You lend a helping... tongue.

"Oh... hi... you two..." your mother pants, as she continues finger-fucking herself. "I was... gonna come in here to... tell you to... hurry up... but you were... so fucking hot... couldn't help myself..."

You put your glasses on, and your sister and you begin to dry off. Laura looks at you and says, "Hey, Sam, why don't you help her out while I dry my hair and get my makeup on?"

You look at your masturbating mother, then down at your flagging member, then back at your mother, and finally back to your sister. Your brain is still too foggy to put the pieces together. "Help her out?" you repeat. "I... uh... I can't do anything for a bit..."

Laura rolls her eyes. "Not with that, you idiot," she says. Then, by way of explanation, she sticks her tongue out at you, and wiggles it around a bit.

"Ohhhhh," you say, revelation hitting like a bolt of lightning.

"'Ohhhhh'," your sister repeats, teasingly. "God, you're so dense sometimes. Get down there and lick some pussy, bro."

Laura turns the hair dryer on and starts to blow-dry her hair as you kneel down in front of your mother's spread legs. A dense triangle of nearly-black pubic hair covers her thighs and outer labia. Gently, you use the fingers of both your hands to part her soft folds, revealing the pink wetness of her pussy inside. Tentatively, you stick out your tongue, and run it along the bottom of her silky puss, tasting her -- tasting any woman -- for the first time. You never really gave a thought to how it would be, and now that you're actually tasting it, you find it hard to put into words. It's slightly tangy, slightly salty, and definitely musky. It is the taste of a wolf's howl, of a sea breeze on the wind. It evokes some sort of visceral, primal instinct buried deep in your brain stem, something that dates back far, far before humanity was even walking upright.

And yet, despite hundreds of thousands of ingrained mammalian instinct supposedly pressing into you, you're not exactly sure what to do first. You run your tongue up and down her vertical, rose-colored opening a bit, flicking across her clit a few times, which causes her to jump slightly, but you don't really seem to be getting anywhere. Then something you read, somewhere on the Internet, bubbles up to the surface of your brain. Lick the alphabet. You remember it saying that the ever-changing patterns make sure the stimulation keeps changing, letting it build up more and more.

You figure it's worth a shot, and start out with A, moving from the bottom-left up to her sensitive clit, doing the same from the bottom-right up, and then crossing the center. Then B: one long stroke from top to bottom, and then two little bulges to the right. C, a long, leisurely counterclockwise curve. D, another top-to-bottom stroke, followed by the mirror-image of C. And so on. And you can tell it is absolutely working. Your mother squirms and moans, thrusting her hips up to meet your tongue. You keep going. You're at H now, then I, J, K... "Oh, oh god, yes, don't stop," she begs. Somewhere in the back of your mind you realize the hair dryer has stopped, but you can't let yourself get distracted. L, M, N...

"Oh, OH, OHHHHHH..." your mother cries, just as you hit that letter. "OH GOD!" You place your tongue squarely in the center, flicking it around gently, and you can feel her muscles contracting as she cums, a small amount of thick fluid coating your tongue. After she settles down, you pull back and look up at her face, raised up to the sky, eyes closed.

"Holy shit, Sam," you hear Laura say, and you turn to look at her. She somehow managed to concentrate well enough to put her makeup on during your little performance, and she stands there rubbing her own pussy as she observes the two of you. "What the fuck did you do?" Then, after a pause, "...Can you do that to me?"

Your mother is the one that replies to her, eyes still closed and neck still craned toward the ceiling. "Later, Laura," she says, dreamily. Then she stands up, somewhat shakily, turns to you, and kisses you gently on the forehead. "Thanks, sweetheart," she says, smiling, before opening the door and leaving the room.

The remainder of your morning is shockingly mundane. You and your sister dress for school, you in your boxers, jeans, polo shirt, and socks, and she in a yellow lace bra and panties, long white socks, and a black dress with colorful floral prints on it. Due to your "dalliances" you don't have time for breakfast, so you both grab granola bars to eat on the way to school. The only thing, in fact, that belies the strangeness of your new life is your nude mother giving each of you a full-throated, tongue-wrapping, passionate kiss goodbye when you head out the door.

As you walk with your sister, a sudden thought occurs to you. Last night, she mentioned that she'd be horrified if Jessica came home to find you in clothes. It could be a problem, you realize, if she talks about everything that's happened so far at school. A big problem.

"Hey Laura," you say, getting her attention. "Remember, all the nudity and sex we have at home is just between you, me, and Mom for now, right? Nobody else should know about it yet." You feel a little tap on your arm, the Manipulator acknowledging its activation.

She smiles and playfully punches you on the shoulder. "Well, duh, Sam," she replies. "I'm not gonna tell anybody about it until they're good and ready."

"Excellent," you reply, smiling. Phew, good thing I caught that. You and your sister part ways as she heads to her school, and you head off to the college... and to think, it isn't even 8:00am yet.
