The living room of the Yuuki household had transformed into a courtroom. The air was thick, heavy, and silent, save for the rhythmic ticking of the wall clock that seemed to echo like a judge's gavel.
Sachie and Mami sat on the floor in seiza, the traditional, leg-numbing kneeling position used for formal apologies and funerals. Their oversized backpacks had been discarded by the door, their hands were folded neatly in their laps, and their heads were bowed low. They looked less like mischievous invaders and more like prisoners of war awaiting sentencing.
Opposite them, sitting on the sofa like a Queen on her throne, was Yuuki Mikan.
She hadn't changed out of her clothes yet. Her arms were crossed over her chest, pushing up the fabric slightly, and her legs were crossed at the knee. Her expression was unreadable, calm, cool, and terrifyingly composed.
And sitting next to her, perched nervously on the edge of the sofa cushion, was Rito.
He had managed to scramble into a shirt, a plain white tee he had grabbed from the laundry basket in a panic. It was slightly wrinkled, and he was still wearing the loose grey sweatpants, but at least he was decent.
Well, mostly decent.
His hair was still messy from Sachie's hands. His skin still held the faint, glistening sheen of sweat that hadn't fully dried. And despite his best efforts to think about baseball, calculus, or the heat death of the universe, the mini-king in his pants hadn't fully gone back to sleep. It was currently trapped behind the waistband of his sweatpants, creating a noticeable, tense ridge in the fabric that Mikan occasionally glanced at with a proprietary smirk.
Rito shifted uncomfortably, the silence gnawing at him. He hated seeing Sachie and Mami looking so dejected. The normal part of him wanted to pat their heads and give them juice. But the honest part, the one who knew the future and understood the gravity of the Harem Plan and thus threw hesitation out of the window, knew that Mikan was right. They couldn't just tackle him whenever they wanted. It was dangerous. For his heart, and for his sanity.
"So," Mikan began, her voice soft but cutting through the room like a razor wire.
Sachie and Mami flinched in unison.
"Let me get this straight," Mikan continued, tapping her finger against her arm. "First you heard the commotion at school, then you confirmed that it was Rito through me. You got jealous because I have something you don't. So, you decided to skip your own homework, lie to your parents about where you were going, and break into my house to... what was the phrase? 'Inspect' my brother?"
Sachie gulped, sweat beading on her forehead. "W-We didn't break in! Onii-san opened the door!"
"And then you tackled him," Mikan countered smoothly. "You pinned him to the floor. You put your hands down his pants without asking. And you were grinding on him like... like little animals in heat."
Mami whimpered, burying her face in her hands. "It... it just happened! He smelled so good! And he was glistening!"
Rito blushed, covering his face with one hand. "Please stop saying glistening..."
Mikan turned to Rito, her eyes softening just a fraction, though her tone remained firm. "And you. You just let them do it."
"I... I tried to stop them!" Rito stammered, his honesty bubbling up despite his embarrassment. "But... they were really strong! And... and they were looking so pleadingly! I couldn't just push them away when they looked like that!"
He lowered his voice, looking at his knees.
"And... I remembered the sleepover. My body... it remembered them. I couldn't help it. I'm a pervert, okay? I liked it."
Sachie and Mami's heads shot up. Hope flared in their eyes.
"See?!" Sachie cried out. "Onii-san liked it!"
"Be quiet," Mikan commanded.
Their hope withered instantly under her gaze.
Mikan stood up. She walked around the coffee table and stood directly in front of her kneeling friends. She looked down at them, her shadow falling over their faces.
"You think this is a game," Mikan said, her voice dropping to a whisper. "You think because you played around with him a little during a sleepover, you understand what it means to be his wife. You think it's just fun and giggles and feeling good."
She placed a hand on her stomach, pressing against the Golden Seal hidden beneath her skirt.
"Being Rito's wife isn't a game," she said, her eyes burning with a sudden, intense fire. "It's heavy and intense. It's accepting that he isn't just yours. It's sharing him with an Alien Princess who can destroy planets. It's sharing him with a Galaxy Idol. It's sharing him with me, his own sister, and many more that may come."
Mikan leaned down, bringing her face level with theirs.
"Do you have any idea what it takes to maintain him?" she asked. "Do you think you can handle the reality of it? Or are you just horny little girls who want to play 'doctor' with a big toy?"
Sachie gritted her teeth. The accusation stung. "We're not just horny! We love him! We've had feelings for him since you spoke of him to us, since we met him the first time!"
"We were just... waiting!" Mami added, tears streaming down her cheeks. "We thought we had time! But then one after another thing came... and now you are already with him! If we don't do something now, we'll never catch up!"
Mami looked at Rito, her eyes pleading.
"We don't want to be side characters, onii-san. We want to be with you. We want the Seal."
Rito felt his heart clench. The sincerity in their voices was palpable. It wasn't just lust, though there was plenty of that.
He looked at Mikan. He didn't say anything, but his eyes pleaded with her. 'They're serious, Mikan. Just like you were.'
Mikan held Rito's gaze for a long moment. She saw the conflict in him. She saw the desire to accept them, to protect them, to love them.
She sighed, standing up straight. The harsh tension in her shoulders relaxed slightly.
"I believe you," Mikan said.
Sachie and Mami gasped. "Really?"
"I believe you think you're ready," Mikan corrected. "But thinking you're ready and actually being ready are two different things."
She walked back to the sofa and sat down next to Rito again. She took his hand, interlacing her fingers with his. The casual intimacy of the gesture, the way their hands fit together perfectly, was a slap in the face to the girls on the floor. It was a display of ownership.
"Rito is kind," Mikan said softly. "He's sweet. He's gentle. But... he's also a beast. You saw him at the sleepover. That wasn't even his full strength. That was him holding back."
Rito choked. "Mikan, don't make me sound like a monster..."
"You are a monster," Mikan said affectionately, squeezing his hand. "A stamina monster. A sex monster. And if these two are going to join the harem... they need to know exactly what they're signing up for."
Mikan looked at Sachie and Mami. A dangerous, calculating glint entered her eyes, the same glint Momo would one day have.
"So," Mikan announced. "I'm going to give you a chance. A test."
"A test?" Sachie blinked. "Like... math?"
"No," Mikan shook her head. "A Test of Resolve."
She pointed at the floor in front of the sofa.
"You say you love him. You say you aren't just horny. You say you want to be wives, not just playmates."
Mikan's lips curled into a smirk.
"Then prove it."
"How?" Mami asked, her voice trembling.
Mikan leaned back, pulling Rito slightly closer to her.
"If you want to be part of this marriage," Mikan said clearly, "you need to see what this marriage actually looks like. Not the sanitized version. Not the 'oops I tripped' version. The real thing."
She turned to Rito.
"Rito," she whispered, her voice dropping to a sultry purr that sent shivers down his spine. "Take off your pants."
Rito froze. "W-What?"
"You heard me," Mikan said, her eyes locking onto his. "Take them off. And the shirt. We're going to show them."
"Show them... what?" Rito asked, though his heart was already hammering a frantic rhythm against his ribs because he knew what she meant.
"We're going to show them the Vow," Mikan said. "We're going to make love right here. In front of them."
The room went dead silent.
Sachie and Mami stopped breathing. Their eyes bulged.
"You..." Sachie whispered. "Here? Now?"
"Yes," Mikan said calmly. "But there are rules."
She pointed a stern finger at the two girls.
"Rule Number One: You must watch. You cannot look away. If you want the Seal, you have to see how it's made. You have to see the intensity, the sweat, the reality of serving him."
"Rule Number Two," Mikan continued, her voice hardening. "You cannot join in. And... you cannot touch yourselves."
Mami squeaked. "W-What?"
"If you masturbate," Mikan said coldly, "you fail. If you touch yourself even once, you prove that you're just horny little girls looking for a quick release. A wife must have self-control. She must respect the sanctity of the act."
She looked at them with a challenge burning in her eyes.
"So? Are you up for it? Can you watch the man you love make love to someone else, and control your own desires? Or will you crumble?"
Rito stared at Mikan. He was blushing so hard he felt lightheaded. The idea was insane. It was immoral. It was taboo on top of taboo.
But...
His honest body surged. The thought of them watching, Sachie's wide eyes, Mami's flushed face, while he fucked Mikan? The thought of displaying his bond, his stamina, his love?
It was incredibly, undeniably turning him on.
Mikan squeezed his hand again, sensing his spike in arousal. She smirked at him.
"Well, Rito?" she whispered. "Are you going to help me test them? Or are you going to deny?"
Rito swallowed hard. He looked at Sachie and Mami, who were staring at him with a mix of terror and desperate anticipation.
He stood up. His hands went to the waistband of his sweatpants.
"I..." Rito's voice shook, but his eyes were determined. "I trust Mikan. If this is what it takes... then I'll do it."
He pushed his sweatpants down.
