A hickey can be a symbol of love from a boyfriend—or proof of infidelity with a secret lover. In this bold, no-holds-barred project, we'll leave loud, erotic hickeys all over an AV actress's body without telling her a thing, letting the marks spread across her skin before she even realizes what's happening. This time, it's Otsuka Hina, a busy AV star who has a boyfriend and a packed work schedule. After filming, she couldn't show her naked body to her boyfriend and had to cancel all her jobs. Sorry about that! (Laughs!)
