Gaarn, being the youngest of four brothers, always went along with what his older brothers told him to do. Most of the time that included sticking his face in their asses and sniffing their farts, which he didn't mind too much- he liked being treated like a dirty fart sniffer. That very much hadn't changed with the latest mission. Let's head back in time for a second…

"I have missions all over the city, boys! It's important we have a base camp to serve as a… hub of sorts!" Kuxa chuckled into his communicator, on the other end was four Slitheen; Graax, Grirn, Gliln, and Gaarn. Their parents had sent them to help their uncle Kuxa with a new mission, and they were eager to join the family business finally. "Your mission is to infiltrate a police station in Walthamstow. There, you will find your skin suits and a cabinet in the chief's office. It's stolen Time Lord technology, should have arrived this morning… Humans are none the wiser." He snorts. "I'm teleporting you to the coordinates now. Contact me as soon as you have the skins and are safely inside the space."

Without any time for words, the four find themselves suddenly, not on a spaceship, but in front of a large police precinct, under the cover of darkness. "No time like the present, eh boys?" Graax, the eldest brother, spoke. "That was… fast. Nobody told me it was instantaneous." Grirn mumbled. "Come on, I want a skin suit now! I can't wait to hunt!" Gliln growled, his cock hard in anticipation. "Well, uh- good luck guys. Where are you all gonna hunt?" Gaarn asks, his brothers looking at him. "Well, I think it's fair that I'm the chief…" Graax smirks. "You guys can do what you want- just find a good fit. We have all this technology now, we don't need to be picky anymore!"

"See you tomorrow, Joe!" An officer calls, walking out the back entrance, Grirn skulking by in the shadows, catching the door with his claw and stepping inside. He prowls around, seeing a well-built man in uniform. Mmh… perfect. Without warning, he sneaks up behind his victim and taps on his shoulder. "What is it now, Theo," he turns around, seeing a snarling green monster, screaming as a claw plunges into his shoulder. A clean kill.

Meanwhile, Gliln made his way into the security office, skulking past potential skin suits- he wanted to find someone who would be fun to portray. Aha. There… a muscular dude, all alone… perfect. Gliln wonders what sort of life he leads.

Graax stormed into the chief's office, not caring about stealth. "Mmhh… I could smell you from a mile away!" He growls, approaching the chief. "Wh-what the fuck are you..? Is this some prank?" Graax laughs. "No, no prank at all… just the end of your life as you know it… only to be puppeted by me." He laughs as he raises his claw, his screams echoing through the building. He only managed to eat, skin and suit up in time before another officer walked in. "Sir, are you okay? We heard screaming from across the building!" Graax just shifted slightly, nodding. "Yes, man- just a little prank played by one of you lot. Scary face on the screen, you know how it is around here…" He cracks his neck, smiling.

Finally, there was Gaarn. This was his first time hunting solo, so he was pretty nervous… but there was still that underlying confidence that he had been brought up with. When he turned 18, his older brothers began giving him hunting lessons, knowing he'd be joining the family business soon. He took those lessons to heart… he just had to remember his training. He made his way through the mostly empty building, finding his way to the bathrooms- perfect place for a kill, only one escape route. He hears quiet sobbing coming from a stall.

"They're so mean! It's my first day, why was everyone so mean?" A young officer sobs into his phone. Graax feels a pang of sadness- maybe he should just put this human out of his misery. "You okay, Thomas?" He calls, noting the name from the badge on the rucksack outside the toilet cubicle. "H-huh? Hold on, mum- someone's here." He seems to end the call. "Who's there?" Graax thinks for a moment. "I'm… Bob." He clears his throat. "Uh.. I don't think I met a Bob today…" Thomas sniffles. "But if you're here to ridicule me, I've had enough of that today!" Graax just laughs. "Not at all, Thomas… I went through the same stuff myself, so… I know what it's like. Come out here and I'll give you a hug." He snarls sinisterly, but Thomas opens the cubicle door anyway. "I'm glad someone is welcoming, I've had such a-" His heart sinks when he sees Graax, shaking his head. "Don't worry, Thomas… I'm sure nobody will mess with you again when I'm the one inside your skin." Graax took his opportunity, pouncing forward and skinning Thomas, following every step his brothers had taught him. Once he had his suit, he pulled it on, zipped it up and admired himself in the mirror. He would have to get used to the glasses, but he liked his build… nice and fat. A great face for sitting on, which was his favourite pastime.

And so the three younger brothers made their way to the chief's office, opening the door and walking inside. "Nice suit, bro." Grirn complimented his brother's choice, smirking. "You three don't look so bad yourselves… nice taste." He smirks back, turning to the cabinet. "Time to get this working…" He gives it a bang on the side, opening up a panel. "Present DNA for inspection." He places his finger on the panel. "Identified: Raxacoricofallapotorian. Proceed." The back wall of the cabinet opened up, the four Slitheen heading inside the near vast space. "Damn, Time Lord's had it good…" The walls were a repeated pattern of hexagons, much like the TARDIS, but it was obvious some retrofitting had begun, with small rooms offshooting from what was the main console room.

"Suppose we'd better contact Uncle Kuxa… show him that we've done it."

And so they did, showing their uncle proudly what they'd achieved so far. "Hah! Perfect. Now you'll just need to do the place up, make it into a proper Slitheen base camp! People are going to be sleeping here, having a drink, a chat, a shag… oh, and some will need suits too! That police precinct is known for taking in a lot of criminals, use them."

"Well, we'd better get to work then."

Within weeks, the place is completely transformed. The walls are emerald green, and the main room is complete with a bar area, which serves exclusively Rakweed and non-acidic alcohol. There's bedrooms, skin wardrobes and a dungeon, fit for torturing humans, whether that be for information or just for fun. The brothers look around at their handiwork, and then the three eldest look at Gaarn. "What? Is there something on my face?"

"Not yet."
