Keep on sucking.
From Create Your Own Story
You ignore what she says, and keep on massaging her nipple with your tongue.
"Ah...Mm...Oh, oh! The feeling is growing stronger!" she moans.
You feel liquid in your mouth. It tastes like milk but better. You stop sucking and look down at her breast. There is white fluid sliding down her breasts and more coming out. You quickly get a bite of toast, chew it and swallow it, then lick the fluid clean off her breasts.
