Been a long time since I did that but yes I've done it a few times. Having said that these days it's less likely to happen because the Internet doesn't feel quite as secure is it used to, you never quite sure why anybody wants to watch you do that now. But I guess if I got to know somebody well enough I might well.
My wife did that once with a guy I worked with. She was flirting with him via text and she ended up sending him a boudoir picture. He asked if they can video chat. He asked her to take off her shirt. She did and he started masterbating to her. He showed it to her. She thought it was Hot so she took off her pants and masterbated too.
Not sure I would use the paid sites but if I had a good connection with the right person on here or another social site? Maybe if circumstances allowed. I do enjoy taking nude photos of myself and have experimented with using my phone to video myself masturbating. Camming with someone would be an extension of that.
A woman goes shopping in the local mall. But what the heck is she shopping for in that outfit? My Festive Flash comp entry.
