You always bite my neck before you kiss me.

With us it's always lust over intimacy.

You're careful not to leave a mark, careful not to leave any proof.  

But I can feel it under my skin, it's your way of making sure I can't forget you, while making sure no one else will ever know about us.

It's like your always here, but standing just out of my reach.

One day I'll say no to you,

At least that's what I tell myself everytime you leave.
