Incest sweat: "A hot body, a sweaty uterus, a parent-child instinct that cannot be held back"

A humid room with broken air conditioners. When Haruo returns home, she witnesses her mother Airi sleeping in an unlucky look. Sweat conveys through her voluptuous body. Its so lewd scent was destructive enough to drive young Haruo crazy. Haruo attacks Airi with passion. Airi is confused by her son who suddenly turns into a beast, but Airi, who is naturally perverted and easily sensitive, can't resist the force of her son's cock, which is stiff and angered... The two of them then become addicted to a juice-covered affair.
