The First Time You're Unfaithful

The first time you're unfaithful
Won't be the worst time you're unfaithful
It will probably just be a kiss
With a stranger when you're on the piss

And the next time, if you might fuck him
Or even worse, you might suck him
I know, I said I'd want to know
But that depends how far you go

How do you think we will adjust?
Now we've incorporated lust
And will you put my trust to test
If the shagging's not the best?
You said you know what I'm like

We were chatting with your sister
I was winding you up, you think I've missed her
She was fairly adamant
I'm nothing but a lying cunt

And the first time I'm unfaithful
Won't be the worst time I'm unfaithful
Once I've got a taste for it
I've everything to waste for it

So do you think I can adjust?
Now we've incorporated lust
Or will I put your trust to test
When my behavior's not its best?
You said you know what I'm like
