My Little Stepsister is Addicted to Gacha Games-131 – Eyes Of The Storm
Back home, half an hour ago.
As the front door slammed shut, Makoto's footsteps faded down the stairs, leaving a sudden, heavy silence in their wake. The absence of his chaotic energy was palpable. For a moment, the three girls were just three individuals in a messy living room.
Then, a low, rumbling growl emanated from the sewing machine.
"Fucking finally," Yuna muttered. She was already hunched over the machine, her foot pressing the pedal with renewed vigor. "Now we can actually get some work done without the damn pervert distracting us."
Ayane let out a long, lazy stretch, a picture of post-massage bliss. "Speak for yourself," she purred. She rolled off the couch and sauntered over to the pile of fabric, a slow grin spreading across her face. "I found his distractions very motivating."
Mika, who had been quietly sweeping the floor, set the broom against the wall. She walked over to the table and picked up her discarded clothes with a serene smile. "He has a lot of energy," she said softly. "It's important that we help him manage it properly."
An unspoken understanding passed between the three of them. The hierarchy, the competition, the drama... it was all still there, humming beneath the surface. But for now, there was a truce.
They were now a team. A very dysfunctional, very horny, but effective team. And they had a mission: to create the most breathtaking costumes for the world to witness. No, maybe just for a certain pig to witness.
The next hour was a blur of focused creative energy. Perhaps Yuna was right about how productive they would be without Makoto's intervention.
Ayane, surprisingly, proved to be an adept assistant, pinning and cutting with newfound precision. Mika was a silent, graceful whirlwind of efficiency, her hands a blur as she worked on the intricate details of her own Nezuko's obi. And Yuna was the queen, the general, the undisputed ruler of her fabric-and-thread kingdom.
As Yuna finished a hard sewing and decided to take a short break, she pulled out her phone. Her thumbs flew across the screen. Then, a slow, wicked grin spread across her face.
[Yuna has added Ayane]
[Yuna has changed the group name to: "Yuna and the Backups"]
Ayane's phone buzzed. She glanced at the screen, and a delighted grin spread across her face. "Backups?" she purred, amused. "Is that our official name now? It has a nice ring to it."
Mika, from her position by the dustpan, just smiled. "It's just a temporary title," she said quietly.
Then Yuna started typing. Her thumbs flew across the screen with impressive speed.
Yuna
: Hey, fat pig. Forgot to tell you, I just got my period. So buy me two boxes of menstrual pads. The ones with wings I usually use. And the extra-long, overnight ones.
Yuna
: And don't you dare get the cheap, store-brand crap.
The message was a masterpiece of tsundere communication. She was showing off, broadcasting their shared history, a clear message to the other two:
"See, he was mine first."
It was also a demand, a test of his devotion, and, most importantly, a public declaration of their intimacy.
"He buys me sanitary pads,"
it screamed.
"See. We're that close."
Ayane's eyebrows shot up. "Oh?" she said with a wicked glint. "Marking your territory again, are we, main wife?"
Yuna shrugged like it was nothing. "He's used to it. He's been buying them for me since I was thirteen. He doesn't even get embarrassed anymore." She continued, her voice softer this time. "He's a good... big brother. He will make a good husband someday, too."
The last sentence was a direct hit, a perfectly aimed shot. The casual intimacy of the request, their shared history... it was a power move far more devastating than any lewd photo.
"Speaking of... big brother," Ayane said, leaning back against the couch and crossing her legs. "How exactly did that happen? The whole step-sibling thing. I know you guys aren't blood-related, but how did his dad and your mom meet?"
Yuna didn't look up from her phone, but her shoulders went stiff. "Eight years ago, my mom and his dad met at a business conference. They quickly got married six months later."
She picked up a piece of chalk and started marking a hemline with aggressive strokes. "And then they basically vanished: International business trips, long-term assignments. We barely see them, maybe once or twice a year."
She stopped, the chalk hovering over the fabric. "So it's just been us. Since we were kids, we had to take care of ourselves."
Something vulnerable flickered across her face before she buried it under a scowl. "Well, us and Mafuyu-nee. Time to time, she'd come over and make sure we didn't burn the house down or starve to death. She was nice, annoyingly nice."
"Mafuyu..." Mika tested the name, her expression thoughtful. "The woman back then at the family restaurant?"
"Yeah, her," Yuna muttered. "She treated us like we were her own kids or something."
"I see," Mika murmured, her eyes gleaming with calm, analytical light. "Two lonely children, left alone in a big house, relying only on each other for emotional and physical support. It explains your relationship." She tilted her head, a small, sharp smile playing on her lips. "And the lack of boundaries."
Yuna glared back at her. "We have boundaries!"
"Do you?" Mika asked softly. "Because I seem to recall a story. Didn't you sell him your used underwear at a massage parlor? Do normal step-siblings do that?"
Yuna turned crimson. She spluttered, waving her chalk threateningly. "It was just a transaction! I needed money for the Ganyu banner! And he was being a pervert! It was simply supply and demand!"
"Supply and demand," Ayane repeated, cackling. "Oh my god, you really are a hustler. How much did he pay?"
"20,000 yen (~130USD) !" Yuna yelled. "And I got a five-star weapon out of it, so shut up!"
"Twenty thousand..." Mika mused, her smile widening. "So that is the price of the Main Wife's dignity. Good to know."
Before Yuna could launch herself across the room, her phone buzzed. She glanced at it, then opened the group chat.
A notification popped up on everyone's screens.
Mika
: Oh, what a coincidence. I think my period is starting today, too. Could you get me the same kind, darling? I'm not as picky.
Mika
: By the way, it also means that Yuna and I will both be ovulating in about three weeks, at the same time.
It was Mika's perfect counter-move. A subtle shift in the power dynamic.
"Now Makoto buys me pads, too. We're that close, also."
The timing was too perfect. Ayane raised an eyebrow. "You know, with all the unprotected sex we've been having, I'm surprised any of you are still getting your periods at all." She paused, chuckling. "You should probably stock up on some pregnancy tests while you're at it. Just in case." She let the sentence hang in the air.
Yuna rolled her eyes. "Don't be an idiot," she said. "It's not that easy to get pregnant. The chances are, like, super low." But there was a flicker of something in her eyes, just a small doubt.
Mika, on the other hand, just smiled. "I think it would be lovely," she said softly. She looked at her own flat stomach with a thoughtful expression. "It would be a wonderful addition to our family, a very efficient way to bind him."
"I would name her Aiko if it's a girl." She looked up from her phone, her eyes sparkling. "And for the record," she said, her voice calm and sweet. "Unlike your parents, I think I'd make a wonderful and caring mother."
