A Little Neighborly Help: Sex with Mother and Daughter

I masturbate often and I wear a robe at home to make it easier. So when the Japanese woman next door asked me for some help, I said I'd change and be right over. That was when she asked what was under my robe. I showed her and that began us having sex quite often. Then, one day, her daughter asked me if I knew why her mother was so happy these days. I was evasive at first but then showed her what was beneath my robe and now we're all very happy, indeed. And now, if I masturbate at all, it's because they want to watch. How nice is that?
