Reversal

He entered the bedroom to find a young woman lying spread-eagle on the bed. Her curves were exaggerated to cartoonish proportions, thick thighs and hips bulged dramatically beneath a tiny waist, topped with massive breasts pointing towards the ceiling in defiance of gravity. She was clothed only in a black lace garterbelt, thigh-high stockings, and high-heeled ankle boots. Binding her to the bed, she wore heavy leather cuffs at her wrists and ankles, with a collar to match. The cuffs were attached by carabiners to ropes tied to the frame of the bed, with just enough slack to show that she must have attached them herself.

Moving closer, he could now see that that she stared upwards, unblinking, and that her skin was incredibly smooth, without blemishes or any fine hairs. It was obvious now that she wore a skinsuit, her curvaceous figure formed by layers of thick silicone beneath. The matching mask tucked under the collar fit seamlessly into the suit, and as he passed a hand across her gaze and she didn't respond to the movement at all. He guessed that she must be wearing some sort of blindfold underneath, perhaps even one of her heavy rubber hoods. He then noticed a small white card on the night stand, with a hand-written note stating simply:

  "Sir, please use me. -Gwen"

He kneeled on the bed and roughly slapped one of the massive breasts atop the prone form, causing the pair to jiggle for a long moment, but otherwise from the girl there was no reaction. This was no surprise, as Gwen's own modest breasts would be buried somewhere beneath the silicone H-cups in front of him. Unzipping his pants, he freed his rapidly-hardening cock and nestled into her impressive cleavage. Taking hold of a huge tit in each hand, he squeezed his member in between, slipping back and forth. As he picked up the pace, he grasped a large nipple between thumb and forefinger, tugging roughly and stretching them beyond any natural limits  - but still the doll remained silent.

He stopped and slipped further down to kneel between her legs, running his hands over her apparent body. He pushed a finger against the lips of the artificially-perfect pussy of the doll before him, yet no sound emerged from the masked face. He attempted to slip his finger inside, initially finding her hole to be surprisingly tight at the entrance, but was able to squeeze in thanks to some lube which she must have applied in advance. After a moment of exploration, he replaced the finger with his cock, taking his time to slowly enter the narrow confines of the textured sleeve buried deep inside of her. As he did so, her hips flexed unnaturally, rising up to meet him at an impossible angle. At the same time, he heard a muffled squeal - which sounded as if it was coming from the *back* of her head!

He was puzzled for a moment, and looked more closely at the woman before him. He now noticed that her legs and arms were held at an awkward angle, twisted just slightly past a comfortable pose. Suddenly he grinned. Leaning close to the side of her head he whispered, "you devious little slut, you have this suit on *backwards*, don't you?" The form on the bed twitched as if suppressing a giggle.

He realized now that he was actually thrusting into Gwen's tight ass, disguised by the thick silicone of the suit. Laying atop her, he reached a hand around to the back of the suit, squeezing hard where Gwen's own nipples must be pressed against the back of the suit. This time, she moaned in earnest, the hood suppressing the noise. He slid his hand down further, and through the layers of silicone he felt the gentle buzz of a hidden vibrator nestled against her clit. Slipping his hand between the large buttocks he found the anus of the suit, where he slid a digit it into her actual pussy, feeling his own knuckle against his shaft as he continued to thrust in and out of her. He grabbed a fistful of her hair, pressing against where her mouth must be located at the back of the doll's head.

He paused for a moment before withdrawing, prolonging the pleasure. Sitting up, he then slipped his fingers under the top edge of the collar, finding the seam of the mask.  He tugged the silicone upwards, revealing Gwen's true face beneath, a heavy gag strapped into her mouth.  She blinked at him with surprised eyes as he stood and untied her hands and feet. He smiled wickedly at her, and asked, "would it be cowgirl or reverse-cowgirl if you were on top?" She grunted in response to the terrible joke, and quickly straddled him, the suit's large fake buttocks crumpling awkwardly to bend backwards with her hips. He massaged her breasts through the suit's back for a few moments as she slipped his cock back into her real pussy. Their eyes locked in pure lust as she rode the length of his rod. He reached up and removed her gag, revealing it to also be penis-shaped inside. While she kissed him hungrily, he used the gag as a dildo to fill her ass, eliciting a groan from them both. He whispered, "This is just the best of both worlds! Why don't you be a good little slut and cum for me?"

Gwen accepted the order with enthusiasm. She quickened her pace, grinding her the hidden vibrator against both of them, until she exploded with pleasure only a few moments later.  He let her catch her breath for a brief moment, before remarking, "Good girl. Now, get on your hands and knees so I can finish." She complied again, the suit's limbs bent awkwardly backwards at a disturbing angle, her fake mons thrust upwards.  He removed the dildo from the suit's fake lips, and again entered her.  As he pounded his cock into her ass, she thrust her hips against him encouragingly. He took hold of the large breasts on her back, hanging on tightly as he suddenly erupted inside of her silicone-encased hole.

Laying back onto the bed, he sighed in pleasure. "The thing I love most about you is that you're always so full of surprises."  

She looked at him with amusement, "I'm guessing you enjoyed that? Not too strange for you?"

"Not at all." He grinned, "I guess you'll have to try harder."

Gwen looked down at him with a wicked smile, and arched an eyebrow.
