Kazuya, a son-in-law who lives with his wife and her parents, retired from work due to excessive stress and became unemployed. The harsh words of his father-in-law pierce Kazuya... However, in contrast, his mother-in-law, Rui, envelops Kazuya with Buddha-like kindness. Kazuya helps out with the housework during the day, but what catches his eye is Harui's too big boobs! Kazuya quickly regained the vitality and energy that he had lost, and inflated Rui's distorted desire for big breasts.
