Des:Kanon is a neat and beautiful girl who works part-time at a library. Contrary to her intellectual aura, she is a bit sadistic inside. She seduces a middle-aged university professor who has her sights set on her, and serves her generously. She gives a passionate blowjob and squeezes the cum out of her pussy so that not a single drop of sperm escapes. Her joy is to tie up a middle-aged man and play with him as she pleases.
