Secretamente masturbándose en las bragas de mi amigo (bragas # 1)

I've intercepted a package that was suppose to go to my friend. She is always getting new panties and lingerie. She has so much, I know she will not miss this package. I'm secretly very jealous of her. So my plan is to try on each pair of panties (there appear to be a dozen here) then masturbate in them. After getting them nice and creamy with my pussy juices I will repackage them and make sure she gets the package looking like it was never opened or tampered with. I can't wait til she tries on a pair of her "new" panties, never knowing what I did to them. Here is the first pair. A pair of full back lacy white panties. Enjoy watching me be bad!
