DAY 13: Heat

When Rick returned to the bathroom, Kate had turned the jets on again and was letting them soothe her back. Her eyes were closed and her face was relaxed and glowing, from both the Jacuzzi and her orgasm. Steam was still rising from the water, fogging the mirror and window, giving the room a thrilling feeling of wickedness. Kate's breasts were half beneath, half above the water surface, the nipples hardened by the tickling bubbles of the jets, daunting droplets clinging to her skin, teasing him and taking his breath away.

She looked like a goddess to him, and the thought that she was his, that he was allowed to touch her and taste her, made him eager and nervous even after all this time.

He sat down on the edge of the tub, his feet dangling into the water, and her eyes slowly opened. He watched her in amusement, his desire ever growing as her eyes shot from side to side, zooming in and zooming out, focusing on one object, then the next as she scanned the room.

"You're really out of it" he commented with a breathy chuckle and raised the condom wrapper to his teeth to rip it open.

"Come again?" she asked in a daze and his laughter echoed off the bathroom tiles.

"Oh yes, I'll make sure you come again" he leered, but instead of the eye roll he had anticipated at his intentional misunderstanding, she blushed and wetted her lips.

Detective Kate Beckett didn't blush often. Rick lowered the condom to his side.

"Are you alright, Kate?"

His concern only intensified her blush. She rose from the bench and moved over to him, resting her hands on his knees as she looked up at him, her fingers nervously tracing patterns on his skin as she fought for the right words.

For once he couldn't read her expression. It changed too fast; every time he thought he had it figured out, her look shifted completely. He was pretty sure that she wanted to tell him that they should take it slow, that she was blushing and uncomfortable because he basically had blue balls and she thought she couldn't give him what he needed. But the next second she looked like she wanted to eat him up, ride him hard and fast and do things to him that even his writer brain wouldn't dare to imagine. Then she looked dreamy, almost romantic, so full of love that he just wanted to kiss her and hold her in his arms.

He didn't know what to say, only blinked in confusion when she reached out to turn off the jets once more. She swatted the condom wrapper from his hands and moved closer into the v of his legs, and he was rendered completely speechless.

When she then proceeded to bend down and delicately kiss the plump head of his erection, he could only groan.

"Kate…you don't" he gasped as she let her tongue swirl over him, her short nails digging into his thighs just above his knees. "Stop... I can't…" he inarticulately pressed out, but her only response was to take him into her hot perfect little mouth. He was so turned on from watching her come, he knew that it would only be a matter of short minutes if she were to continue her titillating game.

"Mm-mm" she hummed against him and his hands clenched to fists on the edge of the Jacuzzi. She sucked lightly and then pulled away just the tiniest bit, so that her lips brushed against him with every word she spoke. Her eyes languidly swept up to hold his heated gaze. "Let me do this."

Her fingers wandered up the inside of his thighs as she took him into her mouth again and he groaned. She adeptly shielded her teeth from him as she went up and down, sometimes teasingly grazing him to coax a reaction out of him, her clouded eyes all the while locked with his. When she let one of her hands join in and work his shaft, pressing her flat tongue to his head, he gasped and his fingers automatically came up to thread through her hair.

Rick felt the coil inside him tighten and wanted to draw her away from him, but she pumped him faster and the bucking of his hips he had tried hard to suppress until now encouraged her only further, causing her to moan and hum around him as her eyes fluttered shut.

"Kate!" he grunted as she sucked hard, and then he finally, finally let go and released into her mouth.

She continued to milk him as he thrust into her, barely controlled, until she swallowed every last drop. A breathy, shaky moan was all he was capable of as Kate made her way up his body and out of the tub with sloppy, open-mouthed kisses. She pushed him backwards until she was out of the water, pushing herself forward so she was straddling him, her hands coming up to his neck as she kissed the last of sense out of him.

His hands wrapped around her slim waist, holding her tightly to him, his tongue invading her mouth, tasting salty remnants of himself and a sweetness that was uniquely hers. She shivered, goose bumps breaking out on her skin, not sure herself whether they were caused by his hands or by the cold air, now that the hot water from the tub was running down her body and evaporating.

Rick noticed it, always the observant writer, and pulled away. Guiding her gently from his lap, he helped her up on shaky legs and together they wrapped themselves into fluffy bathrobes. Kate pressed a soft kiss to his lips and they smiled at each other.

He loved that about her, too. She could do dirty, inappropriate things to him in a hot tub, ride him on the kitchen counter and kiss him into desperation, but one genuine smile from her still turned his world upside down. He hoped this would never change.

"I love you" Kate whispered, somehow sensing his suddenly sappy mood. He shook his head and framed her face with his large hands. He wasn't saying "No, you don't", but rather "I don't believe this is really happening". She understood him wordlessly, as always, and leaned up to kiss him again.

When she playfully nipped at his bottom lip, he groaned. Just like that, she could turn him from sentimental to aroused, as if there was a switch only she could flip. Her tongue flicked out to tease him and his hands slipped from her face down her neck straight into her robe, kneading her breasts as he walked her backwards until her back hit the sink. She gasped and their lips parted, his mouth immediately latching on to her neck as she breathed heavily into his ear.

Before she could even open her eyes, her bathrobe was pooling at her feet and she was being lifted onto the counter. His hands and mouth seemed to be everywhere at once, caressing, squeezing, licking, biting and sucking on her skin, sparking an all-consuming fire that made her choke on the humid air. Her own hands weren't idle either, first fisting in his hair, then pulling and tearing at his robe until it joined hers on the floor. The broad planes of his chest seemed to burn beneath her fingertips, the flexing of his muscles under her touch invigorating, empowering.

His hands threaded roughly through her wet hair when his feasting mouth returned to her lips. The sounds they were making seemed barely human and there was an urgency in their movements that Kate only remembered from earlier that day, when they had been joined at last after the longest 13 days of her life.

She clawed at his back and gripped his strong sides so tightly that she was sure there would be bruises afterwards, but he responded by moaning in pleasure into her mouth, so she only held on tighter.

Her hips arched into him, seeking friction, discovering that he was almost ready for her again. She trailed one hand down his taut stomach, but he snatched it midway, brought his other arm around her waist and pulled her from the counter. She gasped in surprise and then her knees almost buckled in anticipation when he gently, but determinedly turned her around and she understood what he was planning.

His lips and teeth met the back of her neck, his fingers brushing her wet mass of hair to one side for easier access, and she bit her lower lip so hard that she was pretty sure she broke the skin. She didn't care, because in her haze of lust she couldn't single out one sensation, it was all a jumbled onslaught of pleasurable pain and painful pleasure.

His tongue trailed down her spine and she moaned loudly, her knuckles white on the counter as she gripped hard to keep from falling. Her back arched and her butt rubbed against his groin, causing him to growl and bring his hands up to her breast to distract himself. He squeezed them and pressed her into the counter, knocking all breath out of her as her heated, wet center came into contact with the cold marble.

"Rick…"she whimpered and one of his hands skated over her ribcage and down to her stomach. "Please" she moaned as his fingers only teased her hipbone, and he bit into her shoulder so that she yelped in tremulous surprise.

"Open your eyes" he said, his voice gruff with need and passion. "Watch yourself."

And then he waited until her eyes shot open and met his in the mirror before he let his hand slide down and over her clit and right into her heat.

Her eyes flew to his hand in the mirror of their own volition and she watched herself tremble and grind back against him and into his palm until she came, so hard and powerful that her eyes squeezed closed.

He kept slowly stroking her and only slid his hand away when her eyelids fluttered open again. His wet fingers glided down her thigh, lifting her leg up and wrapping it around his, spreading her to his liking as she continued to shake and twitch in his arms.

Gently he pushed her upper body forward, bending her until her forearms were resting on the counter so she could balance herself.

Snaking his hand around to her clit once more, he slowly pushed into her from behind, both of them moaning and stopping for a second to adjust to the feeling.

When she pushed slightly back into him, he pulled away and started a rhythm of thrusts that soon bordered on frantic, his fingers rubbing tight circles around her clit. The exciting angle made him hit all the right spots inside her, while his hand could play with her freely and without restriction.

As their breaths became more shallow, Rick slowed down his speed and guided her leg back down to the ground, the change of position making her gasp and then push her hips back to meet every one of his thrusts. She didn't even notice his other hand slide up until he pinched her nipple, and the shock and surprise had her clenching around him.

His hips stuttered and he groaned that he was close, thrusting faster when he saw that she unfolded one of her arms from the counter and brought her hand down to meet his at her center. It only took a small touch and a hard push and they were both flying, screaming out their release. Kate sobbed his name as he emptied himself inside her, her muscles spasming around him as wave after delicious wave rolled through her body. They collapsed against the counter and focused on nothing but breathing for a while, their hearts pumping so fast that she could feel it throb in her ribcage.

Kate's eyes opened first and she released a breathy laugh - the condom was mocking them from its place on the edge of the Jacuzzi.
