Emily is nominated as babysitter

Carly growled once more as hot black corruption spewed from her tentacles and filled her sister's every orifice. Carly was laying on the bed, Becca on top of her, and they stared into each others eyes while Carly ravaged each hole. Becca smiled around the smaller tentacle defiling her mouth as her stomach and womb simultaneously welcomed her putrid sustenance. Carly ran her hands over her sister's slimy form as she came.

They had been fucking all night, the five of them in various positions and couplings, but now, the sun had risen. And though Carly was loathe to end her time with these beautiful creatures of darkness, her and Becca had quite a day ahead of them. She stroked her sister's head as her appendages continued to listlessly work their magic inside Becca.

"Time to get up, sweetheart. Big day ahead of us."

Carly allowed the tentacle in Becca's mouth to retreat, a spout of black jizz shooting out before Becca could recover. She swallowed, then burped unceremoniously.

"Awww, Chi-Chi... I want more..." Becca whined.

"I know," Carly replied with a grin. "But you don't need any more, and you know it. Besides, as much as I'd love to keep defiling that tight little body, we both know that where we're going today will be a lot more fun."

Carly gently shifted her sister off of her and removed the rest of her tentacles. They slithered back inside her, the shuddering sensation threatening to make Carly lose her will momentarily. She shifted herself out of bed just in time to see Amanda slumped over, face on the floor and ass in the air, moaning lewdly as worms slid out of every hole. They erupted in steady sequence, one after the other, slime gushing out of her as her children wriggled their escape. Amanda's face was contorted in blissful ecstasy.

To the rear and front of her were Jenny and Emily, both with triumphant glee written on their predatory gazes. From the amount of worms Amanda was birthing, Carly assumed they had been plugging her for some time now, holding back her children as Jenny filled her with more and more spunk.

"Glad you three kept busy," Carly chuckled. "We have to go to campus soon, its Becca's orientation day. You guys have something to occupy you?"

"Actually," Jenny started, "I was hoping Amanda and I could join you? A couple of our friends go to NoCal, we were thinking maybe we'd turn them."

Carly smiled. "Sounds great, as long as you're careful. Don't want to blow our load before we even get started," she winked.

"What about me!?" Emily asked, indignation written across her face.

"Sorry babe, someone has to stay and guard the prisoner. She is yours, after all. Maybe you can debase yourself some more with her. You'll come up with something."

Emily huffed, but her rage was quelled. No one likes being left out, but an afternoon torturing her sister certainly had its appeal. She did worry, however. Left alone all day with her hottie of a sister ripe for the taking... this would be a true test of her will. Of her dedication to her Master.

"Yeah okay, fine. But you guys better come back as soon as you're done, I'm gonna be off the fucking wall by the end of the day!"

"Deal," Carly smirked.

Once the girls had showered the cum and slime off and picked out outfits from Carly's dresser, they made their way to the car.

Having a similar build to Carly and being mostly unchanged, Becca looked the most "normal", though she was still dressed in the sluttiest clothes Carly owned. A dangerously short yellow tank top that fit her like a glove refused to meet the jean short-shorts that hugged her perky bottom and nothing else. Her nipples subtly poked into the fabric, and her pussy drooled with slime in excitement, creating a small wet spot between her thighs.

Carly was similarly dressed, although her alterations had meant a longer black Star Wars T-shirt was required to keep her prodigious breasts under wraps. Even so, the shirt pulled up her midriff, exposing her bellybutton, while the pair of matching jean shorts did a similarly poor job of keeping her mouth-watering behind hidden.

Amanda was both much shorter and much bustier than Carly, especially as she was before. The only thing that really fit her was a simple black stretchy halter top, while a matching black pencil skirt wore her surprisingly well. Being much shorter than Carly, the skirt was depressingly long, reaching almost to her knees, but even she had to admit that it was an alluring outfit, if not overtly sexy like she'd wanted.

Jenny had been the most trouble. Much taller and bustier than Carly had ever been, they'd had to squeeze her into a baggy, plain black sleeping T-shirt that Carly kept around, and even that managed to look too small on her new frame. Another black skirt was required for Jenny, this one looser than Amanda's pencil skirt. Despite also being on the longer side, it only came halfway down Jenny's thighs thanks to her height, and the whole outfit was at least passable which the girls considered a victory given the circumstances.

They piled into the car in the driveway and made their way to the college, excited to start another project at a campus teeming with potential.
