If you look at Rui-sa Kotsuki's SNS, it's immediately clear that she has a body so toned that even women support her. She trains and researches beauty daily to maintain herself, living a life with the consciousness of a supermodel. She also has high awareness towards sex, and the same goes for her job in AVs. I've never encountered such loving god-level blowjobs and a well-trained godly tool. Her personality is bright and charming as well. She's undoubtedly number one.
