A week of parents absent... [Born overseas and open to sexuality] Always half-nude half-Japanese sisters and my own big breasts live together.

"Idiots! We're siblings." "My brother in law. It's legal." When a shitty father remarries, two beautiful half-Japanese girls end up having two shitty dad remarried. Her older sister, Rika, is a classmate. My younger sister Karen is one lower. Perhaps because they have a long time living in a different culture, it's only natural that they are naked in their room. They were very curious about my crotch, which was so encouraging. Three days were the limit to suppressing adolescent sexual desire. When we learn the joy of sex at school and at home, we continue to have sex.
