STARS-972 Horny Office Lady Caught Masturbating And Blackmailed To Fuck By Her Senior
STARS-972 Goro manages a laundromat, and one day, he discovers Mei Miyajima alone in the laundromat, masturbating, getting aroused by the vibrations.
He threatens and blackmails her with the footage in exchange for sex favors, but very little convincing is required as Mei is a full-blown pervert, to begin with.
