Story Book Finish

When you eat a girl out and lick the tip of your thumb and flick through her pussy flaps like a book, then repeat this until she finishes, after she nuts you grab both sides of her vagina and slam both sides together like you would after you finish an excellent book.

Person 1: “Yo dude! How did it go with that girl last night?”

Person 2: “Terrible! She slapped me for giving her the Story Book Finish.”
