Recently, Riku-chan's chest has grown rapidly during her growth spurt. A few years ago, she was just a struggling gravure idol, but her beaming smile is incredibly cute. Now that exams are over, it's time for some H part-time work. First, have fun SEX with an uncle. The second round, a big dick bangs against the uterus, driving one crazy with sensations never experienced before. Enjoy watching the smiling face of this developing giant-breasted girl turn into one of agony.
