"You must be Yuki-kun's little sister, right?"
"Hello, I'm Kitagawa Marin, your brother's classmate and friend! Nice to meet you."
Using her naturally sociable skills, Marin greeted Kotori with affinity.
"Hello, I'm Kotori Itsuka. Nice to meet you too."
Kotori gave a slight bow in polite response.
"Kotori-chan, right? You're so cute!"
Marin, being her cheerful and outgoing self, immediately addressed her by name.
Seeing how familiar Marin acted, Kotori couldn't help but show a flicker of surprise. But it didn't really matter; since she was her brother's friend, it was fine to let her use her name.
"Thank you. You're very pretty too, Kitagawa-san," Kotori replied with a smile.
"Hehe, thank you, Kotori-chan! But just call me Marin! Using surnames feels too formal."
"Alright, Marin-san."
Kotori nodded lightly.
Hearing Yuki's little sister call her by her first name, shortening the distance between them, Marin inwardly cheered. This meant she was already on good terms with Yuki's sister.
At that moment, Origami suddenly looked at Kotori and asked, "Kotori, am I not pretty?"
Hearing this, Kotori glanced at Origami but didn't answer.
"Let's go, Onii-chan."
She then took Yuki's hand and started heading home.
Ignored, Origami showed no anger and calmly followed along.
Marin quietly followed as well, looking curiously at Origami and Kotori. Judging from their earlier reactions, it seemed like the two already knew each other!
That's what Marin guessed internally.
Of course, she kept this question to herself and didn't ask.
For the rest of the walk, Marin fully utilized her social talents, chatting happily with Kotori and Yuki. Occasionally, Origami would chime in, but most of her comments involved innuendo, which gave Marin a whole new perspective on Origami.
She never imagined that this usually quiet, icy beauty from class had such a side to her. Hearing her casually drop a stream of bleep-worthy remarks was quite an eye-opener.
But what puzzled Marin even more was the matter of Yuki and Kotori's surnames.
It was quite obvious: Kotori's surname was Itsuka, while Yuki's was Rin. This didn't seem like the situation for biological siblings.
"Um... Kotori-chan and Yuki-kun, are you two not biological siblings?"
Marin seized the opportunity to ask.
"Mhm, we're not."
Yuki nodded with a smile.
"Huh? So... are you cousins?"
Marin thought she understood.
"Nope, neither biological siblings nor cousins. You could say my parents forcibly gave me a brother. We don't share any direct or indirect blood relation."
Kotori answered flatly.
"Forcibly? Kotori, did you forget it was you who told Uncle and Auntie you wanted an older brother?"
Hearing Kotori's words, Yuki couldn't help but tease her.
Kotori's face instantly flushed red, and she hurriedly explained, "I was just young and ignorant back then! Looking back now, I don't need any big brother. Besides... what kind of brother would... with his little sister..."
Her voice grew softer towards the end, the last sentence mumbled out. The more she thought about it, the redder her face became, recalling what happened the night before last. What kind of sibling relationship was that?!
Marin watched, feeling a bit strange. She felt there was still something puzzling here, but the thought only flashed through her mind. For now, she understood the relationship between Yuki and Kotori.
"So... you're adopted siblings?"
After some thought, Marin found the appropriate term.
"Well, you could say that."
Kotori nodded.
The four of them walked for about ten more minutes before Marin had to part ways with Yuki. Though the first part of the journey was along the same route, their homes were in different directions later on, so they naturally separated at a fork in the road.
After saying goodbye to Marin, Yuki took Origami and Kotori back to the villa.
Entering the house, Yuki noticed Mio didn't come out to greet them today; she was still busy in the kitchen.
Taking off his shoes and changing into slippers, Yuki headed to the living room and saw the graceful figure bustling by the kitchen.
Mio seemed to sense Yuki's return and immediately turned around. Her fair, beautiful face broke into a gentle smile.
"Welcome back, Yuki."
"Mhm, I'm home."
Yuki nodded and went to the kitchen. Mio was wearing a red apron. Even under the apron, her perfect figure still showed its curves. The apron didn't cover the skin on her back, her white-jade-like skin was exposed to the air.
"Dinner will take a little while. If you're hungry, you can have some snacks first."
Mio gently touched Yuki's face, her tender expression radiating a wifely charm.
"No need. Compared to snacks, I find Mio-nee much more delicious."
Yuki smiled knowingly, wrapping his arms around Mio instead.
"No way! You're so annoying~~~"
"Not now! I still have to cook!"
Feeling something rock-solid against her, Mio's heart fluttered wildly as she protested nervously.
"It's fine. You focus on cooking; I'll focus on... my own meal."
Yuki's hands moved up Mio's sides, fingers feeling the soft curve of her waist under the red apron. Her skin was warm and smooth under his touch. She stirred the pot on the stove, trying to stay calm, but her breath caught as he pushed his hips forward. His hard cock pressed against her ass through her short skirt.
"Yuki, really... They will hear us," Mio said, her voice a mix of complaint and excitement. Her blue eyes looked to the side, seeing him in the kitchen window, but she didn't move away. Her free hand held the counter tight.
He laughed softly in her ear, lips touching the side as he nuzzled her neck. She smelled like vanilla and flowers from her white hair.
"Let them then. You've tease me with this apron, now suffer the consequence" His hands went higher, cupping her big breasts through her thin top. They fit his hands well, full and firm, nipples getting hard as he squeezed.
Mio gasped, the spoon hitting the pot. "Teasing? I was just cooking." But her body showed she liked it, leaning back into him, her long hair falling over his arm. Yuki pulled her top up, showing her bare breasts to the kitchen air.
No bra—her breasts bounced free, milky white skin under the light. He leaned down, taking one hard pink nipple in his mouth, sucking strong while his tongue went around it. Mio moaned, her calm breaking as he switched to the other breast, sucking hard to make her legs weak. A sweet taste came from her excitement, her hands grabbing his shoulders.
He let go of her nipple with a wet sound, stood up, and turned her to face him. Mio's blue eyes were foggy with want, cheeks red, hair a bit messy. He pressed his mouth to hers in a hot kiss, tongues twisting as she opened up. Her lips were soft, soon wet with spit. Yuki's hands went over her back, pulling her close so her bare breasts pressed on his chest. She whimpered in the kiss, fingers in his black hair.
The kiss got deeper, hot and fast, breaths heavy until he stopped, biting down her neck. Mio breathed hard, her calm turning to need. Yuki got on his knees, looking at her hips. He lifted her short skirt, hooked fingers in her white lace panties, and pulled them down. She stepped out, her trimmed white hair and wet pussy showing.
"Spread your legs," he said, voice rough. She did, opening her thighs as he leaned in, tongue licking flat on her clit then lower. He licked her folds all over, tasting the sour wetness on his mouth, then pushed his tongue inside her warm hole. Mio cried out, one hand in his hair, the other on the counter. He sucked her clit, then licked deep into her pussy, drinking all her juices as they came out. Her wetness ran down his chin, sweet and strong, as he hummed, making her hips shake.
Her moans filled the kitchen, high and wanting. "Yuki... yes, there... I'm going to-" She stopped with a gasp as she came, pussy squeezing his mouth, giving more wetness. He drank it all, licking until she shook and pulled him up, legs wobbly.
Yuki stood, took off his pants fast, his cock jumping out—thick, veined, hard, pre-cum at the tip. Their blue eyes meeting with hunger. Mio's hand took his cock, stroking hard as she knelt on the floor, her calm face now full of want.
She put him in her mouth slow, lips stretching around him, tongue on the head tasting his salt. Yuki groaned, hand in her white hair, pushing her deeper. Mio moved her head, sucking tight, taking more until her nose hit his belly. She took him all in her throat easy, throat loose around him, eyes tearing but looking up.
"Fuck, Mio-nee, your mouth feels so good," he breathed, hips moving to fuck her mouth slow at first. But he wanted more; he held her hair tight, thrusting harder, balls hitting her chin. Spit dripped from her lips with pre-cum, her big breasts moving. Mio gagged a little but hummed to keep going, hands on his legs.
He pulled out fast, lifted her up, and bent her over the counter. Her ass was perfect—round and tight—as he lined up his cock with her wet hole. One push went all in, her pussy tight around him, hot and soft. Mio yelped, then moaned loud, pushing back.
Yuki fucked her hard, hands on her hips, skin smacking loud in the kitchen. Her long hair swung with each push, breasts flat on the counter.
"Harder... Yuki, fuck me harder," she said, voice breaking from her usual calm to a real beg.
He did, one hand rubbing her clit, the other in her hair pulling her head back. Her blue eyes rolled back in pleasure, mouth open without sound as another orgasm came. The way hit deep, cock rubbing her inside, stretching her.
"Cum inside me," Mio gasped, body tight. Yuki's thrusts got wild, balls pulling up as he pushed in last. He came with a deep groan, hot cum shooting in her pussy in big bursts, leaking down her legs. She broke around him, pussy squeezing every bit, her body shaking in joy.
They stayed tangled together, breath still uneven, heat slow to fade. He hadn't even pulled away yet when Mio shifted against him, her face flushed, eyes soft and content. She kissed him lazily, unhurried, smiling into his mouth.
Somewhere behind them, a quiet step paused.
When Origami came to the living room and saw the scene in the kitchen, she decisively chose to join in without any hesitation.
Kotori was the same, though not as decisive as Origami. When she entered and saw this, she initially scolded them. But seeing the three of them unmoved, she chose to join in the mischief, joining them in their collusive activities.
Two hours passed.
When Yuki returned to his room, he realized it was already around 8 PM. He couldn't help but chuckle wryly.
This dinner had taken quite a while.
From the kitchen to the dining table, who knows how many "dishes" they had actually consumed. But one thing was certain: Mio and the others had eaten quite a lot, and it was particularly nutritious stuff.
Just as Yuki was about to pick up his computer to check his social media accounts as usual, his phone chimed with a message.
Opening it, Yuki saw it was from a contact saved as a "Private Research Institute." The message was brief, just a few words:
[The Angel says she misses you.]
Seeing this, Yuki put the computer back on the desk.
He then snapped his fingers lightly. A starry portal flashed for a second, and Yuki vanished from the room.
