Teaching an Old Dog New Tricks Story By Ajax B. Coriander Commissioned by Westhoff

Monty took a deep breath, trying to settle his nerves. He knew he shouldn't be worried; it wasn't the first time he'd had sex. He was nearly sixty, and when his wife was alive, god rest her soul, they'd had a healthy sexual relationship. No, the fact he was going to have sex wasn't making him nervous, it had more to do with who he was about to sleep with and why he was going to sleep with him.

The Saint Bernard was here tonight to learn a profession that had existed for nearly as long as sentient species had walked the earth. He'd already collected everything he'd been told to: the hotel's nightstand already had a box of condoms, lube, and a few toys that he might need. He'd dressed for the occasion as well. He'd been told to play up the fact that he was an older fellow by wearing a pair of slacks, a sweater vest, and a pair of rounded glasses. His teacher told him that a lot of guys like those "daddy types," strong older men who seemed to know just what they were doing. Or they liked the thought of taking someone like their own father and bending them over to work out some issues. Regardless, he'd need to play the part.

He heard footfalls from outside the door and he felt his heart beat faster. He watched as the unlocked door slowly swung open and standing there in the doorway, backlit by that classic yellow glow of hotel parking lot lights, was a younger version of himself. The younger dog was around the same size as him, but he was a little smaller around the midsection. The extra years Monty had on him had caused gravity and time to give him a better belly that filled out his sweater vest well.

If anyone had seen them together they'd swear the two saints were related, and they'd be right. It was one of the things making the old dog a touch nervous; the dog standing there in olive cargo shorts and a black t-shirt was his grandson. Monty watched as the younger dog walked in, and gently closed the door behind him. The big dog clicked his tongue in disapproval.

"Already made a big mistake gramps, that's not how you greet a customer." The kid, who was twenty-five, took a few steps closer to the older dog, reached out, grabbed the older man's sweater vest, and pulled him into a kiss.

The older dog went with it, his head cocking to the side as his grey-flecked chin rubbed against his grandson's, their tongues dancing as the older dog parted his lips and let his flesh and blood inside. His hands slid along the thick canine's waist and came to rest on his hips. He closed his eyes a bit, and he found himself thinking of how the boy's grandmother would kiss him in just the same way. The younger dog broke the kiss and leaned in so he could press his nose to his grandfather's.

"That's how you say hello to a John, gramps," he said

The old dog grinned and looked deep into his grandson's eyes. "I guess you would know, Dell."

The younger Saint Bernard rolled his eyes and chuckled softly. "And don't call me by my name unless I ask you to. Just call me 'Sir'."

He reached down and grabbed the old dog's ass and gave it a squeeze as a playful growl rumbled in his chest. "That is who I am tonight. I'm your John. I'm here to teach you everything I've learned so when you take your first real client things go smoothly."

Monty nodded. "Yes, Sir." The words felt funny coming from his muzzle. He'd never imagined he'd be calling his own grandson 'Sir,' but of course he'd never imagined fucking the boy either. Or as tonight would lead up to, getting fucked by the boy.

"Okay, we'll skip over some of the boring stuff like how to get paid and how to select proper clients, and skip to when you actually land the John," Dell said as his paws slid around the thick Bernard's outer thighs.

"You need to make him feel comfortable," Dell said, before licking his lips. "You need to ask him what he likes."

Monty nodded. "Okay, well what do you like, kid?" he asked.

Dell gave a little annoyed grunt. "You need to ask better than that. Try 'So how can I make your fantasies come true tonight, Sir.' It sounds cheesy, I know, but it works. Oh, and don't forget to keep calling me 'Sir,' slip up again and I might need to skip a few lessons and get to some of the kinkier things." The younger dog's pearly white teeth showed as he smirked.

Monty cleared his throat and tried again. "So, Sir, how can this old dog make your fantasies come true tonight?" he asked.

"Well...it's always been a dream of mine to just toy with an older fella like yourself, even since I caught my gramps jerkin' it in his bathroom when I was a pup," Dell said, starting to get into character a bit.

Monty felt his ears flush red as he heard that; he could still remember that incident as clear as day. He wondered if that was the reason his grandson came to like the idea of having something under his tail, but that was most likely genetic.

"We can do that, Sir. How would you like me?" Monty asked.

Dell grinned, and slyly replied. "Naked."

Monty held back a chuckle. That much was obvious, and he was here to make the client happy, after all. He went to take his sweater vest off, but a set of paws stopped him.

"Let me," Dell said.

The dog found his grandson grabbing his sweater vest and pulling it off, the dog lifting his arms above his head, before it landed on a clump on the floor. Dell slid his paws over the fabric of Monty's silk undershirt, his fingers finding the buttons that kept the dog's body hidden away. He started to slowly undo those buttons, his green eyes locking with his grandfather's.

"See what I'm doing here?" Dell asked.

The old dog's head cocked to the side. "Taking my shirt off?"

The pup fought back another eye roll at that comment. "No. I'm making eye contact. Looking someone in the eyes like this starts to ignite those love centers in their brains. I've heard you can make someone fall head over heels for you if you can keep your eyes locked with them for seven minutes, but I've never tried it for myself," Dell said as he worked the fourth button off the old saint's shirt. "You want your John's to feel something. This isn't always purely about sex, it's about just finding a connection. That's why you messaged me on craigslist, right? You wanted to feel a real person. You wanted to have someone's warmth beside you. You wanted to hear their voice. Make them laugh. Make a connection... and then fuck them in their ass."

"True. It's been ten years since your grandma passed. I just wanted to feel something again." The old dog paused. "Though, I never imagined you'd be the one who ended up in my bedroom that night. If I'd known it was you, I don't think I'd have ever messaged you."

The younger dog popped off a fifth button, and then grabbed the old dog's shirt and ripped it apart, the last buttons popping off as that white chest with a nice patch of grey between the old man's saggy pecs came into view.

"Well, I'm glad you did message me," the young Bernard said as he grabbed that fat old St. Bernard's belly in his paws and shoved his muzzle right into that grey patch of fuzz on Monty's chest and taking in a deep long whiff. "I love your scent, gramps. I still can't believe I'm getting it right from the source, and not having to sneak whiffs of your clothes when I went to your house."

The old dog grinned. "Well you'll get it right from the source soon enough."

"In due time, I still have some things to show you first," the young dog mumbled into that old man's soft hairy chest. He took in another whiff; he smelled like what a real man should. He always had the faintest whiffs of pipe tobacco clinging to his fur, that sweet scent mixing in with his natural musk to create a combo that fueled many a pawing sessions in his younger years.

"But for now, I have some more things to see," the younger dog said as his skilled fingers reached for the old chubby man's belt, and in a flash the buckle was undone and those slacks fell to the floor, the younger dog gently guiding his gramps back onto the bed with a somewhat forceful paw. The old man huffed as he sat on the edge of the bed, and then had his pants ripped off. Dell licked his lips as he finally got to see what was under those pants. The old man's belly muffin topped over the bright red waistband of the new thong the dog had bought. The pouch clung to the package that had helped spawn the very boy that was now looking at it, as that thin strap was eaten by the man's large thighs, and eventually disappeared in territory the younger fellow in the room planned to explore tonight.

He reached forward, his fingers tracing over the kiwi-sized outlines in the old man's thong. "Very nice, but I would go for a jock next time. If the customer is really in a hurry it makes things go a lot smoother. They can just bend you right over that way." He leaned forward and started to gently nuzzle at that bulge, getting a nice long moan to escape his gramp's lips, before he reached forward and started to peal that underwear off, taking his time. He wanted to enjoy the view as he watched the man's sheath slowly peek into view, his cock already lipsticking from its fuzzy holder, as those fat Bernie balls finally spilled out. Those orbs rested softly against the old man's taint, before Dell finally worked the thong all the way off. He looked at the site before him. That old man was on his elbows, his ears up and excited like he wanted to take in every word that his grandson had to say. He leaned forward, his paw cupping his grandfather's balls, and rolling them around gently.

"People always underestimate the power of a paw job. It is one of those skills people have forgotten over the years as we've become orally fixated. But it has a lot of advantages," Dell said.

"For someone in my line of work, for example, it gives me a chance to check my client out and make sure there's no nasty surprises," the younger dog said as he reached forward and ran his finger across the tip of the old dog's shaft, getting a small pleasured groan from the older dog's chest. "You need to carefully peel down their sheath and check all the nooks and crannies for anything out of the ordinary," the pup said as he slid his finger along that fuzzy cover, before carefully sliding down that red pole inside. The same pole that started to react to those touches, slowly rising as the pup worked the fuzzy cover past the spot where his grampa's knot would eventually form.

He looked right into his gramp's eyes as he sucked on his finger for a moment, before sliding it down along that hot throbbing shaft, down to the spot where his sheath pooled around the base like the way someone's pants pooled around their ankles when they were about to get their dick sucked. He slid his finger between where red flesh met skin and he slowly pulled it out, his eyes shifting to check inside that opening as he ever so slowly let his finger circle all the way around that hot red pole. His finger giving a few teasing tugs just to make sure that his grampa's shaft never got bored as he did his inspection.

"If you copy what I just did most Johns won't even notice that it isn't part of the foreplay," Dell said.

The pup grinned. "Which brings me back to my earlier point. The lost art of the pawjob," the younger St. Bernard said as he gently wrapped his fingers around his grandfather's shaft and began to slowly stroke over that red length, "There's something as simple as the 'piano player' where you take your fingers and just gently tap against the underside of their shaft like you're playing the piano." The pup grinned, doing just as he said, his fingers gently tapping along the underside of that old man's shaft, making that shaft start to surge with blood as that pup teased the nerve endings deep inside.

"And then there's the 'soft glide'," the pup said as he wrapped his paw firmly around the red rocket that rested above those fawn-colored orbs. He began to just ever so slowly stroke his paw up and down that man's shaft until a soft easy growl was rumbling in his throat.

"And then that easily leads into the 'love tunnel'." Dell slid his free paw down and grabbed a bottle of lube from his pocket. He popped the top and drizzled it over Monty's shaft before using his fingers to slowly spread it out across the entire length, getting it nice and slick. He wrapped one paw around that pole, and started to slide it down, and the second he was able he wrapped his other paw around it and slid it down. He'd slide his paw down that length, and once he hit that chubby pad of fat, he'd let go, and grab the tip just as the other was about to bottom out. He repeated this motion over and over again, the old dog's leg's shaking, quivering, as he started to pant.

"And then there's my personal favorite, 'the bottle cap'." Dell grinned toothily as he slid his paw up that phallus and let his palm rest on the head of that star-tipped shaft. He started to slowly twist it back and forth like he was unscrewing a bottle cap or juicing a lemon. He heard his gramps inhale sharply through his teeth, the old man's face scrunching up, and his fingers gripping into the sheets.

"Oh fuck! It feels just like your grandma's muff when I fucked her at prom," the old man nearly howled.

Dell wasn't sure what to think of that, so he just decided to take it as a compliment. He kept at his work, keeping a close eye on his grandfather's knot as it began to slowly expand.

"Though, you'll also have to keep a close eye on the anatomical differences between customers. Like horses, you'll never hear one whiny louder than when you gently glide a finger under the flared head of their dick. And then there's dogs...you can pretty much get them to do anything if you know how to play their knots just right," he said as his fingers wrapped around that softly swollen knot, gently twisting back and forth before giving it a few teasing squeezes. He glanced up at his grandfather who looked like he was about to melt from the pleasure he was getting. But he didn't want to have him pop just yet.

"And another good thing to learn is how to keep your Johns nice and teased. You want to get them riled up, it makes them enjoy it, and more likely to come back." He licked his lips, "I'd show you how to give a proper blow job next, but I think you need to calm down some. So we'll move onto condoms," the younger dog said, before standing up.

He reached down and ripped off his shirt, his pants falling to the floor, showing he'd decided to forgo underwear all together. His cock was a tad bigger than his granddad's, but other than that it looked exactly the same, right down to the fawn-colored balls. Dell saw his panting grandfather smile a bit.

"You are one sexy dog. Back in my army days I would have loved to get my paws on you after a few drinks. Of course, I had to be real careful about it back then. It's why I still don't know much now," Morty said.

"Well I'm here to fix that," the pup said as he walked over to the nightstand, his erection bobbing under his white belly as he walked, the tip oozing pre as he grabbed two condoms from the top.

"I sure wish I would have had those when I was your age, but they were a lot harder to get in my time," the man said as he turned to look at his grandson.

"Alright, turn and face me gramps," Dell said as he ripped open one of the condoms. "I'm going to show you how to do this, and then you'll do it to me, alright?"

"Yes, Sir," the dog said as he turned towards his grandson, letting his legs hang off the side of the bed as that naked boy got down on his knees. "You want to just take a drop of lube and drip it in the top, this lets the area over the head move as someone fucks and gives a lot more stimulation," he said before he took the dog's knotted cock in his paw and gave it a stroke. "And never believe someone if they say 'I'm too big for them'. I've slid these things over dicks four times the size of most dildos. So they're lying, and most likely have something from the skanks that fell for that lie. It also doesn't feel different, at least to me anyway." The pup gave gramp's dick one hard stroke to make sure it was nice and firm. "Okay, now once you make sure the sheath is pulled all the way back, you want to gently grip the tip at the top and then just roll it down and over. But this part doesn't have to be boring, you can have fun with it, like this."

Dell placed the condom on the old man's cock head and rolled it just over the tip. He slid his lips over his teeth and he leaned forward to take that pointed cock head into his muzzle, slowly sliding his muzzle down along that length, rolling the condom along with it. Monty groaned softly as he felt his grandson's warm wet muzzle slowly slide down his length, his paw coming to gently rest on the back of that boy's head as he sank down until his nose was buried right into that old man's grey-flecked crotch fluff. He grinned a bit as he started to slowly bob up and down, his lips squeezing that shaft as cherry flavor rolled across his tongue.

"Oh, I love the way your muzzle feels," the old man moaned as he gave a soft thrust into that bobbing muzzle as his own grandson slowly sucked him off. He felt his dick pulsing in that young mouth as he rubbed between those floppy dark brown ears. The pup slowly slid his muzzle up until just the tip was in his mouth, and then he gave it one last quick squeeze before pulling off.

"Alright, now taking them off is just as important as putting them on. You want to point their cock downward, squeeze just behind the ring, and then just slowly slide it off." He did as he said, and slowly pulled the condom off. "Then tie it off, and toss it in the trash. Don't flush it. They can clog the toilet sometimes and that is a major mood killer." He stood up, a sly grin on his muzzle. He took the second condom and he tossed it to Monty, who caught it. "Now, I want you to do the same thing to me..."

The old dog nodded, and he took the condom and ripped it open. He followed his grandson's instructions, right up to when he rolled it over the tip. He just looked at it for a second, his paw idly stroking his grandson's dick and he felt his heart thump in his chest as he realized this would be the first time he'd ever had Dell's dick in his muzzle. They'd done so much, but the younger dog had yet to be inside of his mouth or under his tail. So, as he leaned forward, he closed his eyes and tried to just enjoy it as it happened. He puckered his lips, and slid them over his teeth. He took in the sensation of that hot flesh against his lips as he slowly rolled that latex down, his mouth opening a bit wider as he slid over the boy's knot bulge, until his nose was nuzzling that soft fluff above the boy's shaft. He inhaled that rich scent; it was so young and sweet, it was hard to believe that it'd been around as much as the boy claimed. He began to gently bob his head up and down, gagging a bit as his inexperienced muzzle tried to take that cock into his throat.

"Easy now, just relax. Don't try to do so much so soon. Try making a fist and squeezing down on your thumb, that will suppress your gag reflex a bit. It doesn't work on everyone but it can help." A gentle guiding paw rested between his grandfather's floppy, grey-tipped ears. He smiled as he watched the old dog do what he was told, and start to bob his muzzle a little deeper. The pup watched as that muzzle capped with rounded glasses just slowly moved along his flesh, his cock disappearing from that warm muzzle only to reemerge a few seconds later. It was a wonderful sight.

"Mmm just like that old man. Suck my dick like the good whore you are," Dell said.

He watched as the dick between his gramps legs flexed as he said that, and he grinned, enjoying dirty talk like that would come in handy in his new little hobby. He thrust forward, letting his balls tap against that grey flecked chin, that old dog moaning as he did. The dog pulled off, and he got ready to practice taking the condom off when his grandson stopped him.

"Not just yet... that condom still has some work to do before I take it off."

"Oh really, Sir?" The old dog asked with a playful growl in his throat.

"Yep, this bone is going to be buried in that hot fat ass of yours before the night is over, mutt." He said with a lick of his lips. "But first gramps, I'm going to need to get that ass ready before we start. I don't want to break you open before we even really get started."

The younger dog glanced at the nightstand, and his fingers wiggled over the selection of toys. Three dildos lay next to each other: a large horse, a medium canine, and then the smallest of the three at seven inches, the werewolf. It was a fusion of a wolf cock and another species to give it that perfect pointed tip with a knot that could easily slip it. It was perfect for a beginner, or someone who hadn't had something under their tail for a while, like gramps.

Dell picked up the toy and he smacked it into his other palm. "Now something you should always do before using a toy like this on a John is roll a condom over the top of it. All sorts of bugs can live on the surface even if you scrub them clean. I had a friend who accidentally spread something between a few clients because he didn't heed this rule." The younger dog picked up a condom and rolled it over that werewolf cock, the small knot bulging against the latex.

He grabbed his small bottle of lube. "Now. On your belly, gramps."

"Yes sir!" The old dog said, trying to sound confident, but there was a hint of hesitation in his voice. The old dog rolled onto his stomach and his grandson walked around the bed, his cock bouncing inside its latex wrapper, a small pool of pre starting to form at the tip.

Dell just stood back and took in the sight of his grandfather for a moment. That big fluffy dog had his legs spread, and he'd been kind enough to push his cock back so it pulsed against the bed, easily accessible to his teacher/grandson. He licked his lips as he looked at that ass, the tail already pulled to the side without even needing to be asked. He crawled up into the bed behind his gramps, laying the dildo down on the bed before taking out that little bottle of lube.

"Sex is sort of like a sport in a way, there can be winners or losers, but the main goal is to have a good time. And just like in any sport, you want to stretch before you really get into the game," Dell said with a lustful growl as he grabbed those two thick dog cheeks and spread them apart, getting a nice look at that pristine pink pucker in between. He was so tempted to just shove his nose in between them and lap his tongue across that puckered muscle, but he resisted. That would be another lesson.

"You got a nice hole gramps," Dell said.

"Mmm...I just hope it feels as yours did when I pounded you the other night, pup," he said as he gave a playful wiggle of his rear.

The dog let out a soft growl and he gave a quick swat across that old dog's ass, getting him to yelp. "I told you to call me Sir, mutt."

The dog pretended to whimper, and he said, "Sorry Sir. I forgot."

Dell nodded and used one hand to hold that old dog's cheek's spread with that pink pucker showing as he took the bottle of lube and drizzled that clear liquid over it. He watched as it clenched up as that cold lube touched it, and he felt a growl rumble in his chest as he thought about how good it'd feel to have that ass do that around his dick. He tossed the lube next to the dildo before taking one of his fingers and gently tracing it around the outside of that old man's hole.

"The easiest way to get a pucker like this to relax is to do some simple touching. It gets the bottom used to the sensation, and if you do it right, even the most inexperienced guys can take objects larger than they should," Dell said.

The old dog shivered, his hole spasming as he felt that finger softly smear cold liquid into his flesh. He heard his grandson growl softly again and he felt that finger start to push forward. He let out a surprised yelp as he finally felt his ring give way and that finger pop inside. He groaned as he felt his grandson start to work it in and out, twisting and curling it inside of him, making him thrust his hard drooling cock against the sheets.

The younger male waited until he felt that pucker start to relax around his finger before he slipped a second into that slick hole, making the old dog gasp. Monty whined uncomfortably as the younger St. Bernard began to tease his hole. That pup would wait until he felt the dog involuntarily clench, and then he'd spread his fingers apart just as it started to relax, forcing it to stay open as those muscles clamped down again, and then spreading it open a little wider, each time getting that old man's hole to stay open just a little more. Monty groaned through gritted teeth, squeezing the bed sheets.

"Oh fuck!" He groaned.

"You ain't felt nothing yet." Dell grabbed the dildo from the bed. As his fingers kept the old dog's hole spread, he brought the tip right to that puckered muscle and carefully slid in the tip as he slid out his fingers. The old dog whined as he felt that head slip passed his anal ring and those fingers slide out.

"Is it in yet?" He growled as he squirmed under his grandson.

"That's just the tip, you still got a long way to go," the younger Bernard teased. He heard an audible whine as that dog's hole squeezed down on the head of that werewolf cock with all his might. Dell squirted a little more lube on the dildo's surface and smeared it around. He leaned over his gramps, one paw starting to gently tease the underside of that old man's shaft as the other started to slowly push that silicone toy forward. The old dog whimpered and his cock flexed as he felt that silicone sink inch by inch into his fat ass. Dell just grinned as he heard that; it was like music to his ears. He slid his paw along that shaft to those white Bernie orbs, grabbed them, and gently squeezed. He watched as his gramps jerked, forcing another inch into his rear until it was pressing against that slim knot.

Dell began to gently grind that narrow knot against the old man's hole, teasing his pucker with that thick bulge, before he pulled it out just an inch or two and slammed it back in, making the old man yelp.

"That's a good boy, just relax that hole and take it all," the younger dog cooed.

Monty could only nod as he felt that toy start to slowly slide in and out of him, each inward thrust teasing his pucker with that knot, making him wonder if he'd really be able to take something like that. He also felt something else that made any discomfort worth it; it was the grinding of that toy against the pleasure spot deep inside of him. Every thrust of that toy would send a tingle up his spine that he hadn't felt since his days in the army. He shuddered, a deep needy whine in his throat as he pushed back into that toy, a deep moan escaping his throat as he felt that knot pop into him for the first time. That blissful bulge ground right into the gland inside of him that makes any boy or man beg when it got pressed.

"Oh god!" He shouted, his tail lashing out as his back arched and he pressed back into the silicone toy. He felt his grandson pull that toy out, before slamming it back in, forcing the knot inside of him. He did this again and again until the old dog was a whimpering puddle beneath him.

He leaned across the old man's back and whispered into the old man's ear. "Feels good, don't it?"

The old dog nodded quickly. "Yes Sir!"

"I knew a guy like you would love having something rammed up his ass. That caboose of yours was perfect for it. Not a lot of guys have a nice plump ass like this. It would have been a shame to not see a cock slide in and out of it... though, it's nothing compared to the real thing."

"Arf... no, it's not," the old dog panted as he felt that silicone cock slide into him again.

"You think you're ready for the real thing, mutt? You ready to have your grandson mount that fat ass of yours and pound you until that dog spunk of yours squirts across the sheets?"

"Yes!" The old dog whined.

"What was that? I didn't hear you."

"Yes Sir! I want to feel your cock in my ass until my spunk shoots across the sheets!" Monty howled.

Dell grinned, "That's just what I wanted to hear, gramps..."

In one fluid motion he yanked that toy from his grandfather's ass, brought his cock up to that stretched hole, and thrust right in, the old dog gasping as if the air had been forced from his very lungs.

"FUCK!" The old dog whined, trying to get used to the length of grandson cock now filling his ass. He arched his back, pressing that ass of his back against his grandson's, who groaned just as he sank into that wonderful plump ass. Both dogs growled lustfully, one from the way his grandfather's tight pink tunnel squeezed down on his shaft while the other growled from having that hot young lad's thick cock grinding into his prostate.

Dell began to slowly thrust in and out of that big plump butt as his belly ground into the small of his grandfather's back. He was able to adjust himself so his low-hanging white fluffy orbs would just ever so gently slide along his grandfather's exposed shaft, teasing it every time he'd thrust in or pull out.

Their hot bodies intertwined like so few grandsons and grandfathers ever do. Their bodies meeting in the most taboo of forms as that young St. Bernard thrust his cock in and out of his own flesh and blood, his young, potent balls slamming against the ones his own genetic code had come from. He growled at the thought, his knot started to swell, slowly started to slide in and out of that old man's ass, making his grandfather clench down around him in pleasure and pain.

Their floppy ears bounced with every single deep thrust of that thick canine shaft into Monty's ass. The old man started to hump against the sheets and he found his grandson's helping hand reach down and start to gently stroke that cock as its knot swelled. The old dog felt his face scrunch up, and he howled out in passion as he fulfilled his grandson's wish and came across those bed sheets, those old balls emptying as his grandson fucked every single last bit of cum from his grandfather's pleasure knot. The younger dog growled as he felt his knot swell and pop into his grandfather's rear for the last time. He threw his head back and howled as he came into his grandfather for the first time.

The two laid there panting, grandson still locked inside of grandfather as the boy's shaft pulsed, and his fuzzy white balls teased the sensitive knot on the old St. Bernard's cock. Dell leaned down and nuzzled into the old man's floppy brown ear and whispered.

"Good job grandpa, still think you need some practice on your technique. But with a little practice you're going to make one fine call boy... er, call grampa."

Morty turned back, panting, and smiled. "Thanks Sir."

Dell smiled, and he leaned down to give his grandfather a long, deep kiss as his cock flexed deep inside that old dog's fat rump.

The end.
