It wasn't really MEANT to be public.
Boyfriend and I went on a picnic that he surpised me with to a very secluded clearing in the woods. After eating I was getting a bit bratty I guess, and he pulled out a leather paddle that he packed in the basket and began spanking me over his lap. I was really getting into it and he pulled down my shorts and panties and continued.
He was really letting me have it too. He was spanking quite hard but it was also very very erotic. I was so turned on and about to orgasm when he stopped. I got on my knees and started to attack him trying to get his shorts off for some fun.Then we both heard some noise. We turned and there at the edge of the clearing, was some guys and girls about our age, standing astride their bicycles and staring right at us. We had obviously not heard them before due to the quite a bit of noise we were making. We had also failed to notice the bike trail right next to the clearing.
I was embarrassed and mortified at the situation. There I was, on all fours, undoubtedly wet to my knees from arousal, with my very red bottom and everything else pointed right at them. Without stopping to think, I gave Mike a big shove back so I could yank up the blanket, spilling everything on the ground in the process and I wrapped it around my waist and ran for the car. It was not the first or last time we have been caught, but my most embarrassing.
