Love is about to begin, but it doesn't start. A platonic relationship with four friends (2 men and 2 women) wakes up as a male and female after an erotic video and gets hooked on a beast-like orgy. A summer memory

Masaru is a cheerful, cheerful, calm Yukine...we were always the same back then. Four childhood friends, men and women, attending the same school, began to arouse sex, and we were in a delicate relationship. At that time, Rino began to say that she would all watch the AV that her older brother had... "I was surprised, and before I knew it, those two had great boobs and bodies." "Their cocks are so hard, are you excited?" From that summer day when we watched the AV out of curiosity, the four of us had sex like beasts.
