While drinking at home with a senior from my college club, I met his younger sister, the nympho-bitch Mizuki, and she attacked me... It was a storm-like day where I was forced into grind cowgirl and cunnilingus, and we just kept fucking until morning. Pussy-to-Cunnilingus (PtoC) is a continuous sequence of grind cowgirl followed by face-sitting! A new genre of repeating grinding and eating out!! Produced and Copyright by K.M. Produce Co., Ltd.
