I was old enough to stay home, but not old enough to watch my kid sister and brother. So my parents got a friend of the family to watch us while they went away for the weekend. We spent Saturday swimming in the nearby lake. She looked so good in her two piece suit. She was about four years older than I and she was developed!
Anyway, after the kids went to sleep, she went down stairs to shower. I snuck downstairs too hopeing to see something. Well the basement was unfinished and it was a huge one room with a small shower stall in the corner. The rest of the basement was the washing machine, dryer and a table for clothes. So I was waiting, with the excuse that I was looking for clothes if asked. I heard the shower stop and I held my breath, with a pounding chest. The door opened and she walked out naked with a towel over her head. She was wrapping her hair up and didn't see me. I just stared at her and didnt say anything. Then she saw me and screamed. It was hot. She jumped and her whole body jiggled. I still remember it.
She grabbed her towel and pulled it over her front. I said I was looking for clothes, and I pulled out some underwear and a shirt. She just looked terrified. She walked by me and got her stuff and quickly dressed under her towel. She begged me not to tell my parents.
