Mary took a moment to assess her current situation. She was still wearing the pink bracelet which controlled the size of her dick and pussy on her left wrist, and the blue bracelet which controlled the size of her balls on her right. She looked around her. The pool of cum which she had produced from her pussy had spread across the floor, winding its way to one corner of the room. She was aroused again just by thinking of the volume of cum which she had just produced.
But still, she wanted more.
She remembered that she had promised herself that, given the opportunity, she would make her balls as big as possible so that she could cum as hard as she could. "Well," she thought, "I finally have the means to do just that."
Feeling her heart tremble in anticipation, Mary took a step back. She raised her right wrist and used the blue bracelet to make her balls grow again. She went through the first few steps quickly, growing her balls just large enough that they each filled one of her palms generously.
Her dick was as hard as a rock. However she fought the strong urge to masturbate. She wanted to see this through to the end.
She grew her balls again, feeling the increase in volume of the two orbs gently push her legs apart. This was as large as they had been when they were inside her. "Delicious," she thought as she licked her lips unconsciously.
