The target this time is Sayaka Otonashi, an 18-year-old beautiful idol who was a high school student until recently! We play with her with a water gun over her uniform until her nipples become visible, push her swimsuit into her crotch, and take this innocent girl who doesn't know what to do from left to right to the very limit of what she can wear. This time, we have a parade of "Isn't it Okay?" more than usual!
