Mariko, a girl working at a cake shop, applied to appear in an adult video. The staff contacted her and went to the cake shop where she works, where she was on duty. Looking at her working in an apron, she doesn't look like the kind of bold girl who wants to appear in an adult video. The staff called her to a nearby park, talked to her about various things, and decided to have her appear in an adult video. The staff was particularly interested in her gigantic breasts, which exceed an H cup. There is POV, swimsuit cosplay, and threesomes, and all kinds of bold play is undertaken to bring out her erotic side.
