3DSVR-1915 - [VR][8K] Complete Domination of Impudent Sisters by Cicada Sounds

I was laid off from a company in Tokyo. My savings ran out, and I lost my place, it was summer. I couldn't even afford the electricity bill to turn on the air conditioner, so I decided to move in with my sister who lives in the countryside. My sister's house has two daughters in the middle of puberty. The taciturn and prickly eldest daughter, Lina, and the younger sister, Konatsu, who easily shows her emotions. They wouldn't welcome the suddenly appeared 'unemployed uncle', and a gloomy summer vacation for students and the unemployed began. One day, a cicada appeared in the garden. No matter how much you touch it or put it in a bug cage, it doesn't run away and keeps chirping persistently. Every time the chirping sound echoes, strange changes begin to appear in the sisters' behavior―――. The sisters become restless, are led to seek a 'male', and become obedient. Just like cicadas eager to leave offspring during this summer.
