3DSVR-1915 Completely Dominating the Arrogant Sisters with a Cicada-Like Stimulant

I was laid off from a company in Tokyo.
With my savings gone and nowhere else to go, I found myself stranded in the summer heat. I could no longer even afford the electricity bill for the air conditioner, so I decided to move in with my older sister, who lives in the countryside.

At my sister’s house were her two daughters, both in the middle of their rebellious teenage years.
The quiet and sharp-tongued older daughter, Rina, and the younger daughter, Konatsu, whose emotions are easy to read.

There was no way they would warmly welcome their suddenly unemployed uncle, and so a gloomy summer vacation began for the students and the jobless man alike.

Then one day, a cicada appeared in the garden. Even if touched or placed in a bug cage, it would not fly away, and it kept chirping persistently. Each time that sound echoed, something began to change in the sisters.

They grew restless, drawn toward masculine attention, and became increasingly obedient. Just like the cicada, excited to leave behind the next generation during this summer.
