We're going no holds barred here. For y'all lazy-ass readers who wanna skip to the smut, use the find function for the word "pursing".

We both made our way upstairs together with Komachi still clinging to my arm, but as we reached the door she excused herself.

"What's wrong?"

"Y-you go ahead, I-I just need to do… something." She let go of my arm and without looking back rushed off to her room.

I didn't get the chance to ask her so I decided to wait it out in my own room, sitting on the edge of my bed. The only noise that filled the place was the loud, rapid beating of my heart and the impatient tapping of my foot on the tatami floor. My eyes roamed around the four corners of my room, from my study desk to my closet, to my book shelf full of various novels and manga…

There was a secret spot there, you see. At first glance it looked like a row of normal titles, but if you moved closer you could see that I had moved the "safer" titles outward. In between them were the more dubious pieces that showcased some rather questionable illustrations on how one should mingle with their respective little sisters. Thankfully, Komachi was neither tall enough to reach that high up the shelves nor has she ever tried looking there whenever she did a surprise clean-up of my room.

…wait, why am I even telling you guys this in the first place? Anyway, don't tell Komachi…

A few minutes had passed and she still hasn't come, I was already at wit's end thinking she might've thought things through and locked herself in her room until our parents came home. Just as I had stood up I was rattled back to my seat by three soft knocks followed by her voice.

"Come in." I said. The doorknob twisted unlock and swung open slowly, revealing my little sister who for the first time looked particularly embarrassed to enter my room.

Usually she'd come barging in without any care for my privacy nor personal space with that goofy, energetic smile on her face as always.

But now she had a shy, reserved expression that made me believe this was all but a dream, however the constant throbbing inside my trousers told me quite otherwise.

As she shut the door behind her she leaned back on it and just stood there with her hands behind her, never looking me in the eyes. The air was getting heavy so I decided to speak up.

"S-so, what happened? You took some time getting here…" I wasn't exactly sure what to talk about as even I was on the verge of a nervous breakdown.

"N-nothing much, Komachi just looked up some… things."

"Things? What things?"

"Y-y'know, about s-stuff that w-w-we're p-probably about to do…" Her voice went softer as she spoke.

Oh… Oh.

I had never seen her this embarrassed about something before. Komachi looked like she was about to cry any second, and while normally I would be there to help her out on whatever it was that troubled her right now I was at a complete loss.

"So then… that means you're fine with this, right? As in, you're not feeling forced or anything?"

"I-I guess…"

It was getting harder to talk with the distance between us so I urged her to stay beside me. Komachi obliged and plopped down laying on her side, nibbling on one thumb while facing me as I sat by the bedside. Also, I felt it was noteworthy that at this angle I could get a good view of her cleavage again.

"Listen, before everything else I need you to give me a solid yes or no. It just won't do if you feel half-hearted about this. I'm well-aware of what kind of trouble I got ourselves into, and I want to know if you do too and if you're willing to continue what we've started. I don't want to drag you down any deeper in this, so I wanna hear your feelings."

"It's not like Komachi doesn't want to…"

"Then what's wrong?" I gently stroked her head, tucking away some of her hair behind her ear so I could see her face which was stricken with uneasiness.

"After what happened earlier, I don't know why but I feel differently about everything… and I'm also scared. W-what if tomorrow morning when I wake up, I regret this? O-or what if Onii-chan was the one who changes his mind the next day…"

To be honest, I couldn't blame her as part of me also felt that way. However, I had surmised that this would only be a one-time thing and will be a secret the two of us would carry to our graves. I never gave a long-term relationship much thought since first of all, this wasn't exactly an accepted thing according to society's moral standards. Secondly, I didn't expect Komachi to find me or this affair between us worthy of keeping. She was a cute girl who could probably find other more suitable men, those who could give her a brighter future and a happier life.

Unlike me, who had nothing going on in his life and was the lowest of the low, making advances on his own flesh and blood. To think she had been worrying over something like me throwing her aside after having a go at her while I busied myself with nothing but how we would never unearth this night ever again... I only felt more that I didn't deserve her affection.

Yet part of me wanted to be selfish, part of me wanted to pursue this dark, thorny path that would probably lead to nothing good. Contrary to my normally logical decisions I still chose to take this route because I knew at the end of the road I would be with her, even if it meant us against the world.

"I don't know for sure if you'll wake up regretting it but… I want to let you know that I'll never feel that way."

"R-really?" Komachi looked up to me with her round eyes. I must've scored a few points with that line.

Seriously speaking I had no clue as to how much of our feelings were real since we were probably swayed by hormones during the heat of the moment, but I do know that this, to a certain extent, was completely genuine.

"Really. In the future, I'll visit this memory over and over and I'm sure it'll never fail to make me feel happy."

"Y-you're not going to do that to yourself while thinking about it, are you? And won't you have a wife or a girlfriend then?"

"Ah. I don't know about that." I chuckled at her question. "I'm not exactly quality husband-material, and after what happened I really can't get married anymore."

"H-hey, that's my line!" Komachi sat up and lightly punched me before crossing her arms. "I'm supposed to be the one who tells you to 'take responsibility!'"

"Well, I'll more than gladly do so. That is, if something will happen." Her face went red all the way up to her ears as she looked away. If talking to girls was as easy as talking to your little sister, then maybe it wouldn't be so hard to get a girlfriend.

I'd still most likely get rejected though. Ah, if only dating your sister wasn't forbidden in real life…

"I-if that's what you want…" She responded, facing away from me. But that won't do.

"I still want to hear either a yes or no; do you really want to do this?"

She finally looked back to me, her eyes searching for what could be the answer. If I had known, I would've spent a moment to write a large "yes" on my forehead with a marker.

"Yes. I… I-I want to do it."

And there you had it, she finally gave her consent. Not that it made this any less unacceptable though.

But I at least had the peace of mind that she wasn't feeling forced or anything. As much as I wanted to feed my cravings, I did truly love my little sister and I wouldn't want to harm her in any way.

Anyway, enough of that. There were more pressing matters at hand that needed to be addressed.

"That's great. So then, do you wanna… try kissing again?"

"S-sure…"

We fumbled with how to start off, the awkwardness of intentionally doing it for the first time being quite the obstacle for us. Being the guy and the older person, I decided to take the lead by sitting to face her properly and holding Komachi by the shoulders once more.

"Then I-I'm going for it." I warned her in advance. She nodded and closed her eyes, pursing her lips for me.

I gently moved towards her and as soon as we touched she took a sharp intake of air. I pressed myself harder onto her as we deepened into our kiss, goosebumps running across my skin. Her lips were lusciously soft and sweet, like the taste of fruity cotton candy being sold during summer festival. I could almost hear the fireworks booming loudly overhead.

Komachi began to fight back, pushing her face towards me as we remained connected to each other. Her intoxicating scent filled my nostrils, driving me to yearn for her even more. My hands slid from her shoulders down to her arms and finally rested on the curves of her hips, seizing her in place as I continued to indulged in her flavor.

We separated once we were reminded the need for air, gasping as we broke apart. I was face-to-face with Komachi's flushed cheeks and heavy breathing as we rested on each other's forehead, locking our eyes together with a distant gaze while her arms were wrapped around my neck.

"T-that *pant* was amazing… M-more than *wheeze* the first time." I spoke in-between catching my breath, still riding high from our activity.

"Nnn, d-don't play with my sides too much…" She complained as my thumbs felt around her small waist.

"Why, does it tickle?" I used every other finger to lightly strum her sides. Komachi drew one hand back to cover her mouth but a cute little moan had already escaped.

"No, b-but it's making me feel funny…"

"Oh, does it now…"

Komachi bit her lip as I attacked her weak spots incessantly, her body twisting and contorting in response before hugging onto me tightly.

"C-could you go… a little higher?" She whispered, her hot breath wafting on my ear before pulling away from me. I glided my hands up, putting a little force so that I could slightly feel her ribs through the thin fabric of her shirt. I stopped as I overlapped the strap of her bra located just below her armpit.

I gulped. I was two layers of clothing away from understanding why the protagonists of my ecchi novels had those smiles on their slapped faces whenever they got to cop a feel. After this, there was no turning back, not that I initially had any plans to do so.

"C-can I…" I didn't finish my question, but she seemed to know what I wanted and nodded quietly. With her approval, I moved my hands to her front and placed them over her chest.

I could feel their mass moving around underneath the palms of my hand as I lightly fondled them. How should I explain it… I could feel even from behind the cups of her bra that they were soft, much, much more than I had ever imagined. It was strange how it was almost just like kneading dough, but there was something else to it that made you wanna do it again and again, no matter what.

Things were going well, but I wanted more. Call me greedy, but when I finally had the opportunity to explore the opposite sex there was no telling when the next chance would be. I also wanted her to feel good since I didn't want to be the only one enjoying myself here.

As I told her to raise her arms I grabbed onto the hem of her shirt, pulling it up and all the way over her head so I could toss it aside. Before me now sat Komachi with her upper body clad with nothing but a plain black bra. I ogled the increased amount of exposed skin, making sure to give a silent prayer to the gods before I resumed to caress her breasts.

"Aahn… O-Onii-chan, that feels good…" Komachi commented, her voice sounding quite erotic. She gripped onto the bed covers and arched her back, pushing her body onto my hands.

But it still wasn't enough.

"I want to touch them directly." I demanded. She appeared to be hesitant at first but turned around and pointed at her back.

"Okay, take it off for me."

I fumbled on the strap behind her that held the brassiere fast in place. I figured the hooks only had to be detached from each other but my hands were badly shaking in uncontainable excitement that I took a while to do such a simple task.

When I had finally succeeded to unclasp them she turned back to face me with her arms covering her chest, still holding her bra in place. Slowly she lowered them and revealed to me her lovely bosom whose protruding pink nipples were surrounded by the lighter skin of her tan lines.

Komachi was quiet, anxiously waiting on what I was about to. I reached out for one of her nipples and gently pinched it between my thumb and index fingers, feeling its hardness.

"Aah! Mmm-!"

She let out a moan much louder than her previous ones, her body tensing up before shuddering. I placed my hand on her other breast, feeling the erect nub poking at my palm as I pressed down. The size of her soft mounds fit perfectly on my hands, and their bounciness rebounded with such youth. Playing with boobs without a shirt or bra was indeed way better, as I expected.

"Is there anything you want me to do Komachi?" I asked as I had been fondling her chest for some time, and while she seemed satisfied enough with my actions I wanted to know if there were other things she had in mind.

"Well… C-c-could you suck on them?" With a face that red, I couldn't tell if she was feeling shy with her request. But hey, what were tits for anyway?

"Sure, then if you'll excuse me…" I brought my face closer to one and flicked her nipple with my tongue.

"Hyaa-!" She flinched, feeling the slimy appendage grazing against her. I decided to tease her a little further, alternating between them until she yanked on my hair to have me start on what she wanted.

"Itadakimasu," I said before placing one inside my mouth. I lightly sucked at first and gradually increased in force, checking how much was needed to provide her the most pleasure. Once I found the right amount I maintained a slow pace while my tongue traced circles around her areola.

My taste buds picked up the slightly salty taste of sweat from her skin as I savored her. She began to pull at my hair, but the pain it dealt only served to heighten my libido and turned my suckling into a voracious session. Komachi's sultry voice reverberated in my ears as I fulfilled her wish, awakening her into a world full of carnal desires.

As I continued to assault her she fell back down on the bed with me on top. Her body squirmed wildly from being pleased, her limbs unsure on where to hold their footing as she sunk deeper into the abyss of pleasure. Her breathing grew ragged with each passing moment up until she could no longer contain herself.

"O-Onii-chaaaan!" Komachi screamed at the top of her lungs with her back arching once more. She pressed her thighs tightly together as if to stop the overflowing satisfaction that erupted from between her legs. Every part of her trembled and remained strained before her body fell limply on the mattress, the expression in her hazy eyes exhausted yet visibly satisfied.

I only felt the toll on my body once the adrenaline from my lust-filled attack had waned, my clothes drenched in sweat and the cold negligible against the warmth that emanated from our bodies. Lying beside her we both caught our breaths, my stamina may have been depleted but a highly neglected part of me was still raring to go.

Draping an arm over Komachi I pulled her closer to me, not wanting to let the distance between us grow even by just a centimeter. I wiped away the beads of sweat from her forehead and watched her chest rise and sink.

I realized I had never felt this strongly for any other girl in my life for as long as I could remember. Sure, Komachi has always had a special place in my heart, that went without saying. But now, it seemed that she had occupied not just the one spot reserved for her, but every nook and cranny of it that I had left vacant. Just thinking of being separated with her now was enough to scare me half to death.

I wanted to spend the rest of my life with her, no matter the cost. I wish time could just stand still for us, so I could stay beside her like this forever in peace…

"Onii-chan, that felt great." She spoke still catching her breath, breaking my train of thought. I gazed at her cute face and smiled, happy to hear she had a good time.

"Anything for my little sister."

"You are such a sis-con." She giggled then nuzzled my chest. "Anyway, do you want me to do something about… that?"

Komachi then pointed down where a certain friend of mine bulged from my shorts and happened to be poking her thigh.

"Hehe sure, i-if you could, I'd be more than happy."

"Okay, since you made Komachi feel good, she's going to return you the favor."

She instructed me to stand up first and take of my top. While I did that and still had my shirt over my head, I felt her hands grab my shorts and pull them down along with my underwear without warning.

"W-whoa!" I felt my dick swinging back into its erected position after it was caught along with my boxers' descent. Hurriedly removing my shirt I found Komachi staring at it with eyes wide in surprise.

"T-this looks a bit bigger than I remember…" She remarked, showing me the size she recalled with the gap between her hands.

"That's because it's hard right now, when we bathed together it didn't get this way because…"

Because I wasn't sexually attracted to you yet back then, was what I wanted to say. Well, she was too young then so there's no way I could ever get an erection, unlike now that she's ripened a bit...

The way she was eyeing my prize, it was way too intense. If I was a little more sensitive, I might've ended up cumming on her face right then and there. I originally felt shy to show it to her, but now that it was out in full display I couldn't help but want to flaunt it even more in front of her.

"A-and this is… going inside me? All of it?" She gulped, gauging herself against my length.

"Well, that's if you wanna do that… S-sex, I mean."

"I-I'm a little scared, b-but I do want to try it…" Komachi confessed, although I could see the worry streaked across her facial features.

"We don't have to do it right away. We can try something else first, then you can decide if you do want to do it or not." But if you had to ask me, I was seriously hoping she'd give it a shot.

"Okay… I guess that's fine too."

I was this close to pumping my fists in the air in joy. Well, it's not like she already agreed to it, but the way she sounded felt like she was more likely to consider going all the way with me.

But before that, she wanted to help me out first like how I did with her so she told me to sit back on the bedside and let her do all the work. I followed her command, my heart pumping like crazy when she knelt before me with her face close to my boner.

Her fingers gingerly wrapped themselves around me, feeling myself getting harder from the sensation of her touch alone. Gently she began to move her hand up and down, her inexperience was evident on how sloppily she handled me. Still it felt crazy good, it was way more pleasing than doing it myself even with the best fap material on hand, and having someone to do it for you was in itself heartwarming.

"Does it feel good?"

"Y-yeah… But could you pick up the speed a little?"

Komachi gripped my cock a little tighter and picked up her speed, effectively doubling the amount of friction I was receiving. Pleasure was beginning to build up inside of me, and despite her being a novice at this I knew I wouldn't last long with how well she was currently doing. I pulled my head back in delight and enjoyed letting my little sister work her wonders, closing my eyes to focus my attention solely on my dick.

"U-uwaa! T-t-there's something coming out of it! A-are you cumming already?"

With that Komachi pulled her hand away and pointed at the precum that was leaking out of the swollen tip. While having my fapping session interrupted so abruptly like that was painful, her innocent reaction touched my heart.

"Relax, it's just a sign that it feels good." I calmed her down, I guess she really was new to all this. "You're doing a really nice job."

Of course, it's not like I had instances of someone else doing it to me for comparison purposes, but I couldn't tell her that. She probably knew that fact anyway.

She then resumed to her task, drawing me ever closer to my limit with each stroke. My precum had dribbled so much that her hand was making wet, sticky sounds.

Looking over at her she was still half-naked, her boobs bouncing along with the pace of her hand. I badly wanted to touch them so but sadly they were out of reach, and sucking them again was even more impossible.

"Umm, Onii-chan…" Komachi once more paused her movement, leaving a lot to be desired. "Listen, I was t-thinking… Well, I-I never t-tried giving a… b-b-blowjob before, s-so I'm not c-confident in my skill, okay? Just tell me i-if it hurts or if it doesn't f-feel good…"

She took a deep breath and prepared herself, still looking overwhelmed at my length as she had never seen a real one before this. She kissed the tip first, smearing some of it on her lips which she licked off clean. Holy crap, that was sexy as hell.

"Salty…"

Holding it firmly in her hands she opened wide and carefully put me inside her, making sure to avoid her most of her teeth. I could feel her fang lightly grazing the side of my penis as I entered her mouth. She could only fit around half at most but it was more than enough to drive me crazy.

As her head bobbed up and down on me her tongue rubbed and licked me at all sides, leaving no spot left untouched as her saliva drooled from the corners of her lips. With her eyes looking up to me it was like watching a POV-type little sister AV, but with the added bonus of sensation. The best virtual reality eroge was nothing compared to something like this, I felt sad for those out there who would probably never experience such bliss that I once didn't know existed in this world.

As Komachi generously serviced me with mindblowing oral sex I was getting closer to cumming. I didn't want to finish soon and getting blown wasn't making it any easier to think, but I came up with an idea that would give me even just a minute to breathe.

"Hey, lie on top of me too. I-I wanna do the same to you." I ordered, wanting to share the pleasure with her so it could be a win-win situation. She pulled me out of her mouth and undressed her shorts and panties before getting on the bed, giving me momentary relief. As I lied on my back she got on all fours above me, her bare pussy now right before my face. She was moist and it exuded a nice, alluring musk that was highly addictive.

"It's a little messy though… f-from earlier." She excused, but it didn't matter since it'd be even messier once I was done.

She once again took me inside, pairing it with gentle strokes from her hand. As for me, I took a few seconds to appreciate the view from the gap between our bodies before I buried my face between her legs and gave her pussy a torrid kiss, lapping up any of her juices that leaked out.

I glided my tongue across her slit repeatedly before shifting onto her clit, imitating whatever I've learned from gigabytes of streamed porn. I flicked and squeezed it between my fingers, causing her to let out muffled, satisfied moans which sent vibrations running through my dick. She on the other hand was doing a splendid job on me, so much that I couldn't hold it in any longer.

"I-I'm about to cum." She was doing a splendid job on me that I couldn't hold it in any longer. I warned her so she withdrew my cock for the meantime but continued with a slow-paced handjob. "S-so, do you wanna try having sex?"

"O-okay."

As she got off me I remembered something of importance.

"Right, I don't have any condoms with me. I never did really have any use for it until now." I admitted, but it didn't hurt as much since I was about to lose my v-card tonight.

"But what if I get p-pregnant?"

"Umm… we'll cross the bridge when we get there or something."

"That's no good! W-what if Komachi does end up with a baby?" She punched my arm. Her face also told me she wasn't even the least happy with my response.

"I'm sorry, I really suck at reassuring. But I'll definitely take responsibility, that much at least I can promise you. Okay?" I said with a smile, she just sighed at me and shrugged her shoulders.

"Fine…"

I ordered her to lie down and spread her legs, nervousness evident in her facial expression. I felt the same but I thought best to hide it from her. If ever I showed any weakness at such an important time it may scare her.

"D-don't stare at it too much, geez…" Komachi covered her face with her hands.

"Sorry, I just wanted to get a better look."

I played her clit for a little bit again to ease up some of the tension in her body and put her back into the mood until she wasn't as rigid as earlier. Then using a single finger, I gently pushed between her slit and felt around for where to put it.

"A-a little lower…" She guided, I did so and found an opening. "Yeah, r-right there."

I inserted a single digit slowly, feeling her wet entrance opening up. Gauging her reaction, she didn't seem to be in any kind of pain so I pushed another digit inside of her. This time she folded her legs, raising her knees a bit.

"Does it hurt?" I asked, noticing how she blinked hard.

"A little, k-keep going."

I finally put my whole middle finger straight in as my knuckles touched her vulva, feeling her wet warmth as her inner muscles pressed against me. Komachi looked fine so I started pulling it out half-way before ramming back in. Some of her juices were drawn out every time I exited her pussy, sliding down her body and leaving a dark puddle to form on the sheets.

In an effort to loosen her up a little before the actual thing I placed another finger inside, this time encountering more resistance. I felt around her vagina, getting different kinds of reactions as I touched various places, trying to look for the "sweet spot" or whatever it was that was mentioned a lot in works. I couldn't find it though, I guess it took an advanced skill to locate such a thing.

Now that she had plenty enough practice, I pulled my fingers out and positioned myself in front of her. Placing both of her legs on either of my sides, I then aimed my penis at her pussy and lubricated myself with her own fluids.

"Ready?" I asked, searching her eyes for any traces of doubt. She still appeared a bit reluctant, but with a deep breath she steeled her resolve and nodded.

"Ready."

I dug my penis into her pussy cautiously, knowing that its girth was much more than what two fingers provided. She winced in pain as I stretched her insides wide open with my boner while I inched myself deeper. It felt amazing, the blowjob from earlier paled in comparison to the pleasure of getting to do it, and bareback no less. To her however, it was a different experience…

"Hhngh… I-it hurts Onii-chan..!" Komachi cried out, a few teardrops streamed down her cheeks. I paused to let her rest until she was good to go again, pursuing my goal to put all of it in. Once she gave me her thumbs-up I resumed my journey inside her.

The walls of her vagina squeezed down on me as if they were trying to push me out of her, but I steadily slid myself in little by little until her outer lips were finally kissing the base of my dick. I heaved a deep sigh, fighting back the urge to not cum immediately. It may be hot and stuffy inside her, but it absolutely felt so good. Meanwhile Komachi gritted her teeth, doing her best to endure the pain of being completely penetrated as we celebrated the night we wholeheartedly surrendered our virginities to each other.

"How does it feel?" As much as I hated seeing my little sister suffer, knowing she did all this our sake truly touched my heart.

"Nng, it still hurts and it feels weird… I-I feel so full…" She reached out to me for a hug. "But I don't mind, and I'm happy so… c-can we stay like this for a while?"

"Sure, just let me know when you're fine so I can start moving, okay?"

We spent a few minutes silently connected, closer than siblings could ever be. I had wrapped my arms around her body, sensing her heartbeat against my chest. I could feel my own near to bursting, wanting to drown her in love that was only meant for her.

I had always been afraid to tell someone those three words, but now I could say them with my chin held up high.

"I love you Komachi." I whispered to her, tightening my embrace as I did. "Thank you, for always being there for me… for everything."

I wished there were better words to convey my true feelings for her, but I had always been bad at expressing myself properly. I could only hope that through those words and my actions, I could show Komachi how much she mattered to me.

"I love you too Onii-chan." She replied, her response alone enough to make me cry. "I'm so happy right now."

To think that all this time the person I'd longed for had since then been right beside me... Blood relations be damned, I love her and she loves me. Nothing in the world could ever change that.

After sharing a moment in peace, Komachi pulled away and told me it was okay to move. I pecked a chaste kiss on her lips once before laying her back down, holding onto her hips for support as I pulled myself out.

My withdrawal inflicted her pain again, but she said it was within bearable levels and urged me to continue claiming the discomfort had considerably died down from when I had put it in for the first time. As I inspected the portion of my penis that was now visible, I surprisingly didn't see any traces of blood. Maybe her hymen had been broken since she was an energetic girl, I doubt that bug had any balls to ask her out, let alone have a chance on Komachi.

I gently pushed myself back in, once more savoring the tightness of her pussy. With a slow pace I thrusted back in and out of her, Komachi's groans dying out until they were replaced with moans.

The bed creaked under our weight as my movements slightly rocked it back and forth, her breasts swaying along with our rhythm. My cock went harder at the sight of her absorbed in pleasure as we made passionate love, like a newlywed couple out on their honeymoon. Her body seemed to sparkle as the light in my room shone against the drops of sweat on her skin.

"Ah-! Onii-chan! I-I'm one with Onii-chan!" She began to match my thrusts by bucking her hips onto me, doubling the force she felt from being penetrated. My penis explored her deepest parts, paving its way as I pumped her full of my meat stick. Komachi and I composed our own symphony with her lustful moans, accompanied by the wet sounds of our private parts slapping together.

The build-up in my abdomen was a foreboding sign that I may finish before Komachi. As much as possible I wanted to make her reached climax first, but to do that I needed to up the intensity of pleasing her without increasing mine.

I let go of her waist to grant her more freedom in moving and placed my hands on her chest instead to hold them in place. I reached down to suck on one without breaking my hips' pace while alternating between squeezing the other breast and pulling her nipple. She arched her body once more from the simultaneous stimulation, gripping my hair tightly and yanking it that it felt like she wanted to scalp me.

"I-I'm almost there, mmn… Onii-chan, I want you to ki-kiss me…" I retreated from her boobs and engaged in another session of mouth-to-mouth exercise, using my tongue to probe her insides as well. A cocktail of our saliva was shared within the exchange, enough to throw me into a drunken stupor full of lust for her.

In the midst of fulfilling her request, I used one hand to reach down and tease her clitoris. As soon as she felt me rub it a muffled moan seeped through the corners of her lips. Seizing it between my fingers, pinching and pulling, Komachi's inside then started to coil around me. At that point I separated from the kiss and concentrated on my thrusts and her clit, focusing on sending her to the limit.

"Faster, d-do me faster p-please..!" She pleaded to me shakily. I obliged and plowed her as fast as I could, causing her voice to grow louder each time I made my entry. It didn't take long before her vagina clenched on my cock, intensifying the friction being produced between our genitalia.

"I-I-I'm cumming!"

As the huge wave of pleasure finally came crashing down on her, Komachi held onto me tightly and sunk her teeth on my shoulder. As convulsions shook her to the core while her body shuddered, I never stopped moving and completely ignored the sharp stinging pain as I too felt myself drawing closer and closer to orgasm.

Once I could no longer hold back I plunged my cock as far as I could into her pussy and finally ejaculated, spasms pumping out loads of my semen that had been backed up since earlier. I emptied out my entire stock, wringing myself dry of every single drop inside her. I shut my eyes and clung onto her for dear life as the warmth from the place we were connected at spread throughout my body.

The bliss of sweet release fogged my mind and I fell on top of her, fully drained yet absolutely satisfied. I remained within her, basking in the afterglow of our first time having sex. As mind-blowing as it was, for me the reason why it felt amazing wasn't the act itself, but because Komachi was my partner.

I mustered enough strength to kiss her forehead before I pulled myself out and moved aside so I wouldn't burden her with my weight any longer. She turned to face me, both of us smiling contentedly as we locked eyes.

"Can we remain a little bit longer like this?" Komachi asked, cuddling up to me. "I want to stay like this with Onii-chan…"

"Of course, even I want to have you close to me too." I pulled her into a hug. We spent a few minutes in peace until she spoke up.

"I'm sorry."

"Huh? What for?" I tried to face her properly but she didn't budge from her embrace, instead she buried her face onto my chest.

"Earlier, when I doubted you, when I said you'd regret doing this, w-with me…"

"Well, what's important is now, right? And I don't feel any regret at all. If anything, I'm happy to be by your side." I stroked her hair, she purred in content and nuzzled closer.

"I guess that's true… Thank you, Onii-chan."

"Are you feeling well? It doesn't hurt anywhere or anything?"

"Just a little, other than that I'm fine." Komachi then yawned, tired out from our little "activity".

I figured we could at least spend the night together since our parents weren't coming home soon. I had opted to take a quick bath but I was too tired and the same was for her. She said she didn't mind my smell either, so she insisted to wake up early instead and bathe together.

Well, how could I say no to that?

As I excused myself and was about to pull the blanket over us, we saw that my cum had been leaking from her pussy and had stained the sheets. Komachi apologized for the mess, but I reassured her that I'll clean it up tomorrow so that there wouldn't be any evidence.

"Or I could just y'know, keep this one bed cover hidden away somewhere as a memento." I said, tucking ourselves in. "For old times' sake."

"N-no, you can't do that, that's creepy! This is why girls don't like you Onii-chan, because you have weird, perverted fetishes." She chided, but I just chuckled at her reaction.

"Well, it's not like really need other girls to like me anymore now, do I?"

"Nnn…" Komachi blushed. "Y-you have a point there…"

"And there you have it. I don't want to keep you up any longer so, good night."

"…aren't you gonna say it again?"

Her eyes stared back at me, and from that alone I could tell what she wanted me to say. Maybe it was because we were siblings, or because we just had sex, or even my aptitude on guessing most things correctly out of context alone.

But I wanted to believe that it was something far greater, that it was because of the mutual feelings between us.

I knew most people, if not all, would frown upon the idea of us being together. I understood the dire repercussions of our actions, and how our bond as brother and sister was far beyond reparation. Yet despite all that in mind I discovered that Komachi was the only one for me, and we both took this path together.

That just goes to show how much I truly love her, and how she feels the same.

"I love you Komachi. Goodnight." I pecked a kiss on her lips, which curled into a smile that showed me her cute little fang.

I was no saint, and this didn't exactly conform to the "beautiful love story" that was typical of the norm, but to hell with all that. Love was never always a pretty thing anyway, and no matter how many times I was told ours was ugly, our feelings will neither waver nor change.

"Mhm, goodnight." She gave me a satisfied look before she yawned and finally closed her eyes to sleep. "I love you too Onii-chan."

A/N: Yes, I lied. I am a lewd man; did you really think I'll just end it there like that?

P.S.: お誕生日おめでとう, 比企谷 八幡.
