Step Siblings

The Party

Marinette's POV

( 4 months later)

So I was in my room when I heard extremely loud music. I then went out my room and I looked from the top of the stairs and saw a whole bunch of college students partying. I leave Adrien alone for one second and he's throwing parties. Might as well join mom and Gabriel aren't going to be home until next week. I went to my room freshened up and got dressed.

I went downstairs joining the crowd. I started to look for Adrien . Boys were staring at me and I mean mugged them but they found it more attractive . Then one slapped my ass and I glared and smacked them in the face. Everyone was like DAMN that's when Adrien appeared . He saw me and came over and looked at the guy.

Adrien: what did he do to you, did he hurt you

Marinette: no , he slapped my ass which is disrespectful so I slapped him in his face

Adrien: nice job

Marinette: thanks

Adrien: so you finally joined the party well come on I have some people I want you to meet

Adrien grabbed my hand and guided me through the crowd. We then stopped and he put me in front of him and wrapped his arms around my waist. I was facing three girls and two boys.

Adrien: everyone I want to introduce you to my girlfriend Marinette

Alya: wait isn't your step sister named Marinette is this your step sister

Tikki: can you even do that

Plagg: i don't even know

Nino; woah

Chloe: Adrikins you can't date her she's your step sister that's incest but you can get with me instead

Marinette: actually no,  key word step  sister which means we're not related in any type of way technically so that means you need to back off honey because he's mine

Alya: wow you pack a lot of sass for 18 you'll fit in just fine welcome to the group

Tikki: yeah

Plagg: ditto

Nino: welcome dudette

Chloe: ( scoffs) as if

Then she walked away and Adrien pulled me closer.

Adrien: want to dance

Marinette: yeah

Then we both joined the people dancing. After a while Adrien went to get us drinks and I felt someone grab my ass. I quickly grabbed that person by the neck. I turned to look at them and saw Nathaniel. I glared and pushed him away.

Marinette: fuck off, dipshit

Then he just smirked and walked closer. I then glared harder.

Marinette: back the fuck up off me tomato

Nath: I know you miss me you're so lonely

Marinette: actually I got a new boyfriend so I'm fine, now do me a solid and back the fuck up, bitch

Nath: who

Then I saw Lila the girl he cheated on me with and she looked at me and him glaring.

Lila: what are you doing talking to this bitch

Marinette: don't call me a bitch you fucking whore , I dare you to call me a bitch again

Lila: bitch

Marinette: exactly bitches do what they're told, see you around

I then started to walk away everyone around us was like Damn. Then she yanked my hair. I then tied my hair up and got to mopping her ass.  Adrien then came and pulled me off of her. He then kissed me to calm me down and he looked concerned.

Adrien: what happened

Marinette: she called me a bitch, I roasted the shit out of her,and she pulled my hair  , and I mopped her ass, why did you invite her and Nathaniel anyway

Adrien: I didn't I just told people to come I didn't know she was the one he cheated on you with

Marinette: well yea that's her

Nath:so where is this boyfriend you were talking about

Marinette: it's Adrien

Nath: but he's your step brother

Marinette: not biologically related

Nath: well I want you back

Marinette: not happening, now tend to your girlfriend

Me and Adrien then walked away from them .

Adrien: I didn't know you could fight that good

Marinette: eh no biggie

The party was now over and everyone left. We cleaned up then passed out on the couch together.
