And Then, Even After They Finished That Go Round, Your Wife Called In To You To Laughingly "dare" You

And then, even after they finished that go round, your wife called in to you to laughingly "dare" you to go sleep in the guest room so the two of them could sleep together in the main bedroom. And it was even later, as you lay there alone in the bed in the guest room, that you realized they had planned for the game to end up like that all along -- and that this was definitely not the first time they'd had sex.
