"What? Too much?" Gil glanced at Catherine.

"Not enough," came her reply, her head shaking as she smirked.

Gil's eyes watched her carefully for a moment. Then with a casual flick of his hand, he locked the door to the room. Catherine's eyes darted to his, a wary look on her face.

"What are you up to?"

"Locking the door."

"My eyes are not that bad, Gil."

"Then why did you ask?"

"Because I'm wondering why you locked the door."

"You said I wasn't tough enough for you."

"You wouldn't."

"Are you daring me?" Gil advanced towards her.

"Gil.Brass is in there! With a suspect and a uniformed cop!"

"Well I'd rather them in there than in here with us. Could be a bit crowded, and I don't share you with anyone."

"SHARE me? I am NOT a possession Gil Grissom! I."

Before she could continue to rant, Gil had pushed her up against the wall, lifting her upwards. On instinct, her legs wrapped tightly around his waist, and she looked at him indignantly.

"You're incredibly sexy when you're angry," he murmured.

"Gil, I swear to god, if you."

His lips crashed down on hers and Catherine whimpered, the kiss deepening instantly when she opened her mouth. His hands delved beneath her shirt, smiling as he ran them over her breasts. She gasped into his mouth as he began to knead and massage the tender flesh.

"Gil." She moaned. "I'm not wearing a skirt."

He lifted an eyebrow. "You think that's going to stop me?"

Catherine narrowed her eyes at him. "No, you big caveman. I was just reminding you that there's no easy access and could you hurry the hell up and take my pants off!"

Gil gently let her down, his fingers going to work on her pants. "Weren't you the one earlier who was not going to have sex in here with me?"

"What can I say?" she whispered, looking down at him. "You turn me on just by the way you look at me."

He smiled at her and then ran his fingers up the insides of her thighs with a feather light touch. Her thighs trembled and she leant against the wall.

"Gil.we don't have time for that."

"If I want to touch you, then I'm going to touch you," he said roughly. "And don't interrupt."

Her eyes widened as she watched him, his fingers probing her wetness. He rubbed a finger against her clit and she pushed herself against his hand.

"Oh.Gil."

He finally stood up and pressed his lips to hers again. In one swift move, she was up against the wall once more, and she wound her legs round his waist. To her delight, he had unbuckled and unzipped his pants before he had pushed her against the wall again. She reached between them, licking her lips as her fingers brushed against his straining erection.

"No touching," Gil growled, grabbing her wrists and pinning them together over her head.

Catherine pursed her lips, glaring at him. "You know."

"Want me to get tougher?"

"I'd be happier if you'd just take me, you smug."

"Catherine Willows! Do you kiss your daughter with that mouth?"

"Gil Grissom, do you want me to kick you in the balls?"

He said nothing, giving his answer by thrusting deep inside her instead. His mouth closed over hers just as she let out a cry of pleasure at the intrusion.

"Don't be too loud, sweetheart. You wouldn't want Brass and the others to come in here, would you?"

She whimpered as she shook her head, the pressure building up inside her almost unbearable.

"We have to be quick, baby," he murmured, kissing her softly. Gil started to thrust deeply inside her. "God.Cath.you feel so good."

"Don't stop," she whispered, clinging tightly to his body. "Please.don't stop."

"I'm not going to stop," he promised, kissing her once again. Gil pushed deeper inside her, his hands gripping her hips and pulling her back on his erection. He could feel her tightening around him, and he took one of his hands away from her hips and cupped her right breast.

Catherine moaned at the added pressure, her body squirming against him as she tried to get him to touch the right places. He was driving her insane with need and she could feel her orgasm lingering just out of her reach.

Gil's thrusts quickened and he thrust harder. He could see from the look in her eyes that she was close, and nothing made him happier, or more proud, to watch her as he pushed her over that edge.

When he saw her eyes begin to blur, his lips descended onto hers for a long kiss. He felt her body tighten around him, and he groaned into the kiss, able to feel every tremble of her body.

Catherine whimpered into the kiss as she felt him spill inside her, his body stiffening. His warmth intensified the pleasure of her orgasm, and she gripped him tightly, needing something to anchor her against the heat.

They sank to the floor of the room, chests heaving as the fought to catch their breaths.

"I think.I think I may need some recovery time," Catherine murmured, resting her head on his shoulder.

"Shall we adjourn to my office, darling?"

She nodded, then tugged his hand. "Hey Gil?"

"Yeah?"

"Don't be using this brand of tough guy act on Sara, okay?"

Gil grinned. "Cath, this tough guy act is just for you."

"It better be." She winked at him. "Otherwise I might have to bring out MY tough act."
