You choose my underwear from an online retailer and send me a link to it. You transfer the money to buy the underwear (including any postage), I order it and then wear it for a day (or longer if required) and then you pay me the wearing costs and I send it to you for your enjoyment. The deal can include photos of me wearing the underwear. Remember, you can choose whatever underwear you like, cheap, expensive, sexy, classy, silk………. Your choice.
