I never thought that my first time would be like this, spending the whole night fucking Merlin until sunrise... and keeping going at it without resting once. My room was hot and humid from our long, intense sex, and there was a musky smell permeated in it which only turned us on more.

"Ah... "

Looking at the moaning woman I was pinning down on the bed, thrusting my dick inside her and kept hitting her most sensible spot which I discovered at some point during the night, she wrapped her arms behind my neck and hugged me.

"Kay, kiss me... " She softly asked and I did as she said before wincing when I felt her vagina tighten the moment our lips touched.

As expected, she really loves kissing... then what about this?

"Merlin, stick your tongue out..." I said, making Merlin gaze at me in confusion as she kept moaning, but she did as I told her and stuck her tongue out in rather a cute manner.

"...Hike dis?"

"Yeah..."

Wasting no time, I kissed her again, this time with our tongues touching and entwining, and then I felt her inside squeeze my dick so hard I thought she was going to rip it off.

"Damn… Merlin, I'm going to…" I muttered, staring at Merlin as I could no longer hold myself back from cumming, having reached my limits. and Merlin nodded before she hugged me tighter and whispered in my ears.

"It's fine, let's do it together…" I couldn't help myself to let out a grin when I heard her words and, feeling myself getting invigorated, I decided to give it my all.

I then lifted my body, making Merlin blink as she was lifted off the bed since she hugged me before letting out a moan when I grabbed her soft and squishy ass, then proceeded to thrust my dick harder and faster inside her, eliciting her to moan louder as a result. But I quickly subdued them by kissing her once again, lowering the volume of her moans.

And I kept thrusting myself in Merlin who wrapped her legs around my waist not letting me go, with the only sounds in the room being the wet sound of our bodies slamming against each other and Merlin's moans subdued by our kiss, until I couldn't hold back anymore and cummed inside her.

"Hm~"

Hearing Merlin moan, I could tell she was cumming too, feeling her vagina tighten around my cock one last time, as if trying to squeeze every last drop of my cum inside her. And once it was over, I slowly pulled out my dick from Merlin's twitching vagina from where I saw a large amount of semen coming out of it.

"What a waste..." I heard Merlin mutter which made me chuckle a bit before I laid down on the bed, exhausted.

Glancing outside through the window, I saw that the sun had already risen high.

We really did it all night... I don't think I'll be able to enjoy normal sex now after losing my virginity in this manner... But still, she really is insatiable. I guess that's a succubus for you. Thank goodness that I bought [Sexual Calibration] the moment I saw her riding me and stripping.

Thanks to that perk, every little inconvenience that can make sex less fun no longer applies to me.

My partners will always be as clean as needed and smell just as I like, which is quite good in this era since hygiene isn't as good here than it is in modern times.

I also don't have a refractory period as it is removed, meaning I no longer need a break even after cumming, allowing me to keep going at it non-stop even if we do it for a long time like now.

But the most important part of this perk is that, for one, exhaustion will not be an issue for any participant in my sexual sessions until both of us are satisfied.

And honestly, if it wasn't for that, I don't think I would have lasted this long with Merlin. If anything, I'm sure that she would have sucked me dry. Well, fortunately for me, it didn't happen to me as this perk causes my stamina to not decrease and my body to keep producing sperm as long as I have sex which I think is what the description meant by how exhaustion would not be an issue.

And there is Merlin's belly which I could see a little bulging, mostly from the large amount of semen I kept pouring inside her the whole night, so this is why I believe the perk transformed my balls into high-speed perpetual sperm factories.

And I guess there is the fact that my sexual organs are more outstanding than what I used to have in my past life, my current dick and balls being the size that a harem eroge protagonist would have. Honestly, looking at my tool, I can't help but think that my past life dick wasn't really that big, even though it was a bit above the world average.

At first, when I saw my engine mature once I hit puberty, I was a bit worried since I heard that apparently, bigger doesn't mean better since a woman's vagina could only take up a few inches in, with only pros being able to take on larger dicks.

Well, it seems that I didn't have to worry since this perk also makes any unintentional or incidental damage that my sexual sessions might cause to simply not take place, essentially eliminating the pain and leaving only the pleasure behind.

In conclusion, this perk is making my body and every sexual intercourses I will have from now run on hentai logic, which is fitting since this world was originally an eroge in the first place.

"Hey, Kay…" I heard Merlin call me, snapping me out of my thoughts, making me look at the succubus who climbed onto my body, rubbing her bloated belly with a smile. "Don't you think I look like a pregnant woman like this?"

"Yeah, you look like it."

"Perhaps with that amount you poured inside, you might have already impregnated me by now."

"Sorry, but I don't think it will happen."

Another effect of the perk is that it can make it so that unwanted pregnancy and any complications of pregnancy never happen.

"How so?"

"I have… something akin to a blessing that allows me to be infertile at will… And I'd rather wait at least until the war ends before I give you a child."

"Is that so? Well, that's a bit of a shame. But if you can make yourself infertile, I imagine you can do the opposite, right?" I nodded at her question.

Well, I could buy [Fertility Calibration] which would give me total control over the chances of pregnancy in any of my sexual encounters. I could impregnate any woman in a single shot if I wished so, even overriding any fertility control they have.

"Then, I guess I'll have to be patient…" Merlin said as she snuggled by my side with a wide smile on her face and started to hum happily, which surprised me a bit.

I don't know why but her smile right now...seems more genuine than the ones she had before. If anything, it makes her more beautiful...

Closing my eyes, I cuddled Merlin close to me before I noticed something missing in our surroundings.

"Hey, can I ask something?"

"Yes, what is it?"

"Did you really put a Bounded Field like you said? Because I can't sense it at all."

"Ah..."

Then, a silence seeped into the room, the only sounds that could be heard were the cries of the birds coming from outside.

"I know I placed it but...I think because you were so rough with my frail body, I may have dispelled it while we were doing it." Merlin finally said as she gave me a coy smile while I felt the urge to facepalm.

"So, it's my fault now?"

Damn it... I was so into it I didn't notice she didn't put a Bounded Field. I hope nobody heard us... No, I'm pretty sure they did. Merlin did squeal a lot that night, even if I kept shutting her up by kissing her.

This is going to be awkward...

Yeah, as expected, they know...

When I went inside the dining room with Merlin by my side, I saw my mother looking at us beaming with joy as she quickly got up from her seat when our eyes met and then ran towards us before grabbing my and Merlin's hand.

"So, when is the wedding?"

"We... haven't decided anything yet, so can you keep it a secret for now? We planned to make it a surprise."

"Oh, I see. Don't worry, your mother is good at keeping her lips shut. But still, I hope it happens soon. I'm already excited to see my grandchildren's faces." She said as she went back to her seat, a beaming smile on her face while I quickly glanced at Merlin who looked as happy as her.

"Hey, Merlin. Do you know a spell that would erase her memories of last night?"

"Yes, but why?"

I can't trust her not to talk about what happened last night, gossiping with the other farmers and I fear what would happen if she starts talking about a marriage between Merlin and me on the spur of the moment.

"Just can you do it for me? I'll do anything you want later."

"Alright, I'll do it. But you better explain what happened yesterday, and what you were fighting against in your dream." I gave a quick nod to Merlin who then snapped her fingers, and I saw my mother stop in her tracks for a second before she tilted her head in confusion.

"Hm? Why was I so happy? Oh yes, Kay, I'm really glad you are alright. You made all of us worry yesterday."

"Ah, yes... I'm really sorry about that." And for erasing your memories. "But it's fine now, I'm in perfect form today." If only a bit tired because of Merlin's insane stamina.

"That's great. Just wait here, I'll make you some breakfast."

When I saw her head to the kitchen, happily humming, I let out a sigh.

Alright, crisis averted for now...

I thought before I saw the front door being open with Ector behind it. Then, our eyes met and I was a bit confused when he looked at me a little... resigned? He then approached me and patted my shoulder.

"Kay... if you truly think that Lady Merlin is the one for you then... I give you my blessings but, please, don't destroy the country with her."

Did you finally become senile, old man?

I couldn't help but to think as I saw Ector walking away in the direction of the kitchen, before I glanced at Merlin who shrugged her shoulders and snapped her fingers at the old man. Then, I blinked when I heard a loud scream coming from the bedrooms.

"Big brother, where did you go?!"

Glancing down the hallway leading to the bedrooms, I saw Artoria running out and stopped in her tracks the moment she saw me, her expression quickly changing from concern to relief.

"Brother Kay, you're alright!" She shouted as she ran to me and hugged me tight which made me chuckle a bit.

"Sorry, it looks like I worried you."

"It's fine. As long as you're alright..." Artoria started to say before she stopped as she stared at my body for a moment and sniffed it, making me blink in surprise. "Brother, you smell... funny..."

Shit...

"Ah, it's because I sweated a lot in my sleep. I must stink so can you let go of me? I need to go to the river to wash myself." I said as I tried to make Artoria let go of me, but she didn't release her hold and shook her head.

"I'll come with you. After what happened yesterday, I want to be sure you are completely safe and healed from whatever you had."

"You don't need to worry about that, I'm fine. And what about my privacy? You don't want to see your brother naked, right?"

"I've heard it's normal for siblings to see each other naked, so I'm perfectly fine with this."

"From whom did you hear that?" I couldn't help but ask aloud, and Artoria turned to Merlin who gave me a wide smile when I looked at her.

"Just let her do what she wants. You should know by now she won't take no for an answer."

"You know... I thought you had changed a bit, but it looks like you haven't at all. I guess I'll have to punish you harder next time."

"Try it if you can." Merlin said as she patted the area below her stomach with a smirk, while Artoria only tilted her head in confusion at our conversation.

Seriously, I thought I had better taste than that…

As I cleaned myself in the river, I explained to Merlin and Artoria, the latter whose face was as red as a tomato, a little summary of what happened yesterday.

"So, you were fighting against those knights in your mindscape so you could gain a new ability, and because they were stronger than you thought, it took you an entire day to beat them all." I nodded at Merlin's words before a display appeared in my vision.

Kay

Your tier - T8

After managing to subdue the seven sword gods yesterday, I managed to raise up my tier, much to my happiness. But it wasn't the only thing I managed to do.

Congratulation, you have managed to fill the gauge of [Exit Stage Left].

Would you like to jump to your next world?

Warning: Time between worlds flow differently.

One week spent in the world you currently is equivalent to one day in other worlds you already visited.

You may increase the interval the more worlds you visit.

I thought I wouldn't be able to fill the gauge until I helped Artoria become a king, but it seems like everything I've done in the past nine years was more than enough. But if there is a little downside, it's that the next world is guaranteed to have a danger level ranged between 6 and 8. I could have bypass that if I bought the perk [Pursued by a Bear] but I don't have enough credits for that. I'm not too fond of taking a loan either... Well, I can only hope that gacha is on my side...

As I left the river and dried myself with a towel, I clenched my fist and started to pray to whatever deities I could think of.

Please, grant me your blessings... Alright, please show me the next world!

Granblue Fantasy

Danger Rating - 6

Oh... Seriously? I can't believe it, is it fate or a coincidence?

As I pondered about the chance of getting the world where I bought the template of a character he was originally from, I saw a new display appear in my vision, which made me frown.

I have to say, this mission is tempting me a lot, especially the rewards as they were all weapons that were said to be able to destroy the Granblue verse seven times. I really want to get them...

"Brother, are you alright?" I heard Artoria say, making me look at her to see her and Merlin looking at me with concern in their eyes.

"It's nothing, it's just... I feel like going on a journey right now." I said as a portal appeared by my side, surprising both Artoria and Merlin as they looked at me with wide eyes.

"Wait a minute! Where do you think you're going?!"

Hearing Merlin shout for the first time, I blinked in surprise before I gave her a smile, as I grabbed my clothes and turned my back on them, preparing myself to enter the portal.

"I'll be going to where my powers originate from, to one of the worlds that exist beyond the Root."
