The look on Chris's face said it all. He wasn't expecting to walk in on his best friend laying on top of his little sister. Let alone have both of them be half naked.

" What the hell is going on!?" Chris yelled as he looked at both you and Sebastian in horror." Chris, I can explain." You said as Sebastian pushed himself off of you." Well someone better." You covered your chest with your shirt, suddenly feeling your cheeks turn red from being exposed like this in front of your brother, and Seb. Seb grabbed his shirt and stood up walking over to Chris and taking his arm, he pulled him out of the room so you could redress.

" What the actual fuck did you do?" Chris asked Seb as he paced the kitchen." Chris, can you let me explain?" Seb asked, looking at his worried friend. Chris stopped and looked over at him." Yes, you can." Seb took a deep breath before trying to explain what had happened before Chris walked in on them.

You walked into the kitchen to see Sebastian standing on one side of the kitchen and Chris across from him. Chris was pinching the bridge of his nose as Sebastian talked." Well yes I'm mad. Wouldn't you be if you walked in on your little sister and best friend fucking on her living room floor?" Sebastian looked at the floor, obviously ashamed of what was happening." I can't tell you or Y/N how to live your lives but for god sake Sebastian, why her?" You walk in before Sebastian had time to answer. You stood next to Sebastian as Chris looked at both of you." What was that?" Chris asked you." I don't know." You whispered." I need better then I don't know." "And what if I don't have an answer for you? I don't question you or get mad when you sleep with every girl you take home." You snapped at him. Your worlds shocked him at first but then his surprise turned to anger." I'm trying to protect you." "From what?" He shook his head and looked away from you and Seb." How long have you too, have you?" Chris asked, motioning towards you and Seb." No, we haven't or aren't." Seb answered." You mean this all started tonight?" Chris asked, looking back at you and Seb. You nodded slowly.

" Fuck." Chris whispered." How long have you too been hanging out or did that start tonight too?" Seb sighed and looked over at you." No don't look at her, answer the question." Seb glared over at Chris before answering." No, actually. We've been friends for along time." Chris looked hurt." And neither of you told me?" "Why would we have when we knew you would have reacted like this?" Chris looked away as he turned red. The room fell silent as the three of you stood in the kitchen. You could feel the anger radiating off of Chris as you watched him run his hand over his face and through his hair.

" Mom wouldn't be happy." He started." No, don't bring her into this. I have just as much dirt on you as you do me." You started." So if you want to humiliate me and ruin the image of me to her then go ahead, I've had enough of being the perfect child." Chris looked back over at you to see tears running down your face." I'm sorry." He finely said." Save it for later, right now I just want you to leave." He huffed but didn't move." And what about him?" Chris asked pointing to Sebastian." She asked you to leave." Seb said, just as mad as you were." Can it." Chris said back." Hey knock it off, both of you." You yelled, putting a hand on Seb's chest when he stood up from the counter he was leaning on." Just go, please." Chris did as told this time and left the room. You looked up at Seb as you heard the front door open then slam shut.

You instantly wrapped your arms around him and hugged him, crying into his chest." This is all my fault." You said in-between sobs." No it's not, I shouldn't have come in the first place." You looked up at him, teary eyed." I'm so so sorry, I ruined your friendship with Chris, I might have even ruined mine with him." You sobbed." Stop." Seb told you, bringing his hands up and cupping your face." He overreacted, I'm sure everything is going to be alright." You shook your head as more tears fell down your face." I feel like such a bitch." You wined before hugging him again. He hugged you back, running his hand up and down your back." I shouldn't have kissed you." Seb pulled away from the hug and looked down at you, a suddenly very stern look on his face." What?" You asked, looking up into his deep blue eyes." Why would you say that?" You frowned." Say what?" "That you shouldn't have kissed me." You shrugged." Because then all this wouldn't have happened." Before you could go on Seb took your face in hand and pressed his lips to yours roughly, making you moan almost a little to easily." Don't ever say that again." Seb told you after pulling back from you. You nodded before kissing him again.

" I should go." Seb suddenly said, pulling away from your heavenly kiss." I don't want you to." You begged, holding onto him tighter." You heard what Chris said-" " I don't give a fuck!" You say." He has his own opinion, and yes I am his little sister but at this point I don't care what he thinks." Seb took your face in his hands, looking you in the eyes." I don't want to leave either, but I don't want to make things worse." You felt tears slide down the sides of your face as those words left his lips." You couldn't possibly make things worse." He shook his head and pulled his hands away from your face." I can't do this to you Y/N, I just can't." He took a step away from you, letting your arms fall off of him to your sides." What are you talking about?" You asked as more tears threatened to spill from your eyes." I'm not going to ruin your relationship with your brother just because I want you."

Your chest felt heavy all of a sudden." You want me?" He looked at the ground and slowly nodded." I do, I really do." You weren't sure how to react to what he said. You had wanted Sebastian for so long you couldn't remember a time you didn't, but you always thought it was one sided. Which why wouldn't you have? He was so much older then you and his bestfriends little sister, there was no reason for him to want you, so you thought." I want you too." You whispered. His eyes shot up in search of yours." You really think I would have kissed you for no reason did you?" He smiled slightly as you took a step closer to him." Chris is a jerk sometimes, he can't handle the fact that I'm not his little sister anymore. He hates that he can't control my every move or thought, it drives him nuts to see me having fun without him, and with his bestfriends non the less." You took Sebastian's hand and squeezed it lightly." I'm sorry for how tonight went." Sebastian spoke up." It could have gone worse." He agreed and took your other hand in his." Can we still be friends after everything?" Seb asked. You nodded." I was hopping for more then friends but if you just want to be friends-" " That's not what I meant." He quickly corrected himself." I don't want what happened tonight to affect our relationship." You reached up and placed your hand on the side of his face." It wont, I promise." He pressed his lips to yours before taking your hips and pulling you closer to him.

Your kiss quickly heated up and you soon found yourself sitting on the kitchen counter, your legs around Sebastians waist as he went to pulled your shirt off. You pulled back from him once he pulled up the corners of your shirt." Bedroom maybe?" He smiled and picked you up, walking both of you out of the room. You giggled and draped your arms around his neck. He walked into your room and laid you down on your bed before pulling his shirt off. You could and would never get tired of seeing him shirtless, he was perfect from top to bottom, and he was all yours. He helped you pulled your shirt off again before noticing you hadn't put your bra back on." You're no good for me." He told you as he looked down at you." You're still here though." He smiled and took your face in his hands." And I'm not going anywhere." You gladly excepted his lips as he pushed you back on the mattress before getting on top of you.

It hadn't been long since you had had him on you but it felt like forever to you. He was slow first. Teasing you and getting to know each other's rhythms, it was heaven. After all clothing had been removed all that was left was you and Sebastian, skin on skin and nothing else. No barriers between you both fiscally and mentally. He made you feel more alive then anyone ever had, in every touch, kiss, and breath he made you felt every ounce of his love towards you. You both collapsed on the bed next to each other, breathing heavily as you felt the sudden soreness spreading through your body's." You've ruined me for other men Seb." You told him as you looking over to the handsome man next to you." That was my whole plan." He smiled back." Chris is going to kill us you know that right?" You said as he pulled you into his arms." I could care less about him right now." He said as you snuggled up against his chest." You're on birth control right?" Seb suddenly asked making you laugh." Yes, you don't have to worry about a mini you running around any times soon." He sighed and rested his head on top of your." Not that I wouldn't mind that at all." You smiled and let your mind wonder into a state of bliss. You didn't want to focus on the things that could happen after what you had just done or the possibility that you could get pregnant, you really didn't care if Sebastian didn't. So there you were, laying in your bed with your best friend turned lover holding you tight. You could think of anywhere you would rather be.

So the ending kind of sucks, sorry about that.
