He couldn't stop the grin from spreading across his lips, even as his tongue worked at flicking quickly at her hot sex. Teasingly working upwards and then downwards, agile muscle showing surprising dexterity as he withdrew only momentarily..allowing the flat of his tongue to tease much lower on her outer folds. He worked his way along her again, only briefly flicking the tip of his tongue against her sensitive skin. He loved to hear her moans, he realized..not just in the same way that it is encouraging to a man..but he found himself growing more and more ravenous for her as she did so.
It showed as he found the hard bud of her clitoris, lips sealing around it as he sucked firmly..tongue lashing it with surprising ferocity. Hands still gripping her thighs firmly, allowing her no room to move as he expertly worked his mouth around her sex. His tongue once more delved into her hot core, working circles and lashing alternately against her slick skin there. He pulled her hips a little further off the desk as he sucked at her sex, pausing only briefly to sink his teeth into the nearby flesh of her thigh in counterpoint to his actions between them.
