Merlin tightened his hold of her throat just a little. “You can come for me now,” he said, finally giving her permission to let it all go and come apart under his insistent fingers. He pressed rough kisses against the curve of her shoulder, and held her as closely up against him as he could.
The pressure on her throat suggested panic to an animal part of Luna’s brain, but this wasn’t then, wasn’t Colorado, this wasn’t a man who wanted her to die. She could speak a safe word here and Merlin would let her go.
(He would let her go, wouldn’t he?)
But the orgasm was building to its peak inside of her under Merlin’s unrelenting fingers and Luna started shaking her head as much as his grip would allow. She didn’t want to come, didn’t want to let it happen. She was holding back from the edge, but it was so difficult with the pleasure building and sinking in its claws. “I can’t, I- oh!, I can’t, I can’t.”
Merlin knew she didn’t like her throat held usually, but he’d thought to push her limits there. Apparently it was a little too much. He eased his hold of her, instead turning her head so he could kiss her. “You must,” he hissed against her mouth. “Luna, you are mine and I say, you must.”
