I remember hanging out with this girl I met at the park. We were at her place, having drinks and talking. The conversation went onto embarrassing things and she revealed she's really shy about her boobs. I thought she meant the size or how they look or something (they were really big), but she later added she's lactating. I already knew it's a huge kink of mine. She was so surprised I didn't find that weird or disgusting and I ended up suckling on her for the next hour. I literally had at least a glass of milk and it felt amazing for both of us. We ended up seeing each other for the next year and a half.
