Mark but this fle

Mark but this flea, and mark in this,
How little that which thou deny'st me is;
It sucked me first, and now sucks thee,
And in this flea our two bloods mingled be;
Thou know'st that this cannot be said
A sin, nor shame, nor loss of maidenhead;
Yet this enjoys before it woo,
And pampered swells with one blood made of two,
And this, alas, is more than we would do.
