I was concerned about the future of my shy and withdrawn sister, so I started developing her nipples over the past 10 years in hopes of making her more active. 10 years ago, I started erecting her undeveloped nipples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 sister's nipples are as sensitive as the clitoris.
