Yuichi is in a good mood for staying with his sister-in-law Hana. Hana, who I met for the first time in a long time, had huge breasts as usual, and her eyes were glued to her unintentionally. That night, she happens to see her sister and her husband's activities. The next day, on her way home from her class reunion, she got drunk and couldn't forget what happened last night. Yuichi can't resist the charm of his sister-in-law's plump body, which is not his wife.
