[Novel/Novel]
The main character, Seiichi Miyake, has a twin step-sister from his mother’s remarriage. His older sister Rin and younger sister Ran.
Lately he has been troubled by the actions of these two. Because he seduces me with tricks and dirty jokes.
Rin will approach you through direct contact, and Ran will approach you using her words and strategies. It’s troublesome because these two are teaming up.
Still, Seiichi felt relieved. That’s because it’s home and my parents are there. I thought he wouldn’t do anything shameful at his parents’ house.
However, things suddenly change. His father was going on a long business trip, and his mother had to accompany him.
Seiichi’s parents also agree that there is no problem living with the three of them, and Seiichi’s chastity is finally in jeopardy.
While Seiichi’s siege is gradually narrowing, Seiichi also likes Rin and Ran. He then confesses that he has been worried about what his biological father did after abandoning Seiichi, and that he thinks he can’t touch them.
Ran comes up with an accurate answer. By doing so, there were no barriers between Seiichi and his sister-in-law.
Seiichi, who thought he was stuck, was guided by his two sisters-in-law and ended up committing the act. However, it wasn’t the stairway to heaven…
