Yuno, my wife's younger sister, who is much older than me, came to Tokyo for summer school and stayed at my house for two weeks. She has a gentle personality and is oblivious to men's erotic gaze, and she has a habit of unconsciously seducing them. Her innocent face and fair skin pierced my lolicon heart, and I decided to play with her nipples so that my wife wouldn't find out... I'll make her cum so that my wife (Yuno's older sister) doesn't rat me out. If I develop her nipples, she'll become a premature ejaculation type and we'll have a crazy sex life with my step-sister many times.
