The woman behind me at a water park ride lost her top [I Got Caught Naked]

I was 12 at the time and she was about 20 or 21.

I fetched her top for her. She said thank you and then asked me to stand in front of her while she put on her top so other people couldn’t see her.

She took her arms off her boobs and put on her top. My face became redder than hers as I saw my first pair of boobs ever. She giggled at me and then left the pool and I never saw her again.
