I start to wake up and my arm is on the other side of the bed, I feel nothing but just the soft covers on my bed.

I thought Y/N was sleeping with me but I felt stupid knowing he wasn't there.

I still remembered what happened last night, I didn't know what came over me to do... That thing with him, I felt guilty, I felt like I forced him into doing sexual intercourse with me. I felt pretty crappy about it.

But at the same time, I felt glad and relieved for having sex for the first time, to have my virginity took away from Y/N.

I felt free.

I get up and get ready for the day by taking a shower and brushing my teeth, I felt guilt in my stomach, that painful guilt.

Maybe I should fill my stomach up with food to take that pain away.

I fly out my apartment window and start the day off as Supergirl, fighting crime and those who dare try and fight me and hurt others.

I helped get a little girl's cat down from a tree it climbed up on and couldn't get back down.

After crime was dealt with, I fly to the DEO and land on the balcony, walking down the steps and seeing Alex and Winn with Y/N at the wartable.

I join in, I was in Y/N's eyesight as he looked at me, smiling weakly.

I smiled weakly back at him, as we continued talking about the World Killers, especially finding Pestilence and the World Killer hideout.

I had a crinkle in my eye and Alex notices it so she brings me to another room.

"Kara, are you alright?" she asked me very concerned.

"yeah I'm fine, it's just the stress of finding the World Killers, especially after Reign coming back from the dead" I said back, hiding the truth from my sister.

"Kara, you've got a crinkle in your eye, are you sure you're telling the truth? You seemed pretty shy around Y/N which I've never seen you do".

Oh Rao, she might actually find out.

"what? Phfft, I don't know what you're talking about" I say back without thinking.

Alex was about to open her mouth again but an Agent entered the room to tell her she was needed.

"we'll continue this conversation later" she said, making me gulp nervously.

I need to tell Y/N how much I felt about last night, even though I felt guilty about it, I don't regret having sex with him.

I walk back out and happened to bump into Y/N, it was like he was looking for me.

"oh, there you are, I was wondering if you wanted to talk... Please?".

"in here" I drag him to the room I was just in and turn round to speak with him, my cape stops flapping around behind me.

"I uh... Just want to say that... I'm sorry" I say before he could open his mouth.

"for what?" he says back softly.

"for... Making you have sexual intercourse with me, I didn't know what came over me, I was just so desperate to have someone take my virginity away from me" I shyly say to him, my hand on my upper arm.

I was nervous, very nervous and felt awkward.

"hey, you don't need to be sorry, if you're feeling guilty about it then... Don't... I'm not bothered and to be honest, I was thinking about it as well... That's why I was looking around for you, to see if you're ok from last night" he says, his finger was under my chin to make me look at him.

I smile weakly before speaking.

"I was also... Thinking..."

"about us" he interrupts.

I could only smile before pulling myself closer to him, I felt this... Love cursing through me, this feeling I haven't felt since I was with Mon-El.

His face draws closer to mine and we close our eyes, his lips touch mine, giving me a soft and passionate kiss.

"I love you" he says pulling back with a little smile on his face, I haven't heard those words coming from Y/N before, was this really happening right now? Is this how our relationship starts? All because we were supposed to have a one night stand?

A little part of me wanted to stop him, we made a pinky promise not to do anything like this again, but... I wanted to feel in love again, to have a man to trust with my heart, Y/N already earned my trust since the day we became friends; then best friends and now; this.

"I love you too" I say back with a huge grin on my face, pulling him into a kiss.

He pulls back and goes for my neck, softly kissing and pecking it, my breathing were soft but got heavier as he continues to kiss my neck.

My hands travel up his back and I dig my nails into his shoulders softly, moaning in his ear.

I felt waves of pleasure go up my back, as I pin him to the wall near us and start making out with him, his tongue goes down into the cave of my mouth, starting a long, passionate French kiss.

I drive my hands underneath his DEO shirt to feel his hard abs, we continue going down on each other and I was about to start undressing him again, we hear someone clear their throat, making us scramble like scared chickens.

"what were you two doing?" Alex's voice was stern, she didn't sound happy, Winn was behind her, looking over her shoulder to see me and Y/N.

"we were just uh... Talking" Y/N felt very awkward, and out of breath.

"yeah, you both are out of breath talking?".

"uhhh" we both didn't what to say.

"I've got nothing to do about this guys, she-she scares me" Winn says pointing at Alex and looks back at me and Y/N.

I feel my face heating up red, clearly embarrassed about the situation I was now in.

"Kara why did you lie?!" Alex was now even more annoyed.

"I... I didn't know how to tell you" I was fiddling with my cape, feeling awkward and nervous.

"I knew you two were up to something, you both looked at each other like you did something bad or... Wait... Oh no... Oh god, did you, ugh no!" Alex cringed pretty hard, I'm guessing she's now just realised why me and Y/N looked at each other awkwardly earlier on.

"Alex, I promise it won't happen again, at least I didn't do it here with him" Rao this felt very embarrassing to talk about.

"jesus Kara, don't say that!" she says back at me before excusing herself from the room, Winn followed Alex out, leaving me and Y/N alone on the room.

"well... That was awkward" he chuckles awkwardly.

"yeah... Uhhh... Let's uh, agree we forget about that and continue on from there" I say back at him, giving him heart eyes and feeling more relaxed.

"yeah" he gives me a kiss on the lips "let's continue on from here".

(2 weeks later)

Fair to say... The World Killer situation has been dealt with and Y/N has been working with us to stop the World Killers since then.

He was there at the Fortress of the World Killers, he saved Alex's life by jumping into Reign's out of control heat vision which made me go into panic mode when Reign disappeared and me seeing Y/N dying on the floor.

He was rushed to the DEO, and I was so happy he was still alive, but unfortunately he suffered a severe injury, keeping him out of the action for now.

He still works at the DEO, just behind the scenes and everyday, I see him at the wartable, I go to him and greet him with a kiss.

The DEO knows that Supergirl and Agent L/N are dating, J'onn knew how happy I am with Y/N, especially after the whole shakeup with Mon-El being married to another woman (Imra Ardeen) in the future.

I was heartbroken back then, but with Y/N's heart, it fixed the broken pieces in my heart all because I desperately wanted to have sex with a perfect man who happened to be Y/N, my best friend, now my boyfriend.

A one night stand? No... It was more than that... It was just the beginning of something bright... Something... Super.

"morning babe" I fly back into my apartment and see Y/N watching the TV.

"morning sunshine" he said back looking at me after putting his t-shirt on, his hair was damp, guessing he just got out the shower.

"I got you these" I handed him his coffee and Red Roses.

"aww, thank you" he smiles and kisses me on the cheek as I place down the cup container I had my coffee in.

I went to change into casual clothing and come back through as he plants the flowers on the lamp shade, which reminded me when Mon-El did that.

I chuckle at him and walk to him, wrapping my arms around him, as he places down his coffee beside mine.

"I had fun last night" I smile brightly, last night was probably the best night I've ever had in ages, especially after the so called 'one night stand' we had, it felt so good to do it again with him.

"yeah, me too" he plants his lips on mine, starting a passionate kiss.

"so... When do you think I'll be meeting Alura?" he asked pulling back.

"on Friday, so it's in a few days when we'll be going to Argo, you'll love it" I smile.

"let me ask again, you won't have your powers when we're there right?"

"no, Argo orbits a red sun" I say back.

He acknowledges what I say and just as we were about to kiss again, crime appears on the TV, news reporters were recording live.

"well... Guess Supergirl will be needed" he sighs.

"yep" I sigh back before pulling away and using my super speed to change into my suit.

"you are so fast and I love it" he had a big grin on his face.

"I'll see you at work babe" I kiss him on the cheek before flying out to save the day yet again.

"yeah, go get em Supergirl!" I hear him shout out with my super hearing.

All I could do is smile, I love him with all my heart, he's so loving and caring, and funny.

One day... Maybe one day... We're gonna be married...
