Hello! This is my first story so please gentle with me.I would really appreciate some constructive criticism and if my story needs some editing or anything else please don't be afraid to point it out. This is a cheating fic with some Eruri but the ending is Ereri. Enjoy

Erwin grunted as he thrusted into Levi, groaning as he picked up pace. Levi groaned, he knew what he was doing was wrong, it was pathetic but because of the pleasure clouding his mind he really didn't care. But doing this always made him guilty, besides Erwin wasn't the one on his mind during sex, instead it was a teal eyed 18 year old brat. Levi and Eren had been together for 3 years,they had met in high school and immediately hit off, he loved Eren with all his heart but Eren wasn't ready for such intimate contact. Of course Levi had needs too but he never complained or whined about it, he thought cheating was the most disrespectful thing to do to your partner and yeah it was hypocritical he knew that but he couldn't turn down Erwin's offer.

From the beginning when he started working at the clothing company Survey Corps. His boss Erwin would always linger his fingers on Levis hand when they shook hands or Erwin would cast glances at him ever now and then, he always knew Erwin's eyes were on him but Erwin never made a move towards him but it changed when one night Levi was working late and Erwin stepped into his office with a deal. What sprouted from a guilty one night stand turned into a 3 month old affair. Levi and Erwin had an understanding and besides he wasn't planning on doing this forever because the day Eren says that he's ready he was gonna call Erwin and stop the affair completely. Erwin groaned loudly as he emptied into Levi and Levi followed after grunting. Erwin pulled out and Levi stood up from the desk, his lower back hurting immensely . After this part Levi became very awkward, guilt filling him once more.

Levi picked up his clothes and pulled on his boxers. He pulled on his shirt buttoning it up and pulling up his pants smoothing them out so it didn't look too suspicious. Erwin followed pulling on his clothes, the silence in the room was deafening neither wanting to acknowledge the elephant in the room. "Eren is waiting for me" Erwin nodded, as much he wanted to keep Levi he knew he loved Eren too much to ever leave him."I'll call you later ok?" Levi walked out of Erwin's office not looking back, making his way to the pulled his phone out of his jacket going through his contacts to call Eren. "Hey Lev, I didn't know you would be this late" Levi felt guilt hit him like a brick but he ignored it"yeah I was just finishing up some papers and documents shitty Erwin wanted to do." Eren giggled causing Levis heart to constrict thinking about never hearing it again."I'm on my way home ok brat?" " ok Levi I love you" Levi smiled making his way out of the elevator to his car"I love you too brat"

Levi arrived ten minutes later making his way to the door"hey brat" Eren was sitting on the couch engrossed in his tv show until Levi acknowledged his presence, Eren smiled bright teal eyes lighting up making Levis heart skip a gave Eren one of his rare smiles and walked towards his boyfriend. Eren hugged Levi and brought him closer, wrapping his legs around his waist and bringing them both onto the couch. Levi laid on Eren putting his head on his chest listening to his heartbeat." How was work?" Eren murmured pulling his fingers through Levis hair. Levi relaxed a bit after Eren started messing with his hair"shitty Eyebrows wanted me to do a lot shit and Shitty glasses was fucking around too much like usual"Eren softly chuckled" if you want I could help you with that stress you're carrying" Levis head popped up eyes opening in surprise.

Eren laughed freely making Levis heart flutter "no not like that you dirty minded old pervert." Levi smirked" what I meant was my friend gave me a lesson in massaging" Levis smirk disappeared almost instantly" did he show you techniques or use them on you?" Levi was extremely possessive, the thought of any one but him touching Eren like that made his blood boil"no he just demonstrated them to me on one of his customers" Levi let out a sigh and nodded his head"ok sounds good brat"Eren smiled and Levi got up reluctantly"go the bed and take off your shirt lying face down" "ok I'm going brat" Levi walked to their bedroom pulling up his shirt and leaving it in the clothes hamper. He laid face down on the bed waiting for Eren to come in. Eren came in with some oil and straddled Levis back immediately working on his muscles.

After half an hour Eren had finished up and Levi felt refreshed and his stress actually did go down . "Wow brat you have pretty good hands" Eren chuckled taking off his shirt"well thank my friend Connie for that" Levi took off his pants putting them in the hamper and pulled on his shorts instead. Levi caught Eren staring at him from the doorway making him smirk"see something you like brat?" Eren shook his head and turned away embarrassed, Levi chuckled and pulled him close making Eren yelp at the sudden movement. He pulled him under the covers and followed under putting his head on Eren's chest. Eren sighed deeply, Levi felt that something was definitely bothering him. Eren tensed up and cleared his throat"I'm sorry Levi I know you want me to I know you have needs but I can't I don't know why it just comes ba-" "Shut up Eren it's okay I understand you don't need to explain it, I'll wait as long as you need me too" Eren smiled and relaxed"thank you Lev" " Don't thank me brat"

Levis heart clenched and his stomach turned seeing Eren so vulnerable. He knew what happened when Eren was younger, and even though the man who broke into his family's house didn't succeed he still traumatized Eren badly making Levi want to track down the son of a bitch and make him pay. He loved Eren more than anything and he knew that his affair was wrong so he knew he had to end it with Erwin Tomorrow. It amazed him on how much Eren trusted him and respected him it made him feel amazing he knewhe couldn't break that trust."I love you Eren goodnight" he rarely used Eren's name, only saying it during serious times but when he did say it, it was worth seeing his face light up when he did." I love you too Levi" Eren pecked him on the lips and sighed contently closing his eyes.

Even though Levi had insomnia Eren's heartbeat seemed to be his cure as he listened closely and closed his eyes letting sleep take him. Levi woke up to cluttering in the kitchen making him realize that Eren was making breakfast. He stood up and immediately went to the bathroom and brushed his teeth. He finished up brushing and walked to the kitchen sneaking up to his boyfriend and wrapping his arms around him .Eren jumped a bit but relaxed into Levis arms"Morning" "Morning brat" Levi murmured into Eren's back as he closed his eyes enjoying the moment. These moments were the ones he treasured the most and even though he would probably never admit it he'd loved and appreciated Eren so much, he honestly didn't know what he would do without him. Levi let go reluctantly and grabbed the coffee pot grabbing a cup as well"today's my last day for working brat then I'm off for my three week vacation" "Yay!You work too much anyways and I'm asking for my vacation too and I know just how to start it off but I'm not sharing." Levi smirked and drank his coffee watching his boyfriend cook breakfast shirtless"I have 1 hour till work brat I'm gonna get ready then I'll get home at 7"

Eren worked in a small cafe not getting the best payment but it was the best job he could get. He was about to go to college on a scholarship that he'd gotten for the University of Chicago. He knew that he wanted to be a doctor from the moment he found out what they did. Levi had already finished college but was leaning more towards being clothing designer or a photographer."Ok sounds good Lev" Levi walked to the bedroom to quickly change into his business suit, today was the last day of his affair and he felt as if a weight had been lifted off his shoulders at just the thought of it. Eren walked in the same time Levi had grabbed a tie, Eren walked over and and grabbed the tie, wrapping it around his boyfriend's neck before tying it. As soon as Eren was done he grabbed the end of Levis tie, pulling him to him and kissed him passionately, resulting in Levi pushing him against the door and grabbing his waist. Eren moaned causing Levis blood to move south.

Eren separated from Levi panting hard as he was"there will be time for that later but you have to work first" Levi growled and quickly pecked Eren's lips. Eren smiled and brought his forehead to Levis" if you make me wait I won't be giving you shit" Levi chuckled and roughly grabbed Eren's behind making Eren jump and yelp." I'll definitely be here brat" Eren fixed Levis suit and pushed him out of their bedroom" go before I make the both of us late for work" "I don't mind" "LEVI!" Levi laughed at Eren's antics. He sat down and quickly ate with Eren sitting next to him at the table even though Eren kept initiating the game footsie.

Levi finished his coffee and thanked Eren for breakfast making his way to the front door."I'll be home soon brat I love you" " I love you too Levi" Eren quickly kissed him and put the car keys in his hand"Bye Lev" Levi smirked and made his way to thecar, a little excited by what his boyfriend was planning to do.

-skip 5 hours-

Levi groaned and looked at the clock, grateful that there was only 2 hours left, he rubbed his face and sighed. He groaned once again when he heard the tell tale scream from his 'friend' Hanji. " Hey shorty I heard you going on vacation" Levi sent a glare her way but it didn't affect her at all. Hanji was the only person who knew about him and Erwin. She hated the fact that he was cheating and still pushed him to end the affair everyday." I can't believe you're leaving me for 3 weeks let me come with youu" Levis frown deepened "no it's just gonna be me and Eren" Hanjis smile and mood disappeared almost instantly"You're gonna end things with Erwin today right?" She was serious and seeing her serious made Levi know that he fucked up" yeah I am" Hanji sighed in relief and smiled"I don't want to see you or Eren get hurt he doesn't deserve that" hearing Eren's name made him smile just a bit. Hanji squealed lightly making very one in the office turn to look at her" Shut up shitty glasses!" Hanji squealed and jumped a bit" he makes you so happy it's amazing I've never seen you smile that much before shorty but I have to go do my thing before I get yelled at see you later" Hanji sang the last part making Levi groan and his frown deepen.

Levi planned to talk to Erwin as soon as possible, but it turned out Erwin had a meeting make him stay out of the office for the entire day but Levi just ended up leaving a little note on his desk simply saying that he wanted it talk to him. Soon enough the clock struck 7 making Levi get up immediately and make his way towards the parking garage. His anticipation got bigger throughout the entire day wondering what Eren was up to. He arrived at the house walking a little faster than walked in seeing candles surrounding the dinner table and Eren putting plates on the table. " wow you're home in record time" Levi smirked and walked towards Eren hugging him"I came home running to make sure you weren't doing anything stupid brat"Eren chuckled and motioned for him to sit down." Well I just cooked and I have to tell you something" Levi sat down and began eating Erens cooking he really did enjoy it when he cooked.

They laughed and talked during dinner just chatting about the most random thing they could come up with, they were extremely comfortable with each other just being to say what was on their minds. "Ok so what did you want to tell me brat?" Eren perked up, he picked up the dishes and put them in the sink and cleared the table. Eren sighed and looked very nervous second guessing his actions "Well I've been planning this for a long while and I'm ready Lev" Eren maneuvered into Levis chair straddling him. Eren slowly unbuttoned Levis shirt slowly undoing each button one by one." I love you more than anything in this world, you make me a better man and make me strive to be a better person and even though I'm usually not sappy I just want to tell
you how much I love you even if words can't express it I love you Levi Ackerman and i want you to make love to me"

Levi was surprised by Eren's behavior but he really didn't mind he loved Eren with everything he had. " Brat I don't want you to feel pressured into the this" Eren shook his head no and Levi held his hips as Eren took off his own shirt. "I'm ready I'm so sure of it, I was just a bit nervous that maybe you wouldn't want to" Levi gave a rare genuine smile"Eren I love you so much you brought so much light into my life and I'm so happy that I met you I love you Eren Jaeger" Eren smiled widely and crashed his lips to Levis.

Levi felt elated with joy, he was finally gonna be the most intimate he could get with the person he loved most. Levi bit Erens bottom lip asking for entrance causing Eren to gasp and Levi to push his tongue into his mouth. Levi growled and picked up Eren, Eren immediately wrapped his legs around him and held on like his life depended on it. Levi pushed Eren into a wall making him moan out loud. Levi felt blood rush south but instead of pulling away like they usually did he ground his hardened length onto Eren's.

Eren pulled away and gasped, making Levi move down to his neck to mark him. He wanted to make sure everyone knew who Eren belonged to. Levi growled and left a big purple hickey on Eren's collarbone"Mine" Eren moaned loudly "Yes yours" Levi kissed Eren once again making them both groan into the kiss. " we are gonna take this slowly brat" Levi pulled away wanting to see Eren's face. Erens collarbone and neck were covered in dark purple hickeys along with some red love bites, his eyes were glazed over with lust his lips bruised from the fierce kissing they did, seeing Eren's face in a such a way made Levi feel so possessive and content it was indescribable.

Levi felt a rush of lust hit him as he looked over Eren again. He growled and picked him off the wall and brought him to the bed in their room. Eren moaned as Levi put him on the back and grabbed Eren's hips roughly,Levi took his time and looked Eren in the face. They stared at each other for the longest time just looking at each other wholly until Levi brought their foreheads together. Levi used his arms as leverage as he lowered himself to kiss Eren, he straddled Eren's hips to have better access to him. Eren dragged his fingernails down Levis back leaving marks that would take a long time to heal. Levi groaned as he felt his nails in his back, he kissed down Eren's chest before reaching his pants zipper.

He looked at Eren for permission , Eren was panting hard but was able to nod a little impatient on what he knew was gonna happen. Just as Levi pulled down his zipper Levis phone rang making them both make noises of disapproval, " you should go answer Lev" Levi grunted and placed a quick kiss on Eren's stomach getting up quickly to answer the stupid phone. Levi was pissed off at the person on the line, they ruined his time with Eren. He roughly picked up his phone and swiped the ID "What?!" "Levi it's Erwin, I need you to come in really quick I need you to look at something then i'll let you enjoy your vacation."

Levi sighed heavily he really didn't want to deal with this shit Erwin wanted." It better be fucking quick" he hung up and threw his phone on the couch and sighed. Suddenly he felt two hands start rubbing his shoulders"it's fine Levi go really quick it's barely 8 anyways I'll be waiting for you at least you have something to look forward to" Eren bit Levis earlobe gently and whispered the words into his smirked and turned to his boyfriend"I'm gonna take the shortest time know to man, fucking shitty eyebrows" Eren burst out laughing and quickly pecked Levi on the lips.

"I'll be waiting" Eren's words held promise and Levi was gonna take the shortest time he could. He quickly pulled on a random shirt from his closet and grabbed his car keys. "Shitty fucking Erwin" he mumbled under his breath. Levi drove to the company's building in a rage. He quickly jumped in the elevator making his way towards Erwin's office.

-Meanwhile-

Eren sat on the bed and sighed contently, he was happy that he was ready to do this with Levi the person he loved more than anyone. Eren got up and pulled on a shirt as much as he hated that they were interrupted he understood that Levi had responsibilities as much as it looked over to the couch immediately noticing Levis phone.

He needed to give Levi the phone in case he took a long time or something happened. Eren quickly grabbed the phone and his car keys making his way over to the extra car they had. He drove looking for the building with the clothing company's logo, two crossed wings one blue one white . He pulled over in the parking garage and made his way towards the elevator ruffling his hair a bit. He arrived at the top floor and he made his way towards Levis office but when he came in there was no one there. He became confused but it died down when he heard yelling coming from Erwin's office in the far left corner.

He didn't really know Erwin he only knew Hanji,Mike and select other people that Levi actually tolerated enough to talk to but the only thing he did know was that Erwin was his boss. He heard more yelling coming from the office but then it died down. He became really curious so he silently walked over to the window. Erwin looked frustrated and Levi looked beyond annoyed. Erwin said something that Eren couldn't hear but Levi nodded his head reluctantly. Erwin turned around and softly kissed Levi.

Levi seemed to get into the kiss and grabbed Erwin's shoulders. Eren looked at the scene in disbelief, his teal eyes wide stood frozen unable to do anything just watching the scene between them."Lev?" Eren whispered it very softly, his voice cracking. Not once did Levi push him Erwin away or look towards the window so Eren concluded that he probably didn't hear him. Eren felt a wave of emotions hit him like truck, the strongest out of each of them were anger betrayal and sadness.

Eren's mind finally processed the scene and he sobbed loudly but put his hands over his mouth to muffle the sound. He turned around and sat against the wall. He gripped his chest, his heart felt as if it was torn in two it was the worst emotional pain he'd ever felt except for the day his mother was announced dead from her cancer 2 days before his seventeenth birthday. He laid his head against the wall and took in a deep shaky breath. He rubbed his chest willing the pain to go away, he closed his eyes trying to block out the images his mind kept creating of Levi and Erwin doing less than honorable things.

Eren sobbed a little more but covered his mouth he couldn't afford to have either of them hear. He bit his lip to try and keep his tears at bay, he was in denial he kept thinking that maybe there was a good explanation for this, maybe the one person he loved and trusted the most didn't just kiss another man. But he really couldn't deny it when the proof was right in front of him, as much as he didn't want to see it. He knew Levi was a good person and he loved him with all his heart, he was just hoping that when after all this was over he wouldn't look at Levi as something he regrets.
