You know your new swimwear line is going to be a success when you’ve got Chase Hostler‘s ass selling it in a hot vid. Slick It Up is that fetishy underwear and gear brand that serves up fantasy spandex and extremely slutty skivvies. Designer David Mason (you might have seen the now infamous portrait of him as a kinky unicorn) just launched their new swimwear line. While swimwear isn’t exactly underwear, Slick It Up’s bathing suits are colorful and slutty. And you COULD wear them as underwear. Approved!
