A book about an older sister and younger brother who don’t get along so much and copulate like monkeys in heat.

“The older sister who is concerned about her younger brother’s body" and “the younger brother who is concerned about her older sister’s body" are just mating!
◆◆◆Synopsis◆◆◆
The two orphaned siblings were taken in by the village chief of a marginal village in a remote rural area, and were doing well in school.
It was soon discovered that the two had a unique constitution that allowed them to produce extremely healthy children in a short period of time without any burden between siblings!
The village chief sees this as an opportunity to increase the population and seduces his older sister Aki and younger brother Yu, but as soon as they do, a storm of anger ensues.
Yes, the siblings didn’t get along well.However, there is a plump older sister in the prime of adolescence and a younger brother with a big cock.
Strong sexual desire, great physical compatibility, under one roof, nothing can happen…
