"Brother~ come sit here!" Aki patted the seat beside her with her chosen food—somehow, she rejected going somewhere nice in my car and said the burger place near the university was the best.
Yet, for some reason, before we could leave, she insisted on going to her dormitory to change, now wearing a cute black dress with white stockings up to her thighs and cute Alice shoes.
I didn't know how to speak to Elizabeth.
Do I speak as Aki's brother or the guy that fucked her all night... At moments like these, my social issues were quite the problem.
Since Aki is nothing like I thought in the past, let's give her the chance she deserved from the beginning without my stupid negative thoughts and bullshit, Elizabeth can wait, and this doesn't change our deal.
If Aki wants to know about us, I can be honest and leave out the sex part—no sister wants to hear about her brother banging another woman, especially when it's her friend or tutor.
[...]
"Hehe~ brother, do you like chicken burgers?" My adorable sister flashed her smile at me, leaning forward as she took a bite from her burger, her soft black hair swaying as she chewed quickly before swallowing. "I thought you would prefer a double beef burger instead."
"Honestly, I am not picky, so whatever you want is fine." I didn't mind; little did she know when I was at my worst, there were expired microwave meals for me for a week...
She and Mother got the good stuff with 2-3 days remaining.
The meal was nice and greasy, but the taste of melted cheese and fried chicken made me feel alive after the long night of sex, drinking and a few hours of sleep.
Not to mention the damn exhausting talk with Eternia... God let me go back to the dungeon and kill Ratmen. I'd rather fight for my life than deal with emotions right now...
Suddenly my little sister leaned close to my ear, cupping her lips to block Elizabeth's view.
Her breath was warm, and her greasy lips touched my ear—it was wrong, but I felt myself getting aroused, but she kept doing it, and then she whispered, "It was so cool when you paid for Elizabeth's food without even looking..."
She looked at me with her huge eyes, blinking them with concern as she continued. "Brother, are you trying to make her boyfriend a cuckold? That's not good, brother... If you need to... I can be your partner!"
[!!!]
[(WINCEST!)]
I won't lie because her words caused my heart to skip a beat—this girl doesn't understand the dirty thoughts I hold towards her, accidentally seeing her masturbating... her naked in the shower...
Now, she plays with fire by saying such a risky thing.
So I must teach her a lesson so she won't say stupid things anymore, even if she hates me and stops speaking to me for a long time. It will stop her from ruining her future.
My hand slipped under the table while she moved away to take a bite of her burger, resting on her soft thigh—thankfully, her jeans were gone now as I placed my hand on her inner thigh, feeling her body tremble before she looked at me with those huge eyes in shock.
Silly sister... I am this kind of man; don't tease me in the future, or you will be punished.
[(Oh no... He doesn't know...)]
[(*Crunch**nom*)]
Elizabeth suddenly spoke, her soft, alluring lips eating a bite of her chicken wrap before smiling at me—somehow, whenever I am around this blonde girl, I become more lustful. Is it the reaction from last night?
"So what do you plan to do for the rest of the day, Rai? We will study after this and then maybe hit the gym together."
"Hmmm, the gym?" I asked, looking at her chest, and a smile came to my lips, imagining her in tight-fitting clothes... Erotic.
"Fufu, brother, don't you ha...have work? Mmmm...." Aki said tremblingly as my fingers moved closer to her most precious place.
Or maybe this is the me who isn't held down by my negative feelings? As my fingers slid naturally between my lovely sister's thighs, separating them with ease... No? Why has Aki spread her legs willingly... Is she scared I might get mad?
"N...no work! Brother won't do...work when he...wants to. So...so...do you think about going to the gym? Like...you know..."
"Eh? What's wrong with your stutter, Aki? Oh~ I know being with your brother is so rare. You are shy. Fufu is such a cute girl." The support from Elizabeth was welcomed, even if she had no idea—my fingers were now teasing my little sister's crotch to teach her a lesson.
[(What lesson? How to let your brother make you climax in a burger joint?)]
"I will go home and shower first. Then we can go. You don't have classes?" I asked casually while sliding my hand up the inside of her thigh.
Reaching towards her panties, peeling them to the side slowly, hoping she pushed me away or closed her legs—my fingers were met by moist warmth as I felt her body suddenly shudder before her hand slipped under the table.
Ah, she's going to stop me... Finally, she's learned --- Before I could stop my sentence...
My index and middle fingers were suddenly wrapped in something warm, sticky and wet that felt alive and wriggling around them, tightening and undulating... My fingers were inside the pussy of my little sister... and her hand was the one pushing them inside...
I seem to have made a mistake...
The blushing face and lustful eyes made something clear to the idiot me with zero romantic experience... Maybe... she was just like me, masturbating and overdoing things with me that night...
[(Oh!? He's beginning to believe!)]
Is that why she was so hysterical!?
[-fog horn sounds-]
[We have a fucking winner, folks!]
I heard the fairy's scolding voice for the first time in a while... as my sister's hand continued to pleasure herself with my fingers, wanting to help her, I started to hook my fingers, searching for her pleasant spots, causing the cute girl to lift her ass off the seat when I did, the oblivious Elizabeth just ate her ice cream sundae quietly.
[....]
[Rai, there was some wise advice an old man once gave...]
"Haa....brother....mmm...it's like a dream...Haa...." My little sister became a seductive minx as she leaned against my side, her lips whispering into my ears, blowing hot air down my neck as her insides became warmer, clammier and started to tighten with more force, with a slimy feeling bubbling around my fingers.
Aki's hand moved with much vigour now, sliding back and forth along the length of my two fingers, fucking my hand, biting her lower lips. I tried to endure the amazing sensation of my little sister's insides while my cock felt like it would tear through my pants, becoming painfully hard.
I felt too self-conscious looking around, but nobody seemed to notice I was fingering my little sister!?
[(I can't let you ruin you life...)]
[Those words were, "Never put your dick in a crazy..."]
Her words didn't make much sense as the inside of Aki's tunnel began to confuse and paste, her hips floating off the chair as she arched her back, gasping loudly. Still, nobody noticed as my sister began to climax!?
"Haa... Haa...Haa... I'm cumming...I'm cumming! Brother, please... help meee...!"
Aki pushed my fingers deeper, causing her body to stiffen as her mouth opened. She panted for air, her soft tits smooshing against my side as I kept my fingers hooked within her, making her moan and cry out with my finger's rapid movement until her body shook and her juices covered my fingers, dripping to the ground, a puddle forming at our feet.
Aki let out a cute whimper and sighed, her body still trembling as I slowly slid my fingers from her twitching tunnel, bringing them to my lips to taste her sweet juices, the salty and sour taste reminding me of how her room smelt that night a year ago.
"What happened?" Elizabeth asked me as I licked my fingers clean while my sister leaned heavily against my arm.
"Ah, nothing, just some sour cream on my fingers from the burger," I said, sucking my little sister's taste while Aki stroked my thigh, typing something on her phone's display...
She then showed it to me under the table, causing my heart to almost stop...
[!!!!]
[Real-life sexual blackmail!]
I only want to know when my little sister became such an evil little imp!?
