We were at a work-sponsored event at a hotel, and were seated in a lounge area with chairs arranged in groups of four. My wife sat chatting with my boss seated across from her and his wife next to her, and another wife on her opposite side. She had on a one piece dress with a jacket over top. The dress wasn't very long, and she didn't realize that how she was sitting, she was flashing my boss. People had thrown their coats, purses and bags on teh chair before my wife sat down, but she wanted to speak with my boss's wife. So, she sat on the very edge of the seat, one cheek of her butt hanging off the seat, her feet parted since her legs were turned at an angle to the chair.

The problem was, she thought she was being discreet by holding her hemline down, but since she was leaning on the arm of the chair to speak to his wife, and her heels were fairly high, her legs ended up speading. I was a few feet behind my boss talking to another co-worker and I could see her pink thong under her black skirt and see the thong plunging between her butt cheeks.

I tried to get her attention, but she ended up sitting that way for 20 minutes! I saw a couple of people peek, and my boss never moved throughout the conversation.
