Hmmm... it looks like you were scratched maybe. If you were whipped or caned, I'd expect one would just go with the kink and not make a mystery of it. And if it were as obvious as you accidently scratching yourself while trying to spread your cheeks, then you wouldn't be making us guess either. .... netting, stockings, and webbing all leave a different pattern..... even a cat'o'nine leaves a different pattern... so... hmmm.. so its either going to be something mundane where you sat and rubbed or scratched yourself against it and it left the marks.. but that something ordinary isn't something your normally think to put your ass to... or.. its something so damn far fetched such as a random Goose flew in the open window and smacked your butt with its wings a few times while diving about in the middle of your photo shoot thus leaving such odd markings.. or maybe something with a Pineapple, a club soda, and that cute bartender.. you know the one. I could have just said that I don't have a clue, but where's the fun in that? at least all this BS was amusing. lol
Cuz the Midget was chillin in the conservatory smokin a bowl and having some noodles and you happened to stumble in. You were kindly invited to chill, noodle, and couch lock for a spell. And the couch had sequins which scratched your ass when you slid on over to accept in invitation. Those damn sequins will get you ever time. :P
