Sara, the older sister-in-law, is fed up with a husband who's always away on business and does nothing but masturbate. Himari, the little-devil lesbian younger sister-in-law who's come to live with her, seduces her sexually frustrated sister-in-law. The married woman's sensitive nipples on her huge breasts hit peak arousal under her sister-in-law's tongue. When she kisses her melting pussy, a flood of dirty juices pours out, and while the husband is away — forbidden lesbian sex. A netorare (cuckolding) story of two huge boobs pressed tight together.
