Taputapu no Kanjuku Oppai ni Kurumarete, Yumemiru You ni Shasei Shitsuzukeru Ore no Yonpaku Itsuka

Times were hard for the career of a salaried worker.
Shinya decided to enjoy a bachelor's trip to the the hot spring district where he met not one, but three beautiful mature women.

There was the resort owner, the elegant beauty, and the adventurous liberal wife.

He couldn't help wishing to do things deep down inside. When the drunken wife made her move. Perhaps it was the dam of lust breaking free, or his belief that he'd never have another opportunity to taste the perfect ripe breasts of anyone as gorgeous and experienced as this again. Shinya let the wild boar of instinct loose, and run wild in milf paradise.
