Mark Fischbach and I (x reader)

Trampoline

An: this story involves cheating, you've been warned.

*knock knock* I heard on my door as I was just getting out of the shower. I smiled at the sound of the knocking knowing it was my boyfriend Ryan. Me and Ryan have been dating for about 5 months now he's a pretty amazing guy.

I answered the door with a towel wrapped around me, I wasn't expecting anyone else besides Ryan. When I opened the door I saw Ryan with his dorky cute smile on his face followed by two other smiles from Matt and Mark. Ryan leaned in and kissed with a smile as he said "sorry to interrupt your shower" I told him it was fine and made my way to my bed room to get dressed.

I drank way too much energy drinks last night I looked over in Ryan's direction who was helping himself to a glass of water as I asked "Do you know where the washroom is?" Ryan took a sip of his glass of water and said "up the stairs down at the very end of the hall."

I made my way upstairs as I looked at the end of the hallway noticing the bathroom, I started to walk down the hall as I noticed a door that was slightly opened. I couldn't help it as my curiosity kicked in and I looked in to see Ryan's girlfriend half naked looking for something to wear. It was wrong to stand there and admire her body but she looked so perfect, I envy Ryan for having such a beautiful and talented girlfriend, she's any mans dream.

She always dressed in the most flattering clothes to compliment her figure, her hair looked amazing even if it wasn't tamed, her smile made me melt, and her eyes were like looking into a deep blue sea and the best part about it was her passion for video games. Sometimes I feel like we are having a moment but I snap myself out of it I know it's wrong and I would never want to hurt my best friend.

I snapped back into reality when she sharply turned around, I ran down the hall to the bathroom hoping she didn't notice me.

I was in the process of organizing all of my papers and stuff that I had in a huge pile over by my laptop desk as Matt said "We're running to the store did you wanna come?" I shook my head no because I was busy. They left and I continued minding my own business when I heard someone marching down the stairs who was still here?

Mark turned the corner and noticed me sitting on the floor with papers all around me "Where'd everyone go?" He asked while looking on the floor, I continued ignoring the awkward tension between us as I replied "They went to the store, I figured you were with them."

Mark sat down on the floor in front of me to help me "is this any good?" He asked while holding up a old letter from college, I looked up at him not realizing I made eyes contact with him and replied "no."

I tried to be nice and help her out organizing and I was doing so when she said "I seen you watching me through my door earlier Mark." I instantly froze as my heart started beating faster shit.

I stared at my hands in my lap as I said "I'm so sorry..I just-you're so beautiful I couldn't help myself.." My face was boiling hot as I looked up at her to see she was red in the face too, she stood up to walk away and replied "No need to apologize, I didn't say I didn't like it." I was really confused and afraid, but I was also relieved.

I looked at her to notice she was making her way to her backyard, I followed not really know what to say or do. When I laid eyes on her in the backyard she was jumping up and down on a trampoline in her yard, I didn't even know she had one, I stood there for a moment before she said "Are you coming or what?" I couldn't deny her as I made my way to the trampoline.

I slid off my shoes and hopped on the trampoline, she didn't say anything to me she just kept jumping up and down, I just jumped with her. I couldn't help but notice her breasts popping out of her shirt but I tried my best to pretend I saw nothing.

After a few minutes of jumping around everywhere and laughing we both plopped down on the trampoline leaving both of us laying on our backs next to each other.

I was trying so hard to stall, Mark was so irresistible and when I noticed him watching me it really turned me on, I know it's so wrong but I just can't contain myself.

I was laying next to Mark on the trampoline as he asked "so what was the point of this?" Followed by a laugh, I looked over at him and said "I just wanted to be a little playful is all." He didn't notice I was starting at him as he bit his lip, he turned on his side to now become face to face with me.

Looking into his soft brown eyes I sighed as he said "this is so wrong" as his face got closer to mine, I could feel a mixture of butterflies and guilt forming in my stomach, this was wrong but it felt so right. Before Mark could slowly get closer to me I rushed in and kissed him on the lips as hard as I could, this felt amazing because I've always wanted to kiss him like this.

We continued making out as the sun started to set, "are you sure this is okay?" Mark asked I jumped on top of him and started kissing him hard hoping he'd take that as a yes. I could tell he felt just as bad as I did but we couldn't control ourselves due to all of this sexual tension.

Mark rolled over on top of me and said "You're honestly so beautiful you know that?" I blushed as I kissed him hard, I felt his hand slide up my shirt and play with my already very erect nipple causing me to moan a little, I loved the feeling of his tough hands feeling my soft skin.

He slowly started to take off my shorts as my breathing increased, the sun was just about gone down as I started unbuttoning his flannel and said "Your body is so sexy mmm" we didn't want to get completely naked because we were outside.

I reached my hand down to his crotch and started stroking it through his pants as he unzipped his pants exposing his erection, I felt my lower region throb as his erection poked against my panties, I've been dying to know how big he was and how he felt inside me.

He pushed my panties aside and slowly pushed himself inside me as I moaned, he leaned into my ear and whispered "it sounds like someone hasn't been pleasured in a while" I bit my lip as he started thrusting in and out of me faster and faster. The trampoline started to creek the harder he thrusted, I was also trying my best not to moan too loud because I didn't want to get caught.

Ryan did cross my mind a little, but now what's done is done, the damage is already done. Mark continued thrusting hard as I was about to cum, I pulled him close and whispered in his ear "I'm gonna cum!" With that he sped up even more causing us to finish almost at the same time, we tried to keep quiet as we reached our climax's.

I heard The door to Matt's car slam from the front of the house as I jumped up quickly and rushed to put my shorts back on "come on!" I said to Mark as we adjusted ourselves and such and ran into the back door out of breath, my legs were wobbling as I collapsed to the floor where my papers were and Mark sat in front of me to "help."

"What we're you two doing?" Ryan asked as he walked into the living room, I looked over at Mark and said "Just organizing some stuff" Mark licked his lips while looking at me as Ryan said "Give yourself a break from organizing and stuff, come on guys lets watch a movie or something" Mark and I obeyed what he said as we got up, my legs still feeling like jello I made my way to the kitchen where the boys were as Ryan came over and kissed me on the lips, I looked down as I remembered what just happened and glanced over at Mark as his jaw tightened in jealousy. I'll tell him someday I thought.
