While scouting for photo models around Takadanobaba Station, cameraman Tei approached several girls before finally convincing Mayu, a shy girl who agreed to a shoot at the studio. They quickly headed to the studio, where Tei began photographing her while chatting about her background. Mayu is currently a university student majoring in business administration and hasn't had a boyfriend for the past two years. Her large breasts are clearly visible even through her T-shirt, and although she seems surprised when Tei points it out, she admits, "My big chest has always been a complex." However, after showering her with compliments and persistent negotiation for higher pay, she finally agrees to the shoot. Insisting that if he's shooting her breasts, he must also photograph her lower body, Tei offers additional payment, hands over the money upfront to gain her trust, and successfully captures shots of her in panties. This smoothly leads to physical contact, and although Mayu initially resisted taking erotic photos, she surprisingly accepts the touching without much resistance. Her breasts spill out of her bra—beautiful, large tits with prominent pink nipples. When Tei fingers her pussy, she moans softly, clearly turned on. Before long, he successfully penetrates her, and as she writhes with her jiggling breasts bouncing, he cums on her face with a cumshot. Although the session escalated all the way to sex, Mayu appears to have enjoyed it, leaving the entire shoot with an odd, indescribable atmosphere.
