Makoto stuttered nervously. "Ahem, we were just playing a game, really. I didn't do anything to her." He looked at Yuna with that flustered gleam. "You have to believe me, Yuna. Say something, too, Mika!"
Yuna wasn't listening. She'd gone from zero to a hundred in about 0.2 seconds. She lunged across the futon, a small, naked, and furious gremlin. "YOU BASTARD!" she shrieked with pure righteous fury. "I KNEW IT! I KNEW YOU COULDN'T BE TRUSTED!"
She tackled him, her small frame surprisingly heavy against his back. Her fists, small but strong, rained down on his shoulders, head, and back. "YOU FORCED HER! YOU TOOK ADVANTAGE OF HER WHILE SHE WAS SLEEPING!"
Mika just lay there with a peaceful smile on her face. She watched the scene unfold with a small, knowing smile. Then, as if she couldn't help herself, she added softly: "He put a baby in me, Yuna-chan." She let out a pathetic whimper. "Against my will."
Yuna's assault redoubled in fury. "YOU WHAT?!" she shrieked in horror. "YOU TRIED TO GET HER PREGNANT?!"
She grabbed a pillow with sharp, jerky movements. "I'M GOING TO FUCKING KILL YOU!" She started beating him with it in a flurry of soft but furious blows. And Mika just watched, a beautiful, triumphant smile spreading across her face.
Makoto groaned as he covered his face and body. "Ouch, that still hurts, you know." He glanced at Mika desperately. "Say something, Mika! And pull her away before she kills me, Ayane."
Mika sighed quietly. The game had gone on long enough. She sat up, movements a bit unsteady, and placed a gentle hand on Yuna's arm. "Yuna-chan," she said softly. "It's okay."
Yuna froze with the pillow held high, chest heaving with protective fury. "Okay?" she repeated dangerously. "He just—"
"He didn't do anything I didn't want him to do," Mika interrupted, her voice growing stronger. She looked at Yuna with mock concern and took a shuddering breath. "It was totally consensual," she whispered, voice breaking artfully. "I begged him."
She looked at him with wide, pleading eyes. Yuna just stared in pure shock. The pillow slowly lowered from her hands. She looked from Mika's tear-streaked, devastated face to Makoto's, confusion and bewilderment in her eyes.
Then from the other side came a sleepy, irritated groan. "Will you all just shut the fuck up?" Ayane's groggy voice complained. She rolled over, pulling the duvet over her head. "Some of us are trying to sleep."
Makoto winked at Yuna playfully. "Come on, it's not like we haven't played that kind of game before." His eyes sparkled with mischief. "You should put more trust in your brother, won't you?"
Yuna stared at him, mouth opening and closing like a fish. The righteous fury and protective rage deflated, replaced by slow, creeping mortification. Her face, pale with rage moments before, exploded in a furious blush.
"You... you..." she sputtered in a strangled hiss. "You were in on it together?"
She looked from his smug grin to Mika's serene smile. Then she let out a sound somewhere between a frustrated scream and a humiliated sob. "I hate you," she wailed childishly. "I hate all of you!"
She threw the pillow at his head with all her might. It bounced harmlessly off his face. Then she burrowed under the covers, becoming a small, furious, embarrassed lump of shame. "Don't talk to me," she muttered grumpily. "I'm never speaking to any of you ever again."
Mika giggled softly, the sound filling the quiet room. "She'll be fine in the morning."
Makoto chuckled. "Hmm, you can't just hit me like that and run away, Yuna." He slid under the cover and started tickling her. "Help me hold her down, Mika. She said she won't be speaking to us."
With a wicked laugh, he dove under the duvet into that warm, dark, intimate world. He found the furious, trembling lump that was Yuna and attacked without mercy. His fingers were spiders of pure evil, dancing over her ribs, armpits, and sides.
The reaction was instantaneous and explosive.
"AHH! NO! STOP IT! GET OFF ME, YOU FAT PERVERTED PIG!" Yuna erupted in high-pitched shrieks and desperate giggles. Her body convulsed, her legs kicking wildly, connecting with him and the mattress in frantic thuds.
"Mika! I need a little help!" he grunted, trying to pin her flailing arms.
Mika didn't hesitate. "Of course," she whispered sweetly in the darkness. With surprising speed and precision, she moved. "She captured Yuna's thrashing ankles with a firm, unyielding grip, effectively neutralizing her main defense.
"Hold still, Yuna-chan," Mika said soothingly. "He's just trying to get you to talk. It's for your own good."
The combined assault was too much. Yuna was completely defeated.
"OKAY! OKAY! I'LL TALK! I SURRENDER!" she wailed, tears of laughter and humiliation streaming down her face. "JUST FUCKING STOP! I'M GOING TO PEE!"
The chaos finally roused the last member of their party. A loud groan came from Mika's other side. Ayane sat up, throwing the covers off violently. Her hair was a glorious, sleep-tousled mess.
"For the love of God," she grumbled thickly. "It's three in the morning. Are you trying to summon a demon, or is this just foreplay?"
Makoto laughed evilly. "Just some usual family and friend bonding, Ayane. You will get used to it!" He kept up his assault with a triumphant grin. "She said she's going to pee. Let's make her, Mika. We can get some blackmail material."
A wicked smile spread across Mika's face. It was terrifying in the dim pre-dawn light. "Excellent idea," she whispered musically. Her free hand joined the assault, her long fingers finding the sensitive arches of Yuna's feet.
Yuna's body convulsed like she'd been struck by lightning. The giggles and shrieks dissolved into a single, high-pitched wail of pure agony.
"NONONONONOSTOPITPLEEEEEASE!" she screeched, voice cracking. "I'M SERIOUS! IT'S HAPPENING! I CAN FEEL IT!" A small, dark, unmistakably wet spot began spreading on the futon beneath her.
"Oh, blackmail material?" Ayane, previously a grumpy lump, was now fully awake. She looked from the spreading wet spot to Yuna's tear-streaked face. A predatory grin spread across her face.
"Hold on," she said conspiratorially. She scrambled for her phone on the floor. "The flash on my camera is pretty good."
The effect was devastating. The triple threat of physical torture, imminent humiliation, and digital evidence was too much for Yuna's tsundere spirit. She broke completely.
"I'M SORRY!" she sobbed brokenly. "I'm sorry I hit you, big bro! I'm sorry I yelled! I'll let Mika be the main wife! Just please, for the love of God, stop before I flood the whole apartment!"
