dabi x reader (strong y/n)

problems ig

"So? Now that you kissed me out of nowhere , what are we supposed to do??" I asked unsure "heh why are you reading in it, its just a kiss, nothing more nothing less..." he said at my big surprise *ah is that how you wanna play it, in your dreams.* "you deepshit, now that you did that, dont you dare back off and pretend nothing happenned" "and what if i do?" "You're gonna regret it" i said smiling, "i would love to see it" he replied grinning.

"GUYS, WHERE ARE YOU??" it was kurogiri calling us, "right here" i replied passing in front of dabi *time to go back*

"Y/N, I MISSED YOUU" toga happily greeted me , "i missed you too little girl" i said patting her head, "still as gloomy as ever" she said this time looking at dabi "more than ever" i sighed half smiling...

After going to the bathroom i went back to my room to change when i saw dabi on my bed, visibly waiting for me, "why are you here?" I asked him tying up my clothes "waiting to settle things" "whats things" "you thinking we are something" he said getting up frowning his eyebrows "mmh is that so? We're not something but you're mine so you better not cheat" "and why's that?" "Cause i'll fuck whoever you did it with" i said with a wink, going out of the room,* i dont know if he understood the real meaning but its gonna be fun letting him discover* i thought laughing…

*the night after*

"Y/n, my office now." Shigaraki ordered me "coming right now", i said closing the door behind us "you have a mission, you have to find more informations about the teachers that are coming to the trip with the students."
"Sure" "take dabi with you" "i will."

I looked for him, where the fuck is he??? 

I opened the door and saw him on the sofa, a girl sitting on his laps and kissing the hell out of him he had lipstick marks all over his chest... 

"oh hey y/n" he dared to say, *mmh is that how you wanna play* i smirked and went to him *if he thought i was gonna cry he's hardly wrong* i took the face of the girl *not my type but pretty* and kissed her as dabi watched us choked, i deepened the kiss when i smellt something burning, it was the sofa.

i took the girls arm and made her stand before she gets hurt "you were incredible girl" i said to her with a wink as she blushed and went out the door, i looked at dabi he was furious, *serves him right* i thought "well such a waste that she left, but you see it was not my main goal, shiggy gave us a mission" i said "oh and you better stop since im still nice, cause if you try treating me like an option i'll show you how many i have" i added before going out of the room letting him moveless on the mid burnt sofa.
