Kion froze in the presence of his father, his eyes focused on the bulging, erect penis dangling before him, sore with pressure and a need of release. Simba, smirking madly, slowly re-approached his son, returning to his plump, cum filled rear. His rough adult tongue slid across the lion's rim, sending even more shivers through Kion's spine. The tip of his tongue occasionally entering his son's anus, taking a trickle of honey badger cum with it. 
"Ohh! Daddy!!" Kion cooed. He couldn't believe what was happening. Here he was with his father rimming him like a pro. His small, feline penis shot out its cum soaked sheath once more, drooling and dripping onto the cum coated leafy floor. 
By now, Bunga, Timon and Pumbaa had left, leaving the lion father and son to their 'lessons'. Simba took their absence to his advantage and began to lick further into his son causing Kion to moan and roar louder and louder. The Lion king eventually left his son's arsehole be, for a little while, and moved down to his recovering, yet plump balls. He had looked at them regularly through his life, ever since his mother had brought the cub home for the first time. The fact they would produce the next generation of lions, the next pussies and dicks to suck and fuck, had always made Simba's dick harden, even spurt. 
Every time Kion left the lair, Simba would stare at his son's nether regions hoping one day he would be able to taste them, have them. Now, that day was here. He took one of his son's balls in his large predator mouth, suckling the furry plump with severe ferocity. This caused Kion to roar with pleasure. The small lion cub collapsed to the cum ridden floor, his rear still shot up to the sky as his father continued to violate his testicles. Simba saw his son's uncomfortable posture and decided to let go of his balls. With this, Kion flopped to the ground, too exhausted to continue further, his body shaking with paralysing pleasure.
As his son lay on the ground before him Simba placed his paws on his shoulders, forcing his son onto his back, revealing the tasty, fleshy package nestled below in all its glory. The cub's under-fur was covered in a mixture of spunk and bodily fluids, only adding to the erotic scene. Simba continued to suckle on his son's now bare balls. His tongue caressing the short, furry coating surrounding them. He could feel the small amount of life giving cum bubbling away within, waiting to be released. His own hard gigantic cock throbbed behind him, begging for some relief. He knew he didn't have long.
Releasing kion' balls form is grasp, Simba removed his paws from his knackered son, allowing the lion cub to move once more. He rose to his paws, looking down at his son's tired, still body.
"Get up!" Simba ordered. Kion obeyed his father's harsh, dominant demands. He didn't mind though. He was loving it. Finally, his father was playing with him. He had noticed his father's 'attraction' to him and would provide the occasional show to him as he left the lair to join the guard, rising his tail and butt cheeks within view of his horny father. He watched as his father and mother fucked, jerking his own little cock as he did so. Bunga and Kion had made this a habit for a while until even that became too boring for them hence today's events.
He turned to face away from his father, presenting his well-lubricated rear up to his waiting father. Simba took no time in taking advantage of this and quickly mounted his son. His large, prominent dick resting alongside Kion's still tender buttocks. He gave his son a few slow, lustful humps, forcing his dick to stroke through his son's fur, past his tail and over the hot, cum soaked him of his arse. Kion groaned at this, his body far too excited to contain itself.
"Yes daddy!!" The lion cub growled licking his lips. "Take me!!! Take my arse as yours!!" How could Simba refuse such demands? His thrust grew with every second, Kion's erotic groans and moans only enticing his father on further. Simba felt his son's back brush through his chest mane the heat building up with every second. With one final thrust, he found his son's rectum. This was it!
Both lions clenched their teeth as Simba entered his son. His penis burying its way into Kion's insides squishing and ripping through the lion cub's rectum. Simba growled at the feeling of his dick in his son. His arse bit onto his dick, milking it of its seed. The same seed that only a year or so prior, had created it. 
"AHH! KION!!!" The lion roared, pumping his dick into his son. "You're so tight!!" He continued fucking his son, his large, cum filled balls slapping against his son's bare arse, the sound of these collisions forming the bass of their lustful song. Their cries of erotic pleasure had become the chorus and the squelching, oozing sound of his dock seeding Kion was the percussion. 
"Yes daddy!" Kion responded, his rear legs tingling with pure lust for his father. All he could feel with the near rupturing penis sliding in and out of his arsehole, plunging deeper and deeper into his body, stretching his insides with every thrust. "Take your son!!! Teach me my lesson!!!" His screams only enticed Simba on further, his balls rumbling with the urge to fire.
This went on for some time, both lions gritting their jaws as their orgasms grew, until it was too late...
"AAAAHHHHHHHHHHHHH!" Simba finally blew his load. Gallons upon gallons of cum erupted from his balls nearly ripping them from their cords, pumping directly int his long, sore dick until it poured into his son's arsehole. It only took a few seconds for the lion cub's tender arse to fill, throwing his daddy's cock out of him. Cum gushed from the opened rectum, gushing out like a creamy white waterfall. 
"DADDDDDDYYYYY!!!!" Kion' balls clawed through their own ejaculation, spewing some of his seed onto the ground. He rose his head, feeling the immensely hot mane of his father. As his father's cock exploded out of him Kion shot out from underneath his father, who collapsed on the ground, his cock still twitching, gushing his seed all over the floor.
"Wow!" Simba gasped, still catching his breath from such a good fuck. "You're just as good as your sister!" He remembered his times with Kiara, ever since she was a small cub she would suck upon his large cock until she was able to fit his cock in her. All of this was part of her 'queen lessons. His mind flashed through such memories as he rolled over, allowing his still spurting penis to face the sky. His own spunk shot over his body, tangling within his mane fur. 
Kion, now recovered from being fucked so well turned to see his father's dick, still pulsing with semen. An idea brushed through the lion cub's mind, a filthy one. He slowly crept up to his dreaming father, pouncing onto his chest from seemingly out of nowhere.
"My turn, daddy." He smirked up at his father before licking the cum-laden fur beneath him. Watching his son lick the cum out of his fur sent waves of pleasure through Simba's groins once more, forcing his dick to harden again. The cub turned, showing his cum soaked, stretched arse to his new mate. Kion stared at his father's welling penis, eager to take a mouthful. He clutched the meat with his mouth, giving it a series of affectionate licks as he did so. Simba's moans were more than enough to convince Kion to carry on, tasting his father's spunk. 
"That's it, son." Simba purred, feeling his son's tongue caress the still erect barbs on his penis. "Show daddy what you've learned!" Kion continued to suck, wiping and sucking off all evidence of Simba's ejaculate. Kion smiled at his father's twisted words before letting go of his hardened dick.
The lion cub turned around once more slowly crawling up his father's body, grinning widely with every step. As he approached his father's face, he locked their muzzles together his small cum-dripping tongue connecting with Simba's, dumping a fresh load of Simba's cum into his own mouth. Simba loved the taste of his own seed, but coming from his own son's mouth, delightful. 
Departing from their snog, Kion pounced over his father's muzzle, placing his own hard yet much smaller cock at Simba's muzzle. Simba knew what Kion wanted, what he needed. He grasped his son's dick and began to suck.
"That's it daddy!" Kion responded, feeling his father's tongue tickle the small, painfully sensitive barbs. He could feel his balls glowing with the production of even more semen, ready to spew into his father. Simba seemingly could sense it too, removing his muzzle from Kion's penis and instead suckling o his balls once more.
After a little while longer of this, Kion lept off his father's face. Turning around once more, to face the lion king, Kion smirked. He knew what he wanted, to finish off this exciting day. 
"Turn around!" Kion ordered, a certain, manly tone erupting from his mouth. "Let me see your lovely rectum, daddy." Simba obeyed his son's demands, showing his son his large, loose rim of his buttocks. He moved his tail to the side as he lay down, allowing Kion to slip around him and mount his father.
"Ready for the fuck of a lifetime?" Kion whispered, his small, rock hard penis nestling at Simba's entrance. Simba prepared himself, steadying his paws, ready for the pouncing of his rectum hungry son. He shook his head, signalling his readiness. 
With that, Kion dived into his father's rectum, his mall, hungry penis sliding into the wide, open spaces that Simba's insides provided. Just the feeling of being inside of his father for the first time was erotic for Kion. He didn't actually care he wasn't feeling anything, at least at first. Simba couldn't even feel Kion's dick at all, only his balls slamming against his tail with each of his manic thrusts. To counter this, the lion squeezed his rear muscles, crushing into Kion's dick like the teeth of a lion's mouth. 
"OH YES!" Both felines groaned in unison as Kion's thrusting sent them both back into a state of lustful groaning. Neither couldn't believe what as happening and how the day had played out. They wanted to do this forever and ever, especially Kion. He loved fucking his dad, feeling his small balls slamming into his father's large, bulging load beneath them. 
"That's it son!" Simba screamed raising his head to the heavens. "Fuck your daddy! Fill me with your cream!" Simba had all but lost it. He remembered when he had fucked his own father, not long before he died. He remembered the bulging feeling spreading through his body, the need to release all his love for his father. Kion must have been going through a similar feeling, as his thrusts became more dominant. He was nearly breaking point and Simba was prepared to receive his own son's cum.
"Hevi Ka-!!!" Kion couldn't even finish his signature catchphrase as his dick erupted inside his father, spewing ropes upon ropes of cum into the older lion's intestines. Simba roared out his son's release, creating a duet of lovemaking between the two lions. Kion's back legs spasmed as he tried to deposit as much cum in his father as possible, his balls squeezed of all their juices.
"YES KION!!" Simba roared, peaking his own orgasm. His balls once more spilt their seed out not the floor, providing even more lubrication between him and the floor. This allowed Kion to slip into him further, depositing even more of his precious, tasty cum deep in his father.
As the two lion's orgasms settled, Kion collapsed on his father's back, s penis shooting out of the plump anus it had emptied into to. Both father and son revealed in the heat of each other's bodies, and f the cum that nestled in both their rears. They had done it! They had fucked each other to the Great Kings and back. Mufasa would have been proud of them, both of them.
In time, Simba shook Kion off of him. He had learnt so much in such a small amount of time. There wasn't much more that the older lion could teach his son, but there was one thing he could do. He noticed two trails of cum running along the leafy ground, one of his own cum and one of Kion's. He took a pawful of each before running both together, infusing father and son's spunk into one. 
He then approached knackered, lustfully dazed Kion, who could only stare at his father, examining his fit, sexy body. The older lion raised one of his cum soaked as, wiping it across his son's forehead, leaving a trail of their mix cum on him. He then the other paw load on his own forehead, before flopping down beside his son, cuddling up to his new sexual plaything. 
"We are one, my little sex toy!" Simba smirked, grabbing his son's warm cum soaked body. Kion just smirked at his father, giving him an affectionate lick across his mane filled chest. The two lions huddled up together, falling asleep in a sea of cum, made of theirs, but also Bunga's Timon's and Pumbaa's.
One thing was for sure though. They were very much one, and for many months after this day, they would sneak off to a secluded spot together, to infuse this closely guarded bond they had formed.
For the son was very much as dirty as the father. But they didn't care. They were one and would fuck each other for days if they could.
And they would...
