It was a quiet late night as the large wolf slept in his bed. Lights off, only a little moonlight coming in through the window hitting the old adult, barely lighting him up. The wolf let off a small huff and whine as he rolled over, eyes opening from his slumber, looking at the ceiling and letting out a sigh.

"Fuck..." he grunted as he swing his legs to the side of the bed and managed to prop himself up. The older man had woken up with a sudden need to use the bathroom. He let out a sigh as he stood up, and walked out the door and to the left towards the bathroom. He walked in, not even bothering to turn the light on since he could see in the dark well enough and slipped his boxers down a bit, wearing nothing else as it was quite warm. He then peeled his sheath back some to expose a bit of his limp cock as he stood at the toilet and soon sighed, a golden arc spraying forth as he took a much needed piss. In and out he thought. He'd be back to sleep in no time. He had no idea how wrong he was.

Soon enough the stream slowed to a halt, grabbing some toilet paper to wipe off his tip and a little dribble on the sheath, tugging his boxers back up and flushed the toilet and going to wash his hands. Once he was finished he walked back into the hallway to go back to bed. Just before he slipped back into his room he noticed a bit of light peaking out under a door in the hallway. He let out a bit of a grunt. That door was to his sons room. It was late and a school night and his son should have been asleep, but it seemed he wasn't. It was nearly 2 a.m. as is when he looked at the clock in his room before he'd gone to the bathroom. He pushed himself off the door frame, his paw having had moved to it as he had started to turn the corner initially and now headed off towards his boys room. Luckily the door had no lock, something he wasn't going to let his boy have till he was older. He opened the door and started to walk in, eyes clamping up briefly to adjust to the light.

"Dammit boy. It's nearly 2 a.m.! You should be asl..." was all the large male got out before his eyes re-adjusted to the lighting and he saw his son. There he was. That little twinkish fourteen year old boy of his bent over on his fours, a paw behind himself shoving a dildo into his ass with his tail raised, the boy wearing nothing but a collar that was hooked to a leash that was wrapped around one of the poles at the corner of his bed. The man stared for a moment as his boy looked back in abject terror.

D... Dad?! I... I thought you were asleep! I.... I can explain..." the boy said with a heavy blush. He had just been caught and even though he said he could explain, there was no lie he'd be able to come up to deal with this scenario. That's when the father smirked a bit at his son.

"No need to explain... Keep going boy. Don't let your old man stop you." he said as he watched, not exactly surprised at the scene he saw in front of his as he leaned against the door frame, taking up every inch of space that door had to offer. The older man was huge. He stood a good seven feet tall. He had a little bit of a beer gut, but he was pretty well toned overall. Even for a wolf he was pretty pretty large, an impressive specimen of his species. His son on the other hand not so much. He was only about four and a half feet tall, and was rather skinny. He was so small and lithe that he was easy to mistake as a girl from behind.

"D... Dad?" the boy said with a blush, looking to the mans face. Soon enough the dad let out a small growl and the boy blushed more.

"Did I stutter boy? Get on with it." the father said with a stern voice. Soon enough the boy blushed and looked forward as he started to push that small canine toy in and out of his hole again and let out a small moan. The father was always seen as strong and more dominant. With his size it wasn't exactly a surprise. He just radiated an energy that told anyone nearby that he was in charge. What was a surprise to the kid though was when he felt some added weight to his bed, and soon enough he found a bulging crotch in his face, the kid looking up with a blush.

"D... Dad...?!" the boy asked with a blush. One of those large paws came down and rubbed the back of the boys head as the small wolf stopped using his toy while he looked up to the man. The father looked down with a grin as he reached down with his free paw and hooked it into the front of his boxers and tugged it down, the boy letting out a small squeak as suddenly a heavy cock fell right over his snout. Not only was his dad tall, but he was big too. The young wolf blushed as nine and a half inches of thick, musky cock lay over his snout.

"You know boy. Your not as sneaky as you think you are. I've caught you sneaking a peak on me when I take showers. Bet you were trying to get a look at your old mans cock weren't you?" he said with a growl, flexing his dick across that maw. "Well here it is. Why don't you get acquainted with it." he growled out, grinding his dick along the snout and the boys nose, marking his fur with his scent. The younger wolf whimpered as he breathed in the strong scent of the adult, letting out a nearly girlish whimper as he gave the large pole a gentle lick, the dad letting out a small groan as he rubbed his kids head.

"That's cute son. But I bet you can do better." the man growled out as he tugged his cock back, moving a bit to get his boxers off fully now, getting in front of his boy and holding his tip in front of the boys muzzle, a paw reaching out to grab at that leash where it was tied to the bed frame, soon holding it in his paw as he smirked. He soon brought his other paw down, gripping the maw a bit and pushing his thumb at the tip and carefully pried his boys maw open, giving that leash a tug and pulling his boy down a bit, sliding his musky tip along the tongue and just inside the maw.

"There we go kiddo. Now why don't you just slide that cute little muzzle of yours down your old mans cock and show him what you know." the father growled, giving the leash a tug, earning a squeak from the boy. The young wolf blushed like mad, ears folding back, but he didn't fight it. Soon enough he started to slip that warm maw down his fathers dick, taking about a quarter of it. Not only was his dad long, but he was thick, and the young wolf pup had little experience. Slowly the boy started to slide up and down, working that large pole in and out of his tiny maw, taking what he can, earning some groans from his dad along with some musky pre. He kept this up for a bit until he felt the leash tighten and tug forward. The old wolf had snaked the leash under his legs and around himself and was tugging hard, forcing that maw to slide down his cock more as he started to thrust a bit.

"F... Fuck... That's it son... You look good with a cock in your mouth. Especially mine in there..." the old wolf growled as he tugged that leash more, earning a little whimper from his boy. The dad kept fucking his kids mouth for a bit, one minute, two minutes, three. It felt like an eternity to the kid, but also like it was no time at all as soon that huge length was tugged free and slapped over his snout with a wet smack, a splash of pre blasting between the eyes.

"D... Daddy... Y... You taste really good..." the pup whimpered a bit. The father smirked and ground his cock along that snout a bit more as he held that leash a bit longer before fishing it back through his legs, holding it normally again, but not giving the boy any slack to pull away from his cock, not that he was trying to.

"Good. Because that is NOT the last time your going to taste it." the dad growled, giving that leash a little tug as he ground his cock to the snout, getting his scent into that fur as the boy whined. Soon though the dad scooted away and before the boy knew what was going on, his dad was behind him, his free paw grabbing his and tugging that toy from his hole, and almost as soon as it was that nine and a half inch monster slapped right over the boys ass. Compared to the toy the boy had been using, his dad was still huge. The toy had been at best six inches and fairly thin, nothing like his dad.

"Go on son... Beg..." the dad growled out, giving that leash a tug.

"D... Dad?" the boy asked with a blushy whimper and a squeak when he was tugged by the leash.

"Did I stutter? Beg for daddy to fuck you! I know you want it you little slut..." the dad growled as he tugged the leash and ground to that hole more, making the kid whimper gently.

"P... Please daddy... F... Fuck me.... Please..." the boy whined out a bit quietly. The older wolf growled out as he gave that leash another firm tug.

"Louder! Make me believe it!" he said as he gave out a loud, dominant growl, the boy whimpering and pinning his ears back.

"P... Please! Fuck me daddy! Fuck your son! P... Please stop teasing me and just fuck me already!" the cub whined out loudly. The old man growled as he tugged back, nudging his tip to that ring and grinding.

"As you wish kiddo." he growled out and with a firm tug of that leash and a firm push forward, the old wolf moaned as he watched as his cock stretched his own sons hole hard, spreading it wider and wider, pushing in totally bare into his sons tight little ass. The two moaned as the moan tugged that leash and pushed those hips in and soon there was a dull thud as those hips pushed to that tiny little butt and those heavy balls smacked the back of his sons.

"F... Fuck... For a slut your tight..." the dad moaned as he ground inside a bit, making the young pup blush. Even though he'd been using the toy just before it did nothing to really get him ready for the length and firth of the father, that boys tummy bulging a bit with cock from the size of it.

"I... I'm not a slut dad... Y... Your my first..." the boy whimpered out, the dad's ears perking as he grinned. He figured since the boy had the collar and leash and a toy and was playing with his ass he had at least some experience with others, not to mention how he managed to never get any teeth on his dick while sucking him off.

"Oh yeah? Is that so? And you just let your old man stick his dick in you no questions asked. Just like that? You want daddy to be your first? You want him to fuck you raw? Just let your old man use you like a little toy?" the wolf growled out, making the boy whimper more as he nodded. The boys poor cock was throbbing so hard below.

"Y... Yes daddy... I want you daddy... I... I want you to have me... to be my first..." the young boy whined out. The dad growled more at that, grinding harder, holding that leash taught.

"Then that's what your going to get boy." the man moaned out as he tugged back, nearly all his dick sliding out before he thrust in hard, then doing it again and again, moaning as he tugged the leash hard, pulling his son back into him. The kid moaned out as his dad started to fuck him. He could have been gentler, but he wasn't. He watched how his cock slid in and out of the tight underaged hole. He watched how his knot beat that hole and spread it a bit more each time. He watched how every thrust he made forward pushed his little boys body forward some only to get tugged back by the leash. If he could have seen below he also would have seen that tummy getting distended with cock and that young cubhood flopping about.

"Rrrfffff... Such a tight little ass you got... Feels good doesn't it... Letting your old man claim your ass. You love it when daddy fucks you don't you?! How he stretches you. How he fills you." the wolf growled out and moaned as he thrust harder and harder. The young boy moaned loudly as his old man took him. Luckily not much sound could be heard from the room. The old man had given his son this room as is because it was further from the neighbors and a little more sound isolated so he could be as loud as he wanted without bothering anyone. Of course it was never intended to hide the sounds of the boy getting railed by his own father.

"Y... Yes daddy! I... I love it! It feels so good! P... Please! Don't stop! F... Fuck me dad!" the kit whined and begged as his dad plowed him. The only earned a louder growl from the old man as he fucked his boy hard, hips smacking to that ass, and large, heavy balls smacking to his sons smaller ones below.

"That's it boy! Enjoy daddies dick! Dad's gonna fuck you so much!" he moaned out as he thrust, a somewhat audibly wet smacking starting to fill the air from all the pre the man was putting in his boy, not to mention lube that the boy had been using as is with the toy. "From now on when daddies horny, he's gonna fuck you. And when my little boy needs a good dick daddy will fuck you. That's what you want isn't it? Want to be daddies little cum dump don't ya?" he moaned out. The kid whined and nodded as his dad continued to just thrust away.

"Y... Yes daddy! Make me yours! M... Make me your little fuck toy... Oh god... J... Just fuck me any time you want! M... Make me your toy!" the boy cried out, barely getting out the last of it as the old man tugged the leash hard, making the boy gag as he tugged him back into those thrusts more. The man going so hard at this point it was leaving that ass a little red under the fur. It was like he was being spanked, but so much better.

"Rrrrrr.... Good boy... Daddies little cum dump! Rrrrrr... You deserve a reward for being so good!" the man growled out, tugging that tail and leash harder. As much as he wanted to hold off his orgasm he was getting close. It had been a few years since the man last had any sex, and the kid was getting the brunt of that pent up need, and neither of them could be happier. The two moaned loudly as that knot spread the hole more and more.

"D... Daddy! Daddy!" the son cried out as his father claimed his sons virginity on his own. It wasn't even a minute later until the two moaned out hard as the large wolf tugged that tail and leash hard while pushing forward, a loud pop practically echoing in the room as every last inch of that cock was shoved balls deep into the kid. The dad groaned as his cock twitched, cumming hard inside, emptying load after thick, heavy load of cum into his only son. He growled out as he looked at that stretched hole wrapped around the base of his cock, kissing his sheath fuzz as he unloaded into the boy.

"Fuck yeah boy... You feel that? Daddies pumping you full of the same cum that made you... Feels good don't it? All full of daddies seed?" he growled out as he ground inside, knot and cock throbbing as he kept cumming, practically bloating that little tummy.

"Y... Yes daddy... I... It's so warm... I love it..." the kid whined out as he ground back a bit himself, earning a moan from his dad. The two panted as the older male took his boys hips in his paws and held him firmly against him, keeping himself locked inside that tight little body.

"Good. Because daddies going to fuck you every day. Whenever he wants to. And he WILL fuck you before bed every night. Your not wearing clothes anymore around the house. Only the collar. I want my little fuck toy easily accessible." He growled out, reached to lean over some and grip his sons chin, leaning down and curling himself a bit to talk right into the boys right ear. "From now on your mine. Daddies going to train you. Turn you into a real slut. You'll like that won't you? Wanna be a little slut don't ya?" he growled out into the ear. The young wolf whimpered and nodded once more and squirmed below the larger male.

"Y... Yes sir... I... I will be naked for daddy... I... I wanna learn. I wanna be a slut..." the kid whined out, like a kid begging his parent for a video game or some toy they really wanted. The large wolf grinned and sat up, holding those hips hard as he started to tug. The boy moaned as his fathers knot tugged at his hole hard from the inside until there was a wet squelch and a loud pop, that large bulb slipping out with the rest of the cock. The large wolf grinned as he rolled his boy on the back and lifted his legs up, scooting closer with an almost evil grin across his snout, tugging that leash a bit.

"Good. First lesson... Daddy can go more than once... Your in for a long night kiddo... And a long day. I'm calling you in sick from school and I am calling in sick from work. Were going to spend all day together." he said with a grin as he aimed his cock and started to shove right back into the boy, not stopping till his knot kissed the hole, and immediately tugging back and thrusting, albeit slower this time. "Daddies going to spend all day using you. Every way I can. And your going to love every second of it. Daddies good little cum dump..." the man growled out, making the boy blush. What had that young wolf gotten himself into he wondered. At least for a brief moment.

"Y... Yes daddy... Please daddy... Teach me..." the boy begged out. It was going to be a long night and day. The start of a new life for the two. Daddy was going to get all the sex he wanted, and his son was going to get all the sex he wanted, and neither of them could be happier.
