Work is.....intersting

i was at work today and a pretty middle aged women came in. she was around 30 or so and was wearing a fairly short flowing skirt, which revealed her sexy curvy creamy thighs. i had a quick glance over and she gave me a smile. i carried on working, thinking nothing of it.when i next looked up...well i wasn't expecting what i saw!The lady was bending over, her skirt way up over her big curvy arse. revealing her lacey, black french knickers. i couldn't beleive it!! i just stood there, staring at this perfect arse. it almost gave me a hard on right there. when she finally stood up(after what seemed an eternity), she turned and looked at me. once again with a big smile on her face. this time with a sexy glint in her eyes. she knew what had happened and that i saw it all! it turned me on so much, it was all i could think of all afternoon. as soon as i got home, i had the best wank i've had for a long time, thinking of that filthy MILF that flashed me her amazing fat arse....
