My first in a series of random one-shots. It goes along with a piece of fanart created by Fania (sciokkyhuddy83 on Twitter and on Instagram). She posted the artwork back on December 20, 2018 and I felt instantly inspired. What especially helped get this little fic going was Fania's caption, which is the first line of the fic.

The beautiful artwork shows Castle in blue tilted back in his chair with his hands clasped on Beckett's back and Beckett in purple pressing her head to his with one hand holding onto him. Both of their faces look determined, like one of their classic foreplay fights is about to happen. This fic had a mind of its own and took me into territory that I did not see coming. Fics do that sometimes.

Anything For Her

"You know that I hate you, right Castle?"

"But you also love me."

"Don't use our love to soften me. I'm infuriated with you."

"I did nothing wrong."

"Selling your Ferrari without discussing it with me is so wrong."

"But it's for the babies. I thought you would be pleased I made such a sacrifice for them. They come first, and we needed a new family vehicle."

She softens a little, whispering, "I'm grateful to have such a thoughtful father for my children. But...the Ferrari..." Her voice returns to normal volume: "You have money. You could've kept it."

"And how often do you think we'll use it once the twins are here? Assuming I still have money in the distant future, we can always buy another."

She tugs his earlobe hard. "OW OW...apples, Beckett!"

"The memories we made in...on...that car..." She lets go of his ear.

He sort of tries not to smirk. "I knew that's what this was about."

She nearly looks like a deer in headlights. "What?"

"That car got you so hot and fired up." His deep voice sends pulses to her core. "It was an aphrodisiac for you. Driving it and watching me drive it...the way you felt from that, from the roar of the engine..." His fingers sneak under her shirt. "You wanted me every time we used that car. And you showed me...sometimes more than once."

How did he take her breath away so quickly? Somehow she recovers and replies, "I'm surprised you could sell it knowing how special it is to me...to us."

"We can always make new memories, Kate. Down the line in a new Ferrari."

"You could buy it back."

His hands stop roaming. "What?"

"Buy. It. Back." Her voice is back to sounding angry and authoritative. "Buy our Ferrari back. Make your hormonal wife happy. Isn't that how pregnancy works?"

"I uhh suppose I could..." He really doesn't like the wrath of hormonal Beckett, and knowing her, she'll hold this over him for the rest of the pregnancy. Probably longer.

Her voice turns seductive. "You do that for me, and I will make you happy." She kisses the spot right under his left earlobe. "Where's your phone?" She begins looking around.

"Woah, you mean right now?"

"Damn right I do."

He reaches into his pocket to grab his smartphone, searches in his Call Log for the car dealer, and makes the call. Both of them look anxious when he asks if their Ferrari is still there. Once Rick breathes a sigh of relief and says, "Oh that's great," Kate pulls away and removes her shirt, revealing her navy blue bra to him. He stutters over his next words but manages to set things up to buy the Ferrari back. As he's ending the call with his final remarks, she's pulling down her pants.

Setting his phone down on his desk, he scolds her, "You can't undress in front of me when I'm trying to talk to someone." She tosses her pants aside along with her socks. She ignores his statement and says, "So it's definite, right? We're getting the Ferrari back?"

He waggles his eyebrows excitedly. "Yes." He adores her huge smile that's making her whole face glow.

"The minute we have it back, I'm driving you somewhere, babe. And I promise we'll still use it plenty once the babies are here. Maybe not much during their first few years, but we will take some drives and some weekend or overnight trips."

"Perfect. Now...you said something about making me happy." "Mmhmm," she moans. She starts unbuttoning his shirt as his hands glide over her thighs and hips. "Still wearing sexy underwear, I see."

"Maternity underwear can be sexy." She pulls his shirt open, and he leans forward to help her remove it. "Mmm much better. Shall we move this to the bed?"

"Why bother when we have a comfortable couch right here," he wonders.

"Mmmm good idea. Need to use different rooms while we can before the place is overrun with children."

"I agree," he states.

Their lips finally meet, and she takes his breath away.

This is an AU where they have the twins BEFORE Lily.
