Yuna twin-tails bounced with indignant energy as she walked.
"God, I'm so obvious," she thought, knowing she couldn't hide how hopelessly in love she was.
"I want the strawberry and chocolate one," she called back, making her voice louder and more cheerful than necessary.
"With extra whipped cream. And sprinkles." She glanced over her shoulder with a wicked glint. "And you're paying."
He paid for her crepe, watching as she received the towering creation of sugar and fat.
She'd barely raised it to take her first blissful bite when he leaned in and chomped down on the top, taking a massive, messy mouthful.
Yuna yelped when he attacked her crepe. A glob of whipped cream landed squarely on her nose. "Hey! Get your own, you fat pig!"
The snarl held no real heat. She was too busy trying to lick the cream off her nose, her small pink tongue darting out in a way that managed to be both adorable and unintentionally lewd.
"Let's take a selfie, should we?" His words came out muffled through the food.
She groaned at the sight of his phone. Still, she leaned in anyway, pressing her cheek against his.
A real smile graced her lips for just a second before she forced her features back into their familiar bratty pout.
He snapped a quick, chaotic photo of them together. The picture came out perfect: him grinning like an idiot while she tried to look annoyed with cream on her nose, failing miserably.
He chuckled before sending it to her. "I bet you're gonna use that for showing off."
Her phone buzzed. She checked the screen, and a slow grin spread across her face.
"Showing off?" Her voice turned into an amused purr. She started typing with impressive, terrifying speed.
A moment later, Makoto's phone buzzed with a group chat notification.
[Yuna has created a new group: "Cosplay Project"]
[Yuna has added you] [Yuna has added Mika]
Then she sent the selfie.
Yuna: Look at my pathetic, fat onii-chan. Isn't he cute when he's paying for my food?
Makoto giggled and took a photo of the heavy, overflowing bags of fabric and lace they'd just bought, sending it to the group too.
Another buzz. Mika is typing…
Mika: OMG, you guys are so cute together! And look at all that fabric! Is that for the cosplay party?
Mika: The black lace is really pretty. What are you making with that, Yuna?
Yuna's thumbs flew across the screen. Her grin turned absolutely demonic.
Yuna: The black lace? Oh, that's for my costume. Shizuku-tan. From that anime onii-chan likes so much.
Yuna: He picked it out for me himself. He has… very specific taste. You will be the plain, boring Marin, then.
She looked up at him, triumph sparkling wickedly in her eyes. "Territory marked," she thought with satisfaction.
Mika: Oh! I've seen that one! She's the one with the… the cutouts, right?
Mika: You're going to look amazing in that, Yuna!
Mika: But are you sure you'll be warm enough? It looks a little drafty. ;)
Yuna's eye twitched. That winky-face emoji was a declaration of war.
Yuna: Don't worry. My onii-chan will keep me warm. He's very good at that.
His phone buzzed with a private message from Mika.
Mika: She's not very subtle, is she?
Mika: Don't worry. I can play this game, too.
Makoto quickly fired off a reply to Mika, practically begging.
Makoto: It would help if you don't provoke her too much, lol.
Yuna's eyes narrowed when she caught him typing. Suspicion flickered across her face.
He quickly turned to her. "Feed your big bro one more piece. I'm hungry from carrying all this heavy stuff."
Her expression softened into a smug, satisfied smirk. "Fine. But only because you're a pathetic, helpless slob who can't even feed himself."
She took a bite of her crepe, moving slowly and deliberately. She chewed while keeping her eyes locked on his.
Then she leaned in. Her breath puffed warm and sweet against his cheek.
She didn't feed him with a fork. She fed him with her mouth.
Her lips felt soft, warm, and sticky with cream and chocolate. Her tongue teased his as she transferred the half-chewed bite.
The gesture was messy, intimate, and disgusting. It was also the hottest thing he'd ever experienced.
She pulled back. A thin trail of saliva glistened between them. "There," she purred dangerously. "Happy now?"
"Really happy, indeed," he murmured appreciatively. "I think I prefer you feeding me like this from now on, my little sis."
Yuna's cheeks turned a deep, furious red.
She shoved the rest of the crepe into his hands with a huff. "Feed yourself, you disgusting pig."
The snarl lacked heat. She was too busy trying to hide the small, pleased smile playing at her lips. She turned and stomped off, twin-tails bouncing.
As she walked, she called back, her voice overly loud and cheerful:
"And you're still carrying all the bags, you fucking pervert."
His phone buzzed. A new message in the group chat.
Mika: So, about the cosplay party… I'm free all of next weekend.
Mika: And I was thinking, we could make it a sleepover? That way, we'll have plenty of time to finish the costumes. And… other things. ;)
Yuna was also reading the message.
She stopped dead in her tracks, then turned with a slow, predatory grin spreading across her face.
"A sleepover." She purred the words with amusement. "What a wonderful idea."
He sent a message to the group in silent surrender.
Makoto: Yeah, let's do it on Saturday morning, then.
Then he sent Mika a private message, grinning wickedly.
Makoto: And you should bring some lewd lingerie, too. If you want.
His phone buzzed almost instantly with Mika's private reply.
Instead of text, she'd sent a selfie from a flattering low angle.
Mika appeared to be in her room, holding up two lingerie sets against her body.
One was sweet and frilly, almost bridal-looking white lace. The other was scandalous black straps that barely qualified as clothing.
Her expression showed her wide-eyed, innocent confusion.
Mika: Which one do you think Yuna would hate more?
Before he could even think about replying, a shadow fell over him.
Yuna had stopped walking. She stood blocking his path with crossed arms.
The half-eaten crepe looked like a weapon in her hand. Her narrowed eyes fixed on his phone.
"Who are you texting?" The growl in her voice promised danger.
She stepped closer, her smile becoming pure fury. "Was that Mika?" Saccharine venom dripped from every word. "Did she have another… question about our sleepover?"
She held out her hand, palm up. "Let me see."
Makoto smiled with feigned innocence. "Ehem, it was nothing."
He quickly hid his phone. "She was just asking if I needed any drinks or snacks, but we can buy those ourselves, right?"
Yuna's eyes became slits. Her smile stayed fixed in place while transforming into something sharp and dangerous, razor-blade sharp.
"Oh, is that so?" She hummed with amusement. "How thoughtful of her."
She didn't press. She didn't grab for his phone. She just smiled.
It was the most terrifying thing he'd ever seen.
"You're right," she said, her voice too loud and too cheerful. "We can buy our own snacks." She linked her arm with his, gripping too tightly.
"In fact," she continued, her smile still showing pure fury, "let's go right now." She started walking, swaying her hips excessively.
"And while we're at it," she called back sweetly and dangerously, "we can pick up a few party games."
She turned, wickedness glinting in her eyes. "Like some rope." The growl returned. "And a blindfold, or a collar, and a ball gag too."
She winked slowly and deliberately. "For our… game of Twister, of course."
Makoto sighed wearily. "Umm, that sounds a bit too… hardcore, don't you think? Maybe we should just get some board games and call it a day?" He grabbed the bags and followed her.
Yuna stopped and turned with exaggerated, theatrical disappointment. "Board games?"
Mock sadness dripped from her voice. "But I was so looking forward to a nice, wholesome game of 'Tie Up the Lying, Cheating Onii-chan and See What Mika Does.'"
She gave a dramatic, long-suffering sigh. "But you're right. We should keep it simple."
Her smile turned lethally sweet. "How about we play Truth or Dare?"
She leaned in, dropping her voice to a conspiratorial whisper. "I'm sure Mika has all sorts of interesting truths to share."
"And as for the dares…" Malice glinted in her eyes, making his blood run cold. "…I can think of a few things I'd like to see her do."
She pulled back with a haughty sniff and continued marching toward the store. "And for the record," she called back, again, "we're still getting the collar."
