A New Kind Of Grind

I rolled over, pinning Akane to my bed and slipping my legs between hers, and relishing the sheer eagerness with which she gave herself to me, the way she burned with want.

The way she was desperate for me, and made it perfectly clear, in no uncertain terms, that my advances and affections were not an unwanted imposition.

It was reassuring.

So naturally, I had to open my mouth.

"Hey, this is probably the wrong time," I said, pulling back from Akane. "But what was the deal with you and Cecilia?"

"Huh?"

"I'm not getting possessive or anything, I'm legitimately just curious," I assured her.

"Oh. Well, I mean..." Akane trailed off. "She's a famous bunnygirl delver, and I'm half-bunnygirl." I was pretty certain that, as far as the System cared, Akane was just straight-up human, but... well, she wasn't calling herself 'half-bunnygirl' for no reason. "And... I'll admit, I already knew she was kind of a flirt, so... I wanted to see how far I could take that. Also, you saw her, right?"

"I stuck my hands down her shirt and my tongue down her throat," I said. "I assure you, you do not have to justify wanting to kiss her. I was just curious what prompted you to go through with it."

"Please make a good impression on her tomorrow," Akane pleaded. "If I can just so much as have a threesome with her, I can die happy."

"I'll see what I can do," I said seriously. "But right now, I'm afraid you're stuck with me."

"Oh no," Akane said flatly. "I only get to have sex with my hot alpha roommate with big tits who's mean when it's funny and nice at all other times. How ever will I survive?"

"You could start by untying your obi for me," I suggested.

"The knot's behind my back," Akane complained. "Besides, I want you to do it."

I sighed, pretending I was oh-so-put-upon for being compelled to unfasten the clothing of my bombshell fertility goddess roommate who is literally in my bed with the intent of having sex with me. I shifted my weight onto one hand, slipping the other under Akane and behind her back, and grabbed one end of her obi with it.

Did you know that [Magic Trick], a spell I use so frequently that I've been able to cast it without needing to say the incantation or make the gestures for the past four months, is capable of instantly untying knots? There are limiting factors, of course, but right now? I spent the barest mote of magic, and yanked my hand out and to the side, tossing the cloth belt that had secured Akane's yukata across my room, and letting the bounty of her curves spill out of it.

"You know," I said quietly, "it's been a while since I properly saw your tits. I think I missed them."

"Aw, they missed you too," Akane said, grinning at me. "In fact, I think they want a kiss."

I rolled my eyes a little, but nonetheless leaned in and down, pressing a gentle kiss to Akane's nipple. I brought my free hand in to cup and gently squeeze the attached titty, and sighed dreamily.

"I have to say," I began quietly, "I've had my hands on a lot of boobs, over the past half a year I've lived here, but of all those racks I've felt, I don't think any of them are so transcendentally divine as yours."

"And right now? They're aaaaaaall yours."

I simply leaned in and kissed her, on the lips once more, and pressed my body back against hers, my hands now roaming and exploring. After all, her body had far more than just tits that were worth laying hands on. There were those flaring broodmother's hips, those meatily thick thighs, that soft and plush belly... When I called her a fertility goddess, I was not exaggerating.

"Mmn," Akane moaned into the kiss, before pulling back enough to say something more coherent. "As hot as my knight in black armor is, I think we're at a point where you need a different kind of protection."

Two realizations struck me: one, I was still wearing a full suit of chainmail-lined clothing, and two, I had accidentally fashioned myself into some kind of godforsaken Futanari Kirito, and this filled me with shame.

Shame that I found myself unable to care about right now, because I was about to get laid.

I pushed myself upright, coming to kneel between Akane's legs, and, in a single exertion of will, I put all of my clothing back into my inventory, provoking a sharp gasp from Akane as she finally got to see me naked.

"Holy shit," Akane whispered, staring at my cock with rapturous desire writ large across her features. "I need that thing inside me, now."

"Are you sure it'll fit?" I asked.

I'd done some research before I settled on an ideal cock size, but all the same, I did have some reservations. The average beta's dick was six inches erect, while the average alpha and beta exemplar had dicks in the neighborhood of nine inches. Meanwhile, the cowgirls we had here, which I knew Akane frequently had sex with, had an average cock size of ten inches, with the biggest of the bunch being twelve inches. So, that's what I went with: twelve inches of meat swinging between my legs, because I was... whatever the counterpart of a size queen was. Overly-enthusiastic about having a huge dick.

"It will, and I'm going to love every second of it," Akane said firmly. "Roxy. Please."

I shrugged, and got to work. My left hand grabbed my cock, steadying and aiming it, and with my right hand, I began to finger Akane, getting her ready for me while carefully watching her reactions. Despite the fact that Akane was far closer to a cis woman from my reality, it still felt weird, after all this time fingerbanging cowgirl betas, to feel a vagina that didn't have a prostate embedded in its back walls. I'd been worried for a bit that this might remove a source of sensitivity for Akane...

...and, some unaccountable impression told me, I was right. Akane would enjoy penetrative sex, but she would not be able to actually cum unless I directly stimulated her clitoris. Not surprising, honestly- a lot of cis women back home were also like that, and... well, Akane was basically just one of those.

More interesting to me at the moment (yes, more interesting than a naked Akane I was about to fuck; I'm a nerd, sue me) was figuring out where that impression had come from. But... Well, it was obvious, wasn't it? I wasn't just a Wizard or an Alchemist. I was an Incubus, and it made perfect sense that I'd have a sixth sense for the sensual. And now that I knew what was going on, a solution presented itself to me.

"Hey," I began. "Do you mind if I do a bit of sex magic? Just, y'know. Make you a bit more sensitive, so you enjoy this more?"

"You don't have to, but if you want to anyways, go ahead," Akane said. "This is your reward for heroism, after all..."

"It'd be better for my ego if I could successfully make you cum," I said dryly.

"Fair enough," Akane said with a shrug.

And with that, I lined up my cock with her entrance- always a bit of a fumbling hassle, admittedly; it's not like I can see what I'm doing with my cock in the way- and slowly, carefully, pushed my way inside, relishing in the hot, tight squeeze of her pussy. At the same time, with my Incubus abilities, I was tweaking just how sensitive Akane was on the inside, increasing it by juuuuuust enough to let her have a g-spot orgasm, but without being so much that it became overwhelming or even painful.

"Oh wow," Akane breathed, panting a little already. "That is. Oh fuck, that's good. You... how did you... oh my god."

Don't ask about local religion, Roxy, just keep fucking her and leave it for later.

"I take it you're enjoying yourself?" I asked as I slid myself further in.

"Mmh- mmmmf- oh, fuck!"

As I crossed the six inches mark, I felt a bit of resistance at the tip of my dick, and Akane started breathing harder. This was as deep as a typical beta's dick would go in... but it was also about as deep as my dick would've gone in, before I made it twice as long with a potion.

"Keep going," Akane breathed.

I did so, and with a bit of force, I made it past the resistance, and was rewarded with a particularly tight ring of pussy that sloooowly slid down my cock as I continued to push inwards, before, finally, I bottomed out. I opened my eyes, which I'd closed while inserting myself without really thinking about it, just wallowing in the pleasure, and saw the outline of my cock poking through, just a bit, on Akane's stomach.

"Holy shit," I whispered.

"Yeah," Akane replied, nodding. "Keep- keep going."

I nodded back, and drew back my hips a little. Without even a small grunt of effort- god bless Incubus' ability to max out my base stats- I began to pump away at her, slow and steady, relishing the simple yet divine sensation of her pussy. Yet, while that stayed just as divine, I still found myself slowly ramping up my speed and intensity, because I just wanted more. And, well, it seemed that Akane wanted more too, as she started to moan, starting quietly and broken up with panting, but as things progressed, the moaning grew louder, longer, and steadier.

It wasn't long until I was pounding my hips into her some five times a second, while she all but screamed in ecstasy, shaking beneath me, her eyes closed as the pleasure overwhelmed her. I couldn't last forever, but... well, I didn't need to. I just needed to last longer than her.

And thankfully, I did. It was harder to tell when Akane was cumming than, say, one of the cowgirls, but thanks to my Incubus senses, I was able to bypass the fact that, a month or so ago, I'd been a virgin, and simply did not have enough practice to get good at sex the honest way. Akane came, moaning louder and squeezing tighter, and I let go and allowed myself to cum with her.

The swollen outline I made in her belly began to grow, as I pumped her full of, frankly, unreasonable amounts of cum. Unreasonable for a human, at least; enough to fill a coffee mug, but not much more. Oddly... I couldn't feel any leaking out, or even past the ring of tightness at the midpoint of my dick.

More odd, however, was a notification I got from Incubus: that I now had the option of offering Akane the Succubus slotless class. I wondered, briefly if this was a matter of Akane being the first real person I had sex with, or if this would happen with everyone I fucked.

"Oh fuck," Akane murmured, breathing heavily as she came down from her peak. "That was... holy shit..."

Hrm. You know, maybe I should hold off until after I've read up on this world's religion, and have an understanding of just how the fuck my Incubus class fits into everything.

I denied the notification; Akane would not be offered the Succubus class, and I would, instead, just collapse on top of her, and we'd enjoy some nice, relaxed after-sex cuddles.

"We've got to do this again," I whispered.

"Y-yeah," Akane agreed.

I sighed, wrapped my arms around her, and closed my eyes.
