Tahla's Halloween
"You sure you'll be okay by yourselves?" Erin asked, a note of concern in the glaceon's voice. 
"I'll be fine, Mom." Tahla said exasperated, for what felt like the hundredth time. 
Erin sighed and pulled her daughter into a hug, nuzzling between her ears. "This'll be first time your father and I will be away more than a night since you kids were born. You can’t blame me for worrying." 
Erin spotted her son trying to sneak by and grabbed him for a hug as well. 
"Geez, Mom!" Telain said as he weakly hugged her back. "You're only leaving for the weekend. Not even 3 days." 
 "I know, I know." Erin sighed as she released the twins. "You have our phone numbers if you need anything and I told your aunt in case you can't reach  us." 
"Okay, the car's all ready." Jamie said, as the older flareon came in the front door. "Stop pestering the kids and grab your bags, hun."   

Tahla waved at her parents as they pulled out of the driveway. She grinned, giddy with excitement. Now she just had to wait for her brother to leave and she'd have the house all to herself. 
It wasn't long before he poked his head in her room with a bag slung over his shoulder. "Hey, sis, I'm headed out." 
"I'll get the door." Tahla hopped up and locked the door behind him. She watched him out the window and as soon as he was out of sight, she ran to her room and practically dove under her bed. Toys and stuffed animals flew out behind her as she dug deeper, she squealed triumphantly as she emerged with a large leather-bound book and tossed it on the bed.
She jumped onto the bed and sat next to the old book. She fixed her skirt then slowly opened the tome. The eevee girl flipped through the pages, quietly reading the titles.
“Hm… riches, teleportation, invisibility…” Her face twisted in concentration as she flipped through the pages faster. “Here it is!” She shifted in her seat and smoothed out the page labeled Seeking Love, her fingers slowly tracing the word as she considered it’s implications. She read down the page, looking for where to start, then she took a deep breath and began reading the passage aloud. Her tail twitched in equal parts nervousness and excitement as she spoke the alien words. 
As Tahla finished reading the incantation and the words faded into the silence of the house, she held her breath with anticipation. Her mind raced as she waited, searching for any indication that the spell worked. Her lungs began to burn, and she gasped as they reminded her to breathe. She sighed and laid back, pushing the book down the bed with her feet.
“Well now I just feel silly,” she said as she yawned, exhausted, all her energy suddenly gone after waiting all day and trying to hide her excitement while the house slowly emptied. She smiled, watching the bright moonlight dance on her ceiling as she drifted off to sleep.

Tahla’s breath caught in her throat as she awoke to an intense chill running up her leg. She sat up and a scream caught in her throat as she looked at a translucent, grey… tentacle rose up at the end of her bed. She threw herself towards the door, meaning to run away, but she was caught in the air, the chill on her leg returning more intensely as the tentacle grabbed her. It held her aloft, hanging upside-down. It’s cold slime dripped onto her fur, sending a chill up her spine. She thrashed around, trying to break free from it’s grasp. Her other leg froze, literally and figuratively, as another tentacle wrapped around it, it’s cold slime quickly suffusing her fur.
Tahla gasped as the chill spread under her tail. She renewed her struggle as a tentacle slid into her panties and pulled them away. She moaned as it’s tips swirled around her entrance, the cold slime dripping into her. The young eevee relaxed as the chill spread through her nethers, her mind growing fuzzy. Her senses seemed to hone in between her legs as she felt a tentacle rubbing between her lips like a hotdog in a bun. She cried out louder as it pushed against her flesh, it’s length rubbing along her entrance and clit.
Tahla’s intoxication grew with each passing second. Her hands shot down to her crotch as she pulled the tentacle against her, grinding herself along it. It pulled out of her grasp and she groaned at the sudden lack of it’s touch. Her need was short-lived, however. Her passage, loosened by the slime’s effect, was suddenly filled as a tentacle plunged into her. She cried out with lust as she felt her walls stretched around it, as the tentacle seemed to grow and shape itself to fill her completely. Bumps grew along it’s length, pressing against her and shifting around. Her orgasm took her by surprise as it washed over her, making her clamp down over the invading appendage and cry out loudly.
“Tahla, are you okay?” Telain yelled as he burst through her door just as her cry died out, leaving her panting. She hung there before him, the translucent tentacle still stretching her lewdly in front of her brother. Tahla’s mind was hazy, but she snapped to as saw him standing before her.
“Tel! Quick, run!” she yelled at him, too late to help. He was grabbed and pulled into her room, his shorts quickly ripped off as he was lifted into the air. He hung next to her, his crotch inches from her face. Her eyes were transfixed as she watched a tentacle press itself against his sheath, flatting out against him.
“Tahla! What the hell is going on?” he cried out as he struggled against the tentacles holding him. Tahla watched as her brother’s sheath spread around his length. The deep red shaft grew rapidly as the tentacle undulated around him, coaxing it from it’s hiding place. Telain’s protests quieted as he moaned and pushed himself into the tentacle’s touch as it changed, an odd, more solid shape seeming to form within it.
Tahla groaned as she felt her own tentacle change shape within her, her muscles relaxing as it shrunk. She watched the shape around her brother’s shaft move away, leaving a hallow space around his length, as her own tentacle withdrew from her depths. She looked up at her brother and traced his gaze to her lips. She realized then, that at some point that her skirt and panties were removed, but what surprised her more was the end of the tentacle hovering next to her. Though mostly clear with a tinge of gray, it had the shape of a canine penis, not unlike that right by her face.
The twins moaned in unison as Tahla felt the tentacle press into her. She watched as it spread her open, then she looked back to Telain and saw the tentacle envelop his shaft. As she felt it withdraw, she squeezed down on it and Telain moaned again. His hips bucked and the length within her pushed deeper a moment. It’s speed slowly built as it thrust into her, the twins both writhing as their pleasure built.
Tahla’s eyes closed as she realized what was happening and her mind was filled with images of Telain standing over her, his shaft filling her rather than it’s tentacle replica. She squeezed the tentacle as tightly as she could and smiled as she heard her brother gasp above her. She felt a tentacle grow within her, stretching her entrance wider as it thrust into her. Just as it felt it would split her in two, it stopped, pressing hard into her and twitching, her walls involuntarily holding the false knot. She felt a sudden warmth deep inside and her eyes shot open. She gasped as she saw Telain cumming, his thick, creamy fluid filling the tentacle and moving along it. She followed the flow, and saw the two tentacles had fused and now she was being pumped full of her own brother’s seed. She reached out for Telain and took his hand, he squeezed her’s back and the twins locked eyes. They smiled at one another, the pleasure and exhaustion obvious on both their faces.
As the twins were lowered onto Tahla’s bed, they hugged each other tightly and drifted off to sleep. Later, when they awoke, Tahla told Telain about the mysterious book, but when they went to check, all they found at the foot of the bed was a pile ash with a few spots of gray goo.
