Wyatt has set out to go to a nudist beach with his son, Luke. The two were pudgy bears, Wyatt being in his mid-thirties, with the son being 6 years young. 
Both had brown fur, the father flaunting a bit of muscle along with his fat (the term ‘musclegut’ being best applied to him), but the son was definitely a bit more on the pudgy side. 
As far as appearance goes, they weren't any different from normal bears - although, Wyatt must admit that he feeds his son a bit too much. 
As he sat there, on his towel, the summer sun beating down on him and making him all sweaty and musky - it reminded him of the many nights he spent jacking off to thoughts of his son. 
Even now, as he looks upon Luke playing at the shore, he could simply grab his dick, bust a load quickly to that ass, before licking off the cum himself and pretending he's asleep when his son comes back. 
That's all he's ever done though. As far as Luke knows, Wyatt is just a normal, great father to him - even if he looks a bit too long at him at times, be it when he’s changing, getting in the bath, or when they go to this nudist beach every summer… 

What Wyatt didn't know, however, is that he is not alone with his desires - for the lifeguard was watching afar, looking at the pudgy bear boy himself - and fondling his cock through his shorts. Or should I say, horsecock - for this lifeguard was most certainly well hung with 15 inches of man meat, being 45 years of age, with looks that could kill - and a beard, his body sporting a defined but still pudgy form (due to one too many beers); one could tell that this lifeguard was well past his glory days. 
A horse by no stretch of the imagination, but a complete pervert besides. Even with his pudgy belly, his horsecock still jutted up proudly from the hole of his shorts - and he had to quickly stuff it back inside so he wouldn't get caught by passerbys. When the boy returned to his father, he even spotted his daddy licking his lips then, and that elicited some precum to jut out of his flare, causing a damp pool of precum to appear on his red shorts. 
“Goddamn it,” said Devon, the lifeguard. He was supposed to be watching out for people, but here he was - jerking off to a cute pudgy kid and his-definitely-not-a-pedophile father. 

When Luke walked up to him, Wyatt had to quickly shove all dirty thoughts about his son out of his mind - seeing as his cock was getting more and more erect, and he didn't want his son seeing that (or did he…?).
“Hey dad!”
“Uh, h-hi son,” he replied, his voice wavering with lust. 
Luke looked at him quizzically. 
“What's wrong, daddy?”
Wyatt gulped as he felt his cock plump up. Being called daddy by his son turned him on to no end. 
“Er… Nothing! How about you sit down so I can get some sunscreen on ya?”
“Sure!” Luke smiled, and Wyatt instantly imagined his face covered in his spunk, looking happy about it. 
Wyatt was starting to get horny as he put on the sunscreen on his boy, gently groping him here and there. 
Although, the boy noticed that his father was groping, and he got uncomfortable – whimpering and squirming in his grip. What Wyatt didn’t know, however, is that the boy’s cock was getting hard from it.
“Um, I'm going to go the restroom - daddy.”

Seeing that sweet boy head to the restrooms, Devon knew that this was the perfect time for him to strike. 
Coming down from his stand and, just in time, he managed to stop Luke in his tracks. 
Luke looked uneasy already, intimated by the bulky form of the old horse. 
“Um, h-hello mister.” His eyes widened as they travelled down to see the lifeguard's huge horsecock popping out from the hole of his shorts. Once he knew that the boy was looking at his bulge, Devon picked him up by the neck (squirming) and placed him in the bathroom stall, locking the door behind him. 
Turning to face the boy, he was trembling with fear, but Devon was trembling with lust. 
His horsecock grew so hard that, when he tugged on it to release it free from the confines of his shorts, it ripped them apart and instantly whacked the boy in the face, making him yelp and cry. 
Devon groaned, partly out of that pent up frustration and also from the babbling from the boy. 
“I've got an idea on how to keep your mouth shut…” He said, angling his cock Luke’s mouth. His horsecock was as thick as the boy's throat, and the flare was nearly as big as his face - so this, no doubt, was going to be a tight fit. 
But that is the single most reason why Devon likes boys so much - because they're tight and small. 
He commanded the boy to open his muzzle, and he did so without a word - sobbing and sniffling slightly. 
After all, when you've a huge cock in front of you that belongs to a large old man, you would feel compelled to do everything he asks you to. 
Guiding that thick cock within the slim muzzle was no easy task, but Devon managed eventually. He gripped the boy's throat in his own hands and guided him down that cock while he was perched on the toilet seat (Devon was leaning over him). As Luke was groaning and sobbing, Devon was lost in a cloud of bliss. Nothing feels as tight and soft as a child's throat. It didn't take much effort to get him to like it, neither. 
“Breathe, boy, breathe…” 
As Luke inhaled that cock musk that was plugging his whole throat, Devon let out an unhindered moan of bliss - loving that feel of hot warm breath around his taint. 
“That's a good boy,” he cooed out. 
He retreated his shaft back a couple of inches, and his flare popped out of that constricting muzzle with a loud pop - covered in boy saliva. Devon admired the sight for a moment, seeing it drip down on that cute, tear-ridden face. 
“Repeat after me,” he said, angling his cock up to the cub’s mouth again. 
“I'm daddy's little cockslut.”
Luke blushed as he heard the word ‘daddy’, instantly thinking of his father and the way he has weirdly groped him all his life. 
Devon broke into a smile of delight. 
“Well…?”
Luke gulped, swallowing precum that had collected into his sore throat. 
“I-I'm daddy's cockslut…” He said, barely above a whimper.
“Good, now, speak up this time and repeat after me.”
Devon started to smear his flare on the boy's face, purposely tugging his thick horsecock to spurt more ropes of precum in his cute blushing cheeks, which dripped down his naked pudgy fur. 
“I am a slave for men.”
Luke spoke louder this time, more convicted in his speech:
“I am a slave for men.”
Devon could barely utter words of encouragement to the boy, before his instincts took over - that led to his shaft becoming buried in the boy's throat again, only this time he was way more rough, the boy didn't whimper at all, and he took hold of his head in his hands. 
“Fuck… Fuck yes! Never would've thought I'd meet a gay boy here on the beach who was just born to be a cockslut for daddy!”
Luke felt heat rising to his cheeks again as he thought about his father; his little cock got hard as he thought about glimpses of his daddy’s thick bear cock and the way his father always looked at him, like he was drooling and needing something – but wasn’t able to say it. 
Luke forced his eyes shut. The musk of this horse was so strong for his underdeveloped senses, and that's not to say that the boy is getting sexual feelings for men already! 

Meanwhile, over at the beach, Wyatt was wondering what was taking so long for his son to come back. Ignoring his hard cock for a moment, he decided that it's best to put his son's safety above his predatory desires for once in his life - so he set out to the restrooms himself to find him… 
Upon arriving, the weird slurpy sounds already set his dirty mind off, so he got in a stall door - and was pleasantly surprised to see a glory hole.
Peeping through it, though, he could not believe his eyes. 
His son was deepthroating a horsecock and looking happy about it. He was at risk of exposing himself through his moans, so he had to muffle them with his hand. He crouched down - looking through the hole, and jacked off like a man possessed. 

Devon knew that the father was there. He could hear the slapping of that pathetic dick right beside him. 
“Heya champ,” he said, shoving the last of his horsecock inside the boy's tight, clenching throat - finally bottoming him out. Luke was lost in heaven. He loved being used like this; he was, as his master said, ‘a slut for men’. 
“I hope you don't mind if I blow a load inside your kid. Shame it took you so long to get here, you missed the best bits. He's absolutely craving man cock now.”
Wyatt recognized that voice, it was the lifeguard. He uncovered his mouth to speak, but no words came out. He felt truly defeated. Some other man was breaking in his boy for the first time, and it wasn't him. 
“If you ask me,” the horse continued, “You should've stopped the molesting a while ago. All you needed was to give him your cock and then the kid would go crazy - ugh! Oh yeah, take it, you little bitch!”

Wyatt was sobbing as he jacked off in a frenzy, seeing the man take advantage of his boy, his heavy black balls slapping his chin as he piledrived that thick horsecock in and out the tender throat, Luke's tender lips locked around in like a vice, and making it hard for even Devon - a veteran pedophile - to not blow his load early.
“Stop crying, you wimp. It's not like I'm going to take him all for myself. You can use him after. Just remember that it was horsecock that turned your son into a blubbering bitch whore.”
Squinting his eyes, Wyatt spotted a video camera perched ontop of the stall wall, pointing down at him and placed at an angle - where it would be able to record a top down view of horsecock being shoved in his son again and again… 
“Judging from the silence, I take it you've spotted the camera. Yup, I'm taping this for myself. To keep reminding myself of this sweet, sweet - oh, fuck yeah, take it you whore - tender victory today!”
Then, suddenly a torrent of cum came rushing out of Luke's throat - sheer waves of it crashing down to the floor, then being planted on his face as Devon jerked his cock - giving his newly converted bitch a nice facial. Devon groaned out as he came all over the boy’s face, head tilting backwards and his mind a sea of lust.
Meanwhile, Wyatt orgasmed himself, blasting hot bear cum all over his musclegut body and hand. 
Devon flipped the boy over to sausage his still-spurting cock between those chubby cheeks, covering that with healthy spurts of pedo lifeguard cream too. 
“Take my cream, fuck yes! Take it!
He sighed out happily, wiping his sweat of his brow, his whole body covered in sweat - and whacking Luke's cum-covered face with his semi-hard cock a couple more times for good measure, sealing him as a bitch for men once and for all. 
“Hope you enjoyed the show, cuck.” He tossed a card through the whole, which probably had the horse’s number on it. Wyatt had to wipe off the cum to see it, but it was revealed to be a website address.
“And, when you get home, you’ll probably enjoy the show even more.”
