Outside the window, a steady drizzle pattered against the glass.
The crisp sound of raindrops was perfect for sleeping, working, or reading.
Especially in a study like this, bookshelves packed with volumes giving off that faint plant-fiber-and-ink scent that easily drew people into reading.
Influenced by the atmosphere,
Sasaki picked a biography, sat at the desk, and started reading.
In the quiet, undisturbed space, it was easy to lose yourself in something.
He didn't even hear Ayumi-nee calling him for breakfast from outside the room.
Only when a soft touch brushed his cheek did he snap out of it like waking from a dream.
Pulling his eyes away from the text that looked even darker under the gloomy window light, Sasaki turned his head and met the girl's smiling face as she bent down to look at him.
Her beautiful, mature features hadn't changed; still lovely, still wearing the same clothes from yesterday.
Yet somehow, Sasaki felt Ayumi-nee looked even prettier now.
After staring carefully, he noticed the light flush on her vivid, alluring face, paired with that subtly seductive smile and the way she bent at the waist with hands on her knees; her whole presence gave off an irresistible, captivating aura.
Less of a lively young girl's wildness, more of a mature woman's gentle elegance.
Sasaki was about to compliment her, tell her she looked even more beautiful now.
But Ayumi wrapped her arms around his head and roughly pulled him into her chest:
"Ehh~ I didn't know you had a literary side too. Big sis likes you even more now."
...The elegant act lasted less than three seconds before her true self came out... everything just now was his imagination.
Even if she became a full wife someday, Ayumi-nee would never change.
Still... feeling the warm, soft breasts rubbing against his face, Sasaki suddenly thought, maybe this was fine.
If she suddenly turned completely proper and reserved, he might actually feel uncomfortable.
As he thought about it, he reached around her supple, snake-like waist, sliding his hands down the silky A-line skirt, and pulled his big sister, now completely his, into his lap.
Muffled in the overflowing softness and warmth,
Sasaki nuzzled gently and asked in a muffled voice:
"Still hurt from last night?"
Compared to his rough first time with Otome, he had plenty of experience now.
So, he was quite confident he had given her the best sex experience he could give.
Although she was unable to endure it in the end, the overall experience should be five stars.
Still, asking to show concern was still best.
Hearing her man's worry,
Ayumi lifted her eyes, corners of her mouth curving into a smile, then smacked his back playfully.
"Now you're asking? Last night, when you kept telling me to lift my ass higher, why didn't you ask then?
You treated me like play-dough, kneading and squishing... now you're acting all concerned. Fake~"
"Uh..."
No...
'Are we thinking about the same things?'
Because Sasaki remembered,
Except for the very beginning when he lost control because of just how fucking irresistible she looked, he never used too much force when pounding her.
After all, sex was about mutual pleasure and deepening feelings.
One-sided pleasure was too selfish... so everything last night was with Ayumi-nee's consent.
It was she who kept begging "deeper" and "more" anyway.
Now she was flipping the script and blaming him entirely.
Thinking about it, Sasaki teased back with a laugh. "Then next time I won't move at all. Ayumi-nee can do whatever she wants then."
No way.
That would only work at the start, making her feel like she was the one taking the lead, but later it would be too tiring...
Just thinking about it, being so tired, unable to lift an inch,
Ayumi hugged his head tighter against her chest, fingers idly twirling his hair, a blush spreading across her fair, tender cheeks:
"Jeez... I just said you were too wild.
I didn't say I disliked it. If you just lie there and do nothing, don't you think that's way too irresponsible?"
As if to hide her embarrassment, the girl tightened her arms around his neck. "Mou~ I don't care.
Next time, you'll still be the one taking the lead. And the same rhythm as last night, I don't mind at all."
"Mm... okay~."
Hearing her direct words, Sasaki patted the swell under her A-line skirt, signaling her to ease up, and as she relaxed her arms, pulled his head free.
After all, this was Ayumi-nee's unique way of being affectionate.
Although a little suffocating, it was mostly comfortable, so Sasaki didn't complain.
Instead, he asked:
"How did the talk with Sister Akane go?"
Hearing him bring up serious business, the playful smile on Ayumi's face gradually faded, and she answered earnestly:
"I chatted with Akane a little earlier. Her thoughts are pretty much what we guessed."
"But there's an agreement between them, only after marriage can they give themselves to each other."
"Normally, they have almost no intimate contact, so last night Akane asked you, 'if she were your girlfriend, what would you do to her'. She also feels Sawamura is being overly polite."
"I see."
Sasaki nodded and smiled.
"No intimacy because there's no real desire in his heart... and the 'only after marriage' rule... he definitely hasn't given Akane a specific wedding date, right?"
"Mm, he never told her a time. Just said 'after we stabilize things'..."
Knowing Akane's exact situation, Sasaki asked:
"With Sawamura ignoring her like this... Sister Akane probably already agreed to your suggestion to 'help her increase her attractiveness', right?"
Her boyfriend not being close to her... plus the shameless display from him and her sister Ayumi... no matter what Sister Akane was thinking, she wouldn't refuse her big sister's help in her time of need.
And sure enough, Ayumi nodded. "Yeah, Akane already agreed. When she's free, I'll teach her some makeup tips, how to dress better... and, um, some special things too."
"During our chats, I'll steer the conversation toward you two... Sawamura will be nervous for a while."
They discussed the details of the plan for a bit before Ayumi suddenly remembered that she had come to call him for breakfast and patted his shoulder.
"Go eat in the living room. If we take too long, Akane will complain."
"Mm, okay."
The two straightened their clothes and walked out of the study together.
Entering the kitchen-dining area, they saw a thin-faced young man in a checkered shirt and jeans sitting at the table, head down, eating.
Akane was in the kitchen serving rice for them.
Seeing her boyfriend's big sister and lifesaver walking in together, Sawamura Asato lifted his head and greeted them with a warm, friendly smile. "Good morning, Ayumi-san, Sasaki-san."
Ayumi didn't react to the formal address, as he'd always called her that.
Sasaki, however, wasn't used to such an address and immediately corrected him. "Brother Asato, no need to be so formal. We're practically family now."
Hearing his words and looking at Ayumi standing beside him, Sawamura Asato smiled understandingly. "Then I'll call you Fuyumi. Don't stand there—sit down and eat."
In the kitchen, Akane finally finished serving the rice after taking her time and walked out slowly, placing the last plate on the table.
However, still not knowing how to face Sasaki, the girl greeted him awkwardly. "Good morning, Fuyumi."
Ayumi sat across from Sawamura Asato, and Sasaki sat beside him, returning Akane's greeting with a smile. "Good morning, Akane-nee."
Seeing that he seemed to have no memory of drunkenly pressing her head down last night...
Akane felt a sense of relief, but a faint, hidden disappointment rose in her chest.
She knew she shouldn't feel disappointed, after all, that was just a drunken mistake... but, no matter what, that was still her first kiss... given away so unclearly... her heart couldn't help but feel complicated.
Still, it was better this way; as long as she didn't say anything and pretended nothing happened, everything would stay the same.
Speaking of which... that huge thing had been inside her mouth... and then went into her sister's...
What to say..it felt so strange.
Embarrassed by her own thoughts, Akane absentmindedly returned Sasaki's greeting and sat across from him to eat breakfast.
Lost in her messy thoughts, the girl didn't notice the abnormal seating arrangement.
Two couples, four people... yet sitting crosswise...
As Akane ate bite by bite, her mind still in chaos from her sister and Sasaki's wildness all night, she suddenly felt something touch her calf under the table, sliding toward the opposite side.
Guessing what it was, she lowered her eyes and peeked under the table, and saw a plump, creamy-white leg boldly stretched across under the tablecloth.
Her big sister had always been bold and didn't care about others' gazes—she knew that.
But wasn't this a bit too much?
Not only did they keep her up half the night, but now even in the morning they wouldn't leave her alone... this was her home.
Was that kind of thing... really so irresistible?
To make her big sister tease Sasaki like this.
Envy for their intimacy, curiosity about what they did, and annoyance at being ignored like this it all made Akane unable to hold back, and she lightly kicked her sister's foot.
But...
She didn't touch her sister's feet; instead, her small foot pressed against a much larger one, bigger than hers by more than a size.
First came the confusion: 'When did Sister's foot get so big?' followed immediately by the realization that she had stepped on the wrong person.
Before she could hurriedly pull back, the foot beneath hers reacted like a crocodile waiting for prey—it snapped shut, trapping her foot tightly.
Shock and panic flooded her instantly, and she instinctively looked up at the opposite side, but Sasaki's gaze wasn't on her; it was on the person beside her.
"..."
