So aroused was he by his time that his tongue was moving at a maddeningly quick pace. He released her clit, only to ram his tongue all the way down into the narrow well of her shuddering pussy, licking more spicy juice off of her palpitating vaginal walls.
And as he did this, he let go of one of her cunt lips and slid his index finger in circles around her vulva, coating it with her oily juices. Once this was accomplished, the rest came easily. His finger suitably lubricated and his tongue doing a fantastic job of arousing every inch of her trembling snatch, he pushed her up a little off the edge of the bed so that he was able to wiggle and then insert his index finger right between the overhanging cheeks of her tight and rounded butt.
He didn't pull her nether globes apart but slid his probing finger up along her bum furrow until he was tickling the tender unblossomed folds and creases which swirled around her naked and hairless bottom-hole. Her response was all that he had hoped it would be.
Instead of shying away, she shoved her buns down so that he could feel the strong muscular contraction of her sphincter ring against the tip of his index finger. Thus, he palpitated her anus even as he ate out her cunt, slowly but surely loosening her muscular restraint until her perianus was totally loose and relaxed.
And when that was accomplished, he thought nothing of gently inserting his index finger right inside her tight and boyish ass. Ever so slowly, taking care not to hurt her with his fingernail he pushed forward and her anus began to expand, the folds loosening and opening under the insistent pistoning pressure of his trembling digit.
He kept at it, not stopping until he had managed to cram the entire length of his finger right up her tight dry poop. The spongy yet resilient walls of her virginal asshole twitched against his finger and he eased it back and forth, never all the way out, listening to her groans of joyous and delirious sexual bliss.
His tongue and finger made contact along the taut divisional membrane, that narrow septum which separated her anus from her vagina. He licked her cooze and finger-fucked her ass until his mouth was filled with more juice than he could swallow in one gulp. He'd held himself back until he had collected a goodly amount of her delicious juices and now, with three eager gulps, he swallowed the reservoir of musky fluid he had collected inside of his mouth.
Content to continue at this pace for as long as necessary, Drew was thus doubly pleased when a few minutes later his niece began to beg him to fuck her, or to at least allow her to return the favor by sucking on his huge and throbbing member.
"Oh please, please, do it, do it and I'll come. I'll make you come forever, I swear it, Drew," she grunted, shuddering more violently against his face, her legs kicking out and her thighs scissoring around his thick bull neck.
It was all he needed to hear.
He was not about to take his time any further, for any second and his body would have its way and he'd have wasted an abundant hot load of gismo Drew hadn't jerked off for the past week, saving up his come for the night when he and Amy would have it out together.
And that night had now arrived, their passions making each of them bum with an ungodly fire. So delirious was he as well as Amy by this time that he ripped his finger out of her asshole in a flash. And then he almost reluctantly removed his tongue from the wet surging cavern.
