Show your power

"Listen here, jokey Courtney", James said. "I want you to slide your index finger down from stomach to your pussy. No, under your clothes." added he as Courtney rubbed her crotch through her shorts.

"I don't want, please." said she while doing as she asked.

"Now, sis, lick that finger, suck it." said he, watching her face expression. "Tasty, huh?"

"Do you understand that you are mine now? That I have all the power here?" asked he.

"Err... yes, James, I am, you do." answered she with shaking voice.

"Do you know what that means? No?" smiled James, "It means that I don't need to use that power at all. Do you know why? Because you are going to be very kind, generous and loving happy sister from now. You are going to predict and fulfill all my wishes. And you are going to do it with a happy smile." ended he with a grin.

"You may **** me to do these things but I'm not going to submit to you." denied she. "I ..."

"Listen here, jokey Courtney", James interrupted her. "I want you to slide your index finger down your spine... do you have a clue what will happen next? Do you want me to continue?"

Courtney shut her mouth and became pale. "I understand. I'm going to be a very good sister."

"Good girl. By the way, I forbid you to take any action that will may free you from me, including releasing that fact. Aside that you may thing how to make use of yours and mine new relations."
