Gracious Hosts

Chase brushed her hair while humming along to the song playing on her stereo, her bed littered with an open gym bag, stacks of her clothing, and some miscellaneous brushes, makeups, and deodorants. She smiled at herself in the mirror, wearing a white top tight enough to almost show her belly button, a short, black skirt showing off just a touch of her inner thighs around her legs. She giggled and turned around, playfully waving her butt at her reflection as the border collie gave her frizzled tail a few strokes from her brush, taming the wild mess that her morning shower had caused. Her ears perked up as she thought she heard something coming from downstairs, setting her brush aside and cranking the noise of her music down slightly, the voice of her father, Sebastian, finally audible over the ruckus, 
"Chase?! C'mon sweetheart, have you gone full deaf from that noise?" 
The teen opened the door of her bedroom, peeking her head out with a grin, yelling down the stairs, 
"It's not called noise, dad, it's music. Maybe if you listened to something other than what that 80s radio channel always plays you might learn that~" 
"Ouch, now that's just hurtful. I'll remind you that the tent we have is mine, and if you keep going like that then you'll be sleeping outside with the bears, little missus~! Also, get your backside down here, within the day would be nice. We're gonna need to leave pretty soon if we want to be there before the sun goes down."
Chase turned around, quickly shovelling her gear into the bag before zipping it up and throwing it over her shoulder, clicking her stereo off and skipping down the stairs. She spotted her dad standing near the front door, his olive cargo shorts topped with a fanny pack strapped to his waist, the girl immediately doubling over in laughter as the man smirked and adjusted his pouch, 
"What? It's functional!" 
"It also tells everyone that sees you that you're a history teacher. Good thing it's just us and the Burkes, otherwise I'd have to ditch you, wouldn't want to be seen around with someone wearing a fanny pack. I didn't even know they made those anymore."
Sebastian laughed and adjusted his fanny pack 
"Well firstly, Miss fashion, I don't think they do make them anymore, this is just from the back of my closet. And secondly, I wouldn't throw rocks from glass houses because your outfit isn't exactly prime material for a camping trip, unless you're looking to charm the mosquitoes into not eating you."
The pair laughed together as the dad grabbed the teen's bag, both making their way outside and into their car. 

After a few hours of driving, the city streets slowly changing into wilderness and fields, the two came to a stop at a small parking spot at the edge of a large forest, the car of a family living a few houses down their street already parked there, Sebastian stretching his legs as he grabbed the bags from the trunk, 
"Looks like the Burkes beat us, better hope we're not gonna be stuck with some awful spot for our tent, because I'm definitely gonna blame you and your singing for making us late."
"Yeah right, it's your driving that is to blame for that. And your navigation." 
"Alright, we'll call it 50/50 blame then." 
The canines hiked up through a small footpath, following signs leading them towards a campsite, eventually coming to a clearing after about fifteen minutes of walking, a tent already erected there. Sitting on a log bench near the tent were a pair of golden retrievers, the Burkes. Jeremy and his son, Tommy, stood up to welcome the newcomers, the fathers smiling and giving each other a fistbump as Sebastian heaved the backpack off of his shoulder, 
"I hope we didn't make you wait too long." 
"Nah, no worries. Just barely had enough time to put up the tent and sit down before you two came along." 
Chase and Tommy stared at one another, a sly smile on her face, the boy unable to stop his tail from wagging at the sight of her. He was almost three years younger than the 15 year old girl, but that didn't stop the pair from spending quite a bit of time together, their hangout sessions often devolving into exactly what one would expect when putting two teens going through puberty alone together in a room. Tommy walked up to the border collie, blushing gently as he scratched his neck, 
"Hey! That's… a really… really nice skirt…" 
She couldn't help but to smile at the cub's adorable attempts at flirting, his younger age showing as he stumbled over his words, trying not to make the fact that he was staring at her legs too obvious,
"Thanks, dweeb~"
She jokingly pushed him, lifting up his head with a finger under his chin, 
"Now stop gawking at my legs and help me and my dad put up our tent, please. I'll let you stare as much as you want later on~" 
Spurred on by the promises, Tommy eagerly helped the border collies set up their tent, Sebastian wiping his brow afterwards, sighing, 
"Alright, good job, we probably won't freeze in the night now. On that note, I'm gonna go fetch us some firewood."
As the man disappeared down a path, Jeremy stood up as well, 
"And I'm gonna go drain the snake, excuse me."
Both parents slowly sauntered away from the young couple, leaving them alone. 

Unbeknownst to the group of canines, the night before they had made their way to the forest, a small capsule had fallen from the skies above only a few hundred meters away from the campsite, alien life stirring inside. Triggered by movement near it, the capsule opened up, a small, slug-like creature crawling out from it, short tendrils waving around in the air, picking up things that human senses could never even get close to. The slug slithered through the brush of the forest, its soft and slimy skin slowly changing tone from an ashy grey to a dark green, helping it to blend into the environment, moving much faster than one would expect from the thing. To the creature, the place it had landed on was completely alien, nearly nothing in the forest comprehensible to it, but it was used to the feeling of being in a mystifying environment, following its exploratory instincts. The slug's senses were leading it towards something odd, something that stuck out from the surroundings, the alien climbing up on top of a large rock to survey the phenomenon it had discovered. Jeremy sighed in relief as he shook his dick a few times, the ground in front of him damp from the golden retriever having pissed out the soda he had chugged on his way to the campsite, his tail relaxed and his shoulders slumped down as he stuffed his cock back into his jeans, zipping up his fly and clicking his belt back into place as he muttered to himself, 
"Probably shouldn't have drunk that second coffee back at work, holy hell did I need that!" 
Quietly whistling, he turned around and was about to head back down to the campsite, when he thought he spotted something moving just barely from the corner of his vision, swinging his head around to see nothing except a big rock sitting there. Curious to see if maybe he had found some skittish bird or rabbit, he stepped closer, craning his head over the boulder to peek behind it, suddenly seeing something appear on the tree right next to the rock. He flicked his eyes to it, lifting an eyebrow as a large slug stared back at him, the mollusc sitting perfectly still before throwing itself onto his face, the dog stumbling and falling on his back from the scare and the impact. 

Before Jeremy even had a chance to do more except to let out a startled yelp and a grunt from the impact of falling on his ass, the alien had already slithered its way to the dog's ear, his eyes wide in horror and his maw open in shock as he felt the thing burrowing inside of his head, his scream for help halted before it even had a chance to begin. Within only a few seconds, the slug was inside of his head, moving around within his skull, probing and exploring its most recent victim, a weak nerve toxin released into his body to keep him fully paralysed but awake while it tried to figure him out. After a few moments, the alien had found the prime spot for its purposes, attaching itself right at the stem of the golden retriever's brain, tendrils wrapping around his spine and webbing all around his brain. Jeremy stared up at the darkening sky, breathing slowly, eventually blinking his eyes a few times before rising up into a sitting position, looking around with a very neutral look on his face. The alien was in complete control of him, it had the man's body as well as all of his memories, but it lacked the context for any of it, even the feeling of sight and smell being completely new experiences. He stood up, patting and poking at his body, examining the clothes he had on, running his fingers through his fur, sniffing the air around him. The slug was curious about everything and anything, from the birds flying high in the sky above him to the bugs crawling around on the forest ground, but he was most curious about his new host, the canine having many aspects and instincts that were completely new to the alien. He of course knew about it all through Jeremy's thoughts and memories, but none of it gave him the proper context for the feelings, it was as if trying to learn what love was through just the dictionary definition. What interested the slug the most was something that took up a quite significant part of the man's mind: coupling between two people, a way to have pleasure as well as to produce offspring. He thought of the idea of sex as very odd, something that required more studying. He needed a firsthand experience with the new concept, to hopefully give himself more context as well as to stimulate his host's body, new activities helping the slug to more quickly map out his victim's nervous systems. He began making his way back towards the camp, his walking starting off shaky and unsteady, getting more and more natural with each step he took. 

With both of their parents out of sight, the two lovebirds could finally relax slightly more, Chase pulling out a couple of granola bars from his dad's bag, handing one to the golden retriever as she sat down next to him, unwrapping her bar and munching down on it. Even while having a snack, Tommy couldn't keep his eyes off of his crush, his face constantly blushing whenever she'd glance in his direction and catch him staring at her, his excited tail whacking the bench the two were sitting on. Chase smirked and pointed at the boy's muzzle, 
"You got a crumb there. Let me get it for you~" 
She scooted closer to him, setting her hands gently down on his lap before leaning in and smooching him, moaning quietly. Tommy froze in place, his eyes darting around and his heart thudding in his chest, the older girl's touch thrilling him to the core even after the few months that the pair had been hooking up for. After a few seconds of trying to control his nervousness, he gingerly slipped his hands around the border collie, holding her as they kissed, Chase adding in some tongue into the action. She pulled her lips away from him, grinning as she watched his dazed expression, quickly licking the side of his muzzle before scratching under his chin, 
"There we go, got it~" 
She noticed the effect her teasing was having on the cub, his shorts starting to bulge out on the front, his excitement very obvious. She giggled and slowly stood, getting up only to sit back down on his lap, straddling his crotch with her thighs around his waist, her face only a hair away from his. She winked and pulled up the hem of her skirt, showing off how her panties were grinding right on his erection, a small patch of damp already visible on the front of the underwear. The golden retriever whimpered at the sight, completely melting down under her tender touch, the girl quickly pulling his muzzle up to go in for another passionate kiss. Her hands massaged his sides, sliding up underneath his shirt and feeling up his chest and belly, soon moving down to his nethers to grope and stroke at his throbbing red rocket through his shorts, the palms of her hands grinding on the bulge of his knot. 

The puppeted Jeremy slowly snuck up towards the campsite, a special surprise stashed in his belly, coming up through a thick brush and behind the campers' tents, his entrance completely hidden from the two cubs. He could hear the pair making out and giggling quietly, the alien taking a moment to just listen in as they made out, peeking an eye from behind a tree to watch the pair cuddling one another. Trying to come up with some sort of plan of action, the golden retriever finally stepped out into the open, clearing his throat and making both of the teenagers jump from the surprise, their heads swinging towards him, their faces twisted in embarrassment, 
"Dad!? I'm… I… uhh…" 
Chase quickly climbed off from the boy's lap, straightening her skirt and staring at the ground, unsure of what to even say to the man. Jeremy simply smiled and nonchalantly walked forwards, sitting down on the bench as if nothing special had been going on, speaking in a slightly odd tone, 
"Don't be alarmed. No need to worry."
The two lovers shared a quick look of confusion before focusing back on him, Tommy desperately trying to explain away the event, 
"It's not what it looks like dad! She was just… she was… she tripped and just… kinda fell forwards. And… and I guess she tried to hold on to my shoulders, but then… she… you know…" 
His words trailed off, the boy realising that no one was buying his story, leaving the trio in a moment of awkward silence. Chase broke the thick fog of deafening quiet as she coughed and turned around, 
"I… think my dad left our cooler in our car. I'm gonna… go get myself a soda."
The border collie quickly retreated out from the campsite, leaving the father and son duo sitting by themselves on the bench. 

Tommy stared straight ahead, sweating and fidgeting around as his fling disappeared down the small path, his tail curling around his waist and into his hands. He and his dad hadn't ever gotten to the subject of the talk, the border collie girl managing to wrap him around her pinkie before the two had the chance. Jeremy gently patted the boy on the shoulder, speaking in a calm tone, 
"You haven't done anything wrong, no need to feel bad."
"I… yeah, I guess. I just… you know… I know that you shouldn't do that sort of stuff… outside of the bedroom, I guess…" 
"How far have you gone with her?" 
The question made the pup's ears pop up, his muzzle cracked open as he turned his eyes to stare at his dad's nonchalant face. He hadn't expected his father to be quite so casual when approaching the subject of lewd stuff, the old dog usually not even liking to watch movies with suggestive scenes in them with him. Not wanting to question his parent's judgement however, the cub replied after a few moments of humming and hawing, 
"Well, we've… uhh… I guess we've gone… all the way? As in like… you know…" 
"You've… cum inside of her?" 
The question made Tommy instantly turn red, his dad's constant gaze not helping him at all, the young male simply nodding his head, too shy to even answer the awkward query. Jeremy knew that he wouldn't have all day long to be alone with the boy, his studies into his hosts going along too slowly, forcing him to take more direct action. With the cub's head turned away, he opened his maw wide and regurgitated a slug just like the one buried in his skull, the rest of the capsule's occupants residing in the dog's belly. Before Tommy could even react, the alien had already jumped against the side of his head and was burrowing down into his ear, the teen letting out one sharp howl before going limp, his father holding him up and stopping him from falling backwards as drool ran down the side of his mouth, his glassy eyes staring up into the sky. 

Jeremy watched the young male's eyes twitch, sliding closer while still holding onto the cub's shoulders, pressing his side to his son's as he reached down to his jeans. With a quick flick of his fingers, he unbuttoned and zipped down his fly, sliding his pants down to his thighs, his sheath exposed to the cool air. Tommy's head suddenly snapped straight, his pupils dilating for a moment before going back to normal, the pup blinking slowly before turning to face his dad, the two staring at each other before he shifted his attention down to the man's crotch. Jeremy let out a small gasp as the young teen's fingers grabbed onto his sheath, the sensation making his heart flutter and his jaw clench, a drop of precum spilling down from his exposed tip as more and more of his shaft revealed itself. The alien was starting to understand why his hosts thought these sorts of activities were so enjoyable, the exhilarating emotions and feelings coursing through the golden retriever's body almost making the man lightheaded as the cub leaned further down on his father's lap, grabbing onto Jeremy's knot with one hand while sliding the tip through his fingers, gently squeezing and playing around with it. Wanting to help the other body invader get properly acclimated to its host's body as well, the older dog reached down to grope the boy's crotch, Tommy squinting and groaning as he felt the hand pushing down the front of his shorts, curious fingers stroking and jerking his cock. He pulled his pants all the way down to his ankles, exposing his small ballsack as he leaned back slightly, probing around in the boy's memories to search for things to try out. He threw one of his legs up onto the bench, slipping his free hand down to his taint and poking around until he felt his finger tickling his tailhole, holding his breath for a moment as he slowly sunk the digit inside of himself, wriggling it around as his dick twitched and squirted out a shot of pre. Sitting side by side, the two canines jacked each other off as they huffed and moaned quietly, their intentions of simply exploring and studying all of the new phenomena that they had come across quickly changing into recreation, both finding the experience too pleasurable to stop. They wanted more, they wanted to experience all aspects of this new amazing discovery, and the two families camped out in the forest would be their path to make that come true. 

Jeremy groaned and bucked his hips up against his son's hand, sweating and panting as the muddy ground in front of him was slathered in his precum, the two dogs' hands crossing over one another as the pair moaned. The body snatchers were too caught up in their taboo experimentation to see or hear another person approaching their private moment, the golden retrievers focused entirely on each other. Chase was slowly walking back towards the campsite, a bottle of cold soda in her hands, the girl occasionally taking a sip of her drink in between her dawdling steps, hoping that by the time she got back to the tents her boyfriend and his dad would be through with their awkward conversation, wanting no part in it. As she closed in on the campsite, the trees lining the footpath starting to open up, she started hearing some odd sounds, her ears perking up to listen in. At first she thought it was sobbing, assuming that maybe the conversation that she was trying to avoid had gotten a bit deeper than expected, slowing her pace and carefully peeking into the clearing to see what was going on. The more she listened in on the situation however, the more confused she became, the odd sounds starting to resemble something very different from sobs. She finally managed to get eyes on the bench that the two golden retrievers were sitting on, her jaw dropping as she watched the father and son pair masturbating each other, Jeremy grunting and nuzzling the younger male. He let out a deep moan as his knees trembled, a strong shot of cum landing an impressive distance away from him, the second and third rope soiling his jeans as they splattered all over his legs. Chase couldn't believe what she was seeing, too focused on the show to notice how her grip on the glass bottle was slipping, the condensation forming on the cold bottle slowly causing her fingers to lose friction, her tail shooting up startled as the bottle dropped from her hand and shattered on a rock. Both of the males' heads immediately turning to her direction, Jeremy standing up and running towards her, the border collie frozen in terror for a brief moment before turning around to escape, only able to take two steps before being tackled onto the soft grass. Her muzzle was clamped shut by the much stronger canine, the man picking up the struggling and kicking girl as he dragged her back into the campsite, the trip all quickly disappearing into one of the tents. 

Chase tried to yell out to no avail, her fists pounding against the large male's chest as she was pulled into the tent, pinned on her back against the ground with both golden retrievers crowding around him, fear in her eyes as she watched Jeremy open up his muzzle, a creature sliding from his maw and landing on her chest. The slug crawled up to her ear, her arms held down against her sides to keep her from struggling as it slithered inside, her toes curling up. Having been stopped from blowing his load by the girl, only seconds away from orgasm before the interruption, Tommy was still hungry to satiate his newfound lust, his stiff cock poking at the border collie's exposed midriff, staining her fur with streaks of pre. Too impatient to even wait for the slug to fully take control of the girl, the cub nudged his father out of the way and crawled down between her legs, pulling her skirt out of the way and spreading her legs wide open, his breath ragged and feral as he looked down at her panties. He grabbed and ripped the pair aside, the scent of her feminine musk tickling his nose almost immediately in the enclosed space, his fingers stroking the fur on her thighs. The alien could remember being balls deep in the teenage dog's pussy, but he hadn't ever actually done it, left only with the hollow and empty memories, no feeling or context to them, only adding to his desire. Wanting to fulfill his need, he shoved his cock inside of her mound, immediately curling up and burying his muzzle in her chest as he moaned in bliss. Chase was still in a stupor, the slug in her head rooting around, an occasional twitch or an slurred mumble being the only signs of life from her as her young lover fucked her, the boy's father staring deep in her lifeless eyes, his girth starting to harden once more from the sights, the sounds, and the scents of the action happening in front of him. He still had some patience however, slowly stroking his cock as he waited for the border collie to regain consciousness, wanting the slug inside of her to get as much from the experience as he would. As he knelt next to her, his free hand gently pet her muzzle, two fingers gradually sliding into her maw, caressing her soft tongue as he huffed. 

Sebastian was returning from his trip, two plastic bags filled with firewood in his hands as he huffed and pushed himself up the small incline towards the campsite, finally setting his load down with a sigh and a grunt as he looked around, finding the place empty. He scanned the quiet clearing around the tents, raising an eyebrow at the sudden disappearance of the other family and his daughter, his nose picking up an odd scent lingering faintly around the campsite. He sniffed the air, closing his eyes as his nostrils flared, the questions in his head only growing louder as he realised what the smell was. The scent was only barely detectable, but it was undeniably the aroma of sex, the border collie knowing the odor very well. He began hearing quiet moans and thumping coming from the Burkes' tent, a grin forming on his muzzle, the man deducing that the two missing teens had been unable to keep their hands off of each other, having already had a niggling hunch that his kid and the young golden retriever were hanging out together for something more than just movies and candy. He stepped up to the gently shaking tent, not necessarily wanting to ruin the moment but still needing to get the teens decent before the boy's father was returning from wherever Jeremy had disappeared to, 
"Hey, lovebirds~! You two need to get yourselves decent and stop messing up the tent. If I can smell that from all the way out here, then Jeremy can definitely smell it when he gets back and climbs into there. If you really need someplace to fool around in, I can give you the keys to my car, just don't stain the back seat when yo-"
He was cut off as suddenly a pair of hands reached out from the tent, grabbing onto his legs and yanking sharply, tripping the man onto his back, his head bumping up on the ground, knocking him out momentarily. A fully naked Jeremy emerged from the tent, annoyed at the interruption, hunched over the border collie on all fours as he regurgitated a slug onto Sebastian's chest, watching it enter the man's ear before dragging his friend into the tent. 

The golden retriever set down the father next to his daughter, Jeremy noticing Chase starting to wake up from her stupor, her ears flicking and tiny whimpers coming from her with every thrust as the boy fucked her. Ravenous for her love, he quickly knelt next to her, pulling her head against his lap as he dragged his cock across her face, his tip poking at her lips. The alien in the girl took a few moments to get accustomed, quickly realising what he was after, parting her lips open just enough for his girth to slide inside as her legs stiffened, her boyfriend pumping away at her pussy. With one hand on the back of her head and another holding her muzzle, Jeremy gently guided the young border collie down his shaft, the cub using her memories of precious encounters to make sure she was doing as good of a job as she could, her soft tongue caressing the bottom of his dick as her lips glided across the length, applying the perfect amount of suction. Shivering from the blowjob his son's girlfriend was giving him, the man ripped apart the straps holding her top on, pulling the shirt down enough to expose her bra. He fondled and felt her tits up, pushing the bra off as she moaned against his crotch. Tommy groaned and exploded deep in her womb, painting her walls with his cum as he worked his knot inside, short and frantic strokes milking his cock as a heavy flow of his seed filled her up. Just as the boy had orgasmed, Sebastian opened his eyes and sat up, looking around for a moment before beginning to undo his pants, eager to get in on the action. Tommy had only barely pulled out from his daughter as he grabbed onto her sides and rolled her over onto her belly, sliding his dick between her legs as he laid down on top of her, poking around until his tip found her soaked opening. With the girl already in use, Jeremy sat down and motioned for his son to come over, tapping his lap as he grinned. The boy smiled as he crawled over to his dad, turning around and bending over, his tailhole guided down on the man's length as he slowly lowered himself, both males moaning as his ass was stretched open. 

With both of the incestuous couples hard at work, the tent rocked back and forth as the two fathers fucked their kids, Sebastian grunting and thrusting into his daughter's creampied slit while Jeremy pulled his son down onto his knot, both men balancing on the edge as they growled with newfound lust. Chase's maw was buried against a sleeping bag, her teeth biting into the soft fabric as she howled in pleasure, the stimulation overwhelming her completely, her breaths short and ragged. Tommy kept himself steady by holding onto his dad's knees with both hands, his half-chubbed cock bobbing up and down as he rode his parent's shaft, his eyes rolling back in bliss, his prostate battered and massaged by the older canine's girth. Orgasming at almost the same exact time, both fathers pumped their cubs full of their seed, the border collie's sperm flushing out the girl's womb while the golden retriever's cum spilled into the young boy's bowels, the pair both groaning and gasping in unison. Sebastian pulled his knot out from his daughter's cunt as he rolled over, panting with his dick pointing up and resting on his belly, dripping with juices and cum as he tried to catch his breath. Jeremy looked down at Chase's overflowing pussy, the fertile girl filling him with not just lust, but also giving him a perfect idea: the aliens would need hosts, much more than just the four they had currently, but capturing that many people might provide an issue. However, captured females could easily be impregnated to provide more hosts, the act of knocking them up even helping newly overtaken people to explore their new bodies and feelings. Jeremy gently pulled the cub off of his red rocket, moving between the girl's legs as he brushed his fingers over her clit, smirking as his cock rested between her pussy lips. Before anything else, he'd need to make absolutely certain that this female was pregnant, every load inside of her improving the chances of new hosts, the man being more than happy to provide his seed for the task.
