Love This Betrayal

I've been neglecting her a bit lately, I haven't been that nice
I thought I'd get some flowers and take her out for drinks
Then have a nice dinner topped off with 40 winks
But something wasn't right when I opened my front door
There we're clothes scattered everywhere and nickers on the floor
I rushed upstairs furious, I'd gotten into such a state
And when I kicked the door in there she was 'with her mate'
Now cheating is cheating, yes, yes I know it's wrong
But my wife was dressed in leather and her mate only a thong
They saw me in the doorway, then beckoned me inside
Well if this is betrayal I thought, I've come along for the ride.....
