My wife claims that there is a home video of her parents skinny dipping in their early 30s on VHS. Of course I can't find an excuse to go through all billion tapes to find it. It would be so worth it, though.
A few years ago, well like 10 years ago now, I was helping my friend put her college diving videos onto DVD from VHS. Halfway through one tape, she gasped and turned pure white. She said, "I hope this isn't the one where we are diving naked after practice. I am pretty sure I destroyed that one!" She said maybe we should stop, but I encouraged her to not worry about it. We never ran across the tape of her naked diving post-practice.
I remember we had a home movie that had a great downblouse of my aunt. Well, I remember it being great. I checked the digital back-up of the home movie yesterday because of this thread, and it wasn't that great. You can sort of see something white-ish like probably her bra but can't see anything. Funny how my memory was so off! But, when you are younger and you know something like that exists, your imagination sure can go crazy back then!
