NASH-585 What can you do with such an auntie! Even if she's a mature woman (innkeeper/maid/ female guest) who has forgotten about women in a rundown hot spring inn, if she is cornered by a super potent dick in a private room, there's nothing she can do...

In a hot spring inn at the end of the line in Hyakkei no Secret Hot Springs, 13 women including the landlady, maids, and mature female guests are raped while feeling female pleasure. This is a two-part, 12-episode series of mature women touring secret hot springs nationwide. The first part takes place at a hot spring inn deep in Hokkaido, where customers from Tokyo sneak into the room of a fifty-something maid with huge breasts and are raped next to her husband, while a landlady in her sixties who habitually evades taxes is penetrated by multiple men by a customer disguised as a tax official, and so on, in three episodes. The second part consists of nine episodes featuring 10 mature female guests staying at secret hot springs nationwide being raped in an orgy.
