Thought to be nothing but a 'family friend', Mr Wolf adequately masqueraded himself for Aki's 11th birthday party.
The dress code was 'rabbit'. Luckily for Mr. Wolf, and perhaps not so surprising for the rest of us, this 23-year-old down-bad cubophile has no shortage of child-like onesies in his wardrobe to choose from, so dressing for the occasion was not an issue. What he had to work on was his instincts. 
When surrounded by so many little ones, how can he hope to hide his boner? Simply put, he won't. He'll make that onesie bulge out like a proper man would do, and he'll make friends with a lot of boys, only to drag them for a 'quick word' in the quietest, farthest reaches of the garden - as far away from the parents as possible. 
That's when he would drop the act - lower his shoulders, relax his pose, and thrust his hips forward, displaying his big package to Aki, who seemed quite happy to be getting a look at the famous wolf's 'secret weapon'.
"Wow sir, it's sooooo big!" Aki shouted out, making the wolf wince and hush the boy.
"Quiet, kid. Keep it low, alright?" He muttered, looking around him to make sure that nobody heard, all while Aki's little fingers were exploring his oversized bulge.
Aki looked up to the wolf, his big blue eyes betraying pure innocence to the perverted wolf.
"Ooooh... okay, mister." he replied in a hushed tone, somewhat theatrically.
The two had met on a site known as CubLovers(.)net. 
Aki was certainly the first to initiate the interaction (as we are well aware, Toby from a previous fic also got caught in this trap), but Mr. Wolf, doing what any normal wolf cubophile would do best, instantly asked for his age. From there, the interactions spiralled further into sexual discussion, until the two agreed to meet at the boy's birthday party.
"I'm sure my parent's won't mind!" Aki was convinced he would be feeling up Wolf's 8-inch dick even if he would die for it. 
But, Mr. Wolf was, at first, quite unsure on going ahead with the ordeal. Though he is an experienced cub fucker, with many meetups under his belt, this one just screamed 'red flag'. 
In addition, he also feared that it would be hard to explain to the parents that, somehow, their 11-year-old boy was talking to someone twice his age - who is single, and awfully handsome, from several states over.
But, when he arrived, Aki's parents barely shot him a look of acknowledgement. That's when he knew, this one's in the bag.
Mixing with cubs is the easiest part. After all, it's what Mr. Wolf is highly experienced with. It’s the attempt to not arouse any suspicion which he has to be careful of. Though, judging by his parents' behaviour, Aki could shout out "I LOVE DADDY DICK!!!" and his father would nod dismissively, asking Aki to tell his mother the 'good news', before opening another can of beer to drink away his life with.
It's not like they support it. His parents literally don't care. And that makes ample room for cubophiles like Mr. Wolf to enter Aki's lonely, sheltered life.
"Huh, you're right... Your parents literally don't care," the wolf chuckled, and then noticed Aki's discouraged expression. For once in his life, he felt a feeling other than lust. Pity.
"Aw, don't be like that kiddo, chin up!" The wolf scratched Aki's neck fur lovingly, making the cat purr out loud.
"Awww..." he broke out into a wide smile, and shuffled himself closer to the young boy, so that his warm bulge is pressing up against his face.
"Go on then, kid... Show me how much you love daddy back."
Aki felt his senses flare up. His entire world was wolf musk.
Tears were falling from his eyes, not because he's upset, but because of the sheer scent of Mr. Wolf's big, grown-up adult crotch.
"What's this?" Aki asked, groping the wolf's large nuts. The man moaned, having to support himself up by the tree trunk.
Getting groped by curious kids is the best. They never know what's coming next. They never know how big Mr. Wolf is until they meet him in person. No amount of nudes can do his package justice. He is a famous cub fucker for a reason.
"Now... If you w-want to unzip me, kiddo, I really don't mind..." Mr. Wolf said, finding himself short of breath. It's been a long time since he's had an excursion like this. Even longer since he's met such a cute, curious, and innocent cub who literally doesn't know the first thing about a man's genitals, despite acting all high and mighty online.
Aki, of course, took Mr. Wolf's statement as a commandment. He will always do whatever an older male tells him to do. Why? Because he doesn't get attention elsewhere - where is any place better for him than when he's fondling a man's crotch? Soon, he wants to learn how to suck it. Then, he wants to take it up the butt. He lives to serve.
Unzipping the wolf's onesie, Aki got his first glimpse at what a grown-up man looks like: hot as fuck. "You're so... warm!" Aki boasted out, rubbing his face into wolf's fluffy chest. Wolf, meanwhile, could think of nothing but rubbing Aki's face in his hairy crotch. Or sweaty ass. Either works.
"T-Thank you," the wolf stammered. He's never been this flabbergasted by a cub before. He's usually the one to take control of a situation. 
But maybe it's Aki's interminable innocence that is having this effect on him - he feels like he wants to protect the boy; to give him cuddles after a session of hardcore cub sex.
Then, the cub's arms travelled down his heaving body, to his musky, rock hard cock, bouncing in front of a youngster's face.
"Please..." Wolf moaned out. His eyes were half open, his body was leaning back against a tree, and he was begging for a kid to suck his angry, needy cock.
As soon as Aki opened his sweet little mouth, and wrapped it around Wolf's pulsating cock, the cubophile descended into moans.
"Fuuuuck yes baby, suck me off, suck daddy wolf off..." Wolf took Aki's head, stroking his hair carefully, but being quite firm with his grip.
Then, Wolf decided to let his inner beast out to play.
He plunged all of his cock down the boy's soft little throat without a second thought, hearing the kid squeal and vibrate about his member.
"FUCK!" Wolf shouted out, unable to comprehend his instincts. He is going to be controlled by his inner beast.
"I JUST. NEED. TO FUCK CUBS!" 
With every word forced out of his mouth, Mr. Wolf yanked Aki's head from the base and tip of his cock like a fleshlight.
Aki cannot handle this betrayal, but Wolf fucking loves it. He feels like his true self in this moment, as if all preconceptions were shed, and he's allowed to be a true man in this shithole of a society which works against naturally-cubophilic wolves.
Wolf's ears, in the midst of his rampant bestial facefucking (or face raping), picked up on the sound of crunching leaves.
"Son?" A deep, curious voice called out. That was surely Aki's fathers. Aki's eyes shot open as he recognised the voice, but the poor cub cannot move to his safety. He's too busy being used like a fleshjack on Wolf's rapist cock. He sees nothing but his big fluffy pube bush and that thick, veiny rod of meat.
His nose gets scrunched into his bush time and time again, stifling his sense of smell.
Soon, his sense of hearing will fade - hearing nothing but Wolf's desperate moans, and hungry grunts, focused on pleasing the man, if only to end his torment a few seconds earlier before it starts all over again.
"I FUCKING LOVE FUCKING CUBS!" Wolf shouted out, giving absolutely no fucks anymore. He doesn't care if the police will be called on him. He doesn't care if the father finds out and beats him up. He wants to be his real self, if only for a moment.
Daddy unzipped his pants, watching from the bushes. Something tells him that this is the last time he'll ever see his son, so he best make the most of it.
That father? A wolf.
The cub fucker? A wolf.
Aki's fate is sealed. There's no escaping from this.
Wolf drew his head back and howled as he splurged his load deep inside the little boy's mouth. The father started masturbating furiously, his cock gripped with a lust he's never felt before.
"WOLF PRIDE, BABY!"
Sweat falls from his forehead. His whole body heaves with adrenaline. He must've made the whole neighbourhood aware that there's a cub fucker amongst them from his prideful howling and shouting. And the regret he feels? None.
He looks down upon Aki's distraught, exhausted face, and feels nothing but pity for the boy. He relaxes his grip from the well-used cocksleeve- sorry, I mean: cub, and expects Aki to scamper back to his house, crying.
But instead, the cat just continues to wean on the wolf's cock like a milk bottle. 
The leaves get splattered with a heavy dose of cum. Daddy wolf has blown his load, too.
"Oh yeah, now that's a keeper..." Wolf growls out, in his deeper voice. It’s as if realising and accepting his true self has caused more testosterone to circulate within his body.
He'll never let a cub get the tender side of him ever again. He'll show to them what a real beast he is.
A frenzied smile crossed Wolf's face.
"That Alex dude better watch out... I'll be rising high like him soon enough."  It's fair to say that Wolf will take Alex's place anyway. We haven't seen activity from that so-called cub-raper in years! 
Wolf got annoyed by the poorly disguised movement in the bushes.
"Show yourself."
The father finally revealed himself from the bushes, paying no need to a happy Aki who asked daddy what he thinks of 'his new friend'.
Instead, the father simply took Wolf's face in his hands, looking at him with pure lust.
"You're the sexiest cubophile I've ever seen." The man said, his voice full of pride as if Mr. Wolf was his second son.
The two men then engaged into a frenzied, passionate make-out session.
Aki was sitting all alone by himself - feeling very much like a third wheel.
Until a familiar hand touched his back.
"Sweet little Aki... would you like to go in the shed with me?"
His uncle. That good for nothing, creepy pervert. Aki visibly recoiled from his touch. 
"Ugh, no thanks! I've got a new friend now!" 
The uncle looked at his brother making out with a naked wolf, even tugging at his cock while he ranted on about how much he's wanted to 'see it happen to Aki'. 
The uncle looked very confused and crossed his arms.
"Huh, didn't know my brother was gay."
Then, he playfully poked Aki.
"Well, life is full of surprises. I'll be down at the beer garden if you need anything, kiddo. And happy birthday!"
Aki rolled his eyes. As if he'll meet him.
