“Go on then,” Merlin said, like he was giving her a treat. He didn’t think he’d met anyone else in recent memory who enjoyed a cock like Luna did. There was that one girl Maggie in... 1906? but that was far too long ago. He did enjoy watching her. She was so passionate about her work.
Luna liked the encouragement, and she focused all her attention on what was in front of her then, taking him more deeply into her mouth as she continued with her hand at the base. It wasn’t difficult to get into it, to feel the aching between her legs as she listened to his sounds of pleasure and thought about getting fucked by him later. She enjoyed taking him deep and holding him there, her tongue working against the bottom of his cock as her eyes teared up slightly. Thank the gods for the invention of waterproof mascara and eyeliner. (Well, unless the situation called for it. There was something to be said about the sexiness of smeared makeup.)
Merlin had to put one hand up against the bookshelf to steady himself as Luna swallowed him down, lips parted in arousal. By all the gods, she was good. Looking down at her, he placed a hand on her head, stroking her hair, gently holding her in place as he rolled his hips forward and back. He didn't want to cause discomfort, but fucking her mouth was blessedly good.
"You're going to have to stop if you want me to fuck you," he groaned, feeling a shiver down his spine.
Luna’s hum against him was one of amusement and she drew back, tilting her head to look up at him. “It’s your night,” she reminded him, and the expression on her face was hungry and impish. “Where do you wanna come?” As she spoke, her hand remained on his dick, although its movements were almost imperceptible now. Almost.
"Oh, but I very much enjoy pleasing you," he replied, his breath coming deep. He licked his lips quickly. "Open your mouth. I want to see you take it." And then they could have supper, and he would take her up to his bed and fuck her thoroughly. Yes, he liked the idea of that.
