I drifted off as my need for sleep outweighs my curiosity.I woke again this time to the rustling of someone moving around in a nylon sleeping bag. I l...oked over towards my wife to see the 12-inch gap between them had disappeared. He was lying right up against her back with an arm around her waist. I sat quietly not sure what to do. I watched as he slid his hand up and down under the covers feeling up her leg and rubbing her ass. After a few minutes I noticed her body start to respond to his. Leaning against him she felt the warmth of his breath, and melted from his touch. ‘This is going to be wild.’ She thought, and then his hands were brushing her breasts, kissing her neck he felt the nipples stiffen to his touch…….She was whispering his name and other things in French….’I have to learn that language,’ he said to himself. She moved away from him and smiled. ‘I just said that it was time for the boudoir.’ Then as she turned he saw her reflection in the mirror, as she demurely. On the afternoon train he ran the control room on the other end of the train. I sat there, making myself wetter and wetter, thinking about riding his cock while he was driving the train. I have to get a hold of myself i thought. I was going to regret wearing the black mini skirt and thigh high fishnets I had on if I kept making myself so wet. However, as the minutes past, I couldnt stop thinking about my mouth tightly wrapped around his prick. It got to the point where I just couldnt take it. She asked me if I wanted something drink I said yeah and I followed her up the stairs where I could see her whole ass swolling a tiny g string. I wanted to take a pic but didn't wanna ruin everything. So once I was upstairs I sat on the bed. She stood infront of me between my legs. Shoving her titties in my face and grinding her ass on my dick. She asked me if I was gonna take my pants off which I did very quickly. She started to stroke my dick so I was fingering her pussy. Then she layed me on.
