Voyeurism... What have you seen personally?

One of the hottest things I've ever personally witnessed was a CD in a garter belt, panties, and stockings, sucking off a cock at an adult book store. While some of the booths had glory holes, others had peep holes. I watched that guy enter in jeans, drop them to reveal the lingerie he had on beneath, then he let the other guy in the booth, dropped to his knees, and sucked that cock until it erupted in his mouth. I could hear the guy groan, and that CD was gobbling for all he was worth. Very hot.
About a week later, I got up the nerve to put my cock thru one of the glory holes at that establishment, and was rewarded with the absolute #1 best blow job I have ever received. And it wasn't cheater's head. That person sucked me off. We're talking serious talent.
That was a long time ago. Alas... Time passes.
