Chapter 4.

"I'm home" I announced, once I got inside of the house, seeing that mom was in the kitchen making dinner, and my sister was on the couch playing… huh, was that Drag-So Ball: Dragon WarZ?

Huh, I hadn't seen that game in ages, I thought I lost it years ago. But no, as it turns out... my thieving sister must have stolen it.

Sharing a look with my sister, she seemed confused for a moment, before looking back to the game… and I almost smiled as her eyes widened in fear.

"I- this is not what it looks like?" Tomoko said hesitantly, as she moved back into the couch cushions.

"We'll talk about you stealing my games later, grab the second controller. I'm gonna kick your ass" I said with a small grin, as I sat on the couch next to her.

The way her eyes lit up honestly made my heart swell, as she grabbed one of the old remotes from when the two of us used to play together when we were younger.

And then she quickly jumped up onto my lap, just like when we were kids, a look of happiness on her face as I registered as player 2.

But as I selected my character, Pickle the Demon, and started a match against my sister, I started to absolutely dominate her… until she decided to be cheeky.

The way her ass ground against my crotch was a lot less innocent than it was when we were children, and from the faint flush I could see from behind her, I could tell that she was enjoying it.

I tried to keep my attention on the match, but that momentary distraction was enough for her to clutch victory from the jaws of defeat, destroying my fighter with a large energy blast.

"Haha! I won!" Tomoko grinned, as she wiggled around on my lap, her surprisingly bouncy ass pressing against my slowly hardening member, "Ah…"

She quickly turned to me, and the look in her eyes wasn't comforting in any way, as she gave me a smug little grin, before bouncing against me ever so slightly.

Not enough to be noticeable to our mom who was just in the next room, but enough to have an effect on me.

There was a sinfully small barrier between the two of us, as Tomoko was still wearing her school uniform, meaning it was just her panty clad bottom against my pants that seemed to be straining under the pressure.

I looked into her eyes, and saw that they were very slightly hazy, and her face was becoming flushed with arousal, as she maneuvered her face towards mine.

Our lips were so close to connecting, and they were more tantalizing than I would have thought they'd be… the game was completely forgotten in this moment.

This was so wrong, absolutely sinful… but it felt so right, so as I moved forward to press my lips against hers, I was only an inch away when…

"Dinner's ready!" I heard mom announce from the next room, causing my eyes to widen and Tomoko to quickly jump off of my lap.

Taking a moment to reassess my surroundings, I then took a breath and walked over to the kitchen, where I saw that mom had made some sushi for dinner.

It was a bit awkward walking into the kitchen with the tightness in my pants, but I thought I hid it well enough, mostly standing behind benches or chairs as I got to the table.

Unfortunately, dad wouldn't be able to make it to dinner like usual, his job deciding to keep him back into the night.

"So, Ryuuji-kun, how was your first day of the school year?" Mom asked with a smile, as she picked up a piece of sushi and ate it.

"Oh, it was good-" I started to say before noticing something pressing against my crotch.

It was rather rigid, and I thought it had some sort of cloth on it, though I could also tell there were also some other things on it that were gripping against my semi-hard dick.

Sharing a look with my sister who was sitting across from me, I saw that she had a small blush as she gave me a small grin.

…Yep, that was her sock-covered foot grinding against my cock, and from the way she was huffing? She was into this sort of thing.

So I quickly took my own foot and pressed against her crotch, causing her eyes to widen in shock, before noticing that she was already damp.

"I- yeah, today was pretty good. Though I think you should ask Tomoko-chan that instead, from what I saw? She made a friend" I said with a smile, causing mom's eyes to light up as she looked at my little sister.

"Ah? Is that so, Tomo-chan? Tell me all about it!" Mom said happily, as my sister struggled to answer.

"I- I uh, um…" Tomoko stuttered, as she looked at me, before increasing the pace of her ministrations.

It likely wasn't helped by the fact that I'd managed to move her panties to the side, and now my foot was pressing against her bare, somewhat hairy pussy.

I felt a sudden wetness when my foot pressed against her vaginal lips, and due to specifically listening out for it, I heard a slight shlicking sound from underneath the table.

"I- yeah, well… um Kone- Koneko-chan is a year- year younger than me, and- I well… I thought ahn, um that she could- could use a friend?" My little sister said hesitantly, stumbling over her words every time I moved my foot.

She of course would counterattack, and would rub her foot along the length of my cock, it was as if she was trying to measure it with her feet alone.

"Well, that's just wonderful to hear! I'm sure that you'll be making more friends in no time" Mom said happily, as she finished off her dinner, and got up to leave.

The two of us quickly stopped what we were doing as she got up, just in case she saw anything.

It was a tense few moments, watching as mom walked out of the room and closed the door behind her. Then the two of us listened quietly, as she walked up the stairs to her bedroom.

And after she closed her bedroom door, I heard the telltale sound of that door being locked.

"So…" Tomoko started, as she nervously looked away from me.

"I love you so much, Tomoko," I said with a smile, as I looked at my little sister.

Her face grew a cherry red as she stared at me for a moment, before a smile blossomed on her face.

"I- I love you too, nii-chan" She told me shyly, and that mixed with her words caused whatever composure I had left to shatter.

Quickly, I crossed the gap and locked lips with my precious little sister.

She tasted like sour candy of all things, it was a citrusy taste, but as I ran my tongue over her lips, I couldn't help but like the taste, it was enjoyable in its own way.

Tomoko opened her mouth allowing my tongue to enter inside, experimentally tasting each other as we intimately held each other in the dining room.

After what felt like a lifetime of kissing my sister, she removed her lips from my own, taking a deep breath.

"Should… should we move this to somewhere else?" Tomoko asked breathlessly, as she stared up at me.

She was quite a bit shorter than me, and just to kiss her I had to crane my neck down… while she had to stand on the tip of her toes.

"Yes," I almost growled out, as I picked her up in a princess carry, causing her to nearly scream in shock.

Thankfully she covered her mouth just in time, muffling the sound and ensuring that we wouldn't wake mom up.

With that, I carried her all the way to my bedroom, making sure to be quiet. Opening the door, I then laid her on my bed before returning to the door.

I made sure that each and every lock was… well, locked. Before looking back to my sister, who had in my momentary distraction, completely stripped of her clothes and was laying on the bed completely naked.

She had a small smug look on her face, and I couldn't help but stare at her ass. It looked so big on her frame, and was larger than her entire torso… then again my sister was a rather small and slim girl.

"So, what are you going to do to me, bro?" Tomoko asked with a little grin, as she swayed her hips a bit.

Looking at her up and down, I gave her a smile at the sight of her naked petite body.

But then I remembered that she had stolen my game, keeping it from me for years… and that needed some punishment.

"Well, Tomoko-chan… I know exactly what I'm going to do" I said with a breathy tone, as I positioned myself behind her, causing her to let out a small gasp of excitement.

"Ooh? What are we going to- ah!" She quickly moaned, as I slapped her right asscheek, there was no ripple but it did bounce quite a bit, "Spankings then? Oh! I've been a bad bad girl, big bro"

And unsurprisingly, she was completely into it… why would I expect anything less from my degenerate little sister?

"Count them," I told her, causing my little sister to give me a small nod, before giving me a small smile, one that I returned… before rearing my arm back.

"A-alright… o-one!" She cried, as I smacked her left asscheek this time, the bounciness and softness of her ass making for a rather smooth experience.

Then I switched sides, smacking her once again on the right cheek, causing her to let out a quivering moan.

"Twooo~ Oh, this is… this feels so strange! Big bro, you're making me feel so weird!" She said, laughing deliriously as she was… probably quoting some sort of hentai she watched or read.

"Don't worry sweetie, it's going to be okay. Your onii-chan's here after all," I said soothingly, before I spanked her yet again, causing her to lock up a bit, and I could suddenly smell a rather sweet scent, "…Did you just come from that?"

"S-shut up!" She groaned, as she weakly turned back to me, "That- that just hit like three of my fetishes…"

"Well, I guess it's time to hit more of them," I said, before smacking her yet again, "And don't think that I didn't notice that you stopped counting. From the top"

"One! P-please, spank me harder big bro!" My little sister cried out, as I slapped her ass yet again, "Two!"

I continued to spank her until her ass was beet red, a process that she thoroughly enjoyed.

And once I felt that she was sufficiently punished for her crimes, I stopped and stared at her.

"Hehehehehe" She laughed deliriously as she buried her face in one of my pillows, a rather large wet mark underneath her. It was just now that I noticed that I'd probably have to clean mybedding after all of this.

"Are you okay?" I asked, causing her to slowly turn to me.

"My ass hurts so much… I love it~" She said as she tried to get up before slowly collapsing back in the bed, "I don't think I'm going to be able to walk tomorrow… love you, big bro"

"I love you too, Tomoko… now, don't give up on me here. We still haven't gotten to the main event" I told her, causing her to instantly perk up and look at me with wide eyes.

"Do- do you mean?" She asked, as she looked down at my still clothed lower body.

"Yes, sex. Hot and hard babymaking sex" I said, as I unbuckled my belt and pulled my pants and underwear down, exposing my eleven inch long thick, hard, and throbbing cock.

"Whoa," Tomoko said with some sort of reverent awe, as she tried to reach out for it, before just falling short, "It's so much bigger than I even imagined"

I couldn't help but smirk at that. After all, what man didn't want to get complimented on his size?

The last time that she'd seen my dick, that I knew of at least, was when the two of us were little kids and bathing together. I only had five inches back then.

"How- how is that going to fit?" She asked, staring at my cock like it was some sort of divine relic.

Honestly, knowing her? She was likely going to try and make a religion out of this.

"Well, that depends on how wet you are," I said, causing her to give me an incredibly shaky grin.

"Oh, I'm pretty sure if I moved from this spot? Our house would become a tourist location for a new waterfall… hehe" Tomoko said a little bit awkwardly, causing me to grin.

She then moved a bit so she was now laying on her back, exposing her bushy pussy for my eyes only, it was already slick with her love juices, and awaiting for me to enter it.

I could also see her asshole, a little fleshy ring that twitched as the cold air of my room moved against it.

"Hehe, what a perv, ogling your little sister like you want to make me pregnant… so gross," She said with a little grin, but from the look on her face? I knew that she desperately wanted this.

"So you're wet enough for me? That's perfect then," I told her as I grabbed onto my cock, and started to move it towards her entrance, and once I was lined up I gave her one mighty thrust.

Instantly, my cock was enveloped in the warmth of my sister's pussy, it was tight and I could feel her vaginal muscles squeezing me with all the force she could muster.

"Agh! Oh- oh Kami! Don't you ever pull out of me!" Tomoko cried out, as she locked her legs around my waist

It felt like I was always supposed to be in here, my sister's tight snatch perfectly fit my cock.

Honestly, why would the laws of this world ever try to deprive me of such… such wonder?

"Nothing could make me pull out of you, Tomoko," I said softly, as I thrust deeper into her, causing her to let out a deep and guttural groan that didn't fit someone of her size.

But even so, it was one that was muffled as I locked my lips with her own, the two of us swapping our saliva as our tongues clashed against each other.

I could see the sheer joy in her eyes as I made out with her, before interlocking my fingers with hers, the slight flush on her face growing brighter.

Then I ended the kiss, leaving a small trail of saliva as the only thing connecting our lips together, as I looked down at my sister underneath me.

She was a panting and sweaty mess, and yet… she has never been so beautiful to me.

"Hah, hah… I- are you close?" Tomoko asked, after taking a few moments to catch her breath, as she looked up at me.

I just shook my head, before thrusting further inside of her, practically hitting her womb and causing her to nearly scream out in surprise.

Her scream was only stopped when she in a split second decision, bit me on the collarbone, screaming into my flesh as she did so.

I was fairly sure that a bit of blood trickled out, but that little bit of pain was almost negligible in comparison to the pleasure I was feeling.

"Hehe… you belong to me now~" My sister said a bit deliriously, as she let go of my flesh with a little pop.

And I just knew that was going to leave a mark on me, damn it, Tomoko. I have school tomorrow!

"Well then, I guess all's fair in love and war," I said after a moment, before lunging forward and biting my sister's own collarbone, sucking a bit before letting go with a pop.

Looking down at her, I saw that she was completely and utterly red, it was as if I'd just proposed to her or something.

Then, I felt her pussy constricting against my cock, before it started to convulse, spasming around me.

"Did- did you just come from that too!?" I asked incredulously. Seriously, this girl… she was such a degenerate and I loved it.

"I- that was just… just so hot! D-don't blame me! I didn't even know I was into this!" She cried out, covering her face with one of her hands, making her look just… utterly adorable.

I couldn't help but smile, as I looked into her eyes. There was embarrassment sure, but there was also some sort of obsessed fervor in her vibrant green eyes.

And that sort of thing just made me even harder.

So with that, I continued to thrust into her, going faster and harder as I could feel something coming up to the surface.

"Get pregnant! Get pregnant! Get pregnant!" I groaned, as I continued to pound into my little sister's cunt.

"Yes! Yes! Breed me, big bro, make me pregnant! I'm going to be a teen mom! We're going to have hot kinky pregnant sex! Then- then we'll raise our kids as your little fuck pets!" My sister exclaimed manically, as she scratched and clawed at my back, her legs still locked around my waist, ensuring that I couldn't escape.

I wasn't all that sure about that last part… but it didn't matter, as I could feel the release coming.

And then, with one last and final thrust, I emptied my load of thick, hot baby batter directly into my sister, painting her insides white.

"Uuuungh! Yeessssh!" My sister groaned out, the upper half of her face flushed a deep red, her eyes wide in orgasmic pleasure, sweat pouring down her face, and tears in her eyes, as drool dripped off of the tip of her tongue, as she raised her hands before giving me the peace sign.

Of course my sister would know how to do an ahegao on command.

But I didn't think about that for much longer, as I continued to empty my balls directly into my sister's eagerly awaiting womb.

And when my nuts were completely emptied, I just laid there, covered in sweat and sexual juices with my perfect little sister, holding her in a loving embrace.

The two of us stayed in that same embrace for the rest of the night.

Miki Hyoudou:

Listening to the sound of my children having sex in their room, I couldn't help but muffle the sound of my own moans, as I fingered myself.

Gorou hadn't been able to keep me company for the past couple of years, since his work wouldn't let him go until the next day started… and that had put a small amount of strain on our marriage.

Nothing that couldn't be fixed with a long and hard dicking, but most nights he was just too tired and wanted to go to sleep. So I've had to use my trusty toys to keep me company on those lonely nights recently…

But now that my kids are going at it? Hearing their moans and professions of love for each other through the thin walls of the house, I couldn't help but finger myself.

Tomoko was such a lucky girl, I knew that my little Ryuuji-kun was going to make whatever girl he was very happy. He definitely inherited that size of his from his father.

And as I caressed my clit to the wet hot sounds of sex, I couldn't help but smile. At least now Tomoko was going to have a husband who loved her… hell, a husband in general is more than I expected from her.

Don't get me wrong, I love my daughter. But she's completely hopeless when it comes to people. Reminds me of how I was at that age…

But I was lucky when it came to Gorou, and I didn't think that she'd get that same sort of luck.

Was incest frowned upon? Of course it is, but they're my children and I know that they'll be responsible.

Even if they have to adopt… at least they'll be able to have kids.

Listening to my son telling my daughter to get pregnant, well that was a bit of a shock. But that… that should be fine.

It's not like she'll actually get pregnant on her first time.

So with that in mind, I continued to listen to the muffled sounds of my children mating with each other like beasts in heat throughout the night.

Even when Gorou got home, he was so tired that he didn't even notice the strange noises and fell asleep.

Feeling his breath behind me, it felt quite a bit more taboo and just gave me such a rush as I continued my ministrations.

This was way better than just watching porn.

-----

Back to Ryuuji Hyoudou:

As I laid against my sister, who had thankfully fallen asleep after the fourth round, I heard a loud tearing sound, causing me to blearily look around.

Then I remembered that meant that I didn't get something again… or at least that's what I believed happened.

I sat up in the bed, causing my sister to grumble a bit, as she was still holding onto me, but eventually she quieted down.

And then I heard another tearing sound, which was kind of annoying.

Sorcery - Divination (One Dot) World of Darkness: Sorcerer Divination (100 CP)

The ability to gain information by occult or magical means. Might mean staring at a crystal ball, drawing cards, or casting wands.

[1] Sorcery of this level allows the user to see one week into the past or future with an overall sense of accuracy.

Thought Acceleration Tsukihime Lore (200 CP)

Even a human brain operating at peak capacity has its limits - it is, after all, what amounts to biological hardware with set limitations. But what if those limitations could be surpassed? You are able to accelerate your thought processes to twice their normal speed, letting you quickly multitask and react faster than body and nervous system would normally allow, running calculations and strategies in a blink rather than a minute. In time, you could even accelerate this to three, or four or more times in speed. However, much like overclocking a computer, this is a stressful technique that is exhausting, and if overused, can burn your brain out like an overheated engine. Practice and careful moderation may let you overcome this, but for now, be cautious in how you use this.

But right at that moment, I felt more knowledge get inserted into my mind.

There were two different sources of knowledge that made themselves known to me.

The first, was how to… divine things, seeing the future, along with the past through various mediums. From crystal balls, tarot cards, or something else.

Now, these divination visions weren't infallibly the future, things could still be changed. And the visions could be lacking context for the past, making everything a jumbled mess. But this seemed generally pretty useful.

I could only see up to a week in the past or future though. But this was still kind of awesome. After all, this was like… an actual spell.

Then there was the next one, which was honestly weird. It made it so I was able to accelerate my thoughts, thinking far faster than I should normally be able to.

I'd be able to multitask a lot easier, and react faster than my body would normally allow, it'd let me think up complicated things in nearly an instant instead of needing to take actual time to be able to have those thoughts.

This was honestly pretty damn good, I could definitely see some great usage with this new spell.

And I knew inherently that I could turn my newfound Divination and Thought Acceleration Spells into… Visions.

Wait no, that wasn't the correct terminology. I'd be able to place my spells into objects, but they… weren't Visions?

That was weird. But once that was all over and done with, I laid back down, pressing my body against Tomoko's, smiling as she cuddled into me.

I'd had a rather stressful day after all, with the whole magic is real thing... even if the night was far more comforting and pleasant.

Closing my eyes, I listened to the sound of my sister's heartbeat… and her cute little snores. It was oddly soothing in a way.

And like that, I had fallen asleep in the arms of my little sister.
