Cursed siblings (Tenty x Skeith Takahata II)

[Tentacle_Lover]

It was shortly after Alison's 17th birthday, about a week infact, and she was laying up in her room with a book held up over her head, the curtains still wide open despite the fact it was the dead of night outside. It was a nice night, stars in the sky, so Alison decided to leave it in view. She wasn't sure why, she just felt like it really. Turning the last page of the book and spending a few minutes reading it, Alison sighed slightly, then snapped the book shut, tossing it casually onto the bedside table beside her. "It started out so good too....then it just went all predictable towards the end..." She sighed and grumbled, swinging her legs around off the bed and standing up, tugging at her bra slightly as she glanced down at herself, wearing only her underwear. "Geez...am I getting bigger again? I hate going bra shopping....the lady at the store who does the fitting is always so creepy....I swear she just likes copping a feel..." She grumbled again, walking over to the window and slowly looking up at the sky, though suddenly, when her eyes fixed on a very prominent feature in the night sky, her entire body froze.

Alison's gaze was transfixed....simply staring at the full moon hanging in the sky...so big tonight...so bright...she couldn't look away. For almost a solid minute Alison just stared in silence, then gasped as she suddenly felt a heat flooding through her body, then winced when she felt a rather sudden tightness. "HNGH!" She stumbled away from the window, clutching at her stomach at first, but then the tightness spread, moving lower between her legs, then shifted into a burning heat. "AH!" With a loud, sensual cry Alison fell backover onto her bed, her panties suddenly growing dark with heat and moisture, an arousal more incredible than anything she had ever felt before overtaking Alison's body. Within moments her nipples were hard, poking through her bra. "O-oh god...!" Alison shook her head quickly, then cried out, grasping at her bedsheets tightly and arching her back as the tightness from before returned.

This time it didn't go away however, it just got worse and worse, almost painful, like something inside of her was desperately trying to get out of her. "Nnn...ahh...." Alison moaned, cried out in pain, growled, then went back to moaning again as the sensations flooding her body continually shifted....until she felt it, like a dam bursting. The tightness suddenly seemed to release, or more accurately, it shifted rather considerably. It felt like something had just burst out of her, like a great pressure inside of her body was released....but Alison quickly realised that there was a very different tightness in its place. As she slowly looked down, Alison gasped at what she saw, a large, throbbing bulge in her panties, which were slowly peeling back, causing friction against whatever was in her panties, and sending intense shivers of pleasure throughout the girls body.

"Wh-what....what is..." Alison was slowly reaching towards her panties, but before she could touch them the material slipped down, allowing a huge erection to spring free, pre-cum flicking over chest. "Oh god....wh-what....ooooh!" Alison didn't have time to wonder what was happening, instead an intense arousal flooded her body once again. She had to satisfy herself...nothing else mattered. Alison's hands quickly went to work, grasping her newly grown cock and starting to pump it, the girl grunting like an animal with every single thrust, but no matter how hard or fast she pumped it, she felt no closer to release...and the longer she went without release, the greater the need to find that release became. "Not....not enough..." Slowly Alison began to get back to her feet. "Hands...not enough..." She needed more....her own hands wouldn't bring her the release her body wanted...no...that her body needed...she could already feel the arousal growing, her rational mind starting to give way to it. With another deep growl, the girl turned towards the door....desperate to find a suitable hole for her cock to find its release...

 

[Skeith Takahata II]

It had been about six years since Jack had disappeared. She was believed to be dead, and she liked it that way. She was dangerous, and didn't want to hurt anyone, especially her precious younger sister. She would have been only about 11 years old when they last saw one another. Since her first full moon, Jack had been watching over her sister from a distance, watching her for any sign of a change, the same change that had befallen her. She could only pray that she didn't inherit the same damned curse that had claimed her.

She'd hurt her best friend that night. She'd left her broken and numb, nearly catatonic. She knew the kind of harm her younger sister could do if she wasn't constantly observed, or at least not sated on her first full moon. Fortunately, Jack's endurance had grown greatly at the time of her transformation. She could take the abuse if need be. She stood on a roof across the street, looming in the shadows, watching her sister through her window. Fortunately she'd left the curtains open. "Hi Ali..." She whispered quietly as she watched her, reading her book. "Happy birthday, kiddo." It had been painful watching her little sister grow up, and not being involved. Her said smile broke when she saw Alison fall back onto her bed holding her stomach. "No... It can't be..." She leaped to the grass below and began running across the street. Someone was going to get hurt if she didn't hurry.

The moon was effecting her too, but she had learned to control it. It was always easier after the first night. She could feel an arousal inside of her, but it was in check. She leaped to the window of her sister's room, breaking through the glass with ease. She tumbled into a kneeling position in the center of the room. "Alison!" She shouted, standing up slowly. She braced herself for the worst, parting her legs for better balance, as she opened her hands, assuming a readied stance. She lowered her gaze to look at the throbbing shaft that twitched between her legs. "Not you too..." She whispered in disbelief.
