dressed in your mom's lingerie, masturbating as she fantasized aloud about you

Your eyes went wide and your jaw just about hit the floor as you saw her, sprawled out on her back atop the bed, dressed in some sort of white mesh teddy with matching stockings, garters and long satin gloves. Topped off with a pair of strappy white platform heels. You'd never seen your mother's body dressed in such a manner before - the outfit looking a lot like something she had perhaps worn on her wedding night - the tight, stretchy material clinging to every curve, almost like a second second skin.

What you'd also never seen before was what she was currently doing while wearing it. Her head held back, eyes closed and beautiful shoulder length blond hair splayed out on the pillow behind . Her back was arched, and her large, jutting chest heaving dramatically outwards - practically bursting its was out of the cups of the teddy. Most importantly of all though, and the thing that was making your entire face blush red as you stood there, frozen outside in the hallway, was the gloved hand between her parted legs, furiously pumping in and out of her exposed vagina. Three satin covered fingers having smuggled themselves inside her prominent pink folds, masturbating her to a stupor!

"MMMmmm God... That's it, Timmy baby. That's it. ...Give it to mommy! Mommy loves your cock SOOOO MUCH!"

Oh my God... She was masturbating. She was masturbating while fantasizing about you. She was masturbating your mother's body while fantasizing about you!

It was... it was perverse! Yet for some reason you couldn't look away. You couldn't do much of anything other than stand there staring, in complete and utter shock. You shouldn't be seeing this. It was just so wrong, and pretty much the very thing you had run away from earlier. The thought of your own mother in any kind of sexual situation being too twisted for words!

And yet, here she now was (or her body at least), writhing around on her bed, panting and moaning ecstatically as her fingers plunged over and over again into her wanting sex, while the other hand squeezed and groped at a large fleshy mass that was desperately trying to escape the overstretched lingerie that contained it.

"OHHHhhh yes! ...Yes, baby! ...Plunge that big cock back inside mommy!" she cried, her voice breathy and oozing with a pleasure you'd certainly never heard your mother make. "...Put it back where it belongs!"

You'd also never heard her say anything like this before either. It sounding so incredibly filthy and perverted, and not something you ever thought you'd actually hear her say.

As loath as you were to admit it though, you were transfixed. Shocked... yes, but transfixed none the less. You'd never seen anything like this before other than on your computer, and especially not less that ten feet away from where you now stood. Her dress, her enthusiastic performance, her blissful squeals, not to mention the words that were coming out of her mouth being a lot more reminiscent of Amber Knights than anything else you'd experienced so far. This performance really did look like it belonged in a porno movie - not your parents bedroom!

Almost against your will, you could feel your body begin to respond to this display. Your heart beating faster in your chest as your penis gradually began to rise. You just couldn't help yourself. Even though it was your mom... it was her body - she was dressed up in sexy lingerie, jerking herself off like some wanton slut in front of you. It was without a doubt the hottest, kinkiest, most hard on inducing thing you had ever seen! You cock really couldn't ascend any faster in your pants if it tried.

Fuck me... you groaned, unable to contain yourself any longer as your hand then found its way into said pants.

That was your mother's vagina Stephanie was ramming her fingers into. It being mostly blocked by her hand, but still... It was the first real life vagina you'd ever seen, and it was also the very same one you yourself had come from. It should have been deeply disturbing. But it wasn't! Everything about it was as hot as hell. Her pussy. Her huge breasts. The sound of her voice screaming loudly about how hard she wanted you to fuck her... I mean, how the hell were you meant to resist that? You were only human after all!

Wrapping your own fingers around your pole and leaning your body up against the door frame, you began to jerk off in time with Stephanie. You felt incredibly guilty and ashamed of what you were doing, but you were just too damn aroused to stop. Especially after, moaning loudly, you watched as she then inserted another finger into her drooling slit - her heavily made up face contorting as the lips of her vagina stretched wider to accommodate the extra digit. Causing juices to spurt out all over her stocking clad thigh, and for her to cry, "That's it baby!...Stick it all in Momma's hungry little cunt!"

Then, with her fingers still busy between her legs, she sat up a little and pulled at the straps of the teddy, freeing one of her exceptionally large breasts. "Mmm yeah... Play with my tits for me baby... Play with mommy's big ass titties!"

In all the years you'd known your mother, you'd never imagined she had boobs like that. The large spherical mass of doughy flesh looking to be about twice the size of her hand, hanging low towards her waist (which was comparatively slim for a woman of 40) with just the right amount of natural sag. Her nipple was also immense. The dark, crinkled areola being about the width of a teacup, and the large brown nipple protruding from it about as thick as finger. These were fucking breasts! Not the perfectly symmetrical, fake plastic ones you'd seen on TV, or even the gigantic basketball sized orbs Amber Knights possessed. These were a pair of all natural, mother nature's finest, mature breasts. Really, really, really big ones at that. Stephanie had been right - your mother was stacked!

How could this be your mom though? How could she be this damn hot? you thought as your pumping grew ever more vigorous. Watching then as she then began to play with her breast - pulling and teasing at the big fat nipple and giving off a squeal.

"Suck it ,Tim! Suck my fucking tits! ...Just like... just like when you were a baby!" she commanded, hoisting the huge jug up towards her face and in one fell swoop, engulfing the swollen nub and as much breast flesh as she could manage.

"MMMMmmm!" The muffled sound she made with a mouth full of breast was almost as arousing as the sight of your her powerfully sucking lips, hungrily mauling away at it. As if it was the most succulent and juicy thing in the world.

You'd always fantasized about seeing a woman do this in real life. There being something about suckling on their own tits that was so damn exciting to watch. With Allison it was of course out of the question (even if you did somehow work up the courage to ask her), her boobs being just too damn small - barely more than an B cup. Your mom's however were ginormous. Surely pushing into the J or even K range, and actually getting the hard, puckered nipple up towards her mouth had been an absolute breeze. She didn't even really have to bend her neck!

As well as this though, you also had the added kink factor of that being the very breast you had fed from as a child, and the sight of this kind, loving, nurturing woman - who in the past, you'd never even imagined took her clothes off - doing something so overtly sexual with her own body was a turn on like no other. You really did feel like your now rock hard penis was about to explode from over excitement, as she pulled and stretched at the taffy like nipple with gusto. All the while still jamming four fingers into her soaking wet and increasingly overstretched love hole. There really was no words to describe it.

"Uuuhhh - uhhh fuck! ... Nearly there!" she moaned, releasing her now drool covered tit and letting it slap loudly against her chest, her body writhing even more now as her breath grew heavier and her hand grew faster. The loud squishing and squelching sounds of her vagina echoing around the room as she reached a crescendo. "Nearly fucking there baby!... Momma's gonna... Momma's gonna..."

What happened next you certainly hadn't been prepared for. As pulling her fingers free, screaming in ecstasy and spasming rather violently on the bed, a powerful jet of clear, watery liquid suddenly burst forth from her vagina, arching up about four feet in the air and splashing down on the carpet below.

"Uhhuhh- shi-shit!" you grunted, ejaculating right there in your jeans as your mother continued to squirt, Stephanie making the most incredible noises while she did. Unfortunately though, the unexpectedness of your orgasm, added to your current position by the door, caused your shoulder to accidentally jerk forward, banging into it with a loud thud.

...Fuck!
