Ema visits the family home where her widowed father-in-law lives after paying respects at her husband’s mother’s grave. That night, he witnesses the couple having sex and resents his son for finishing without satisfying her. The next day, while Ema is cleaning, he approaches and claims he can make her cum repeatedly. She resists at first, but after his stamina drives her through orgasm after orgasm, pleasure begins to conquer her.
