When we met

Late night swim

Yoongi walked over to the pool and felt the water and looked at me as he smiled I could see he was planning something then he ran towards me and dragged me in the pool with him. I shrieked before I hit the water, it was cold at first then it got warmer I went to the surface and seen Yoongi smiling I couldn't help but smile and splashed him with water.
Yoongi:"hahah okay I deserve that"
Me:"yeah you do ahah" I giggled

It was so warm and I jus loved the water and Yoongi came up behind me and grabbed my waist. I jumped a little not knowing he was there bc I was in my own world for a moment.
I turned and smiled at him while hugging him.

Me:"thank you Yoongi" I whisper in his ear he jus tightens his grip then picks me up by my thighs, around his waist in the warm water and I lean back so I can see his face. He smirks at me and I kiss his cheek as a thank you for coming with me tonight since I couldn't sleep. He looks a little shy but I think it's cute and then I kiss his other cheek, he puts me down and we just relax for a bit until we wanna go inside but before we do, I was jus swimming and he goes under water without me knowing and comes up behind me and grabs my thighs I jump and scream as he surfaces while smiling and I splash him.
Me:"you are so mean"
Yoongi:"not even a little bit"
Me:"mhmm" I roll my eyes at him
He goes back under water and I watch him he goes down to my stomach and kisses me up til he reaches the bottom of my bra then surfaces again I look at him shocked.
Yoongi:"what?"
Me:"huh?" I jus stand there with my mouth open I kinda liked it.
He just smiles and kisses In between my bra up to my neck and he sucks on my neck until there's a small mark and a mark on my breast.

I have goosebumps all over my body and I say we should get out and he agrees, he hops out first then helps me out. He then picks up my towel and wraps it around me while kissing my neck again. We turn around and realise RM is standing there watching us.
RM:"what the- what are you two doing?"
Me:"we went for a swim"
RM:"mhm I can see that looks like a bit more than just a swim" he says and walks inside with his jaw clenched and fist tightens, we follow him inside.
Me:"what are you doing up this late anyway"
RM:"I heard a scream, checked ur room and you weren't there so I came down here looking for you and I guess I seen more than I expected to"
Me:"I'm sorry Namjoon" I said looking at him he was death staring Yoongi and you could tell he was very jealous he looked back at me then only realised the hickey on my neck and breast. He was about to run after Yoongi so I stepped in front of him and put my hand on his shoulder.
Me:" plz calm down Joonie" I said giving him a nickname he froze and looked at me and softened up a little bit.
RM:"fine but u are not sleeping next to him tonight"
Me:"okay fine"
RM:"stay with me tonight"  I froze as he said that
Me:"what?"
RM:"you heard me" I looked at Yoongi then back at Joonie
Me:"I- I can't"
RM:"why's that?"
Me:"bc-"
Yoongi:"it's fine y/n.. go" I was shocked he just said that
Me:"but-"
RM:"no buts cmon" he said as he dragged me to his room I walked with him I wasn't mad just surprised.

We walked in his room and I sat on his bed and he just stood there staring at me like this:

It looked like he was thinking but I don't know what it was so I asked.
Me:"why are you staring like that?"
RM:" bc I can and your in you underwear and bra"
I looked down and realised I was still in them so I wrapped my towel around me tighter and I blushed. He smirked at me and sat next to me and told me to go change in his bathroom since he has his own.
His room:

I got my clothes and changed into these:

I walked out of the bathroom and he was waiting in bed with jus his short and no shirt. I sighed and got in bed with him, he looked at me and realised my bruised upper arm with handprints around my arm. He didn't ask but I noticed he tried not to and he just held me around the waist until we fell asleep.
