Sexy, big-breasted Mitsuko leaves Tokyo with her husband to live with his ailing father and his father’s young, hot wife. Mitsuko brings her father-in-law medicine, but he has his own remedy to stay alive ? making Mitsuko his live-in sex slave! He says during one encounter: “Simply licking off your sweat at your armpit makes me feel younger.” You just don’t get that kind of dialog in mainstream films.

Mitsuko tries to thwart her father, but always fails and succumbs to his gigantic cock. It isn’t long before her brother-in-law catches them having sex during a BDSM scene involving some paintbrush tickling. When the father leaves to rest, Kouji takes advantage of the situation and before long exclaims, “I’m in my sister’s ass!”

Retailing: Taboo hentai style!
