in my current role (a large office) myself and a girl who i worked with closely were emailing each other throughout the day, we flirted, joked and that kind of thing. But the flirting got a little steamy when we started talking about sex and that type of thing, i put forward to her that we should meet downstairs, i walked down and waited patiently, anxious if she was going to turn up, she did and i took her by the hand and pulled her into the female toilets, we went into a cubilce block, i sat down, we kissed and fondled each other, i lifted her little blue skirt and slid her soacked knickers aside, her pussy was aching for it (she is 27, recently married and her husband doesnt give it to her) so i slid her over me, she stradled my hard cock, and it slid deep into her with ease, i lifed her top pulling out her big round doubdle Ds, she had huge hard nipples i sucked and pulled at, she rode me hard and fast and i blew hot loads of cum into her deep wet warm pussy, she slumped over, kissed me, then got up, pulled her skirt down, adjusted herself and left for the day...
the following morning, she emails me saying thanks, and to tell me that she nearly got busted as when she was walking out of the office down the stairs, my cum was running down the inside of her leg.
