They'd been working out as a pair for only three months, but Kate had to admit, Castle was impressing her more and more by the day. His agility, strength, and stamina had swiftly improved beyond her expectations. He had proven himself to be a most diligent student, and she was only too happy to teach him hand-to-hand combat and self-defense when it meant close proximity to his sweaty, muscular body on a regular basis.
A tough case that had left them both feeling drained and disheartened was the impetus for the late-night workout, the gym having been deserted hours before. When they took to the mat and began to spar, the only sounds that filled the open space were that of their panting breaths and hearts pounding in their ears. They silently circled each other, both eying the other like prey, both becoming more and more aroused by their predatory dance.
Castle made the first move and regretted it instantly. Kate leveled him, her legs locked around his middle while trapping an arm behind his back. He briefly considered tapping out, but then recalled the evasive maneuver she had taught him just days before. Taking advantage of her momentary complacency, he flipped her with relative ease, placing her flat on her back, her arms pinned and his weight restricting the movement of her lower body.
For her part, Kate could only gasp at the bold move, and if it had been anyone else to pull it on her, she would have been furious. But at that instant, she could only concentrate on the feel of his heated body pressed firmly against her own, their lips practically brushing, every heaving breath shared in the short space between them. She looked into his eyes, hers flicking down to stare at his tempting lips for the briefest of moments before locking onto his gaze again, and what she saw there thrilled her. He was no longer Castle, her sparring partner, but Castle, the man.
They moved in sync then, their mouths fused together, their kiss deep and intoxicating. He abandoned her lips all too soon, but she couldn't complain as his tongue worked down the slope of her neck, gathering the taste of her exertions, humming in pleasure at the flavor of her skin. He slowly made his way down her body, nuzzling at her breasts, nipping at her soft curves with his teeth, finally settling between her thighs, spread so willing for him.
He nudged the waistband of her workout pants down gradually, kissing and worshipping each inch of exposed skin, his lips teasing her damp flesh. Squirming uncontrollably under his ministrations, she almost spoke then, almost begged him to please touch her, but in the end, no words were necessary. When he finally lowered her pants enough to dip his tongue into her, she could only throw her head back and let him work his magic on her body.
She retuned the favor in the shower afterward.
