[JUQ-089] Mother-in-law, I love you so much, sleep with me tonight.

An incestuous sex movie by Reiko Kobayakawa… The daughter and son-in-law wanted to save money to buy a house, so they moved in with their mother-in-law. Reiko used to be a photo model, and she didn’t know that her son-in-law was a fan of hers. One day, Reiko accidentally discovered that her son-in-law was watching a sex movie with an actress who looked a lot like her, surrounded by photos of her when she was a model. He was using her photos to masturbate! The son-in-law’s huge dick made Reiko unable to take her eyes off him. It turned out that because the dick was so big, it hurt Reiko’s daughter. It had been a long time since her son-in-law had sex, so he had to “take care” of it alone. Feeling sorry for her son-in-law, Reiko decided to offer to “take care” of his big dick instead of her daughter. At Reiko’s invitation, plus the fact that he had suffered for so long, he couldn’t resist anymore….
