What is This I Find?

[JONAS:]
What is this I find
Under your behind?
Extra huge, and it's used
I wonder which two of us best of friends opened and used it?

[MARIA:]
Jonas, you know I waited (Oh, I threw away)
Waited 'til I couldn't take it (Your loving kindness)
I was alone, he called on the phone (I took you for granted)
And gave me the love you wouldn't (I'm all alone)

[JONAS:]
The only man I know (Think of the times we loved)
Who fits is our Dondó (Think of the child we have)
Extra-huge, (Love would come true)
And it's used (If I could undo)
I know which two of us (what you)
Best of friends opened and used it (made me do)
