After such a great game, Karnal had the perfect idea on how to give his son, Ty, his ‘reward’. 
As Ty was heading to the car, Karnal took his hand and turned towards the bathroom stalls instead. 
The son noticed his father's bulging crotch and got the idea, licking his lips for what would be his ‘special father's day’ present.
This wasn't going to be the first time that they had to take a ‘post-game break’, and Ty had switched out from his usual attire for the game to a shirt that has ‘Daddy's Little Tight End’ plastered on it. Well, it rings quite true and definitely gets the father in the moment. 
In truth, Karnal was very proud of his son. He just couldn't stop fucking the sporty kid, and he was always so eager for it. To add, Ty was very cute for his age too - and had garnered a lot of attention from the girls. Despite this, Karnal knew that Ty was his bitch and his alone. The boy briefly glanced at his horse friend, also in the bathroom from the football game, who gave him a smirk in return - then when he noticed his bulky, imposing father beside him - stepped aside. 
Ty hadn't told his father yet, but when he's craving cock throughout the day, the horse boy gives it him - right in one of these stalls. He calls him his ‘big brother’ while he's being dicked down by a superior cock of his age. 
No words were exchanged - only the deep grunts of the father could be heard in the stall, and Ty bending over to remove his trousers and expose that shapely ass to his father. 
Karnal wasted no time in getting his big fatherly cock out, plugging it right into his son's slutty and well-stretched bottom - who gave out whorish moans once the fat tip of his father's cock reached his prostate. Drool fell out of both tigers’ mouth. They've been needing this all day. For the father, looking at his son all sweaty from the football game aroused him to no end. He personally loved it at the end, where Ty was huddled around lots of boys his age, who all gave him big and manly hugs - shoving his cute face in their armpits for a headlock and such. Karnal got sick of fondling his bulging trousers then, and decided enough was enough. It was time to give his son his very special reward! 
Karnal was saving up weeks of cum just for his son, who was now receiving his whole cock raw inside his slutty bottom. It gripped the dad's cock like a vice; a perfect sleeve to fuck and thrust in. 
Meanwhile, the horse kid was in the stall next to the pervy father and son - fingering himself while listening to the deep grunts of the father, who was surely overcome with pleasure right now, while the son moaned on and on. 
To tell the truth, the horse was very jealous. Why didn't his dad do this for Father's Day? 
Though he was mostly top when it came to having sex with another boy his age, the deep manly grunts of the older tiger in the other room flicked his subby switch and he couldn't stop driving his small fingers as deep as he can in his tight boy asshole - his horsecock slapping on his stomach as he imagined his own father succumbing to his desires and properly giving him a good fuck for father's day. 
“Please daddy, open my ass…” He moaned out, his mind overcome with sex and envy for the couple in the other room. He didn't even need to touch his cock. As he heard those manly groans become louder and deeper, his young cock throbbed harder and harder until an explosive torrent of hot boy cum exploded all over his cute face and smooth body. 
Deep down, he knew it wasn't enough - he needed the real thing. He craved real man cock inside him. 
The tiger and his son was oblivious to the masturbating boy in the stall beside them - so when he came rushing in mid-fuck, Karnal was assuming the worst. He was, until he turned around to see the cub in question stark naked with an impressive leaking horsecock leaking between his legs. Karnal gulped as his cock throbbed harder in his son, looking at this sexy colt. 
“Please sir… Fuck me!” He said, loud and clear. 
Karnal was torn. On one hand, he really wants to give this boy what he craves for on this special day, but on the other hand, he was not finished with his slutty son.
His cock decided that he has passed the point of no return, the part where you can't just simply ‘pull out’, you have to cum inside the hole, no matter what. 
“How about you fuck me instead, kid? Your cock looks like it needs it.” Karnal said, acknowledging the boy with a thrust in his hips that made Ty moan out again. 
The boy put on a brave face as he tried to win the father over, eager to get that alpha cock inside of him. 
“Heh, I know Ty is such a whore, sir. He always moans for cock. But I want it now!”
Another voice entered the stall, deeper and far more baritone than the tiger's. 
“I can take care of your needs, boy.”
The colt turned around to see the smirking face of his handsome wolf coach - who had brown fur and a needy uncut cock unzipped from his fly. It was the same coach who was from the game, Karnal noticed. The more the merrier! 
“Get that slutty boy ass on my cock, then.” He grunted out again, taking off his sweat to reveal a sweaty and muscular body. The hair on his armpits made Karnal gulp as he felt a musk far stronger than his fill up the room. 
The horse cub wasted no time on bouncing on that coach cock, eagerly bending over so the coach could take him by the hips and drive forward his needy cock in the tight slick insides of a ‘boy-cunt’, as he liked to call it. 
He moaned out and kissed the horse kid on the neck, sending him into shivers and making his horsecock all nice and hard - that was rubbing between Karnal’s shapely cheeks. 
The tiger stopped his maniacal thrusting in his own son for a second, to thrust his ass on the boy's long cock, making him feel all dirty and like a true perv once he felt that young horsecock enter his backside. 
“Ooh, damn, that feels good… Fuck me hard, kid.”
It was a bit difficult for the boy to focus, especially when his coach was fucking him from behind with his thick cock and sending his body into full slut mode. Yet, at the same time, his cock responded very well to be inside a man's asshole. This wasn't like the boys he fucked, where he felt like he was the dominant one - for no matter how hard he thrusts, the truth is: Ty’s ‘Big Brother’ is sandwiched between two very powerful, muscular and older men who are both eager to fill in the role of being his father for Father's Day. Whether it being massaging his needy boy cock with a warm manly ass riding up and down on it, or getting fat mature cock shoved in him to send his body into overdrive, he loved it all - and he soon found himself reaching the most amazing orgasm in his life, creaming Karnal’s ass with thick batches of young virile horse cum - popping out his horsecock to see it leak all over the floor. 
“God, you fuck good, kid. Maybe you'll be like one of us someday: fucking your own son, or being like this pervy coach…”
Karnal resumed his thrusting into his son, who had to lean against the wall for backup, as his father took him by the hips and pounded him deep and hard. In a matter of seconds, with a heavy grunt, he had exploded all his pent up tiger seed in his tight son's asshole yet again and basked in the afterglow. 
At the same time, the coach was totally getting off on fucking one of his students - praising him and telling how good he was at the game while sending his small tight asshole into shock with thick uncut cock. The coach is having the best day of his life right now, 
“So that's why you and Ty take so long at the showers. I guess Ty is such a cock whore that even being fucked by his dad isn't enough!”
More neck kissing and deep moans from the wolf made the colt very submissive and whimpery.
“But you… You need to be fucked just as good, too. Do you want your coach’s cream, kid? His jizz right up in your slutty cunt?”
He breathed out, 
“Yes! Yes! Please breed me like a proper kid should bes bred!”
With a deep gurgling cry, the brown wolf jizzed all in that tight boy cunt just like he promised! Some of it leaked out from the side of his well-fucked arse, but most of it was bred deep in his belly - filling up his sexy body with just the man cum that he craves. 
All four males collapsed into an amazing afterglow together, both Karnal and the coach exchanging numbers for ‘business reasons’, while feeling up the bodies of the boy's that they had just fucked vigorously. The boys were very content with their filling of man semen. 
This was certainly a fun and different way of celebrating Father's Day…
