Original Sin 12

Original Sin 12 by AnonymousPseudonym

That's it, slave. Now kneel for me, and make sure your balls are resting in front of your bound legs.

Use your dominant hand to grab a wooden spoon, and use your non-dominant hand to ensure that your cock does not get in the way of you whacking your balls with the spoon. Do this 20 times and, most importantly, keep a very strict rhythm. If you are even a split second late with a whack, start again until you get it right - and make sure smacks are hard, slave.
