The back door of the little flower shop creaked as Asriel walked in. He took in the grey walls, the tiny kitchen, and the bare mattress laid out on the dirty floor. The seven flowers under glass seemed to shine in the dark room. The air smelled musty, with the damp that came from living so close to the lake.
"Geez, dad, you're really living like this?" The tall, slender goat walked inside and opened the fridge, admiring the single jar of pickles. "Damn..."
The mattress kept drawing his attention, laying there, sad and stained. There were streaks where sweat had seeped into it, and spots and dirty rings down below.
With his heart pounding in his chest, Asriel knelt down, put his face against the stained fabric and took a sniff.
Ahh...
There it was...
Between the stinks of musky sweat and acrid urine, enhanced by them, was that comforting scent he remembered so well...
He was so focused on the sensation that he didn't notice the back door opening again.
"Hello, little ones, I'm home." Asgore hummed happily. "I've brought you- Asriel?!"
Asriel looked up guiltily from sniffing his father's mattress, but he was too slow. The large goat rushed over with stomping feet and grabbed Asriel in his big, brawny arms.
"ASRIEL! I've missed you so much!" Asgore cried out, pulling Asriel into a big hug.
Fuck...
It was so much stronger like this...
Radiating out of his dirty Hawaiian shirt...
That scent...
Asriel's whole world became full of it. Every breath was suffused with it, filling him with comforting warmth.
And lust... so much lust...
His dick was straining hard against his pants when his father finally released him. He panted, trying to catch some air that didn't carry his father's addictive musk.
"G-Geez, dad..." He put a hand to his face, trying to hide his blush. "When did you last shower?"
"Hmm?" Asgore lifted an arm and sniffed under his pits. Asgore bit his lip, catching just a faint whiff of the stink buried under there. "Phew! You're right. I've been gardening all day, so I guess I would be a little ripe. I could have a quick wash..."
"No, no!" Asriel spoke a little too quickly. "I-I don't mind. And its been so long since we've seen each other."
"Yes, that's true." Asgore stood meekly with his hands by his sides.
How was such a big, pathetic lug so fucking cute? He couldn't bear it!
"A-Are you staying with your mother?" Asgore asked, desperate for conversation.
"Probably, though I haven't told her I arrived yet." Asriel gave a sly smile. "I wanted to see you, first."
"Aw, you didn't need to do that!" Asgore was smiling broadly, despite the words he said. There was a pause, where he looked a little nervously at Asriel. His son seemed to be breathing heavily, and his face was flushed. "S-So, was there something you wanted to talk to me about?"
Asriel took a deep breath, a sly smile sliding across his face. "Yes, there was." He stepped closer, putting one paw between Asgore's legs. "I wanted to pick up where we left off..."
"A-Asriel-!" Asgore squeaked, stiffening up. "I-I wanted to say... t-that was always a mistake... I wasn't myself... and you... you shouldn't-"
He was silenced by Asriel's tongue, forcing its way into his mouth. The older, chubbier goat trembled and melted as Asriel's dextrous tongue dominated his mouth. Asriel squeezed his crotch, massaging his growing bulge.
When the younger goat broke the kiss, Asgore was flushed and panting.
"Heaven, you are so pathetic..." Asriel licked his lips. "I've missed this so much..."
Asgore whimpered as Asriel went down, pulling the older goat's pants down with his teeth. Here it was, the source of so much of the scent, hidden behind those dirty cotton undies...
Asriel's eyes grew hazy as he pressed his face against Asgore's stained, tattered underwear, breathing in the unwashed, masculine scent that radiated from within. So strong... so potent...
"When was the last time you came? Your poor balls smell so pent up..." Asriel teased, hooking his thumbs in Asgore's waistband.
"P-Please... D-Don't..." Asgore whimpered, but Asriel was already pulling his pants down.
The mature goat's cock flopped out onto Asriel's muzzle, right in front of his eyes. Up close, he could smell everything. Sweat. Cum. Piss. Musk. Intoxicating heat radiating from those balls...
"Uh... Son?"
Asgore's worried voice brought Asriel out of his musk trance. He shook his head and focused back on the present.
"Your cock is already so hard~" Asriel teased, stroking a couple of fingers around the stiffening shaft. "You really needed this~"
He took the tip into his mouth and started sucking. The taste was rich and bitter, a mix of intense flavours each layering on top of each other. It was the most exquisite, delectable treat. Nobody else he'd tasted at university even came close.
Asgore was holding onto Asriel with trembling hands, not pulling him closer, but not quite pushing him away. "A-Azzy..." He panted, struggling with the words.
Asriel ran his tongue along the length of the shaft. "Hmm~?" He mumbled, making sure the vibrations of his voice travelled through to the root of his dick.
Asgore's whole, heavy body trembled. Another layer of sweat was dripping from his underarms, adding to the rich, olfactory tapestry that Azzy was savouring. His balls trembled and clenched. His hands moved up, gripped Azzy by the horns, then pulled him down.
The younger goat suddenly found his throat full of his father's cock.
"Azzy... Azzy-!" Asgore whimpered, tears running down his face. "I-I'm sorry...! I'm sorry-! Fuck, I need this...!"
After the initial surprise, Azzy effortlessly clenched his throat around the sizable meat in his throat. He relaxed himself, letting Asgore control the pace, using Azzy's horns like handlebars. There was passion and desperation in the way the older goat tugged on him, but Azzy never let himself be anything less than perfect elegance and control. He sucked on Asgore's cock like a pro, even as he was forced all the way down to the balls.
All that practice in university was worth it, just for this moment
He could sniff the rich odor of Asgore's crotch-fluff. The scent and dense fur there created a humid micro-climate all of its own. Fuck... he was so close to cumming and he hadn't touched himself once...
But there was something he wanted to taste first...
Azzy turned on the vacuum suction, willing all the cum in Asgore's balls to rise up. The older goat groaned as if his soul was leaving his body, while the younger goat's lips tightened around the base.
"Azzzzzzzzyyyyyyyyy-!" Asgore whined like a lost soul as he came, hard, down his son's throat.
Asriel swallowed the first, rich cumshot, then pulled himself back. The rest of his father's voluminous climax splashed onto his face and muzzle, filling his nose with the richest scent yet.
F-Fuck-!
Asriel trembled as he came, hands-free, into his pants. He jeans developed a significant stain in the crotch as he soaked up his father's scent. The musk... the sweat... fuck! He'd only scratched the surface.
Asgore was tottering, and fell backwards onto the mattress. His dick kept spurting, adding to the stains on the mattress. His eyes were glazed, and his dominant moment seemed to have passed.
Well, he wasn't going to let it end now. Not by a long shot.
Asriel tensed, and pounced on top of his father.

"Ooh... Oh... Oohngh..." Asgore moaned, his glazed eyes staring at nothing. He was laying on his front, his ass up, his cheeks spread as Asriel thrust his snout into the dark chasm between.
The younger goat was entranced, his tongue lapping and tasting all the bitter scents and dried sweat that had amassed here. He worshipped his father's pits, his balls, and his feet, but his asshole had a taste all to itself. Here, the scent hadn't just grown, it had 'aged' like a fine wine.
More... more! I won't stop... I can't stop...! I've got to taste the entire ass! Savour all this STINK!
Both goats grunted as they leaked cum onto the mattress below. They had long since lost count of their climaxes, only aware that their dicks were hard, hot, wet and slippery. There was no thought behind those eyes anymore, just pure, animal lust. The air in the room was heavy and humid, carrying a sweaty, sauna-like intensity that was enough to keep Asriel entranced.
There would be time for thought later. For one of them, elation and triumph, for the other, perhaps shame and regret, tinged with a sinful satisfaction.
For now, Asgore lay prone, awash in the sensations. Asriel lapped up the sweat that poured between his father's cheeks. The ambrosia that he'd been dreaming about, ever since that day, just before he left for university. That one night of alcohol, confusion, and lust.
The next time wouldn't take so long. Asgore would submit, again and again, letting Azzy taste that wonderful musk.
