SPRD-519 Your mother-in-law is much better than my wife... Sayuri Takizawa

A husband returns to his wife's parents' home during the Obon holiday and is captivated by the unchanging beauty of his mother-in-law, Sayuri. - The husband loses patience with the sight of his mother-in-law repeatedly appearing defenseless in his field of vision, so he takes advantage of the chance that his wife is out shopping and covers Sayuri from behind so she doesn't notice.
