Juri is tall and has a cool appearance, giving off a strong and unapproachable vibe. Although she may not be suited to her current job, she doesn't fawn on men, and some customers say that she is straightforward and enjoys it, so she has gained a certain amount of popularity. One day, when she sat down at the table of a somewhat persistent dirty old man, they started arguing about whether his clit would get hard or not, and in the midst of a back-and-forth exchange of words, Juri couldn't help but say, "I especially won't get hard no matter what you do to a dirty old man like you!!" Since he said that much, they decided to try it out, and a game began in which Juri had to endure a vibrator placed on her crotch. As expected, Juri couldn't endure it, and instead she ejaculated into her panties. When the customer found out about her weakness and asked her to do something even more erotic, her erotic switch suddenly turned on, and she started to feel the excitement, bang, bang! But in reality, Juri is a real M!! Once she gets going, there's no stopping her, and she is forced into various positions one after another and thoroughly trained as a M using various toys.
