Masaru is cheerful, cheerful, quiet Yukine... We were always together back then. Four boys and girls who are childhood friends who go to the same school. At that time, Rino said that everyone should watch the AV that his older brother had. "I'm surprised, those two have nice boobs and bodies" "Your penis is really hard, are you excited?" From that summer day when we watched AV out of curiosity, the four of us went crazy like beasts.
