[Reducing Mosaic]JUC-728 Today, I'm going to rape my brother's wife. Honzou Hitomi.

One year into marriage... The wife, Hitomi, is spending happy days with her beloved husband. After seeing her husband off to work, a man suddenly appears before Hitomi as she cleans the garden. "Long time no see, sis-in-law. You're still as gorgeous as ever." The man is her husband's younger brother... and for Hitomi, her brother-in-law, Takeshi. "I barely know Takeshi, but my husband really dislikes him." Though she can't put it into words, Hitomi senses something ominous. That bad feeling starts to become a reality one after another...
