His Best Friend's Sister A Sirius Black X Reader.

Chapter 11: Dont Ever Let Me Go

y/n pov

It's been around a month and a half since I was in the hospital wing. my side neck and arm had a huge scars on them and it still hurt like hell. Sirius was making sure I was ok every five minutes. every time I winced slightly he was watching over me like a hawk. it's really cute but sorta annoying. I am laying on his bed while he was doing some weird challenge with James. they were doing some weird workout challenge that they heard some other kids in the school were doing. at the moment they are doing planks. they both had taken off their shirts beforehand and now were both sweating a lot. it was weird. they have been doing this for around twenty minutes. Remus walked in and gave me a confused look. I shrugged and went back to watching this event. Remus sat down next to me. soon enough James yelled

"did it!" 

"That was unessisary," I said

"not really" he shrugged

Sirius came over to me and kissed me on the cheek

"you're a sweaty mess," I said as he ran his hand through his hair

"you love it," he said winking and walking into the bathroom leaving me in shock

"the fuck just happened" I whispered looking at Remus. he shrugged and laughed at me. I rolled my eyes and grabbed my book from Sirius's desk. Remus walked over to his bed and grabbed his book as well. James was about to walk into the common room

"James! shirt!" I yelled as he was about to walk out

"shit your right," he said with a laugh. he threw on his shirt before walking out

"he so knew he didn't have a shirt on," Remus said

"he's trying to impress lily I'm guessing" I added

"Totally" 

Remus left after a little bit. I was getting into my book when someone grabbed it from my hand. I looked up and Sirius was looking at me. 

"Sirius!" I said. he sat down and looked at the book in his hand. I went to grab it but he lifted it higher. I looked at him before rolling my eyes. "your lucky that I will play this game with you" I said before straddling his lap. he grabbed and put the book down on the bed making it so I didn't lose my page before carefully grabbing my waist and flipping me onto my back on the bed. I gasped and wrapped my arms around his neck. he smirked as he moved his hands next to my head. he leaned in and pressed a passionate kiss to my lips. my hands moved up from his neck to his hair and down to his cheeks. he pulled back a little. he tried to catch his breath before I pulled him back down into another kiss. I moved my hands back up to his hair. he pulled back again as we both caught our breath. he leaned back in before passing my lips and going to my neck. I let out a shaky breath as he kissed down my neck sucking and biting at certain points. 

"Sure," I said with my breath still shaky. he looked up at me. "what happens if James sees this"

"that marks?" I nodded "he should expect it," he said with a small smirk. his hands went under my shirt and you can guess what happened after that. I have to say best weekend I've ever had.

I and Sirius were on his bed after cleaning up and changing. I was reading my book while Sirius had his head on my lap watching me. James walked in and looked over at us with a smile until he saw the mark on my neck.

"Sirius! that's my sister!" James yelled

"James! that's my girlfriend!" Sirius yelled back

"agh! why did I allow this to happen!"

I just laughed. 

"it better have been consensual"

"James of course it was. I don't disrespect people like that. who do you think I am"
