This is based on a true story that happened to my ex-wife and I many years ago.
Going back 15 to 20 years ago when I was still married to Lara the first class train carriages had individual compartments that would seat 8 people, these compartments were separated from the corridor by 2 windows and a sliding door.
My ex-wife is called Lara and she was a stunner, she would turn heads when she walked into a room, I know I was punching well above my weight. She is about 5 foot 9 inches, long blonde hair, small but perfectly formed breasts with large sensitive nipples, a flat tight size 8 stomach leading down to her beautifully shaved cunt all held up by her long shapely legs.
One day we were talking about things we wanted to try sexually and I said I wanted to fuck on a train, Lara was well up for this and we started to make our plans, we checked out which train would be quiet with the right carriage and set the date for the following Thursday.
The following Thursday afternoon Lara started to get ready, she showered and freshly shaved her cunt and when I got home from work she was already upstairs getting ready. By the time I got out of the shower Lara was ready, wow I wanted to bend her over and fuck her right there and then but Lara told me to be patient. Lara was wearing a short tartan wrap around skirt, a very thin tight white blouse that clearly showed off her black bra and a black pair of fuck me boots.
