Makoto almost screamed. "Me? What? Spare me that thought!" He shook his head.
"I like to watch cute cosplayers, not become one. Nope. Nope! Never." He looked at the three of them. "And I'm a fatso, not muscular like him."
"Oh, don't worry about that," Mika purred softly. She took a delicate sip of her Coke, smiling serenely. "We can get the female version of the costume. The one with the kimono." Her eyes sparkled mischievously. "It's very slimming. And it would be easy to hide those... curves of yours."
"She's right," Ayane chimed in cheerfully. "And we can do your makeup. We're very good at that, remember?" She winked slowly. "We'll make you the most beautiful, terrifying, and fuckable demon lord the world has ever seen."
Yuna grinned ferally, sending a shiver down his spine. "And besides," she growled, "you don't have a choice." She leaned in, her breath hot and smelling of pepperoni. "You're the head of the harem," she whispered. "It's your responsibility to satisfy your wives' fantasies, big bro. And we have a lot of fantasies."
Makoto shook his head. "No! You'd need to get me over my dead body for that." He looked at Mika desperately. "Mika, you're supposed to be the reasonable one, aren't you? You've got to stop her!"
Mika smiled sweetly, though it didn't reach her eyes. She took another bite of pizza. "But Makoto," she said softly, her expression purely reasonable. "I am being reasonable."
She placed her slice down deliberately. "Consider the facts. Fact one, you're now in a relationship with three unhinged cosplayers."
"Fact two, you've helped us with our costumes before."
"And fact three," she added sweetly, "we outnumber you. Three to one."
She leaned forward, eyes sparkling. "Therefore, the most reasonable and logical course of action is to accept your fate and be the best damn Muzan Kibutsuji you can be."
Out of options, he turned to Ayane. "That's nonsense. Ayane, you should help your friend out!"
Ayane nodded solemnly. "She's right. I'm sorry, my friend, but my hands are tied. It's for the good of the harem." She patted his hand in fake sympathy.
Yuna cackled shrilly. "Checkmate, you fat pig. Welcome to the team, we've been expecting you."
Makoto sighed in defeat, realizing his fate was sealed. "Fine. But no photos or pictures. I don't trust any of you not to blackmail me later." He looked at them seriously. "And second, during the con, you three can't say 'no' whenever and wherever I want to fuck. Deal?"
Ayane broke first. A slow, devastating grin spread across her face. "No photos? Okay. I can agree to that."
Her eyes sparkled with mischief, suggesting she had no intention of keeping that promise. "And the second part... No saying 'no'?" She leaned forward, voice dropping to a whisper. "Deal! Absolutely, one hundred percent deal."
Yuna stared at him, her expression a storm of conflicting emotions: fury, disgust... But underneath, genuine excitement flickered. "You disgusting, perverted pig," she snarled. "You think you can just make rules like that?"
She took a vicious bite of pizza, chewing angrily. "Fine," she muttered grudgingly. "Deal. But don't come crying when you get arrested for public indecency. And I won't bail you out."
Finally, all eyes turned to Mika. She remained serene. She took a final sip of Coke and placed the can down with a soft click. "No photos. And a binding rule that we must submit to you, at any time, in any place, for the entire convention."
She looked up at him with wide, innocent eyes shining with feverish devotion. "Makoto," she whispered, "that's the best deal anyone has ever offered me in my entire life."
Makoto shrugged casually as he gave up. "Shit, you three are nuts, I swear!" But he smiled fondly at them. "But don't complain when your cunts are being pumped full of my cum in those costumes."
He looked away, unable to hide his recovered, throbbing erection.
Ayane put her pizza down, all pretense of eating forgotten. "Complain?" she purred. "Honey, that's not a threat. That's the entire fucking point." Her eyes dropped to his lap, and her grin widened. "And look at that. Little Muzan is already eager to get started."
Mika remained silent. She just looked at him, expression unreadable. She slowly licked a stray drop of tomato sauce from her thumb. "A promise, then," she whispered reverently, cutting through the others' noise. "You promise you'll pump us full."
She looked down at his lap with a serene smile. "Good. I've always wanted to be a good, obedient demon who gets bred by her master."
"Hah! Look at you!" Yuna snorted, cheeks flushed deep red. "You're the one who's already hard! You said all that tough-guy shit, but you're just a big pervert!" She threw a pizza crust at him. It bounced harmlessly off his chest. "And I won't be complaining. I'll be making you complain when I've sucked you so dry you can't even walk."
Makoto sighed wearily. "This wasn't what I had in mind when I imagined having a harem." He coughed, clearing his throat. "Fine. We can have one anime marathon, then we'll go to sleep before I drive you all to college tomorrow."
A collective sigh of disappointment rippled through the room. But they relented for now.
"Fine," Yuna grumbled, plopping back on the couch and grabbing the remote. "But I'm picking the anime. And no romance or school-life shit!" she added.
"That makes sense," Mika agreed with a polite smile. But her eyes sparkled with unspoken promises. She gracefully took her spot beside him.
"Just a quiet night in with my favorite people," Ayane said too sweetly. She flopped down on his other side, her head landing in his lap with a contented thud.
Makoto patted his lap and smiled. "Come and rest on my lap, too, Yuna. There's still some space." His eyes had that wicked gleam she knew so well. "And don't pick something with more than one season."
Yuna glanced at Ayane's smug face, already comfortable in his lap, then back at his outstretched hand. Part of her wanted to refuse, but the desire to be closer to him won out easily.
She let out a sigh that was supposed to sound like she was making a huge sacrifice. "It's not because I want to," she muttered as she scrambled into the remaining space on his lap and burrowed her face into his stomach. "It's just easier to watch the screen from here."
Mika giggled softly from where she was snuggled against his side. "Of course, Yuna-chan."
"And I'm picking Puella Magi Madoka Magica," Yuna declared, her voice muffled but triumphant against his belly. "It's only twelve episodes. And it is a... cute magical girl show, suits us very well."
