"Secret Filming" is a new way of filming, where the girl secretly "hidden filmed" so that she doesn't notice she's being filmed, allowing her to concentrate. This allows the ultra-rich Nozomi Aso to show us her true expressions, which are 98% private, and her true nature, which is 100% lewd, that she has never shown in previous AVs. Four intense scenes where they "seriously" desire each other and get wild from the bottom of Kokoro!
