Accidental [F]lash leads to a bang [M]

My husband told me this story and it turned me on so I thought I would share it (with his permission)

Years ago I was at a party with friends, we were drinking and having a good time a mate of mine (Rai) brought his girlfriend along (Mel). We were all having a good time and Rai was drinking heavily and being loud. I’m not sure what happened next but Mel ended up falling over backwards over a couch, I noticed and went over to check on her, what I saw was her legs up in the air spread open with her skirt hiked up revealing she wasn’t wearing any panties and showing off her sweet trimmed pussy.
We both locked eyes the look on her face was one of “don’t tell anyone” and embarrassment to being turned on. We both stared hard at each other until a noise brought both of us back to reality. She straightened herself up, I asked if she was ok and helped her up. For the rest of the party we stole glances from each other, she was a red head and the carpets matched the drapes, towards the end of the party Rai was fully drunk and as I passed his house on my way home i offered to take him home, Mel came with us as I figured that she was going to crash at Rai’s place, they both hopped in the back of the car and I drove them home.
