It's late and her mouth is hot on his. There is a prominent taste of whiskey and wine on the tongues battling for dominance.
And it feels good, better than either of them thought it would be to give into sensations rather than thought. They both know she will not be staying here in the long run, and it feels only right to make the most of these empty hours.
At this exact moment the only thing that matters to her is his hand traveling up the inside of her thigh, her legs colliding with hard wood as she stumbles back on to his desk, knocking files to the floor.

His fingers slipping past her skimpy knickers. A whimpering sound leaves her throat in a feminine gesture, so unlike the Detective Inspector he is used to seeing. And right now he is seeing a hell of a lot more of her than she would usually allow.
Her curls are tangled, the shimmering red of her bra is peeking through her unbuttoned shirt, her dark grey pencil skirt is bunched tightly around her waist, her damp satin knickers are pushed to one side and her stocking clad legs are wrapped around him.
Her cheeks are rosy with arousal, and the only thing she can concentrate on in this drunken hazy of sexual desire, is the need to unbuckle his belt. Once released from the denim en-caging him, he pulls his superior closer spreading her legs as far as possible. Hips greeting each other as he hastily enters her. With his body he presses her farther back against the cool surface of his desk, with both hands he grips her supple bottom and raises her to meet his every thrust.
A groan of pleasure passes between their joined lips as skin crashes against skin in the darkness of CID. He reaches a hand between their bodies to tease at her swollen bud, pulling and pinching, becoming gradually rougher as she arches her back away from the table she tensed and fluttered around him. Biting down on her lower lip to stifle her moans, Alex shudders against him again, when he continued to push gently inside of her working her through the last remnants of orgasm.

In a series of coordinated moves Alex pushed a stunned Ray away from her and into the hard chair at his desk. Panting heavily she lowers herself into his lap and kisses him lazily as she slowly lifts herself and sharply fall back onto him, causing him to buck upwards into her with a surprised grunt. The chair squeaked against the tiled floor every time she grinds her body into his. Grabbing a firm hold onto the lapels of his leather jacket she pulls him flush against her, and coaxes him closer to his down fall.
As the friction among them rises to its crescendo, their coupling becomes frenzied in it's release. Alex let free a sigh of contentment, as Ray placed clumsy kisses against the soft skin of her neck.
