Alex certainly loved his clients, otherwise, being a doctor was a mundane job. 
Quite often boys had come in with queries about their butts, most likely a result of their fathers using them to their fullest potential…
Alex had always wanted to do a certain something to a boy: rim him - so when he always inspected them, it was a struggle not to slurp up the dad cum oozing from those still-tight little holes.
Alex's line of work was most unique, that goes without saying. Dubbed the “boy doctor”, Alex knew just how to diagnose and ‘cure’ his patients. You see, though the wives and women don't know, boys get lots of use from their fathers when they're out. Be it plugging their sons’ tight hole with a thick piece of daddy meat, spurting a load inside the tight ass to take off the edge a bit, or rimming - to make the boy all giddy and happy - fathers around the world were most grateful to these “boy doctors” for their frequent checkups. They inspected the boy's hole very carefully, searching for signs of tearing, any infections, all to ensure that the healthy relationship between father and son could continue. This ‘healthy relationship’ being the father's cumdump for when the wife is out. 

Today was just like any other, Alex thought, where it would involve many checkups and jacking off to the images he had burned in his head of boy holes and cock.
That is, until a red skunk came in, looking all shy and conscious of himself. Alex flashed him a smile while his eyes was busy looking over those slender hips and the very sexy stature of the boy. He groped himself, his paw in his work trousers - handling his big, throbbing man package for a while - before the boy looked up, and asked him how his day was going. 
Well, that was unexpected. Such a pleasant and kind boy! 
“It's going well, thank you,” he said, while flicking up a spreadsheet to assess the boy. 
“Your name?” Alex asked. 
Upon seeing the handsome features of the wolf yet again, the skunk blushed and fumbled with his fingers. 
“U-Uhm, its Travis, sir.”
“And how big is your daddy's cock?”
The question instantly threw him off a bit, making him squirm and struggle to maintain eye contact with Alex. 
“Um, I'm not sure…” 
“Your father's penis. Surely you've seen it at some point?”
He slowly shook his head, like it's something he has to be ashamed about. 
Alex leaned back in his seat. 
“Oh, well, we can't be having that.”
He continued, one paw rolling his heavy furry balls in his grip, the other arm - slack beside the chair. 
“Why did you come here then?”
Travis’s eyes widened when he saw Alex's bulge, like it was a dream nearly coming true for him - to see a penis. Only when Alex asked him a question, did he avert his gaze from the sizable package below - to those purple, warm eyes. 
“My daddy told me to get checked up.”
Alex nodded slowly. 
“I see. Travis, come over here.”
His other paw beckoned the cute skunk boy forward, and he got up out of his chair shakily - as if struggling to walk from the excitement and thrill of another man's touch. 
Once he did, Alex spun him around, and told him to bend over - so the boy's behind was facing him at eye-level. 
Alex slowly dropped the boy's shorts, feeling the tight rump and loving the feel and texture of the fluffy tail he had to pull back, as well as the young fur itself. 
Alex broke the silence in the room. 
“How old are you, Travis?”
“13, sir.”
Alex tutted once he heard his reply, stopping his paw rubbing of the ass a bit to rub his stubble on the fur - making Travis all giddy and tremble with good feeling; the electric touch of another man using him to his advantage. 
Alex's warm breath sent shivers down his spine, breathing over his tight pink boy hole as he talked, lubing it up with his spit. 
“Umphh, not very -slurp- good, that a boy of -sclorp- of thirteen summers hasn't seen his -slorp- daddy's cock yet.”
Alex pulled back from his gentle rimming with only a string of saliva attaching the distance between his stubble and boy's ass. 
Wolves produce so much spit (that's lube) for boys. 
“But we will rectify that, won't we?”
Alex could practically hear the elated delight in Travis’s voice when he got his doctor's approval to take his virginity. 
“Thank you so much, sir! My daddy never uses me because my mummy is in the house all the time…”
Alex hugged the boy from behind, and unbuttoned his shirt - making his muscular chest rub against the small, slender back of the boy (he is only 3"2 tall). 
“Now, while I'm giving you a nice rimjob for that tender, tight ass of yours, you need to take my cock down to the root - understand?”
“Yes, sir!”
Alex released his recliner on his chair, and leant back, taking the boy with him - so they were 69ing.
If it wasn't for the obscene bulge in his work trousers, Travis’s nose would've picked up on the musky scent of the wolf's riled-up-and-ready cock anyway. 
“Unzip your present, Travis. Your father knows you need it.”
As Travis was eagerly unwrapping what would be the first and best cock he ever gets to suck in his life, Alex had his head buried in Travis’s rear - nourishing and eating out that tender hole with his thick wolf tongue. 
The boy's musk was soft, but very much there, smelling like a refreshing fragrance.
Alex was very pleased that the boy was healthy and tasty on the inside - all it lacked was the semen of an older man to fill in the space. 
And, judging by how tight and firm this boy's rear was, it would not prove to be difficult. Infact, one could say it could be too easy to blow inside this child - with how warm and tight he felt around Alex's tongue. 
Meanwhile, the boy was being sent into shivers all over from his doctor's tongue licking and being sent deep into his tight insides. 
It was a struggle to keep his hands from shaking, but eventually Travis managed to pull out Alex's massive cock - which whacked him on the face, precum dripping down from the tip. Travis licked up the traces of precum on his lips, then opened his mouth, and clenched his soft lips tightly around the thick canine length. 
He could hear Alex's deep moaning, his hot breath reaching deep into his depths as his tongue lavished around and inside his ass, making him all excited and ready for cock. 
In just one swallow, although Travis didn't realize it, he took all of Alex's 9 inch canine cock down his muzzle, Travis’s own muzzle lost in Alex's fly - those furry pubes poking out from the side, which tickled Travis’s nose and forced him to inhale the manly musk coming from them, as a sign of a wolf's virility. 
Alex stopped his deep rimming, his tongue slick with boy ass juices as it popped out, to give his patient words of encouragement. 
“Fuck yeah, boy, you take all of my cock down.”
Alex used a paw to keep Travis’s head down for food, pressing his nose down onto his fat, musky sheath. 
Much to his surprise, Alex even felt the boy's tongue making its way over his musky, furry and big black balls, ripe and full with cum to give to his patient: all in preparation to make him a slave for his father. 
“Your daddy is going to love that tongue going over the cock that made you, boy.”
Travis just meeped and winced his eyes in response, his vision growing hazy from the great cloud of musk that came from the wolf's crotch. 
Alex released his grip and said: “you can pull up if you want to.”
As soon as Travis heard that, Alex went crazy from those tight boyish lips gripping around his cock tightly as he backed up 9 inches of canine man meat in his tight cub throat, releasing it with a pop and covered in boyslut slime. 
“Fuck,” Alex said, under his breath. 
Once he saw Travis’s exasperated, cute face again though, he could not hold back - nor give the boy enough chance to breathe - as he held his small head in his hands and made out with him furiously.
Once their two mouths locked with each other, Alex knew that this is going to be the best patient he has in a while. 
He was blown away himself, breaking away from the kiss, with love in his eyes, only to delve back deep into the boy's ass - with Travis taking Alex’s very-throbbing cock to the root again. 
The two resumed their eager, passionate sex for each other, with Alex nearing his limit - spraying so much precum down the boy's throat that it is surprising he didn't cough it up. After all, I suppose anything will be hard to cough up when you have a canine cock stretching a slim, young muzzle to its very fullest. 
Alex could feel his cock reaching its climax, cum gurgling through his fat balls, reaching his tapering penis - eager to spill his milk. And spill his milk he did, his face contorted in pleasure and groans as heavy and dominant as a werewolf itself. 
“Take it… Take all my previous wolf seed, boy!”
The fact that Alex could practically hear Travis swallowing down his cum, made him more horny to fill the boy's mouth with seed - of course, with being deep in his ass, Alex also loved the feel of the boy's moistness and tightness around his tongue, flexing that ring as much as he could with his tongue. But none of the other patients compared to Travis’s warm muzzle, it was like a blanket of warmth - and he was a very happy man right now. 
Once Travis retreated his muzzle from that cock with a look of pure satisfaction on his face, Alex knew that the boy was cut out for being a slave to his daddy. 

“Thanks for draining my balls, kid,” Alex said with a huff, still a little bit out of his zone (he didn't even notice the boy grinding his small little ass on his still-hard cock).
“You're welcome, sir. Put your penis in me now.”
Alex smiled brightly upon hearing that, and patted the boy on the head. 
“That's something for your dad to do. Remember, as a son, he needs to take your virginity.”
Travis nodded, “Right!” Just before heading out, he gave one more look to the exasperated Alex - a look of contentment, smiled - and went on his way. 
While he was on his way home, all he could think about was how hard his daddy was going to fuck him.
