Just Nicole, my girlfriend at the time. She quickly (and shyly) flashed me back. If you mean a stranger, then no.
Never even thought about it
i accidentally did it once on a public sidewalk. I was wearing a short dress and 6” heels. I tripped and fell. There was a girl about my age walking toward me. She knelt down to help me. I realized my dress had slid up and she could she my pussy when she put a hand on my leg just below it. After asking if I was ok, she helped me up then brushed off the back of my dress, almost like she was spanking me. I told her I might need help getting back to my apartment so she walked with me and we spent the afternoon together.
Funny story...
I went on a Girls Cruise, there were 5 of us, 3 in our balcony cabin and 2 in the inside cabin across the hall. We were expecting the ladies across the hall to come over any time, to have a cocktail with us as we sailed away. We left the door ajar for them to enter. On a wild whim, my sister laughingly suggested that we should be naked on the balcony when they arrived.
To my surprise, our other roommate jumped quickly on the bandwagon and before we knew it, we were sipping champagne naked out on the balcony as it passed through the harbor. We'd pulled the curtain to the balcony, so that when the ladies arrived, it would be a surprise as they passed through the darkened cabin and opened the curtain to access the balcony where they could hear us laughing.
Inside Cabin Lady #1 arrived first to discover the Bare Balcony Babes leaning casually against the railing facing her, toasting her,. #1 shrieked loudly with surprise and then broke out into howling laughter, causing Inside Cabin Lady #2 to rush into the cabin asking What the Hell??? The curtain was still obscuring the view and all #2 could see was #1 falling over laughing and pointing to the balcony door with tears streaming down her face. When #2 pulled back the curtain and beheld the 3 Nude Sirens splashing champagne all over ourselves in our own fits of hysteria, #2 yelped and turned bright red, breaking out in her own fits of laughter.
The 3 naked ladies then chorused, Let the Fun Begin! Yeah, we made a Vacation Memory on that trip, that's for sure!
