Should I run such things, this image would make for a great caption competition. I can imagine it as both a before or after shot. Obviously, with a look this disarming, the whipping itself will be a brutal one. But is this the before look of someone who has been gently coaxed into giving BDSM a try, and whose partner is about to discover that one should be careful what one wishes for? Or is the after look of someone who might have just got a little bit carried away, and is now wondering if the neighbors heard the screams?
I think it’s an After shot because I’ve seen it in exactly the circumstances you describe – a young beginner who has caught you across the balls and is partly alarmed partly excited and the way you’re convulsing. It’s “whoops was that too hard? …Never mind! I’ll crack on.”
Ha! Yeah, that moment “Is that a good doubled over in pain? Or a bad doubled over in pain?” is always a fun one. Partly because it’s sometimes hard to from both sides exactly what kind of reaction it is and what the follow-up should be :-).
