Kobayakawa Reiko, a father-in-law who cuckolds his son's wife with fantasies

I was on a business trip and couldn't get a hotel, so I ended up staying at my son and his wife's house... My son's wife, Reiko, has a lovely smile and has a charming, huge breasts, and is very sexy.

My wife masturbates as if to show off, my wife gently gives me a blowjob in the bath, and my father-in-law's fantasies continue to grow...
