The younger brother had just gone on a business trip for a few days when the bastard father became angry and wanted to rape his beautiful daughter-in-law, Makina Yui. Having been stalking her since she first came home, her husband was working far away on the day she was dressed too sexy. Realizing that the opportunity had come, he did not hesitate to rush in, pin her down and rape her. Even though the sister-in-law knew it was incest, partly because she had long lacked her husband's affection, partly because she was just as lustful as her father-in-law, she had to silently "bear it". Next are the sex positions and very exciting and attractive sex between the two.
