Reader POV

I was in my room studying for an upcoming test that we had for English literature. I was reading Act 1 Scene 5 of Romeo and Juliet as out teacher had asked us to, when i felt a pair of warm arms hug me from me behind. "Mark, I'm doing some homework." i said. A light hum emitted from his body and i groaned. If he wasn't going to move i might as well move to the bed where it will be comfortable. In my frustration i stood up and pushed him back with my chair, temporarily breaking the hold he had on me. 

i walked over to the bed and laid down, the book clasped around my hand. Mark soon followed laying down on top of me so his head rested on my chest. i moved one hand away from my chest and started softly stroking his hair. i flicked the page of the book, taking in Shakespeare's use of imagery and word choice, absorbing all of the information i could for our upcoming test. Mark, however was getting restless. He wanted something more from me and i had promised him i would. 

Mark was my older brother. It was wrong, the relationship we had with each other was wrong. I had known him for as long as i can remember and i love him. However we love each other more than we should. He is 19 and one year older than me. I would finish school this year and we decided that as long as we couldn't get caught by our parents, as soon as  graduated we would leave and live together. Our relationship was far from brother-sister love. It was more like girlfriend-boyfriend. It was scary when we started going out, we had to be super careful but we didn't mind as long as we were together. He took my virginity last spring and it was the best thing i had ever had. He didn't feel like my brother, he was more than that to me. I felt it.

I had promised him 1 week ago i would have sex with him if he drank water from the dirty lake, it was a promise i didn't think he would keep, until he came home throwing up. He had been sick for a week and i had been taking care of him. Yesterday he got better, but i had been so tired from looking after him that i fell asleep after one kiss. So today he was desperate for me to follow through with my promise.

Mark lifted up my shirt planting butterfly kisses all along my stomach, i placed the book on my nightstand and placed my hands in his hair. he shifted his position to be hovering over me, thighs on either side of my hips. His lips trailed up my chest pulling my shirt off in the process. He went up to my neck, nibbling on the skin. A few small moans erupted from my mouth. "Mark do we have too today, i-" I moaned again "I have work to do, tests to study for" I pleaded. Mark refused to let me escape like last time so he moved down to my bra and started pulling on the straps around my shoulders. He nibbled on the exposed skin of my chest and un-clipped my bra from behind. 

I pulled the blanket i was laying on around my shoulders as i placed my arms on Mark's neck pulling him into a deep kiss. He lovingly placed his hands on my waist, pulling me deeper into the kiss. He pulled my shorts down my legs, taking my underwear with them and pulled off his own, still kissing me. He adjusted my legs as he had done so many times before. He pulled away from the kiss and placed his head on my neck as he pushed into me. We were both too tired for foreplay and even this was enough for me. he continuously pounded into me, earning gasps and moans as he went further. I gripped onto his shoulders as he pushed further into my neck. He would occasionally kiss the skin on my neck as a sign everything was okay, and it was. I felt safe in his embrace, in his love. 

After a few more thrusts i rode out my orgasm, and he followed soon after. He collapsed into my neck, nibbling on the skin as we took deep breaths. I pulled the cover over him and he gripped my waist. He pushed up from the bed to lightly hover over me, and pulled me into a kiss.

However, right as he did that, our mum walked in. As the door opened we opened our eyes to see our mother at the door with her hand over her mouth gasping. We immediately pulled away from each other and stared at her, not wanting to see each other and to search our mum's face for any sign of emotion, disappointment, disgust. Anything.

Eventually, our mother closed her eyes, drew her hand away from her mouth and sighed. She turned around and as she was closing the door she said "Meet your father and I in the kitchen"

We grabbed our clothes and hastily pulled them on, still not looking at each other. We slowly walked down the stairs, Mark leading. We gathered in the kitchen, i pulled a chair out from the table and sat down. Mark lent against the door frame and my mother washed dishes on the kitchen while my dad placed down his newspaper.

Our dad coughed awkwardly ans spoke up "It has come to our attention that you two have a intimate and loving relationship that must have been going on for a while. With this news we have something to tell you that might not make your relationship so forbidden. Y/N is not your biological sister Mark. She never has been and never will be. Her mother was an underage teenage girl that so happened to be at the hospital during my shift. Her pregnancy was the result of a one night stand and her boyfriend at the time did not want a child so early in their relationship. She was considering an abortion and asked me for my thoughts. We had just had you Mark and we did not want you to be lonely. I told her we would look after the child once it was born and we would pay her for her troubles. She agreed and thanked me for not killing the poor child. We still keep in touch with her and show her pictures of you and how you've grown but she does not regret giving you away. It's not that she does not love you, but more she can't raise you how she would have wanted. However this means you two are free to love each other, just please be safe."

Mark and I looked at each other. For 18 years I had lived with him, told i was his sister and i wasn't at all. I loved him, and it was fine to love him. That was all that mattered.

////////////// Sorry for the delay again, and for the terrible ending. Hope you don't mind!\\\\\\\\\\
