Already turned on by the situation, by the power she held over him, the teasing she was used to was suddenly almost unbearable. He licked her through the fine material and she bucked beneath him; he slipped a finger inside her panties to run along her slit, and she swore aloud. He hooked his thumbs into the sides of the briefs and began to side them slowly down her legs, and she had to bite her tongue not to tell him to get a fucking move on and eat her out already.
With each inch of flesh exposed, he kissed her skin again, deliberately letting his lips trace a line somewhat tamely down her leg, knowing it would infuriate her. Then finally he let the garment drop down to her ankles. Gently, he spread her thighs, hooking her knees over his shoulders.
"You're delicious," he murmured, and the heartfelt words turned her on almost as much as his skilful and well practised foreplay. He leaned in close, and she heard him inhale; she imagined his face as he savoured the scent of her arousal. He leaned in a little further, and she felt his breath against her, hot against her skin; and then he gently licked into her.
The contact that she had been anticipating since before she had entered the room was electric, and her chilly facade dropped as she gasped his name, and grasped hold of his head, tangling her fingers in his hair.
Hungrily, he lapped at her, sucking and licking like a man dying of thirst whose only source of moisture was her wet pussy. She had been used to getting good head, but today it seemed like he was inspired. His tongue danced over her slick folds, and when he took her clit into his mouth she almost cried out. Biting on her lip, she managed to stifle her moans of pleasure. She felt him slip a couple of fingers inside her; she moved against his touch, and then gasped as he found her g-spot. The orgasm she had been trying to hold back burst over her, and she bucked under him. Still he licked her, and as the spasms of ecstasy began to fade he sucked hard and despite her best efforts she couldn't help crying out as she began to come again.
Intent on her own pleasure, she clasped his head to her crotch, and he continued to lap at her, circling her now swollen and sensitised clit, riding the very edge of what she could bear.
Finally, she could take no more, and pulled him away. His face was soaked with her juices, and he looked dazed -- a little how she felt, she realised.
"Need you... inside me... now," she gasped out, pulling herself up so that she could reach for him, fumbling to get to his fly and free the hard on that was making a tent in his trousers. For a moment he was still not caught up with events, but then he was aiding her, and his cock was free in seconds, his hands parting her thighs again, entering her even before she was ready, afraid she would change her mind.
He was hard and thick inside her, and she relished the feel of him, how he filled her, how he parted her lush wetness again and again. Her body and senses already flying, it seemed only moments till she was gasping again, so close, her arms around his neck but her head thrown back, and then she shuddered as another intense orgasm rolled over her.
He did not lose his rhythm for a second, and as she resurfaced she could hear in his voice that her body contracting around his hard-on had brought him close to the edge. For a moment, she considered having mercy, and then she pushed him away and scooted herself further onto the desk; missing the feel of him inside her, but reminding herself that this was, after all, his punishment.
He stood, gaping, his cock shiny wet from her pussy, and looked at her, dumbfounded. She gently shoved him away from the desk to give her room to hop down, and began to gather her clothing.
"But... but I... you..."
Slipping her skirt up over her thighs, she glanced up at him.
"You don't get to come just yet, my sweet," she told him, her voice saccharin. She quickly donned her bra and then retrieved the crumpled blouse from the floor. As she buttoned it, she commented, "Damn, I am going to have to iron this again..."
He simply stared at her, his face a picture as he realised that yes, she really did mean it.
She picked up the black briefs and shoved them into his unresisting hand.
"You can keep these for the moment." She grinned wickedly. "There's a matching bra... I was wearing them last night, too." She cocked her head to one side and looked at him speculatively. "If you're very, very good, I might show you."
She tucked a stray strand of hair behind her ear, and he realised, with a jolt that made his cock ache, that besides the extra flush to her cheeks, no one would know she had just come her brains out, or that her delicious, naked pussy was only inches out of sight under her staid looking skirt. Suddenly she reminded him of the eighteen year old he'd met at college, and he remembered how they had fucked like rabbits every chance they had got...
"Happy Valentine's Day," she said, and the strolled away from him, as casual as if she had just stopped by to drop off a card. "You should let me down more often." She turned back to look at him with her hand on the door and looked him up and down, nodding in satisfaction as she noted the raging hard-on that still refused to fade. Later... later they would both get what they wanted. And this would fuel their fantasies for weeks, she was sure. "See you at home."
She winked and sidled out, closing the door behind her. He stared at it for a second, then down at his erection, wondering which was the worst risk; being caught jerking off, or attempting to work through complex cases with her scent hanging in the room like nasal Viagra and most of the blood in his body concentrated in his crotch.
He shook his head as he crossed the room and locked the door, then turned to lean on it, so in need of immediate release that he didn't even move to sit back down. She knew how to make her point, he thought, as he began to pump his hand up and down his cock; and he wondered if he'd have to wait till next year before he got the chance to stand her up again...
