Mother-in-law Shihou is gentle and warm-hearted, yet hides an alluring pair of massive breasts. She maintained a harmonious relationship with her husband, but their sex life had long been dormant, leaving her sexually frustrated. One day, her son-in-law, who had been secretly aroused by her cleavage, suddenly attacked and seduced her. Claiming, "I can't get excited by my wife anymore because of you, Mother-in-law," he forcefully exposed her breasts, groped and sucked them, then proceeded to creampie her bareback. Overwhelmed by the intense pleasure she hadn't felt in years, Shihou climaxed repeatedly. Despite her guilt, she gradually began secretly deepening her affair with her son-in-law, even as they maintained appearances in front of the family. #Boss P
