Kanone takes on the popular series for the first time! Kanon teases her unpopular virgin brother as a joke. The brother thinks she is really trying to seduce him, so he inserts his penis into his sister as soon as their parents leave. Kanon climaxes with such force that he climaxes, but the brother, who is not used to women, ignores her and continues to thrust his hips recklessly. Even after he climaxes, the pleasure continues to chase after him, making him climax again and again, and despite his resistance, he is made to cum over and over again until his parents return home.
