Hmmm...I'm not sure if these are exactly kinky but:
1. Did it with a girl in a pool while my buddies and their dates were swimming.
2. Did it on a blanket in the middle of a cul-du-sac (street corner) in the middle of the night to see if we could get away with it.
3. Did it in the outdoor hot tub at the Airport La Quinta in San Antonio in front of six floors of windows on two sides.
4. Did it in front of my buddies with a girl after knowing her for a grand total of less than fifteen minutes.
5. Did it on an airplane.
6. Did the two chicks thing, but I didn't really know either one so it wasn't that fun...fun, but not as fun as it could have been I think.
7. This doesn't count, but a girl once lost her composure and almost dropped a Cleveland Steamer on my head while we were into 69. That was a gross close call and freaked me out. She pulled up short thankfully, but we called her Miss Ash Wednesday henceforth anyway (get it fellow Catholics...stain on the forehead). eeew
That's all I can remember right now, but the list is long and seriously disfunctional.
