I had an orgasm recently when an oldish guy was rubbing his thigh against me. That's done it for me before, when we're wriggling around and I've rubbed myself on their thigh
I don't think to do that often but thinking about it makes me horny. How strange.
Sometimes when I've had one with someone I don't fancy, I wonder if it's because they're so unlikely to be ones I'd go with outside the job that it makes it seem more taboo and that turns me on
, the dirty old man types but again the touch has to be right. It's not often that happens though.
