The end is decided by a fierce wife vs. fierce mother-in-law! A serious lesbian battle between a wife and a mother-in-law who are as far apart in age as a parent and child at home! We visit a house with a mother-in-law/daughter-in-law problem, and the lesbian battle is decided by betting on the leadership of the house and 1 million yen of war funds! The wife attacks acrobatically with her youth and physical strength, while the mother-in-law attacks sticky with mature techniques... It's exciting to see them devour each other's pussies, overcoming the age difference and physical gap!
