He moaned of his own accord and hurriedly stripped off his own shirt, giving skin to skin, giving Steve one more sensation to add to the experience. "Just right, Steve," he encouraged. "C'mon..."

There was no chance he was going to stop moving, not when everything felt so perfect. But he did move his mouth from Steve's over to the ear he'd neglected, this time setting his teeth down just enough to give the feeling of hard, slick teeth against delicate skin.
