DBZ fanfiction?? Help me find this one story!!?

Ok so, a long time ago, I read this fanfiction. I don't know where I read it! LiveJournal, Angelfire, Fanfiction.net?? But it involved Goku/Chi Chi, Gohan/Videl, Vegeta/Bulma and a bit of Krillin/18. They had a competition between the couples to see who could withstand from having the longest. It originally started out with the girls challenging one another but then the guys found out and decided to have a little fun and test their limits. And Goku/Chi Chi were the first ones to cave whereas Gohan/Videl won the whole thing. Does anyone remember it? If so, can you link me??? PLEASEEEEEE! I can't find it anywhere!! It was soooo awesome and funny!!
