Symbiotic relationship

Underneath a clothing store in Equestria a hidden lab was working away on various tests, some for the good of Equestria and some that can potentially cross the lines, a handful of scientists were working on a new clothing material as they took several samples of materials from silk to even rubber and chucked them into the container.

One scientist was wheeling a large pod with a red pony inside who had no hair or tail "be careful you don't knock anything while you wheel test no 69" said a scientist who was mixing some chemicals, "yeah yeah I know we don't want any accidents happening" said the one wheeling the pod "besides why would I want to harm the results of the potential new guard for our Princesses?".

The pony in the pod was an artificial pony that had been made in case the Princesses needed more guards when more are unavailable, it was on a life support being moved from one section to another so they can test it, as the scientist wheeled the pod near the container for the new clothing material an explosion happened at one of the computers nearby.

The scientist that was mixing chemicals was sent flying as his vials went into the container mixing into the substance, the scientist that was wheeling the pod was sent flying with the pod as he hit the wall the pod landed on top of the container as the glass to the pod broke.

The body fell into the mixture as the emergency crew came in to put out the fire.

"Everypony you must leave," said one of the crew members. "Emergency lockdown, we'll access the damage after its safe to do so". As they left they didn't notice a strange red substance coming out of the container as it made its way to an air vent.

The red Rubbery looking substance made it way through the vents to the ground floor of the clothing store's warehouse where it slipped through the vent unconscious into an open crate that a machine sealed afterwards, a pony that worked in the warehouse came up and put the label on the crate and put it into the truck.

The truck delivered the crate to Rarity's Boutique as she had placed an order of clothes and materials to work with after the truck driver placed the crate inside Rarity went up for a shower.

The substance regaining conscious "hungry" it mumbled as it pushed up the lid slipping through the gap it made and slide upstairs into Rarity's bedroom.

Rarity came out of her shower with nothing but a towel on as her wet hair rested on her back as she entered her room, after she dropped her towel to the floor she saw the red blob on her bed "oh what's that?" she asked approaching it.

The blob jumped onto her covering her body from the neck down as it shaped itself into a bodysuit.

Rarity looked in the mirror "hmm colours a bit much but this does hug my figure well" she turned around "it does show off my beautiful bottom though" she said squeezing her breasts together.

Rarity jumped though when she felt something enter her pussy and ass-hole "whoa what the?" she said as her breasts felt like they were being grabbed by somepony, she fell to her knees as the insertion inside of her started moving "whoa slow down not so fast" Rarity said as it stimulated her clitoris.

The neck area grew up until it covered her mouth and entered her mouth kinda like a kiss with a tongue and a cock fucking her mouth simultaneous, a voice rang out from the suit "don't worry I won't hurt you I just need some food" it said.

Her body collapsed as she came and after a while, the parts inside her mouth, pussy and arse were retracted, "Thank you" said the voice as Rarity sat up "I'd been starving for a while" it continued.

Rarity tried to use her magic to remove the thing but it was to no avail "Sorry but we're bonded for now" the voice said, "and sorry for earlier but for some reason my food requirements are mares sexual juices" it continued.

Rarity didn't hear the last part straight away "well you could at least look like decent clothes if we're stuck together, like my clothes there" she pointed to the bed, "Wait what did you say you eat?" as she said the suit morphed itself into a matching pair of Rarity's clothes as it matched its colours.

"Trust me I wish I knew myself let alone how I can do this," he said finishing changing into her new clothes.

"What are you?" Rarity asked as she touched his clothes like body as she looked in the mirror.

He lifted the skirt part of him to reveal the part of him that became her panties "don't know some kinda of living clothes? or a symbiote?" he said, he shifted the panties to the side to have a look at her pussy in the mirror as Rarity grabbed the skirt to pull it down.

Being a part of his body she couldn't move the skirt so her hands moved to her pussy to cover it "pervert" she said.

He readjusted the skirt and panties back to there normal positions "sorry but it how I'm made to be apparently" he said quickly lifting the top up to reveal he didn't copy her bra and to flash her breasts. Finishing his fun he said "you shouldn't be ashamed you have a nice body, it feels nice hugging it like this".

Rarity felt like a pair of hands were on her bottom when he said that, "so do you think we can be separated?" she asked kinda hoping to still be together for potential costume ideas.

"Kinda hard to say," he said while making a cock inside her panties and rubbed it between her legs and against her pussy.

Rarity let out a gentle moan as he grinded against her "ok how about a name you do have one right?" she asked.

It thought for a second "how about Sym Suit or Sym for short" he said drinking the new juices that Rarity's pussy was making.

"Ok Sym you can make my body your home but you must not defile me when I'm in public, with my friends or while I'm working you got it?" Rarity said.

Entering his cock into her pussy he said "I can't promise if I get very hungry but if push comes to shove I'll be discreet about it".

Rarity grabbed a small book on the different clothes she wears plus those she wanted to wear "I suppose that'll do now please finish eating if that's what you're doing as I have some work to do" she said.

Sym pumped her fast as she lifted the skirt to see the crotch area of her panties going in and out like it was getting fucked from the outside, Rarity soon came again as Sym drank up her nectar "thanks, I'm done for now" he said allowing Rarity to carry on with her day.

Rarity was thinking about what costumes to make him change into as she recovered from her orgasm as she headed downstairs, "maybe this ain't too bad I can save money on new clothes at least" she said as she reached the box "did you come from here?" she asked noticing the lid slightly open.

Sym looked at the box "yes I fell I there due to passing out from hunger" he said as she opened the box.

Rarity retrieved some materials for a dress she was making and placed them on the table next to the dress. It was quite late when Rarity finished her dress but she did enjoy having the new company as they spoke while she headed up to her room, "Sym darling can you change into this?" she asked pointing to her nightgown she had hanging up in her closet.

Sym quickly changed into her nightgown.

"Wow do you also change materials?" she asked feeling the change on her skin.

"I think so but I don't really know-how," Sym said as Rarity lied on her bed.

She opened her legs a little " I'm guessing you want a little more?" she said feeling the satin-like fabric move between her legs.

"May I?" he asked getting a bit hungry at the thought of a quick nighttime snack.

"Sure darling but can you make it feel like a tongue this time?" she asked him, without saying a word he made a tongue that starting licking her pussy causing her to moan in pleasure.

"I think we might have the start of a wonderful relationship," she said biting her finger, Sym drove his tongue in deeper manipulating it around and hitting all the areas in her pussy.

Her back arched high as she came "oh wow you do know how to please a lady" she said slowly slipping off the sleep.

Sym drank up her juices as she fell asleep "I'll be sure to wake you up" he said drifting off too.
