Meeting with the director on a street corner is Yuri Adachi, a seemingly beautiful young woman who masturbates every day! She's handed a sign that read, "Looking for someone to make me cum!" Adachi's greedy nature is such that she's been selected for the role, knowing she'll find a suitable partner among the amateurs on the street. Holding up the sign, which draws the attention of passersby, Adachi finally manages to get her first man. She then wraps her arms around him to prevent him from escaping, successfully entering the studio! Her masochistic side is stirred by the man's enjoyment as he sniffs her newly removed NuBra and panties, and she takes a liking to his pre-cum-filled dick, meticulously licking it from balls to head! She encounters a perfect dick that's so addictive she's hooked. After being pounded from behind, she reaches a breathless climax, proudly holding up a condom full of sperm! After causing a second amateur man to ejaculate prematurely with a handjob, Adachi becomes deeply depressed and decides to masturbate to relieve his stress and change his mood... A sudden, unscripted plan is put into motion to let Adachi's sexual desire, which has been left unspent due to the unexpected incident, explode to his heart's content. A veteran actor disguises himself as an amateur and blends in with passersby. As expected, Adachi, alertly aware of the male hormones, rushes over and successfully enters the studio without revealing his identity as an AV actor! The actor sits on the bed, grabs Adachi's hand, and closes the gap, completely changing the atmosphere on set. Adachi, who is perceived as a 'masochist' by a supposed amateur man, is dominated by pain and agony, and her face is filled with ecstasy! When he pounded the back of her throat and vagina with a massive dick, she wets herself profusely and orgasms repeatedly, revealing her true masochistic nature!
