He watched her as she gradually got used to the steps and grinned a little when she ignored her slight blush and returned his comment. So that's how it was going to be, huh?

"In my experience, presents aren't always the most interesting things to unwrap. And by your earlier statement, I'm not getting them either way, so I might as well stay naughty." There was a slight undercurrent of something far less innocent than their playful banter in his voice and he stepped closer as she kept repeating the steps he'd shown her.

"Keep going," he instructed her and put his hand on her lower back, applying a bit of pressure. "Unlike the rumba, you arch your back in this one. If I was in front of you, you'd arch your midsection into me and keep your face turned away." As she followed his instructions, he gradually increased the pressure of his hand until she did an acceptable arch. "Good, now hold that and keep going." He removed his hand, but let it hover just behind her and just as he'd expected, she straightened her back a little after a few more steps. "Ah-ah, keep the arch," he tapped her back with his fingers. "More... Little more... I know it's a strain, but it'll pass. Eventually. Now keep it there. You don't need my hand to keep your posture, do you?"
