Spairro bearing gifts

Spairro always travels a long way down the Interstate to visit the basement.  He often brings toys with him.  And I have the fun of applying them to his ass.  This time he brought floggers and whips.  One I really loved.  It decorated his ass so nicely.  One time before he brought straps that he had made for me.  Four straps in two widths and two thicknesses.  With very nice handles.  Those straps have been applied to the asses of many visitors to the basement.  Spairro of course got to feel them again this time.  And a number of my new toys.  In each case Spairro is able to explain the physical principal behind the functioning of each implement.  You know why a whip cracks?  Spairro will tell you.  You know why this strap hurts more than that one?  Spairro knows.  He's also then feels those straps to confirm his assertions.  Sometimes he's surprised.
