Fandom: Legend of Korra/potential crossovers. Story idea: Amazon Korra-from Adventures of the Last Amazon-must now handle the Incubi as well. Contains: Futa on male, anal.
Korra knew something was wrong the moment she woke up. Asami always woke up before her, and always woke Korra with attention to her morning stiffness in some way or another, be it gently with her hand, skillfully with her mouth, or with a passionate riding. To wake up with her morning wood still present and throbbing painfully for attention meant that something urgent was keeping Asami away.
Korra jumped out of bed, opening the door and going into the hall. Sure enough, Korra could hear the sounds of a struggle happening from the down the hall, and ran down it to find Asami locked in a struggle.. against Kai? He was a bit of a jerk now and then sure, but Korra couldn't think why he was attacking her, pulling at her clothes and all but hissing like an animal, only held back because Asami was stronger and more skilled than him.
Then she sensed it, an energy she hadn't felt in almost two years now. It was flowing from Kai. 'Succubus energy,' Korra thought, growing nervous, 'No.. incubus energy.' he corrected herself as she ran over and pulled Kai off of Asami, throwing him to the ground and keeping him bound there with stone. Korra explained what she'd felt, and Asami stared in shock.
"I didn't there were any incubi." Asami said. "There weren't," Korra said, "The Succubi were an all female race, they didn't have sons and couldn't infect males with their energy. I doubt Boa and Robin have anything to do with it this time, they're still trapped in that other dimension, boning each other senseless. Whatever did this to Kai, and probably other males in town or even in the fandom-verse, this is something else, someone else."
"You're gonna have to deal with them again, aren't you?" Asami said, not liking the answer that they both already knew. She nodded, "Yes. I don't know where this started, but it could end with incubi taking over the fandom-verse if I don't do something." "Well.. then I'm coming with you this time." Asami said, "I can fight, I've got weapons, and I can help you sate them." Korra shook her head, "If you tried, their energy would infect you. I refuse to let that happen after everything I did to save you from this last time."
"Stay here, warn the others, fight off or capture any incubi that show up. I'll have to sate them myself." Korra said. "Go warn Lin about this and have her sent out a patrol, I'll cure Kai and meet you at the fandom-verse terminal." "..Alright." Asami said after a moment of hesitation. She hated it, but she knew Korra was right. She gave her a kiss, then left the house.
Kai meanwhile was still struggling and failing to free himself from the earthen bindings holding him in place. Korra undressed him easily, moving the stone shackles to hold his legs apart. She could sense his true desire, his want for submission during sex. Korra knew she could probably cure him faster if she brought Jinora in and had her ride and dominate him while she took his hole, but Korra didn't want it to go quick. She was frustrated that this was happening again, and wanted to take her time taking it out on Kai.
She removed her pants, water bending some liquid from the kitchen to lubricate her twelve inch stiffness before lining it up to Kai's virgin rear, giving him no warning before she thrust forward, penetrating deep inside him with her strength and making his own cock pulse with desire. He groaned in a mix of pain and pleasure as Korra pulled all the way out before thrusting in even harder, smacking Kai's cock to elicit more moans from him and make him clench around her tighter.
Korra moaned as she thrust through the tightness. This might be a slog, but at least since Asami wouldn't be in danger, she could really enjoy herself this time.
For the record, I wouldn't mind one where instead of this I continue with the story as it was, with all females, but adding the fandoms I hadn't been in originally (Miss Kobyashi's Dragon Maid, Star vs the Forces of Evil, Shimoneta, Homestuck, etc).
