A wet and windy morning for your first day teaching at a new school is never a good thing, but it didn't particularly bother Mr. Jeffery, the newest science teacher. He had passed the interview with flying colours, and managed to keep it together throughout the whole thing. His skin ached, itching around the legs. He needed to be naked- but not here… You see, Mr. Jeffery was a Slitheen. He was fairly certain he was the only one in the current location, but you can never be too sure.

As he walked into the staff room, someone took his attention first off. A chubby, bearded guy with wide hips, a fat belly and what looked to be a fat ass. It made Jeffery squirm a little, telling himself not to make a fool. He approached, sniffing indiscriminately, when he picked up a different scent- that wasn't human…

"Ah, you must be the new science teacher. I'm Mr. Jackson, Dan to my mates, I teach biology- I believe I was told you teach chemistry. Correct?"

Jeffery nodded, "Yes, I'm here to offer my teaching services to the school!." Dan smirked. He could smell something was off about Jeffery, he smelt familiar somehow.

A booming voice cut off his thought, "Has anyone seen Mr. Roth and Mr. Webber?" Shrugging and shaking heads fill the room.

Jake roughly kissed Lloyd in the former's office. "You're so hot, it hurts," Jake, known as Mr. Roth around school, moaned. Lloyd, known as Mr. Webber, smirked, "You're hotter." Jake felt his stomach tensing, gurgling very quietly. Oof, now might be the time to… BRRRRPT! "Ooh, sorry about that Lloyd… I had a heavy breakfast." Lloyd just laughs, "It's endearing! Now, where were we?" He begins kissing Jake again, grabbing hold of his love handles and pulling him in closer.

PHHBBBTT!

BRRPT!

FRRRRTTTT!

"Jake! This is ridiculous now-" Lloyd complained. "I thought it was endearing…" Jake chuckled, "After all, you'll be in the same boat soon enough, my lover…" He smirked menacingly. Lloyd hadn't noticed the bookshelf open discretely behind him. "What do you mean? Jake, you're scaring me."

"Stay very still, my love… it only hurts for a moment." Jake begins to laugh. Without any more warning, the Slitheen behind Lloyd struck, killing him with one swipe of a claw. "Thank you, my brother… the final suit. What a body he has too… Help me convert him, I'm starving." Graax demanded. Jake nodded, a little hard from the anticipation. He helped gut the disguise, feeding Graax endearingly as he went, then helping him get into the suit. ensuring the compression field was active. He pulled up over Graax's fat ass and belly, and up towards his head. Upon zipping the suit up, Lloyd adjusted himself. "Ooohh, this feels good..! Plenty of room, yet still enough compression for the gas exchange to work its magic." He punctuated the sentence with a loud fart, PHHBBBBBT! "Oh, you're so much hotter now, Lloyd!" He pulled out his human disguise's penis, which was now green as it throbbed through the skin suit. Lloyd began to do the same, but then the first bell rang. "Ah, shit! Meet back here at break time, bring Gaass!" The two men put their members back in their trousers. And with a couple farts from the two of them, closing the bookshelf door, they were out. PHHBBT! FFRRRTTTT!

Dan passed Jake in the hallway on the way to their classes, slowed down and began a conversation. "The final suit has been acquired, we can finally truly blend in. Graax took the form of Mr. Webber.. what a body!" Jake smirked. "Good- but there's something else… that new science teacher, he smells… different. Somehow familiar."

"Do you think he could be.. like us?"

"Perhaps… let us see at break." Dan looked around, making sure no students were around. None, good, they were in their classrooms. He smacked Jake on the ass, "As you were, Mr. Roth!"

Jake left the hallway horny and gassy.

"Welcome to biology..!" Lloyd feigned interest, this disguise was obviously some kind of science nerd. The only biology Lloyd cared about was the gas exchange- his stomach rumbled. "Open to page 194 in your textbooks, today's lesson concerns the human digestive system-" PHHHHHHRRRT! "I'm sure it does, sir!" The classroom erupts in laughter, "Shut up! Silence!" Lloyd growled, showing a little of his Slitheen side as he barked the order. The class quietened down, the laughter turning to a small chuckle. "Good. Now, page 194…"

"Now, chemistry is interesting because of one simple reason, can anyone name me the chemicals in water?" Jeffery hoped this very simple question would ease him into this new class. A deafening silence. "Really? None of you?"

"Stupid humans, haven't figured out string theory and an adolescent can't name the two elements in water." He muttered under his breath. "Well, try this one. What happens to aluminium if heated on a hot flame?" Another silence, maybe one or two small coughs. "Come on, class, don't be shy. I know I'm a new face, but I don't bite," Jeffery smirked "unless you ask me to." One hand raised. "Yes," Jeffery pointed to the boy. "The aluminium would react and become a bright light?"

"Finally, some intelligence in this classroom! So, how would we write the equation for that, well…" Jeffery turned round, writing on the whiteboard. Whilst writing, he felt something pelt one of his buttcheeks. He turned quickly, "Who threw that? I will not tolerate troublemakers in my classroom!" He pointed to a child, who looked off somehow. He approached the desk, resting his hands to lean over the child. "Think you're funny? Class clown, noted." BBBRRRUMMP! "Oof," he walked away, letting the smell dissipate. The class laughed. Jeffery just ignored them, and continued teaching.

The bell finally sounded, marking the end of first period. Dan stretched his neck, waving the class out. "Go on, out you go. Get outside, it's a lovely day!" He smirked, looking out the window at the rain. He looked back to see Mr. Jeffery walking past. "Ah, Tim! Come in here a moment." He gestured, mimicking shutting the door. Jeffery shut the door, walking up to Dan. "How was your first class at Park Vale? I hope it went well for you!" He walked around the room, shutting all the blinds. Jeffery thought this slightly odd, perhaps it was a strange human custom. "It was great- a few troublemakers, the odd class clown… but I managed. Though, I have to say, the intelligence of these students is… concerning."

"Oh, tell me about it," Dan finished shutting the final blind. "It's like teaching a brick wall half the time. Now, Mr. Jeffery… tell me of your home town. Where are you from?" He sat in his chair, gesturing for Jeffery to pull up another. "Oh, well, I come from a… faraway place, let's just say that." Jeffery chuckled nervously. Was he about to be found out? He didn't want to have to kill Dan, he'd been so kind so far- for a human, anyway. "Oh, come on… I bet we have very similar upbringings," Dan played with his fringe for a moment, on purpose, flashing something silver to Jeffery. The other teacher stood from his chair, "No way, I'm the only…" He then shook his head. "Okay, this is going to sound weird but, I need you to fart for me."

"Do you now? Usually I wait until I'm in bed to ask that."

"I need to smell you… to make sure."

Dan sighed, turning round. "Well, if the obvious zipper wasn't enough, have a blast of this… nngh..!" PHHHBTTTTRRTT! BBLLRRP! PRRRTTT! FRRT! Jeffery sniffed like a madman, "Hah, it's really- I'm not the only one here-!" Dan smacked his own ass, "I'm not the only one in the school… come with me."
