Y/n POV
I really dont.
Y/n: Jungkook n-not here.
Jk: where do you wanna go babygirl?
Anywhere Jimin isn't
Y/n: Somewhere where we wont get caught.
Jk: Why not just let me fuck you here so Jimin can know who you fully belong to?
Y/n: Jungkookie~
Jungkook pulled me to the backyard and back there was a really big space with a little shed back there. He took me inside and pushed me on the wall.
Y/n: Jungkook we just did it like a few minuets ago. Not even an hour yet. It hurts still.
Jk: Trust me i'll make you feel good.
Jungkook bent me over the table that was in the shed. The table had a cloth over it. Jungkook enters me from behind. He starts off slow because I haven't got it done from the back before. I moaned lightly.
Jk: Y/n Ahhh~ Moan louder Ahhh~ babygirl.
He said it so seductively I could cum from just hearing that.
Y/n: Jungkook~ fast-er~ jebal oppa.
He sped up the pace. I know this is wrong but it doesn't feel wrong. How do you expect me to stop if this feels so amazing. At least Jimin was my first. I think me and jungkook did "IT" more than me and Jimin. My own boyfriend.
I was lost in my thoughts. I was moaning but i was thinking hard about Jimin. My thought were interrupted when *slap*
Y/n: AHHH~
Jungkook just slapped my ass for no reason. Ok i see how it is. 2 can play at this game.
I squeezed my hole around his dick causing him to go harder into me.
Y/n: AHHH JUNGKOOK~ FUCK~
I screamed it so loud. OMG! Im screwed.
Jk: Good job babygirl. Just like that.
Y/n: HARDER!! IM ALMOST THERE~
I was like in a trans. I finally came after a few more thrust.
Jk: That was amazing babygirl. Just scream louder next time.
Jungkook licked me clean. We fixed our clothes. There was a white puddle of cum underneath us.
Jimin POV
I was minding my own business when i suddenly heard. "AHH JUNGKOOK~ FUCK~
Jimin: What the hell? That sounds like Y/n.
I walked to jungkook's room. No sign of him. I walked to y/n's room. No sign of her. There spending to much time together
"HARDER IM ALMOST THERE~"
That really sounds like y/n. I followed the sound and ended up at the shed in back yard. Wierd. I peeked through and saw the most heart breaking sight. Jungkook was holding Y/n's waist. His face was inches from her's. He kissed her and she didn't even stop him. I looked down and saw a white puddle. It looked like throw up from where i was standing.
Jk: That was amazing babygirl. Just scream louder next time.
What the hell y/n. I was crying before i even noticed. Wasn't it supposed to be the boy who cheats on the girl and not the other way around.
I guess this is what I get for trying to stay loyal.
I walked away. I went to y/n's room and looked at her bed. What if they did it in here too?
Time for payback y/n.
I got my things and walked downstairs. I saw y/n and jungkook laughing in the kitchen.
Jk: Oh Jimin. We still on the for the bet right?
Jimin: No.
Jk: Why not?
Jimin: Cause i quit. Don't fucking talk to me. Wait. Don't you have someone else to fuck.
I looked at Y/n then left. I didnt look back.
Y/n's POV
What the actual fuck.
Jk: Looks like he found out.
Jungkook was smiling.
Y/n: WHAT THE FUCK JUNGKOOK!!
He stopped smiling and looked at the table.
Y/n: I told you to stop but you didnt. Now look.
Jk: You saying this like it's my fault.
Y/n: It is!
Jk: Not 100%. It's only 50% my fault.
Y/n: How?
Jk: I didn't stop when you asked me too. Thats my 50%. You didnt try really hard to stop me either. As a matter if fact you said don't stop. Thats your 50%.
I was speechless. He was right.
Y/n: Fuck me.
I thought i said that in my head. Turns out I said it out loud.
Jk: I just did. But i can always do it again.
Y/n: Jungkook shut up. That's not helping. You don't even know if he really found out or not.
Jimin POV
I went out. I went to a club and had like 5 drinks and then went out for a walk. I walked to a bench at a park. I sat there and stared at the stars. (It's night time now BTW) I was thinking about y/n. How could she do this to me. It would make sense if I cheated on her too. Maybe I should. I think i will.
I kept walking. There's this girl from school I saw. I knew she had a crush on me. Maybe I could get her. What was her name again. L-i-sa. Lisa. Yeah that was her name. I walked up behind her and grabbed her ass. She flinched. She turned around and look agitated but then smiles when she see's me.
Lisa: Hey Jimin.
Jimin: Hey Lisa. What you up to?
Lisa: Just waking around ya know?
Jimin: Yeah. Wanna go to a hotel or somethin.
I'm not in my right mind right now but the way her body is lookin. I just cant help it. Maybey I had too much to drink.
Lisa: Right now?
Jimin: Yeah let's go babygirl.
TIME SKIP (Too Lazy)
I was about to cum. A few more thrusts and I would cum.
Jimin: Scream my name babygirl.
Lisa: AHHH~ JIMIN!~
Jimin: Y/n~
I pulled out.
Lisa: Jimin? Did.....you just....say.....Y/n?
She said in between catching her breath.
Jimin: No.
I said cold and flatly. I got my clothes and out them on. I was on my way out the door.
Lisa: Wait. Where are you going?
Jimin: Home. You can stay here. I rented out the room until 10:00 tomorrow morning.
After saying that I left.
