Our Dirty Little Secret

I have never felt so dirty after writing something lmao but I would be lying if I said I didn’t enjoy writing it.  I hope you like it! (also Edmund deserves the world so if you want to read some A+ Edmund imagines/smut I recommend checking out edmundpevensieisbaby on tumblr)

warning: smut below the cut

My fingers were interlocked with his as we walked down the street.  The unforgiving sun was beating down on us as we neared his house.  “This calculus exam is going to kill me,” I groaned.

“That’s why I’m here,” Edmund chuckled, squeezing my hand.  “I’ll teach you all that I know.”

“So we’re actually going to do work this time?” I questioned, raising an eyebrow and causing Edmund to laugh.

“I’ll try my hardest but that skirt you're wearing might make it hard for me to concentrate.”  I felt my face warm at his words.  The skirt I was wearing reached just the middle of my thigh, a bit shorter than I was used to but it was so hot out that I couldn’t help but wear as little clothing as possible.

“It is only Lucy at the house, right?  I don’t want to make a poor first impression with your other siblings.”  Ed and I had only been dating for a few months.  I didn’t want his family to already disapprove of me.

“Actually, Peter just got home from university.  He’s staying for the weekend.”

“You’re joking,” I groaned as we walked up to the front door.  The extra car in the driveway supported Edmund’s claim.  

“I’m home!” Edmund announced as we entered the house.  Lucy was sitting at the kitchen table, eating an apple while scrolling through her phone.  She glanced up, giving a smile and a wave before returning to her phone.  I heard the sound of footsteps approaching us from the hall to our right.  A tall man who seemed to be in his early twenties appeared.  I was taken aback by his attractiveness, his blond hair slightly messy as if he had just woken from a nap, his blue eyes still slightly clouded with sleep.  He ran his fingers through his hair as his eyes landed on me.

“You didn’t tell me you were bringing home a guest,” the man said.

“Well I didn’t know I had to tell you,” Ed replied, releasing my hand to wrap his arm around my waist.  “Pete, this is my girlfriend (y/n).  (Y/n), this is my older brother Peter.”

“Nice to meet you,” I smiled, extending my hand for him to shake.

“It’s a pleasure to meet you as well,” Peter said, shaking my hand as his eyes traced my figure, lingering on my skirt for a moment before flickering back to my (e/c) eyes.  “Ed didn’t tell me he had a girlfriend.”

“We really only just started dating,” I said quickly, feeling my heart race as Peter’s eyes focused on me.  

“If you excuse us, (y/n) and I will be in my room studying,” Ed said as he started to guide me towards his bedroom.

“Are you guys actually going to be studying this time?” Lucy asked from the kitchen table causing me to start blushing.  While I had thought we had been quiet, Lucy’s comment suggested otherwise.  

“Haha very funny,” Edmund said, sticking his tongue out at his little sister.  

“Wow, very mature Ed,” she replied with, rolling her eyes and causing me to chuckle.

“Come on, stop your bickering.  I need you to help me pass this calc exam,” I said, pulling him towards his bedroom door.  I could feel Peter’s eyes watching me as I walked into Ed’s room.  I turned back towards Peter, my eyes catching his causing him to turn away as I closed the door.  My heart was still racing as the door replaced my vision of Peter.  No, this was wrong.  I was with Ed, not Peter.  But there was something about Peter that seemed to draw me towards him.

“You okay (y/n)?” Edmund asked, breaking me from my thoughts.

“Yeah, of course,” I lied, making my way to my boyfriend.  “Now, please for the love of God explain what an integral is,” I said as I pulled out my notebook from my backpack.

Ed and I had been studying for about an hour.  “Does that make sense?” Ed asked as he finished his explanation.

“I think so,” I said, slowly nodding my head.

“Good.  I think we should take a break,” he said while bringing his hand towards my thigh.

“What exactly were you thinking we should do during this break?” I questioned, my voice low as I started to lean in towards him.

“I have a few ideas,” he growled, his hand roughly squeezing my thigh causing me to gasp.  “And a few of them include taking off that pretty little skirt of yours.”  He closed the gap between us that I had already been slowly closing.  The kiss was rough, taking the breath out of me as his hands wandered my body.  Somewhere during the kiss, I moved so that I was straddling him.  I held his face in my hands as I parted my lips, allowing him entrance.  His hands squeezed my ass causing me to let out a small moan.  The sound of someone clearing their throat caused us to pull away quickly.  I looked up to see Peter in the frame of the now opened door.

“Dinner’s ready,” Peter stated through clenched teeth.  He seemed stiffer than before as he looked at the scene in front of him.  I slowly climbed off of Ed, my face now a light pink from a mixture of the make-out session and being caught.  I adjusted my skirt which caught the attention of Peter whose eyes flickered to it.  “Will you be joining us for dinner (y/n)?”

“Oh yes,” I replied quickly, hoping the new conversation would help ease the tension in the room.  Ed got up, walking to my side.

“She’s actually staying the night since I live much closer to school.  That way she can get to school early to study before her exam.”  Peter shifted his weight between his feet as he listened to his brother, occasionally glancing at me.  

“Alright,” he said before turning around and heading back to the kitchen.

“He isn’t mad, is he?” I asked quietly.

“No,” Ed shook his head.  “At least I don’t think so.  I’m not sure what his problem is.  Maybe he’s just stressed.”  He gave a shrug before grabbing my hand and leading me to the kitchen.

“Oh look!  The two lovebirds finally decided to grace us with their presence,” Lucy said as we walked into the kitchen.  Edmund’s parents chuckled at their daughter’s comment.

“You’re just on a streak today of making fun of me,” Edmund said, shaking his head.

“Isn’t that every day?” Peter questioned causing all of us to laugh.  Edmund sat down next to Lucy while I sat across from him next to Peter.

“How’s studying going?” Edmund’s father asked.

“It’s going good.  Edmund’s amazing at teaching math,” I said.  

“Well, it’s easy when the student is so amazing.”  I smiled at Edmund’s words.  His parents smiled as well while Lucy made fake gagging sounds.  This caused her parents to turn to her and ask her about her day.  I half-listened while shoveling food into my mouth, starving after a day of school which included no breaks for lunch.

“Hungry?” Peter questioned, chuckling at his own joke.

“Only a bit,” I replied with, cracking a smile.  “I haven’t eaten all day plus it doesn’t hurt that the food is absolutely delicious.”

“I’ll take that as a compliment.”

“You cooked this?”  My eyes widened in surprise.  At first glance, you wouldn’t think of Peter as a cook.

“My specialty,” he said, a grin on his face.  

“(Y/n),” Edmund’s mother said causing me to turn to her.  “We set up the couch for you to sleep on but if it’s too uncomfortable, I’m sure Susan wouldn’t mind you borrowing her bedroom for the night.”

“The couch is fine,” I replied as everyone had started to clean up.  

“Great!  Edmund, would you clean up your girlfriend’s plate while I show her to the bathroom.”  Edmund nodded, grabbing my plate and walking towards the sink where Lucy was waiting.  I got up from my seat.  As I started to turn to follow Edmund’s mom, I couldn’t help but realize that my ass was level with Peter’s face who was still sitting next to my seat.  I straightened my skirt, trying to pull it down a bit lower to cover as much as possible so Peter didn’t see too much.  I could feel his eyes watch me as I walked away from my seat and towards the hall where the bathroom was.

I laid on the couch, staring up at the ceiling.  It was almost midnight now but I could barely sleep.  All I could think about was Peter.  “Snap out of it,” I mumbled to myself as I turned to my side.  I was with Edmund, not Peter.  But why did Peter make my heart flutter and my stomach do somersaults?  “This isn’t working,” I said, sitting upright.  I ran a hand through my (h/c) locks.  Maybe spending some time with Edmund would help me get my mind off of Peter. 

I slowly got off of the couch, tiptoeing my way towards Edmund’s door.  I paused as I heard what sounded like panting coming from another door.  “(Y/n),” I heard a voice gasp through the wooden door.  I inhaled sharply as I realized it was Peter’s voice.  I slowly opened the door to see Peter laying in bed, his hands wrapped around a very erect cock.  

“Peter?” I questioned, causing him to freeze.  He rushed to cover himself as he started to mumble something.  I felt my heart race as I closed the door behind me, the knot in my stomach becoming more intense with every step I took towards him.  “It’s okay,” I said softly as I crawled into his bed.  Peter let out something between a sigh and a growl as I felt his hands wander my body.

“Fuck (y/n),” he muttered as I allowed my hands to wander his body.  He was completely naked which allowed me to trace over his defined abs and warm skin without any barriers.  “You know, you look a lot more mature than eighteen.”

“Really,” I chuckled as my hands wrapped around his cock causing him to inhale deeply.  “You know, I was actually on my way to see your brother.  I couldn’t get my mind off of you, wondering what it would feel like to have your huge cock stretching out my tight little pussy.  I thought maybe Ed could take my mind off of it,”  I leaned in so that my mouth was right by his ear.  “But maybe acting out my fantasies would be the best way to get over them.”  I gently bit down on his earlobe causing him to let out a low moan.  I had started to slowly move my hand up and down his cock, watching with interest at how Peter reacted to my actions.

He closed his eyes, letting his head fall back on his pillow as I quickened my pace.  He let out a low moan, bucking his hips.  After a few minutes, his hand grabbed my wrist, stopping my hand.  “If you want me to fuck you, you’ll have to stop jerking me off before I cum,” he said.  Although he didn’t say it in any particular way, his words turned me on even more as I rubbed my legs together, wanting any kind of friction.  Peter sensed this as he pinned me to the mattress, his face only inches from mine.

His lips crashed with mine, his tongue ripping open my mouth and exploring it while his hands worked on removing my clothes.  We separated for a moment to take off my shirt before our lips were back together.  I helped take off my shorts and underwear, our kiss being broken up into smaller kisses with gasps of air in between.  He pulled away leaving me both breathless and dizzy.  I watched as he lined himself with me before pushing in.  I let out a loud moan causing him to cover my mouth with his hand.  “We don’t want Edmund to walk in on us now do we,” he said, raising an eyebrow.  I shook my head no.  “That’s a good girl,” he said before slowly rolling his hips.  

My back arched in pleasure, my hands gripping the sheets as Peter quickened the pace.  The bedsprings groaned underneath us as Peter slammed into me over and over again.  He fell onto his forearms, panting into my ear as he quickened his pace even more.  I dug my heels into him, pushing him even deeper.  “You’re so fucking tight,” he said in a half moan.  His lips found my neck causing me to gasp.  Peter sucked and bit down along my neck causing my hands to rake down his bare back, the pleasure becoming too much.

“Peter,” I gasped as he bit down on my neck one last time, almost surely leaving a hickey.  If my mind hadn’t been clouded with lust, I would have chastised him for leaving a love mark on my body, something Edmund was sure to notice.  Instead, it caused me to let out a low moan as my orgasm rippled through me.  My eyes were forced closed as my head flew back my body pressed against Peter’s as I held onto him for dear life.  The pleasure became almost unbearable as Peter quickened the pace, his thrusts becoming more sloppy and desperate as he chased his own orgasm.  

He let out a moan as I felt his warm seed spill into me.  “(Y/n),” he moaned as he thrusted into me sporadically as his orgasm started to slow down.  He slowly got off of me, falling to my side before turning to face me.  He pulled me in for a kiss that was much more gentle than the ones we had shared during our moment of passion.  I rested my head on his chest, listening to his heartbeat as I was slowly lulled to sleep.  The one thing that I could think of as I was pulled into my dreams was that I had just fucked my boyfriend’s brother.
