My Girlfriends sister P2 (Yelena X Reader) {F}

After my shower with Nat we sat and watched some dumb action movie in bed, to be fair I wasn't really watching it, I was to busy thinking about Yelena... My girlfriends sister! I know I keep saying it but I have to keep reminding my self, I KISSED MY GIRLFRIENDS SISTER! Thank god I'm not dating Wanda my thoughts are so loud right now.
"Y/n? You okay?"
Nats voice broke me from my thoughts. I looked over to her side of the bed met by worried eyes. I smiled at her with reassurance.
"Yeah, of course I was just thinking about my last mission, I'm just going to speak to Wanda about it I'll be back in ten?"
Nat nodded as I pushed my self up and made my way to Wandas room. She's my best friend I'm sure she will understand and maybe help... Hell who am I kidding I just needed to admit what I'd done to get it out my mind. I knocked on the hard wood door and I heard wandas soft voice behind it telling me to come in. I slowly opened the door head dropped practically on the floor.
"Whats wrong? Trouble in paradise?"
Wanda laughed thinking her comment was way off the mark. I looked up at her and didn't say a word. She was right there was trouble in paradise, I just didn't know her to admit what id done and I didn't want anyone to be mad at Yelena.
"Wait there actually is trouble in paradise? Shit what happened?"
I took a deep breath and sat on the side of her bed trying to find my words. I knew I just had to say it right? Right.
"I kissed Yelena."
The room fell silent and my eyes where glued to the floor. I'd said it out loud now. It was real. I kissed my girlfriends sister, and now Wanda knew about it too. All I wanted was for her to say something, anything, but she didn't. I felt her eyes on me. She was waiting for me to say something, I was waiting on her. I was in the wrong I knew it was on me to say something first.
"It just happened. I- I didn't mean for it to happen."
"But you did it y/n."
"I know..."
"Have you told Nat?"
"No! I can't it'll break her heart."
"Of course it will you kissed her sister!"
I sighed and looked around the room for an escape. This didn't go how I thought it would. But fuck, Wandas right. Ugh right I got to do this.
"I'll tell her soon."
"No Y/n you'll tell her now."
"Wanda, that's not fair..."
"Listen, you're my best friend, so is Nat... she needs to know and it has to come from you."
"I know but I don't know how..."
"You need to figure it out and tell her Y/n, or I will."
I sigh again and get up to go tell Nat. I open the door and turn back to Wanda who's giving me a hopeful smile, and with that I leave. I was lost in my thoughts before bumping into someone.
"Oh sorry, my bad."
"I- erm, its okay."
I finally realised it was Yelena I ran into and suddenly the hall felt small and full. I looked at her then realised I had to tell Yelena I was going to tell Natasha.
"Listen Lenny I have to tell Nat."
"What?! No, you can't."
"I have to, she's my girlfriend!"
"And she's my sister y/n!"
"Exactly and your my girlfriends sister!"
She didn't say anything to me after that but I could tell she knew Nat had a right to know.
"I kissed my sisters girlfriend..."
Yelena voice quite and guilty finally admitting what she had done. I sighed.
"Lenny its not just on you... I've wanted to do it for a while but I love Nat so I ignored the feelings I had for you."
"You have feelings?"
"Yeah I guess."
I glanced at Yelena lips as she licked them slightly. God, why is she so kissable. I kissed her. Fuck, I know its wrong but god her lips feel good on mine. She kissed me back and her arms lay on my shoulders as my hands found her hips.
"What the fuck?!"
Nats voice came from behind Yelena making us jump apart. Shit.
"Nat I can explain..."
I saw Nats eyes filled with anger, but not at me at her sister.
"I'm going to kill you Yelena!'
