So this came from a story that apparently has gone missing. I wrote this to maybe help those people who are looking for the original. I'm not trying to replace it or claim this as the original.
If you know any story where Kate is wearing Josh's shirt let me know or go on tumblr and tell Alex on castlefanfics.
But either way I hope you enjoy this little story.
He doesn't think this is a good idea anymore. He did ten minutes ago at his loft when the idea came to him. But now he wants to turn around, go back home and watch by himself. Maybe regale her on his Ghostbusters experience tomorrow at the precinct. But he's here at her building so he might as well carry out these stupid plans.
When he gets to her floor he's immediately hit with the smell of clean clothes. Must be laundry week for one of the tenants.
He knocks on her door only to find it open a crack. He poked his head inside to find Kate in her dining room with a laundry basket on the table, folding clothes. But that wasn't the important part. She doesn't have a shirt on!
He quickly looked away, respectful of her privacy and knocked loudly on her door. When she answered it she was wearing a blue sweater that was way too large for her.
"Hey."
"Hey."
"Come in. What's up Castle?"
He doesn't like how big the sweater fits her. It obviously doesn't belong to her. And based on what it says he has a pretty good idea of who it belongs to.
Knock knock
Who's there?
Doctor
Doctor who?
Haha!
Ha-ha. Funny. Pompous ass.
"What's wrong?" She asked him after he didn't speak.
"Who's sweater is that?"
Kate looked down at her sweater to see why he would ask because when he knocked she just threw on anything. But now that she sees it she knows why he asked.
Shit.
Shit. Shit. Shit.
"It's mine."
"No it's not. To whom does it belong?"
"Castle what makes you think you can come over here and-"
"I can tell it's not yours. It's ten sizes too big. It comes five inches past your wrist and five past your waist. And you don't even like Doctor Who. It's an ex-boyfriends?"
"Yes," she found herself saying. Although she's afraid of where this might go. She can tell he's angry, but this is strangely arousing.
"Josh's?"
"Yeah."
"Take it off."
"Excuse me?"
"Take it off. Throw it away. Better yet, burn it."
Kate looked at him incredulously. Was he serious?
"Castle you have no right to tell me what I can and can't wear. Especially not in my own apartment." She can feel her anger rising.
"I know- I just..." Oh. He's jealous. Castle is jealous that she's wearing another mans shirt. "I never liked him and to know that you kept his shirt..."
"Okay. I'll change it."
"No you shouldn't have to. I have nothing-"
"Castle," she said firmly to get his attention. "I'll change it."
She was able to suppress her smile until she was alone in her bedroom. Jealous Castle is adorable. It makes her heart beat a little faster being reminded of his feelings. He still cares and he's still waiting for her so the least she could do is not wear an ex-boyfriends clothes around him.
When she went into her drawers she saw that the only shirts she had were tank tops, which she isn't going to wear in front if him because they don't cover her surgical scars.
"Hey Castle," she began when she walked back into the living room. "I just put all my shirts in the wash."
"Here," he said shedding his coat and taking off the grey jacket he had on underneath. "Take this. Just until your clothes are done."
She could've just put on a button up from the closet but...yeah.
"Thank you," she said meeting his eyes. They were impossibly blue tonight with a hint of desire floating through them.
"No problem."
Kate quickly changed into his jacket- that was too big for her but she isn't complaining.
"So Castle. Why exactly did you come over?" She asked when she stepped back into the living area.
When Castle saw Beckett in his sweatshirt he nearly had a heart attack. He already thought she was gorgeous but seeing her in his clothes was doing all kinds of things to his body. God, she's beautiful. Her hair a curly mess from her braid, tight yoga pants, and his sweatshirt. Damn.
"I came- I came because I thought you might wanna...watch Ghost...busters."
"Oh."
"I mean. You're busy so I can come back another time."
She just nodded and bit her lip. Does she not have any idea what she does to him?
"I actually have impromptu plans with Lanie later."
"Oh okay. Yeah."
"But thank you. Maybe we can do it another time?"
"Yes. Definitely."
"Do you want your jacket back?"
"No keep it. And burn that other thing. You're not allowed to wear anyone else's clothing."
Kate raised her eyebrow at him, questioningly. "And what if I do?"
Castle just came and stood incredibly close to her. Making her walk herself backwards into her front door. When her back hit the front door he leaned down next to her ear and whispered "you won't."
She closed her eyes when his warm breath caressed her neck, causing butterflies to erupt in her stomach.
God, she wants him. Badly. And wearing his jacket only intensifies it.
"Goodnight Kate."
"'Night Castle." She seriously doesn't want him to go.
Kate let out a deep breath when Castle left before leaning against her front door, completely unsatisfied.
This is different from my usual work and maybe its a little OOC? Idk let me know what you think!
