Yuri's son has always loved his mother's big butt. He was masturbating by applying oil to her mother's ass who was sleeping because of it. Yuri also has a strong libido, and her daily routine is to masturbate with vegetables in the kitchen. She had it peeked at by her son. One day, for the first time in a long time, my father, who was away from home, came home. The son attacks Yuri from behind so that her mother's ass will not be taken. "Mom's ass is mine. I don't want to give it to anyone!"
