Is that possible? Does anybody have any information on how she might be able to do that. Of course, people would have to want to buy them first.

Please note, I am not trying to sell them on here, but rather find out how the business works.

Use a search engine and look for used/dirty/worn panties. Someone will want to purchase your ladies snatch covers.
Offer some stains to suit and your away.

So whereabouts are you?
I'd love to have a threesome, and then buy them
