Incubus

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.
