Ayato X Reader- Possesive

(Tokyo Ghoul) Ayato Kirishima X Reader
“A~ya~to~ Get off my couch” You drawled from the corner of the room.
“No. Stop being such a whiny little bitch, Aho (Name)” He scowled refusing to move. You stalked towards him like a cat chasing a mouse and pounced, draping your arms around his neck as he flicked through the channels absent-mindedly.
“But Aya-chan~ I’m lonely~” You whispered in his ear, smirking as you felt him shiver.
“Call me that again and I will kill you. Take your filth hands off me.”
You swore he was tsundere. But oh well he was much more fun to tease that way (even if you did end up bruised in the end)
The Aogiri Tree members were incredibly shocked when you first joined them. You had clung to Ayato and refused work with anybody else. They were even more surprised when Ayato did not proceed to beat you to pulp and kick you out of his group (He had pulled you off him, kicked you into the wall and left the room but that was a really light sentence coming from Ayato). Rumour had it you looked like his sister but you acted nothing like her.
“Let me think about it… How about no Aya-chan~” You grinned and gently tugged his dark blue locks. Ayato bit back a groan, why did you have to be so damn (attractive) annoying?
Pulling your wrist towards him, he pulled you over the back of the couch and onto him. It was his turn to smirk “Since you can’t seem to keep the loud mouth of yours shut- how about I shut it for you?” you expected to get kicked off the couch but what came next was a pleasant surprise. Ayato pressed himself against you in an aggressive kiss, you refused him entrance. He growled and bit your lip harshly, before sliding his tongue in an open mouthed kiss. You let out an involuntary moan and he smirked in victory.
Tatara watched from the doorway, smirking knowingly. About time you two got rid of that sexual tension.

It was only later in your relationship did you realise just how possessive your blue haired ghoul boyfriend could be.
“Aya-chan,
I’m going dove hunting with Tatara-chii~ See you later
XOXO
(Name)”
Ayato clenched his cell so hard, he nearly broke it when he read that text from you. He growled lowly.
“K-Kirishima-sama t-the k-king n-needs to s-speak t-to you-eek!” An unfortunate subordinate ghoul interrupts his jealousy induced tantrum.
“Well then. You tell him he. Can. Wait.” And with that he proceeded to continuously kick the poor unlucky ghoul several times, before the ghoul passed out and left him there to die.
“There’s someone I need to hunt down and kill.”
Meanwhile you and Tatara were having the time of your lives killing doves like flies. It was too easy really. That is until Ayato showed up.
“Oh~ Hello Ayato come to join in on the fun?” You giggled from behind Tatara and single-handedly defeated another CCG without blinking an eye and chatting with Ayato.
“What are you doing.”Ayato glared harshly at you, advancing slowly.
“What? Didn’t you get my text? I’m dove hunting with Tatara-chii~”
Tatara almost facepalmed. Didn’t you get it?
“I meant what are you doing with him.”
“Nothing…?” You stared at him in confusion. Without another word Ayato picked you up threw you over his shoulder and glared daggers at Tatara.
“You, shitty white haired bastard. Stay the fuck away from her or I’ll make sure you die a slow painful death”
He left swiftly but not before sending a few bullets from his kagune at him.
Ohhh… you got it now.
~Extended Ending~
“Aya-chan is jealous~” You sang cheekily.
“Shut up. I was not.”
“Oh I see~ well then I’m going on a date with Tatara-chii~” You grinned. In a heartbeat you found yourself caged against the wall with Ayato mere millimeteres away from your face.
“You do that and I’ll punish you so hard you won’t be able to walk straight.”
“I’m looking forward to it Aya-chan♥~”
You were the only one allowed to call him that. But he wasn’t about to tell you that.
