"Xylophone?"

Catherine nodded.

"Why xylophone?"

"No idea. A bit weird isn't it?"

Grissom shrugged.

"I can't judge 'weird'. I race cockroaches, remember?"

Catherine chuckled.

"How come she decided to play that?"

"Oh no, not only wants to play xylophone, she wants to become world's number one concert xylophonist"

Grissom's eyes widened.

"Cath, I don't think that even exists"

"That's what I told her but she said she'll become the first concert xylophonist ever"

"Then I'll bow to her determination. Wonder who she got that from?"

Catherine smiled to Grissom's compliment and he knew he said just the right thing.

"I know where she got her determination from, but I sure don't know where she got her likeness for percussion instruments. Clarinet was my favourite ever."

"Clarinet?"

Catherine got under the covers.

"I've always enjoyed blowing on hard long objects..."

"Oh God! Catherine!"

She crawled upwards to kiss his mouth, then his nose and chin to finally rest her head on his chest.

"If Lindsay ever gets as good with xylophone as her mother is with wind instruments, I'm sure she'll make a great xylophonist"

Catherine wrinkled her nose at him.

"You shouldn't compare my sexual abilities with my daughter, Gil, that puts not so nice thoughts into my head"

"I'm sorry. But you can't ask much from a man whose brains have just been blown...away"

Catherine giggled and bit playfully on his shoulder enjoying his salty taste.

"Xylophone... How come that word sounds so sexy on your lips?"

Catherine gave him a quick kiss.

"I guess I just happen to like 'X' words. There aren't many you know?"

Catherine kissed him again, more deeply. When they parted, a devilish smile spread across her face.

"I like 'X' rating actions more..."

Grissom spanked her.

"Cath! You're incorrigible!"

"I know... and I'm also insatiable, and though I really enjoyed my little performance, I'd love to hear you play"

Grissom flipped her onto her back.

"Have I ever told you I'm an expert at piano?"

Catherine arched an eyebrow in disbelief.

"I've been told I have the most gifted hands..."

"Oh Gil... Oh my... Oh God!"

Catherine's breathing normalized as her mind slowly stopped buzzing with pleasure.

"I told you I had great hands"

"And I should've remembered you never lie"

He showered her face with kisses before moving to her breasts.

"I know another instrument we could practice..."

Grissom stopped nipping her nipple.

"Clavicordium comes to my mind but I've no idea why"

Catherine laughed at his comment and he watched her breasts move unashamedly and licked his lips.

"I was thinking about zambomba"

Grissom got off of her and laid by her side.

"Zombomba?"

"Zambomba. It's Spanish. Lindsay showed me. They have the most amazing inter-cultural classes in school nowadays"

"How is it played?"

Catherine grabbed his hand.

"Let me show you"

She carefully made him close his hand, finger by finger, and when only his index was left, she took it to her mouth and suck on it. Grissom groaned.

Catherine chuckled.

"They taught her that in school?"

"No silly. That was my own pedagogical attempt to show you."

"I was planning to go back to school if they taught that..."

Catherine pinched his butt.

"Pay attention you bad boy"

"Yes ma'am"

"The zambomba is a clay vase..."

And she kissed his finger,

"... that's covered with calf ..."

then she licked it,

"... and has a cane stuck in it. You get the stick wet, and when you slide your hand over it, friction makes it sound"

Grissom smirked at her idea.

"That sounds nice, but I think we can better that"

"You do?"

Grissom moved to get between her legs.

"I'll be the stick, you'll create the friction"

"You got it"

And with that he slid into her with ease.

"No sound... I'll try again"

And he slipped out of her only to go back inside. This time Catherine moaned.

"I'm good at this. I made it sound at my second attempt..."

Catherine grabbed his ass.

"Shut up and keep the music playing!"
