"So, slave, what is your name?"  
The queen glared imperiously down at the kneeling figure she addressed, her blue-and-black-latex-clad torso rocking gently back and forth on the huge, cloth-covered shape beneath her waist.  
"Umm-- N-Natalie, ma'am," the girl before her stammered in reply, hardly daring to make eye contact with the queen. The queen arched a disapproving eyebrow and leaned forward slightly. This shifting of her weight caused her to swing forward on her massive lower body and be brought barely a few inches from Natalie's terrified face. From under the cloth came a rubbery creaking, like that of a balloon.  
"You will address me as "your majesty" if you don't mind, Natalie," the royal sternly reproved. Up this close, Natalie could see every glimmer of light on the tall lotus-like petals of the queen's collar, and smell the mixed scents of her delicate perfume and her latex garb.  
"Y-yes, your majesty... sorry, your majesty..."  
The queen's expression softened somewhat, and she smiled slightly. "Much better. Suitably respectful for a good obedient slave." Satisfied, the queen leant back and rolled on her bloated bulb-like body into an upright position. "You may stand up now, Natalie, and let me have a look  at you."  
As Natalie got to her feet, she realised she was fiddling nervously with her fingers and made a conscious effort to put her hands to her sides. She stood blushing to attention before the queen, her nude body on display for the monarch. The queen studied her intently, putting a gloved finger to her mouth in thought. Presently she nodded to herself.  
"Yes, you should do nicely..." she said partly to herself.  
"Er, do nicely for what, your majesty? I-if I may ask..."  
"You may ask. I intend to have you assist me with putting the finishing touches to my gown."  
"Oh. Well, I'm not much good at sewing, your majesty..."  
The queen chuckled softly. "No no, you misunderstand me. Here, remove this cloth and you'll see..."  
Hesitantly, Natalie stepped forward and swept away the cloth covering the queen's gown. Underneath was a vast mass of gleaming blue rubber, a tremendous inflated skirt with huge bulging pleats and a rounded base on which the queen continually bobbed back and forth. The join between the queen's slender waist and the wide bulb was rimmed by overlapping latex petals, lending rather a floral motif to the ensemble. But none of this was what most drew Natalie's attention.  
Crowning each of the huge chambers comprising the bulk of the gown, framed in a flower-like rosette, was a latex-coated human face. The black rubber stretched over them was thin enough to frame and define the basic features of the face, but just thick enough to obliterate more subtle and distinguishing features beneath its smooth polished surface, rendering each face plain and indistinguishable from its counterparts around the gown, bordering on androgynous. The rubber-coated breasts beneath the sealed faces, however, offered a definite clue as to the gender of their imprisoned owners, whether natural or imposed by the dress.  
Natalie stared aghast at the nearest face, her hands covering her mouth in shock. She leant closer to it, her wide eyes looking over it in amazement. The black latex smoothly delineated its basic contours - two eyes wide open like Natalie's, a small cute nose, and a shallow concave pit where the latex was stretched over a mouth gaping in a silent scream.  
"Are... are those... people?!" Natalie gasped in horror.  
The queen smiled. "Oh yes, they are," she answered, reaching her hand down to lovingly caress the forehead of the face closest to Natalie, "slaves just like you, hand-picked by me for their beauty, to decorate my lovely gown."  
Under the queen's gentle touch, the face gave a long moan, muffled by the tight latex mask. Whether the moan was one of distress or pleasure Natalie couldn't say, but either way she took a few steps back.  
"Oh my god..."  
"And you, Natalie, are to become the latest living jewel of my fine slave-gown!" the queen continued, smiling magnaninmously at the terrified girl. "Isn't that nice?"  
Natalie shook her head. "I... I-I can't--"  
"But you will. You shall most assuredly take your place in my finery, whether by choice or by force." The queen's voice took on a harsh edge with this statement, infusing her words with her royal authority and making them seem less like an order and more like a simple fact.  
The balance of Natalie's emotion bounced back and forth briefly between dread at whatever fate awaited her in the slave-gown, and fear at the queen's fury should she attempt to deny her. In the end, the latter threat won out, and she nervously approached the broad bulging dress once more. She walked around it until she came upon a plain bulge, with neither breasts nor trapped face upon it. She reached a shaking hand out to its polished surface and touched it gingerly. Almost as soon as she did, the blue surface of the gown opened up before her like a receding tide, revealing an inner mass of black latex. The black material surged out at her, rubber pseudopods ensnaring her before she could do anything more than scream. She struggled to wrestle herself free of the gown's grip, but the latex was too pliable to break and too firm to escape.  
The black mass drew the writhing girl inexorably into itself, spreading smoothly and viscously over her body. It drew her limbs gently but firmlybehind her back, letting them sink into the bulk of the rubber. As the latex closed over them, Natalie found her arms and legs immobilised, rubber pressing snug and skintight against every square inch of naked skin, with barely any give whatsoever. The latex didn't stop there, continuing to coat Natalie in a restraining black layer. It sealed over her breasts, cupping and supporting them ready to be displayed on the gown's surface.  
Just as the black latex had closed over her, the gown's outermost layer of blue latex began to close over the black. As it did so, the black latex made on last push over Natalie's half-subsumed head. She let out one last cry that was quickly muffled under the rubber, and as the gown's blue surface finally sealed up over the black, the petals of a decorative rosette emerging around the protruding bulge, the black latex sank into the contours of Natalie's face, turning her features into one of the ring of mask-like faces around the gown.  
The queen smiled broadly as she looked down at the newly-joined slave embedded in her dress. Reverberating through the material , she could feel Natalie squirming and wriggling in her tight rubber prison, along with the other slaves encased in her wondrous slave-gown...
