Ever had a screamer?

I remember a couple of years ago I was doing a VIP with a dancer that was giving be an incredible BJ. She wasn't just sucking the hell out of it. She was making love to it. I was so excited that I wanted to take it further and asked about FS. She said that she couldn't ITC because she was a screamer. I didn't know her well enough to try to hook up OTC. So I just enjoyed the BJ.
