It was probably one of the signal lights indicating another train may be up ahead. The person behind her moved forward as the train came to a stop. Th... contact with her ass continued.With the train at a stop, Sonja's mind focused on the contact with the person behind her. It was almost as if... There was movement. Whatever was touching her ass moved slowly down and then back up. Almost like a caress... as if it were... That was no thigh! Whoever was behind her had his hand on her bottom! He was. I knew my wife had an Ann Summers party booked for a Wednesday and her friends and our neighbours were all expected to attend, along with the party organiser, Adele.On that Wednesday out of the blue, I arrived back in the area and needing a shower etc I decided to go home.I arrived home just as the party was getting lively and was not received very well by my wife. It is against the rules of the party for a man to be present. I said my hello's and made my way upstairs where I showered, then lay. I hadabout another hour so I switched on the radio poured myself another glassof wine and lit a cigarette. Settling back to enjoy the last part of mylittle adventure, before changing back to my rather boring male attire.After about ten minutes I thought I heard a noise outside warehouse, no Imust be imagining it I had told the guard I was working so it would notbe him. Must be my imagination, no there it is again. I got up and movedtowards the door of the office. Oh god this can't be happening. I began to slide out and in, out and in again and again until with a final heaving thrust, deposited my spunk in hot gushes as far into her as I could then continued to rut with her until my cock became flaccid and plopped wetly out of cunt; sliding down to and over her bum hole followed closely by a mixture of fanny juice and sperm that dribbled over and between her cheeks before puddling on the sheets.Soon after we cleaned-up and began to shave her of her stubble. She remained with her knees.
