A random rapist spots Ai Mukai on the street and begins to follow her. After the husband is gone for work he knocks on Ai Mukai’s house, who cannot do anything to avoid all the rape coming her way. Eventually, and after a few times. Guilt transforms itself into pleasure, and Ai begins to enjoy it all.
If it isn’t the most recycled JAV plot ever, often with slight variations. Anyhow, Ai Mukai was pretty sweet here.
