My wife and I like to go on Omegle (well, clones of Omegle I guess) and put on a show. We don't do it often, but when we do it's incredible. We always finish together, but sometimes I watch the screen while she plays.
Last time we did it I was behind her fingering her pussy but was off screen, and she told a guy she was being fingered but he didn't get it - she showed him her hands, and he still didn't get it. He asked if she had a toy - No, I'm being fingered! He still didn't get it. She had to tell him I was there, and once he finally understood he left the chat so fast. He could have had an incredible free show, but chose to look at a bunch of dicks hoping for something else. Who does that?
Anyhow, here she is showing someone that I blew my load in her mouth.
