As Edward watched them, he was a bit taken aback by the intensity of their orgasms.  This was wonderful! he thought.  They were both getting deeply caught up in this whole scene which would make it enormously pleasurable for all of them.  He continued to hold them for a few moments and then, reluctantly, he let them go and released the bindings to allow them to relax.<br/><br/>Now, of course, it was his turn.  Nothing aroused him more than having a squirming naked girl over his lap getting a spanking and with two of them, he could satisfy one of his fantasies.  There were actually two that he wanted to try and the wonderful question now was which to indulge in first.  Then he smiled as he thought of a way to indulge both.<br/><br/>"Alright you two.  On your knees."<br/><br/>He watched and smiled as both kneeled before him.  "Here's what we're going to do.  I am going to have a contest.  You are going to take turns sucking my cock.  Whoever can get me off first will win and I will spank the loser a bit later while the winner gets to indulge me again after I am ready.  But you have to take turns.  If you don't release me soon enough to give your sister a chance, you will lose unless I tell you not to release me in which case you can finish, knowing you won.  Plus, as an added bonus, the winner will get to spank the loser."
