I was concerned about the future of my shy and withdrawn sister, so I started developing her nipples over the past 10 years in hopes of making her more active. 10 years ago, I started erecting her undeveloped nipples and playing with them to teach her the pleasures. Seven years ago, I had repeated sexual experiences in order to encourage the length of my growing nipples. Three years ago, even after I got my first boyfriend, my nipple development continued. And now, my younger sister's nipples have become as sensitive as the clitoris and have reached the highest level of sensitivity, and I have succeeded in developing a constitution that is immediately sensitive to orgasm. My sister, who grew up with nipple genius education, is now a nipple genius.
