I've given Y/N a last name in this fic ( Hastings )
Y/N POV I just woke up and finished getting ready for work at the firehouse. I was just about to leave the house when Jason my BFF since the second grade texted me saying he was finally in town with Nick and was going to drop by the firehouse around lunch to see me for awhile. I get in my car and head off to the firehouse. I walk up to the firehouse and see Kelly sitting in his chair at the squad table, I walk up to him and him a kiss on the cheek. "Hey baby" I say while I take a sip of his coffee. He looks at me and doesn't say anything.
"What?" I say looking at him closely.
He picks up his coffee and says "leave my coffee alone" with a little smirk on his face.
I continue to walk into the firehouse and put my things away. Then I head to the kitchen and grab my own coffee and sit at the table with Gabbie. When the buzzer goes off and we have to head out for a call.
Time skip – Firehouse, Lunchtime.
We just pulled up to the firehouse when I see Jason walking up to the firehouse. I smile and head over to him. However, what I don't see is Kelly eyeing me and Jason.
"Hey beautiful, you ok?" Jason says while I start to hug him.
KELLY'S POV
"Hey Gabbie, do you know who that is with Y/N?" I wonder.
She looks at them and shakes her head "No, I don't know who that is" and then she headed off inside the firehouse. I followed her inside, looking back at them.
Y/N POV
"Ive missed you so much. I'm so glad you're here" I say to Jason while giving him the biggest hug in the world.
"Oh, baby. I missed you too. Ive missed having my other Hastings around." Jason says
We break apart our hug and head into the firehouse. "Hey guys. This is my best friend Jason. He is currently in town for his birthday so lets be nice" I say while walking over to get 2 bottle of water. One by one people introduce themselves to Jason, however I see Kelly sitting back just staring at him. So I decided to walk over to him.
"Hey baby" I say while putting my hands on his shoulders. "You ok?"
"What, yeah I'm ok." He says while getting up on his feet and walked over to Jason.
"Kelly" he puts his hand out. I could tell by Jason face he knew who he was and he was already judging him.
"Jason, its nice to meet you. I've heard a lot about you." Kelly was taken back by that and just nods and walks away. Once Kelly left Jason spoke up. "I'm not the only one for thought that interaction was weird"
I slowly walk over to him "Yeah, something is definitely up with him today"
Time skip – Nighttime, Kelly's apartment.
After work me and Kelly headed back to his apartment for then night and I'm on a mission to find out why Kelly was acting all mighty while Jason was here today. While we was on the couch in decided to bring it up.
"Hey, what was up with you today" I say will taking a sip of my beer.
"Nothing" he says while not looking at me.
"Seriously Kelly. What's going on" I say a little too loudly.
He looks my in the eyes and he breaks. "Really. Jason just kept looking at you today. Like you was his."
It's now starting to register in my head. "OMG! Jealousy isn't cute on you" I say while standing up from the couch.
"I'm not jealous Y/N" I say.
"First of all, you shouldn't be because there isn't anything to be jealous of. Jason is gay, he also happens to be married to my brother." I say while smiling. Kelly just nods. "Oh" he says while smiling and standing up from the couch.
He slowly walks over to me and gives me a loving, passionate kiss and slowly starts to walk me slowly down the hallway to his bedroom. His lips started to go down my neck and my heart started to get faster. My legs hit the bed and I fall down and Kelly climbs on top of me.
"Do you still want to try" Kelly says while kissing my neck again.
"Yeah" I say out of breath. Kelly starts to remove my shirt and I start to reach for the hem of his to pull it over his head. Next things next we were both naked kissing. Kelly get in between my legs and starts to line himself up with my entrance. He slowly pushes in and we both moan in pleasure. Kelly starts to speed up while kissing me down the next while leaving marks as he goes. I start to reach my climax and I know Kelly is too.
"I... I'm gonna" I say while out of breath.
"Me too baby" Kelly says while getting faster. We both hit the limit and release ourselves. Kelly pulls out and lays next to me. "Think we did it this time?" He asks while I'm still trying to catch my breath.
