Many Japanese dramas or mystery films start with the remarriage of parents. It is really easy for unrelated sisters or brothers to stay under the same roof for a long time and fall in love with each other.いつか女に情してしまう. だから女から出げたのに" is the best example.

In the film, our male protagonist, eight years ago, his father remarried, and he and Shishido Riho, though not related by blood, became family. It was once a happy family; however, without realizing it, the male protagonist slowly fell in love with Shishido Riho.
At first, he only saw Shishido Riho as a little sister, but as her breasts grew larger and her figure improved day by day, the male protagonist gradually began to see Shishido Riho as a woman. Fearing that one day he might do something inappropriate, he decided to run away from home.

The male protagonist uses his busy university life as an excuse to escape his darkest desires. Time flies, and before he knows it, a year has passed since he last went home. Just as he musters the courage to step through his door, wanting to surprise his family, he discovers his father sexually assaulting his younger sister.

It turns out that without the male protagonist's protection, it was actually his own father who couldn't resist and committed a heinous act against his sister. Witnessing this incestuous scene, the male protagonist, for some reason, felt not anger but rather an unusual excitement, and continued to violate his sister after his father. Like father, like son!

Title of the work: まさかfather さんが sister をcriminal していたなんて…. いつかServant は sister に lust してしまう.だから sister からescaping げたのに.
