The Erotic Mind-Control Story Archive

According to the text she had sent me, Jenny planned to visit by train. She also informed me that she had booked a room for staying overnight, since she would arrive pretty late, at a decent hotel not too far from the trendy Italian restaurant that she had suggested we should try out. I offered to pick my little sister up by the train station so she would not have to walk too far by herself, I figured I should at least attempt to behave like the nice older brother that I aspired to be.

Before heading out, I made sure to style my hair to the best of my ability and to spray on some cologne. I also made certain to thank whatever lucky stars that had arranged for me to have been gifted an outstanding quality suit just earlier today. The man that left my apartment certainly looked dressed as though he was going on a date with a beautiful woman, or at least to an important meeting. And to me—this was important! I wanted to do my absolute best to improve the since long spoiled relationship between me and Jenny... well, the “Simulacrum-Jenny”, now that she finally seemed to be willing to give me a chance. When we had talked on the phone earlier, she had seemed a bit off from what I knew as her normal behavior, but I had no real idea how much this version of Jenny could have changed. I recalled that Azrael had mentioned something about how a Simulacrum would be forced to cope with my influence over its soul or something like that. I briefly thought back to how the Simulacrum of Xue Mei had seemed unable to stop staring at my crotch after I had taken her. Stolen her soul, claimed her... Well, I guess I would have to figure out the deal with these so-called “Simulacrums” as I went along. In any case, I looked forward to eating some good pasta; I felt hungry!

I headed out of my apartment and to my surprise saw that Xue Mei was also waiting for the elevator, same as she had been doing a few days ago. ”No, not Xue Mei—her Simulacrum.” I corrected myself. “The real Xue Mei was my catgirl ninja slave now. Life had sure become weird.”

“Hi Xue Mei!” I waved at her while I approached.

“O-oh... hi...” She responded with a much weaker voice than I had expected. She looked immensely tired, as if she had not slept good for a week. Her black makeup was sloppily applied and she seemed to shiver as if cold, despite the oversized hoodie she wore. “You look ummm... handsome today?” She continued in a half-question, half-statement.

“Thanks! Yeah, it’s unusual for me to dress up like this, huh? I like it though! How are you?”

“I’m okay... J-just been having a lot of w-weird dreams lately.” The Chinese girl tentatively answered while both of us got in the elevator.

“I see. Perhaps you should go see a doctor, then? Even I can tell you look kind of tired, Xue Mei. Are you feeling sick?”

“Umm... A-actually I think maybe this could be fixed if we could go on a date together? Like, r-right now?! I think that would absolutely help!! I... I’d really like if we could go out like you suggested a few days ago when you uhh... grabbed me from behind!!” Xue Mei’s words came out so fast that she stumbled on them. While her voice sped up, her eyes wandered across my body, as if unable to focus. She reached for me with a trembling arm, sounding absolutely desperate.

“Let me think about it.” I replied with a smile. “Actually, I’m on my way to a date with another girl right now. I’m really looking forward to it!” I continued, with a laugh. I saw no reason to tell her it was just a dinner date with my sister.

“...I hope... you have fun...” Xue Mei stuttered in an almost inaudible whisper. It was as though I had shattered her hopes and dreams.

“Well, good to see you, Xue Mei. Let’s talk more later, huh?” I said while I pushed past her and hurried out of the elevator. In what must have been frustration over the rejection, Xue Mei bit her lip. Hard. Drips of crimson blood mingled with her black lipstick. To be honest, I didn’t give much of a shit about what was going on with her (or “it”) anymore. Thanks to the powers of the Soul Deck, I could have a hotter version of my girl next door whenever and however I wanted. Why bother?

Jenny was sitting on the side of a fountain outside of the train station, her arms crossed, when I—late as usual—finally found her among the crowd. It was weird for me to see my Korean little sister with normal human proportions and clothes fit for use outside of a porn shoot. When she saw me hurry towards her, her eyes were also filled with a lot less unconditional love and adoration than what I had grown used to, and instead more of her trademark simmering anger at me keeping her waiting. At least that’s how it looked to me.

“You are late!” She pouted at me, her arms folded just under her small chest.

“Sorry, sorry! I had a few things to deal with this afternoon. Great to see you, Jenny!” I said as I, without really thinking before I did so, gave her a hug. It was the first time I had ever greeted my sister by hugging her, we did not really have a hugging sort of relationship. Well, until I had forcibly changed it with magic, that was.

When I wrapped my arms around my little sister as she sat beside the stone fountain, I felt her body go limp and she gave a small surprised gasp. When I let go, Jenny’s face had turned red as a beet. She sat atop the fountain seemingly in shock while she looked down at the ground, mumbling incoherent words that I somehow interpreted to be meant to tell me that my suit looked nice.

While Jenny was busy panicking over my public display of affection, I took the time to check her out a bit more closely and noticed that her clothes did in fact look a bit unusual on her. She wore a red sweater that tightly hugged her upper body, a short black skirt which showed off part of her thighs not covered by black thigh-high stockings. Her slightly wavy hair was done up in twintails, a hairstyle I had never seen on her before. Then, it suddenly hit me! Wasn’t she... cosplaying as that tsundere mage from that super famous old visual novel?

“Thanks! Yeah, the suit is new.” I told her with a smile. “Nice clothes by the way, Jenny! They look... familiar somehow?”

“H-huh? Ummm... no, it’s the first time I wear them! I figured the combination would be stylish. I-it is, isn’t it?” She replied, shyly tugging at the hem of her skirt while she still sat down, seemingly oblivious to what I was hinting at.

Was Jenny... unaware that she was dressed in a cosplay getup? Either she tried to hide the fact that she had dressed up in cosplay to meet me, or she was oblivious to the fact. The character was so popular that she must’ve seen her before, so unconsciously buying similar clothes and styling her hair that way was not out of the question. Either way, the way she awkwardly fidgeted with her skirt while blushing was adorable!

“Absolutely, it’s a really good look for you, sis!” I affirmed.

“I’m glad you like it!” The compliment seemed to have caught her off-guard. Jenny looked up at me with a big smile, still blushing, and then suddenly stood up! “Anyway, enough waiting around. Hey, let’s go! I’m starving!” She struck an awkward pose while she said this, pointing her finger up and forward in the air and froze in place, as if imitating a pose and catchphrase that a ditzy girl would do in a manga. She held the pose for a few moments too long, just standing there.

“Yeah, I... uhhh... I agree, let’s. My car’s right around the corner. I’m starving too!” I replied, trying my hardest to appear unfazed—I had expected “Simulacrum-Jenny” to act more like the “normal Jenny” I knew from before. From our short exchange so far, it seemed as if the Attributes that I had forced onto her soul when transforming her into my “Loving and Energetic Little Sister, Jenny Sakamoto” had really done a number on the poor girl in front of me. I would be lying if I said I didn’t appreciate it, though.

I took my (perhaps unwittingly) cosplaying little sister’s hand and began leading her to my car. As I gripped her hand tightly, I swear I could almost hear her heart beat hard and fast inside of her small chest.

I led the Korean American beauty by hand to where I had parked my beat up old garbage heap of a car. Jenny was way too good looking and well-dressed to be seen in such a trashcan—heck, even I looked too sharp for it in my current state. I opened the door to the passenger seat and guided Jenny inside. When I sat down in the driver’s seat and started the engine, I noticed how Jenny looked at me with big eyes.

“It’s been... a long time since you drove me anywhere, hasn’t it?” She asked, intently gazing at my face.

“Huh? Yeah, I guess. You got your own driver’s license pretty early.” I replied, popped the stick in reverse and began to slowly drive out of the parking lot.

“Thank you for this...” She mumbled, once again nervously fiddling with the skirt and now also her twintails.

“Don’t mention it, sis, you know I’m glad to assist you. It’d be a long walk from the train station, especially considering you’d need to lug that heavy bag around. What did you bring with you anyway?”

We drove out of the parking lot and onto the street while chatting.

“I’d have been happy to drive you around more when we were kids, y’know? But you had little interest in hanging out with me back then, remember?” I smiled at her while I mentioned this.

“I... ummm...” It seemed as though she didn’t know how to respond to what I had just said. Jenny kept fidgeting with her hands while her breathing got more and more heavy. I remained quiet but no reply came. Instead Jenny continued to stutter nervously, her chest heaving more and more, as if she would start to hyperventilate. She seemed equal amounts nervous and bothered by what I had just said.

“Errr... anyway! I’m really glad you want to hang out today! You did good at a tennis tournament, huh?” I said, finally giving her an out. I did not really grasp what Jenny had been going through just now, but clearly our past seemed to bother her.

“O-oh, yeah!” Her breathing calmed, as though she was relieved I had moved the conversation to a more comfortable subject for her. “This last week or so I’ve been feeling really good whenever I’m on the court. It’s like, I feel like I’m faster than I used to be! I’m like the main character in that old anime, Princess of Tennis.” She laughed. She always had a wonderful laugh. “You remember it?”

“Hell yeah, of course I do! You used to love that show!”

“Uh-huh! Oh, guess what! You won’t believe this but I... ummm... I started to watch some anime again recently.” Her voice suddenly full of passion, she brushed one of her carefully tended twintails aside as she leaned towards me.

“Really? What anime?!” I asked with genuine surprise.

She listed ten of the currently airing anime. ”That was way more than what I was watching!”

“That’s... surprising.” I replied. “Can that really be considered as ‘some anime’ though? I’d say it’s a ‘whole lot of anime’ you are watching, Jenny. And some of them are really ecchi shows too! I thought you hated that stuff? What’s happened to you, sis?!” I asked, feigning shock.

“Hey! Don’t be mean... I thought you would be happy to hear about my rekindled love of anime! I’ve even started playing some old video games, y’know?!” She stuck out her tongue at me. “Oh oh!.. I see my hotel! Do you ummm... mind if we stop by my room there first?”

“Of course not. Let me help you carry your bag, sis.”

We rode the elevator up to Jenny’s room in silence. She had apparently booked a luxurious suite for the night, using most of the prize money from the tournament. It reminded me that she had always been a bit too eager to waste money on needless luxury. Not at all like me who spent my money on valuable stuff such as half naked plastic figurines and digital pictures of 2D babes... She opened the door to her suite and I followed her inside to drop off her bag by the side of the bed. When I put the bag down, I noticed that Jenny had sat down on the bed behind me, seeming to be nervous about something.

“Umm...” She began, while I still stood next to the table I had put her bag on, my back turned to her.

“Yeah?” I replied without turning around to look at her.

“Brother, I... ummm... I’ve been having so many new thoughts and ideas, lately. I swear I wasn’t planning to bring it up because I feel too ashamed, but... b-but after what you said in the car about how I didn’t want to be with you before, I cannot ignore my feelings anymore! I n-need to tell you!!”

She swallowed, pausing to gather courage. I waited patiently, silently, my back still turned.

“Brother, I... I am sorry for always being such a mean bitch of a sister to you! I feel... so fucking bad about it! Just thinking back on how badly I’ve treated you... I feel terrible!!” Her voice broke. She hesitated slightly, as though she did not know how to continue. Then, more words came pouring out of her. “No, that’s not correct either! Fuck!! It’s... it’s not just because of how badly I’ve treated you. It’s... it’s shame, brother! So much shame over how little I have done to satisfy you—to please you as your little sister!! Just thinking about it... my chest hurts! My heart feels like it’s tearing apart!” Her voice was trembling.

Holy shit! I turned around to see Jenny, in her cute cosplay outfit, crying on top of the bed while she was looking straight at me.

“Hey, Jenny, don’t cry it’s—”

“P-please, let me finish.” She began bawling. My Korean supermodel of a little sister did not cry gracefully at all.

“All my g-goddamn life, I’ve wanted to please you. I freaking love and adore you, brother! How c-c-could I have misunderstood so much about myself until now?!” She looked straight at me through tear-filled eyes, confused, as if she was hoping that I would have the answers to her questions. I did of course, but I saw no reason to share them.

“Sis,” I took off my suit jacket and sat down next to her on the bed. “I’m very glad to hear you tell me this. I... am happy to know that you actually care so much about me.”

“I don’t just care, stupid brother!” Her eyes were still filled with tears. “I want to—no! I need to!—be desirable and pleasing to you!”

As she said this she embraced me from my side, both of her slender but slightly muscular arms wrapping hard around me. She lifted her lithe legs from the floor to the bed and leaned her entire weight against me, holding on to me as if I were a stable rock amid a stormy sea. I responded to her desperate embrace by gently patting her head, brushing her long silken twintails with my hand.

My sister getting the headpats she was programmed to love—her soul was programmed to love—got precisely the reaction out of her that I was hoping for. Jenny snuggled herself even closer to me, her whimpering and crying slowly dying out, to be replaced by a content and calm breathing.

I kept patting her head while my little sister pressed her soft yet strong body into me to find comfort and safety. Her breathing was calm, Jenny was at peace next to me. She had no way of knowing that the magic I had used to capture and change her very soul was the very reason she was in need of my comfort and safety. No way to know that her feelings were manufactured—artificial emotions forced upon her by dark arts she was powerless to resist. Naturally, I got hard just thinking about this. Jenny stirred as she noticed how my hard member pressed against her stockings-clad thighs, through my dress pants.

“Sorry—” I began to apologize.

“Don’t apologize. Feeling you like this makes me... happy. I think?” She replied. She then began to slowly move one of her black thigh-high-clad thighs teasingly up and down against my dick, rubbing it through my pants.

“H-hey... we are siblings, Jenny. What are you doing?” I asked, pretending to give a shit.

“I’m doing what I want, brother. Pleasing you.” She simply replied as she pulled off her red sweater over her head, revealing a sexy pink lace bra underneath.

My sister, her tears still drying in her eyes, pushed me back so I was laying down on the spacious hotel bed, and then she climbed on top of me. Still rubbing against my dick with black stockings and thighs, she began to take off my pants with one hand while the other nimbly unbuttoned my shirt. With regrets, I had to admit that it seemed as though my sister Jenny had a lot of experience in undressing guys...

“I don’t care about anything else. Just... this. Just my brother...” I heard her whisper to herself, as if she needed to reaffirm her feelings to herself. While she did so, she rubbed her legs and herself up and down across my hard shaft, pressing up against it through my underwear.

“Fuck! I’ve always wanted this, Jenny! I’ve always wanted to see you to act like the whore I’ve known that you actually are, solely for me!” I told my Korean little sister while I groped her toned legs and tight ass with my hands, squeezing them hard.

“I just wanted to be noticed by you, brother! Please, let me finally be your slutty little sister...” She confirmed with a moan, beginning to take off my underwear.

I took a moment to admire my cock-hungry, now turned brocon, of a sister, while I fondled her body. She was still mostly in her cosplay as she straddled me, her pink bra being the only thing that was off-model. It was such a turn on that she did not even seem to realize that she was acting like a dirty cosplay whore for me right now.

I moved one of my hands from her legs up towards her crotch, under her skirt and pulled her panties aside. I was not even surprised that Jenny was wearing a thong under her skirt to her date with me. Whore underwear seemed to be the standard for this Asian slut. I slid my finger inside her wet snatch while she hungrily continued to grind on my now naked rock-hard dick, still using her legs.

“Take your off bra, Jenny. Show me your slutty tits!”

My sister was happy to comply, quickly freeing her breasts from their constraints. She moaned as I teased her cunt with my finger and she threw her bra to the side of the bed. Compared to the ripe melons I had gotten used to see flop around on her, her breasts were a pathetic size, but for an Asian girl she was actually quite big. Her size surprised me! Seeing my satisfied expression at her reveal, Jenny licked her lips; she needed more than just my finger inside of her.

“Wait here, just like this, brother. I’ll go get us a condom from my bag.” She whispered to me, her voice dripping with desire.

“No.” I held her by her hips, preventing her from getting up. “I want to enter your right now. Like this.”

“But—” She tried to protest.

I began guiding her gushing pussy towards my dick, still pulling her thong aside. Jenny was moaning like the slut she had always been while her hips quivered from the excitement, making no effort to stop me. No matter if she was fake or real, seeing the girl that still looked and talked exactly like my little sister changed into a whore desperate for sex and my attention made me tremble. I felt the warm outline of her pussy against the head of my dick; it felt like heaven.

“Yesssss....” She moaned when I slowly slid her wet pussy down on my dick. As I impaled her, she began rocking her hips back and forth, squeezing me. Jenny was just as tight as I knew she would be.

With my little sister moaning on top of me, I sat up and embraced her while she was slowly gyrating her hips. I pulled her head towards mine and we met in a long kiss. When I kissed her, I felt how her pussy twitched and quaked as she squeezed, her strong muscles from years of sports doing their absolute best to satisfy me. When we finally broke the kiss, Jenny held her face close to mine. Tears filled her eyes once more.

“I... I love you, brother. I love you so fucking much! I understand now... I finally understand...” She moaned while she was grinding her pussy against me. Tears of happiness streamed down her cheeks.

“I love you too, Jenny.” I replied and brought out her card from the Soul Deck and summoned her. I needed to try this!

For a brief moment, it was as if a mirror had been shattered, reflections of the girl I was fucking splintered into a million pieces. Then, reality adapted to the change I had forced and I was suddenly knocked back from my sitting position to my back landing hard on the bed! The “real” Jenny’s sudden appearance and the rapid expansion of her previously modest bust to enormous balloons had left me no space to remain sitting upright. Being knocked backwards by an expanding wall of soft boobs was quite the experience.

“Ahn~ Onii-chan? Na-nani?” the girl moaned—she had materialized with my hard penis already inside of her. She wore the same joke of a schoolgirl uniform as usual, her miniature panties pushed aside to facilitate my entry, just like the other Jenny’s thong had been. Her breasts were shaking back and forth from their impact with me, gravity-defying and spraying her body with slick oil-like milk as always.

“God, you are so fucking sexy, Jenny,” I grunted, grabbing my titty monster’s slim waist. “Your brother needs his little cocksleeve.” Grabbing her by her waist, I began almost jerking myself off by lifting and moving my little sister’s small body up and down my shaft while I remained on the bed. The motion set the still confused but extremely horny girl’s expanded breasts bouncing up and down, spraying even more milk as they were wont to do.

“O-onii-chan! Yes! Kimochii! Fuck me this hard~! Treat Jenny like your warm little sister onahole!” The girl begged me, doing her best to aid me in my rhythm, feeling the full pleasure of being repeatedly impaled by the man that was her whole reason for being.

Eventually, I got up from the bed, grabbing Jenny by her ass, pressing myself against her voluminous boobies as I screwed her hard against the wall opposite of the bed. She was in heaven, wrapping her legs around me, screaming and begging me for more after every thrust. When I felt I was getting close to releasing inside of the idealized anime whore of a little sister I had created, I brought out the card and unsummoned her.

Now I held the other Jenny against the wall, her twintails in a disarray, her smaller, naked chest pressed up against me as she had wrapped her legs around me. Her skirt, whorish cosplay stockings and thong were all a mess. She was not covered by any milk, though.

“God, yes! I need it! Come inside your little sister’s slut cunt!” She whispered as she bit my ear, Jenny’s voice breaking from ecstasy. Hearing her beg for it made me finally give in; I came inside of her. Jenny’s body tensed and shook in response. Her legs cramped against me as she moaned my name and called me her big brother time after time.

Finally, Jenny’s body settled, and collapsed against me. She began crying yet again as she held on tight, resting her small body against mine. I carried her to the bed and while she still held on to me, as if worried I would disappear, we drifted to sleep together.

When I woke up, Jenny still laid next to me, simply looking at me with her almond-shaped eyes wide open. She met my eyes and gave a wide grin.

“Good morning.” She smiled at me.

“Hi Jenny. Shit, what time is it?”

“Shhh... it’s still early. We missed our dinner reservation, but ummm... if you ask me, it was totally worth it.” She winked playfully at me as she stroked her hand across my chest, her nails scratching me teasingly.

“Yeah, that was pretty crazy.” I began patting her head.

“Yeah, I figure... family reunions will be both weirder and more fun from now on, then?” She purred as my hand brushed across her dark hair.

“Sure will. Hey, tell me, did you feel good or what when I grabbed you by the waist and pinned you against the wall earlier?”

“Hell yes, you made me feel so goddamn good!” She pushed her head into my palm like a cat getting pet, as if she could never get enough headpats. She couldn’t. “To be honest, I felt so great that I can barely recall whatever you did to me. I never suspected my ‘dorky’ older brother would be such a freaking sex guru!”

I brought forth her card and summoned the real Jenny.

Except for the hairstyle, clothes and the severe amounts of added mass onto her chest, she looked identical, hugging me in the same way. Looking at me with the same loving eyes. I felt as though the two versions of Jenny were almost in sync.

“Good morning, my cute little imouto.” I smiled at her, combing my fingers through her hair.

“Ohayo, Onii-chan!” She laughed a bubbly laugh. “You finally called me your imouto! Yatta!”

“Yeah, yeah, you colossal weeb. Tell me what you remember from yesterday.”

“Eto—, you mean after you let me share your shower? I remember Onii-chan using my body, first on this bed, then against the wall. Jenny felt... really kimochii.” As she said the last part her delicate fingers began to trail across my lower body towards my stirring dick. Before she got a chance to grab it, I swiftly unsummoned her.

The other Jenny continued moving her hand down and grabbed my once again hard cock. “Hey, it seems as though a not-so-little someone is in the mood for a second round?” She grinned mischievously at me as she lightly bit into my chest.

“Who could resist you, right? But before anything else, tell me—do you actually remember how you reached down to grab it?”

“Huh? What’s with the weird question, man? With my arm, hands and fingers, of course.” She replied, her fingers gently tickling my dick. Such a snarky non-answer! God, I wanted to put this girl in her place! But more than anything, I needed to figure out how this all worked!

“Yeah, that’s what would be expected, right? But do you actually remember reaching for it?” I pressed her for an answer, staring straight at her.

“Umm... N-no? Maybe? I like... don’t know?” Jenny appeared to be very confused by her own answer.

We laid atop the bed in silence for a while. Her fingers were gently tugging at my manhood, in what felt more like a display of deep affection than begging me for a second go. Laying there, next to my sister, I tried to make sense of it all.

Because I seemed to exists outside of the alternate realities shenanigans created by the Soul Deck, I could remember all of the timelines I had experienced so far, but also the “true timeline” from my perspective in which I swapped between them. Jenny’s Simulacrum only existed in its timeline but because I had just interacted with (well, fucked) both the fake and real Jenny in the same physical space, they were forced to mimic each others movement, because otherwise it wouldn’t make sense from my perspective. That’s why I could be inside either Jenny’s pussy at the same time. That had to be what had just happened, right? But what about now? Their movements seemed almost in sync...

“H-hey, bro. I’m need to ask something that’s been on my mind since I first saw you today...” Jenny suddenly said while her gentle hand still teased my private parts. “Umm... it’s kind of embarrassing... Promise you won’t laugh!” She hesitated, as she paused her hand’s movement. She was clearly very flustered by what she was about to say. “D-do you... mind if I... ummm... call you my onii-chan? When we’re... on the bed?” She finally got out, ending it all with what sounded an embarrassed squeak while her face turned red like a strawberry from shame.

“What the hell, Jenny?!” I got out, my mind was spinning. I thought the idea was that the girl in the card and the Simulacrum would be different? But the small-busted Jenny lying next to me was essentially behaving more and more like my dumb weeb fantasy version of her. What the hell was going on?

“Calm down, bro! I’m just messing with you..!” She did a terrible job of trying to pass off what she had just said as a joke. She looked absolutely heartbroken but she still forced out a strained laughter. She then laid her head to rest against my chest. “I’d love to just lay here forever, just listening to your heartbeat... Why the fuck do I feel like this? A week ago, I didn’t even know it was possible to have feelings like this for someone else.”

“I think you’re just finally being honest with your real feelings, Jenny.” I told her, and she nodded, seeming to take my reply to heart.

We both remained quiet for a while in the luxurious hotel room. Until I finally spoke.

“Hey, I’m sorry, sis. I didn’t mean to be so rude to you, your question just surprised me, that’s all. Naturally I’d be happy to be your... umm... onii-chan, was it?”

When Jenny heard this, she looked up to me, exalted with happiness. She hugged me so tightly that I could barely breathe and then declared in a whisper straight to my ear.

“I love you, Onii-chan.” Both her voice and tone sounded exactly the same as what I had grown used to hearing. And that’s when I lost control of the Soul Deck for the first time since I had acquired it.

The card in which my sister’s soul was trapped suddenly appeared in my hand and began to float out of it. The card hovered in mid-air above the bed while golden cursive writing began to dance across it. Confused, I looked from the card down to my sister resting contently with her head leaning against my chest. She still seemed giddy from what she had said. To me it looked as if Jenny shifted rapidly between the two different versions of herself. Her hair in one moment a mess of twintails, in one moment free and wavy, her body either skinny and lithe or impossibly well-endowed. Jenny, however, seemed absolutely oblivious to what was happening to her.

I looked back up to the floating card above us to see shining golden text across it spell out.

Soul Vessel Successfully Subjugated

A light gasp came from Jenny as her rapid shifting between her two personas came to a halt. Massive amounts of boobs pressed against me as she settled into the superior form I had given her. Additional information began to appear on the card hovering above her. The illustration of a stylized version of my little sister exposing her breasts with a shocked expression changed. The card now displayed the same Jenny, still wearing her mockery of a seifuku, but she was now drawn as if she was hurrying to school in a Japanese neighborhood, running while holding a toast in her mouth. Next, the text on the card partially changed and updated.

“Loving, Energetic and Blood related Little Sister, Jenny Sakamoto” SUPER RARE

• ·Complete soul
• Loves and adores her older brother. Always wants to please him.
• Athletic and energetic
• Great cook
• Loves cosplay, anime and manga.
• This imouto loves when her onii-chan pats her head and praises her.
• [Blank]
• [Blank]

The card floated back to my hand while I tried to grasp what was going on. I decided to do nothing with the blank slots for now and saw how the card shone one more time, writing in gold spelling out a familiar but now slightly different text.

It shall be engraved upon her very soul. Soul Capture Clear! Complete Soul Claimed!

The card settled in my hand and I swiftly willed it to disappear in the same manner that I had usually done. As I did so, my mind was suddenly flooded with new, previously foreign memories.

For as long as I could remember, my biological younger sister, the Japanese girl Jenny Sakamoto, had absolutely adored me. My earliest memories were of her refusing to play with other kids despite our parents’ nagging, content to instead just follow her “onii-chan” around wherever I went. I distinctly remembered how my dad had told me that whenever Jenny had begun to cry as a baby, they simply let me as a little kid hold her and she would instantly calm down. According to my parents, “onii-chan” had been the first word she had ever uttered. I never were sure whether they were joking or not when they told me this.

Naturally, a childhood growing up with Jenny as my constant shadow had been quite weird. When we were both still kids, she had never stopped wanting to play together. She would always try to crawl into my bed to hug me for comfort whenever she had a bad dream. From a very early age she had taken an interest in learning how to cook, since she wanted to be able to prepare food for me. A particularly vivid memory of mine was of how my Japanese little sister had angrily stomped out of the kitchen after pestering our mom about how she wanted to prepare a bento box for me. Mom, a typical American woman, had no idea what a “bento” was, and had told Jenny as much.

As we grew older together, Jenny’s feelings for me evolved accordingly. Her bust had begun to grow early and for a while it seemed as though it would never stop. In high school, her breasts had grown to absolutely gigantic proportions, forcing her to wear mostly custom-order clothes to accommodate for her size. She did not mind one bit though, as she could see what effects her pervy body and lactating breasts had on my horny teenage self. Besides, at home she would gladly strip out of the clothes that restrained her bouncy boobies to offer me a better view. In this new reality I had, naturally, lost my virginity much earlier than before. Heck, there had been weekends when our parents were out of town when teenage me and Jenny had barley done anything else except to fuck like rabbits—my sister always eager to let me do whatever I desired to her.

Jenny’s oversized and bouncy assets did not stop her from excelling at sports, though. She had been the star athlete of our school, and had good grades to boot. Naturally, whenever she played, the audience would double in size, all the extra attendees guys hungry for a show. She was forced by the rest of her team and the coach to wear custom-made sport bras that worked their hardest to keep her bodacious bouncing boobies in place, but nothing they did seemed to be able to contain her fully. Among a school of horny teenagers, Jenny had been considered the absolute peak of a woman and most guy’s ideal girlfriend. No matter what though, my little sister only had eyes for me. I had even gotten beat up by jealous classmates over it a few times...

When I had turned 18, I had acquired a magical card in which Jenny’s body and soul would reside from now on. Jenny had been overjoyed upon the realization that she would never be far away from me, always just a moment from being able to satisfy me. Our parents knew, but aside from them we had kept the fact that I had a magic card that allowed me to summon my sex toy of a little sister an absolute secret. My college life had therefore remained mostly unchanged, though I never really bothered to chase after girls that much. I already had the perfect girl at my beck and call, after all. After a drunken night filled with failed gacha rolls, I had received the rest of the Soul Deck, which I had used for the first time by accident on my bitch of a little sister which had led to me finally ending up in bed with her like this.

I groaned, exasperated. ”None of my new memories made much sense! First of all, how could my now suddenly biological little sister be Japanese when neither I, nor our parents were? Secondly, her body was literally an impossible wet dream that shouldn’t be even remotely possible without extensive plastic surgery, and even then it wouldn’t look half as good. And what the fuck was with the part of me keeping her inside a card several years before I had even heard of Ex Calibre or a magical Soul Deck? Fuck! Wasn’t the entire thing an impossible fucking time loop considering the first woman I still remembered that I had used a card on was Jenny from my original past?” I rubbed my forehead and sighed in frustration while I tried to make sense of it all. I guess just accepting whatever new and impossible scenario the goddamn magic cards threw at me was my new normal.

“Are you daijoubu, Onii-chan?” Jenny asked with a worried voice, in response to my riled huffing and puffing. She leaned her head against me and still seemed totally oblivious to the recent light show above the bed. Her hand still playfully caressed my dick. I needed more of her...

“I’m fine, thanks Jenny.” I replied. After a short hesitation, I continued. “You’re Japanese right? As far as I remember you’re even a Japanese citizen now?”

“Hai~!”

“So uhhh... could you speak some Japanese. Say something really dirty to me.”

On my command, what to me sounded like a native speaker’s Japanese flowed out of my previously Korean little sister’s mouth. As per my request, she spoke in her absolutely most sultry voice. I could understand a few words here and there, but the context of what she was suggesting was clear just from how she said it.

“Damn you sound sexy!” I told her as, my fingers digging into her tight back and buttcheek as a reward. “So, I know that you can speak perfect English too. Hell, you had better grades than me! So... why the crummy weeaboo speech all the time?”

“It’s because Onii-chan finds it both moe and ero to see his Nipponese kawaii imouto speak like a wapanese baka whenever she opens her dumb and silly mouth, ne?” She winked at me, putting her free hand next to her face as if to imitate a cat’s paw scratching an imaginary cat ear. Her hand on my cock grasped me harder; she was hungry for more.

”Fuck yes, I do!” I thought. Jenny’s seduction had made me tire of talking. I rolled over, pinning my little sister under me while she looked up at me with begging eyes, licking her lips. Her perky breasts so big they spilled over her torso, out on the bed sheet under her. I bullied her tits with my dick for a while, while she kept moaning for me to jam myself harder and harder into them. Finally, when I had enough, I entered her absolutely soaked pussy. As I had done countless times before in the current reality we existed in. Neither of us wanted for anything else in that moment.

Jenny was still sleeping next to me, clinging to me tightly, mumbling something in a sleepy Japanese as I untangled myself from her grasp. With a resigned sigh I came to the conclusion that we had made a total mess of the luxury suite’s bedroom. Some poor janitor would have to scrub milk stains off the walls for hours, I guessed. Hopefully, he wouldn’t have to do it for free. Imagine a janitor working for free... Well, if I was getting billed for extra cleaning it was totally worth it, considering the sex I had just had in this room.

I remained for a while by the side of the bed, just admiring my sleeping little sister’s face. She was so freaking adorable. I admired the pitched tent around her torso that her expanded breasts made out of the blanket. And sexy. This was the only version of Jenny now. The only version that had ever existed as far as anyone except for me was concerned. I had essentially fucked the last remnants of my annoying bitch of a little sister out of existence, and replaced her and everybody’s memories of her with a twisted ideal of a little sister of my own making. Man, thinking of it like that was hot! The absurd new memories and my sister’s card changing as it had did make me a bit worried though. Azrael had not informed me of anything like this happening.

I had always preferred to keep a low profile, to draw as little attention as possible. Thanks to my new incomprehensible past, I was almost a local celebrity among my high school classmates due to being that weird guy with an impossibly hot and obsessed little sister. Who was Japanese even though we were supposedly biological siblings, for some reason. Delving more into my new past just caused me further headache. ”Was this some kind of trick Azrael had set up? She was a demon after all, I’d be foolish to trust that a gift from her came without some kind of drawback—” My sister stirred in the bed again, snapping me out of my thoughts. Well, this had happened. And I had to admit that I loved the changes to Jenny’s and mine shared history. Me being in charge of her... I should cherish the moment, but resolved to investigate further when I got a chance.

I washed my face and got dressed, the check out time for the room was fast approaching. I realized that in this reality I had been the one to book the room for us, Jenny spending most of her time sleeping inside a magic card did not leave her much time left for booking hotel rooms. ”Man, dealing with my tangled memory would be confusing!” Thinking about her card, I brought it out and admired the new, more detailed artwork for a while. I then summoned my sister while I was looking at her, still sleeping deeply in the mess of a bed we had made. Instantly the bed was empty and Jenny appeared next to me, energetic and fully “dressed” as always.

“Ohayo, Onii-chan!” She waved exaggeratedly at me even though she was standing next to me. Her naked breasts shook back and forth.

“Good morning, you big goofball.” I replied with a small laugh. “I’m feeling pretty good today. Happy to have you, y’know?”

“Arigato...” She responded and gave me a loving hug, pressing her exposed breasts into me as she wrapped her arms around me. Her face beamed with nothing but happiness at my praise.

Jenny’s reaction and the absolute joy and devotion on display got me thinking about perhaps enjoying the naked tits she pressed into me yet another time. Get your mind out of the gutter. We need to check out, besides you have things to do, remember? An ex-girlfriend that needs to be paid a visit and get some magic attention.

“I know it’s in the middle of the day but I think we should celebrate. How about we grab a nice lunch together? We never really got to go on a date yesterday.” I told my little sister.

“That sounds subarashii... I would love that, Onii-chan. But nani do you mean about deito yesterday?”

“Hmm, never mind that, I guess you never won that tennis tournament anymore, huh? Well, I figure you should wear something more fitting for a date. Right now you’re dressed as if you’re going to school after all.” I said as I brought out her card and began to browse through the outfit options available to me. I finally settled on what clothes to use and my real-life little sister was suddenly wearing them.

Out of her schoolgirl outfit, Jenny now wore a tight silver dress, hanging loosely from straps around her neck. The dress barely covered more than her nipples as it clung lewdly to her perfect breasts. Her waist and legs were totally exposed, her ass and pussy were barely covered by the slinky piece of shiny fabric. She stood on high heels, also of a shiny silver. In addition to the dress and shoes, she wore several pieces of jewelry and her hair was done up in a long ponytail of dark blue hair. As finishing touches, her eye shadow was thick and black and her lips were painted in an inviting red color. My Japanese little sister had in a second been made to look like a first class escort. I fixated on her impossibly inflated boobs. ”No... she looked like a teenager’s sex fantasy of a first class escort.” I thought as my jaw dropped. I just stared at Jenny in admiration.

“Hmm? Are you alright, Onii-chan?” She tilted her head, looking up at me, parting her painted lips.

“Uhhh... yeah...”

“Eh?” She looked down and noticed her glow-up. “Is this dress... made by that famous designer from St. Louis? Sugoi Onii-chan!!” She twirled, giving me a view of her fantastic body while the dress did its best to barely cover her.

“Goddamn...” I finally got out. “You... you need to wear something less revealing! If we go out like this, jealous shrews who see you may die from shock! Let’s... dress you slightly more modestly for now. But we’re definitely changing you back to this after we get home!”

“Ehehe~ Onii-chan’s feeling naughty again! Hentai!”

We left the hotel room together, Jenny clinging to me. She was slightly more modestly dressed.
