A/N - The following chapter is a special short story taking place in between Chapter 3 and Chapter 4. Reading it is not necessary to continue the story, as this chapter focuses on a more mature moment between Chinatsu and Akari. It's also probably the worst chapter in terms of quality so far, so my apologies. I struggle with these types of scenes.

Thinking back to the way things had been a month ago, Chinatsu could scarcely believe the situation she found herself in now. Back then, her biggest fear was the knowledge that she could so easily overpower her best friend, and Akari would be helpless to resist. Now, the very idea seemed so absurd. Just a glance from Akari was enough to drain Chinatsu's strength, and when that commanding tone entered her mistress's voice, the concept of defiance never even crossed her mind.

"Yoshikawa-san." Chinatsu didn't even notice as the teacher called on her, too busy trying to ignore the building pleasure, before all at once she let out a sharp gasp as it got more intense, bringing her focus back to reality. She glanced up to meet the teacher's gaze, trying her best to regulate her breathing, as she spoke up in a weak voice.

"Y-yes…?" She got a few concerned glances from her fellow classmates, but the redhead sitting next to her didn't show any sign that she noticed anything wrong at all as her hand left the pocket of her uniform.

"Yoshikawa-san, are you feeling unwell?" Originally, she'd called on her with the intention of answering a question, but now she looked more worried than anything else.

"I'm f-fi-haa..." She let out an all too obviously sexual moan as the pleasure spiked again, but no one else seemed to recognize it for what it was.

"Sensei!" Her patience having apparently reached its limit, Akari adjusted the settings one last time as she raised her hand. "I'll take Yoshikawa-san to the infirmary."

"I'll leave it to you then, Akaza-san."

"Lean on me, Chi." Not here... She nearly reached her limit right there. Being embraced by her mistress, surrounded in her scent, referred to by the name that only her mistress could use, and the vibrator that was now set to its maximum setting. In front of everyone...I can't…

At first, they didn't use toys or do anything this extreme, but at some point Akari had started to look into this type of relationship online, and after being exposed to all the internet had to offer, Akari's budding sadism had gone into full bloom. This had quickly become one of her favorite games, and as long as Chinatsu followed the rules, she couldn't say she didn't enjoy it; even if it was unbearably embarrassing.

None of their classmates seemed to suspect a thing as Akari led Chinatsu out of the classroom, although plenty of them shot the pair concerned glasses. Even with the support she got from leaning on Akari, she was still only just barely standing; making it seem like something really was wrong. Stop...looking at me...I can't…

Her body was trembling as she swallowed hard, desperately trying to hang on. Akari-sama will punish me if I let someone else see me…and she still hasn't given me permission... Akari loved watching Chinatsu squirm in front of everyone else like this, but Akari had made it abundantly clear that Chinatsu was strictly forbidden from letting anyone other than Akari witness her climax.

"I really can't get enough…" Chinatsu's mind was in such a haze that she couldn't tell how long they'd been walking for, and she had no idea where they were going. All at once, Chinatsu felt something cool against her back as Akari's lips found their way to her neck, and she let out a soft groan of pleasure as she realized she'd been pushed back against a wall. "...of that helpless look you make when you're so desperately trying to hold back, Chi."

"A-Akari-sama…" Chinatsu's breath was ragged as she struggled to spit out a protest, the incessant vibrations making it impossible to focus. "...w-we can't...n-not in the hallway…" Ultimately, she couldn't really refuse Akari. If her mistress decided that she wanted to do this in the hallway, then they would go through with it in the hallway.

"Don't be ridiculous, Chi." Akari accented every word by pressing her lips against Chinatsu's neck, each of her kisses deeper than the last before she pulled back to lock her gaze with Chinatsu's, the younger girl shuddering under the weight of her mistress's gaze. "You belong to me. I would never do this where someone else might see it. Every part of you is mine." Chinatsu leaned forward, eagerly submitting to the kiss she knew was coming as she felt Akari's arms wrap around her, pulling Chinatsu's body off the wall and pressing it against her own.

Chinatsu's body stiffened as her lips were forced apart by Akari, eagerly swallowing the saliva provided by her mistress; and the tension building within her finally seemed to snap, Chinatsu letting out an ecstatic gasp as the kiss broke, a wet warmth trailing down her legs as her body slumped weakly in Akari's arms.

"What a naughty little kitten. I don't remember giving you permission to cum." Chinatsu felt her body quiver as Akari spoke in that familiar tone, desperately trying to catch her breath, unable to muster even an ounce of strength; or voice the terrifying realization she'd just made. It's still...

"You look like you wanna say something. Maybe about this?" Akari had a sadistic smile clear on her face as she held up the vibrator's remote with one hand, her other arm still supporting the trembling Chinatsu's body. "But...a naughty kitten who disobeys her master needs to be punished, and that look on your face…" Akari let loose an ecstatic sigh, a look of satisfied desire clearly visible in her eyes as she squeezed her legs together. "...excites me more than you could ever know."

In the end, Akari didn't turn the vibrator off until Chinatsu fainted from exhaustion.

Chinatsu stared out one of the windows of the infirmary in silence. After she fainted, Akari had taken care of the clean up and carried Chinatsu to the infirmary before heading back to class. When she first woke up she had checked the time, and considering the school day was ending in just a few minutes, she had decided it would be a waste to go back to class now.

Besides, she had something more important on her mind anyway. "I hadn't realized it until now, but there are still lines Akari isn't willing to cross. No, that isn't quite right. I've known it for weeks now, but I didn't want to accept it." Akari had done a lot with Chinatsu, but the most that Chinatsu hadn't really done anything with Akari. Even the kisses they shared were always initiated by Akari.

Every time Chinatsu tried to initiate anything, Akari always refused. Chinatsu hadn't given it much thought until now, because she was content just to enjoy their relationship, but when she gave it some thought; she was pretty sure she understood. "She doesn't let me do anything with her...because that would be crossing the line she established…" Because there was no way that Akari could keep her feelings separate from their relationship if she let Chinatsu kiss her, or if she let Chinatsu return the favor when they did something like what happened earlier.

"She always said that just watching me writhe in pleasure was enough for her. What a liar." She found herself thinking about the conversation she'd had with Chitose the other day, a small smile spreading across her lips as she reached a decision. "I guess it wouldn't hurt to agree to a few dates. Even if I don't end up falling for her, I know she'll do everything she can to make sure I enjoy it."

"That's just the type of idiot she is." Chinatsu couldn't help but feel as if a weight had been lifted from her shoulders. "She never puts her own feelings first."
