Pizza Girl

The delivery girl almost panicked when Natalie opened the door again, holding the open box of pizza in one hand and a half-eaten slice in the other.

"Did you want to come in?" Natalie asked between mouthfuls.

Aaron saw the colour drain from pizza girl's face as she stammered a refusal, but Natalie interrupted her.

"Sh-sh-sh-shut the fuck up for a second. You're still standing here because you want to know why I'm naked like this, and I can promise you the answer is hotter than you could possibly imagine. Now you can still leave and finish your shift and keep your job or whatever, but for as long as you live, you'll wonder what the fuck was going on here. OR you can follow me inside, I'll show you something that will blow your fucking mind and we'll have an amazing night together. And even if you do get fired for skipping one goddamn shift, you'll have a crazy-ass story to tell for the rest of your life."

Natalie stepped to one side, holding the door open for the delivery girl who looked around nervously before stepping inside. She even flinched as the door closed behind her.

"Good girl," Natalie said cheerfully. "What's your name?"

"Um... Allie."

"Nice to meet you, Allie. Now take a seat over there while I stuff my face. I haven't been human for very long and pizza tastes SO much better than my body remembers, so I wanna enjoy it."

Aaron watched Allie walk in stunned silence to one side of the kitchen table while Natalie wolfed down half of the pizza, throwing the rest into the fridge and washing her hands before coming back with a can of soda. Allie stared at her untouched can for several seconds before speaking.

"Did... I thought... did you just say you're not human?"

Natalie held a finger up to silence her while she skulled her drink, setting the can down and belching loudly.

"Of course I'm human. I just said I haven't been human for very long - I'm an alien that ate this girl's brains and stole her body, and I wanted to try some junk food to see what the big deal is."

Even below table level between Natalie's thighs, Aaron could sense the rising panic before Natalie interrupted with a snort.

"I'm fucking with you. Come on - I'll show you what I've got planned for tonight."

Thoroughly off-balance and lacking the will to protest, Allie let herself be led by the hand into the bedroom, only to stop dead when she saw Sasha's naked body lying on the bed, Aaron's penis laying limp across one thigh.

"What do you think?" Natalie asked, moving behind the transfixed Allie with the multitool in one hand. "Pretty cute, isn't she?"

"She?" Allie breathed. "But... she's got... I mean..."

"Don't be such a prude," Natalie chided. "She comes with a bit extra, but she's still beautiful, right? Look at that face, look at those eyes."

Allie, finally having enough, slowly backed out of the room, her head shaking. Natalie let her, having already pinched her spirit from her body and was now holding it behind her back.

"You don't want this? I can give you this body, if you want it. You can be sexy and fit and you can experience what it's like to cum your brains out in a girl's hungry snatch. Doesn't that sound interesting?"

Allie had fully backed out of the bedroom now, and when she bumped into the wall behind her, she spun around and ran for the front door.

"Too bad," Natalie sighed as she dropped Allie's spirit onto Sasha's body. "It's not like you had a choice."

There was a messy collection of thumps outside the bedroom as Allie's body collapsed in mid-run. At the same time, Sasha's body violently shuddered as Allie's soul filled it. Natalie pounced before she could get up, pinning her arms and legs down while Allie's senses transferred across. Even from his inconvenient vantage point, Aaron could see Sasha's body come to life slowly. First her feet and toes arched, looking for contact with a floor that no longer existed. Her calves and thighs were next, still struggling to run despite being restrained. Sasha's hips twisted and her stomach arched, her chest heaving in air in its struggle to break free. Shoulders, arms, hands and fingers spasmed into life and finally Sasha's voice gasped out as Allie's spirit took full control.

The sudden shift from one body to another clearly had Allie in shock, and she didn't try to escape as Natalie climbed off of her and helped her sit up in her new body. Natalie watched with an intense glee as "Sasha" examined both sides of her hands, flexing her fingers, running them up and down "her" arms, taking in the sight of "her" breasts and "her" thighs. Allie's original body was a scrawny, gangly thing, and now she found herself in one that was taught, tight and stacked.

Still lost in her amazement, Allie let herself be led to the floor length mirror where Natalie stood by her shoulder. Aaron watched the stolen bodies of both his sister and his girlfriend drink in the sight of themselves together.

"What do you think?" Natalie finally asked, her face stretched into a manic grin.

Allie raised her hands up to new her face, framing her cheeks between her palms.
