My mother-in-law, Miyu, has a natural and self-paced personality, and was treated by her husband as dull on a daily basis. However, Miyu is the owner of her huge breasts, and her son-in-law Nobu was secretly interested in her breasts. Nobu approaches Miyu saying, "It's a waste if you don't use such nasty boobs," under the guise of reconciling the couple, and begins to play with her big tits. Miyu, who doesn't notice Nobu's intentions, is repeatedly made to go, and if she notices, she will drown in domestic affairs with her son-in-law, leaving her husband and her daughter behind.
