Akari Neo, a childhood friend who cannot be honest, attacks her boyfriend with an impeccable butt! Akari, who has been by my side since I was little, likes Kenichi, but I can't honestly say that. One day, the air conditioning in the room broke down and Akari naturally came to cool off in Kenichi's room, but when Kenichi found out that she could do that, he was very shocked. However, Akari, who cannot back down here, tries to sway Kenichi, who loves butts, in an extreme style.
