Her teasing got the reaction she probably expected it would. Jacen just letting the sensations overtake him. Every nip, every bite driving him crazy and of course he knew Tahiri loved every second of it which only heightened what this was doing to him. Not to mention her own enjoyment radiated through the Force. That was something few others could understand.
And then of course all functional thoughts left his mind.
Every instinct he had was telling him to move, to grab her head, make this go at his pace, make the kriffing teasing stop, but of course that was part of it wasn't it? That was what she wanted and that was what he'd give her. The eventual payoff would of course be well worth it.
He didn't move, he didn't speak. Just reinforced the bond they shared through the Force.
