10 Years Of Nipple Harassment By Me And My Younger Sister 10 Years After Developing Her Nipples To Make Her 13 Years Older Sister More Sensitive, She Began To Seek Nipple Pleasure On Her Own.

Worried about my shy, reclusive younger sister's future, I've been developing her nipples for the past 10 years to make her more active. 10 years ago, I started by making her undeveloped nipples erect and teasing them, teaching her pleasure. 7 years ago, I repeated sexual experiences to promote the growth of her developing nipples. 3 years ago, even after she got her first boyfriend, I continued the nipple development. And now, my sister's nipples have become as sensitive as a clitoris, achieving the highest sensitivity, and I've succeeded in raising her into a quick-orgasm, sensitive constitution. My sister, raised with elite nipple education, is now a genius at nipple orgasms.
