In the Married Woman Pussy Encyclopedia series, Izumi Shungu is a married woman who, unfulfilled by her ordinary life, turns her desires toward men other than her husband. Previously unaware of orgasm, she becomes highly sensitive to finger penetration, drenching her dripping wet pussy with lubrication as she's relentlessly stimulated by a thick, twisting vibrator, driving her to climax. Then, two fingers are deeply inserted into her slippery, juicy slit, targeting her G-spot and leaving her writhing in ecstasy. This work explores a married woman's yearning for new pleasures, igniting fantasies of mature, well-used cunts explored with fingers and vibrators.
