As Makoto and Ayane reached their seats, they found the scene had changed. Mika was awake, her book back in her lap. Her eyes swept over Ayane's tear-streaked, blissful face, then down to the obvious glistening trail on her thigh. "You paid your debt, darling?" she purred.
Mafuyu was awake too, her eyes wide with concern. "Ayane-chan! Oh my goodness, are you alright? You look…"
Yuna's eyes fluttered open just in time to see Makoto setting Ayane, a disheveled, well-fucked, freshly-creampied mess, into her seat.
"HEYYYY!"
She let out a screech that probably woke the driver in the front car. She stood up, pointing a trembling finger at Ayane's thigh. Her face was a mask of jealousy. "IS THAT…?! DID YOU…?!" She turned her furious glare on Makoto.
"YOU WENT TO THE BATHROOM TO DO THAT?! WITHOUT ME?! I was sleeping right next to you! You traitor! You pervert! You…!"
Makoto ignored the gremlin and whispered into Ayane's ear as he set her down. "I was serious about the marriage, though. Let's have a big one, with all four of you."
Ayane froze as he lowered her, her arms still locked around his neck. The whisper hit her harder than the orgasm did. Her eyes went wide, shimmering with fresh tears, and a smile broke across her face.
"You're crazy," she choked out, sniffing loudly and wiping her nose on her sleeve. "A harem wedding… God, we're gonna look like a cult." She grabbed his face and planted a messy, wet kiss on his lips, completely oblivious to the cum still slowly making its way down her leg.
"I'm in," Ayane beamed. "I'm so in. We're getting married," she blurted out, her voice slicing clean through Yuna's tirade. She leaned back in her seat, spreading her legs slightly in a display of dominance. "He just proposed to all of us, Yuna, Mika, Mafuyu-nee. It's gonna be a big, big wedding."
Absolute silence descended on the two rows. Yuna's mouth hung open, her finger still pointing, but her arm slowly lowered. "M… m… married?" she squeaked.
Mika, who had been watching with amusement, froze. She slowly lowered her book. For the first time, her composure cracked. Her pink eyes widened, and a flush rose to her cheeks. "It's not legal to do that, darling," she whispered, her voice trembling slightly. "But… a social ceremony… a commitment to all of us."
She turned to Makoto, her gaze intense and searching. "You intend to bind yourself to me and the others publicly, darling?"
Mafuyu gasped, her hands flying to her mouth. "M-me too?" she whispered, tears instantly springing to her eyes. "Even someone like me?"
"Yes, you too, Mama-fu," Ayane grinned, wiping her eyes. "He said 'all four of us'. It's a package deal."
Yuna stared at Makoto and Ayane. The jealousy over the quickie in the bathroom was warring with the magnitude of what he'd just said.
Finally, she stomped her foot. "WELL OBVIOUSLY!" she shouted, crossing her arms and sticking her nose in the air, though her face was bright red and her eyes were wet. "I'm the Main Wife! The group wedding was my idea anyway! I've been planning it since I accepted Mika into the harem!"
She grabbed Makoto's arm, hugging it tightly to her chest and burying her face in his sleeve. "But I get to stand in the middle, big bro," she mumbled into the fabric. "And I get the biggest ring."
Mika let out a breath she seemed to have been holding and closed her book with a snap. "I will organize it," she announced, her voice steady but warm. "We will need a secret venue and four custom wedding dresses." She looked at Makoto with a loving smile on her lips. "You have just quadrupled your workload, darling. But I accept."
"I… I can bake the cake!" Mafuyu offered tearfully, reaching across the aisle to squeeze his hand.
"Great," Ayane sighed happily, stretching out her legs and not caring one bit about the mess. "Now that that's settled… can someone hand me a wet wipe? I'm kind of sticky."
"Let's hope Asuka doesn't grow up to be like you, Ayane," Makoto shrugged and facepalmed. He was then caught off guard by Yuna, who suddenly stood and approached Ayane. She had snatched some wet napkins from Mafuyu's bag and stomped over to Ayane's seat.
Despite looking like she was about to strangle the girl, she instead crouched down and started aggressively scrubbing the sticky trail off Ayane's thigh.
"Don't get the wrong idea, cow!" Yuna snapped, her face bright red as she wiped away his seed. "I'm only doing this because you're disgusting! We're in public! If people see you dripping like a leaky faucet, they'll think my brother has bad taste in women!"
She scrubbed harder, making Ayane wince and giggle at the same time.
"And if we're going to have a wedding," Yuna grumbled, tossing the soiled wipe into a trash bag and grabbing a fresh one, "you can't be walking around looking like a used fleshlight. The Second Wife and the… whatever you are… need to have some dignity! For the family image!"
Ayane looked down at Yuna, her expression softening into affection. She reached out and patted Yuna's head. "Aww, look at you, taking care of your sisters. You really are the Main Wife, huh? Thanks, Yuna onee-sama."
Yuna froze at the honorific. Her ears turned scarlet. She slapped Ayane's hand away, but she didn't stop cleaning.
"S-shut up! I'm younger than you! Don't call me that!" she stammered, flustered. She stood up, job finished, and crossed her arms, looking away to hide how pleased she was. "Just don't make a mess again. Or I'll make you wear a diaper next time."
Mika watched the exchange with a satisfied nod. "That's a tsundere Yuna in her natural habitat," she murmured to herself, sounding like she was narrating a nature documentary.
Mafuyu smiled through her tears, clutching her hands to her chest. "We really are a family now," she whispered.
Yuna plopped back down into the seat next to Makoto, huffing and puffing as if she'd just run a marathon. She grabbed his arm again, reclaiming her territory.
"There," she muttered, resting her head on his shoulder and glaring at the others. "Now that the slob is clean, tell me more about the ring. Specifically, how much bigger mine is going to be compared to theirs."
"Finally, my little sister is all grown up. Big brother is so proud of you," Makoto nodded with a fake sob, patting her head. Yuna leaned into his hand as he patted her head, her eyes closing for a split second before her tsundere instincts kicked back in. She swatted his hand away with zero force, then immediately captured it to hold against her cheek instead.
"Don't treat me like a child!" she pouted, though a pleased flush dusted her cheeks. "I'm a grown woman who is about to be a mother and a bride! Show me some respect!"
Makoto chuckled. "I'm gonna get you the one with the biggest diamond, okay, Miss Main Wife? Just give me some time to save enough for four rings."
Yuna practically purred, rubbing her cheek against his palm. "Hmph. As long as you understand the hierarchy, idiot bro," she said, sounding incredibly smug. "Mine has to be the biggest, so everyone knows who runs the house. But…"
She paused, looking down at his hand, her expression softening. She knew how hard he worked to get this job and to provide for them.
"I can wait," she murmured, her voice gentle. "Just don't kill yourself working overtime, okay? I'd rather have you home and healthy with a smaller ring than have a big ring and a dead husband."
"I'm low maintenance, boss!" Ayane chirped from the seat in front, popping her head up again. "You can get me one of those rings from a gacha machine! Or a limited edition anime merch ring! As long as it says 'Mrs. Makoto' on the paperwork, I'm happy. Save the cash for the diapers and for my snacks."
Mika adjusted her sunglasses, pushing them down the bridge of her nose, and looked at him with amusement. "Actually, I've already checked the numbers," she said, her tone relaxed but confident. "If we skip the overpriced designer brands and go to a custom jeweler, which is honestly way classier, we can cut the cost by nearly half. Besides…"
She smirked, a playful glint in her pink eyes. "I made some good money from Mi-sensei consultation sessions and supachat. If you need a loan, darling, I offer excellent rates. Pay by your mouth or your cock, in flexible terms."
Mafuyu smiled warmly from her seat, clutching her blanket. "I don't need anything fancy, Makoto-kun," she whispered. "Just a simple silver band. Or even just a matching string bracelet. As long as it means I'm yours, that's all the treasure I need."
Yuna scowled at her. "Stop trying to score good wife points by being cheap, Mafuyu-nee!" she snapped. Then she looked back at Makoto, her violet eyes serious. "But really, take your time. We aren't going anywhere, Makoto."
