Widowed at a young age, Minami Fujii is desperate for affection and sex. When her brother-in-law offers to help with anything she needs, she abruptly pulls down his underwear and drains him with rapid vacuum oral sex in front of her late husband's memorial portrait. Once she slips out of her mourning clothes, her pale, mature body overwhelms his restraint. He pounds her as she commands, making her cry out and climax repeatedly in broad daylight. Being taken by the brother of the man she loved fills her with guilt, but after so long without sex, the widow abandons herself completely to lust.
