Three's allowed

Morrigan Jansson hated walking home at night.

Even when there wasn't some sort of emergency going on.

You weren't supposed to keep your head in your phone, especially at night, but she just had to know.

Problem was, nobody really knew what was going on. There were weirdos saying it was aliens, but Morrigan had seen much better pranks.

The photos and videos looked like something out of an old movie.

So she rolled her eyes, but kept scrolling. There had to be some useful informa-

And then she bumped into something large.

Something much softer than a tree.

Reflex made Morrigan say, "Sorry," step back, and look at the other guy.

The other guy was a girl.

Morrigan could tell, because of the massive boobs at eye level.

She looked up, and found a nightmare.

A nightmare that smiled down at her.

Morrigan kept backing away. Her shoes crunched on the gravel path, until she bumped into a similarly soft thing behind her.

Uh-oh.

How had they snuck up on her? They were on a gravel path!

Morrigan stepped forward, once. And darted to the side.

She didn't get very far.

They didn't even bother to take off her clothes. Not entirely. Just enough for them to gain access. Enough for her to feel the cool air dance across her skin.

Some green liquid dripped from their mouths, to the ground, past-

Well, something else dripping green.

They took a second to enjoy themselves. To watch her crouch, stunned, terrified.

Then their tails curled around her waist, and they lifted her into the air, and - carefully - slid themselves into her.

A moan escaped her lips. She wasn't sure why. Fear? Something else? Whatever it was, she tried to hold it back.

The two monsters laugh. Or so Morrigan assumed.

And then a voice without sound whispered, Cry out, new sister. Join your voice with ours.

Morrigan blinked. What was that?

One thrust into her rear, and sent her forward. The other thrust into Morrigan's front, sent her backwards. They didn't give her a second to rest, under that ****. They filled her more than she ever dreamed, more than she thought possible.

And then the tingling crawled up her spine.

She didn't say anything.

Not out loud.

Some part of her moans, Yes...yesss... A small part.

But it was growing.

And the monsters heard it.

More...please...

Something strange happened, where their cruel claws grasped her. She couldn't feel them anymore.

She looked down. Her new night vision made it was easy to see the way the alien's skin sort of...melted into her sides.

Or maybe _she _melted into it.

Fangs tore their way free from her gums. The twins laughed, but something deeper lurked underneath. Something happy. Anticipation, maybe.

And then things got very complicated for Morrigan.

For as long as she existed as a separate entity.

Which wasn't very.

The creature stretched.

Its three heads rested upon long necks, necessary to give each room. Three pairs of breasts trailed their way down its front, above the dual cocks. The tail that snaked out of its wide rear was tipped with a phallic head that dripped green onto the grass.

All in all, a stunning package. For various reasons.

They bought their arms down, and used all three pairs to cup their breasts.

What shall we call ourselves?

Shiva? Cerberus?

A moment of thought.

Perhaps...Hydra?

The name resonated through them, through the hivemind. And it sent back approval.

The three heads smiled.

Hydra it was.

Author Note: This is the end.

No, not for the story, for Hydra. That's all I've written about her/them.
