Spock is, once more, thankful to be part Vulcan. It allows him the ability to multitask at a rate far better than anyone else would be capable. And in moments like this, it is a talent which is immeasurably useful. For instance, he is able to simultaneously monitor the damage the coarse rope is doing to Jim's wrist, the damage his own grip is doing to Jim's throat, and also enjoy thoroughly the look of pleasure on Jim's face at all of these ministrations.

It is...very good. And Jim is being absolutely perfect.

Spock smirks a little as he tightens his grip in time with Jim's struggles. At the gasp of his name, Spock's hand finally tightens the last little bit and restricts his windpipe all together. Mentally, he starts the clock while at the same time monitoring the pounding pulse he can feel under his fingertips. The skin contact, much like the first time, allows emotions to bleed through where Jim screams them at him. Right now, it's impossible to ignore the lust that clouds up the entire room. But it's pleasing to have it on a feedback loop, like this. Just like always.

"If you are able to talk, then you are clearly not restricted enough. Tell me, Jim. Can you speak, presently?"
