OBA-388 Mother-in-law Nannako Yoshioka drowning in son-in-law's cunnilingus sex

Shinkuro's job-changing activities weren't going well, and he was confused. Furthermore, he asks his wife to be sexless and loves "just cunnilingus", but even that is refused. At that time, his mother-in-law Nanako visits. Shinkuro, who happened to see her and was fascinated by Nanako's clitoris, couldn't stand it and begged her for cunnilingus. Nanako, who has been swept away by her momentum, is squid by her tongue technique that she carefully licks, and she can't stand it alone and sucks on his cock.
