Symbiotic relationship

A few hours had passed since Rarity's bottom had been spanked by Sym as Rarity stood in front of a mirror. Rarity turned around so her back was to the mirror as Sym removed the skirt and panties part of her clothes so she could see how pink her bottom was.

Sym created a hand from the back of her top to hold her tail out of the way to give her a better view. "A beautiful bottom and a lovely shade of pink" Sym said as he released her tail and recreated her skirt and panties.

"Just out of curiosity Sym," Rarity said, "can you do that thing that Twilight made you do earlier?".

"You mean that symbiotic futa thing?" Sym asked, "hmm possibly you want me to try?".

Rarity turned around to face the mirror "yes please darling I want to know if you can do it without Twilights device". Remembering the strange sensation he had when the device was scanning him. A little while later the skirt disappeared and he slowly grew the cock on the panties before he started touching Rarity's pubic area. His body started to attach to her skin as the DNA of them started to merge causing Rarity to feel her new appendage.

Rarity grabbed her new cock as she felt the new feelings that came with it. "This is different," she said as she slowly stroked it. Sitting down on a chair she opened her legs as she played with her cock. "Can you make a pair of balls to go with this cock?" she asked pointing to the empty space where there should be balls.

"Hmm let me see," Sym said as he concentrated before a pair of balls started to form.

Rarity gently grabbed the balls shivering as she felt the sensation "oo you connected them to me too nice" she said. She picked up speed as she masturbated her cock while rolling the balls in her other hand. "Mm I could cum from this" Rarity said as her hand moved faster as she was desperate to cum with this new sensation. Before she could reach her orgasm a knock on the door interrupted her.

Sym quickly disconnected his body from Rarity and made the male genitals disappear while bringing back the skirt.

Shaking a little Rarity stood up and walked to the door to open it.

Fluttershy was on the other side of the door as Rarity opened it. "I'm not interrupting anything am I?" Fluttershy nervously asked.

Rarity let her in "oh no darling" Rarity said internally cursing "what can I do for you?".

After Rarity closed the door Fluttershy turned around "I'm just not too sure about the new underwear you gave me". Fluttershy dropped her skirt and pulled her top off leaving her in her underwear. Her panties were more close to a high waist thong and her bra looked tiny compared to her generous sized boobs.

If Sym had a mouth he'd be drooling by now at the sight.

"Do these seem small to you?" Fluttershy asked embarrassed.

Rarity motioned her fingers for Fluttershy to turn around.

As Fluttershy turned around Rarity and Sym saw how much her thong was swallowed by her ass cheeks.

"Not at all dear," Rarity said, "it shows off your body beautifully".

Fluttershy put her hands behind her back as she faced Rarity "it's embarrassing plus what Stallion would want to see me?".

Rarity placed her hands on Fluttershy's shoulders "oh I know someone, dunno if he's a pony but I can tell he'll like what's in front of me".

"Please I know you're trying to cheer me up but" Fluttershy started to say.

Rarity put a finger to Fluttershy's lips "tell me Fluttershy would you like to finally lose your virginity? this being I know would gladly make you feel like your in heaven". She removed her finger from Fluttershy's lips "want me to introduce you to him?" she said almost seductively.

Fluttershy couldn't help but nod a little "Rainbow kept saying how good it feels and keeps teasing me about it but I'm scared it'll hurt".

"Oh he'll make you feel like your on cloud nine" Rarity said wrapping her arms around Fluttershy's back and he'll be gentle right Sym?". As she said that Fluttershy felt a third hand touch her pussy on the outside of her thong gently caressing her. A click could be heard as Rarity undid Fluttershy's bra allowing her boobs to spill free from their confinements. As the bra fell a pair of hands that came from Rarity's top gently touched her boobs feeling their softness and their weight in each of the palms.

"Quite endowed," Sym said "and beautifully delicate to touch too" his finger carefully sunk into the flesh of her boobs. Two more hands grabbed her thong and pulled them down before running up her legs until they came to a rest on her bottom. The first hand traced her pubic hair as it felt them spring under his touch. He moved his hand to her pussy and made a lip on his finger to kiss her pussy.

Fluttershy gasps as she felt the kiss.

Sym's fingers ran along the slit of her pussy creating the texture of a tongue on his fingers. Slowly his fingers started to enter her pussy slipping a little bit in each time.

"Feels good doesn't it?" Rarity asked "judging from your expression I'd say you've never touched yourself either you poor thing".

The hands on Fluttershy's breasts turned into mouths as they started sucking on them as the fingers on his other hand finally reached the knuckles inside her pussy.

"You must be so pent up," Rarity said, "don't worry Sym'll take good care of you".

Sym slowly pumped his fingers inside of Fluttershy's pussy. He wanted to put some in her ass but decided against that as he didn't want to put her off.

Once Fluttershy was wet enough he removed his fingers and retracted his hands that were coming from the lower clothing parts.

"Could you turn around and bend over a little please?" Sym asked.

Fluttershy closed her legs to allow her Thong to drop to the floor before she turned around and bent over.

The hands came out and held her bottom open a little to see her pussy and anus clearly. "Beautiful," Sym said "are you ready to become a mare?" he asked.

Fluttershy nodded "be gentle ok?".

Sym shifted the lower clothing part into one blob that connected to the shirt. He retracted some of the top giving Rarity a low cut version of her shirt as he reformed his lower part. Sym was able to reform the lower half into a makeshift lower torso with arms extending from its waist. Holding his cock he placed his remaining hand on Fluttershy's waist as he rubbed the tip of his cock against her pussy. He slowly inserted his cock into her pussy adjusting its size to minimise the pain he might cause. He slipped his cock into the gap that the hymen didn't cover and then slowly increased his cock size to gently break it.

Fluttershy gasped as she felt the movements inside of her as her hymen slowly broke.

Rarity saw the reaction and looked down and saw the blood run down Sym's cock. "Congratulation darling," she said as she played with her own pussy.

Allowing Fluttershy to get used to the feeling Sym slowly started moving his cock in and out of her pussy.

"Ah that feels weird," Fluttershy said "kinda good weird".

Sym started to move faster making Fluttershy's breasts start swinging back and forth.

"Don't hold back darling cum" Rarity said, "I bet Sym wants to taste you".

As it was her first time Fluttershy couldn't hold back any longer as her back arched as she came giving Sym his first taste of her. "Oh wow, that felt," Fluttershy said, "that felt good".

"Would you like to cum again darling?" Rarity said.

Fluttershy nodded "yes please".

"Sym could you" as she was about to finish her sentence he attached himself to her groin and linked up with her senses of touch as he grew a cock complete with balls for her. Rarity slowly slipped her cock into Fluttershy's pussy as Sym created a pair of hands to reach around and grab Fluttershy's boobs. "Oh wow Fluttershy you feel good" Rarity said as she entered her. Rarity started moving her hips "Feels different to when I did Twilight" she said, "I wonder if this is what it's like for the stallions".

Fluttershy was in too much pleasure to hear what Rarity was saying as she rapidly approached a second orgasm.

Rarity was close too due to her male masturbation from earlier.

As the two girls came they couldn't help but arch their backs as Sym drank their juices.

After they got their breaths back Sym detached from Rarity and reformed into her clothes.

Rarity then helped Fluttershy put her clothes back on before Sym gently grabbed Fluttershy's butt.

"Don't put yourself down" Sym said giving her ass a cheeky squeeze "you have a beautiful body that matches your wonderful personality". He played with her butt for a bit "trust me if I had a body I'd be taking you anytime you wanted and in any way you wanted".

Fluttershy blushed "thanks," she said, "maybe we can do this again?".

Sym's hands finally left her butt as she left Rarity's house.

After Rarity closed the door Sym made the skirt and panties disappear "ready for another spanking?" he said.

Rarity knelt down and placed her ass in the air as she rested her face on the floor "do it darling".

Several hands came out as they started using her bottom as a set of drums. Some inserted themselves into her pussy and ass as the rest started making her bottom red.

"Mm work those fingers and make that bottom red" Rarity said.

As he spanked her bottom red Rarity slowly drifted off to sleep from the pleasure she was receiving.

After drinking his fill he grew a pair of legs and walked Rarity upstairs to her bedroom. Once inside he placed her on the bed and changed into her nightwear before pulling the covers over her.
