Strange impactors

Kelli stepped out of her car, stood up, a little unsteadily, and looked at her Kia.

And winced.

Not just from her throbbing head.

Good thing the other guy didn't hit on the driver's side.

She frowned, and looked across her hood at the other guy.

And blinked.

Maybe that airbag deployed harder than she thought.

The other car's windshield was covered in glowing green goo.

Kelli blinked again. Maybe the other guy had harked up a glowstick.

When she told the operator, the other woman asked if Kelli could get an angle on the driver.

Kelli said yes.

Even though she wanted to do nothing more than lie down and take a nap with an icepack on her forehead.

As she circled the back end of her car and approached, the pounding in her head invited a friend to the party; nausea.

"The...the chemical smell is getting stronger. I think it's coming from the other car."

Did Kelli see any leaks?

She looked down. "No. Not yet."

Any sight of the driver?

The other car's side window was cracked, too. Kelli bit her lip, leaned in, reached for the handle...

And the door swung open.

And someone flopped out.

There was...something wrapped around his head. Something dark and...organic? Rubber? Silicone?

And it was changing him.

The dark thing stretched his head, elongated it. It stuck close to his cheeks, until it seemed Kelli could almost see it coating the muscles in his cheeks, even as he clawed at it.

The operator wanted an update.

Kelli was a bit too busy backing away to answer.

The man went limp, stopped clawing at the thing on his face. His chest stopped heaving.

He's not breathing?

What should she do?

The man twitched.

Or, more accurately, part of him twitched.

Kelli stared at the stranger's pants, as he instantly got the hardest hard-on she'd ever seen. So hard his pelvis thrust into the air, at nothing.

If he didn't calm down, he'd pop the zipper.

Was that some sort of brain damage, from the lack of air?

The man relaxed his pelvis, then thrust into the air again. Relaxed, then thrust. And-

And something started to leak through his pants.

Kelli's nausea got stronger. She backed away another step.

Another thrust. More leaking. And it was-green?

Kelli looked at the man, then looked at his windscreen. And the possibilities rapidly narrowed.

Either this was an extremely elaborate, extremely dangerous prank, or-

She looked at the man's head. The dark substance was somehow molding his cheeks. And-were those lips? A woman's lips?

"He's changing," she whispered into her phone.

The 911 operator said, "What was that, ma'am?"

"He's-he's-he's transforming!" She wound her free hand through her red hair. "There was something in his car, and it's doing something to him-"

"Ma'am? Ma'am, you need to calm down."

Calm down?

Kelli laughed, a trifle hysterically.

The man on the ground kept thrusting. The green soaked through his pants, ran down to his hips.

Which...were getting wider?

His hand came up, and grabbed the side of his own car. It looked a little thin.

Also, his hand went cut through the side of the car. Just punched a hole right through.

It was probably plastic, but that was still something nobody normal could do, no matter how long their nails were.

And he started to pull himself up.

Probably a bad sign.

"I need to...I need to find someplace," Kelly said. "Someplace like-" She whirled around, and ran around her car again, and yanked at the door. Which refused to open.

Why did I close it?

"Wait," someone rasped behind her.
