I share a room with my childhood friend (Shin-chan) at a hotel after returning from an event in Tokyo, which has become an annual tradition... - When Yui learns that things aren't going well with her, she confesses that she's been secretly in love with her for 10 years. - A closed room with just the two of us... He can't control his reason and gets fully erect due to the temptation of the cute Yui! - Yui, who has a delicate and small body, gets nervous and cries many times! - "Can I cum inside you?" 10 years of feelings overflow and an unparalleled sexual intercourse that ejaculates 9 times until morning!
