"In the physical relationship between me and my sister ... words are unnecessary" One day my parents remarried ... and my partner's child 'Aoi' came to my house as a sister-in-law. Suddenly she's living with her cute but unrelated sister. She becomes conscious of sex by all means. One day, while my parents were out, I was alone with Aoi... I became more conscious than usual, and when I looked at it, Aoi seemed to be aware of it too... And the two of them remained silent without talking. alone leads to action. The physical relationship between me and my sister that started from there, "If you meet your eyes, you will silently spear like a monkey" began. Also pay attention to "Aoi Kururugi in a short cut" that shows off her cuteness that is different from usual.
