Kanon is a beautiful girl who works part-time at a library. Despite her intellectual appearance, she is a bit sadistic on the inside. She seduces the middle-aged professor she has her eye on and serves him to the fullest. She gives him a passionate blowjob so that not a single drop of sperm escapes, and milks his sperm with her pussy. Kanon finds pleasure in restraining the middle-aged man and playing with him as she pleases.
