Entry 3 – Incubus

<><><><><><><>

Kayden gripped his sister by her new wings, admiring her ass for a moment before he plunged himself into her cunt, filling her with his cock once more. Jenny moaned into the pillow, the feathery cushion barely doing a thing to muffle her wanton wails as he kept fucking her. He couldn’t help but smile as he felt better than he had in a while, like his sickness was disappearing with every thrust, every jolt of pleasure that rode through him. It was intoxicating, to drive his cock into Jenny like she was some village girl rather than his wonderful younger sister. It had seemed wrong at first, when she was over him, he’d been overtaken by panic, then she kissed him, and his mind had filled with a dense fog. Kayden shook his head at the silly notion, why should them being brother and sister come between love, especially when it felt this good? 

Jenny was legitimately the best lay he’d ever had in his life. Her pussy brought Kayden in, caressing him in ways he’d never felt before. When she came, it was like her snatch was trying to milk him of his very soul, massaging him and yet also opening up in a way which boggled the mind. Even as he fucked her, he didn’t even start to feel tired, merely more and more re-invigorated as he just kept fucking her, filling her with his seed like she deserved. She’d woken up something in him, a great beast which which desired his darling little sister. 

Letting go of his sister’s new wings, he raised his hands and slapped them down on his sister’s wonderfully full and round ass, listening to her squeal as he did so. Kayden grinned savagely as he gripped that ass, continuing to slam his dick the little slut, feeling himself getting closer and closer to cumming in her again. He’d already cum enough that when he pulled back, his cum dripped out from her hole onto the sheets.

While he played with her ass, spreading it out, watching as her back hole twitched with every thrust, Kayden got a wicked idea. He pulled out of Jenny, his cock lubed up by the solution made of his cum and Jenny’s. As he pulled out, his sister gave a needy whine, sounding like he had back when Dad had one time had to punish her and took her favourite toy away. Kayden gave a single note chuckle before he spread her ass even further, and pushed her down further into the bed, before sliding his cock into her back hole. Jenny gasped in surprise, and she sprung up from the pillow, looking back at him, with confusion, but not hurt. As she did so, Kayden continued to push forth, and then hilted himself into Jenny. His sister let out another moan as her eyes crossed, and her tail curled up like a pigs while her wings pulled in. Kayden moved his hands to grip her hips, before he began to slowly thrust in and out, listening to those sweet, sweet moans as Jenny learned a new way of gaining pleasure as her ass was spread around his cock. 

“Please brother, h-harder, f-fuck me hard-harder!” she cried out, forcing that last part out of her as Kayden grinned, that fire in him stoked. Gripping down hard, he pulled out of her until only the tip was in, before violently pulling his slutty sister towards him, hilting once more in a single swift move. She cried out like a stuck pig, her squeal filling the house and likely going beyond, though it wasn’t of pain, but of mind numbing pleasure.

Then he did it again, and again, and again, roughly fucking his sister with long, brutal strokes, filling her completely. All the while his ever heavier growing balls smacked at her pussy, leaving it quivering as it practically begged for more. But she’d already been violated there, and he wanted to take everything of hers, stealing away all of her firsts. Every time he pulled out, and thrust back into her, she moaned as pleasure rocketed through his cock and filled him. Her ass was just as good as her pussy, squeezing around him, undulated as it did it’s best to pleasure him, giving him a nice tight hole to fuck as it tried to milk him of his cum. Jenny’s arms quickly weakened as he kept going, and she slammed into the pillow again, her tail going out straight and her wings opening up as her ass started to practically jerk him off itself while he fucked her. Kayden felt something spray against his legs and grinned as she came again because of him. He was starting to feel that edge himself. He already knew it was too late, so he redoubled his grip once more, and started to speed up even faster, not caring to pull the whole way out, but rather just giving quick heavy thrusts into her full ass, and feeling his pleasure explode. He knew he was starting to cum again, but he kept going for a few moments, fucking through his cumming, giving the smallest of moans as he kept going until it was too much. He started to shoot his cum into her ass, before eventually he stopped, enjoying the sublime bliss of cumming in his sister’s tight back hole.

They stayed like that, frozen until Kayden pushed Jenny away from himself into the pillow. Jenny made a surprised noise as the lesser succubus pushed herself up, while Kayden dropped back into a sitting position, his cock still standing tall and hard, raring to go again. Tilting his head, and then pointing his hand to his cock, he only said two words.

“Clean it,” and he could see it already affecting Jenny. She blushed hard, her breath speeding up again, and she licked her lips. At the same time, her wings twitched and her tail curled before she crawled to him on all fours. By the time she reached him, she looked practically out of breath even from that small journey across his bed, though Kayden knew it was from arousal. Jenny didn’t even hesitate as she dove head first into his crotch, her mouth open wide as she started to suck his cock, filling her mouth with his girth. She started to bob her head while her tongue moved around his dick, sending wondrous sensations through Kayden as Jenny sucked him off. Kayden himself leaned back and smiled to the Heavens, enjoying how his slutty sister was tending to his cock, fondling his balls while cleaning him of their juices. He placed a hand on her head, and pushed her all the way down until he could feel his cock in her throat, though she didn’t gag or sputter at all.

What a lovely, slutty sister I have here. He thought as he looked back at her, and saw her gazing up at him from his cock, her nose being tickled by his bush, and he couldn’t help but give her a loving smile.

After all, what else are slutty sisters like this for anyways?
