Back in the late eighties early nineties my wife was friendly with a bus driver who was always asking her out,she found this flattering,one Tuesday her and female friend decided to go into town by bus.well my wife always liked to dress up very sexy and daringly short skirts, low cut top,s and we went out together she would always wear see through plastic panties this was our secret which as i thought,but on this day she dressed in a very short PVC mini skirt fishnet tights and plastic panties,when the bus arrived the driver was her friend he let them off the fare as his shift had finished and bus was empty,so wife and her mate sat at the back of the bus with my wife sitting in the middle of the bench seating the aisle she could see the driver looking at her so she kept opening and closing her legs and teasing him ,the driver pulled into a secluded bus lay by,switched off the engine and went up to my wife and said to her if you keep teasing I will have to sort you out she said to him be a good boy and drive the bus,with that she flashed her crotch at him, and was secretly wanting him to have her,her friend got up and moved seats leaving my wife and driver at the back of the bus she giggled like a little schoolgirl this turned him on even more to the extent that he pinned her down on the seat and pulled her tights and plastic panties down and fucked her on the back seat which she was wanting him to do for,a while ,later that day I came home and was in the back room when my wife who didn't realize I was home was telling her friend that she enjoyed being fucked by the bus driver and that she was going to tease him next time on the bus and she would wear her lucky knickers (plastic ones),after hearing this I couldn't resist wanking off at the thought of not only the driver knowing her kinky plastic knickers fetish,but fucking her as well,when I confronted her we agreed that we would go to dogging areas so that other men could pull her plastic panties down and fuck her this we would do regularly weekly and every time I fuck her I imagine the driver on top of her and fuck her hard.
