In the bj vid in my gallery, that was right in front of a big window, didn't bother shutting the curtains or anything. There were quite a few other houses overlooking so anyone could've seen in, but I never really checked, was too busy really. We sucked and fucked quite a lot by that window, and it was quite a turn on knowing that we were probably watched, as we're both a bit exhibitionist. She obviously doesn't mind advertising the fact she's fucking amazing at giving head!!
She told me about a time she'd just started going out with her ex. He was a big fella, and none of his mates believed that she could get the whole python in. She got rather incredibly drunk and when a couple of them were round her house she demonstrated her skill in front of them to prove her skill. She was really embarrassed about that as she said she prefers the thought that someone could be watching, rather than having people actually there.
I was with a girl in college once, and we'd been for a day out in Cambridge. On the way home we got stuck in a traffic jam and she basically got her jeans down, was wearing no knickers, and starting playing with herself. I of course got well fucking hard so she starting going down on me, even though there were people walking past in the street! I got jizz all over her, me and the fucking car, but it was worth it.
My first long term gf and I would often get her house to ourselves on a Friday night when her folks and sister were out. One night we had the music on a bit loud and didn't hear the sister come back in. We were having a great fuck and I was just pulling out and coming all over her tits and face when her sister walked in. (And back out again fairly quickly!)
So yes, I love the thought of being watched, but think I'd be horrified if I actually had people there watching as a true audience!!
