I'd worked with Abbie for a year or a year and a half, sitting next to each other. We'd car shared a lot, both living an hour or so away, and had a solid friendly working relationship. She was quiet and shy, but open and intelligent too, and we'd got to know each other well. We'd have a laugh and felt comfortable with each other. She was 28, I was about 20 years older, but although it felt like we were peers there was never any sexual frisson, we were both reasonably good looking though. She was about 5 foot 7, with a sturdy athletic build - a good mile runner with glasses, straight medium length light brown hair. Suddenly on a work night out (someone's leaving do) we had, drunk, had a quick secret snog, much to both our surprise. She'd initiated it. We hadn't mentioned it since, but it felt exciting and with a delicious tension rather than awkward.
We were by habit both in early, at just before 8 we usually had the place to ourselves until the others started dripping in after 9. If there was going to be anyone in joining us for the first hour we'd know. So one evening, when Abbie texted me to ask me if I felt like coming with her a bit earlier than usual the next morning, I knew she either wanted to talk to me or (less likely) have a repeat clinch, as that gave us a good hour and a half alone.
We met fat our usual spot for car sharing, she drove (her turn) and on the way, whilst there was a little bit more exciting tension than normal, we just chatted as usual. We climbed the stairs to our firm's office, went to our desks, did the usual of unpacking our bags and hanging our coats, and then immediately afterwards she turned to me, grabbed me, and kissed me softly and passionately. I was astonished and delighted, doing this early and sober made it even better than our drunken snog. We pushed against each other and kissed for the longest time.
When we released, I turned her round and bent her over her desk, she did so willingly. I got on my knees behind her and started to lift her tight black skirt. As I eased it up I enjoyed her strong pale thighs coming into view - I adore athletic women - and one thing I had always admired about Abbie was her firm shapely looking bottom. I pushed her skirt right up to her waist, and admired not just her amazing bottom, but her delightfully pretty panties. They were expensive looking - full cut, white lace, with mint green and raspberry pink ribboning detail around the edges. I caressed her bottom through the material. You'll find out if you carry on reading that I'm a committed panty fetishist, and I was in heaven. Not just a man who enjoys sexy sensual underwear, but unspeakably dirty and imaginative. I was of an age where I was sexually experienced and also confident enough that I decided at that point to push my luck a bit and see if Abbie would join in with some really filthy foreplay and sex.
I stood up, whispered in her ear from behind - "Abbie, I'm going to sniff your bum." She made a noise that expressed embarrassment and arousal in equal measure. She's soon stop me if she didn't like it. I got back to my knees, and gently and slowly pulled her panties down to the top of her thighs. They looked even prettier like that, and her bottom was looking better and better. I slowly pushed my nose up against the crack of her cheeks and inhaled. As I'd hoped, her bottom smelt not at all dirty, but of a slightly sweaty, truffle-oil like, musky feminine beauty (a smell I'd adored since my first 69 as a teenager, when a beautiful Chrissie Hinde lookalike, with a shapely big bum, pressed herself against my face as I got sucked off for the first time). My nose was in Abbie's bum crack, my mouth and lips by her pussy.
