A/N: Okay so this one just appeared during a conversation with Pewdepew, he gave me his idea that he got from some anime (forgot the name) and I somehow ended up typing all these. So he deserves credit for this. Thanks a lot mate, this chapter is dedicated to you!

Disclaimer: I don't own Oregairu.

Edit: This chapter's events are NOT connected to the others. This was originally intended to be a collection of drabbles, however it changed into a single story at some point. Thanks to a certain guest review for pointing this out! Props to OmegaEleven for his suggestion to rename this chapter.

'What the hell am I doing? What the hell have I become...'

His thoughts battered him with questions on his own actions as he once more found himself alone with her, the bubbly, pink-haired girl with the uncanny ability to yank him away from his lonesome.

It wasn't like he couldn't say no. But once he tried to resist her, she'd attack him with those puppy dog eyes and pout in a way that he swore his conscience would never let him rest.

"Hikki..."

His rotten eyes moved their gaze from the crack on the wall he convinced himself to be interesting towards the girl in front of him. Her fingers fidgeted while her hips swayed a little from side to side as if taunting him.

"Yeah?"

"P-please be gentle with me..." She had her head low, her eyes looking up to meet his. "Okay?"

There was definitely something wrong with the situation, and as much as Hachiman wanted to escape from it he found himself unable to do so. The redness of her cheeks, the glossiness in her eyes, the innocence in her voice...

There's something about Yui that somehow effortlessly beguiled him into submission.

"U-unn, sure." He scratched his cheek, averting his stare in an attempt to prevent the effects of her charms from deepening their hold on him. "So... what now?"

"We can start with this." Yui put the toilet lid down and sat on it. "It's easier if we do it like this... don't you think?"

"I-I guess..." He walked over towards the sink and washed himself first, making sure that he was clean before he began his task. Hachiman then walked over and stopped in front of Yui, the girl's face conveniently positioned at the right angle.

"Are you really sure you want to do this?"

"Yes, I'm sure." She spoke, almost like a whisper.

"Alright then." Hachiman used his one hand to hold her by the chin, the other to hold himself properly for her. "I'm gonna start now, okay? Let me do the work and just stay still for now."

After an affirmative nod she opened her mouth, and without further ado Hachiman complied with her request.

He thrusted in and out of her orifice in slow, calculated movements. Her face now blushed harder and she had eyes shut, unable to look at him out of embarrassment.

Hachiman kept up a serious facial expression, hiding the growing adoration he felt at the sight of the girl. He felt a slight sense of domination over her, with how he had her face in his hands as he slid himself inside and out her, again and again.

"Mmmmm..." She mumbled her words as her mouth was currently filled with him, however the look on her face told him that she was somehow enjoying this.

He made sure to cover every last bit of her, grazing the inner sides of her cheeks as well as her tongue. He felt the muscle move as it made contact with him, pushing him around as it seemed to coil around his length. The elicited response led him to explore further and upon doing so Hachiman accidentally pushed himself a bit too far inside, Yui's gag reflex kicked in and she began to cough, causing him to stop and pull out at the moment to let her recover.

"S-sorry." He apologized, seeing tears at the corner of her eyes.

"It's okay, c-carry on..." She said, almost as if pleading for him.

He resumed his work and this time he made sure to be gentler on the girl, to let her feel him upon each stroke that took them nearer to the finish line. Once he was almost done he let himself roll on her tongue one last time before pulling himself out, Yui covered her mouth with her hand as he made his exit.

"Okay, don't swallow it now." He instructed, watching her rush towards the sink.

"O-of course I won't! I'm not a child, you know!" She retorted with the mess still inside her mouth childishly, quite ironically.

After she spat out the white stuff that had accumulated inside her during their little activity, she went onto rinsing. Hachiman simply watched in silence as she finished herself, turning to face him and flashing her pearly whites, now clean and sparkling.

"I still don't get why I have to brush your teeth." He shook his head at her display, not giving her a chance to notice his amusement on her behavior. "You're not a child, you know."

"Uwaaaa!" Komachi squealed to herself as she still had her ear pressed upon the bathroom door. Her Hachiman senses tingled earlier after seeing him come home with Yui in tow, and as she had guessed she managed to secretly spy on their little ritual.

Not wanting to be caught eavesdropping she retreated towards her room immediately before the two officially ended their private moment.

"Great job Onii-chan! You just scored a lot of points in Yui-chan's book!"

A/N: Komachi seems omnipresent... and omniscient. One word away from being a god there.

Something short to rinse the taste of my other one-shot from my mouth.

Again, thanks to Pewdepew for his idea!
