My brother was laughing and playing with my nipples and it was disgusting... I told him "You're not a girl, so stop touching me," but he saw me touching my nipples while masturbating, and that's how it all started. "You always make fun of me, but you're touching your nipples too!" And so began my days of nipple development. As he played with my nipples, they started to feel like clitorises, and I became strangely obsessed with them.
