Delta-in-York's eye flares a bright green, the sudden surge of stimulation crackling through him like nothing he's ever experienced before-

Backed with an undercurrent of pure protective fondness he cannot quite articulate. Pride? Something of the sort. He swallows and slides a hand down to continue combing his fingers through Locus' hair, thighs tipping apart obligingly. As an AI he has no shame about the body he wears, York is remarkably well put together in his humble opinion, adequately attractive and, apparently, sensitive.

Or perhaps that is simply him. Breathing settles in slow and deep, York slipping forward enough to keep D from choking, to let him enjoy how it feels- "He is-"

Delta starts, hitches his hips slightly to rock experimentally down against Locus' fingers. "Overwhelmed with fond appreciation for you right now."

The care he is taking. The consideration. "I find it difficult to differentiate from my own sentiments."
