They'd been out straight from work, Paul meeting Lucy at her office. Their dinner had been light, and afterwards they'd left the restaurant and discussed options for what next.
She hadn't told him how horny she was feeling at dinner. Nor had she told him why. The plan had been formulating all day, ever since her boss had told her that she'd need to lock up that night, leaving her the keys.
Lucy had thought about being fucked over her desk a few times when playing with herself. The vague thought had developed into a full blown fantasy, one that delivered very satisfying orgasms. Tonight she was going to fulfil it she'd decided. Little did she know that living the fantasy of being fucked over her desk was only the start.
As they walked arm in arm down the road, him suggesting pubs to go to next, she interrupted and asked if they could back to her office.
'Why?' He'd asked 'Forgotten something?'
'No, I want to do something. Don't ask me anything else' was all that Lucy said in reply. For him this was enough, he knew her well enough to know what was going to happen.
'Let's go' he said.
The moment they closed the door to the office they started kissing; long passionate kisses with their tongues touching frequently. His hand travelled to her crotch and rubbed through her jeans but she stopped him.
'My desk' was all that she said.
Lucy told him to perch on her desk while she sat in her chair, and she started to undo his trousers and pulled out his cock, already hard. He moaned as she released it then immediately took it into her mouth, her tongue working its way all around his thick end. She started to take more of it into her mouth, sucking hard, and he held her head to encourage her. She pulled off momentarily, taking deep breaths and looking at his cock, which was liberally coated with saliva, before plunging her mouth on it again. He lay back enjoying the pleasure, turning his head absently as the sensations grew, and that's when he saw the woman.
The office they were in overlooked a narrow alley, with another office building on the other side. It had been unlit when they arrived, no sign of life, but they'd hardly given it any consideration anyway, such was their lust, but now there was a woman, about 40, stood in the window staring at them, clearly watching them.
'We're being watched' he said.
'What!' She said, pulling his cock from her mouth. 'Where?'
He pointed to the woman, still staring at them. Still holding his cock, she stood and stared, then let go of him and walked to the window, reaching for the blind. Before she could close it though, the woman shook her head, wanting her not to close it.
