A few weeks ago I had to take the bus home after getting off work late at night. When I got on the bus there was no one there (this was pretty unusual). I decided to sit in the very back of the bus (it was a very long and stretchy bus).
Halfway through the ride (it's about an hour ride) it was still just me and the bus driver, who was way at the front of the bus. I don't know why, but suddenly I just became really horny; having all kinds of naughty thoughts. I eventually became so horny that I couldn't stand it anymore.
There was still no one on the bus, so I decided to slide my hand up my (very short) skirt and start rubbing myself through my panties. Never having done anything like this before, I covered my lap with my jacket, just in case. It felt soooo good, and I was only rubbing my pussy lips through cotton. Still no one arrived on the bus, so I decided to take things up a notch.
I was already so wet by this time, that I decided to finger myself right off. Just a little teasing at first, but then I started to build the momentum. (It was so hard trying to keep from moaning). I could feel my orgasm nearing, but I wanted to prolong my pleasure a little more (I still had about ten minutes left).
I started rubbing my clit, softly at first, but that didn't last long. I rubbed harder and harder, my thighs were trembling at this point. I was so wet, it was soaking my skirt. Finally I gave my swollen clit a little twist and a pinch, and my orgasm screamed through me, my juices soaking the seat. It was the best orgasm I've ever had. A few minutes later we arrived at my stop. I exited the back door, and rushed home, eager to have a bit more fun.
