The sound a female makes while giving a blow job on a cock where it is hitting her in the back of her mouth/ throat area.
Candy gave me head last night but only sucked the first few inches. She refuses to bottom out on it and give me that "Quack in da Back ! )

If I was gay or Bi I know Loki would give me the "Quack in Da Back " because he loves sticking things in his mouth and down his throat..
