Dan catches some of this and while it's a talk for later, because he'd like Marcus to understand how truly extraordinary his presence in Dan's life is, he lets it pass them by. He does know what to do here, and even if it's been awhile, he remembers. Somehow, too, that this is still Marcus makes for a feeling of familiarity, even as Dan strokes along curves and lines he's never touched before.

He's already getting hard-- not because the female body excites him more, but because it's only minutes after this change and Marcus wants this from him.

With a groan, he rolls Marcus onto his back, mouth opening to deepen the kiss, to taste the new shape of a mouth he's so intimately familiar with, easing those amazingly, gorgeously long legs apart so he can rest between them. He moves his mouth to the slim column of Marcus's throat, tasting the pulse point, and without further hesitation, catches one pink, peaked nipple in his mouth.
