Chapter 15

The cab pulled up outside Castle's building, letting Kate and Rick out before driving off. The sexual tension in the cab was intense: between Castle and Beckett, not the cab driver. They made their way into the reception and waited for the elevator to arrive.

"That comment you made earlier makes me think we should make some memories in the storage closet," Castle suggested.

"In your dreams, big fella," Kate chortled.

"Ah, I see. Scared you can't be quiet?" he pestered.

"It's not as much fun as you think," she said suggesting she had experience in that situation.

"You…you weren't lying?" he stuttered before noticing she was playing with him again. "Oh! Very funny. Just for that, I'm not going to tell you an interesting story about Kyra and me…in a parking lot."

Kate knew he was trying to get back at her for her sly remarks during the day. She bit the inside of her cheek trying to contain the curiosity. The elevator doors opened and in they stepped. Castle pushed the correct floor button and once the doors closed, they continued their conversation.

"Whatever happened in the past doesn't bother me, Castle," she lied. "But nice try."

"Actually, I meant to call Gina back. She's been bothering me for weeks about going out to dinner… I might just invite her out tonight."

Castle took out his phone and began scrolling through his contacts. Kate gently picked his phone from his hands and put it in the back of her jeans. He stared at her dumbstruck.

"You know, I happen to know she's not available tonight," she smirked at him. "But I am."

Castle leaned into her, wrapping his arms around her trying to find his phone.

"You're not going to find your phone…it's hidden."

"Is it now?" he asked gripping her behind and squeezing. "So, how am I going to call her without a phone?"

The elevator pinged and doors opened onto a long empty hallway. Kate smiled at Castle, then walked out of the elevator leaving him behind.

"Well I guess you're going to have to figure out a way to get it back," she beckoned.

Castle trailed behind her, taking his keys from his pocket. Kate leaned against the loft door, blocking his path. He stood and looked at her for a minute before asking her to move.

"You're standing in my way," he stated the obvious.

When she didn't say anything, he playfully tried to push her out of the way. But she didn't budge and, in fact, leaned her head against the door.

"Maybe I could join you two," Kate suggested. "You know…have a three-course meal," she said allegorically.

"I don't think she's into that kind of thing."

Castle stepped closer, placing his hands on her hips. Kate ran her hand through her hair refusing to break eye contact as she did so. She began fiddling with the buttons of his shirt, opening the first one.

"Hmm, pity."

"Now, if you don't mind, I've got a phone call to make," he said trying to put the key in the lock.

Kate, still not showing any sign that she was going to move, opened the second button on his shirt. He watched her yearning eyes gleam up at him as she opened a third. He gripped her hips harder and brought his lips to her ear breathing hot air against it.

"I think we need to get inside," he said temptingly into her ear before he started to gently nibble her earlobe.

Kate released a serene moan before Castle flung the door open, them nearly stumbling inside. He swiftly spun them around and shut the door with Kate's body. She grunted harshly when her back slammed against the solid wooden door. Castle forced his lips onto hers effortlessly, their mouth moving in sync.

"Castle…" Kate whispered breathlessly. "What about your mom?"

"Out. With. Friends," he said between breaths.

He latched his lips onto her neck immediately finding her sensitive spot. He slid his hands under the hem of her shirts feeling her soft skin at the ends of his fingertips. Kate made quick work of his shirt, undoing all of the buttons in a matter of seconds. Once his shirt was on the floor, Castle pinned her hands above her head sucking on her pulse point.

"Oh god, Castle," she moaned trying to release her hands so she could touch him.

He pinned her hands harder against the door so she couldn't move. She threw her head back against the door in pleasure while Castle moved down to her collarbone, which is payed extra attention to. She was about to speak, but her breath hitched before she could. He released her hands briefly to remove her shirt, then pinned them back while he kissed his way down the valley between her breasts.

"Kate, what do you want?"

"I want to touch you," she said breathily.

Her knees were weak. They felt like jelly and all because one man had a talented mouth. She wriggled her hands again but failed to escape. He sucked the skin visible just above her bra cup.

"Kate?"

"Hmm?" she responded with her eyes still closed.

Castle stopped everything he was doing and released her hands. Stepping back, she immediately missed his touch. Her eyes opened slowly, perplexed by his actions.

"I better make than call," he said.

"Are you serious right now?" she panted sexually frustrated.

"Consider it payback for all your teasing today," he replied. "But if you admit that you were jealous of my exes, I might reconsider it."

"Like I said before," she said leaning into his ear again. "Make me."

"I'll take that as a no," he said walking towards his office. "Be right back."

Kate was aroused and irritated but was too stubborn to give him what he wanted. Instead, she kicked off her heels and walked to the couch. Castle was convinced she would've given in by now, but boy was he wrong. She slid her trousers down her long legs, then stepped out of them. He couldn't keep his eyes off of her, especially when she lay seductively on the couch in nothing but her bra and underwear.

"Do I look bothered?" she asked.

"No, you don't," he said walking closer to her.

He gave her feet a squeeze, then traced her leg with his finger. He was so enchanted by her beauty that he temporarily forgot what he was doing. The way she smiled at him drove him crazy. He knew she was just as turned on as he was, but the constant foreplay was what they lived for.

"Why bother going to dinner when we've already got the party started here?" Kate asked sitting up and pulling him between her legs by the waist of his jeans.

"Well, because Gina-," he got cut off.

"If you mention her name one more time, I'll be continuing this party by myself," she threatened.

"I'm sorry, why does her name bother you?" he asked knowing exactly the reason.

"Because…" she said as she pulled him closer, "the last thing a girl wants to hear when she's practically naked in front of her man is him saying any name other than her own."

"Just admit you're jealous and we'll let this topic be," he promised, putting his hands on hers and stroking them gently.

He looked at her challengingly waiting for her to bite back. But not this time. Instead of fighting it, she stood up and got in Castle's face.

"I'm jealous of your ex-wives. I was jealous of Sophia Turner. I was jealous of Serena Kaye. I was jealous of Kyra Blaine. I've been jealous of everyone woman you've ever been with." She leaned into his neck and whispered, "Happy?"

"Happy."

She closed her eyes expecting him to devour her, but instead he left her standing in the living room naked. Alone. Dumbstruck, her eyes followed his every move to the kitchen. He perused around the cupboards for chocolate but found nothing. As an alternative, he came back with caramel ice-cream.

"Looks like we're out of chocolate, but I found this," he said showing her the container.

"I told you we should've stopped by the store," she remarked.

"Should I leave and get some?" he falsely offered.

"Oh absolutely," she lied pouncing on him, and pulling him in for a frenzied deep kiss.

Castle gently laid her onto her back on the couch as she ran her hands through his fluffy hair. He held her face in his hands, stroking her cheeks as they kissed. He moved his hands from her face to her back to unfasten her bra. She arched her back allowing him easy access.

"Someone's impatient," he laughed.

"Mmm Castle, shut up," she said muffled in the kiss.

He reached for the ice-cream and took a scoop. She directed his hand to her mouth where she sucked the ice-cream from the spoon. She wiped the excess from the side of her mouth, then licked it off her fingers.

"God, that was hot," he said astounded.

He immediately kissed her to taste the sweetness of the caramel ice-cream. He moaned once the sugar hit his tastebuds. He took a mouthful of ice-cream for himself and kissed down her neck, leaving a sticky trail of ice-cream down it.

"Castle," she gasped, stunned by the cold.

"My bad," he said cleaning up his mess with his tongue.

Kate flipped them over unexpectedly and whispered in his ear, "My turn."

She scooped some ice-cream from the tub with her finger and put it in Castle's mouth. He took his time cleaning it from her finger not once breaking eye contact.

"I can't get enough of you," he confessed tracing his finger along the edge of her black lace panties.

She leaned back down and bit his lip before sitting back up to keep him longing.

"I think we should move this to the bedroom…"

"We should," he said pushing his lower half against her while stroking her inner thighs.

Kate stood up and took hold of his hand leading him to the bedroom. He didn't hesitate to push her down onto the bed and climb on top. She got lost in his ocean blue eyes and caressed his face, running a finger down his lips.

"You've been driving me insane all day," he said. "Consider this a punishment."

He ran his tongue across her right breast. She moaned loudly and brought her body up to his. She put her hands on his butt and pulled it into her pelvis. He moved his mouth onto her other breast giving it the same attention. He could feel himself becoming more aroused and pushed harder against her.

"Take your pants off," Kate ordered breathily.

He jumped up and began fumbling with the button of his trousers. She propped herself up onto her elbows to watch him. She couldn't refrain a chuckle when he revealed his Spiderman boxers.

"Spiderman? Really?" she said kneeling on the side of the bed.

"What? They're cool!" he said convincingly as he brushed a strand of hair behind her ear.

Kate hovered her lips over his distracting him while she slid a hand into his boxers. He gasped at her touch, his eyes practically rolling back into his head. She could feel him panting against her lips yet refused to close the gap. Luckily, Castle couldn't hold back and carefully kissed her. He could feel her hand moving against him and almost lost control.

"Kate…"

"What is it, Rick?"

He was unable to answer her, so she took her hand out of his pants and let the elastic snap back onto him. He inhaled as his abdomen tingled. Kate lay back and pulled him down to her. Caressing his cheek as he looked longingly into her eyes, she smiled up at him.

"Rick?"

"Yeah?"

"I love you."

Those three words triggered a wave of emotions within Castle. He made love to her then and there without a lingering thought in his head. Behind closed doors, they became one. Soulmates are someone not everyone gets a chance to meet in their lifetime. But Castle and Beckett's bond was a rare find and something that could withstand every and any obstacle life put in their way.
