Incubus

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.
