[JUR-169-UNCENSORED-LEAK] JUR-169 My fiance said he had no experience in the sex industry, but he had such amazing technique that I was completely suspicious of him and couldn't stop myself from masturbating. (Uncensored Leaked)

Fumino is the fiance of Yuu, the eldest son of a sake brewery that has been in business for 150 years. To marry into a distinguished family, she needs the approval of her strict father... Fumino, with her pure and angelic smile, is the ideal bride... or so she should think... But in fact, she has another face as Karen-chan, the legendary prostitute who has been ranked number one for three consecutive years. Her true identity must never be revealed. She appeals to her sense of chastity and teases him by not having sex until marriage... But for many years, the strongest Karen-chan (Fumino) has unconsciously unleashed her ``amazing technique''. Yuu begins to suspect Fumino. And her father also asks a detective to look into Fumino's background... What will happen?
