#14 of Kinktober 2021

Eh. I'm not too sure how happy I am with this one... I kept restarting it, and even now am not really sure how well I like things about it. Tipped pretty far into the musk/armpit territory, forgetting that 'armpit' is literally a prompt down the line, lol. But other than that, idk, just still kind of in a weird mood when it comes to writing, but don't want to just do nothing.

Decided to do some more with Cain and Abel, since I really enjoy writing them; elected to do something with Abel's... MAYBE canon boyfriend, Gan. Still trying to decide if I want them to be a couple for sure, or if it's just for fun in these Kinktober stories. Idk.


  1. Three (or more)some / Stripping / Sweat

(CW: Incest, Musk, Armpits)

Gan shuffled out of the locker room, a light blush on his cheeks. The chubby shark was almost completely naked, plump belly and heavy man-tits in plain view; the only thing he 'wore' was a slightly-too-small towel around his waist, which he kept both fin-like hands on to keep it from falling as he walked barefoot.

"Hey, babe!" the shark's boyfriend, a handsome and toned pit bull with sleek, black fur greeted. Abe was in a similar state of dress, though he didn't seem bashful of it in the slightest. Muscular chest and abs in view, towel tied around his waist loosely and allowed to sag over his defined hip.

"Was wondering how long you were gonna keep us waiting, kid," the older pit bull chimed. Once again, he only wore a towel, and while he was an Adonis of muscle, broad shouldered and thick armed, he seemed to share the shark's more self-conscious nature, keeping his arms crossed over his scarred-up chest.

Abe chuckled, nudging his dad in the side and objecting, "He's just a little slow to undress. You get used to it. But, now that we're all here, let's hit the sauna! I tell you, after the week we've had, I'm sure we could all use it!"

Cain rolled his eyes at his young adult son's declaration, but as the younger dog started towards the door down the hall labeled 'sauna', he began to follow. Gan took a few quick steps to catch up, and then was walking beside the titanic canine. The shark nervously looked up at his boyfriend's father's face, a slight blush on his cheeks; but he found himself grinning back when the older man offered a vaguely comforting, if a bit awkward, smile.

Gan was glad he'd seemed to hit it off with his partner's dad. The two pit bulls were close, VERY close, and he was happy to see that he was finding his place in their unorthodox relationship.

Abel held open the sauna door, letting a small burst of steam rise up from the top of the threshold to the ceiling of the hall. "Come on, you two! Sauna's empty, so we've got it all to ourselves!" the younger dog cheered, gesturing for his father and his boyfriend to go inside.

The shark and older pit bull obliged, stepping into the cozy, wood-lined room. Gan blushed warmly as Cain went to sit down, removing his towel first and setting his bare rump on the wooden bench, towel settled over his waist. That still did little to hide his immense bulge. Abel came in a moment later, giving his boyfriend a kiss on the cheek before adding some water to the heating element in the sauna, steam bursting up and filling the room.

"Have a seat, babe," the younger dog urged, moving to take his own seat. He did the same as the older dog did, briefly nudging off the towel before leaving it draped over his lap. Abe had sat down on the same bench as his father, but further down... with just enough space for the shark's chubby frame to sit between the two dogs.

Gan gulped nervously, nodded, and shuffled forward, awkwardly performing the same towel removal before sitting down. But, in setting the towel over his lap, he instead wound up dropping it to the floor, cursing softly as he blushed, lifting a leg as if to hide himself from, at least, the older dog.

"Hehe," Cain chuckled softly, setting his arms up on the upper bench, right about the level of Gan's shoulders; his arm touched the smooth, chubby male. "No need to be bashful, kid..."

The shark hesitantly nodded, setting his raised foot back down and leaning back, blushing and forcibly setting his hands up on his belly to keep himself from hiding his groin. Unlike the two canine's plump sheathes and heavy, furry nuts, the fish-man had a plump genital slit between his legs, no sign of external testes or penis in sight. He shuddered softly as he felt Abel nestle against one side, Cain just barely touching him on the other.

"... You ARE okay with this, right, Gan?" Abe asked softly, looking at his boyfriend with some concern. "I- I mean, I know it's... unusual, and we did talk for a while, but... If you're having second thoughts-"

"I- I'm not!" the shark declared, turning to face the younger canine. "I swear, I... I'm just not used to... being naked in place like this."

He let out a soft huff; the room was insanely warm, and he could feel sweat building up all over his chubby body. Cain, at his side, had begun to lightly pant under his breath, and slowly but surely, the smell of dog and shark sweat was filling the air in a pleasant, musky haze. So pleasant, in fact...

"Heh," Abe chuckled softly, leaning in to kiss his boyfriend on the cheek. "Guess the smell is getting to you, huh?"

"Wha?" The shark glanced between his chubby thighs, and blushed hotter, before squeezing them together with a yelp. As he'd been breathing in the mixed musk of himself, his partner, and the dog's father, his dick had begun to slip from its warm, wet slit, pressing out from between those plump lips to dribble precum from its tapered tip.

"Hah!" the older dog let out a laugh, throwing his head back. "It's fine, kid! Honestly, I wouldn't be surprised if Abe here was getting horny too!" Cain commented, reaching over the shark to nudge at his son's shoulder.

Gan was still blushing in embarrassment as the younger dog laughed as well, shrugging, "Okay, kind of! Mm, in fact..." He threw his towel off his lap, and then yanked the one off his father's body as well. Sure enough, a few inches of pink, throbbing dog dick had erected from Abe's sheathe, and a similar peaking red tip was swelling from Cain's. "Heh, guess we're all a bunch of musk-huffing pervs," the younger dog chuckled.

"See, kid?" Cain assured, patting the blushing shark on the shoulder. He smiled comfortingly when Gan looked up at him, adding, "You're in good company."

Gan smiled shakily at that. Sweat dripped down his body, adding a glistening sheen to his smooth figure; and he could feel himself growing particularly moist in a few areas. He supposed he couldn't be too embarrassed about getting hard around these two. Still a bit nervous, but growing steadily more comfortable by the moment, he let his chubby legs fall open, revealing that he'd grown fully hard by then.

"Huh. Don't think I've ever seen a shark dick before..." Cain commented, looking down between the pudgy male's legs. A bead of sweat dripped off his muzzle, joining the layer of wetness on Gan's body. The six inches of pink, tapered girth flexed at the older man's attention, Gan shuddering and blushing, but not hiding himself again. "... Not bad! Mind if I give it a touch?"

The shark gulped. "G- Go ahead..."

A moment later, the older dog's large hand was between his legs, fingers curling against the younger man's dick. He huffed softly at the touch, rough paw pads surprisingly gentle against his sensitive prick, stroking lightly a bit before just holding it against his palm, as if weighing it.

"Damn, kid..." the older dog huffed, licking his lips as he kept his eyes between the shark's legs.

"Feels nice, huh?" Abel commented, grinning. He, like his father and boyfriend, was building up quite the sweat, his short fur dripping and sagging with his own perspiration.

"Hell yeah... Never felt a cock this smooth before, pretty nice to the touch! Mm, and slimy..." Cain commented, removing his palm from the shark's cock for a moment, flexing his fingers and watching a few strings of clear fluid web between his digits. "It lubricates on its own?"

"Yep," the younger dog answered, reaching his own paw in to give the shark a few strokes. Gan whimpered, head tilting back against the back bench, his arms at his side as his genitals were teased and commented on by the father and son. "It tastes a little unusual, but you get used to it. And it's pretty good for giving the big guy a surprise jerk, hehe..."

Cain rolled his eyes. "You and your handsy playtime," he sighed, before bringing the fluid-dripping digits up to his muzzle, giving them a lick. Gan shuddered watching the older man lick up his secretions. "Mm... Not bad..."

"H- Holy fuck..." the shark whimpered, legs trembling as he sagged against the bench. He could no longer tell if he was only sweating due to the heat, or due to the arousing attentions of the two pit bulls.

The older dog ducked his fingers under his son's hand, still stroking the chubby male's cock, a few dull-clawed digits scraping at the underside of his sensitive slit. Gan whimpered again, almost moaning aloud as he was played with by the two canines. "Mm, slit is pretty nice, too... You ever fuck it?" he questioned, once again taking his eyes off the shark's genitals to look at his son.

"Heh, only about as much as I've fucked your sheathe," the younger dog answered with a shrug.

"A few times then!" Cain chuckled, smiling good-naturedly. Then, he questioned, "Mm... What about his armpits? You ever huff 'em?"

"A- Armpits?" the shark questioned, going a bit wide-eyed before glancing at his boyfriend. Now it was the younger dog's turn to blush in embarrassment.

"Hah! This pup could never get enough of sticking his nose in his old man's underarm," the larger dog teased, still wiggling his fingers inside the shark's slit. "He really never took a sniff under there?" he asked, looking up at the shark's sweat-dripping face.

"No..." Gan answered, blinking in surprise.

"Well... I mean, I didn't want to weird you out or anything..."

"... You literally asked me to join you in having sex with your dad," the shark pointed out, gesturing to the chuckling older canine. Before Abel could stammer out any further explanation though, Gan lifted his arm up, urging, "I mean, if you want to do it now? I'm pretty sweaty, though, so-"

"Oh fuck yes!" the younger dog cut off, grinning and tail wagging.

He didn't comment when his father began to laugh, opting instead to nestle under his boyfriend's arm and press his snout against the shark's smooth underarm. Abe gave a long, loving inhale, tail still wagging and flicking sweat this way and that as he drank in Gan's sweaty, musky scent. He huffed out contently, groaning in pleasure as his cock had visibly swollen to its full, aroused girth, ten inches of throbbing canine dick oozing precum and dripping sweat as the dog continued to happily and lovingly sniff at his boyfriend's armpit.

"G- God..." Gan whimpered. Abe's paws had settled on his belly and shoulder for purchase as the younger dog huffed his underarm sweat, but Cain had easily settled back in to jerking the shark off. "Y- You really like this, huh...?"

Abe whimpered, and then lolled his tongue out. He gave a long, tasting slurp from top to bottom of the shark's armpit, lapping up salty sweat and bitter musk before gulping it down, panting excitedly. "Oh, fuck... You smell amazing, baby..." he groaned, diving in for another long lick at his partner's underarm. "F- Fuck... Tastes incredible..."

"Oh?" Cain asked, raising an eyebrow at his armpit-huffing son. "Well, maybe I should get a taste if it's so 'incredible..." he suggested, flashing a smirk at the blushing shark.

Gan easily lifted his arm, exposing the opposite armpit to the older dog. "G- Go ahead, Cain..." he answered, blushing hotly. It was a bit awkward holding both his arms up like that, but it was more than worth it when the older canine ducked his head in and pressed his snout into the shark's armpit.

The shark groaned and shuddered, setting his arms down on the backs of the two musk-huffing canines. Neither seemed to mind at all, nestled underneath his chubby arms as their lips, tongues, and noses drank in all they could of the pudgy male's scent. Long, deep inhales, interspaced with short, repetitive sniffs, sometimes cut off by long, lustful slurps across his sweaty underarm, or passionate kisses. Gan whimpered, the two men's paws once again returning to his cock, teasing and stroking and fingering him as their mismatched partaking of his sweaty armpits went on.

Their muzzles, and faces in general, were soaked with the chubby male's sweat in moments. They soon leaned back, panting heavily, before Cain reached out and caught his son's floppy ear, dragging him into a kiss right over the shark's pudgy belly. Gan blushed, trembling as his cock throbbed in one of their paws, staring at the father-son makeout occurring right in front of him.

"Mm... Must be jealous of all the dad-smooches," Cain teased, glancing over at the shark and breaking the kiss briefly.

"N- No, I just-!"

He was cut off when the older dog leaned in and kissed him. Their lips locked together, and the father's tongue pressed into his mouth. Gan shuddered, gripping at the big canine's body as they now made out; he could taste his own sweat on the dog's long, flat tongue, bitter and salty and... oddly enjoyable.

Gan trembled as the kiss came to an end, a strand of sweat-laced drool connecting his lips to Cains' for a moment before Abe gave a needy whine. The shark turned and easily leaned in to kiss him now, groaning happily as the smaller dog's hand fully curled around the shark's prick, pumping away at it as they kissed. Despite the hazy pleasure, he was fully aware of Cain nudging his arm up again and leaning back in to return to huffing and licking at his armpit.

Abe whimpered happily as he kissed his partner, one paw curled at his cheek, and the other wrapped around the shark's slimy, tapered dick. The two dogs had seemingly agreed to leave their own dicks alone, four strong, canine paws stroking and groping at Gan's pudgy body, pressing at his belly, stroking at his dick, slipping fingers into his slit, and giving his plump, soft breasts a few squeezes.

"Ah- Oh, fuck," Gan whimpered, tilting his head back from the kiss, huffing hotly. He blinked some sweat out of his eyes, trembling as his cock throbbed in Abe's paw. "G- God, I'm so close..."

The two dogs seemed to take that as urging. Cain's fingers pressed deep into his sensitive slit, while the son's hand continued to twist and stroke all over the shark's dick, smearing precum, sweat, and other fluids all about.

All the while, they continued to lovingly huff and kiss his underarms, a sensation that Gan was pleased to find he was enjoying greatly, sagging back against the bench and trembling powerfully as a long, canine tongue slurped at his armpit, fingers pinching at his nipples as he moaned eagerly. The father and son had settled into wrapping their hands, fingers laced together, around his dick, pumping away at it as one.

"F- Fuck, fuck!" The shark whimpered, shook, and then yelped, back arching and head tilting forward sharply as he came. As his dick was being aimed straight up, the thick spurts of fish jizz that sprayed out spattered all over him, some ropes of cum falling to his thighs or the two armpit-kissing canines' paws, both most making a mess of Gan's snout, chest, and belly. He whined, overstimulated as the father and son continued beating him off, even as powerful strings of hot seed turned to a copious, oozing puddle of pearly white cum spilling out onto his stomach. It oozed across his sweat-dripping body, joining the mess on the wooden bench below.

"Mmf." Cain leaned out from under the shark's arm first, licking his lips happily and glancing down at the twitching shark prick in his paw. And, of course, at the mess covering the chubby, trembling male. "Damn, kid... Quite the mess you made," he teased, winking at the blushing shark.

"Ah... Um, th- thank you?" Gan answered uncertainly, even as Abe continued to kiss his armpit for a few moments. Soon, though, the younger dog also leaned up, panting hotly and eyes hazy as he settled up onto his rump.

"Holy fuck, that was awesome..." Abe panted, smiling at his boyfriend. "You're the fucking best, you know that?"

"Aw, n- No, I'm just-"

"Not every guy would let his boyfriend, and his boyfriend's dad, make out with his armpits and jerk him off in a public sauna," Cain pointed out, even as he settled down to sit beside the shark again, instead of being poised to stroke and nuzzle at him. Still, he gave the smooth, pudgy male's sweaty forehead a loving lick. "Trust me, kid, you're a good partner."

"Heh... W- Well, thank you, sir..."

Abe also settled against his boyfriend's side, much more clingy to the chubby male then his father, who simply hooked an arm over Gan's shoulder and sat with their sides and thighs pressing together. He hugged and kissed at the now-giggling shark.

"Mm," Abe hummed happily mid-cheek kiss, before smiling at his boyfriend. "You know... Dad and I haven't finished yet..." he pointed out, lowering a paw to nudge at his own throbbing dick. Gan glanced between Cain's thighs, where, sure enough, a similar but girthier canine prick pulsed and leaked against his sweaty leg.

"O- Oh..." the shark intoned, embarrassed. He was usually a bit better about making sure the guys he was with came before him.

"It's fine, sweetie," the younger dog assured, leaning in and kissing him on the lips. But then, he gave a low growl, and said, "Buuut... I'm thinking you should think up some way to make it up to us... Preferably with that big, plump ass of yours?"

"Mm... Sounds good to me," Cain assured, leaning in from the side and kissing at Gan's shoulder.

The shark trembled, nestled between the attractive canine father and son, both groping and kissing at him. He nodded, and shakily asked, "Wh- Who's first...?"
