The submitter is Mr. Eishi Kurotori (pseudonym). [Below is from Mr. Kurotori] I portray a character named Airi. On the surface, she is a pure, cute, and cheerful young woman who works as a nursery school teacher at a facility run by her parents. She is well-liked by her close coworkers and the children she cares for, and she has a boyfriend approved by both sets of parents—appearing at first glance to be an ordinary girl. However, she has a hidden side as a hardcore masochist. Once her switch is flipped, she becomes wildly lustful, reacting with intense arousal and craving strong stimulation. In Scene 1, she masturbates by the window, aware of the outside view, heightening the sensation of exposure. Given her personality, public exhibitionism nearby is difficult, and without opportunities to travel, actual outdoor play remains challenging. In Scene 2, she experiences anal play for the first time—and as expected, she is highly sensitive anally. Her reaction surprised me, and I plan to continue developing her anally. In Scene 3, wearing an erotic bodystocking, she undergoes fist fucking and climaxes repeatedly. Once turned on, even being whipped makes her beg, "Hit me harder." She has even started orgasming just from being photographed straddling an extra-large dildo in a double peace sign pose. I am deeply moved by her extreme reactions and look forward to exposing more of her transformation. Stay tuned for my next submission.
