I am ecstatic that Shizuka Kanno is back, and her cock sucking skills do not seem rusty at all. She is part of the holy trinity of JAV fellatio practictioners, the other two being Yuuno Hoshi and Hikaru Yukino. If she is featured in a Knight's Visual Pacifier Prep production, my balls probably couldn't handle that level of visual stimulation.
Shizuka Kanno, Yuuno Hoshi and Hikaru Yukino (she had as many fellatio-dedicated videos as Yuuno did if not more) would be my holy trinity.
