Incubus

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.
