His virgin brother, who took his sister's provocation seriously, is not aware that he is cumming and runs wild.

Akane, who teases her unpopular younger brother, immediately goes out to her parents, and her dick is inserted immediately after her parents go. Akane gets so excited that she doesn't notice it, but her younger brother continues to shake her hips. Even after climaxing, she orgasms repeatedly with the pleasure of the thrusts, and her resistance is irritated and she continues to cum over and over until her parents return home. The second installment of the popular series in which her sister screams, "I'm cumming already!!" completely ignores her and makes her climax with a thrust in a thrust!
