Selfish Symbiosis

"Remember, we must not be found. When we're in sight of others we must act like nothing happens" The thing said to itself before focusing to make clothes, something more fitting with it's mission of spreading... it choosed, leather boots, red lace stockings with garters, an almost non existant skirt, no underwear and finally a black leather jacket with another red shirt. "Now we're gonna catch some of those friends with this, for sure... time to catch a prey!"

It stepped out of Sunset's house, the feel of the air and the sun on the skin made it feel comfortable but also hungrier for pleasure and power, the only thing that it wants for living and for feeding. It knows what it wants and knows exactly how to get them; as it watched on Sunset's memories about her friends and what they do and like to do.... it will use those memories for itself.

It was walking down, checking Sunset's phone to see who was it going to catch first. It had an idea, but had to make sure that no one could find it spreading itself on more alive beings.

"Sunset!" Twilight yelled from behind. "Good morning! How was your study session"

"It were great, but felt tired and went to sleep very soon. You know boring studying things" Sunset answered, trying to keep it cool and disguising it was the thing that was talking for her; not that she has another choice but let it have the full control.

"Well, at least you have it under control" Twilight answered before checking Sunset up and down. "Wow, Sunset; i didn't knew you liked this kind of clothing. Isn't it a bit too... revealing"

Sunset cleared her throat. "Listen, Twilight; sometimes a woman just wants to show her true self and this is my way to show my own self to the world" Said with a convincing tone and a small wave of her hips. Twilight watched those hips wave, before her phone rang, to amke her check who was.

"Oh sorry, i have to go. I have to go see my brother and Cadance; see ya later" Twilight waved and run away, Sunset waved back but her face changed to a full annoyed face.

"We fucking hate you" It said before going back to the phone and look for it's prey; who already was selected as soon as she checked the phone again. As it has control over Sunset's body now it can move faster and can last longer on running, basically can't get tired anytime soon; and with that as a blink it reached it's destination and knocked at the door... staying there until it's prey opens the door.

The door opened slowly, letting the sun go in even more slower. "Sunset?... why are you here? it's.... too early" Fluttershy said between yawns, she was only wearing a shirt with her right shoulder completely uncovered, her nipples were visible through the shirt and also pink panties were at sight.

"Sorry i came without saying anything, but i need some help with something and i was hoping you could help me out" Sunset's voice was calmed, enough to make Fluttershy want to help; but that was not needed as the girl was practically recently awake.

"Well ok... come in, but... i may not make too much attention to you" She letted Sunset go in and shutted the door; it looked at Fluttershy's body from head to toe and licked her lips. Fluttershy yawned again. "So... what do you need help with?"

"We need help with..." it grabbed Fluttershy from the crotch and then the shoulder and pulled her closer to it. "... this!" Fluttersy felt the grab and that woke her up instantly. Fluttershy turned her head a bit and looked at Sunset, who's clothes were changing from what she was wearing to what it looked like a red and black latex body suit with her teeth more sharpen than before, as it could be seen as it was smiling... wide open.

"S-S-Sunset?!" She was petrified with fear, that was not her friend; she could tell about it, it's strength was not normal. In just a blink she was pushed against the floor with Sunset at top of her with a menacing look in the eyes. "Y-you're not Sunset... what do you want from me?" Fluttershy asked, trying to force herself out of the control of the thing.

"Sunset is here, with us. Don't worry, i won't hurt you... i just want a kiss" It leaned it's head closer to Fluttershy's; who just wanted to look away but couldn't... Sunset's body reached to kiss her, Fluttershy did not follow the kiss as she was being forced to do it. Then, Fluttershy felt something pushing to her mouth, it was a tongue that it was making it's way through the lips, Fluttershy thought that it would only play with her mouth, but no... the tongue continues the way to her throat until Fluttershy was starting to choke. It leaned the head up and with that the tongue came out of Fluttershy's mouth who coughed hardly. "Tasty... yes, you will have a good use to our plan" It claimed looking at her

Fluttershy kept coughing a little more, and then she felt like she was flying. When she recovered a bit saw that the thing had some sort of tentacles attached to the ceiling to make them go up, then it put 2 more tentacle things on her wrists and ankles and ripped her clothes exposing her body. "P-please... just let me go" Fluttershy asked but her voice wasn't strong enough to make it stop... not at all.

"Cease your fight, we'll take control on you. Forget about all..." It prepared it's crotch and placed it against Fluttershy's "... and feel like you're flying" It started to rub both of their pussies together, as fast as it could; making Fluttershy's body feel warmer; it started spreading on Fluttershy's body, inside her pussy and up her waist, slowly crawling to the scared woman's mouth, she saw it getting closer keeping her mouth closed as much as she could... until a moan escaped her mouth, with that open, it went inside her mouth; now it could reach her braind and submit her.

As it started to take control over Fluttershy, her body shakes for a brief period of time until it stopped. The tentacles that were keeping her wrists, detached freeing them; the first thing she made when having her hands free was holding her breasts squishing them. She also got the same sharp shaped teeth and long tongue, they both looked at each other's eyes and kissed while introducing each other's tongue inside their mouths and throats. As it was also inside Fluttershy's body, she was now able to not choke, so she could have it as deep as humans can't take it, that heat she was feeling helped for it to cover all of her body... once she had it covering completely, both of them squirted and screamed of pleasure.

Fluttershy was still herself, just a puppet under the control of the thing that controls Sunset, it grabbed Fluttershy from the chinn gently and looked into her eyes. "You will not spread to others, you will listen to my call. We're the only ones that will spread... so you will still act like you always do, but a little more hot than before. Understood?"

"I understand" As she answered, both of them were back in the floor, it turned her clothes back to the stockings and leather boots and jacket, Fluttershy stayed with her new form a bit longer and pleased herself a bit more. Then it left the house and walked back to home so could plan the next move.

"Maybe being this aggresive is not ok" it thought to itself. "Maybe for the next one i can use some other tricks" With one down, it gained a bit more power and after this encounter now also knows what it has to do to not call attention even more
