A fantastic little series by Rubbermatt about some really, really tight nylon.

Only Nylons by Rubbermatt

can’t see, can’t hear, can’t speak, so many layers …
Totally encased, mouth filled with balled up hosiery, bound hand & foot, with the Infernal Device purring away softly deep inside her, Kathleen writhed helplessly, back arching in a private rhythm, sinking deeper & deeper into subspace.

Hubby often brought work home with him, in the form of Lytex & Smartex outfits that needed to be tested.
Kathleen had been an eager guinea pig for many of their most successful products, making suggestions for improvements based on her exhaustive testing sessions.
Over time the outfits had grown increasingly sophisticated & she had spent more & more time completely encased, until she had left her job to become a full time test subject.
Kathleen was now encased 24/7, stress testing prototype developments, some of which went deliciously wrong, leaving her trapped for weeks until the scientists figured out how to release her. Unfortunately, so far, they had been 100% successful.
However, the rumours about this new Smartex/Lytex fusion hybrid with an unknown organic component had potential.
The researchers were over enthusiastic about the new material, even darling hubby had been sucked in, for Kathleen it represented the possibility of her deepest, darkest fantasy becoming reality.
The next gen Lytex suit she was testing responded to the spike in her arousal, tightening all over & expanding the plugs inside her. She writhed against her wonderfully taut restraints and moaned in delight ….

The new material had been everything Kathleen had dared to dream it would be.
The prototype suit had fit her perfectly, the smart semi-organic sheath adapting and shifting to hug every inch of her without any wrinkles or creases, regulating her temperature & recycling waste.
The parts of the suit that intruded deep inside her had been equally as delightful, swiftly learning what made her tick & taking her to unbelievable heights of pleasure. Previous suits had been pretty good at this, but the new one took it to an all new level.
All went swimmingly until they tried to get her out of the suit to run tests. And couldn’t.
Not an uncommon occurrence with prototypes, no one was particularily worried as they got Kathleen up on the table & started scanning.
What they sawed shocked them this time, the suit had extruded millions of cillia & entered every single pore in her skin, as they zoomed in they could see it growing in real time, branching & extending into her.
It had taken root in her.
Scanning her entire body the researchers could see the intruders within her growing as well, slithering all the way into her.
The encased woman began to thrash and writhe at the intense sensations, so they quickly moved to restrain the hapless woman, much to her delight, then began wracking their brains.
Kathleen writhed & squirmed helplessly, completely seamlessy sealed, tightly restrained, she could feel the living suit extending itself into her, slithering under her skin, belly rippling as the roots from the anal plug delved ever further through her innards, neck bulging as the gag extended tendrils down her throat, the pleasure & pain combined pushing her over the edge into a brain melting orgasm ….

“Any luck?”
“None whatsoever. Pincers can’t get a grip, it’s basically fused with her skin from crown to toe.
Can’t get a needle through it either. The Smartex/Lytex combo would be tough enough anyway, but this living synthesis stuff is pretty much impenetrable. We could try to brute force thru, but that would cause serious physical trauma, & we’re not sure how it would react to that kind of physical attack.”
“Understood. What about the scanners?”
“No problem there, we can see inside her fairly well. The entity has done a fairly remarkable job of subsuming Kathleen & making her an integral living part of itself.”
“And Kathleen?”
“Alive, well, & currently drowsing in post-orgasmic bliss. We are noticing signs of growing physical distress though.”
“Strange, normally you can leave her sealed & bound for days.”
“We suspect it may be hunger & thirst, she has been through a rather intense transformational experience, not to mention being fucked senseless over a period of hours. We’re going to try the usual method getting some fluids into her whenever she got herself stuck in a prototype.”
“Think that’ll work with this .. whatever it is?”
“Well, although her mouth & nose appear to be completely filled she’s still breathing quite freely through them, so we’re hoping it’s water permeable as well.”

“Is it working?”
“The entity seemed confused at first, then Kathleen roused & tried sucking the fluid, at which point it cottoned on fast & began transferring the stuff into her stomach.”
“Any attempt at contact by Kathleen?”
“Nope, she’s still on Cloud Nine, she won’t be remotely coherent until tomorrow at the earliest.
In fact it looks like the entity is keeping her in an induced state of heightened post orgasmic bliss. Maybe to keep her quiescent while it finishes taking over her body, maybe just to get her to rest & recuperate. We won’t really know until we’re able to talk to her.”
“Are we keeping her like this?”
“Nope, we’ve got that old containment room we use for photoshoots, we’ve sterilised it, spooled up the big fabber & replaced the seals & gaskets, got it back up to medical grade. We hauled a big slab of memory foam in it to serve as a bed.
It’s a bit stark but once she’s been fed I don’t think Kathleen is going to care much about anything except sleep. It’ll do for now & we’ll get some amenities sorted out once we’ve all had some rest.”

Not even a murmur when they released the restraints & carefully lifted Kathleen & her ‘guest’ onto the makeshift gurney.
They did elicit a small nod & a tired thumbs up when they gently explained she would be staying in the observation room.
There was a soft sigh as they gently laid her on the bed, then a happy little moan as she realised they’d put latex sheets on her bed.
As the door quietly closed there was silken rasping & squeaking of latex as Kathleen sensuously writhed on her bed, then she curled up with a satisfied sigh & was out like a light.

“Morning our gorgeous little hybrid beauty!”
mmmnnmmmm
“Hungry?”
MMMHHHHMMMM!!
“We’ll send breakfast in.”

The woman on the other side of the glass box watched with rather envious eyes as the encased woman writhed delightedly, caressing her rubbery lycra-like sheathed body as she slithered over the latex sheets.

Standing outside the cell, taking notes, Alice looked up as the tone of Kathleen’s moans changed.
The blonde frowned, peering in, then her eyes widened as she saw the encased woman’s belly bulge, then subside, then bulge ..
“Oh my, the suit is … how big does a willy have to be to make a girls tummy distend like that …. oh gods, she’ll have two of those in her, and the urethral sound … no wonder she’s getting noisy. Lucky cow, wish that was me in there.”

“Hey Kath, I brought breakfast!
It’s just that nutrient broth you’ve had before, but they went whole hog on improving the taste & adding different flavours.
Also got that magnetic pad & stylus so you can ’talk’ & a bunch of books.
Everyone’s sorting thru stuff for some creature comforts without cluttering the place up too bad, you’ll still want to be able to move in here.”

nod nod thumbs up
