The pain jolts down your arms and legs. You hear your bones creaking and cracking. Your arms shorten but your hands lengthen, narrowing into the front legs of a dog. You watch the sharp claws grow out replacing your nails. Your fingers shorten and your fingertips thicken up and turn black leaving you with recognizable paw pads. Your thumb withers away until all that's left are dewclaws. Your legs shorten while your feet lengthen and you feel the same changes take over on your toes. You plant your new front paws on the ground as you sit there in a very dog-like stance waiting for the pain to end. It finally does. Apparently the curse is complete.
You sit there looking down at the front paws that had been your hands. If only you hadn't taken them for granted! You think back to earlier tonight when your only goal was to drive home in time to watch football. It seems so trivial now, staring at paws that can't grip a steering wheel or a TV remote or much of anything else for that matter. If only you had been more patient, more careful, and a little less short-sighted.
You are shocked to notice that your swollen knot is still there sticking out of your sheath. You hang your head in shame that the last memory you have of your human hands is jacking off a dog's penis. Desperate for some kind of distraction or comfort, you'd give anything to feel that warm calming feeling coursing through your body again. So you go for it. You sink your muzzle down into your crotch, let out your long tongue, and start licking down there like a dog can. Why fight it anymore? This is what your body is now, you might as well put it to use.
It's at least another 10 minutes before your erection shows any signs of subsiding. Your tail thumps against the floor while you clean your crotch. If you were a human, you'd be grinning deviously right now. You think back to all of those male enhancement commercials promising greater stamina. "Hehe, I bet they never pictured this," you think to yourself. Eventually you stop and watch the pink tip vanish back down inside your sheath.
You stand up on your four paws and take few steps forward. You turn and look back your clothes lying on the floor. You ears and tail droop at the memory of what the witch took from you. You look around and wonder where to go from here.
