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

Although my husband is kind and I love him dearly, his thing is small and weak, so I'm not satisfied with our acts. One day, my husband's older brother, my brother-in-law, stays at our home for a match. Mikan is flustered by the sudden news but is happy to see him again after so long. When Mikan welcomes her brother-in-law in, he says he needs to prepare and heads to his room. When Mikan enters her brother-in-law's room, she sees him in shorts and a t-shirt doing something. It seems like mental imagery training; Mikan thinks, 'No wonder he's a pro.' But then she notices something. His thing is aggressively asserting itself from his shorts. Mikan can't believe her eyes.
