Merlyn's explanation of her actual abilities seemed to be enough for Sir Cador. Beyond this she'd just begun to tease his cock with her tongue when the man had a sudden shift in his own will. Her nature as a succubus made this man's desires her own, and she was starting to find his willfulness manifested in the strangest of ways. Most were selfish by their own natures, would repay favors just because they'd been given and made no offers if not coerced. So, imagine Merlyn's surprise when this man's newest desire manifested as one which involved her movement so he could give to her as well?
Her own work stopped for the moment though not without a teasing word or two, and a flick of her tongue along his shift. "Hm? How very hospitable, and chivalrous... Sir Cador~" she mused. A man like this who gave and took in equal portions was rare indeed, but she had no complaints to lodge as she shifted her person. She'd be above him with her knees on either side of his body, but her head would be aimed back towards her prize. At the same time, she'd end up presenting her sex to be tasted by the man below. Such a position was one of wonder, and one of infinite distraction, how much could be done while both people were experiencing the pleasure offered by another while trying to offer their own? She supposed if any managed to make this a properly enjoyable experience, Sir Cador would be the one. Besides, it was in her nature to take what was offered to her, even things such as this would always be accepted happily. A gentle twitch of her hips would leave her to return to work, her tongue flicking over the tip of him before her lips closed completely around his girth. Once this occurred she'd move her tongue against him as she found this angle ideal, for allowing the man shelter within the warm depths of her mouth.
