I can wear them for up to 9 days. When I go jogging, I can sweat them wet. You get my orgasm in my panties as an extra perfume. You can get caviar and/or golden showers. Since I am sexually aroused very often, I would be happy to satisfy myself in them. Inside or/and during sex, take your pick. You can get menstrual panties after a certain waiting period, as I don't menstruate every day, but when I do, it's extremely heavy and intense. Vacuum-packed panties can be yours...exciting thought for me ;-)
