"Kiss me..." Sara whispered.

Grissom froze as he lay across Sara's body, in the midst of reaching to latch the seatbelt down securely across her lap. He turned his head slowly and looked into her eyes, her face just millimeters from his own.

"Now?"

"Now is good…" she grinned, her eyes twinkling as she leaned forward and kissed him softly, lightly brushing her tongue along his lips seductively as she slowly pulled back and continued speaking, "but I meant when the ride gets going."

Grissom's own tongue darted out in response to her tease and he licked his lips, savoring the taste of her on them. Ever since he had taken Sara home from the station those few months ago and he had finally realized that his need for her was worth all the risks in the world, he couldn't get enough of her kisses, her lips, or any other part of her body for that matter. His mouth turned up into a curious grin.

"Why when the ride gets going?"

"I'm conducting an experiment."

"Really. What experiment could that be?" he asked as he finished buckling her into the Jaws of Life - the newest roller coaster on the strip. Grissom's friend, Woody, was the head mechanic and had loaned him the key so he could have full access to the ride anytime he wanted; a gift from one roller coaster enthusiast to another.

"Remember when we were investigating the accident on Pharaoh's Fever at the Sphinx Amusement Park? You said the release of epinephrine and adrenaline while riding a roller coaster can produce a stimulatory effect." Sara paused, "I believe your exact words were, 'It enhances ejaculation.'"

"Yeesss…" Grissom cautiously replied, feeling his face flush.

"You never did cite your source you know, and, well… as a scientist… I want proof."

Grissom sat back in the seat, incredulous. He knew Sara was adventurous, but he could never have imagined… He tried to hide his smirk.

"Sara, I'm shocked at your behavior."

"Oh, stop it… I see that smile!" Sara swatted his arm, and then whispered in his ear in a low and sultry tone, "You know you want to…"

He had to admit, she was right about that. Combining three of his favorite diversions – Sara, roller coasters, and sex – how could he say no? With his left hand he reached for the ride lever and pushed it down hard to engage. The cars moaned and creaked as they slowly began to creep forward. Grissom then placed his other hand on Sara's thigh and turned to her, his arousal evident and his voice husky and full of lust.

"You know I'm always up for an experiment."

Sara gave Grissom a wide, gap-toothed smile and then laughed as the coaster gained momentum and swooped down the track into the wooden façade shaped like the ride's namesake, the piston-rod hydraulic tool used to pry open vehicles involved in accidents when a victim is trapped inside. Grissom gazed at Sara, so happy and full of life. It wasn't so long ago that she didn't even smile, and neither did he. Now – he couldn't stop smiling and she's laughing in the Jaws of Life.
