A 25-year-old office lady named Yui, living in Tokyo, has been given the opportunity to experience pleasure after four years of abstinence. She seems both nervous and excited about her first time having sex, but she does have some experience with sex toys. Despite being new to the game, she eagerly accepts pleasure and becomes thoroughly wet. However, when it comes to riding cowboy-style during intercourse, she shows off her inner cougar by using strong hip movements that would make any man proud! Although she may be young, she definitely knows how to enjoy herself and embrace her naughty side.
