I usually wear double panties when I stream so that anyone who'd like a pair of my slightly worn panties has the opportunity to purchase the ones I was wearing during a stream.. the pair that go on first right after I shower, right before I stream, is for sale so you get the benefit of them having my scent. If I am only wearing one pair of panties during a stream, it is safe to assume that those are for sale. If I am wearing doubles, it is usually because the second pair worn over the for sale ones is part of a set to match the bra or outfit I am wearing.. The pair worn over top is NOT for sale!! The panties you can buy will be worn through the duration of the stream and I can also sleep in it afterwards if you'd like, wearing it until the next day when I take my shower. Or I can take it off any time during the stream, or immediately after. Whatever YOU want. You also have the option of having them sprayed with the perfume that I wear on a daily basis if you'd like!
