Summer House: Perverted Siblings’ Hot Summer Days

Synopsis

Several months into living alone, the protagonist’s younger sister comes to stay for about a month while preparing for her entrance exams.

However, the protagonist’s feelings are conflicted. He harbors a secret—the real reason he moved out alone was to distance himself from his sister.

Unaware of his complicated emotions, his sister arrives innocently delighted. Under one roof filled with complex feelings, the defenseless sister eagerly embraces the summer season.

――This summer, the siblings’ hidden desires spiral out of control…!

An H love-comedy RPG where you interact with your visiting sister over the course of approximately one month.

●System

An RPG-style game spanning about one month, with each day divided into 7 turns (2 morning/3 afternoon/2 evening). Events occur between each time period. Moving between the hallway and individual rooms consumes one turn.

You control the protagonist (older brother) and progress by making contact with your sister through various events, enemy encounters, and minigames. Your sister’s “lewdness level” increases through conversations and events, with her behavior changing accordingly. Multiple endings vary based on your choices.

Previously viewed movies can be replayed anytime from the title screen. Rewatches can be skipped for faster progression.

●Battle

There’s no experience system, but defeating enemies grants points to allocate to the protagonist’s stats. Enemies appear randomly in each room as symbol encounters, allowing optional battles. Low stats may make battles challenging!
