Sam is probably like any other teen when it comes to what he likes and doesn't. 
And, today, he totally didn't like the brat kid that was blocking his way from the elevator exit. 

He's stuck in an elevator with this wolf kid who think he's hot shit, who couldn’t be older than 10 years or so. 
“If you wanna get past,” he said - high voice contrasting the imposing figure he was assuming, blocking the elevator doors entirely. 
“You're gonna have to smell my ass!”
Sam blinked for a couple of seconds, then bursted out laughing. 
“What kind of fucked up, gay shit, is that?”
The wolf kid looked pretty stern about it though, as evidenced by walking right up to the teen, and making him press up against the wall. 
Sam gulped. Maybe it was a bad idea to mess with this kid. 
“Don’t fuck with me, fox. Remember who I am.”
Sam frowned; who is this guy?
He could sense the wolf’s musk reaching up to his nose, stifling his thoughts and making his sheath stir, all subconsciously. 
Once the wolf noticed the fox teen smelling his musk in, he smirked bright and widely.
“My name doesn’t matter. All that matters to me is that you know what your place is, like a good little fox boy.”
Sam balled his fist together, anger coursing through his veins. 
“You can’t talk shit to me, kid, and expect to take it. Move aside, now.”
Suddenly, the wolf looked all scared - quivering in fear, and following the fox’s command.
Once he did so, Sam smiled with contentment, almost struggling to believe that the wolf backed down without a fight. 
Once Sam approached the open door, the wolf sped to the control panel on the other side of the room - and smashed a random button, prompting them to be closed as soon as the fox was about to step out. A second later, and Sam’s leg could’ve been snapped right off.
He stopped, moved back a bit, anger evident on his face. 
His words dripped with venom, “You’re such a cheeky little shit.”
Sam isn’t the type of teen to start a fight (in fact, he tries to avoid them at all costs), but the wolf was really pissing him off now - and he was about ready to knock him one. For good.
What he saw when he faced around, was the smug, little, pleased face of the boy and that just pissed him off further. As Sam was going for in for a punch, the wolf runt easily slid out from view - and jumped on his back in less than a few seconds.
“You sly little runt!” He said, voice trembling on the brink of tears.
“I forgot. Big strong wolves never submit to small foxes. After all, you are our slaves.”
Sam felt tears streaming through his eyes. First, the wolf pissed him off. But now he is just tormenting him; stating truths that he hates to hear - the fact that foxes are slaves to wolves. All due to a bad-mouthed kid four years younger than him. The humility was immeasurable.
“Awww, don’t cry, little foxy~” He said, mockingly.
The wolf jumped off the teen’s back and stood in front of him - shoving his behind in his nose.
The fox hated the smell. He hated being made fun of. He just wants to go home.
“You gotta smell my ass, remember, if you wanna pass.”
Through clenched teeth, Sam carried out his order. His stupid, fucking immature, “gay” order - in his own words. He’s not into this. He’s straight. He just wants pussy in his face, not some smelly kid’s ass. But fuck that. He’s gotta go home, no matter what. And, as is fox tradition, he must obey the orders issued by a wolf. No matter the age...  

The wolf continued his beratement. 
“I won’t deny, I don’t care for this gay shit neither. I’m not a pussyfag, and neither are you. But there’s one thing that you need to know. You are fox, and I am a wolf. You are my slave, understood?”
The boy’s soft voice was so weird to hear with that type of language, but he was right. 
Sam couldn’t speak. All he had was a faceful of sweaty cloth, with his nose buried right between those small cheeks - into the clothed musky crack of the boy. 
To be honest, it wasn’t really musk. The boy’s undies were dirty; unclean. No wonder the kid smelt. 
The wolf chuckled again, “You can have this… I’ve been keeping it in all day.”
Once the wolf shoved his paw on the back of Sam’s head, the fox knew he was going to be in for some deep shit. Literally. Because the boy ripped out a fart on his face, giggling like a kid does, squealing and happy with relief of letting out a massive fart he’s being holding in all day - all at the displeasure of a slave; a fox teenager older than him forced into servitude to eat, smell and lick his smelly ass.
It was great. Life was great for the wolf in this moment, it was like he has achieved a newfound pleasure of which to take advantage of. Sheer dominance, that is. And he’s just beginning! 

“Look at you, just eating my farts, like a good fox slave would. Now rim me.”
Sam couldn’t say anything, he just wanted to breathe in as little stink as possible. It was kind of impossible though, seeing as the cub’s ass was just straight up in his face. This small, stinky ass, belonging to a kid with a kind of “don’t fuck with me attitude”. And, hell, even if you fuck with this kid - he’ll torment you one way or another. That’s what Sam doesn’t know. He really gets off on this feeling of dominance.  

The wolf slid down his pants, exposing his bare furry, plump ass - then just shoving the fox’s head back in between to that crack, making him inhale it all up - whether he likes it or not.
“Rim.”
That was just the one order that Sam had to follow.
Surprisingly, this time, the wolf gave him chance to speak.
“But you told me to lick-”
He shoved his head back down again and spat on his face.
“You are not the one giving orders, slave.”
That broke Sam. He let out a small sob, tears running down his eyes. Slowly but surely, his tongue touched the stinky, dirty butthole of the boy - going into those musky depths with his face grimacing. His tongue could barely bring itself to touch the rim, but he did so anyway. 
The wolf sighed out happily, content with his worship that this teenager, a guy older than him, is giving him.
“Yeah, I think that’s good enough.”
The wolf unhinged his grip on the fox’s head, and he came flying back to the floor with tears in his eyes and a sniffling nose.
He couldn’t even look back up to the wolf because he was so ashamed. Instead, with a face bright red, he simply ignored him - got his bag - stood back up, legs shaking (and putting on a brave face) before racing out of the doors which barely opened in time for him. He sped home, crying, without ever looking back. 
The wolf found pleasure in that. Why? Because at least the fox knows his place now!
“Well, time to find another slave.” He said, walking down the mall himself, behind the fox he just traumatised, with a pep in his step and a sneer on his face.
