Poison considers for a second. He gives Jack another smack, then sets the paddle down. He needs to reposition, in case Jack can't stay up right. He unties Jack's hands just long enough to move them to the front. Then he coaxes Jack to stretch out, moving until Poison can tie his hands to the headboard. It leaves him bent forward with enough slack that he could support himself on his elbows, but not so much that Jack could reach his own cock.

Better.

Poison picks up the paddle again, trying a heavier hit, just to see how Jack reacts. Even if Jack trusts him, he wants to be careful with finding the limit.
