SPRD-825 Mother-in-law, you're so much better than my wife... Natsuko Kayama

It's the weekend. Shintaro, a hardworking young office worker who lives with his wife somewhere in Tokyo, has a rare chance to take a long vacation, so he and his wife decide to visit his wife's parents' home. It's a three-hour ride on the Shinkansen and trains from Tokyo. When they arrive at a Japanese-style house in a medium-sized city undergoing moderate urban development, they are warmly greeted by his wife's mother, Natsuko Kayama. The stepson can't help but gulp at the sight of his mother-in-law's voluptuous curves.
