TPIN-069 Me And My Sister’s Nipple Harassment For 10 Years.I Wanted To Make My Sister Who Is 13 Years Older Than Me Sensitive, So 10 Years After Developing Nipples, I Started Asking For It Myself.Hina Iori

Worried about the future of my shy and withdrawn sister, I have been developing her nipples for the past 10 years in hopes of making her more active. 10 years ago, I started erecting her undeveloped nipples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, her younger sister’s nipples have become as sensitive as the clitoris and have reached the highest level of sensitivity, and we have succeeded in developing her into an instantly sensitive constitution. My sister, who grew up with a nipple genius education, is now a nipple genius.
