Beautiful sisters Ayana and Hikaru, working at a major seed company, are ensnared in a group of men's cunning scheme and reduced to mere playthings. From forbidden lesbian acts—forced to lick each other's nipples and crotches—to extreme breast torture involving tight bondage and suspension, they are given no chance to resist. Their pure bodies are completely defiled by the men's hands, as this relentless series of brutal acts gradually takes total control over the sisters' minds and bodies.
