## Description
"I want to rape my younger sister"

Older brother Tomoyuki and younger sister Rinne are ordinary siblings. They live like normal, get along and fight like normal. But she has become the object of his desire and each night he sneaks into her room. Again and again he masturbates to her sleeping form as she lies there defenseless.

This summer they're forced to spend more time together. She's grown more delicate, her arms are softer, her hair is growing longer. His sister, like a sweet flower that's begun to open up and bloom, is becoming a young woman. The summer sun shines brilliantly now and sweat trickles down her neck from the heat.

When he closes his eyes he sees her smile up at him. He cannot suppress his lust any longer.
