Amethyst took a position in the sand of the beach, making a gesture that Peridot took to mean that she should take up a position across from her in the sand, some 20 'feet" away.
"I'll start," Amethyst said, hips already on their way to wiggling. "Remember that we're trying to like synch up to each other, so aim for that!"
Amethyst started up her dance while Peridot watched, trying to see the rhythm behind her steps. After several seconds and an impatient gesture from Amethyst, Peridot started to dance herself. It was jerky, trying to copy the basic steps from Amethyst's dance. There was a beat to her steps, so long as Peridot tried to punctuate her movements along with that beat, she could feel a wavering tension snap into place across the sand between them.
"Yeah! Feel that?" Amethyst was slightly out of breath from her own efforts, punctuating her words with flourishes Peridot was feeling at a loss to keep up with. "Aim for that!"
Peridot slitted her eyes, trying to focus more on the nebulous thing between them. It was like trying to navigate the distance from the thinking room to the front door in the dark, feeling for it with senses she wasn't even sure she was equipped with. As the seconds passed, Peridot could feel her body sliding into the groove that the tension between them was calling her too, anticipating the rhythm instead of reacting to it. The line between them became paradoxically more convoluted as Peridot felt it drawing herself and Amethyst closer. There were accent rhythms, flourishes that she felt as much as saw. She could feel how much Amethyst was enjoying dancing just for the sake of dancing. It was infectious. Peridot let herself fall into all of it, the rhythm, the joy, the flourishes of a music that she couldn't quite hear, but could feel in the very matrix of her gem.
Amethyst was dancing only inches from her now, the heat of her metabolism enough to feel. Her half-lidded eyes caught Peridot's and there were so many things she could almost feel in that gaze, words she didn't know trying to make themselves in her mind. The power between them was palpable now, a living thing all it's own trying to come into being. Amethyst spared her a wink, full of something the link between them translated and Peridot, full of the spirit of the thing between them, laughed and danced away, prolonging this just a moment more. Amethyst stuttered a step, the word 'tease' crawling into Peridot's mind, though Peridot had never used the word with the emphasis that was being applied to it. It made her bold. As Amethyst followed her across the soft sand, Peridot had no illusions of holding out for long, but she found she did like the feeling of leading the last few steps, of being pursued. Peridot maintained the distance between them for a few moments longer, finally answering Amethyst's flourishes with little flourishes of her own. Amethyst finally closed the distance, swirling in in a way that took advantage of her particular center of mass and grace while Peridot gave in to the spirit trying to come to life between them and reached out towards her.
And then there was someone new twirling across the beach.
