[TPIN-069] My Sister's 10 Years of Nipple Harassment - A Younger Sister Who Became Sensitive After 10 Years of Breast Development Begged Me to Make Her Nipples Hard and Orgasm
Over the past decade, I have been carefully developing my shy and reclusive sister's future by helping her become more active. Ten years ago, I started teaching her about pleasure by stimulating her undeveloped nipples until they became erect. Seven years later, to further enhance her breast development, we engaged in sexual experiences together. Three years after that, when she finally found her first boyfriend, I continued working on her nipple development. Now, thanks to my efforts, my sister has reached peak sensitivity and has developed into a prodigy at achieving orgasms through nipple play. She is now an expert in making her nipples erupt with intense pleasure.
