"You," William answered, truthfully enough, and bit Gabe's jaw again. He followed the line of Gabe's arms, his hands skimming down until they reached the tangle of Gabe's robe around his wrists and paused to squeeze. That wasn't a bad idea, actually, Gabe struggling naked and bound beneath him, although there was something to be said for a competition of equals. And Gabe was perfectly-matched to him in every way; height, weight...slightly more muscle, but William enjoyed a challenge.
He pressed his mouth open over the pulse beating beneath Gabe's jawline, flattening his tongue against the throb of pumping blood. The skin was warm and tasted very, very faintly of faded salt, and William could practically smell the blood beneath the skin. He moaned appreciation and hunger against Gabe's skin, releasing his wrists to start yanking the rest of his clothes loose. There needed to be more skin bared. Immediately.
William whispered a disrobing spell and felt the magic surge through his fingertips, bright and wild. Gabe's shirt parted neatly down the front and William pushed it loose, impatient, tangling Gabe up again in the bunched fabric before it fell free to the floor. Then there was much, much more skin on display, and William took it all in, his palms shaping to the contours of Gabe's shoulders and the sleek planes of his torso. There was a perfect patch right below Gabe's collarbone, to the side of sternum. William followed his fingers with his mouth and bent down just enough to sink his teeth in, answering the call of Gabe's heartbeat.
