JUQ-089 Reiko Kobayakawa is invited by her mother-in-law who wants her son-in-law's big dick all the time.

One day, Reiko, who lives with her daughter and her husband, witnesses her son-in-law Hikaru masturbating out of frustration. Reiko couldn't take her eyes off that huge thick dick... As soon as she finds out that the reason is the lack of sex with her daughter, she plays with his cock and continues to seduce him, saying, ``I'll take her place.'' Hikaru, who has been accumulating sperm on a regular basis, should be able to resist such an invitation from his girlfriend's mother-in-law.
