Stepbrothers • A BTS Dirty Fanfiction

Chapter 3

I wake up from hearing a knock on my door. I check the time on my phone and see that it reads 5:56 pm. At first I was confused but then I realised that I fell asleep earlier on today. I get up to see who was at my door. I open it to see Jimin. He looks at my messed up hair and giggles.

"Wow sis you're looking hot" He jokes. I roll my eyes and try to sort my hair out.

"What do you want Jimin?" I ask, walking to the mirror in my room, he follows me in.

"Well dinners ready, your mom told me to come tell you as you were still asleep" He says, sitting himself on the arm of the couch.

"Ahh I see. Also what is up with your brother?" I ask, facing him. He looked confused.

"Which one?" he giggled and I scoffed. "The one who slapped my ass and said he couldn't help it?" I say, thinking about that time and shivering.

"Ohhh Jungkook, yeah I think he likes you" Jimin says, looking at the floor. I stare at him wide eyed.

"What!? I'm his sister now he c-can't like me!" I say, still shocked.

"Come here" He says, holding his hands out. I walk up to him and he pulls me into a hug. I close my eyes and lay my head on his shoulder.

"You're his step sister Y/n. He can feel whatever he wants to feel" He whispered, caressing my hair.

I roll my eyes again and lift my head off of him. "whatever, it's still wrong to me" I grab my phone and head downstairs, Jimin follows behind.

I walk into the dining room to see them all waiting for me. I send them all a 'sorry' smile before looking for my seat. I hear Jungkook call my name.

"Y/n, there's a space here" He smirks, pulling out a seat right next to him. I smile falsely and dart towards the other free chair.

"um no thanks I will sit he-"

"um that's my seat" Jimin says, sitting down and smirking at me. I give Jimin the evils as he knows that I don't want to sit by Jungkook. I stare at the seat and I feel a hand come up my back. I gasp to see Jimin making a shushing gesture with his other hand, making me very tense. Everyone was eating so they didn't notice Jimin's evil actions.

"Y/n stop being so rude and go and sit by your brother!" My mom says. I huff and roll my eyes.

"Fine!" I say, throwing Jimin's hand off my back and walking up to Jungkook. I pull myself in and give him a sly gaze.

"You try anything, you will die" I mumble to him. He chuckles and looks away to talk to another boy I still didn't know the name of.

We all had a nice chat and I finally knew everyone's name. Jungkook hadn't tried anything which I was happy about. So obviously he can help it. I wipe my mouth and pull myself out from the chair.

"I'm gonna go upstairs now and watch some Netflix, I will see you all in the morning." I smile, before walking through to the entrance hallway. I suddenly hear Jungkook tell my mom and dad the same thing. I close my eyes and start running up the stairs as quick as I could. But I tripped up on the stairs. I groaned angrily at myself. I picked my heel up off of the stair and kept running. I managed to get to my room but so did Jungkook. He pushed me in, closed the door and pushed me onto it hard. I gasp and pant from tiredness. He looks me up and down and wasn't even one bit tired from running.

"Is my baby tired?" He whispered into my ear. I go to slap him but he grabs my arm and pins it up next to me. He does the same with the other hand. I try to squirm but he grips harder.

"Jungkook y-you're hurting me" I say, innocently but I was trying to stay tough.

"Well maybe I wouldn't have to if you were a good girl and didn't try to fucking slap me, you brat" He says, positioning his lips on my neck. He starts kissing down my neck gently. I wanted him to stop but at the same time it felt nice. The kissing led to sucking as his hands began to explore my now tensed up body.

"Jungkook why are you doing this?" I choke out. Suddenly there was a knock on the door. He grabs me and pushes me onto my desk chair. I sit up in the chair as Jungkook goes up to the door. He opens it and smiles like his usual bunny self. The door opened to Jin and Namjoon. They looked at Jungkook weirdly.

"Why are you in Y/n's room?" They ask him.

"Why you knocking on Y/n's door?" he argues, clearly angry that they interrupted.

"um dad told us to give her this" They said really confused.

"OMG WHAT IS IT?!" I say, getting off the seat. I see Jungkook watch as I run up to them. He didn't look happy.

"Y/n go and sit down!" He says. I look at him angrily. I wasn't going to let him boss me around like this.

"WHY? WHY ARE YOU-"

"SIT DOWN!" He says, hurting my ears. My other stepbrothers looked shocked at his behavior just as much as I was. I didn't think he was like this.

Jungkook's PoV

I'm never usually like this but if the boys find out I like Y/n they will like her too. They always copy everything I do. Why can't they live their own fucking independent life instead of using mine?

"OMG WHAT IS IT?!" Y/n shouts, as she hops off the seat. I see her come past me and her hickeys were clearly visible. I stare at them and start to get worried. I couldn't think of any excuse quick enough and all I could do was shout.

"SIT DOWN!" I screamed. She covered her ears and went to sit back down. That was close.

Y/n's PoV

"Give me it" He said to them, even though he grabbed it out of their hands.

It was something small and shiny in a black velvet box but I couldn't quite see what it was.

"So why are you in her room!?" They ask again, being the protective brothers they should be.

"I'M HELPING HER WITH HER HOMEWORK! NOW LEAVE!" He shouts again, slamming the door in their faces.

Jin's PoV

Jungkook slams the door in our faces ignorantly. He is never like that. What has gotten into him?

"Wait" Namjoon starts. "She doesn't have homework, She starts school on Monday".

I looked at his shocked face and he looked at mine. We heard a shriek from inside the room. We decided to listen for protective purposes. If he wasn't helping her with homework, what was he doing?

Y/n's PoV

I started to zone out until he comes right up to my face. I shriek and pull my legs up to me. He grabs my t shirt in a fist and pulls me closer.

"You tell anyone about this, It will only get worse" He says, with an evil smirk. "And also, you'll need to cover those. I bruised you a lot" he smirks, eyeing my neck. I guess he was referring to hickeys he must have left on me. He kisses my lips harshly and I cringe. He headed to the door and leaves, closing it behind him. I let out a sigh and check the hickeys in the mirror, glaring at the dark marks he had left on me.
