Ron reclined on his lounge and watched his 10 year old son David towel off after his quick swim, of particular interest was the boys’ rear pleasantly filling out his tight powder blue speedos.  The tiger growled in pleasure as he gripped his own sheath through his swim trunks.

"Come here, David," he said with a grin.

Knowing exactly what his father intended to do, David padded over, making sure to add a suggestive wiggle into his stride.  When he reached his father, he leaned over to deeply kiss the older tiger.

After a few moments, David broke the kiss, "How do you want me?" He asked.

"Use your mouth," replied Ron, "If you're good enough, I'll give you a proper mounting."

With a smile, David began to kiss his father’s chest as he slowly worked his way down to the swim trunks.  Fishing out the drawstring with his teeth, David gently pulled on one end until the knot was undone.

With the help of his father, he carefully removed and tossed aside the article of clothing before he began to work on his prize.  Ron was average in size and that suited both his wife and David, it took a few gentle strokes before the barbed penis peaked through the sheath.

Taking the member in his mouth, David began to suckle while bobbing his head up and down the shaft.  Ron’s size meant that he had no problems filling either of his son’s willing holes and judging David’s enthusiastic bobbing, the cub was both a willing and eager participant in the incestuous activities.

With his cock inside the warm mouth of his son, Ron let out a low moan.  “Yeah, boy.  Just like that.”

Spurred on by the encouragement, David made the effort to take his father’s penis down to the base, making sure that it was adequately lubricated for later when it would be going under his tail.

Ron watched the erotic sight of his son pleasuring him with his mouth, he knew that with such a talented cocksucker, his fuse would be short.  Taking a firm grip at the base of his cock, partially to prevent his son from going too deep and partially because he knew that he would cum soon, Ron rubbed the back of David’s head, encouraging him to go faster.

All too happy to continue the task at hand, David felt his father’s cock start to twitch under his ministrations.  Taking the shaft from his mouth and gently stroking it, David asked “Can you cum in my mouth, Daddy?  I want to taste your cum before you fuck me.”

Ron didn’t answer, he just gently pushed his son’s muzzle over his cock and started to carefully hump.  From experience, David knew that this was the signal that his father intended to cum in his mouth.

It only took a few humps before the pleasure became too much for Ron.  With a groan he forced his son’s muzzle down so that David’s nose was brushing up against his fingers as he flooded the young tiger’s mouth with his cum.

“Oh, yeah!” groaned Ron as he looked into his son's eyes, the boy’s cheeks swelling with the cum that was coming faster than the cub could swallow, “Of all your friends, you’re my favourite little cocksucker.”

David kept suckling until the flow of ejaculate tapered off and he could swallow the excess.  He knew that his father liked it when his friends came over. On more than one occasion, a weekend ‘Camping’ in the backyard turned into an all-night threesome that saw two slightly sore but happy cubs greet the dawn.

Pulling his father’s cock from the warmth of his muzzle and giving it a few tender strokes, David asked “Are you going to fuck me now, Daddy?”

Ron looked down past his son’s tender stroking paws, past the soft and creamy white fur of his belly and to the swelling in the crouch powder blue speedos.  “I’m going to be balls deep in your tight little cub ass, boy.”

Helping David out of the speedos, Ron took a moment to gently stroke his son’s immature cock from its sheath.  At only 4 inches, the boy will have to wait until puberty to see how he would compare to his father.

David looked at his father's cock before him, imagining it penetrating him as he sat on his father's lap.  The pleasure that he knew it would bring as he rocked back and forth while his father kneaded his backside and held him close, the kind words of his father being whispered in his ear as they shared their mutual pleasure.

It was a surprise to David as Ron roughly turned the cub around and forced his face towards the end of the lounge.  “You did a good job sucking my cock, boy.”  he growled, “So now you’re going to get a proper mounting.”

Ron repositioned himself so that his cock was nudging itself up against his son’s anus, he wasn’t surprised that the cub had pre-lubed himself with a water resistant gel.  David was always ready to please.

Taking a moment to admire how his cock sat between the cubs buttocks he gripped his son’s hips and pulled the cub back ever so slightly.  David enjoyed resisting his father’s cock for a second before his well-trained ass allowed the intruder inside.

Ron moaned in pure pleasure as he slowly sank his length into the tight confines of his son, by taking his time, he allowed David time to adjust to having a cock in his ass.  It took a few years of practice, but David knew what was expected of him and thanks to the ‘peculiar’ lifestyle of his classmates and their families, he was not the only one.

“Oh, Daddy.” Said David with a gasp, “I'm so full.”

From any other person, such a line would sound cheesy but Ron knew that his young son enjoyed having a cock up his ass.  In time with his thrusting, Ron said, “Your ass, is just, as tight, as when, I first fucked you!”

“What about Dusty?” asked David, gasping after every one of his father’s powerful thrusts, “How’s his ass?”

Ron had enjoyed fucking David’s friend Dustin on several occasions, the otter boy’s slim physique and small frame made him a perfectly sized plaything for the adult tiger.  The boy having a water tight ass and no qualms about sex was merely a bonus.

Ron couldn’t bring himself to lie to his son, “He’s tighter than you,” he said between thrusts, “But you’re more fun to fuck.”

The sexual relationship between David and Dustin had not progressed passed the oral sex phase.  Each cub was very eager to suck on his friend's cock and the sight of the two cubs intertwined in oral pleasures had provided much fuel for Ron’s masturbation fantasies.

A shiver of pleasure ran through David, his father’s approval meant a lot to the cub, the shiver also caused the boy's ass to momentarily tighten up, transferring pleasure to Ron.  “I'm going to make you fuck Dusty” said Ron, “And while you fuck him, I’m going to be fucking you.”

As his father’s words registered in his mind, David felt his father shift position.  The shift was followed by the cub feeling the barbed feline cock push that little bit deeper, right into the cubs pleasure centre.

“What else are you going to do, Daddy?” cried David as Ron pulled the cub onto all fours while hugging him close, his breath hot in David’s ear

“I’m going to make love to you tonight,” Ron said, “I’m going to slowly fuck you and cum deep inside you.”

“Do it, Daddy” David moaned, “Make me your fuck toy!”

The mental picture of gently pleasuring his son, feeling his body surrender to the older tiger, and hearing his moans as the pair climaxed again and again was getting too much for Ron.  A gentle nip on his son’s ear was the signal that the hard fucking that David was enjoying was about to come to an end.

With a reluctant groan, Ron pulled out of David.  The cub gasped as the barbed penis tugged his insides in a very familiar way.  Now free of his son’s ass, Ron quickly stroked his penis as he focused on David’s shapely rear.

Ron was close to his second orgasm of the session and it only took a few strokes before he felt the familiar pressure begin to rise.  Aiming carefully while still stroking his cock, he unleashed the first jet of cum across his son’s back

The first line of cum was joined by two others, leaving three white trails along David’s back.  A giggle brought Ron back from his orgasm induced high.

“What’s so funny, David?” Ron asked

“I’m all sticky, now.”

Ron considered the situation.  His son was on his belly in front of him with his cum soaking into his fur, he was still horny and it would be hours until his wife got home.

“Looks like we better hit the shower,” said Ron as he squeezed his son’s ass before leaning in close to whisper in the cub’s ear, “I need to clean my fuck toy!”
