MOND-140 The sister-in-law who was completely smitten by her brother-in-law, Mikakan Sumiki

My husband is kind and loves me, but my wife Mikan who is not satisfied with her actions because she is small and weak. One day, her husband's brother, her brother-in-law, is staying at home for a game. Mikan panicked at the sudden incident, but she was happy to see him again after a long time. After welcoming her brother-in-law, he went to her room to get ready. When Mikan entered her brother-in-law's room, his brother-in-law in shorts and a T-shirt was doing something. She seems to be an image trainer, and Mikan thinks she is a professional, but she notices something. She is asserting herself violently from shorts. Mikan couldn't believe her own eyes.
