Her feet had made it back to the ground only before he slapped her pussy. Then she jumped up again. Her breasts bouncing as she whimpered and tried to collect herself again. She was somewhat afraid of settling down again as she wasn't sure what to expect next from her brother. Still, she couldn't last long on her toes with how her arms were behind her back. She came to realize then just how important her arms were to balance.<br/><br/>She jumped for a third time, towards her brother when she heard the scream. She leaned against her brother and stared at the door, her body tense, she nuzzled him. For that moment, she didn't care that she'd stepped out of place. She wasn't accustom to hearing such noises. It frightened her. Her brother was the only one she would trust to protect her now, in any case.<br/><br/>Anna was about to ask what they should do when her brother spoke again. Her eyelashes fluttered and she blushed at the way he addressed her. It was strange to hear the words put together. The proposition he gave for her had her stepping back away from him. She looked to the floor ashamedly halfway through his speech before nodding. "As you wish." Was all she said then before approaching him with a gentle kiss.
