DLDSS-555 If you don’t move, then it’s not your fault, big brother-in-law. One-sided riding motion by a married woman whose husband pays her no attention. Rika Omi

Five years into marriage, Rika and her husband had a relationship like best friends. She kept telling herself she was happy, but deep down she felt lonely as a woman. Then one day, her husband’s older brother, Yuzuru, came to Tokyo on a business trip and stayed at their home for a while. Even though he was family, having a man in the house stirred something in Rika. Her restless heart and body could no longer be held back. Then, one night, she went to Yuzuru’s bedroom and quietly climbed onto her brother-in-law, whispering, Please don’t move, Onii-san… It’s all my fault alone, as she slowly moved closer to him.
