Worried about the future of my shy, withdrawn sister, I have spent the past 10 years developing her nipples in the hope of making her more active. 10 years ago I started teaching her pleasure by erecting her undeveloped nipples and playing with them. Seven years ago, I had repeated sexual experiences to promote nipple length growth. Three years ago, even after I had my first boyfriend, my nipples continued to develop. Now, my sisters nipples have become as sensitive as her clitoris, reaching the highest level of sensitivity. I have successfully trained her to be instantly sensitive. My sister grew up receiving nipple genius education and is now a nipple genius.
