Unfaithful

 

"Not within its strictest definition my Love." 

"Really. I would have thought that spending the night in a Black Stud's bed would make me just a little 'unfaithful', at least." 

"If you look up the true definition of the word, it states that - 'engaging in sexual relations with a person other than one's regular partner in contravention of a previous promise or understanding.' You have therefore not been unfaithful." 

"I'm sorry Dear, but I have been unfaithful to you with Deven - at least five times last night - and you are now a cuckold." 

"Oh I know I am a cuckold alright, but I have always understood that you will be seduced by Deven. In fact it was me who encouraged you to go on a date with him, wasn't it? And I have always known ....

.... exactly what the result of our understanding would be."
