OVERVIEW
Shinobu was confessed to by Ayame, Kanna and Yuri, then was subject to their non-stop sexual advances. He had planned to choose one of them before the school festival, but he was ultimately unable to do so.
“Ehehe, it’s been a while, onii-chan♪”
One day, his childhood friend Ui returned after moving away when they were still kids. Her parents were originally supposed to accompany her, but they had urgent matters to attend to. Nazuna suggested that Ui stay at Shinobu’s home in the meantime.
“I’m being serious. I’ve always always loved you, onii-chan.
So… have sex with me♪”
She was extremely direct with her feelings for him which had built up over the years they’ve been apart. This was the trigger for the other girls to make even more extreme sexual advances towards him! Surrounded by four girls who are infatuated with him, this is truly a harem situation!
