Let It Dribble Down Like Syrup
"Now, Abi, can you do me a favour and dribble your spit all over Daddy's finger by dropping it at the top and letting it slide down until my entire finger is covered in your sweet saliva?" Even though he looked like he was only suggesting it, he had already brought his hand with his middle finger up right on top of her breasts, like he was waiting for his finger to be lubricated. And all she had to do was bend down, open her lips, and let her saliva flow out.
She would've hesitated at first, as she had never spat out anything before other than when she brushed her teeth, not to mention on anyone else. But because her mouth was already full of her fluids that were waiting to be emptied, she didn't think about it too much and decided to do what her son said while her ears slowly turned red.
