Day 1

Vapor Trail was doing Wonderbolt training for the day and she did the training courses, she flew alone since Sky Stinger was away to see his family and will not be back for a while. Vapor Trail flew with the others and was about to call it a day, she thought about a wedding she was invited to and was looking forward to it,

"And halt!" Spitfire said, they stopped flying,

"Good work, that's all for today, we'll continue tomorrow." Spitfire said, and they all finished and went to the locker room. Vapor Trail took a shower while still thinking about the wedding she was invited to attend, she finished taking her shower and packed up to go home,

"You look happy today, Vapor Trail." Rainbow Dash said,

"I am, I'm going to be going to a wedding a few days from now." Vapor Trail replied,

"That awesome, even though weddings are boring for me." Rainbow Dash said,

"I'm really looking forward to it, I already bought high heels, a dress, and flowers to wear in my mane for the event." Vapor Trail said,

"Well, hope you have a good time, I'll be leaving now, see ya, Vapor Trail." Rainbow Dash said,

"Okay, bye." Vapor Trail replied as Rainbow Dash flew out of the locker room. Vapor Trail hummed as she finished putting her uniform in her locker, she closed her locker and began flying home.

Vapor Trail flew home and was over the woods, she admired the view of nature and the animals, she kept heading home but stopped when she saw an earth pony mare laying on the ground, she had a dark red coat, long messy black mane and a black tail, her eyes were closed, and her cutie mark was a rose, Vapor Trail saw she was covered in blood, so she flew down to her. Vapor Trail landed on the ground and walked to her,

"Um, excuse me." Vapor Trail said, the mare opened her eyes, they were red,

"Are you okay?" Vapor Trail asked, the mare looked at her and opened her mouth, a creature came out of her mouth, it was light pink, had spines all around its body in two swirling patterns, a black tip, and shaped like a tentacle, the creature was slimy and thick. The creature's tip entered into Vapor Trail's mouth and she gagged as she grabbed it with her front hoofs, its slimy exterior made Vapor Trail unable to grip it, so she tried to use her wings to grab it and managed to. Vapor Trail fell over and gagged as the tentacle tried to slither down into her throat, she let out muffled grunts as she struggled to get the tentacle out of her mouth, she pulled it out and inhaled loudly, she tried to fly away but the tentacle wrapped around her abdomen and pulled her down, she exclaimed as she fell onto the ground. The entire tentacle came out of the mare's mouth and her eyes changed from red to pink, Vapor Trail used her wings to grab the tentacle and get it off of her, its cold and slimy body made her feel uncomfortable, she got ready to fly away but the tentacle quickly lunged up and wrapped around her left hind leg, Vapor Trail screamed as it pulled her down and slammed her onto the ground. Vapor Trail panted as she recovered from the pain and the tentacle slithered up her hind leg and made its way to her groin, Vapor Trail screamed when she felt the tip of the tentacle on her vagina, she swung her legs around and freed her hind leg from the tentacle, she rolled over onto her back and she exclaimed as she felt the tip of the tentacle in her vagina. Vapor Trail tried to grab it with her front legs but it slid through her hoofs and she exclaimed as the tentacle continued slithering into her orifice, her vaginal fluids began to come out while the tentacle started to go inside of her faster, the entire tentacle was soon inside her uterus and Vapor Trail clutched her groin as she groaned in pain and cried, she rolled over while clutching her groin, she soon began flying and headed home.

Vapor Trail sat at the table all by herself and had dinner while thinking about the tentacle in her body, she had soup and ate slowly,

"Eek." Vapor Trail said as she winced forward and felt the tentacle slithering around inside her uterus, she shuddered with great discomfort as she heard squishing noises inside of her own vagina and the tentacle was cold, she had more soup and she suddenly did not want to eat it anymore, she stopped eating and left the bowl on the table and went to bed. Vapor Trail laid in her bed and tried to sleep, she had dreams of her and Sky Stinger having sex, Vapor Trail moaned with ecstasy in her dream until Sky Stinger ejaculated. Vapor Trail woke up and gasped, she looked and saw a wet spot on her blanket, she shrieked when she felt a strange sensation in her body and the tentacle in her body had black veins appear on it and Vapor Trail's eyes turned red,

"Wha... What's going on?!" Vapor Trail said as her body moved on its own, and she got out of bed and began moving against her own will.

Vapor Trail flew outside into the night against her own will and she could not do anything while the tentacle controlled her,

"No, stop." Vapor Trail said as she flew on her own and saw herself going to the store, she flew in and broke the window, she flew around and looked for contact lens,

"What?" Vapor Trail asked, and the tentacle went through the colors and eventually found one that matched the color of Vapor Trail's eyes and put them on. Vapor Trail looked at herself in a mirror and saw the contact lenses were a perfect match of her eye color, she flew out of the store quickly while exclaiming, she flew around and looked around frantically,

"Hey. What are you doing?" Vapor Trail asked, and she stopped flying and saw a muscular earth pony walking around,

"Hey, baby, why don't you let me explore your body?" the earth pony asked in a slurred speech, and a unicorn mare ran away from him. Vapor Trail watched him but soon felt discomfort in her genital region, a cold and slimy liquid came out of her vagina, she realized the tentacle was drooling, it made her fly down to him and the drunk earth pony went to her,

"Hey, beautiful, can I..." the earth pony said, Vapor Trail kissed him on his lips before he could finish his sentence, Vapor Trail gagged a little since his breath stank, she finishes and he let out a short breath. Vapor Trail touched his shoulders and pushed down onto his hind knees, Vapor Trail reeled up onto her hind legs, she used her front hoofs to hold the stallion's head still, the tentacle lunged out of Vapor Trail's vagina and went into his mouth. The stallion gagged while Vapor Trail had an orgasm and held onto the tentacle, black veins glowed on it and it began throbbing. The stallion gagged and struggled while the tentacle used its tip to cut roof of his mouth and made its way into his brain, Vapor Trail continued to have an orgasm while the tentacle slithered out of her vagina more as it traveled into the stallion's brain, it severed the stem of the brain and began to eat his brain. The stallion fell over dead while Vapor Trail looked on speechless and horrified, the tentacle came out of the stallion's mouth and then stabbed into his left chest and severed the veins on his heart, he grabbed the heart with its mouth and slithered back into Vapor Trail's vagina while blood dripped from the heart, it controlled Vapor Trail and made her fly home while it ate the stallion's heart, Vapor Trail arrived home and she went into bed and slept.

Day 2

Vapor Trail woke up the next morning and she was still speechless, she looked at the news and saw the store the tentacle made her break into and the dead stallion with his brain and heart missing, Vapor Trail remembered the previous night and tears rolled down her cheeks. Vapor Trail headed into the shower and began to cry a little,

"What have I done?" Vapor Trail asked, and she stood in her bathtub while the hot water fell on her, she scrubbed her mane with her wings and exclaimed and almost fell over, the tentacle emerged from her vagina a little and was pressing its tip against her clitoris, she reeled up onto her hind legs and grabbed the tentacle with her front hoofs. The tentacle pressed its black tip on her clitoris and it soon began circling itself around it as slowly as it could, Vapor Trail moaned while she tried to stop it by holding onto it, the tentacle then began pressing its tip against her clitoris' tip after it finished circling around it, the tip opened into four sections and it closed itself and began sucking on Vapor Trail's clitoris. Vapor Trail exclaimed and held onto the wall with one hoof and her bathtub with the other hoof since she almost fell over, the tentacle sucked Vapor Trail's clitoris and she moaned while her vaginal fluids began to drip and go into the drain, the tentacle soon stopped and went back into her vagina. Vapor Trail panted and sweated, she turned the shower off and dried herself, she tried to have an apple for breakfast but did not feel like eating it, so she put it back in the refrigerator and flew to the Wonderbolt Academy.

Vapor Trail did her Wonderbolt training and her vaginal fluids dripped anytime she looked at a stallion, she did training while blushing and hoped nopony would notice, training finished and everypony took a break. Vapor Trail sighed and looked at the groin area of her uniform, and to her relief, there was no stain, the tentacle took control of her again and her eyes turned red, but they looked like her regular eye color due to her contact lenses, she moved around against her will and walked elsewhere. Soarin took off his uniform and took a break before the next training session began, he heard walking and saw Vapor Trail coming,

"Hi, Vapor Trail, how are you doing?" Soarin asked, Vapor Trail grabbed his shoulders and then the back of his head and tried to kiss him,

"Whoa, Vapor Trail, I'm not ready for a relationship, yet." Soarin said as he moved back, she grabbed him with her front hoofs and tried to put him onto his hind knees, he fell and she began to move his head towards her genital, he pushed her back and she fell, Vapor Trail exclaimed as she fell over,

"Whoa there, Vapor Trail, I'm not ready for that, I don't know why you're acting this way, but it needs to stop, I'll have to kick you off the Wonderbolt team if you don't." Soarin said, and he flew away. Vapor Trail walked around and looked for more stallions, she saw Fire Streak and walked to him,

"You okay, Vapor Trail?" Fire Streak asked, and she tried to move his head down and towards her own groin area, he grabbed her with his wings and pushed her away, he quickly flew away, Vapor Trail flew after him but he lost her in the clouds. Vapor Trail flew back down and looked for more stallions, she tried to call for help but the tentacle made her silent, nopony was around and the tentacle stopped controlling her, she panted and regained her senses, she went into the academy and went to the bathroom, she urinated with no problem, she then looked at herself in the mirror and she saw no abnormalities in herself, she looked down at her own groin and saw vaginal fluids hanging out of her groin, she got a paper towel and wiped it away, she put the towel in the trash bin and headed outside.

Vapor Trail did more flying courses and her vaginal fluids dripped again whenever a stallion was in her sight, the tentacle took control of her again and she flew out of course,

"Vapor Trail!" Spitfire said, and she flew after Silver Zoom and got onto his back as he grunted, she turned him around and tried to kiss him, he forced her off of himself and Vapor Trail then flew after Thunderlane and tried to hold him in place, he grunted as he used his hoofs and wings to get her off of himself,

"Vapor Trail, what are you doing?!" Rainbow Dash asked, she flew after Wind Walker next and tried to get a hold of him, he flew away as fast as he could while Vapor Trail flew after Star Hunter next,

"CEASE TRAINING!!" Spitfire yelled, and they stopped while the tentacle stopped controlling Vapor Trail,

"COME HERE, VAPOR TRAIL, FRONT AND CENTER!!" Spitfire yelled, and she flew down to her,

"WHAT WERE YOU DOING BACK THERE?! YOU WERE GIVEN A SIMPLE TASK AND YOU MESSED UP!! YOU BETTER GET YOUR ACT TOGETHER, OR I WILL BOOT YOU OFF OF THE WONDERBOLT TEAM!!" Spitfire yelled, Vapor Trail looked down,

"That is all for now, we'll try again later." Spitfire said, and they all went into the academy.

Vapor Trail was in the locker room with the other mares and she looked at her uniform and saw the stain on the inside from her vaginal fluids, she felt her vaginal fluids dripping again and she quickly went to the bathroom, she sat on a toilet and clutched her groin while holding toilet paper in an attempt to make her fluids stop, thoughts about the stallions at the academy flashed in her head and she thought of them as food, the tentacle began drooling again and it fell from Vapor Trail's vagina and onto her inner hind thighs. Vapor Trail yelped as she felt the drool, it was cold and dripped down slowly, she wiped it away with the toilet paper and her vaginal fluids and the tentacle drooling did not stop, she gasped when she felt another fluid come out of her vagina, she looked and saw blood, she began looked on speechless and horrified at seeing the tentacle change and control her body's systems, she continued to try to stop all of the fluids coming out of her vagina. Knocking was heard at the stall's door,

"Vapor Trail? You okay?" Angel Wings asked,

"I'm fine." Vapor Trail replied,

"Really? You don't sound fine." Angel Wings said,

"I am, I'm just using the bathroom." Vapor Trail replied,

"Alright, just checking, everypony else is worried, too." Angel Wings said, and she walked away. Vapor Trail continued to try to clean her genital region and the fluids stopped dripping, she sighed and cleaned herself, she put the toilet paper in the toilet and flushed it all down, she exited the stall and saw the other mares looking at her,

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

"Yes, I'm fine." Vapor Trail replied, and she walked away while the other mares watched her.

Vapor Trail went to the mess hall and sat alone, she looked at the vegetables and was not hungry, she looked at the water bottle and was not in the mood to drink it, she sat and waited for lunch to end, she did more training and the day finished soon. Vapor Trail began to fly home and flew over the woods again, she exclaimed when the tentacle slithered in her uterus and took control of her again, she flew down and walked on the woods, she stood above a den of prairie dogs, she closed her eyes and exhaled a little when she felt her vaginal fluids fall out and onto her hind inner thighs, the tentacle came out and went into the den. Vapor Trail tried to fight back being controlled and the tentacle went deeper into the den, she heard squeaking and panicking,

"N... no, p... p... pl... ease... stop." Vapor Trail said as she fought the tentacle's possession of her, she continued to hear squeaking, she tried to cancel out the noises she heard of them being torn apart, the squeaking stopped and the tentacle came out all bloodied and holding a dead prairie dog in its mouth, the tentacle moved forward and tried to make Vapor Trail eat the dead prairie dog, she fought its control and resisted, the tentacle threw the prairie dog onto the ground and then slithered back into Vapor Trail's vagina, it stayed out partially and began pressing its tip against her clitoris, she exclaimed as it pressed harder and blood began to drip out,

"I'm... not... eating it." Vapor Trail said, the tentacle then moved above her clitoris and began circling itself around her vaginal wall, Vapor Trail cringed as the cold and slimy tentacle went around her vaginal wall as slowly as it could, Vapor Trail began to shiver as the tentacle made its way and finished circling her vaginal wall, it then got the dead prairie dog and tried to make her eat it again, she sighed and gave in and the tentacle shoved the dead prairie dog into her mouth, she gagged as she chewed it, she tasted its organs and raw meat as she forced herself to eat it, she managed to swallow it and coughed, she exclaimed as the tentacle took control of her again. Vapor Trail flew around the woods and the tentacle looked for more animals to eat, it stuck itself in the air and smelled the particles in the air with its own body, it saw rats in the woods walking around, the tentacle made Vapor Trail fly down and it grabbed one rat with its mouth, it squeaked and died instantly and the other rats ran away, the tentacle swallowed the rat whole and made Vapor Trail fly after the others, it ate whatever rats it could catch, Vapor Trail winced and cringed as the tentacle slithered in and out of her vagina to reach the rats that were close and far to her, the tentacle ate ten rats and got one last rat and shoved it into Vapor Trail's mouth, she gagged as the tentacle controlled her and made her chew and swallow the dead rat, she groaned as she got a headache. Vapor Trail regained control of herself after the tentacle finished using her, she sighed in relief in being able to control herself again, but she exclaimed again when the tentacle had black veins appear on itself and began throbbing slowly, she exclaimed each time it throbbed since it stretched her vaginal walls a bit, the tentacle's spines dug into her vaginal walls and her senses almost overloaded from the spines touching the nerves, it slithered back into her vagina slowly and Vapor Trail shuddered as the cold and slimy tentacle went back into her body, it went back in and Vapor Trail took a few minutes to regain herself, she opened her wings and flew home.

Vapor Trail went through her refrigerator and was not hungry when she looked at what she usually ate, she looked at her milk bottle and did not want to drink it, she suddenly felt tired and laid in bed. Vapor Trail tried to sleep but began to feel strange in her groin region, she grunted as her genital region throbbed up and down, Vapor Trail tried to sleep while her genital region continued throbbing as her skin stretched out upward as she laid down, but the sensation was too strong for her to ignore and she clutched her own groin as it stretched and throbbed, she felt her own clitoris erect and it touched her hoofs, she exclaimed since her clitoris was currently hypersensitive, she almost passed out from her senses being overloaded. Vapor Trail grunted and exclaimed as her genital region stretched out and throbbed throughout the night, she fell asleep after the throbbing and stretching stopped after about ten minutes and had a dream. Vapor Trail dreamed about having sex and there were three stallions in her dream, she looked and saw the three were Sky Stinger, Soarin, and Thunderlane, Vapor Trail was having intercourse with Sky Stinger, she was performing fellatio on Soarin, and having anal sex with Thunderlane. Vapor Trail let out muffled moans and grunts in her dream and she continued having sex in her dream and the three stallions ejaculated at the same time while Vapor Trail began gagging since Soarin's semen got stuck in her throat and she could not breathe, she struggled for breath in the dream. Vapor Trail woke up and sprung up from her bed, she felt a wet spot on her blanket at her groin region and saw a stain, she sighed and moved the blanket off, she had breakfast, used the bathroom, took a shower, brushed and flossed her teeth, put on her makeup, and then flew to the Wonderbolts Academy.

Day 3

Vapor Trail did the flying courses and her vaginal fluids dripped again and distracted her, she focused on the obstacle course and finished,

"Very good, Vapor Trail, you're already improving after the disaster that was yesterday." Spitfire said,

"Please, I don't want to be reminded of that." Vapor Trail replied while blushing,

"Anyway, next course." Spitfire said, and they flew while the Wonderbolts watched Vapor Trail suspiciously. Vapor Trail flew with no problem, the tentacle did not take control of her and the day went smoothly, she finished the course and performed perfectly, the Wonderbolts went to the mess hall and watched Vapor Trail, she did not eat since the vegetables looked unappealing to her now, the tentacle took control of her and made her walk to the mares' bathroom. Vapor Trail sat on the toilet and she exhaled as she heard squishing noises inside her own vagina and her vaginal fluids fell out and into the toilet, the tentacle came out of her uterus and moved itself back and forth, Vapor Trail continued to breathe a little hard while the tentacle moved back and forth like a stallion moving his foreskin while masturbating, it went in and out of her vagina and black veins appeared on the tentacle again and began throbbing. The tentacle made Vapor Trail grab it and she began moving her front hoofs on it as if she was a masturbating stallion, Vapor Trail closed her eyes and opened her mouth since she could feel the physical contact with the tentacle go to her vaginal walls, she let out an audible exhale as she moved back onto the toilet seat. Banging was heard on the door and Vapor Trail yelped as she jumped on the toilet seat,

"Vapor Trail!! What are you doing in there?!" Spitfire asked,

"Nothing." the tentacle made Vapor Trail say,

"That doesn't sound like nothing! Open up before I bust the door down!" Spitfire said, and the tentacle went back into Vapor Trail's vagina as quietly as it could, it made her open the stall and Spitfire was glaring at her,

"What are you doing?!" Spitfire asked,

"Using the bathroom." Vapor Trail replied,

"Then why do we hear you moaning and squishing noises?" Spitfire asked,

"Uh..." Vapor Trail said,

"Don't tell me you're pleasuring yourself." Spitfire said,

"Uh..." Vapor Trail said while blushing, Spitfire pushed her aside and she exclaimed, she looked into the stall and it looked clean,

"This is a warning, Vapor Trail, if you get any of your fluids in the bathroom, you're gonna clean the entire bathroom from the floor to the ceiling, do I make myself clear?" Spitfire asked,

"Y... yes, ma'am." Vapor Trail replied,

"Good, get ready now, break's almost over." Spitfire said, and she left, Vapor Trail flushed the toilet, washed her hoofs, and headed back out.

Vapor Trail did the flying courses for the rest of the day and performed flawlessly, she went home when it was time to leave and flew away. Vapor Trail headed home but the tentacle took control of her again and guided her, she flew to a college and she saw a rat walking around on the ground, she flew down and smashed the rat with her front hoofs and the rat squeaked, she sat on her hind legs and the tentacle came out of her vagina and began eating it. A unicorn mare who was a student at the college spotted Vapor Trail and tried to see what she was doing, she looked and saw the blood on the ground, she heard the squishing noises and looked more carefully while thinking she was giving birth. Vapor Trail stopped moving and so did the tentacle and part of the dead rat hung down, the mare's eyes widened and she quickly trotted away, Vapor Trail looked back and did not see anypony, the tentacle redirected her and had her hold the rat while the tentacle ate the rest of it. Vapor Trail flew up and looked at the classes to look for the mare who spotted her since the tentacle sensed her nearby, it looked into the classes and spotted the mare who saw her, she had an ultramarine blue coat, long bluish-white mane and tail with silver and periwinkle colored glitter in them and a transparent veil all around her mane and tail with light red and white flowers in them, her eyes were a deep blue and she had light pink eye shadow and eyeliner on, her cutie mark was three cosmetics, which was lipstick, an eye shadow brush, and an eyeliner pencil, she had pink heart earrings in each ear and a gold necklace. Vapor Trail watched her and stopped for a while to admire her beauty, she flew away and waited for the day to pass, the bell rung and the unicorn left the college and walked home, Vapor Trail followed her and saw her home, she flew away and went to her home.

Vapor Trail arrived home and did not eat nor drink anything, she got the ready to wash the rat blood off of her front hoofs, but the tentacle slithered out of her vagina and pressed its tip against her clitoris, she exclaimed as the tentacle continued to press itself against her clitoris and it began to erect a little, she gasped when she felt herself urinate since the tentacle made her lose control, her urine got onto the tentacle and the floor, she focused and tried to wash her hoofs, but the tentacle pressed itself against her clitoris harder and she yelped, she got ready to put her hoofs under the water and the tentacle's tip opened into four sections, they closed and began sucking on Vapor Trail's clitoris. Vapor Trail exclaimed loudly and she began moving her hind legs around, her hoofs slid on her own urine on the floor and she held onto the sink so she would not fall, she moved her own face towards her front hoofs and the tentacle sucked her clitoris more lightly, Vapor Trail realized what the tentacle wanted her to do and her eyes widened with horror, she licked the blood off of her own front hoofs and she forced herself to swallow it. The tentacle stopped sucking her clitoris and Vapor Trail went to go get paper towels to clean her urine off of the floor, but the tentacle sucked her clitoris again, she yelled and fell onto the floor since there was nothing to hold her up this time, she got ready to clean the floor with the paper towels but the tentacle sucked her clitoris harder and she exclaimed, she dropped the paper towels and her face fell into her own urine puddle, the tentacle lightened its sucking of her clitoris, Vapor Trail gasped,

"You wouldn't." Vapor Trail said, the tentacle sucked her clitoris harder again, she exclaimed since it felt like the tentacle's sucking was going to rip her clitoris out of her body, she closed her eyes and forced herself to drink her own urine while crying, she finished and cried more as she laid on the floor. It was night time and the tentacle took control of her again and went back into her vagina, Vapor Trail headed outside and flew to the home of the unicorn who spotted her earlier.

Vapor Trail arrived back at the home of the unicorn who saw her earlier, she watched her through the window and saw her sitting on her bed and reading through a magazine on beauty tips, Vapor Trail flew to another window and checked to see if it was unlocked, it was not, so she flew to another window, it was also locked, so she flew to another window faster than usual, it was also locked, Vapor Trail flew even faster to another window and it was locked, the tentacle made Vapor Trail grab the window and force it up and break the window's locks, she entered and closed the window and flew around the house. The unicorn heard the loud noise from the window lock breaking and looked up from her magazine, she put it down and got off of her bed, she walked to her door but it flew open and its own and Vapor Trail entered her room,

"Whoa!" the unicorn said as she jumped back to avoid getting hit by the door flying open, she fell back and looked on. Vapor Trail moaned and grunted as she wrestled with the tentacle to free herself from its control,

"Are you okay?" the unicorn asked,

"G... go!" Vapor Trail said,

"What?" the unicorn asked, Vapor Trail moaned as she reeled up on her hind legs, the unicorn gasped when she saw white, thick fluids coming out of Vapor Trail's vagina,

"I... I'm not in control of myself." Vapor Trail said, and the unicorn stood there and looked on while speechless. Vapor Trail lunged forward and knocked her down, she shrieked when she fell, Vapor Trail covered her mouth with her front right leg and put her hind legs between the unicorn's, the tentacle came out of Vapor Trail's vagina and it slithered towards the unicorn. The unicorn let out a muffled scream and her a pink aura appeared around her horn and she flung Vapor Trail off of herself, she got up and began to run to the window, the tentacle quickly slithered out of Vapor Trail's vagina more and wrapped around her left hind leg, she yelped when the tentacle pulled her back and made her fall, the unicorn yelled as the tentacle pulled her back, she tried to grab onto something and pull herself but there was nothing. The tentacle pulled the unicorn towards Vapor Trail wrapped her front legs around the unicorn's chest when she was in front of her. The tentacle moved itself off of the unicorn's leg and puts its tip into the unicorn's vagina, she got ready to scream but Vapor Trail quickly covered her mouth, the unicorn let out a muffled scream before the tentacle stopped, it soon began slithering into the unicorn's vagina as slowly as it could, the unicorn moved her hind legs back and forth and she let out a loud, muffled groan as the tentacle went farther into her vagina slowly. The unicorn threw her hind legs around as the tentacle slithered into her vagina, clear fluids began to come out, the unicorn let out a loud grunt as the tentacle slithered into her uterus deeper, black veins appeared on the tentacle again and it began throbbing, Vapor Trail moaned from feeling the tentacle's sensation of being inside the unicorn get transferred to her vaginal walls. The tentacle slithered out of the unicorn as slowly as it could and it came out while still throbbing, it slithered across the unicorn's vagina and she let out a muffled moan, the tentacle opened its mouth and began sucking the unicorn's clitoris. The unicorn let out a loud muffled grunt and Vapor Trail began to have an orgasm, she moaned loudly while her vaginal fluids dripped and got on her inner hind thighs and on the floor, the unicorn heard the squishing noises and saw Vapor Trail's vaginal fluids, she felt a tear on her right shoulder and looked and saw Vapor Trail crying,

"I... I'm sorry." Vapor Trail said, and the unicorn grunted more as the tentacle sucked on her clitoris and she let out a muffled scream when she felt the skin on her clitoris get sucked harder, she looked down and let out a muffled gasp at seeing blood on the tentacle's mouth, the tentacle bit her clitoris and sucked harder and more blood came out, she let out a muffled scream as she felt her clitoris get stretched out and about to be severed, the tentacle stopped sucking and stabbed its tip into her clitoris, the unicorn screamed and the tentacle stabbed deeper into her clitoris and she bled profusely. The unicorn screamed in agony and Vapor Trail put her down and quickly turned her around, the tentacle forced itself into her mouth and began digging through her head and to her brain, it took it out and ate it, it came out of her mouth and then stabbed into her chest to get her heart and ate it. Vapor Trail cried at seeing what she did, but the tentacle quickly took control of her, slithered back into her vagina, and made her fly home.

Vapor Trail laid in bed and tried to sleep, but the tentacle came out of her vagina and moved itself up and down on her clitoris, Vapor Trail grunted and exclaimed as the tentacle continued rubbing its cold and slimy body on her clitoris, the spines around it stabbed into her clitoris a bit. Vapor Trail grabbed the tentacle with her front hoofs and wings and tried to move it off, but it slid through them and continued rubbing itself on Vapor Trail's clitoris. Vapor Trail moaned loudly and she felt her own clitoris erect, her vaginal walls began throbbing, so did the tentacle, and the black veins reappeared, vaginal fluids began to leak out of Vapor Trail's vagina and the tentacle's spines expanded a little. Vapor Trail felt a few of the spines stab into her front hoofs, wings, and clitoris, she felt something warm and sticky, she looked and saw a white fluid coming out of the tentacle's spines, the tentacle throbbed more and expanded, she winced at feeling the spines dig into her vaginal walls, Vapor Trail exclaimed loudly and the tentacle began to throb quickly, its mouth opened and the white fluid came out, it fell onto Vapor Trail's abdomen and the tentacle slithered back into Vapor Trail's vagina. Vapor Trail panted and looked at the white fluids on her and her vaginal fluids that soaked her bed sheets, she began to lose consciousness and fell asleep.

Day 4

Vapor Trail woke up next morning and did not eat breakfast, she took a shower and brushed her teeth, she then combed her mane and tail and put her makeup on, she flew out and heard news everywhere about the unicorn the tentacle made her kill last night, she got a newspaper and looked at the article, she read that the unicorn's parents have been distraught and want justice, Vapor Trail held her tears back and flew to the Wonderbolts Academy. Vapor Trail flew and did the courses, she felt the tentacle expand in her uterus and her abdomen stuck out a little, she blushed and hid her face while the other Wonderbolts took notice of it,

"Come on down here, Vapor Trail." Spitfire said, and she flew down to her,

"Are you pregnant?" Spitfire asked,

"No." Vapor Trail replied,

"Then lose the weight!" Spitfire said while raising her voice, Vapor Trail winced and closed her eyes at the loudness of her voice,

"Well, get back to flying, I want that weight of yours gone in two weeks." Spitfire said, and Vapor Trail flew back to the others. Vapor Trail flew and did the courses while others murmured about her expanded abdomen, Vapor Trail continued to blush and look away, she did the courses and break time came. Vapor Trail went to the mares' bathroom and took her uniform off, she saw her slightly expanded abdomen and felt it, she felt the tentacle's spines through her body, she winced at the feeling and felt the tentacle throbbing a little, Vapor Trail controlled her breathing and left the bathroom to have lunch. Vapor Trail ate very little and had to force herself to eat something, the others watched and she winced at feeling the tentacle throb inside of her, she dropped her fork and closed and rubbed her hind legs together, the other Wonderbolts watched her and Vapor Trail just sat and waited for lunch to end, she did more flying courses until it was time to go home.

Vapor Trail arrived home and soon began to grunt and scream, she fell onto the floor and rolled over to be on her back, she clutched her own groin since that was where the pain was located, the tentacle slithered out of Vapor Trail's vagina and she gasped at how much bigger it was, the tentacle moved slowly and pressed its tip against Vapor Trail's clitoris, she tried to pull it off with her front hoofs but could not get a good grip on it, Vapor Trail exclaimed and yelled as the tentacle rubbed its tip on her clitoris, it got off and the tentacle began to contract, its tip opened into four sections and a thin black worm-like creature fell onto Vapor Trail's abdomen. Vapor Trail breathed with relief at the contractions stopping, the worm-like creature began to slither on Vapor Trail's body, she quickly grabbed it but it was slimy and slid through her grasp, the worm pressed its tip on the center of Vapor Trail's clitoris and she grunted as it made her clitoris erect, the worm slid farther down and over her clitoris, she lost control of her bladder again and began to urinate and it touched the worm, it slithered down farther and turned around, the urine touched the tip of the worm, it followed the trail and went into Vapor Trail's meatus and into her urethra. Vapor Trail screams as her genital area lifted off of the floor and she moved her head side-to-side,

"No." Vapor Trail said as the worm slithered deeper into her urethra, Vapor Trail moaned loudly as the worm went in deeper, the entire worm soon entered into her urethra and made its way into Vapor Trail's bladder while the tentacle went back into her vagina, she panted and tears fell from her eyes again, she looked ahead and saw her dress for the wedding, which was tomorrow, she panted from the amount of energy the birth of the worm took, she caught her energy back and went to the bathroom. Vapor Trail looked at herself in the mirror and did not notice any changes in herself, she began to close her eyes, she walked and stumbled to her bed, she laid down in it and fell asleep.

Day 5

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.

Day 6

Vapor Trail woke up the next morning and took a shower and put her makeup on, knocking was heard at the door and it opened,

"Vapor Trail, I'm back." Sky Stinger said,

"In a minute, I'm in the shower." Vapor Trail said, and she finished and walked out after drying herself,

"Hey, sorry I'm late coming back, there were a lot of problems with my family." Sky Stinger said,

"Really? What happened?" Vapor Trail asked,

"My mom was ill, my dad got laid off from work, my oldest sister is getting ready to move out, my other sister needed help finding a job, and my two younger sisters needed help with school, bullied and grades." Sky Stinger replied,

"My, you must be exhausted." Vapor Trail said,

"I am, everything just started settling down yesterday." Sky Stinger replied,

"How are things?" Vapor Trail asked,

"My mom's getting better, my dad knows how to clean the house now, my oldest sister moved out, my other sister found a job and has an interview coming up, and my two younger sisters are doing better in school." Sky Stinger replied,

"That's good, well, I hope your sister does good at her interview." Vapor Trail said,

"Yeah, or I'll have to help her look for another job." Sky Stinger replied, Vapor Trail felt a desire to kiss Sky Stinger and seduce him along with making him perform cunnilingus on herself, she shook her head,

"You okay?" Sky Stinger asked,

"Yeah, I've been busy recently, too." Vapor Trail replied,

"Sorry I didn't make it on time to go to the wedding." Sky Stinger said,

"It's okay, anyway, try to relax, Sky Stinger, I'll make you some breakfast." Vapor Trail replied,

"Thank you, I haven't eaten anything in over a day." Sky Stinger said, and she made a fruit salad for him and he ate it, the two then flew to the Wonderbolts Academy together.

Vapor Trail flew for the day and she tried to focus since looking at the stallions made her want to seduce them,

"Vapor Trail, focus." Sky Stinger said, she looked forward and flew below an obstacle just seconds before she flew into it, she continued to get distracted and looked at the other stallions, she flew while not paying attention and almost hit Rainbow Dash,

"Vapor Trail, keep your eyes on the course." Rainbow Dash said,

"Oh, sorry." Vapor Trail said, and they flew more, they finished with no problem,

"Vapor Trail!" Spitfire said, Vapor Trail looked down and flew to her,

"What are you doing?! Why are you staring at the stallions?!" Spitfire asked,

"Um..." Vapor Trail said,

"You're lucky there were no mistakes this time, but you better watch yourself next time." Spitfire said, Vapor Trail flew away while Spitfire glared at her. The Wonderbolts did more training and Vapor Trail smiled with drool coming out of her mouth at the sight of stallion flanks in her view, they finished the courses and Vapor Trail got ready to enter the mess hall but stopped when she heard a conversation,

"Vapor Trail's been acting strange this past few days." Angel Wings said,

"How?" Sky Stinger asked,

"She's been flying off course and chased after stallions one day, she's loud in the bathroom, too." Rainbow Dash replied,

"Did it start as soon as I left?" Sky Stinger asked,

"No, not as soon as you left, maybe about four days after you did." Angel Wings replied,

"I'll see what's wrong with her." Sky Stinger said,

"Thanks, Sky Stinger, she won't say anything to us." Rainbow Dash said, and Vapor Trail walked to the mess hall. Vapor Trail sat at lunch on her own and Sky Stinger walked to her,

"Vapor Trail." Sky Stinger said, Vapor Trail faced him,

"I've heard about how you've been acting recently, what's gotten into you?" Sky Stinger asked,

"I..." Vapor Trail said, the worm slithered out of her bladder and pressed its tip on her clitoris hard, she clutched her groin and grunted, the Wonderbolts looked at her,

"You okay?" Sky Stinger asked,

"Can you excuse me a moment?" Vapor Trail asked,

"Sure." Sky Stinger replied, and Vapor Trail flew to the bathroom. Vapor Trail entered a stall and she tried to pull the worm off of her clitoris, but it slithered back into her bladder and it and the tentacle took control of her again and began making her masturbate. Vapor Trail began rubbing her own vulva and she exhaled slightly, her vaginal fluids began to drip and get on the bathroom floor while Vapor Trail fought for control over her own body and tried to stop herself. Vapor Trail continued to rub her vulva and began stimulating her own clitoris shortly afterwards, Vapor Trail exclaimed and was about to have an orgasm before a loud knock was heard on the door and it startled Vapor Trail,

"VAPOR TRAIL, WHAT ARE YOU DOING IN THERE?!" Spitfire asked, Vapor Trail blushed and did not answer,

"You better open the door before I bust it down!" Spitfire said, Vapor Trail looked down at the floor and blushed even more. Spitfire tackled the door open with her shoulder and saw Vapor Trail's vaginal fluids on the floor,

"VAPOR TRAIL!!" Spitfire yelled, Vapor Trail reeled back,

"THIS WHOLE TIME, YOU'VE BEEN MASTURBATING IN THE BATHROOM?!" Spitfire yelled, Vapor Trail whimpered while sweating,

"Get the mop and clean this up, you're on janitor duty." Spitfire said, and she flew away. Vapor Trail looked down and flew to get the mop, she cleaned her vaginal fluids off of the floor and proceeded to clean every stall in the mares' bathroom, she finished and Spitfire was in front of her,

"Clean the stallions' bathroom now." Spitfire said, Vapor Trail looked down and went in. Vapor Trail looked at the stallions' bathroom and prepared herself for how messy it would be, she mopped the floor and slowly opened the stalls, but she noticed the stallions' bathroom was actually pretty clean, she sighed with relief and cleaned the toilets, she finished after several minutes and got ready to put the mop back, but the tentacle and worm took control of her again and made her fly over the bucket full of water and they made her masturbate over it,

"N... no." Vapor Trail said, she tried to fight for control over her own body and clenched her own hind legs together to stop her vaginal fluids from falling into the mop's water, the worm took control of her urinary system and tried to make her urinate into the mop's bucket, Vapor Trail closed her hind legs even tighter while her urine began to drip down her right hind leg, she slowly regained control of herself and flew over to the toilet, she relaxed her hind legs and she urinated into the toilet, she sighed with relief. The tentacle made her masturbate faster and she moaned while her vaginal fluids fell into the toilet water, the tentacle stopped while Vapor Trail panted and sweated, she regained control of herself and she flushed the toilet, washed her hoofs, and headed out. Vapor Trail moved the mop and its bucket and saw Spitfire in front of her,

"What took you so long?" Spitfire asked,

"Just making sure it was cleaned thoroughly." Vapor Trail replied, Spitfire looked in,

"Good enough, go do your training now." Spitfire said, and Vapor Trail flew outside, she did her training and went through the day with no more problems, she finished and headed home.

Vapor Trail sat and drank a lot of water, she looked out the window and saw the sun was setting, the tentacle and worm took control of her and made her fly outside. Vapor Trail flew up and looked for the stallion and mare who sat beside her at the wedding, alongside the doctor who explained to her what the tentacle and worm were, she did not see them and the tentacle and worm came out of her body and began throwing tantrums, they went back into her body and made her fly elsewhere. Vapor Trail arrived in the woods again and the tentacle and worm made her stomp on a mouse and kill it, the tentacle came out of Vapor Trail's uterus and stabbed its tip into the mouse's head to get its brain and eat it, it then pierced into the mouse's chest and ate its heart, it then made Vapor Trail eat the corpse and she gagged and almost spat it out, the tentacle went back into Vapor Trail's womb and made her fly around more. Vapor Trail flew around and looked for small animals to kill, she saw a skunk walking in the woods, the tentacle and worm made her fly down and slam her hoofs onto it to kill it, the tentacle came out of her vagina and ate the skunk's brain and heart, it forced Vapor Trail to eat the skunk, she gagged at the taste but managed to swallow it, the tentacle went back into her vagina and she flew around more. Vapor Trail flew around and saw a stallion walking around, he looked at the woods and Vapor Trail flew down to him,

"Hey, what are you doing all the way out here?" the stallion asked, Vapor Trail walked to him and grabbed his shoulders, she kissed him, feelings of ecstasy overrode his senses and he embraced her. Vapor Trail and the stallion kissed one another and Vapor Trail tried to regain control of her body and warn him, she let out muffled grunts and wobbled around, the two stopped kissing,

"Are you okay?" the stallion asked, Vapor Trail moaned while the tentacle and worm began to come out of her body, her vaginal fluids and urine began to come out of her body,

"What's wrong?" the stallion asked,

"G... go." Vapor Trail said as she struggled to speak,

"What?" the stallion asked,

"L... leave... for your own safety." Vapor Trail said, and she exclaimed again, she tried covering her groin with her front hoofs and wings, she then grabbed the stallion at his shoulders and pushed him down onto his hind knees,

"Hey, what are you doing?" the stallion asked, the tentacle and worm came out quickly and went into his mouth. Vapor Trail moaned and black veins appeared on the tentacle while dark red veins appeared on the worm and they throbbed. Vapor Trail experienced another orgasm while the two cut through the top of the stallion's mouth and made its way to his brain, the stallion let out muffled grunts as he tried to pull the two out of his mouth, they slid through his grip and he soon died. The tentacle and the worm slid out of his mouth while the tentacle had his brain in its mouth, it then stabbed into his chest and took out his heart and ate it, the two creatures went back into Vapor Trail's groin, they made her fly back home and she fell asleep.

Vapor Trail dreamed about having sex with Sky Stinger again and woke up when he ejaculated into her, she sighed and went into the shower, she took a hot shower while thinking about what she did last night, she looked down while she just stood in the shower, under the water. Vapor Trail reeled up on her hind legs and began to wash her mane, but she exclaimed and looked down, the tentacle and the worm were rubbing their tips on the sides of her clitoris. Vapor Trail exclaimed while she tried to pull the two off of her clitoris, but her hind legs slid around in the bathtub and she fell onto her back, she exclaimed and moaned while the two creatures continued rubbing themselves on Vapor Trail's erect clitoris, she moaned and grunted while she tried to grab them and pull them off, their slimy texture made them slide through her grip, she continued to exclaim and grunt as they continued stroking her clitoris. Vapor Trail's vaginal fluids began coming out and mixing into the water and going into the drain, she began moaning and her groin began throbbing, the tentacle and the worm stopped stroking her clitoris and went back into her womb and bladder. Vapor Trail panted while her groin throbbed and her vaginal fluids continued coming out, she covered her own groin and tried to stop her vaginal fluids, she sighed when her vaginal fluids stopped, she finished her shower, put on her makeup, had breakfast, and flew to the Wonderbolts Academy.

Day 7

Vapor Trail flew to the Wonderbolts Academy and heard the Pegasi talk about the stallion the tentacle and worm made her kill yesterday, Vapor Trail held her tears back and flew. Vapor Trail did the drills and she became controlled by the tentacle and worm, she flew after Sky Stinger and tried to kiss him while in midair,

"Whoa, Vapor Trail, what are you doing?" Sky Stinger asked, and she tried to restrain him so she could kiss and seduce him, he pushed her away and the tentacle and worm stopped controlling her. Vapor Trail panted and recomposed herself,

"What are you doing?" Sky Stinger asked,

"I..." Vapor Trail said, the tentacle and worm took control of her to make her silent,

"You've been behaving strangely, come on, Vapor Trail, let's finish our course, I'll have a talk with you later." Sky Stinger said, and they flew, Vapor Trail looked and saw Spitfire did not notice her messing up this time, she sighed with relief and flew again to finish her course. Vapor Trail sat at lunch and Sky Stinger sat with her,

"What's gotten into you, Vapor Trail?" Sky Stinger asked,

"I... I..." Vapor Trail said,

"Come on, Vapor Trail, spit it out, it can't be that bad." Sky Stinger said, Vapor Trail thought about the tentacle and worm in her body and blushed deeply,

"Are you on your period, Vapor Trail?" Sky Stinger asked,

"No, it's not that." Vapor Trail replied,

"Then what is it?" Sky Stinger asked, Vapor Trail continued looking at Sky Stinger and the tentacle began drooling, Vapor Trail quickly clutched her groin and closed her hind legs while blushing deeply. Sky Stinger looked and saw the tentacle's droll coming out of Vapor Trail's groin region,

"Oh, no wonder why, you've been aroused recently, it happens to all of us eventually, Vapor Trail." Sky Stinger said, the other Wonderbolts looked and saw the tentacle's drool on the seat Vapor Trail was sitting on,

"Are the others looking, Sky Stinger?" Vapor Trail asked as she clutched her groin and closed her hind legs as tightly as she could,

"Sorry, but yes." Sky Stinger replied, Vapor Trail blushed even more,

"Well, that explains why you've been chasing stallions." Spitfire said from behind Sky Stinger, he and Vapor Trail looked at her,

"You know the drill, Vapor Trail, you're on clean-up duty again." Spitfire said, Vapor Trail continued to try to stop the tentacle from drooling, it stopped and Vapor Trail went to go get paper towels. she soaked them in water and cleaned the tentacle's drool off of the chair she sat on,

"Wait, look." Angel Wings said, the Wonderbolts did and saw the tentacle's drool looked like semen,

"That doesn't look like something that would come out of girl's body." Rainbow Dash said, Vapor Trail finished cleaning while the other Wonderbolts murmured,

"Alright, Vapor Trail, since this is something you can't control, I'm going to have to ask you to sit out of training for now, you can go back in when this arousal phase of yours is over." Spitfire said, and Vapor Trail sat and waited for lunch to end. Vapor Trail flew again and the tentacle and worm took control of her immediately, she flew out of course and chased after the stallions at high speeds, the Wonderbolts exclaimed and screamed as Vapor Trail rammed through the mares and knocked them off course, Vapor Trail tried to kiss and seduce all of the flying stallions while she fought for control over her own body, they pushed her away and Vapor Trail flew after them while drool came out of her mouth. Vapor Trail tried to fly after the next stallion and Rainbow Dash restrained her,

"VAPOR TRAIL!! GET OVER HERE!!" Spitfire yelled, the tentacle and worm stopped controlling Vapor Trail and she flew down to her,

"I TOLD YOU TO SIT OUT!! WHAT WAS THAT YOU WERE DOING THERE?! YOU'RE FLYING AFTER STALLIONS AND KNOCKING OTHER PEGASI OFF THE COURSE, YOU COULD'VE KILLED SOMEPONY!! YOU HAVE CAUSED ENOUGH TROUBLE, UNTIL YOU FIX YOUR BEHAVIOR, YOU ARE DISMISSED AS A WONDERBOLT!!" Spitfire yelled, and she took her badge, the other Wonderbolts flew while Vapor Trail watched, tears fell from her eyes while she watched the others and she flew home while crying when it was time to leave.

Vapor Trail sat at the table at home and cried all afternoon, she got up when it was dark and began to head to her bed, but she stopped in her kitchen when she felt the tentacle and worm slithering out of her body, her vaginal fluids, urine, and the tentacle's drool soaked the floor. Vapor Trail closed her hind legs and clutched her groin with her front hoofs and wings, but the two came out and slid through her hoofs and wings, the tentacle went to the left side of her clitoris while the worm went to the right, the two began rubbing their tips on it. Vapor Trail exclaimed and moaned from the two creatures caressing her clitoris, she moaned more and fell onto her back. The tentacle began circling Vapor Trail's vaginal walls while the worm wrapped and constricted itself around Vapor Trail's clitoris and began pressing its tip against the clitoris' tip, Vapor Trail moaned loudly and the tentacle finished circling around Vapor Trail's vaginal walls, it opened its mouth and began sucking on Vapor Trail's clitoris. Vapor Trail moaned and grunted loudly as she threw her hind legs around and moved side-to-side on the floor, black veins appeared on the tentacle while dark red veins appeared on the worm, they began throbbing and a white semen-like fluid began dripping out of the tentacle's spines. Vapor Trail moaned and grunted extremely loudly in pain and her groin began throbbing, she let out a slight yelp and her groin throbbed back and forth quickly, the tentacle stopped sucking her clitoris and the worm unwrapped itself from her clitoris, they throbbed with her groin and a copious amount of the white fluid shot out of the tip of the tentacle and its spines, and the tip of the worm at high speeds, a copious amount of vaginal fluids, menstrual blood, and urine shot out of Vapor Trail's groin at high speeds as well, she screamed and moaned loudly while the fluids shot out and got all over her kitchen's floor, her senses overloaded and she fainted and lost consciousness.

Day 8

Vapor Trail regained her consciousness the next morning and groaned, she looked and saw herself urinating on the floor at regular speed, she finished and she panted from what happened last night. Vapor Trail did not have any energy in her hind legs and could not stand, so she flew around her home, she flew into a chair and sat, she clutched her groin since it was still throbbing, she sighed and began regaining her energy, she recovered and sighed, she got ready to go take a shower but the tentacle and worm took control of her,

"N... no." Vapor Trail said, and they made her fly out of her home. Vapor Trail flew to the Wonderbolts Academy and she saw several Pegasi training,

"Is that Vapor Trail?" Angel Wings asked, the others looked and saw her coming. Vapor Trail fought to regain control of her body and she began chasing Soarin, the stallions flew down to the others, they watched Vapor Trail as she moaned and grunted when she landed,

"WHAT ARE YOU DOING HERE, VAPOR TRAIL?!" Spitfire asked, Vapor Trail continued to moan and grunt, she managed to regain control of herself slightly, she grabbed the contact lenses in her eyes with her wings and took them out, they saw Vapor Trail's irises were red,

"Vapor Trail, why are your eyes red?" Sky Stinger asked, Vapor Trail reeled up on her hind legs and moaned in pain, the tentacle and worm came out of her groin region, the mares except for Rainbow Dash and Spitfire screamed while the stallions looked on with disbelief. The tentacle and worm took control of Vapor Trail and made her chase Silver Zoom and he flew around quickly, the tentacle drooled while it went after him, Vapor Trail grunted and the others noticed Vapor Trail fighting to regain control of her body,

"That thing's controlling her." Fleetfoot said,

"Come on, let's get that thing out." Rainbow Dash said, and they flew up to Vapor Trail. Silver Zoom flew as fast as he could while the tentacle and worm made Vapor Trail chase him, Spitfire flew to Vapor Trail and held her back from behind, Rainbow Dash, Angel Wings, and Sky Stinger grabbed the tentacle and worm, Vapor Trail grunted and threw her hind legs around,

"Hold still, Vapor Trail, let us get these things out." Rainbow Dash said, the slimy texture of the tentacle and the worm made it hard for the Wonderbolts to hold them, it slid through their grips and focused on Sky Stinger, the tentacle tried to pierce its tip into his mouth and he moved to the right to dodge it. Vapor Trail fought to regain control over her body while the tentacle and worm attacked the ponies on her, the worm tried to wrap around Rainbow Dash's neck to strangle her, she managed to restrain it by grabbing it with her wings, the tentacle then tried to go into Rainbow Dash's vagina,

"Oh no, you don't." Rainbow Dash said as she closed her hind legs as tightly as she could, the tentacle slid through her hind knees and made its way to her groin region, it rubbed its tip on Rainbow Dash's groin and she groaned uncomfortably. Angel Wings grabbed the tentacle and tried to pull it away from Rainbow Dash, the tentacle slithered through her grip and made its way into Angel Wings' vagina, she exclaimed loudly and the worm went into her urethra, other Wonderbolts flew over to try to pull Vapor Trail and Angel Wings apart. Angel Wings moaned and grunted as the tentacle and worm burrowed deeper into her orifices, she screamed when the tentacle's spines began to cut her vaginal walls from the ponies trying to get her and Vapor Trail separated from one another, Vapor Trail's eyes changed back to their regular color and she grabbed the tentacle and worm and tried to pull them out of Angel Wings' body, the Wonderbolts pulling on Angel Wings managed to pull her away and get the tentacle and worm out of her body, she clutched her groin and continued screaming since the tentacle's spines cut her vaginal walls and she was bleeding, the tentacle and worm took control of Vapor Trail again her eyes changed back to red, she flew around and threw the Wonderbolts away from her, they exclaimed as they fell, the tentacle and worm went back into her body and they made her fly away, Sky Stinger saw her flying away and chased after her.

Vapor Trail flew around and looked for a target, she saw an overweight stallion going into an apartment, she flew after him. Sky Stinger flew after Vapor Trail and saw her heading to the apartment, he flew down and went after her. Vapor Trail watched the stallion and flew into his apartment through the window, he opened the door and saw Vapor Trail looking at him with a warm smile on her face,

"Hello there, what brings you here?" the stallion asked, Vapor Trail flew to him while she tried to regain control of her body,

"You alright? What's with your eyes?" the stallion asked, Vapor Trail quickly knocked him down and she moaned and grunted as she tried to regain control of herself, she clutched her groin with her front hoofs as her eyes changed between the color red and her regular eye color. The stallion looked at Vapor Trail's groin and saw her vaginal fluids and urine dripping through her hoofs, Vapor Trail's eyes turned red and she held him down, the tentacle and worm came out and went into his mouth. The stallion gagged as the tentacle cut the roof of his mouth open and made its way into his brain, the veins reappeared on the tentacle and worm and Vapor Trail experienced another orgasm. Sky Stinger heard Vapor Trail and flew to where he heard her, he tackled the door open and saw the dead stallion and Vapor Trail, the tentacle and worm came out of the stallion's mouth and the tentacle had his brain in its mouth, Sky Stinger looked on with shock at what the tentacle was doing, he flew to Vapor Trail and tackled her down,

"Give me back my friend!" Sky Stinger said as he tried to grab the tentacle and worm, they tried to stab into his mouth and he ducked to dodge them, the tentacle then tried to stab its tip into Sky Stinger's chest and into his heart, he moved to his right to dodge the thrust. Vapor Trail flew to the corpse and the tentacle stabbed into his chest and took his heart, the tentacle ate it while Sky Stinger grabbed and restrained Vapor Trail from behind,

"First, my family needs help on things that are their own fault, and now, I come back and my best friend is controlled, I've had enough problems!" Sky Stinger said, the tentacle ate the heart and it and the worm went back into Vapor Trail's groin region. Vapor Trail's groin began to throb and make squishing noises, Vapor Trail exclaimed as she briefly regained control, but the tentacle and worm quickly retook control of her and threw Sky Stinger away, he grunted as he hit the wall, Vapor Trail quickly flew out of the window and went elsewhere while clutching her groin.

Vapor Trail flew while the tentacle and worm possessed her, they stopped and Vapor Trail grunted and clutched her groin as it throbbed painfully, she crashed and slid on the ground and grunted more. Vapor Trail rolled onto her back and turned a hundred eighty degrees while laying on the ground, she continued clutching her groin and she began screaming when she felt something growing out of her vaginal walls, blood began to fall out of her vaginal walls and sharp yellow teeth grew out, she continued to scream when blood began to come out of her clitoris, it split open vertically and a yellow eyeball was now in her clitoris, the skin in her groin region began to become scaled and changed to the colors dark pink and black. Vapor Trail continued to scream in pain and black claws grew out of her hoofs slowly while blood dripped. Vapor Trail's body began to change to the skin on her groin region and contort, her groin region became her new head, her front legs became her new legs, her hind legs became her arms, her wings grew bigger and came out of the creature's back, and Vapor Trail screamed as her face got sucked into the back of her new body and she completely disappeared. Vapor Trail lost complete control over herself and the tentacle and worm came out of the body's new mouths, it flew around and looked for mares, it flew around and saw a mare taking pictures of nature. The creature flew to her and tackled her down, the tentacle went into the mare's vagina and she screamed, the worm went into her urethra and the two throbbed as veins appeared on them, the mare moaned and grunted in pain while the tentacle and worm slithered into her orifices as slowly as they could, she moaned and soon lost her energy, the creature punched its right fist into her head and ripped her brain out, it then punched its left fist into her back and ripped her heart out, the tentacle and worm came out of her orifices and the tentacle ate her brain and heart, the creature flew up and looked for its next victim.

Sky Stinger saw the newly mutated Vapor Trail and stopped for a minute when he saw how much she has mutated, he quickly began flying after her and noticed Vapor Trail was a lot faster than before, he tried to catch up and she was going out of his sight. Sky Stinger heard the Sonic Rainboom behind him, he looked and saw Rainbow Dash flying after Vapor Trail, the other Wonderbolts were following her, Angel Wings was not present, he flew with them and went after Vapor Trail. Sky Stinger flew higher than the others and looked for Vapor Trail,

"She's over there." Sky Stinger said as he pointed to his left, he and the Wonderbolts flew in the direction, they saw Vapor Trail up ahead and she turned around and flapped her wings to create strong gusts of wind and it made the Wonderbolts get blown back, the exclaimed as they fell into the trees, Vapor Trail decided there were too many ponies and flew away to look for a pony who was by themselves for her to kill. Vapor Trail flew around and looked for ponies to kill, she saw none, so she flew down and began killing and eating small animals, the tentacle had drool fall out of its mouth every time it began chewing, it flew into the trees and flapped its wings around to create gusts of wind to make animals fall out of the trees. The animals fell out of the trees and Vapor Trail stabbed her claws into them to kill them and then began eating the animals, the bigger animals ran and flew away while Vapor Trail feasted on the ones she killed, the Wonderbolts caught up with her and Vapor Trail quickly turned around and flapped her wings around to create strong gusts of wind to push them back, they flew above and below the gusts of wind and they grabbed her. Sky Stinger flew and grabbed the tentacle and worm and tried to pull them out,

"Give me back my friend!" Sky Stinger said, Vapor Trail hit him away with the back of her right hand and Sky Stinger grunted as he hit a tree, Vapor Trail jumped and got ready to stab the claws of her right hand into him, Sky Stinger flew to his left and Vapor Trail stabbed and destroyed the tree. Sky Stinger flew to Vapor Trail and tried to get a hold of the tentacle and worm and strangle them, but they slid through his grip and he tried grabbing them with his wings, they still slid through and the worm tried to strangle him while the tentacle was about to stab its tip into his heart. Rainbow Dash hit the mutated Vapor Trail on the back of her head and it distracted the worm and tentacle, the other Wonderbolts gathered around and tried to pull the worm and tentacle out of Vapor Trail's body, she swung her arms around and some of the Wonderbolts got cut by her claws, they screamed as Vapor Trail flapped her wings and flew away. Sky Stinger and Rainbow Dash looked at the Wonderbolts who got hit, they all held onto their wounds and groaned,

"You all go along, I'll look after them." Spitfire said,

"By yourself?" Sky Stinger asked,

"No, I'll stay here and get them to the medics, too." Soarin replied,

"Alright, we'll look for her." Rainbow Dash said,

"Good luck, you two." Spitfire replied, and Sky Stinger and Rainbow Dash flew away.

Sky Stinger and Rainbow Dash flew up and looked for Vapor Trail,

"You see anything?" Rainbow Dash asked,

"No." Sky Stinger replied,

"Still, what is that thing in her?" Rainbow Dash asked,

"I don't know, but all that matters is we get it out of her." Sky Stinger replied,

"Truth be told, Sky Stinger, I think Vapor Trail's weird behavior change could be because of those things." Rainbow Dash said,

"Of course it is, I've known Vapor Trail for a long time, she would never act like that normally." Sky Stinger replied,

"Well, I'll go search for her, can you wait and scout here?" Rainbow Dash asked,

"Sure." Sky Stinger replied, and Rainbow Dash flew forward. Sky Stinger waited and fell asleep in a tree while he waited for Rainbow Dash to come back, he sprung awake when he heard loud animal noises to his left, it was dark and Rainbow Dash was nowhere to be seen, he looked and saw Vapor Trail killing and eating more animals,

"Vapor Trail!" Sky Stinger said as he flew to her, Vapor Trail saw him coming and she flew up to him at high speeds and tackled him. Sky Stinger grunted but he managed to recompose himself and Vapor Trail was holding him down as she flew up, the tentacle got ready to try to stab him in his forehead and Sky Stinger moved his head down to dodge it, Sky Stinger grunted as he wrestled with Vapor Trail's arms with his front legs, he tried kicking Vapor Trail in her thighs with his hind legs and it had no effect, the tentacle tried to stab him again but Sky Stinger opened his mouth and bit down on the tentacle as hard as it could, Vapor Trail roared in pain and flew around while trying to get Sky Stinger's teeth off of the tentacle, the worm tried to wrap itself around Sky Stinger's neck and strangle him again, he grabbed it as tightly as he could and held it back. Vapor Trail flew around erratically while trying to get Sky Stinger's teeth off of the tentacle, she grabbed the tentacle and tried to pull it out of Sky Stinger's mouth, but he bit down on it harder. Vapor Trail flew around more erratically while she roared in pain, Sky Stinger saw Vapor Trail flying up near to a rainbow factory above them and she hit Sky Stinger on it, he grunted and stopped biting down on the tentacle, he heard electricity crackling and Vapor Trail about to stab him with her claws, she stabbed the claws on her right hand forward and Sky Stinger ducked to dodge it, she stabbed into the factory and Sky Stinger flew away as quickly as he could, the factory exploded and Sky Stinger screamed as the shock wave made him spiral out of control and fall.

Sky Stinger fell onto the ground and rubbed his own tongue with his front hoofs since the tentacle tasted bad, fire appeared everywhere in the forest and he looked around and saw the destroyed factory in the sky, he heard a thud and saw Vapor Trail land on the ground, she was on fire, she stood up straight and roared while holding her arms out, she then began flying towards Sky Stinger in an attempt to ram him into the fire, Sky Stinger flew to his right and Vapor Trail stopped flying and faced him, she lunged forward and tried to slash him with both of her claws, Sky Stinger flew back to dodge it. The tentacle slid out of Vapor Trail's mouth and tried to stab Sky Stinger, he bent down backwards to dodge the lunge and grabbed the tentacle, he exclaimed with the tentacle's spines cut his left shoulder, the tentacle slid through his grip and opened its tip into four sections, Sky Stinger saw the tentacle had many rows of teeth in its mouth, like a shark. The tentacle lunged down and tried to bite his head, Sky Stinger let go of the tentacle and flew away while the tentacle dived its mouth into the ground, it came out and flew after him. Sky Stinger looked for something to jam the tentacle's mouth with, he saw a stick and picked it up, Vapor Trail flapped her wings around to create gusts of wind in an attempt to knock Sky Stinger down, he grunted as the gusts of wind from her wings pushed him back, he looked back and saw fire behind him, he tried to fly to his left and Vapor Trail flew to him quickly and tried to slash him with the claws on her right hand, he moved back but exhaled when the tip cut his left chest a little. The tentacle came out again and tried to stab its tip into Sky Stinger, he lodged the stick into the tentacle's mouth and the four mouths closed on it and destroyed the stick, his eyes widened a little and he looked for something else to jam the tentacle's mouth with. The worm slithered out and wrapped itself around Sky Stinger's neck, he gagged and tried to get it off while it pulled him towards Vapor Trail, she got ready to stab her claws into him and kill him while Sky Stinger stopped trying to get the worm off and looked for something to use as a weapon. Sky Stinger grabbed the ground in hopes of using something, he got a long stick and waited as the worm dragged him forward, it stopped and Vapor Trail began to stab her claws down, Sky Stinger stabbed the long stick into the eye and Vapor Trail screeched as she covered her eye. Sky Stinger grabbed the worm and dragged it near the fire, it struggled and Sky Stinger got a rock and put it on the worm, he then got another stick and put it in the fire, he put the fire on the tip of the worm and it began to burn, Vapor Trail screeched as the worm caught on fire, it burned and soon died and left a patch of grass on fire. Sky Stinger saw Vapor Trail was now blind and the worm was dangling out of the orifice, the tentacle lunged towards Sky Stinger and he flew above it, the tentacle went up and tried to stab its tip into his scrotum in an attempt to cut them open, he quickly covered his groin with his front hoofs and he yelled in pain when the tentacle cut his front hoofs. The tentacle moved its tip out of his front hoofs and got ready to attack again, Sky Stinger saw a rock and went to it while the tentacle slithered out but could not reach him, so Vapor Trail flew to him and flapped its wings in an attempt to make the wind mess up his flight. Sky Stinger got the rock and flew to Vapor Trail, the tentacle opened its mouth again and it got ready to eat his brain, Sky Stinger shoved his right front hoof down the tentacle and shoved the rock in, the tentacle gagged and fell to the ground and struggled to breathe, Sky Stinger landed and slammed his hoofs down onto the tentacle, he winced in pain when the spines cut his hoofs, the tentacle gagged and struggled to breathe. Vapor Trail swung her arms around erratically and the tentacle wheezed, Vapor Trail soon stopped moving and the tentacle drew out its last breath and died.

Vapor Trail fell over and she began to revert back to normal, her entire body changed back to normal and she panted, the worm was hanging out of her urethra and the tentacle hung out of her vagina. Sky Stinger flew to her while Vapor Trail panted and looked at the worm and tentacle,

"Vapor Trail." Sky Stinger said, she looked at him,

"Sky Stinger?" Vapor Trail asked, she began to cry and she and Sky Stinger hugged one another,

"I'm sorry, I completely lost control of myself and my mind, the creatures took over me completely." Vapor Trail said, and they stopped hugging one another,

"Alright, let's get these out of your body." Sky Stinger said,

"No, wait, Sky Stinger, I need them for tomorrow, just take me home for now, I don't have any energy to move right now." Vapor Trail replied, and Sky Stinger carried her and flew home and they slept together.

Day 9

Vapor Trail dreamed about flying on a clear day and flew through a field of grass, she woke up in her bed and saw Sky Stinger sitting across from her,

"You okay?" Sky Stinger asked,

"Yeah, I need the family and relatives of those dead ponies to be contacted." Vapor Trail replied,

"Stay here, I'll track them down." Sky Stinger said,

"Okay, I'll go get my doctor." Vapor Trail replied,

"No, you need to rest." Sky Stinger said,

"It's a short trip, Sky Stinger, I can make it." Vapor Trail replied, and the two flew out. Vapor Trail covered her groin with her front hoofs and hid the worm and tentacle, she waited for her doctor to finish and she told him she needed him at her home and to bring the book about the incubus with him, they waited and Sky Stinger arrived with the relatives of the ponies she killed,

"Thank you all for coming, I know what happened to your dead relatives." Vapor Trail said,

"You do?" a stallion asked,

"Yes, truth be told, a creature that invaded my body took control of me and made me kill them." Vapor Trail replied, and she showed the tentacle and worm dangling out of her vagina and urethra,

"What? That is the most ridiculous..." a mare said,

"She's telling the truth." the doctor said, the ponies exclaimed in confusion,

"This creature is called an incubus, I have the information on it here." the doctor said, and he showed them the page in his book on it,

"So, this thing made you kill our relatives?" another stallion asked,

"Yes, I'm sorry, I really am, I wasn't in control of myself, I tried to fight and regain control of my body, but I couldn't." Vapor Trail replied as she began to tear up, she began to cry a little,

"I was away when the creature entered her body, I didn't know until yesterday." Sky Stinger said,

"I tried to pull it out when I saw it, but it fought back and went back into her body." the doctor said,

"I see, well, at least you all tried to help." another mare said,

"I'll take any punishment you all want to give me." Vapor Trail said, the ponies thought and talked about what to do,

"We're not pressing charges." the first mare said,

"What?" Vapor Trail asked as she looked at them,

"You said it yourself, you weren't yourself, and you tried to resist, it's not your fault." the first stallion replied, the other ponies nodded, Vapor Trail just looked at them,

"Thank you." Vapor Trail said a few seconds later,

"You're welcome, and thank you for letting us know what happened, try to take it easy." the second mare replied, and they left,

"Well, let's get them out of your body." the doctor said, and he pulled the tentacle and worm out of Vapor Trail's orifices and she let out a short moan,

"Okay, it's out." the doctor said,

"Thank you." Vapor Trail replied,

"Well, I'll be going now, take care." the doctor said, and he left. Vapor Trail tried to get on with her day but she yelped and clutched her groin,

"Vapor Trail?" Sky Stinger asked as he ran to her, he looked and saw urine falling through Vapor Trail's hoofs,

"Oh, you just had an accident." Sky Stinger said,

"No, take me to the doctor, I don't feel right." Vapor Trail replied,

"Let's wait first and see if it happens again." Sky Stinger said, and Vapor Trail tried to get on with her day again but stopped and clutched her groin again, she exclaimed as she urinated again,

"Come on, Vapor Trail." Sky Stinger said, and he got ready to carry her, Vapor Trail began struggling,

"What's wrong?" Sky Stinger asked,

"I'm not comfortable being touched right now." Vapor Trail replied,

"Oh, well, that would make sense, I mean, you did have a creature inside your private parts." Sky Stinger said,

"Come on, Sky Stinger, let's go to the doctor." Vapor Trail said, and they flew to the doctor.

Vapor Trail sat and waited with Sky Stinger, she clutched her groin and she urinated a few times while waiting, the doctor came out of his work room,

"Vapor Trail." the doctor said, and she and Sky Stinger entered,

"What is the problem now?" the doctor asked, Vapor Trail blushed deeply,

"She's peeing at random times." Sky Stinger said, Vapor Trail urinated again,

"I think I know what's going on, since the incubus controls the body systems of the orifice it enters, Vapor Trail probably lost control of her bladder, she's just going to have to retrain herself like how she did when she was a kid, I have diapers for the situation." the doctor replied, Vapor Trail thought about wearing diapers in public and blushed with embarrassment,

"Um, can we skip the diapers?" Vapor Trail asked,

"That's fine, most ponies do, I have a bottle as an alternative." the doctor replied,

"I'll take that." Vapor Trail said,

"Yeah, I think Vapor Trail will be embarrassed wearing a diaper in public." Sky Stinger said,

"Okay, here you go." the doctor said as he got the bottle, Sky Stinger took it,

"Thank you." Vapor Trail said,

"You're welcome, go on now." the doctor replied, and the two left.

Sky Stinger and Vapor Trail went back to Vapor Trail's home and Vapor Trail laid in bed while Sky Stinger fed her breakfast,

"Thank you, Sky Stinger, I think I'm going to lay in bed for now." Vapor Trail said,

"Go ahead, take a break, Vapor Trail." Sky Stinger replied,

"I'm still upset over myself, I couldn't resist the incubus' control." Vapor Trail said,

"Well, try not to overthink it, you weren't yourself." Sky Stinger replied,

"No, what I mean is every time I got controlled, I was fighting with my mind to regain control over my body, but I couldn't." Vapor Trail said,

"Why didn't you say anything about it?" Sky Stinger asked,

"The creature would've took control of me to make me silent." Vapor Trail replied,

"Oh, no wonder why, well, go ahead and eat, Vapor Trail." Sky Stinger said, and he fed her fruitcake with a spoon and she ate it, she then clutched her groin with her front hoofs and wings,

"Sky Stinger, I'm about to pee." Vapor Trail said,

"Hold on." Sky Stinger said, and he put the bottle against her groin and Vapor Trail held it in place and urinated into the bottle,

"Can you not look, Sky Stinger?" Vapor Trail asked as she blushed,

"Come on, Vapor Trail, I'm your best friend." Sky Stinger replied,

"I know, but you're a boy and I'm a girl, I'm just not comfortable with that." Vapor Trail said,

"Well, you'll just have to get used to it, there's nopony else available right now." Sky Stinger replied, Vapor Trail sighed and finished urinating,

"Here." Vapor Trail said as she gave the bottle to Sky Stinger, he went to the bathroom and dumped her urine into the toilet and flushed it, he went back and looked at the time,

"Come on, Vapor Trail, it's time for Wonderbolts training." Sky Stinger said, and Vapor Trail stood up and flew out of bed while Sky Stinger touched her shoulder and abdomen, she winced,

"Oh, right, sorry, let's go." Sky Stinger said, and they flew to the Wonderbolts Academy.

Sky Stinger and Vapor Trail arrived at the Wonderbolts Academy and Sky Stinger informed everypony about Vapor Trail's condition, she sat out and watched the Wonderbolts train, Angel Wings was with her and clutching her groin,

"I'm very sorry about yesterday, Angel Wings." Vapor Trail said,

"It's okay." Angel Wings replied,

"How are you holding up?" Vapor Trail asked,

"I'm fine, I'll need to get surgery on my girl parts, though." Angel Wings replied,

"You're not hurt, are you?" Vapor Trail asked,

"Not anymore." Angel Wings replied,

"Good, might as well enjoy the show then." Vapor Trail said, and they watched the Wonderbolts. Vapor Trail watched and urinated into her bottle every once in a while, she watched Angel Wings and saw her smiling as she watched, they finished and Spitfire flew down and walked to Vapor Trail,

"Were you being controlled by that thing every time you caused trouble?" Spitfire asked,

"Yes." Vapor Trail replied as she looked down,

"I see, I apologize for getting angry at you, you're welcome to rejoin when you recover." Spitfire said,

"Thank you." Vapor Trail said,

"Take it easy, Vapor Trail, you can come back anytime." Spitfire said, and she flew away. Vapor Trail looked and saw Sky Stinger with Rainbow Dash,

"Where were you when we were searching for Vapor Trail?" Sky Stinger asked,

"Sorry, I kind of got carried away." Rainbow Dash replied,

"What do you mean you got carried away?" Sky Stinger asked,

"I got hungry, so I went to a restaurant, I then got tired, and fell asleep." Rainbow Dash replied, Sky Stinger glared at her while Rainbow Dash smiled sheepishly,

"Are you serious?" Sky Stinger asked,

"Yeah, sorry." Rainbow Dash replied,

"You better be, because I had to fight Vapor Trail to get her back." Sky Stinger said, and they went back to doing more Wonderbolts training. Vapor Trail sat at lunch and she was actually hungry for once, she ate the vegetables and drank the water, she had a little trouble swallowing,

"You okay?" Sky Stinger asked,

"Yeah, it just tastes strange after not having it for some time." Vapor Trail replied, and she ate, she felt herself about to urinate again,

"Excuse me a minute." Vapor Trail said, and she clutched her groin and flew to the mares' bathroom, she came back and had lunch again, she watched the Wonderbolts train more after lunch and went home with Sky Stinger after the day was done.

Vapor Trail laid in bed again and Sky Stinger fed her a salad,

"How are you feeling?" Sky Stinger asked,

"I'm still a little tired." Vapor Trail replied, knocking was heard at the door,

"Vapor Trail? You there?" Rainbow Dash asked,

"Come in." Vapor Trail said, the door opened and they heard running, they saw Rainbow Dash fly into the room and Twilight Sparkle ran,

"Oh, hello." Vapor Trail said,

"I heard about what happened, you okay?" Twilight Sparkle asked,

"Yes, I'm fine right now, I lost control of my bladder, though." Vapor Trail replied,

"I'm glad you're okay, I tried to go through my books on the incubus, I didn't know those things were still around." Twilight Sparkle said,

"You know them?" Vapor Trail asked,

"I only read about them, Princess Celestia's looking for the remaining incubi and succbi right now." Twilight Sparkle said,

"Still, having that thing in your crotch must've hurt." Rainbow Dash said,

"It did." Vapor Trail replied,

"Well, it's good it's out, I'm going to use my magic to help Princess Celestia find the rest, Rarity's helping, too." Twilight Sparkle said,

"Wait, Rarity's looking for them?" Sky Stinger asked,

"Yeah, she's looking for the incubi, too, she's been calling them 'repulsive creatures' for some strange reason, though." Rainbow Dash replied,

"Well, good luck to you two." Vapor Trail said,

"Thank you, we're just here to make sure you're okay, bye, Vapor Trail." Twilight Sparkle said,

"Bye." Vapor Trail replied, and Twilight Sparkle and Rainbow Dash left. Vapor Trail ate more and urinated into the bottle several times while Sky Stinger looked after her, she finished dinner for the day and she and Sky Stinger fell asleep. Vapor Trail dreamed about the tentacle and the worm rubbing themselves on her clitoris, Vapor Trail woke up while screaming and quickly covered her groin, Sky Stinger quickly came into her room,

"You okay, Vapor Trail?" Sky Stinger asked, she panted while tears rolled down her cheeks, she looked at her groin and saw nothing,

"I had a bad dream that the incubus was still in my body." Vapor Trail said,

"Come on, Vapor Trail, it's just a bad dream, lay back down." Sky Stinger said, and he put her down and she winced when he touched her, he put her blanket over her and flew out of the room. Vapor Trail dreamed about herself killing ponies and animals and eating the dead animals, she woke up again and had a headache, she groaned and passed out without dreaming again for the rest of the night.

Day 10

Morning came and Vapor Trail groaned as she woke up,

"You alright, Vapor Trail?" Sky Stinger asked,

"I had another bad dream after falling asleep again." Vapor Trail replied,

"How are you feeling right now?" Sky Stinger asked,

"Terrible." Vapor Trail replied,

"Can you move?" Sky Stinger asked,

"I just want to lay down all day right now." Vapor Trail replied,

"You hungry?" Sky Stinger asked,

"No." Vapor Trail replied,

"Before I leave, let's try something, try touching me, Vapor Trail, let's see if you can handle it." Sky Stinger said, and he held his left front leg out, Vapor Trail tried touching his leg but winced and pulled her hoof away when she did,

"Wow, so you're scared of touching others, too." Sky Stinger said,

"It would seem so." Vapor Trail said,

"Well, I'll go do my Wonderbolts training now, I'll be back." Sky Stinger said,

"Okay, good luck." Vapor Trail said, and Sky Stinger left. Vapor Trail flew out of bed and went to her bathroom, she looked at the shower and memories of the tentacle rubbing its tip on her clitoris and sucking it flooded her mind, she looked away and closed her eyes, she flew to her kitchen next and memories of the tentacle making her drink her own urine and the night when the tentacle and the worm overloaded her senses, she looked at the floor and saw Sky Stinger has cleaned her body fluids off, the memories continued to flood her mind and she looked away while closing her eyes again, she felt her bladder about to leak again and flew to the bathroom. Vapor Trail laid back in bed and did nothing, memories of the tentacle rubbing itself on her clitoris when she tried to sleep one night flashed in her mind, it stopped when she heard the door open,

"Vapor Trail, I'm home." Sky Stinger said, he flew into the bedroom and saw Vapor Trail looking at the ceiling,

"Vapor Trail?" Sky Stinger asked, Vapor Trail did not respond while the memories flooded her mind, he touched her hoof and she winced and snapped back into reality,

"What's wrong, Vapor Trail?" Sky Stinger asked,

"I've been remembering my time when under the incubus' control, but whenever I look at where it took control of me, memories flood my mind, and I can't bear to look at the places where it happened." Vapor Trail replied, Sky Stinger's eyes widened as he realized what was happening,

"Wait here, I'll be back." Sky Stinger said, and he flew out again. Vapor Trail stared at the ceiling her memories flooded her mind, she tried to sleep but she dreamed of the tentacle and the worm entering her vagina and urethra, she sprung awake and screamed as she covered her groin, she panted and saw it was still afternoon, she heard the door open and Sky Stinger entered,

"Okay, sorry I took so long, but Starlight Glimmer is willing to counsel you, come on, Vapor Trail, this way." Sky Stinger said, and Vapor Trail took her urine bottle and flew.

Vapor Trail sat outside of Starlight Glimmer's office at the School of Friendship and breathed nervously,

"There, take a deep breath and relax, Vapor Trail, just tell Starlight Glimmer what's been bothering you." Sky Stinger said, the door opened and a student left,

"There, that's all the students for today, come on in, Vapor Trail." Starlight Glimmer said, and she and Sky Stinger entered her office while Starlight Glimmer closed the door and Vapor Trail begun her therapy.
