After her daughter's marriage and the arrival of a son-in-law, Kaoru wished for her family's happiness, but following her husband's sudden death, she was left solely responsible for protecting the Shimazu household. However, her son-in-law proved unexpectedly unreliable, and Kaoru's stress grew day by day. One afternoon, while her daughter was out shopping, her son-in-law remained absorbed in video games, doing nothing. Seeing this, Kaoru felt deep disappointment. That night, frustrated that his time with his wife had been interrupted and angry that he was the one bringing in income, he lashed out in rage. Kaoru suppressed her anger, finished saying what she wanted, and quietly left the room to clean. Sensing a presence behind her, she turned around to find her son-in-law standing there. Suddenly, he attacked her. She resisted, but overpowered by his strength, she was forcibly taken. Roughly eaten out, forced to take his hot cock into her mouth, her vaginal walls violently churned, he came inside her right there before walking away. Kaoru trembled in place, yet remembered the pleasure vividly. Later that night, she sat dazed in the living room when her son-in-law approached apologetically, his face full of regret. Cutting off his words, she leaned into his chest, kissed him tenderly, and clung to him like a lover. Earlier that day, when he had assaulted her, she had climaxed repeatedly. The man she had thought weak had made her cum over and over, his burning cock scraping her vaginal walls, stealing her heart with that pleasure. That night, Kaoru took her son-in-law's cock into her hands, gazed at it lovingly, then knelt down and slowly began licking it with her tongue.
