Satisfied she's broken in her new toy, Zoe lets the pair off with a warning Winning Her Back chapter 18 by Hero_For_Hire

A low rumble of laughter escaped through Zoe's gritted teeth as Lydia pushed and pulled against her lips, desperate to free herself. The pressure relieved suddenly as Zoe opened her mouth, letting Lydia fall to the bed sheets below. She scurried across the bed as quickly as she could on all fours - her bitten arm barely able to hold her weight - and positioned herself before Zoe's toes, this time ready to work. Instead of presenting her soles for pampering, however, Zoe stood up from the bed.

Jack - no longer pinned under her foot - stood up and immediately ran to check on Lydia. Her bicep had a ring of bruising around it and blood blisters at the points where Zoe's teeth clamped the flesh flat. While Jack had never encountered one before, and therefore couldn't recognize it as such; he was looking at a crush injury. 

Zoe stood over them stone-faced, waiting for the theatrics to end. When Lydia's whimpering had died down and Jack's attempts at soothing her had stopped, she spoke. 

"I take it we all understand each other now?"

"Y-Yes... yes..." Lydia's response came first, and fast. Zoe looked to Jack who nodded and bowed. An acceptable response. 

"Good." Zoe nodded. "I'm going out. Jacki wants to do drinks." she speaks casually, and in a way that requires no response - like talking to a pet. "If I were you two, I'd find a way off this bed; if you're on it when I get back, you will be sleeping with me." She paused for a response, but Jack and Lydia remained still with their heads bowed in obedient silence. Zoe couldn't help but feel a little proud of herself for training Lydia so quickly.
