The story begins with a joke suggestion from a promiscuous friend: "Why don't you just ask her to introduce you to a horny girl? That way you'll definitely get laid." After having sex, he's introduced to a sexually liberated female friend, eventually leading to an encounter with an "erotic goddess." This time, the woman cooperating with the shoot is Mana, a slender, big-breasted beauty currently living with her boyfriend. She absolutely loves men's nipples and claims to have licked countless ones.
