I want to join in the fun and look for a story!

The story in question was one with a couple who go scuba diving (Funky I'm looking in your general direction) and explore a sunken wreck. Then there is a problem with the girl's valve and she blows up. They guy is trying to stop the inflating but she fights him off because she actually enjoys it and I think they end up lifting the wreck and getting very rich off the proceeds.

Ring any bells?
