Everything was going well for the old fox cub, Kyle just came home from school with an A+, his tail wagging like it had a mind of its own as he ran to his father. 
"Dad, Dad!" he calls "Look, I got an A plus." Kyle informs with glee.
"Well done, Kyle!" Felix cheers "I'm very proud of you."
Kyle knew what this meant, a reward he has been waiting a whole year for.


Meanwhile a young fox cub, Robert. Crawled around his room as he played with his run-down firetruck, its paint worn, long before he was born. His ears peeking up and twitching as he heard his big brother come home, Bob babbles to himself excitedly, wanting to play cars with the older cub.


Kyle came into the room and sat in front of his little brother,
"Hey bro." he greets.
"Hewwus!" Robert yips "How is chu?" he asked 
Kyle smiles from ear to ear as best he could with his ears atop his head and all.
"It was good… really good." he tells his sibling.
"Guds," Bob giggles "wanna pwaies?" he ask giddily.
"Sure." Kyle replies.


As the boys play, Felix bakes Kyle some cookies as a reward for getting an A+, this has become a yearly tradition for the third year in a row. he decides to bake Bob some gluten free cookies too as he didn't want to  leave the young cub out. teaching Robert to associate the purple plates and bowls to be his own at a young age was beneficial as Felix didn't want to upset his little tummy.


Kyle makes a few sounds of a car as he pushes the toy vehicle around the playmat, Bob on the other hand was making a siren sound of a police car as he makes it chase Kyle's vehicle, the boys can already smell the cookies and Bob bounces on his behind without his knees leaving the playmat.


Felix calls the boys to the table, Bob was the first to reach the door as he ran on all fours like a feral animal, Kyle follows loosely as he walks like a normal anthro-morph, as he gets to the table, his younger sibling was already in his high chair as their dad buckles the straps.


Kyle takes his seat and starts eating, Bob quite literally mashes his cookies into his mouth.
"Bobby," Felix calls "slow down."
Bob stops eating "Bu cookee." he whimpers.
"I know, but you'll get a stomach ache."
"eas daddie" the young cub replies and eats more slowly.
Kyle finishes his cookies, followed by his brother, the older cub looks at their father who gives him a nod.
"Go get ready, Bobby and I will be in shortly." Felix informs.


Kyle runs to his bedroom, he pulls out the double bed and makes it, ready for the long awaited playtime, the older cub takes his clothes off and waits by the bed. Felix carries Robert into the room, lays him down and takes off all his clothes except the young cub's diaper, he maneuvers his son so he is in a good position. 


"Remember, Kyle. Bobby is a toddler, it will hurt him… alot," The adult fox informs "I already deflowered him last year when I told you what you're reward would be if you got another A plus." he continues "with the training I've been giving him, he will accept you but it will still hurt, so go slow, be gentle and you'll be fine."
"I understand dad." Kyle acknowledges.
"Good, I'll be here to watch and make sure you do it right." Felix informs as he sits down on Kyle's single bed.


Kyle climbs into the double and sees Robert's giddy expansion, he knows what is about to happen to him, Kyle is sure of that. He slides his little brother's diaper aside revealing Robert's cuntboy status, the younger cub whimpers a bit and then smiles.


"Me weadie." he tells his older brother, Kyle nods and pushes his penis deep into the young cub, Bob's head flies back "Bwoda!" he cries.
Kyle looks at their dad who just nods, Kyle turns back to his sibling and rubs his penis inside his brother a few times which started to inflate his knot, in moments they were locked together, Robert takes a sharp breath, besides the pain he felt full, kyle on the other hand, was painting like a wild animal, he continued to pump into his brother, claiming the young cub as his mate
After several hours Kyle ejaculated deep into Robert who felt every rope hit the back of his womb, this brought him over the edge and Robert came around his brother's penis, Felix praised the two and checked how tied the brothers were, Robert immediately screams in pain as the knot was not budging from his spade


"yep, you're stuck good," the adult fox stated" might as well sleep like that" Kyle nodded as their father left and wiped Robert's tears away, after doing so he hugs his little brother and they both fall asleep, Kyle continues to shoot his seed for a while longer, impregnating his sibling as they slept.
