It was over 45 years ago, but I still remember her I was a young Squaddie, a Sapper serving in the Royal Engineers and, unfortunately, I was married and not very happily. Because of a shortage of married quarters in the garrison, we'd been allocated a "hiring", a civilian hound away from the garrison area, rented by the Army in place of the official quarter. Next door but one were a couple about 10 years older than us with two children who my wife would babysit for occasionally. This particular evening my wife was unable to babysit because she had a part time job so I stepped in instead. A fairly uneventful night, the two children got themselves ready for bed and soon settled down leaving me to watch a bit of TV. At about midnight the wife, Mary, returned from what had been a works reception and told me that her husband was taking a female colleague back home and, as we chatted, said he would probably be some time as she suspected he was having an affair with her. I commiserated with her and then, on impulse, out of my seat and gave her a light peck on the cheek and sat back down again. She asked why I'd done that and I said it was to let her know she was still attractive. She gave a wry smile and said "Oh yes?" So I got out of my seat again and kissed her again, this time on the lips. I drew back, we looked into each others eyes and kissed again, this time open mouthed and my tongue gently feeling for hers. Drawing back again, I slid my hand up the inside of her thigh and, as I realised she was wearing stockings with suspenders, she opened her legs wider. I slid my hand up further and kissed her again, my fingers easing the gusset of a pair of silk french knickers to one side as they probed inside. With my free hand I undid my trousers and guided her hand down where she pulled my cock out. After a few rubs she moved her bum forward and, pulling the gusset further to one side, guided me into her. She came very quickly with me following very soon afterwards. After kissing agian she said I'd better go as her husband might be home soon. Over the next 7 or 8 months, until I was posted to Germany in fact, we'd fuck ever week or so, then when my posting came through, she decided to make it a clean break. I've often wondered how things turned out for her and hope she found the happiness she deserved. This wasn't the only time I strayed when I lived there. Perhaps more of that later.
