Kanone Kanon's first attempt at the popular series! Kanon teased his unpopular virgin brother as a joke. The younger brother, who mistakenly thought he was actually tempting him, immediately inserts his dick into his sister, right after his parents left. Kanona has reached orgasm due to the great momentum, but her younger brother, who is not used to women, does not notice and ignores her and continues to shake her hips in a slut.
