A mini-sized Tsurupeta sister. Kurumi is cute like a small animal. A story of a dense and immoral love that unfolds in a closed room between a lovely little sister and an older brother who loves her but is too distorted. Every day, the older brother was suffering from growing feelings and desires for her sister. The older brother, who found the only way to release the pain, put his hands on her sister who was looking at her with an innocent expression. Her blocked desire surged like a muddy stream and swallowed her sister and sank into the depths of pleasure with her brother.
