You prevent this

You don't wait for Solance to break free. The bonds are tough but she has a strong willpower. To prevent her from getting free you raise the corp and hit her ass three times very hard. She immediately looses focus and cries painfully.

“Seems like I need to show you who is in charge here,” you say and let the peek of the whip dance on top of her ass, “I can't allow you to question my dominance.”

“What the fuck do you want?” Solance asks angry “you want our food? Our Items? You will not find them, asshole.”

“Really?” you ask amused and grab the butt of the chubby sub, “and how about I take your pussy's first? Fucking you hard until you beg me? You will tell me the location of your stuff and you will give me your points. The only question is, who of you will be first?”
