She pulled his spare key out of her bag and quietly unlocked the door. Inside she paused to listen, and to slip off her thong. She could hear the keyboard clicking in the room he used as his office and tiptoed down the hall to the door. He looked up in surprise as she entered, a look of surprise that quickly widened into a smile. "I decided to take a lunch break" she said, answering the questioning look on his face.
And then the phone rang. "Hang on a minute" he told her as he picked up the phone. "Sally" he mouthed at her and made a face indicating his frustration at being phoned by his least favourite colleague yet again. She laughed and moved behind his seat, kissing the top of his head and rubbing his shoulders. Then she slid her hands down over his chest and belly, nuzzling up against his ear and nibbling gently. His spare hand caressed her arm as he tried to explain something yet again to the woman at the other end of the phone line.
Hmmmm. He still seemed able to concentrate. She moved round to kneel beside his knees and ran her hands from his knees up the top of his thighs. He raised his eyebrows at her. He knew she was trying to distract him but at the moment the problems of work needed the greater part of his attention. His speech faltered slightly as her hands move up over the slight bulge in his trousers and she started groping him for real.
Slowly she ran her long fingers up the sides up his hardening cock, feeling him through his trousers. Tracing up and down that growing bulge, exerting just enough pressure to tease him, her other hand gently shifting his balls about. She could tell he was finding it harder to pay attention to Sally. Good.
She unfastened the button and unzipped him, then reached into his shorts to free his cock. She looked up at him and licked her lips. His eyes widened. She'd often talked about it but never gone done on him before. Her tongue reached out and flicked over the tip of his prick. A sudden intake of breath must have worried Sally because he reassured her he was fine.
The tongue continued its wet flicking, then swirled round the helmet, tasting his saltiness. Watching him all the time, she kissed her way down his length and then licked her way back up with firm strokes. Down and then up again before nibbling gently with her lips round the rim. She wasn't in a hurry, she was having fun tormenting him. He was long and hard as a rock now. He wriggled around a bit and managed to slide his trousers down free of his hips. Ah, that gave better access to his balls. She nuzzled her face against them and then nibbled and pulled at them.
And then she took pity on him and slowly pressed him into her warm, wet mouth, deeper and deeper. He sighed. Just as quickly, she removed him from her mouth and instead placed her hand round his now lubricated shaft. Up and down in long strokes, watching the foreskin sliding over his helmet. Oh how the sight turned her on. She'd dreamed of doing this for so long.
He was losing the plot with the phone call now, just giving the odd "uhu" to Sally. The hand without the phone had been stroking her, but now took hold of her head to try to guide her mouth back to his cock. She pulled back slightly and in a quick movement pulled her top over her head. He reached behind her with his free hand and managed to unfasten her bra, a move which took her by surprise. "How come men can undo a bra single handed?" she wondered. She let the straps fall from her arms, revealing her small but pert breasts, the nipples hardening as the fresh air touched them.
She moved herself between his legs and dropped her mouth to its target and began sucking in earnest. He took a deep breath and managed to excuse himself from Sally and finally put the phone down. He let out a long moan and reached for her breasts with both hands. She sucked harder, pulling as much of him into her mouth as she could before twirling her tongue round his length and then tightening her lips once more to squeeze him as she pulled back from him again. One hand moved back to his balls and started rolling them softly while her other slid up under his t-shirt, the fingers twining through the hair on his chest before finding his nipples and rubbing on the tip.
It didn't take long before he groaned that he was about to come. She sucked harder and was rewarded with a mouthful of hot salty spunk. She let him slide from her mouth and the next jet caught her on her shin, then her throat and down onto her breasts.
As he lay back in the seat, with a wide grin on her face, she set to work cleaning him up with her tongue.
And then the phone rang again.
