邻居的妻子：nao yuuki

"The other day, a couple moved in next door. The wife has big tits and is quite beautiful! The husband seems to be good at his job too. One day, I peeked at the neighbor's wife who left the curtain open to change her clothes... "'Is your husband on a business trip overseas?' The wife is alone for a while... a good opportunity to get close to her! I secretly crawled in the night and cuckolded the beautiful wife! The husband left his wife for work and came to Tokyo. Only her stepmother, who loves to take care of her, comes to help her son-in-law with the housework! It doesn't take long for the mother-in-law and son-in-law, who gradually grow closer as they live alone with their unexpected mother-in-law, to form a male-female relationship. It doesn't take long for the stepmother-in-law and son-in-law to fall in love."
