Rei teases his unpopular younger brother as a joke. Immediately after her parents went out to her virgin brother who misunderstood that she was really inviting herself, her cock was inserted immediately. Rei cums with too much momentum, but she doesn't notice that her younger brother, who is not used to women, keeps shaking his hips. She repeats the climax many times with the pleasure of the piston that continues even if she cums, and her resistance is in vain and she continues to be squid until her parents come home.
