Mai was sitting on the couch, her legs pulled underneath her, a book in one hand and the other lightly sifting its way through the dark mane belonging to the young girl lying on her lap. She untangled her hand to turn a page when she heard the sound of the door opening. Mikoto hadn't moved, so it had to be someone they knew, few were welcome to come in without knocking. She glanced at the clock her first assumption was that it had to be Natsuki, but Natsuki always opened the door loudly and came stomping in, no matter how her day had gone.
When she turned around to see who it was, Mai fumbled with her book nearly dropping it in surprise.
Natsuki was leaning against the closed door, two fingers hovering over the smile on her lips and her other arm wrapped around her middle. There was a faint blush upon her cheeks.
"Natsuki?"
Natsuki looked up, a glazed expression across her face before she shook it off and glared at Mai. Or at least attempted to, it didn't have much effect because that silly smile was still plastered on her face.
"What?" She growled, the smile never wavering.
Mai stared at Natsuki with a wicked grin, "I take it she kissed you?"
"Shut up! It's none of your business!" Her smile grew wider.
"Aw, how cute! Natsuki got her first kiss!"
The blush grew ten levels and the smile lit her face. "Idiot!" Natsuki shuffled her feet. Embarrassed as she was, she couldn't help but feel like she wanted to tell Mai everything. Ug! I am not some squealing little girl!
"At least tell me about the dinner."
Knowing that Mai would bug her constantly, Natsuki sighed and sat on the opposite side of the couch, pushing Mikoto more towards Mai. She proceeded to tell Mai what had happened that night, an extremely short version of course. She still wasn't used to telling anyone about her day, but Mai was slowly working on that and Mai hoped that being with Shizuru would help Nastuki, as well.
It was then Natsuki started to panic, "Mai! She has a sister! An older sister! She said she's worse than her and her mother! Do you know what that means!?" Her voice was frenzied and slightly high pitched.
Mai blinked, "She has a sister?"
"That isn't the point!"
"Wait, you mean there's someone more beautiful and resourceful than our Kaichou-sama?"
"She is not more bea—!" Natsuki stopped herself, glaring at Mai, "What exactly are you getting at, Tokiha?"
Mai picked up Mikoto, who had an uncanny ability to bury herself into Mai's chest no matter how dead asleep she was, and backed up towards their room before adding gravely, "You had a good life, Kuga, a good life."
Natsuki was then left to stare dumbly at a white door.
"What the hell is that supposed to mean?"
Shizuru gave her mother a hug before starting her trek up the stairs towards her room. She stopped half-way up and turned to face her mother, who was still standing at the bottom of the steps, looking up at her daughter. "Thank you, Mama." Shizuru said with a smile.
"For what, dear?" Kyouko started up the stairs stopping as soon as she reached Shizuru.
Shizuru held out her arm for Kyouko and waited for her to intertwine her own arm before continuing up the stairs, "For not scaring my Natsuki." She paused for a second before letting out a small chuckle, "Not too much, that is."
"Of course, sweetheart. I wouldn't want to scare off someone who makes you so happy." As she said this, Kyouko placed a comforting hand on Shizuru's cheek. She wiped away a tear that suddenly rolled down Shizuru's face. Kyouko reached up and kissed Shizuru's forehead, "Though, my little kitsune, you may want to warn her about your sister. I'm surprised you never mentioned her to Natsuki before."
Smiling Shizuru hugged her mother again before turning to her room, "Ara, I had to make sure Natsuki wouldn't stray first."
"Or rather, so Akiyo wouldn't take her first?"
Smiling, Shizuru nodded. "She would have tried, if not just to tease me, but she never would have succeeded." Shizuru stated seriously.
Her mother blinked for a second at the possessiveness that had colored Shizuru's voice. She then smiled knowingly, "You know she never would have hurt you."
"I know Mama, but there are times..." Shizuru trailed off, not really having to voice her reason.
"She only does it because she loves you, and is probably testing the young woman to make sure she's loyal to you and only you."
Shizuru huffed but nodded; only her mother could get her to outright act like a normal child, and her sister. Despite Akiyo's audacity for flirting with anyone Shizuru showed interest in, she knew her sister was protecting her. If she really thought about it, Akiyo never actually dated anyone she 'pulled' away from Shizuru. As if I were truly interested in them.
Most that her sister had scared off were girls and boys who greatly admired the kaichou; none had managed to genuinely gain her attention. Natsuki had sorely taken up that position the moment she stepped into Shizuru's view.
With knowing her sister's reactions towards those who admired her, Shizuru never let Akiyo see Natsuki. There were some forms of torture she wouldn't let her Natsuki endure, at least not alone. No, Shizuru would make sure, for now at least, that she was near whenever her sister and Natsuki were in the same room. If only, of course, for Natsuki's own safety.
Kyouko patted her daughter's cheek once more, placing a light kiss upon it before bidding her goodnight.
"Good night, Mama," Was Shizuru's reply, as well as a tight hug of gratefulness for the night's proceeding.
Kyouko patted her daughter's back before pulling back and smiling, "Now sweetheart, don't spend too much time tonight thinking about that young pup of yours. I'm sure your father will wish to hear all about her tomorrow morning and we don't want you staying up half the night with forbidden thoughts." The older woman teased.
"Mama!" Shizuru said and her blush nearly rivaled one of Natsuki's. Shaking her head she gave a small laugh before saying goodnight to her mother once more and headed into her room.
"Ara, forbidden thoughts, indeed."
