Plap~ plap~ plap~ plap~ PLAP!~

Her fingers digging into the wood of the desk she clung to, Seekvaira desperately held on as her asshole was plugged mercilessly.

Far from even thinking she'd be mildly affected by his cock in her pussy, now she was struggling to hold on to shreds of her sanity as his cock filled her anal cavity and made her orgasm with crazed intensity.

"Even this~!" She mewled, "You're too good~!" Her luscious tits swung wildly in the air, producing milk as they barely avoided chipping the desk.

"Fuck! I guess all your holes are slutty huh?" Akito slapped her ass lightly, "Look at how hard you're clenching around me!" He gritted his teeth, fingers curling around her plump ass cheeks.

"I-I can't help it, I-I want your cum, give me your cum~!" She begged, throwing her ass back and aiding the rippling of her ass as it slammed against his.

It had been forty hours since they started, and they were finally reaching the endpoint. There was a smidge left, though that by itself would still take a while. Truthfully, Seek knew the level of power she felt stored in that tattoo was far more than she needed to handle the likes of her rating game opponent, but that fact was far from her mind as she found herself hour by hour letting go of her prim and proper self and indulging in the pleasure.

(Akito POV)

"Like this then?" Seek asked.

I smirked wide, cock standing tall as I watched on from the bed at her current position.

She squatted down, standing on her tippy toes and in just some black thigh highs. Her legs were apart as her fluids dripped endlessly from her cunt and landed on the floor below her. Her tits hung down next to her knees. Her hands formed peace signs as she looked at the phone I pulled out and smiled, her face forming into the fucked silly face she had learned to do on command.

I snapped the photo, nodding in approval, and then watched as she stood up properly and came over to look at it. We sat at the edge of the bed and I gave her my phone so she could examine the photo. She did so, crossing her legs as she narrowed her eyes and studied every detail of the image. Meanwhile, her right arm outstretched and she took ahold of hard cock and began stroking it.

"It is good, but it's missing something. If I had to bargain, I'd say it's the erotic clothing, I will look into ordering some." She said, her attention panning from the phone to the larger monitor sat in the corner of the room. It was connected to her desktop and on it in full brightness displayed the paused screen of a hentai video. The girl in it was currently squatting down in the same position Seek had been in prior.

If you couldn't tell already, somewhere along the now sixty hours we had been in here, she had become a pervert. Or rather, it was like her analytical nature had taken on a new focus on lewdness. I had said before her favorite part of her research was the hands-on stuff, and that applied here as well. After I had passed out from energy depletion after our fifth or so round, she had gone on her computer and started searching for whatever interested her. When I woke up, I found myself something of a test dummy as she tried things on me and had me try things on her.

I made sure that before she reached the other side of that interest she knew that I wasn't allowing absolutely anything near my butt, nor was I engaging in any scat, vore, or other things I was just not into. Still, she found about a gazillion things, not including those, that she wrote down in her notebook.

"It'll have to wait until we're out of this room, I'm coming to envy that dimension you and Rias shared, perhaps I can fathom stopping time completely outside of a certain area, but the ability to buy anything and have it instantaneously in reach is something I cannot even being to replicate." She admitted, rotating her body until she was supporting herself with her forearm on my thigh and lying down perpendicular to me.

She continued stroking me and lowered her head to circle her tongue around my head the way she knew I liked. "Maybe I can find a way to bring you with me." I thought aloud, scrunching up her hair and holding it behind her head.

"That would be ideal, I'd like to get away from my responsibilities and be able to solely focus on my hobbies." She admitted with a regrettable sigh. "I suppose for now I should focus my research on improving my bloodline trait, I'm hoping your sacred gear will be able to help with that." That was another thing we had discussed. To use my gear to usurp her own power like I had done to Albion and bring it to a higher level, whether through my own training or through LP when I got back to the dimension.

My thoughts were cut off when her lips wrapped painfully tight around my head and followed her hands as they both worked down my girth. She was seriously getting good at that.

I took her glasses off her face and then leaned back to enjoy the sensations. I would say her change from her semi-prudence to this was dramatic, but truthfully it really wasn't. In the end, this had all become a part of her hobby. Her primary sin still was not lust, though it had definitely reached secondary with how frequent her cravings came. Her primary sin, I had learned, was in fact gluttony. It manifested almost entirely in the acquisition of knowledge. She wanted to know everything about what she saw as valuable, even stuff she really didn't need to know. It was why she now had my sizes committed to memory, and aspects of our debauchery down to a literal science.

Seek pulled her mouth off my cock after she had cleaned me entirely of the fluids we had accumulated from our last tryst. She sat back up, looking down at the tattoo above her womb. "I can feel that it's nearing full capacity." She noted. "Regrettable it may be, I think one more round is all it will take."

"Let's make it memorable then." I nodded, a slight sadness pouring through. This kind of reminded me of my time with Rias.

"Let's." Standing, Seek took my phone and placed it leaning on a water bottle atop the vanity. She turned on the camera and then adjusted it so it captured the entire bed. She then pressed play and walked her sexy ass over to me who waited while laying down.

She mounted me, legs opening and her feet planting on either side of my hips. She grabbed my dick, and swirled her hips around it, letting my tip brush against her ass until she slowly came to a stop when her pussy was directly above my cock. Her stoic expression melted into a glee-filled one as her ruby eyes rolled around her skull.

Just as she was about to start twerking her fat ass on my length though, the door to the room creaked open. Standing there, we watched as Ravel entered the sped-up space and as her gaze fell on us. Her eyes widened and her jaw went slack.

"Ravel? What is it? I don't like to be bothered when I'm engaged in my interest, you know this." Seek lightly frowned, utterly unaffected by being caught. Instead, she was still lightly rocking her hips as she faced the blonde shorter girl.

"L-Lady-…" Ravel was cut off, her red face going even redder as she made eye contact with me, and then the rod her King was taking up her greedy snatch.

"I-I'll go!" She exclaimed.

"You've already interrupted, you might as well tell me now." Seek said sternly, stifling her moan as my tip reached a certain place.

Ravel gulped, looking like she might pass out any second. "I-Issei, he uh- formed a contract."

Seek nodded, going back to thrusting herself off and on my member. "Ahnnn~ I see if that's all tell him I'll be out soon… Ahhh~! Right there~!"

With that, she dismissed her servant, her ruby eyes returning to me as she bit her lip and leaned down to hug me while still shaking her ass.

"Actually." She paused. "Since you're here, can you grab the phone over there and record for me?" She looked back over to her bishop who had been too in shock to leave in time.

"W-wha?! Y-you want me to r-record you… having-s-s-s-sex?!" She screeched.

"Yes, a still shot can't get every angle, it's better to have someone record instead." She said simply. "The phone is right beside us, it's already rolling so just hold it horizontally and move around a bit."

Ravel, turning into a blonde tomato closed the door and then mousely made her way over to the vanity next to the bed.

I knew she knew she could just politely refuse and then run away like she was initially going to do, but the way she looked at where we were connected told me why she stayed.

Seek resumed her prior actions, kissing along my neck as I went with the flow and began shifting my hips along with hers, meeting in a rhythm that optimized our rutting.

Slap~ slap~ slap~ slap~ slap~

Over and over my hips met her cushy ass and made it ripple. Our tongues met, and she held my face as she fought mine with hers. All her moans were drowned out as the kiss prolonged. Ravel off to the side did as she was told. She swiveled around the bed and tried her best to focus on what her horny brain thought were the best angles.

Soon, after Seek's cum was dripping down my balls, I slammed my dick into her cervix, breaking past her womb and unloading my cum right into her baby room.

Her walls wrapped tight around my shaft, forcing more cum to gush out of my tip. I could tell when the tattoo had reached her capacity as it wasn't disappearing around my tip, and instead flooded her womb and made her belly begin to swell. I pulled out, letting my cum droop down onto my dick and the bed. I was frightened when Seek started uncontrollably twitching atop me, and even more so by the deep feral growl that escaped her. I rolled her over, watching as her back arched on the bed and as her magic power burst out of her. It was thicker than usual, but it didn't seem to me like she was using the tattoo's stored power.

Her eyes opened to the size of saucers as she gritted her teeth. But, just as it started, it stopped. She sat up, eyes falling quickly to the tattoo and then to the rest of her body.

"That was.. unexpected." She said aloud, looking at me in confusion. "Did you know of this? Beyond the power I feel from the tattoo, I think my more permanent power just skyrocketed." She analyzed, clenching her fist.

"I didn't.." I admitted with genuine shock. "But, that is good to know."

"That isn't all, I feel for a lack of a better word, connected to you. I… feel things, I'm not sure-." Her words stopped at a halt as her eyes narrowed.

"Ravel, please hand me the phone and leave." She said aloud, stunning the girl who had been squirming.

"O-okay!" Ravel yipped, unsteadily handing over the phone before she scurried out of the room, leaving a trail as she did.

I was concerned about the sudden shift. Until I heard what she had to say.

"Akito, did you see a blue holographic screen when you first entered your dimension?"

Words couldn't express my surprise. "You can see it!" I stood up, knowing I wouldn't be able to see it but looking where she did nonetheless.

"I can… it reads that I've been 'whitelisted as a guest' and that a condition has been fulfilled on your end." As she said that, a familiar screen appeared in the corner of my eye.

[System report: Host has used the LP-bought skill: Power Bestowal to full capacity. As a result, excess LP has escaped the skill and formed a pathway between the recipient and the system. Excess LP has been randomly assigned across all recipient's stat points.]

My eyes went wide, a memory suddenly coming back to me as a probable explanation. This skill itself was very distinctly separated from the rest on the skill tree. If I had bothered to read the description I'd probably know why. If I were to guess, it would be related to that tidbit about 'excess LP'. I'm not sure how exactly, but there was LP stored in her tattoo as well.

Wait a second.

"Can you go there now?!" I exclaimed.

"No." She shot me down. "It's been very clear in conveying that I am a 'guest', my connection with this dimension is tied to your presence there."

My excitement dipped down and I sat back down on the bed. "Still, that opens up a lot of possibilities. I guess I can just give people access in a way."

"There is more still." She admitted, eyes furrowing as she reached down and took two handfuls of her massive tits. I watched in real-time as they began to inflate, and then as a familiar white fluid began trickling out.

I had not touched her at all, and yet…

"It also said a skill of a corresponding LP cost to that which could not be spent on my 'stats' was purchased to get rid of any excess LP entirely." She dropped another bomb.

Could she not have LP? Or maybe it was blocked completely until she got to the dimension as a part of the whole being a 'guest' thing?

"I'll be adding this to my research schedule." She stood, walking over to her notebook off to the side and scribbling it down.

After that, we talked while showering, discussing things we should try when we decided to do this again.

Thus, our 60 hours of debauchery came to an end.

A/N: I'll explain this a bit better. Power bestowal (The skill that gives the crotch tattoo) works by using Akito's own power and storing it, but it also uses the LP being generated to amplify it even further. When the tattoo reached full capacity the LP trying to find its way to the tattoo couldn't find its way in so it swarmed to her allowing for a bridge to be created between his LP and the temporary LP that she gained, thus granting her access to the dimension. The system that monitors the dimension and LP can react and 'update' in a way, hence a guest feature was added. Also, the LP she did get was auto-spent randomly across the stats she could afford to upgrade and then bought a cheap and available skill. She's not allowed to generate or store LP in her body (excluding the tattoo) outside of the dimension. I likely won't go into depth about this in the actual story, so just keep what I said here in mind.
