. So this is actually endless.

Huh, now I get what Rinne meant by her being the best person to teach me how to deal with Regenerate with Healing Lovers. If I'm not careful, she'll be the only one who can keep up with me.

I suppose I can just do it until I'm satisfied, rather than until my stamina can keep up. Yeah, that should be fine. I just have to draw the line somewhere.

With that thought, I pushed my dick inside Rinne to start round 2. I don't know how many rounds we'll have, but I know 1 isn't enough.

"That Bloodline Magic is actually more useful than I thought."

"Nn! You, do you actually think with your dick?"

No, not much, not all the time, I think it's normal.

I didn't know how to answer, so I just sped up my thrusts so Rinne would focus on moaning rather than asking questions. Right now, her mouth should be used for kissing or moaning, not for asking troublesome questions.

Regenerate really was amazing. Even though I had no rest in-between, I was able to go at my fastest speed without any problems and with no signs of slowing down.

I was still sensitive from before, so I came again in less than 5 minutes, but I didn't have to stop and just kept going for round 3. Oh yeah, this is going to be really useful.

This time, I decided to see if I could do something to keep going nonstop, but still last long between each shot.

It seems I can hold back a bit more if I concentrate enough. I was able to last longer than 10 minutes. I can probably work on this more, but that's a matter for another time. I'll ask Rinne about this spell's specifics later.

I pulled myself out of Rinne after I came for the third time. As it turns out, Regenerate also makes my body produce semen. So Rinne took three full powered shots back to back.

It felt incredible though. Knowing that I was able to have so much sex and cum so much without any rest and still being able to keep going made me feel like the world's most powerful man.

Are 3 rounds enough? … Probably not, so let's keep going. But let's change positions. Rinne's back is nice, but I want to try another position now. I want to mess with her breasts a bit now and I also want to see her face.

So I turned her around so that she'd face me.

"Ah!"

She quickly covered her face.

But I saw it. Just for a second, I saw a genuine smile of satisfaction on Rinne's face.

Of course, it's sexual satisfaction. But still, at that moment, my heart skipped a beat with how beautiful she was.

"What's wrong?"

"N-nothing. Just do whatever you want."

Is she embarrassed to show her face? Ooh, I like it, a girl that doesn't want to show her naughty face to anyone, but who will ultimately give into pleasure. I'm going to make her show it to me. I'm going to make her show me that face so much it'll be burned into my eyes.

I decided to play with her breasts a little. They weren't big, but they were soft and her skin was nice and smooth. I also had fun sucking the pink nipples.

But of course, that was just so Rinne was still horny. Still, it seems it won't be that easy to have her show me her face.

"Aaan!"

"Say, Rinne, I just thought of something. Since you've always had this Bloodline Magic, it means you've never felt satisfied, right?"

"I don't, nn, understand."

It's reasonable to assume Regenerate does for Rinne what it does for me. So, just as I can keep going forever, she's the same.

But it also means she probably never felt the pleasure of using all your stamina to satisfy yourself. Yeah, going forever is good, but there is a feeling of achievement in spending all you have in search for pleasure.

In that case, why not go all out? If I literally fuck her to her heart's content, I'm sure our relationship will deepen and she'll show me her naughty face of her own volition. Besides, I'm already planning to have sex until we can't anymore, so it's not even any extra trouble.

I made Rinne show me her face by pulling her arms away from it. I wanted to say it while looking into her eyes. Just as I thought, in her eyes, I could see she wanted more. She wanted to cum and to make me cum a lot more.

This may be her first time, but she's already a proper Lovers' Card.

"Say, let's both go crazy. Do it nonstop until we're satisfied."

"... Watever."

She might sound indifferent, but her eyes are telling a different story.

So I kissed her. I don't know how much of it she's meaning, but she's trying to use her tongue on mine.

Then, I grabbed her breasts. I made sure to tease them and her nipples plenty.

But I didn't put my dick inside her. That, she'd have to do herself.

"If you want it, you can put it in."

"... Mm."

Maybe she wanted it more than I thought. She grabbed my dick and started trying to put it in. She had some trouble, but eventually got it in the right position.

Since she managed that much, I pushed the rest in. Of course, slowly, so she could feel every bit of it. I felt her tongue tremble a bit, probably from trying to moan.

I began thrusting, but obviously I didn't stop anything else. Both the kissing and the groping only got more intense as I thrusted harder.

Just like I told Rinne, we went crazy. No matter how much she came or how much I came, we just kept going.

Of course, she was quickly filled to the brim with my cum. She was too tight for any to escape from our connection point, so I eventually had to pull out and switch holes. I didn't ask for her consent beforehand, but at the time I had completely forgotten and she seems to have enjoyed it, so let's leave it at that.

Needless to say, that also got filled eventually, but then I just switched back and we kept going. It really was nonstop.

Eventually, we got tired of that position and switched for a different one. We tried basically everything. Rinne was even more aggressive than expected when she was on top, but she clearly preferred me in control, and so did I.

We completely lost track of time, just kept going until we felt satisfied, completely lost in the pleasure.

Though a time when we were completely satisfied never came. What stopped us was something else.

"Yuuto, it's already nearly lunchtime… oh wow."

Lizel entered the room. I only noticed it when she said it. It was no longer night. The sun was in the sky.

I had Rinne on all fours and I was slamming my hips onto her ass. Even after Lizel called out to us, I couldn't stop before I shot another load inside Rinne.

"Mmmh!"

"Nnnn, mmmm!"

Only then did I somehow manage to pull myself out. That's when a continuous flow of semen from Rinne's vagina and ass fell into the bed, which was already very stained with all kinds of juices.

Because of Regenerate, I could still keep going. In fact, it took all my rationality to not tell Lizel to get naked and join us, but I imagined I would calm down after a while.

Or so I hoped anyway. Rinne also seemed to be having some trouble keeping herself.

"I imagined it would end up like this when I researched the Shimokadzumas' Bloodline Magic, but actually seeing it is surprising."

"Ah, sorry?"

"No, don't apologize. It's great that Yuuto now has it. I only see improvements."

Well then, maybe I ought to look forward to the next Healing Lovers. I now have the limitless stamina of a hentai protagonist.

But I'll have to remember the girls other than Rinne don't have this. I'll have to do some serious training to hold back. It seems its quite easy to get sex drunk with Regenerate.

"Oh yeah, Rinne, how are you feeling?"

"That was… not unpleasant. I could stand to do more… when Yuuto wants."

She said while looking away. Looks like she doesn't feel like being honest, even though she was holding and kissing me so passionately before. Oh well, time should deal with that, and it's also fine if she's only affectionate when we're alone. That's cute in its own way.

Even after spending the entire night with Rinne, I didn't feel tired in the slightest. I was a bit worried I had an eternal hard on, but it calmed down after some time. It wouldn't be nice to have constant blue balls, so that was a relief.

Apparently, from what Rinne told me, the ideal state that Regenerate brings me back to is influenced by my mind. During sex, I would be eternally hard, but once satisfied, it would calm me down. Very handy.

I guess, with this, I got a new Card and a new magic to play with.
