Aria gasped, in genuine surprise, as Kass wrenched her head back. She twisted her lips like a naughty girl as the standing bardess scolded her for her presumption. Her continued gasps became muffled as Kass trapped her head between the railing and the wet sex flush to her lips, and she moaned, "Mmmmff," quite muffled. This use of the railing hadn't even occurred to her, but as the sex ground against her pinned head, she realized just what it meant.<br/><br/>Aria nodded in assent, the bobbing causing her lips to rub against Kass. Then, like a girl with a sweet confection, she began to lick. While her hazel eyes gazed up at the commandeering face and bouncing breasts of the girl lording over her, Aria's tongue made long, lapping motions. It began each lick with a broad upward sweep, gradually curling and narrowing like a spade, whence the firmed-up tongue tip would press against the upper nub for a moment before twirling rapidly against it, like a fish leaping about out of water.<br/><br/>Gradually the tiefling's motions shifted from upward licks to a head-bobbing motion, that her tongue might thrust more deeply between the presented folds. Hard-fingernailed hands kneaded their way up the backs of Kass's thighs, clasped over her buttocks, and kneaded more firmly still. As instructed, her fingertips began to play in the cleft of the butt, right index finger circling around the tight puckered ring of muscle she found. Then, the first joint of the finger slipped in, penetrating the anus. Aria matched it to the bobbing of her head; her tongue and finger penetrated in sync, again and again, until her tongue buried so deep that she had to widen her mouth, and her other fingers had to bent away from the one that it might violate Kass's forbidden entrance up to the knuckle.
