Cal opened the door and Gillian darted in and punched in their code into the alarm pad on the wall. When the door closed she put in a different combination to set the perimeter alarm, just in case anyone else decided to show up at the Lightman Group on a Sunday evening... They'd get a warning this way. Cal was already at her back, warm, his hands possessive as they slid around her body, to tuck into the top of her jeans. "Sure you wanna do this?" He murmured against her skin as he leaned down to kiss her neck.

"Yes," Gillian whispered back. She pushed against him and he gave a little growl which sent a shiver through her and honestly, the idea of having sex on her desk right now was actually really appealing; the anticipation was already low in her belly. She turned and took his hand and led him down the hallway quickly and around the corner. Of course, they should also really get this over with before she lost her nerve and got paranoid that someone was watching.

They reached her office and she turned her back against the door to push it open. Cal was watching her with slight curiosity, but mostly arousal and Gillian felt the tension in her stomach spike. She pulled him closer and reached up her free hand to hook around his neck, bringing her mouth up to meet his. He kissed her hotly, like he had just been waiting for the connection, like he had been dying without her and could now breathe again. He pushed into her body, nudging her back and she lost track of where they were in the room; caught up in him. He said her desk and eventually she felt something solid bump against her back. She pulled away to catch her breath and looked behind her and yes, there they were, at her desk, her chair haphazardly off to the side.

"You can say stop if you want to," Cal told her gently, his blue eyes earnest.

Gillian shook her head. "No," her voice was shaky and she was already so turned on she could feel her body drawing towards him. She probably couldn't stop at this point if she wanted to. She hooked both arms around his neck to press her chest against his. His eyes were dark and the sun was setting and no one would see... no one would even know but them. She shivered at the thought, her mind already racing ahead.

Cal gave her a slight grin and dropped his arms around the small of her back. He rocked them side to side, as he shifted his weight from foot to foot. "You're brilliant you know?"

Gillian gave him a smile. "Just get on with it before I change my mind."

"Ok," Cal murmured and went back to kissing her. He let her go and she missed the warmth of his arms around her until she felt his fingers at her jeans. The touch sent a shock straight up her but she also felt a pang of a disappointment he really was just going to go straight for the jugular. If it was a quickie he wanted, or intended, she wasn't prepared for that. But once her jeans were undone his hands moved again. He smoothed them up her ribs, pushing the material of her jersey and her tank top underneath with them. He squeezed her breasts, his tongue soft against hers. She was aware of her heart now, could feel it starting to pound and he tasted like chilli. It made her burn for him.

Cal pushed her jeans down and lifted her to sit on the desk. He stepped back to pull her trousers off and tossed them to her chair. He gave her a grin and she could see he was thoroughly enjoying this. "Don't get too smug Doctor Lightman," she warned, still not sure how he was going to pace this.

Cal grinned as he started kissing her neck again. "Well Ms Lightman, I was incredibly displeased with your dictation today. I'm gonna have to pound your incompetence out of you."

Gillian gasped and giggled and pulled him in against her with her thighs. "I'm so sorry Mr Lightman," she went on, picking up his game. "How can I make it up to you?"

Cal laughed lightly and pulled back to see her face. She pouted, eyes wide, looking up at him contritely. "Well," he leaned down to give her a brief kiss. "I can think of at least one way," he told her gently, his voice high and light.

Gillian laughed again and Cal chuckled. He pulled her jersey off carefully, so he didn't catch her earrings up in the material and threw that with her trousers. "Can I keep my job then Mr Lightman?"

"That's Docta Lightman to you, young lady."

Gillian threw her arms around his neck. "Ooooh yeah I like that. Keep talking like that."

Cal growled and leaned in to kiss her neck again, teasing her slowly, letting his hands trail over her skin softly so she shivered. "Cold?" He asked innocently.

"You're over dressed," Gillian reprimanded. She pushed against his shoulders and then leaned back on her hands, her fingers knocking into the cup holding pens and the edge of a photo frame. "Take it off," she gave a jerk of her chin.

Cal tried to step back but her legs tightened and she wouldn't let him go. He grinned again as he pulled off his jersey, then the t-shirt underneath. "And those," Gillian indicated with her head, watching, waiting, enjoying it. Cal reached down to the catch of his jeans and popped the top button open. She could see he was already straining through the denim. He watched her watch him undo all the buttons slowly, revealing himself through his boxer-briefs.

"Gillian," he grumbled.

"Keep going," Gillian directed having to shift slightly to let the feeling back in her hands.

Cal pushed his jeans down at the hips and the material caught where her thighs were pressed tightly around him. He finally looked down and gave a little indication with his hand, "Kinda caught up here."

Gillian let him go and he shimmied his jeans down to the floor, then took her legs and brought them up higher to his waist, tipping her back. She leaned on her elbows and Cal moved in closer so she could feel the hardness of him against her. She gave a little groan and he pushed harder, moving his hips up and down and she clutched at him, "Cal!"

His hand moved between them. "You're so naughty Gillian," he murmured against her throat. "You're gonna make a mess on your desk."

"Me?" Gillian gasped. "Who's idea was this?"

"Yours," Cal growled, slipping beneath her underwear to stroke.

Gillian's hips pushed up against him. "Oh god," she moaned again, involuntary this time. "Yours," she countered. "This is your fantasy."

"God yes!" Cal agreed pushing a finger inside her.

"Oh!" Gillian cried and clawed at his shoulder again. She still needed one arm to hold herself up. She found purchase against him and wrapped her right arm around the back of his shoulders, bringing him closer to her, so she could draw her tongue around his ear and make him grunt with the pleasure of it. She teased her teeth against his lobe and the edge of his jaw while he wound her up. Finally she was gasping for air and twitching, her body begging for the release. She could feel him rock hard against her legs as she squirmed out of control. She let go of his shoulder and pushed herself up from the desk. She pulled him free from the restraints of his underwear.

His face dropped to her chest and he groaned as she stroked him gently. "You're killin' me," he groaned.

"Shh," Gillian told him. "Let me do this for you Mr Lightman."

"Don't tell my wife."

Gillian smiled slightly, her back ached from holding herself up and his hand was still between her thighs, alternately squeezing and fluttering but there was barely any room for him or her and finally he broke away. "Enough," he ground out and pushed her hands aside. Gillian lowered herself back against the desktop; there was just enough room for her to fit but she heard the cup drop to the floor and bounce, the pens scattering. Cal leaned over her body, pulling her closer to him by hands in the back of her knees. She looked up at him, waiting, rising her arms to meet him, to hold him while he screwed her, the anticipation making her want to hurt him if he did not hurry the fuck up.

"Hang on," he grunted and leaned over to the left. Gillian turned her head to see as he flattened the photograph of him and the boys next to her computer screen so it was face down against the desk. She laughed again and he grinned and she lifted her hips up to him. "All right, all right, don't rush me."

"Oh fuck you," Gillian murmured with a huff.

"Fuck me?" Cal questioned innocently. "Fuck me?" He leaned over her again, over the desk, gripping the back edge of it, the coarse hair of his navel brushing roughly against hers. She could feel him pressing against her. Gillian reached up her arm, pulling his neck down closer so his chest was against hers and she arched her back so her breasts and bra scratched over his nipples and he growled again.

"Fuck me," Gillian whispered in his ear, shifting her feet behind his calves so he had plenty of space and encouragement. She pushed her hips up to meet his, taking the tip of him in. Cal gasped and Gillian murmured against his temple again, her breath feathery as her stomach tightened with wanting him. "Fuck me. Fuck me Mr Lightman."

Cal gave a grunt and pushed against her and she groaned in desperate pleasure again, tucking her legs up against his waist. After that he didn't need encouragement and their gasps and moans echoed against the walls, building with excitement until they cut off sharply. Gillian felt the slow burn wash over her like a caressing wave of familiarity; the slow dirty kind that rippled on forever and made her forget where she was. But still, Gillian was pretty sure she recovered before Cal did, or at least came back to her senses first. His face was buried against her shoulder and even though she coaxed he remained tense for a long time. He turned his head to press his mouth against her neck. "Cancel my gym appointment Ms Lightman. I've done my work out for today."

Gillian laughed and he pulled back to grin at her. The sun had set and the room was getting dark quickly. They panted at each other for a moment. "That was fantastic," Cal told her sincerely.

"Yeah?"

"Oh yeah. God yeah. Wait, yeah?"

"Yeah," Gillian nodded, and yeah, she did have to admit, there was something deliciously sordid about having a shag on her desk. There was no way she was going to look at it the same now. Cal probably wasn't going to either. Probably? Definitely not. And there was no doubt he was going to tease her or give her a lewd grin the next time he saw her sitting behind it.

Oh god she hadn't thought that through. It could be a very bad thing.

Cal withdrew but kept his mouth close against her. "Tell me about yours."

"My what?" Gillian asked surprised.

"Your fantasies."

She could feel him shifting, his hands brushing against her as he used tissues from her desk to clean himself and fix his underwear back in place. "I don't," she started.

"You have to," Cal countered. He straightened up and bent down to pull up his jeans. Gillian propped herself up on her elbows again, letting her legs swing. "You have to have somethin'."

Gillian gave a slight shrug. Cal shook his head, finishing with his jeans. He pressed his hands down on the desk, either side of her and leaned in close. "I don't accept that. Tell me," he murmured softly. "I won't laugh."

"I," Gillian started but found, maybe on some level, she was embarrassed. She pushed him away.

"Gill?" Cal stepped away from her, finding her shirt and jersey so she could re-dress. "Is there somethin' I should know?"
