In a room filled with the sound of cicadas, a fan oscillates back and forth. Kana is focused on studying at the table. Then, an uncle in grimy work clothes returns home.
"I'm home."
"...Welcome back."
"What's this? Studying?"
"...Yeah."
The uncle stares intently at Kana. From the viewer's perspective, this is the moment when this ordinary daily life begins to warp.
"Kana, have you grown a bit taller?"
"..."
"Stand up for a second."
He makes Kana stand up, then strokes her head with his palm.
"What's this? These have gotten bigger too."
He suddenly starts groping her breasts.
"With these, the boys in your class wouldn't leave you alone, right? Have they already groped you?"
"..."
"I'm tired from work today. Give me a massage."
The uncle abruptly takes off his work clothes and pants, lying face down. He gives Kana instructions and makes her massage him. Without saying a word, he buries his head under her skirt.
"Smells good. I'm getting hard."
He stands up, pulls down his underwear, and shoves his erect dick in front of Kana's face, making her lick it. This distorted daily life unfolds on a summer day.
