Whats the average ammount of time you like a pair of panties to be worn for?

I like them to be as dirty as possible. Trouble is the wife doesn't really want to wear the same pair for over a week! She's willing to wear a pair for 3 days if I nag really her, but anything more and she refuses!

I've found a way around it though. When she's not around I'll take a soiled pair from the washing basket and put them back in her underwear drawer!

So far the 'spunk dustbin' hasn't sussed out my stealth aproach. Its good to have finally found a use for all that army training!

as long as possible, ie 7 days, PLEASE!
