Hajimete no Orusuban

Based on the erotic game developed by Zero, Hajimete no Orusuban follows the story of Shiori and Saori, twin sisters who share a secret infatuation with the young man living next door, whom they affectionately call their older brother. As the girls grow older, they begin to develop a deep curiosity about intimacy and romance. Eager to explore these newfound feelings, they quietly resolve to have their trusted neighbor teach them everything they wish to know, setting the stage for a summer filled with temptation. When the season changes and summer vacation arrives, the twins' mother departs and entrusts the young man with watching over both the house and her daughters. With endless days of free time stretching out before them and no parents around to supervise, the three are left entirely to their own devices. What begins as a simple request to look after the household quickly transforms into an opportunity for the sisters to act on their hidden desires. As the long, warm days unfold, the boundaries between innocent house-sitting and something far more intimate begin to blur, leaving everyone involved to discover just how exciting looking after the house can truly become.
