At first it does sound like its referencing fellatio, but I think it's actually about cleansing yourself emotionally.
'take a step off of that silver bird from your planet and you brought a little bit of that cold with you'
--> Sonny is encouraging the girl to open up to him but she's still in a previous bad state of mind, maybe being depressed or 'cold' because of a relationship with someone else
'ring me out like you would your bastarding father and youre so quick to stick to that scum hungry like a pirhana'
--> the girl won't trust Sonny or accept his help. She is staying in a relationship with someone who can only be described as 'scum' maybe because she feels desperate
'swallow a little of that sea. Now taste a little bit of that salt in me. Throw up a little of it on your knees, now doesn't that bring you back to the beginning before you poured your elements away. Now sing back to the bottom of it all'
--> The sea is something emense, cleansing and represents endless posibilities for her. Sonny wants her to taste freedom and hope again and wants her to see that he has those qualities in him. Throwing up the water is like spitting up the bad parts of herself and her past with it. It brings her 'back to the beginning', where she can start off fresh again.
