Carly, Emily, and Amanda

"Just like, stick a finger out."

"But what if it hurts?"

"Oh for fuck's sake, here, I'll do it."

Carly stuck her hand out the doorway, and into the sunlight. Nothing happened.

"There. We're not vampires. Let's go."

The trio of girl's headed for the car. It was a bright summer sunrise, so it was still very early. But by the information Emily had given, they should arrive at her place as her parents and her sister were waking up to get ready for school and work.

When they arrived, they parked the car in the driveway, and headed right in through the front door. Emily's dad was standing facing her mother in the living room, just off the entry. Emily's sister was sitting on a chair in the corner, picking away at a basic breakfast while on her phone. She looked disinterested.

Emily's parents were clearly in heavy conversation as the trio entered. When they saw Emily, relief washed over their faces, quickly followed by surprise and confusion when they saw the other two gorgeous women enter, wearing nothing but coats.

"Emily... Emily where have you been, were you out all night? Where's Mark, I want to speak with him! And who are they!?" Emily's mother frantically rattled off.

Carly sized up her prey. Emily's mother was pretty, but average. Average height, weight, and an average face. Both parents had pale skin like their daughters, but Emily's mother is clearly where she got her blonde hair from. She was surprised to notice her sister looked very similar to Emily, but her hair was nearly black. This she must have got from her father. And, Carly noted, where both girls got their exceptional looks. Emily's father was a hunk!

"Yeah... I don't really wanna go through a bunch of setup on this one, I just wanna fuck," Emily rolled her eyes. "Carly?"

That was her cue. Carly took off her jacket, revealing her gorgeous body, and while the family was too stunned to say anything, Carly's tentacles shot out of her. The first one, her thick, central tentacle, came rocketing out of her pussy and wrapped up Emily's dad, coiling around him like a snake to hold him in place and stuff his mouth to stop him from talking. Each of her back tentacles performed a similar function on Emily's mom and sister.

Emily walked over to her dad first, and produced the thin, smooth worm that she had in her jacket.

"You know, I always low-key wanted to fuck my dad," Emily giggled. "I think this way, it'll be so much better than even my fantasies!"

Emily worked around the tentacle holding her father to remove his pants and underwear, freeing his cock. To everyone's shock, he was rock hard.

"Oh fuck, daddy!" Emily squealed. "You like this!? Oh, you're gonna be so good as a demon..."

Emily's father shouted, muffled by the tentacle in his mouth, as Emily produced the glowing worm. His cock wasn't huge, maybe five or six inches, but the worm had no trouble diving right in. All three girls watched in fascination as it crawled inside his dick. Carly suddenly realized that he wasn't shouting into the tentacle any more, but moaning. Either the worm had a way of making this grotesque act feel good, or her dad was into some seriously kinky shit. Well, it didn't matter now. Either way, he was about to become their first male demon.

Emily was practically hopping up and down on the spot as the vile worm slid inside her father's cock. It didn't take long for her to lose control, diving on her dad's dick and swallowing the tail of the worm as she desperately worked to get every inch of him inside her mouth. Carly heard Amanda release a small, indignant huff as Emily temporarily impeded the worm's progress, but she stayed her feet. She knew that Emily would never do anything to stop this from happening.

As soon as the last of its' body was safely inside, the worm began to dissolve. Her dad's cries grew louder and more pleasured. She knew what this process felt like when done right. She quickly removed herself from his cock, choosing to watch with enraptured excitement as his cock started to twitch and move, elongating and thickening, while taking on the red glow of the worm that had entered it. Emily's demonic lust was reaching critical mass, and Carly could see. She felt the process complete itself, and immediately released Emily's father. He fell to the floor on all fours, still fully clothed, minus his new, demonic cock jutting toward the ground, pulsating angrily. It was now just over a foot long, and nearly as thick as one of Carly's back tentacles.

He slowly stood up, his eyes glowing red. Emily was squirming with pent-up passion.

"Welcome to the fold, daddy!"
