The only one I can remember off the top of my head is Very Important Perverts (http://community.livejournal.com/mash_slash/229404.html), though I think by mentioning it fits the theme I've kind of spoiled the punchline. Never mind, it's still a fun little story.
Oh, and now I'm thinking about it, there's also Just A Peek (http://tvjunkie1013.livejournal.com/12464.html) (part 2 (http://tvjunkie1013.livejournal.com/12756.html)), which isn't exactly what you specified, but comes pretty close. Edit: re-reading it, I remembered incorrectly; they do get caught in the act in the second half.
Neither of them actually deal with the potential repercussions of getting caught, though - I haven't actually come across many stories at all which really address the attitudes of the times with more than a passing mention.
