This didn't happen to me, but I enjoyed being part of it.

It was prom night and my sister and I were both going. I had my tux on and was walking down the hall when my mom called me into my sisters room. She was going to help her get her dress on for the prom. She started giving me "the talk" while my sister stands there in an oversized t-shirt angry that she wants to get dressed. She finally tells mom that she is going to be late if she doesn't get dressed. I was tired of the talk and thought I would leave the room, but then the funniest thing happened.

My mother (who was kind of standing behind her)lifts up her shirt and starts to take it off. My sister is screaming and resisting with her hands which are now over her head. Because she had showered, she didn't have a bra or panties on and thus she was completly naked in front of me! I hadn't seen her naked since she grew her boobs, and it was so fun to stand there while she resisted mom pulling the shirt off her head as all her naked body parts giggled.

She finally let the shirt go and covered up her boobs and lower area with her hands, screaming for me to get out. Mom said that I had already seen her and she was still talking to me. My mom grabs a huge pair of panties to put on my sister and the two get in a fight over underwear. My sister wanted to wear a thong. She forgot I was there and stopped covering up, holding her thong in the air. Finally she put it on.

I felt sorry for her and left. I told all my friends and they like to joke about it with her.
