Like a werewolf, but also different.

Finn recovered slowly on the couch from his groggy state. He felt awful, stomach churning as if from a hangover. After a few minutes he had the strength to stand up and wander to the bathroom. Plodding, he almost tripped over his pants. They felt long and baggy now, and almost slid down over his hips despite his belt. He hoisted them up with one hand.

In the bathroom he vomited, stayed still on his knees for a few minutes to recover, then got up to brush his teeth. Halfway through he took a look in the mirror, a real look.

He recognized himself, despite the thinness and lack of facial hair of the face looking back at him. His shirt was drooping, baggy and ill-fitting especially around a stick-slender neck. He took it off to see what decimated physique looked like.

His waist and ribcage were many inches smaller, muscle almost gone and ribs showing freely. His arms were stick thin. And was that...? Yes, he saw as he stretched and angled his chest - he had two little mosquito bite tits.

It began to sink in then what must have happened. With breath held he shucked his pants to the floor, not even needing to unbuckle them to fit them over his skinny hips, then pulled down his boxers.

His lip trembled as he looked in the mirror at the simple patch of brown curly pubic hair between his legs. But he had to prove it to himself. He pushed his hand down and slid a finger into the slit hidden underneath his pubes. The sensation was alien, totally unlike touching his dick. And... Not unpleasant. But he was too sick with the realization of his transformation to enjoy it. He took his hand away, trembling.

"Hey Fiona. Hmmm, a lot less excessive of a change than I'd have guessed. You almost look like a boy."

Finn - Fiona? - whipped her head around to see Stacey staring at her, her expression bored and anxious and pissed-off all at once. She was wearing an uncharacteristically baggy robe that hid her figure.

"What the fuck did you DO TO ME STACEY!?" Fiona screamed, looking around for the marker.

"Shut up bitch," Stacey said.

In shock Fiona did, if only momentarily.

"It wasn't me, I couldn't have and you know it. It was Krissi."

"Fuuuuuck. You let her get the marker?"

"FUCK YOU! You were so smug you let her roam around and didn't think anything could go wrong. You told me to go in there! And now look where it got both of us."

Stacey stepped towards Fiona and as she did so her robe parted and her monster cock, fully erect and pointing at an acute angle towards the ceiling (it was a superhuman monster cock after all) popped out. Stacey stared Fiona in the eye, and the newly-transformed girl found the look frightening for some reason she couldn't yet figure out.

Slowly, Stacey turned, letting her boy/girlfriend see the marks that remained on her.

"She crossed out a couple and I cleaned most of what I could off. Not much point keeping it right? Thank god she didn't make everything she wrote permanent. She cleaned you off completely except for, well..."

Fiona noticed it was true - only WERE-SKANK FIONA remained on her neck.

"Uh, that one about humiliating Fiona - uh -"

"Am I gonna act on it?" Stacey said, and there was a dangerous glint in her eye.
