Simba arose to his paws, seemingly hypnotised by his son's sexy stance before him. He could clearly see the cubs tender butt cheeks, wiggling around, just waiting to be picked. He approached his son, eager to show him who was boss. After all, he couldn't have all the lionesses fucking Kion all day. 
Simba took in a deep, lungful breath of his son's rear, taking his cubbish, youthful scent. His mouth practically salivated at such an innocent, loving sent, so much so that he could help it. He just had to have a taste. The lion king felt his son's soft, slightly dirty rectal fur brush across his rough comb-like tongue. Traces of his son's previous sexual encounters with his mother and sister had dribbled down there, giving Simba a taste of Kiara and Nala's love essence. Oh, how he was turned on right now! Kion seemed to be so too, if his fully erect little pecker beneath Simba's tongue was anything to believe.
"Taste me, daddy!" Kion giggled, his juvenile, sweet voice only turning his father more and more on. Simba couldn't resist anymore. He needed Kion's boy pussy. His tongue shot into his son's arse, tasting the warm, succulent, innocent meat within. Kion responded with a series of growls, his claws protruding into the dirt as he raked through his erotic feelings, bursting through his body. "OH YES!!!" 
The squelching sound of Simba's tongue lapping up Kion's insides brought Nala's heated feeling back to her now tired body. Looking over to her left, she saw her daughter still unconscious from her violent, euphoric fuck her father had given her. The young lioness cub's pussy stretched and torn by such a powerful fucking, now oozed with the same gloop that had created her all those months ago. 
Coming too, Kiara felt her body continue to tremble, releasing small gushes of her love's mixture from her deflowered pussy. She couldn't feel anything more than her father's love for her, his lust for her. Looking up, she felt her mother's head rest on top of hers. staring down with a lustful, wanting gaze. Kiara tried to speak in between her orgasmic groans, only to be silenced by her mother's tongue, slithering into contact with her own. The two feline's organs softly and slowly caressed one another, bringing both lionesses to a state of heightened sexual tension, unlike either which had ever seen. Both became breathless, fighting the will to continue their lustful snog just to gasp for air. 
After a few seconds of heavy, intrigued, sloppy snogging, Nala pulled out of her daughter's exhausted mouth, both of them gasping for air. Both lionesses stared at each other, knowing where both of them wished to take this erotic scene. Kiara craned her neck upward at her mother, who's rear slowly wiggling down, connecting with her daughter's below her.
"Mummy?" The young lioness cub asked, feeling her mother's sloppy, cum soaked pussy wiggling into hers.
"Shh, little cub." Nala calmly smirked down at her daughter, trying to feel for her daughter's pussy with her own. "Let mummy dominate you." Nala licked her daughter's nape, forcing the young lioness cub's body to squeal in pure pleasure, wiggling uncontrollably at her mother's affectionate, lustful movements forced their plumped pussies together, with Nala's grasping over Kiara's locking them in place.
At the same time, Simba pulled his tongue away from Kion's now well-lubricated arse. The young lion cub looked back at his father as the building pleasure in his body halted its growth. His relaxed, longing posture suddenly found itself stiffen, shocked at such a lack of energy. He looked back at his father only to be pushed forward, his arse presenting itself as Simba pounced on to his son. Kion felt so small underneath him, his head barely sticking out from under his father' mane.
"Ready for a real fuck?" Simba smirked, locking muzzles with his son. Without warning, the lion king thrust forward, forcing his massive, throbbing dick into his son's awaiting arse. As he entered, Simba brushed his tongue into Kion's mouth, slithering into the young male cub's orifices from both ends of his body. 
Kion's growls of pleasure and pain were smothered by his father's invading tongue, slurping and sliding across his own as they performed their complicated, longing dance. The young lion cub could feel his rectum being stretched to all new levels as his father's flesh piercing cock slammed further and further into his body. Strangely though, kion could help but feel shots of pleasure shoot through his body, only building as their tongues caressed one another, feeling each other's teeth rubbing against each other. 
A few minutes later, Simba let go of Kion's muzzle, slithering his tongue out of his son's. as he did, he increased the tempo of his thrusts, forcing Kion to roar with lustful pleasure as he felt his father's cock slid further and further into his body.

"YES, DADDY!!!" Kion screamed barely regaining control of his body. "Fuck me hard daddy!" Simba obeyed his son's wishes, struggling himself to remain in control of his bodily functions. His cock oh so wanted its release inside his young son. To spew his seed all in his boys awaiting anus. But no! Not yet! 
"Hmm!" Simba groaned, feeling his impending orgasm fighting back at him. "That's it, my little fuck toy!" He continued to pound into Kion's arse, his large, cum-filled balls slapping against his son's hindquarters forcing his own tiny, underdeveloped balls slamming across the ground, his small, recently used penis spewing its seed all over the floor, providing a trial of lubricant for his body. Kion roared at his release, loving the feeling of his father fucking him so tightly.
Meanwhile, Nala continued to fuck Kiara, grinding her pussy lips over her daughter's. She felt her orgasm rapidly approaching, the feeling of her daughter's used sloppy pussy exchanging the love mixture of her, Simba and Kion mixing between the two lionesses, building in a vacuum between the two lionesses' pouring mounds, their urges growing and growing until.

"Ahh!" Kiara gave way, her small orgasm squirting her essence into her mother's awaiting pussy. The young lioness cub shot her head up, meeting her mother's neck as Nala lost control of her thrusts. The dominant lioness exploded, causing the vacuum between the two to fall, squirting their love juices all over the place. Both lionesses roared before coming down from their orgasmic highs, cuddling up to one another.
Upon hearing his mate and daughter's roar, Simba stared down at his son, who only added his voice to the orchestral groan of lust. The lion cub's arse was biting down on his dick, milking it of every drop of his father's cum, longing for him to soak his insides. Simba could barely contain himself any longer and, taking a deep breath, shot himself further into his son, ripping through his body like a caw through the skin of prey. 
Losing control, the lion king roared to the heavens, joining his family in their orgasmic chant. His seed soaked his son's insides, filling every crevice of him with pure lust, until there was o room left. Simba shot out of Kion under the pressure building, causing his remaining cum to gush over his son's rear, seeping from his recently deflowered rectum. 
Kion instantly fell to the ground, breathless and worn. Upon hitting the floor, he quickly fell asleep, his father's cum acting as a comforting blanket for him. Kiara joined him, crawling up to her brother until she collapsed by is side, a trail of cum leaking from her pussy as she did so. 
Simba flopped down beside his son, still leaking cum as he shook from such erotic, dirty fucking. Nala breathlessly flopped beside her mate snuggling up to him as their cubs snuggled inwards. She stared her king directly in his brown, longing eyes.
"They're already incredible little sluts, aren't they." She smirked up at Simba, who looked down at her and their cubs, all coated in cum. He still couldn't believe what they had done but was grateful. No one had to hide anything anymore. They are a family after all, and families share everything, even their sexual urges.
After all, they were one...
Always...
