Fin grinned as he turned to follow Alex down the hall to her bedroom. He watched her ass and hips sway alluringly and the muscles of her slender back flex as she stretched. Shaking his head, he almost laughed outright because he had never guessed that Alex Cabot would be such a champ.

When he saw the bathroom, he veered off course to give Alex a minute to herself and to splash some water on his face. When he reached the bedroom two minutes later, Alex was lying on her side on top of the sheets, head propped up on one hand. Fin stopped in the doorway, leaning against the frame and admiring the slender curve of her body. Alex took the opportunity to look at the detective. During their first tryst she hadn't had the time to see the whole picture, and she paused now to admire his length and width. It fit with a body that was hard and muscled, ready for action.

Fin saw her looking and gave a sideways smile, walking over to the bed and tossing another couple of condoms on the bedside table before lying down on his back beside her, hands behind his head and looking at the ceiling. He closed his eyes and inhaled deeply.

"So how'd we do?" Alex asked, suddenly slightly off-kilter.

Fin shot her a sideways look of appreciation and a smirk, "Baby girl, you did just fine. Very fine."

Alex smiled and bit her lip, "Do you need a minute?" she asked.

Fin closed his eyes again, "Just one," he replied, reaching over to take her hand and place it on his chest.

Alex nodded and let her fingertips trace small circles over his pecs feeling his steady, constant breathing. Restless, she stood up and walked over to her closet, replacing her heels. Fin opened one eye and watched her bend down to place them in the closet.

"Shit," he breathed. Alex turned around to see him half-hard.

"Already?" she asked, eyebrow raised.

"Can't help it," he shrugged, keeping his eyes on her as he wrapped his fist around his length, "could use a little help."

Alex smiled and returned to the bed, draping herself back over him. She leaned down and kissed him, running her tongue over his lips which he opened obligingly. She could feel his errection pressing into her stomach as they kissed, his fist slowly pumping. She reached down and stilled his hand, pulling it back and placing it instead on he breast. He groaned and kneaded her flesh softly as she kissed down his neck and over his chest. She could feel his breath pick up as she reached his stomach.

"Alex... don't tease," he hissed softly, running his hand through her hair.

Slowly, Alex licked his entire length. Fin exhaled and threw his head back. She sucked gently and his fist tangled in her hair. Swirling her tongue around the head, she inhaled the heady scent of him. His grip on her hair tightened slightly and she kept her hand moving but dropped her mouth back to suck gently on his balls.

"Oh shit," Fin breathed again, pulling her up so she was straddling him.

"No good?" Alex asked, teasingly.

"Too good," he muttered, sliding a finger inside of her. Her breath hitched and he smiled, "If you want to come along for the ride, you need to stop that and get going." He reached over to the bedside table with his other hand and dropped a condom on his stomach in front of her.

Alex could barely concentrate as he stroked her, but she somehow managed to rip the condom wrapper and slide it down his length. Fin watched, amused at how disoriented she was because of his attentions. Rock hard, Fin now guided Alex so she was directly over his errection. He stilled his movements and waited for her to make the move. When she shifted downward, he helped guide himself into her.

Fin leaned his head back against the pillows, breathing hard as he was enveloped by her warmth. Alex's breath hitched as he stretched her and she leaned forward, placing both palms flat on his abs. She let out a moan and slowly began to rotate her thighs. As she began to gyrate, Fin pressed up into her, watching her breasts move and her abs twitch as she tried to keep the movement steady. He soon felt her falter and begin to rock back and forth. He brought his hands to her hips, still letting her control the movement but synchronizing their motions and guiding her deeper. She looked down at him and met his gaze before closing her eyes and moaning, bringing one hand up to cup her breast. He sucked in some air and smiled at the performance.

She knows how fuckin' hot she is when she's like that, he realized.

But not allowing himself to be outdone, he grabbed her hips and lifted, allowing himself to thrust up and into her.

Her hands flew back to his abs to steady herself as they changed the movement again so she was sliding up and down his massive errection.

Almost unable to contain himself at the sight of Alex Cabot riding his dick, Fin shifted into a sitting position so they were face-to-face. Alex was unprepared for how this would change the angle and she cried out. Fin leaned forward and brought his face to her breasts, laving a nipple with his tongue and sucking the soft flesh. Tangling his fingers in her hair again, he pulled her head backwards exposing her throat so he could kiss his way up to her mouth.

He kissed her, hard, as she came. He followed seconds later, his movements becoming even more erratic. They both leaned back, him still inside of her, and grinned at each other. Fin took a moment to take her in; blue eyes bright, lips swollen, hair mussed, breathing hard with a thin sheen of sweat on her forehead. She grinned when she saw him watching and slowly went up onto her knees, letting him slide out of her and leaning forward to kiss him, snaking her tongue into his mouth.

She wrapped her arms around his shoulders and he squeezed her ass as they kissed slowly.

When they broke away, he smirked at the sight of her and ran his hands up her sides to cup her breasts. She was incredibly, incredibly sexy, but even Fin was surprised when he felt himself stirring again.

So Alex had a right to be shocked when he flipped them over so he was hovering above her and growled,

"Round three?"
