## Description
The protagonist has a younger sister named Saki. She’s cute, great at studying and excels at sports… pretty much the perfect sister. They aren’t closer than any normal siblings would be. It’s not like he’s a siscon nor she’s a brocon, or at least that’s what he thought. He wondered if he should fall in love with someone, perhaps his older sister-ish childhood friend Izumi, her baby-faced but big-breasted younger sister Mizuumi, or maybe Saki’s cheeky tsundere best friend Yui. But something seemed to be missing. Something that, unbeknownst to him, had always been close to him.

## Characters
### Hiraki Saki (平木 咲姫)
A perfect face. Good grades. Good at sports. Aah, she's almost like a perfect little sister! Well-known throughout the school. Is also a member of the Tennis Club. Despite all this, Saki is actually a brocon who lusts over her brother. Like her brother, she has a fetish regarding body parts, and that's finger fetish.

### Nanaze Mizumi (七瀬 湖)
