I had to travel recently by train and I saw something quite arousing and unexpected when I did. Anyone that’s ever traveled by train can tell you there’s a lot of vibration and rocking motions, especially in certain areas. When I was getting on board I was waiting for people ahead of me to sit down and I rested my hand on this metal bar and it was vibrating a lot and I smirked and thought it would be good for an orgasm, but of course you can’t do that on a train in public.
It was a few hours long ride and not too many people were on board and when things quieted down I was on my way to the food car and had to walk through an area where there were a few private rooms on each side of the corridor and there was small curtain like things over the glass on the doors, but it wasn’t pulled all the way closed and I looked in and saw a woman pressing herself up against that vibrating metal bar thing and I knew exactly what she was doing. I stood there and watched her through the crack in the curtain and no one happened to be there so I was able to stand and watch and her skirt was up around her hips and she had her panties on and she was clearly enjoying the vibrations and I could tell from her biting her lip she was about to cum.
I was honestly getting aroused watching her and felt myself getting a bit wet, but I had no private sitting area behind a door to get myself off in, but I watched her and she came and then soon straightened herself up and I walked away since I didn’t want her to know I’d been spying on her masturbating, and I wondered how many others over the years had found a good use for that vibrating metal bar. I’d bet quite a few.
