On the plus side, as far as Duma went he could just imply something instead of asking and if it was embarrassing he could always excuse it as a loss of translation. Bloody smart, it was. John'd take advantage of something like that all the time if he could. Mind, he preferred talking. A lot.
He snorted out something of a laugh at the gesture offered to him and really, John wasn't missing the request, not this time. "Already into that, huh?" He asked, cocky (because, well, he was John). But he did as was requested of him -- leaned forward again and tilted his head to the side in order to bite and suck a dark mark into skin that was pale enough to pick up some really interesting colors later. Assuming Duma allowed it.
