Farm Wife, Fence Rail Rider
I don’t know if her hands are tied behind her (and possibly down to the rail also) or if she’s just a kinky submissive farm wife who is doing precisely as she has been told. Either way, I think she’s about to get a tit whipping:
Elsewhere on Bondage Blog:
She looks like she is reacting to something that just happened.
Farm husband of course got excited by her pose, and got the idea she might like a little vibration. So he rapped the fence rail at the far end with an iron crowbar to send some pleasure her way.
But it did not turn out the way he expected. The sensation that she felt was like what happens if you grab a baseball bat too loosely with the hands when the bat makes contact with the baseball. The shock of impact makes a sharp sting.
