我が家の近くに新居を建てる娘夫婦と期間限定で同居生活をしています。娘婿の隼人さんは在宅ワークで一緒にいる時間が長いのですが、ある日真剣な顔をして相談事があると呼びかけられました。その内容は隼人さんのアソコが大きいせいで、娘とセックスレスに陥っているというもので…。日常的に夫から子作りのプレッシャーをかけられていた彼の力になる約束をした私でしたが、想像を遥かに上回る彼の肉棒を目の前にしてしまって…。

My daughter and her husband are building a new house near ours, and we're temporarily living together. My son-in-law, Hayato, works from home, so we spend a lot of time together. One day, he called me over with a serious look on his face, saying he had something he wanted to talk to me about. It turned out that his large penis was causing a sexless marriage with my daughter… I promised to help him, as he was constantly under pressure from his husband to have ********, but when I saw his penis, it was far bigger than I had ever imagined…
