As Ratchet's hand settles on his neck he straightens up and leans forward into the other man's space until their faces are almost touching, just giving them a moment to adjust to being so close with different intentions than usual. He can feel Ratchet's breath on his cheek, slow and even, far steadier than his own... he has to admit that he's nervous this won't go well, and that if it doesn't they won't be able to take a step back from it. He relies on Ratchet too much for that to happen.

As if reading his thoughts Ratchet takes that moment to reassure him, and York's mouth curves into a smile. "Good." He reaches up to mirror Ratchet, a hand on his neck tugging him forward to close the distance between them. The kiss is soft and careful, York testing the waters of this new thing.
