Ben comes in naked and is told to position himself with his feet on the back of the sofa and his hands on the floor. This means as he tries to stay in position his ass muscles tighten and the swat hurt that bit extra. Using the ping pong bat for maximum coverage it seems that this is true as Ben jerks his head up and down at each impact, watch closely and you can see his buns quivering as the position takes its toll. The random pattern of swats keeps him in a state of tension as well. An unusual position but one that should be used again.
