After all these years, Daniel shouldn't still be able to do this. Jack
should be past the time of dry-mouthed lust, heart thudding painfully,
dick -- oh, let's not even think about how fast that can get in the
game when Daniel's moving toward him purposefully, eyes narrowed.
Should be. Isn't.
So when Daniel's hand reaches down, fingers curled anticipatorily, he's
got something to play with, something to tease, because Jack's ready.
And when Daniel kneels to play, getting Jack messy and slippery with
spit and, a really embarrassingly short time later, come, it's hard to
regret being a slow learner.
