I guess we were both planning it, the way it happened. There was no good excuse for us to both be there on the weekend. But I'd made a point of mentioning to her on Friday as we left that I'd be in, and she told me later she didn't decide for sure until she saw my car alone in the lot.
Like an idiot, I was actually crawling under the conference table when she walked in - I'd dropped a pen. So the first I knew she was there was from her laugh, as she stepped in the door and walked to the far end of the long table. She was saying something funny about my undignified posture, but from beneath the table I was too busy watching her bare short-skirted legs walk by to listen. I was particularly distracted to see her step out of her shoes along the way. Mumbling some excuse, I "innocently" started to wriggle out from underneath at her end of the table, nudging myself out on my back. I'd expected her to step aside - we didn't know each other well at all - so I was stunned when instead she stepped her left foot across me and onto a chair. Suddenly I was staring up her breezy little skirt, with nothing between my face and her tight little ass but the sound of her giggle in the empty building.
It knocked the breath right out of me - here? her? my God! - and I saw her legs tense as I paused for a moment, as she wondered what kind of mistake she'd just made. When my hand traced softly the skin behind her raised knee, she sighed just a bit - relieved that I wanted her too, that I'd take what she gave. Hearing that sigh, I decided this was going to be the best mistake she'd made all day long.
I settled my shoulders in underneath her with a little chuckle of my own - no need to hurry now, I had her pinned with my eyes. My left hand traced up and then down the back of her thigh, relaxing her tension a little. I licked the fingertips of my right hand before lightly drawing them across the back of her right ankle, then circling my fingertips up her calf to the back of the right knee. She shifted her weight slightly to spread her legs that much more, and to either side of her irrelevant skirt I saw her hands grip the edge of the heavy wood tabletop. When my hands slid up to palm the beautiful cheeks of her ass, she had enough leverage to push back against them a little bit, making it easy for me to draw them apart and look at her, to force her dampening lips open without yet touching her cunt at all.
