-Unfaithful-

Wrong idea

Hi! Sorry I haven't updated for the past few days literally have no reason.Anyways enjoy chapter 2!

Smut warning💁This is my first time writing smut so try to hang in there with me.

Mikasa POV

Me and Armin finished hanging out at his house,we pretty just talked and drink tea together.I know he's my best friends boyfriend but I love him.I can't stop seeing him just keep my friendship with y/n alive.We were walking to my shared apartment with y/n.I wonder what her and Eren we're doing while I was gone.I grab my keys and unlock my door,me and armin walked to see no one in the living room or kitchen.That means they must be in the bedroom."Where are they?" Armin says while looking at me with confusion."The only other place they can be is in the bedroom,let's check in there." I say to him he nods.We walked into the bedroom to see Y/n and Eren sleeping in y/ns bed.Anger instantly filled my body.I rush over to her bed and snatch away the blanket from them.Y/n instantly woke up while Eren remained asleep."Mikasa what the hell!"She says with a annoyed face."WHY ARE YOU AND MY BOYFRIEND SLEEPING TOGETHER!" I wanted to slap y/n,but did I really have the right to be mad?I was actually having sex with her boyfriend,she was just sleeping in the same bed with eren.Y/n got a confused face while looking at me then she looked at eren and back at me,her eyes shot open."MIKASA IT ISNT WHAT IT LOOKS LIKE,YOU GOT THE WRONG IDEA!"She said while trying to grab my hands to calm me down.What I did next surprised me I couldn't believe I did it,It didn't feel like I was in control.I pulled my hands away from Y/ns and slapped her hard on the cheek.Then Armin came and pulled me back from Y/n."MIKASA SIDNT YOU HEAR Y/N YOU GOT THE WRONG IDEA"Armin said while looking at me in the eyes.What I didn't know that Eren was really awake after I pulled the blanket off.He was sitting up in the bed watching.I looked back at Y/n with her holding her cheek.She had some tears coming down it.Eren got up and walked to me and pushed armin out the way,then grabbed my hand and brought into the living room.

He still didn't say anything he then sat down with me on the couch."Mikasa why didn't you listen to Y/n,she's right you have the wrong idea" he said while looking at in the eyes,I responded with"Then tell me what happened then"."Okay,Me and Y/n were just watching movies and fell asleep in the bed there's no reason to mad."He said while kissing me on the forehead.I felt horrible eren was right,there is no reason to mad.It was a stupid thing to do,I can't believe I slapped Y/n.I was fixing to get up to her sorry,when eren stopped me."It's the first time she's seen armin in weeks let them be alone for a couple minutes." Eren said"Okay".Me and Eren started talking while on the couch.

Y/n POV

I was holding my cheek trying comprehend what just happened,then I saw Eren bring Mikasa out of room.I let go my cheek and look around my room to see Armin standing there.I was so happy to see him.He walked over to him and cupped my cheek that Mikasa just slapped."Y/n are you okay?What were you and Eren doing?"Armin said with a concerned look while looking me in the eyes."I'm okay it just hurts.Me and Eren were just watching a movies and fell asleep I don't know why Mikasa over reacted."I said while looking at Armin.I wanted to kiss him so bad.I leaned in to kiss him then he pulled away while letting go of my cheek.I looked down because one it was really embarrassing and I definitely know Armin is loosing feelings."That's good that your cheek only hurts and I understand." Armin said while looking at me."Well I have to go,love you Y/n bye."He said while hurrying out not even giving to say it back.It was probably a lie tho he probably dosent love me anymore.

I saw Mikasa walk in coming towards me."Eren left,it's just us now."Mikasa says while looking at me.I look her in the eyes"Y/n I'm so sorry,Eren told me what really happen.I should've listened to you I was really stupid and made a big deal out of something so tiny.I love you Y/n"Mikasa says with a face fuller of sadness and regret.She hugged me and I hugged her back"It's okay Mikasa,I would probably freak out if my boyfriend was sleeping another women and I didn't know about it"I saw while rubbing her back"I love you too Mikasa" then I felt her tense up in my arms.Like realized I said when I was taking about if my boyfriend was with another woman.I pulled away from the hug.Her eyes were shot open while zoning out thinking hard in her head."Mikasa?" I say while looking her,she still didn't respond "MIKASA!" I yell at her to get attention back.She jumps and looks at me."Are you okay?" I ask her."Yeah,yeah let's get you ice for your bruise on your cheek." I nod while walking in the kitchen with her.

When we got in the kitchen she grabbed some ice for my bruise while lightly rubbing medication on it.Her hands is really soft.Me and her were close to each other,I was staring at her in the eyes when she noticed and started to stare at me in the eyes.Me and her stay like for that second,Until Mikasa kissed me.I kissed her back.I put down the ice on the counter and rapped my arms around her neck,while deepening our kiss.She put her hands on my waist.She bit my lip asking permission to open my mouth.I opened my mouth and felt her tongue slide in.She picked me up putting my legs around her waist walking to our bedroom.She threw me down on her bed and climbed on top of me."Can I take your clothes off?" She asked while looking at me.I nodded.She pulled my shirt off then my shorts leaving me in my undergarments.She went down towards my neck sucking it and leaving gently bites.Then she found my sensitive spot.She started to suck the skin there.I let out a tiny yelp.She started to suck there harder realizing she found my sensitive spot.Her hands roamed my body.She tugged the top of my underwear signaling me to take it off.I did as she wanted I pulled off my underwear.She then came back up from sucking my neck.She pulled her shirt off along with her bra.She then went down my chest,kissing my collarbone then going down to my boobs.She licked one my nipples while lightly pinching my other one.She started kissing down my stomach down to my thighs.She pulled my legs apart while starting to kiss my inner thigh.I know I was wet.I knew what was fixing to happen next.She looked back up at me looking me in the eyes."Can I?" I nodded.She looked back down at my vagina.She  started to lick my clit.The action made my body try to close my thighs but she pushed my thighs apart.She was good really good,she does it better than Armin ever could.She was now licking my folds then going back to colt and licking is again while lightly sucking on it.I was a moaning mess.After a bit of her doing this I felt a feeling in my stomach.I was fixing to cum."M-Mikasa-" I cut myself with a moan."I know"She said with a low tone.A few seconds later I felt myself cum.Mikasa swallowed all of it.She came back up from in between my legs and kissed me.I flipped her over and starting taking off her pants and underwear off.We both were naked now.I started kissing her again.I pulled away from our kiss "Can I?" I asked while looking at her.She nodded.I went back to making out with her.I brought hand down to her vagina and rubbed her clit with my thumb the action made her arch her back.I slid two of my fingers inside her.I didn't move yet to let her adjust.A few seconds later I started to move my fingers in her.She moaned while I continued to finger her.Some time later she looked at me"I'm fixing to cu-"She was cut off by her cumming on my fingers.

I got off of her and went got us wet towels to clean us up.We both out clothes back on and changed mikasa sheets.I went into the kitchen while Mikasa went to sleep in her bed.While I was drinking a glass of water it hit me.I HAD SEX WITH MY BEST FRIEND.OH NO,WE BOTH HAVE BOYFRIENDS.NO NO NO THIS DIDNT JUST HAPPENED.HOLY SHIT I HAD SEX WITH MY BEST FRIEND AND I LIKED IT! After freaking out mentally and having the urge to walk off a cliff,I calmed myself down and walked back into our room with a ice bag on my cheek.I layer down on my bed while Mikasa was in hers.Trying to sleep while you just made your biggest life regret is hard.After two hours of thinking of what I did I finally fell asleep.

That's the end of this chapter.I wasn't originally going to make Y/n and Mikasa have sex the I was thinking why not for a story twist but don't worry y/n and Eren do get together.This is a slow burn story tho.I hoped you enjoyed it!
