He was her Lord and Master, she was his Apprentice... and partner. Not his equal, not in terms of the Force, he had considerably more power and control than she did. But when talking about them, their relationship, that was more of an even playing field.
So as much as the thought of him simply taking her, knowing as she did just how satisfied he could make her, Tahiri simply smirked at him. "Maybe next time," she eventually replied, satisfied that he was staying just where he was. "This time, I'm the one in control, and we're going to do what I want." Because she could feel it, his consent, his confidence in her. And he was right, she would be able to sense the moment that changed, if indeed it ever did.
She stretched up, pulling the tank top she was wearing up and over her head, shaking her still damp hair loose and letting droplets of water leave wet trails over her skin. Tugging his shirt off the rest of the way did mean making Jacen lean forward a moment, but the second the garment was thrown to one side, Tahiri instantly had his hands pinned back down again. This time it was bare skin pressed against bare skin, her soft curves against his muscled torso.
With more of his body exposed, Tahiri went back to kissing him, making her way over his shoulders and down his chest, alternating between hot kisses, light bites of teeth and flicking licks of her tongue. Her body slid down his, lithe and flexible, pressing against his as she moved her way down. This time when she looked up, there was no question in her gaze, just her desire to see his reactions to what she was doing, using all her senses, both physical and with the Force, to help her sense him.
Just because she was the one in control, because all her movements were her choices, didn't mean she didn't want to know exactly how he was feeling, to get that thrill of knowing that he was getting aroused by her and her actions.
