A/N: This story, frighteningly enough, was inspired by a lunch conversation at work.
This is for aussieforgood, as a thank you for all your help with my WIP. And, yes, dear, this is as smutty as I'm willing to get!
I don't own CSI. Scientific information is taken from .
Scientific Study in Four Parts
Part 1
"I've been reading."
"I'm shocked," Sara replied absently, without looking up from her email.
"I read a scientific study about prostate health."
Sara glanced up and raised an eyebrow. "Thinking of becoming an MD?"
"The study said that men should ejaculate twenty-one times per month to avoid prostate cancer."
Sara finally looked up from her email. "You're joking."
"Nope. You can read it yourself. I'll send you the link."
She smirked. "Is this like that magazine subscription you promised me?"
"No, dear." Grissom came around behind her, wrapping his arms around her and kissing her neck. "It's a real study."
Part 2
"Mm," Sara hummed, reaching back to hold Grissom's head in place. "So, you're telling me you need to ejaculate more?"
"It's all for the good of my prostate," he replied, continuing his assault on her neck. "You wouldn't want me to get cancer. You'd always feel guilty knowing you could have prevented it."
"So, I need to help you achieve good health?"
His fingers moved to the buttons on her shirt, undoing them one by one. "Pretty much."
Sara pulled away from him and turned her chair so she could look at him. "I could let you handle things yourself."
Part 3
"You could," Grissom agreed. "But, you wouldn't get to have any fun."
She gave him a sultry grin. "I'd have fun watching."
Grissom pulled her from her chair and into a heated kiss. "You don't want to be an active participant?"
"Well," she said, undoing his pants, "when you put it like that …"
Grissom kissed her again and pushed her shirt off her shoulders. "I knew you'd help me."
"I can say one good thing for this study." Sara stepped out of the pants Grissom pushed over her hips.
"Only one?" he asked. "I'm sure there's more than one."
Part 4
She giggled and fell to the floor, pulling him down on top of her. "At least it was published after we left the lab. If you'd read it two years ago, our jobs would have seriously interfered with your goal."
They both groaned as their bodies joined. Grissom kissed her as they found a rhythm.
"I knew that lab was bad for my health."
Sara moaned. "Yes," she sighed. "Rainforest – much – more – healing."
Grissom paused his movements to stare into her eyes. "In so many ways."
Sara reached up to caress his face. "I love you."
"I love you, too."
