Girls who are sensitive are truly the best, aren't they? They react so intensely to even the slightest teasing, which makes it all the more exciting. Just imagining how such an ultra-sensitive girl could be pushed further, tormented relentlessly until she transforms into someone utterly slutty, is enough to make your heart race! Under the pretense of a physical sensitivity test, we subject her to all kinds of lewd pranks, reshaping her completely into an extremely responsive, horny girl. The relationship develops naturally, growing deeper and more intimate, strengthening the bond between them. This is a full-packed work filled with naughty teasing that gradually draws her out, step by step.
