Incubus

Vapor Trail woke up the next morning and she went to the bathroom, she looked at herself in the mirror and saw her abdomen was back to its normal size, she grunted and clutched her groin when she felt her bladder was suddenly full, her urine dripped out and she quickly sat on the toilet to use the bathroom, she winced at feeling the worm slither out of her bladder and came out of her meatus, the worm wrapped itself around Vapor Trail's clitoris and constricted around it, Vapor Trail grunted and the worm then pressed its tip against the tip of her clitoris. Vapor Trail exclaimed and almost fell off the toilet, the tentacle loosened itself and slithered back into Vapor Trail's bladder, she breathed a little harder and she flushed the toilet, she took a shower and got through it with no problems, she put her makeup on and stretched to get ready for the day, she finished and flew to the Wonderbolts Academy.

Vapor Trail flew at the Wonderbolts Academy and did the stunts,

"Wait a minute, come on down here, Vapor Trail." Spitfire said, and she flew down to her,

"Hmm, you actually already lost all the weight, I guess you just had a bloated stomach, sorry for yelling at you the other day." Spitfire said, Vapor Trail blushed at the thought,

"Well, go on and keep flying, Vapor Trail." Spitfire said, and she flew back. Vapor Trail flew and did the courses while she felt her body telling her her bladder was full, she clutched her hind legs as tightly as she could,

"You okay, Vapor Trail?" Rainbow Dash asked, Vapor Trail blushed,

"I... I have to pee." Vapor Trail said,

"Oh, well, try to focus, training's almost done." Rainbow Dash said, and they did the training and finished. Vapor Trail headed to the mares' bathroom and sat on the toilet, the worm came out instead and Vapor Trail exhaled a little while the worm came out, Vapor Trail watched it and dark red veins appeared on it, Vapor Trail watched and her urine began to fall out and land into the toilet, Vapor Trail realized the worm was controlling her body's urinary system, it made her urine come out of her body like a downpour, the other Wonderbolts heard Vapor Trail's urine splashing in the water and they looked into the hallway, Spitfire flew into the mares' bathroom and knocked on the stall,

"Vapor Trail, you alright in there? Vapor Trail?" Spitfire asked, Vapor Trail blushed while she looked down, the worm stopped controlling her urinary system and she urinated normally,

"Yeah, I'm fine." Vapor Trail replied,

"You sure?" Spitfire asked,

"Yeah." Vapor Trail replied,

"Alright, just checkin' on you." Spitfire said, and she left. Vapor Trail finished using the bathroom and left after washing her hoofs, she sat at the table since she was not hungry, the other Wonderbolts murmured about her until lunchtime ended, Vapor Trail and the other Wonderbolts did training for the rest of the day until it was time to go home. Vapor Trail arrived home and got ready for the wedding, she took a shower, brushed and flossed her teeth, put on her makeup, and then her outfit, it was a long-sleeve blue lace dress with flower designs and a white dress under it, the gown had an elastic band at Vapor Trail's waist, she wore sparkly blue high heels on all four of her hoofs, and blue flowers in the left side of her mane, she decided not to style her mane and tail since she thought they looked good enough, she left her home and locked the door and then flew to the wedding.

Vapor Trail sat at the wedding near the back of the cathedral with a stallion to her left and a mare to her right,

"Wow, you're beautiful." the stallion said,

"*chuckle* Thank you." Vapor Trail replied, the wedding began and the marriage officiant began speaking, the wedding went on for sometime and Vapor Trail began to hear squishing noises in her groin region and she slouched forward with her hind legs on the floor, she watched the wedding continue and her eyes widened when she realized the tentacle and worm were beginning to control her reproductive and urinary systems. Vapor Trail clutched her groin and her hind legs shook, she saw her vaginal fluids, menstrual blood, and urine soak her dress and get on the blue high heel shoes on her front hoofs, she soon felt her own clitoris erect and her groin began to throb slowly, she watched the wedding with a shocked expression, her eyes were wide open and tears began to fall from them,

"You okay?" the stallion whispered as he touched Vapor Trail's shoulder, she got a little startled but soon regained her composure,

"I... I have parasites in my lady parts." Vapor Trail whispered while her entire face blushed,

"Parasites?" the stallion asked, Vapor Trail nodded,

"One in my womb and one in my bladder." Vapor Trail whispered, the stallion watched and saw the body fluids from Vapor Trail's groin soak her dress,

"Can you please not look?" Vapor Trail whispered,

"Sorry." the stallion whispered, and the wedding continued while Vapor Trail tried to stop her body fluids, she began to slide out of the chair and the stallion and mare sitting to Vapor Trail's sides held her up, four of the ponies sitting in front of Vapor Trail turned back and their jaws dropped at seeing Vapor Trail soak her dress. The wedding finished and the tentacle and worm continued to control Vapor Trail's body systems, the mare held her up and she and the stallion carried her,

"Come on, let's get you to the doctor." the mare said, and she and the stallion helped her walk while Vapor Trail continued to clutch her groin.

Vapor Trail sat outside the doctor's waiting room while the stallion and the mare accompanied her, the tentacle and the worm continued to control her body systems and make her soil her dress, the other patients looked at her and Vapor Trail looked away while blushing, she continued to clutch her own groin while she waited. The door opened and the doctor came out while his patient walked away,

"Vapor Trail." the doctor said, and she walked while the stallion and the mare helped her, she entered the doctor's office and the door closed. Vapor Trail sat while covering her own groin and the doctor stood across from her,

"Alright, what exactly is the problem?" the doctor asked,

"I... have worm-like creatures in my body, they're in my private parts." Vapor Trail replied while blushing,

"How many?" the doctor asked,

"Two." Vapor Trail replied,

"What do they look like?" the doctor asked, Vapor Trail closed her hind legs while blushing even more and she looked away, the tentacle and the worm slithered out of her groin, they went over and under Vapor Trail's front hoofs and lunged towards the doctor. The doctor ducked and dodged the two, he moved to the other side of the room and the tentacle and worm could not reach him,

"I know what you have, this is a creature known as an incubus, they enter female bodies and take control of their body systems depending on which orifice they enter, here, I have a book on them." the doctor said, and he opened a book and threw it across the floor to Vapor Trail. Vapor Trail looked down and read the entry on the incubus,

"A hostile creature that has plagued Equestria since ancient times, they enter a body and take control of the host's body systems depending on which orifice they enter. Since the incubus is male, it enters into the female orifices, mainly the mouth, the anus, or the vagina, when entered into the mouth, the host begins to have saliva form at a rapid rate and vomit uncontrollably, host may belch constantly as well, when entered into the anus, host may experience constant defecation and flatulence, when entered into the vagina, host may experience discharges and periods at random times, it is also the incubus' preferred orifice to enter. Incubi are carnivores, they feast on the brains and hearts of others, after eating a certain amount, the incubus will birth a worm-like creature, this is also an incubus, this creature mutates the host's body, victim experiences more vomiting, belching, defecation, and flatulence when they enter the mouth or anus, but if the main incubus is in the vagina, the mutating incubus will go into the host's bladder and they may experience constant and uncontrollable urination. The incubi are known for being cruel to their hosts, they often take control of the host herself or her body functions at inconvenient times in an attempt to embarrass or humiliate her, refusal to obey them will make the incubus begin to stab its tip inside the host's body to cause damage and try to show their dominance over the host, incubi are sex-driven carnivores and can only be removed from the body after it is dead." Vapor Trail read, she looked up at the doctor,

"See, there you go, and sorry to say this, but I can't remove it, the spines will tear your vaginal wall if I try to pull it out." the doctor said,

"What about the small one?" Vapor Trail asked,

"It's a bit hard to grab, and that one tends to resist." the doctor replied,

"Can you at least try?" Vapor Trail asked, and the doctor got ready, he approached slowly and grabbed the worm, Vapor Trail exclaimed when she felt the doctor's touch transfer through the worm and to her urethra, the doctor tried to pull the worm out and Vapor Trail began to let out exclaims, she slid onto the floor and threw her hind legs around, the doctor continued pulling and the worm resisted and Vapor Trail exclaimed as she began to urinate her dress faster,

"Okay, let go, please." Vapor Trail said while blushing, and the doctor did,

"You'll also have to be careful if those two get hurt, the pain will transfer to your groin region too." the doctor said, Vapor Trail looked at her own groin while the tentacle and worm went back into her body,

"Um... what were these things?" Vapor Trail asked,

"There was a tribe of them a long time ago, they're the male members, a female tentacle is called a succubus, it enters into the bodies of stallions." the doctor replied,

"What does it look like?" Vapor Trail asked,

"It's on the other page of the book of the page you're on now." the doctor replied, Vapor Trail looked and saw a picture of the succubus, it looked just like the incubus but a lot smaller, she read that the succubus can enter the stallion's body through either his mouth, his anus, or his penis, Vapor Trail read and saw the symptoms for being in the stallion's mouth and anus were the same as a female having an incubus in her body, and the succubus inside a stallion's penis makes him experience uncontrollable urination and ejaculation, she also read that succubi did not make the worm-like creatures appear out of their bodies and they mutate the stallion on their own,

"Sorry, but I can't help you." the doctor said,

"It's okay." Vapor Trail replied,

"Well, you should try to find a way to kill the incubi, then remove it, it'll be much easier." the doctor said,

"Okay, thank you." Vapor Trail replied, and she flew out of his office,

"Well?" the mare asked,

"The parasite's a creature called an incubus." Vapor Trail replied,

"I see, come on, let's get you home." the stallion said,

"It's fine, I can get there on my own, thank you, both of you." Vapor Trail replied, and she flew home.

Vapor Trail arrived home and soaked her dress in cold water to clean her body fluids off of it, she scrubbed the shoes she wore on her front hoofs, she cleaned her body fluids off of the shoes and got ready for bed, she slept and had more wet dreams, she and Sky Stinger were having sex again and she woke up when Sky Stinger ejaculated, she looked and saw her vaginal fluids on her blanket again, she sighed and took her blanket off. Vapor Trail tried to sleep but she had another dream where the tentacle and worm came out of her body, the tentacle was in her mouth and she was sucking it while the worm constricted itself around her clitoris and pressed down on the tip, Vapor Trail let out muffled moans in her dream and the tentacle moved back and forth faster while the worm tightened itself around Vapor Trail's clitoris, she let out more muffled moans and grunts, she let out a grunt when she felt her vaginal fluids come out and a white semen-like fluid came out of the tip of the the tentacle and its spines. Vapor Trail sprung awake and shrieked, she covered her own mouth and clitoris with her front hoofs, she looked and saw more of her vaginal fluids on the bed, she groaned and fell back onto the bed and passed out.
