This lovely bonfire spanking photo comes via Nympho Ninjas, where Trouble writes that it is:
Part two from our series on the beach from Valentines Day. I was a very lucky girl to have Ninja keeping the best bonfire alive all night and even luckier to get to feel the heat from his hand in front of the heat of the flames. I loved how this one turned out as you can see the movement of his hand spanking me from the long exposure. I couldn’t have asked for a more perfect night.
