"So like, did you see what Royal Guard oh-one and Royal Guard oh-two were doing? Omigosh, it was wicked grody! They were sharing a Nice Cream!"

Bratty started snickering, ending up in full-blown titters. "Oh my gawd! But they're like--, they're both guys! Guys don't do that!"

"I know!" Catty shook her head and groaned. "And then, I mean, like. They didn't even know I was there! I was just looking for stuff to sell, you know? And they started taking off their armor when the Nice Cream was gone."

The alligator blinked. A dumbfounded smile spread across her snout. "Like, really? Like, until they were naked?"

"Yes!" Catty yowled. "Oh my go-o-osh, it was so weird. Like, I mean, if it were a guy and Mettaton, I could get that..."

Bratty's eyes seemed to glaze over. "What if it were Mettaton and Mettaton?"

"Oh. My. God. That's the most amazing idea ever. That is wicked sexy."

"But--, ummm. What about the Royal Guards, though?" Bratty draped herself over the grubby mattress. Knees bent, feet in the air, she looked like a daydreamer. "Did they really get totally naked?"

"Yeah! And then Royal Guard oh-one - you know, the rabbit dude - he like, takes out his dick!" She dropped to her knees and leaned down, putting her face nearly in Bratty's. Her chubby body sloshed under her overalls. "And it's wicked huge!" she gushed, eyes wide and scandalized.

"Oh my gawd!" Bratty shrieked, pushing herself up to her knees. She and Catty laughed, caught in a chain of ohmygawd-no-way! for the better part of ten seconds before the alligator's expression leveled off.

The chubby cat tilted her head and smiled dumbly. "What's the matter?"

There was no embarrassment, only innocence in Bratty's voice when she asked: "What's a dick?"

Catty laughed and shoved her shoulder. "Oh, come on! Everybody's got a dick! They're awesome!"

It seemed to Bratty like just maybe Catty was right. The cat usually was, although most of the time their discussions had to do with how hot Mettaton was and how tasty Glamburgers were and how awesome it would be if humanity were eradicated. Now that she thought of it, Bratty realized Catty wasn't so much smart as just in harmony with her own opinions.

"Um. Sho-o-ow me?" the alligator asked, tail swaying back and forth. The leathery appendage batted against a box of unsorted junk she and Catty had yet to put up for sale. A small, dinged trophy reading NOSE-NUZZLE CHAMPS '89, 3rd PLACE fell out of the water-damaged box and clattered on the concrete, chipping away some of its tired, spotty finish.

Catty glanced at the clattering; Bratty didn't. She was well aware of what she had done. The cat wasn't distracted for long. Eyes wide and smiling to match, she started to pull down the shoulder straps of her overalls. "Sure, totally! That's the best part of a dick, showing it to other people!"

In all the years Bratty and Catty had been sharing the same alley and tending the same store (and obsessing over the same gorgeous rectangle), they had never been exposed to one another. It just wasn't polite or normal. Bratty saw her heavy friend's breasts first, and although she had been conscious of Bratty's plush figure, she had never been quite aware of it before now. Suddenly she was cognizant of her tiny, nearly flat boobs and slim hips. Being so mindful of her own mild figure made her appreciative of Catty's plus-sized one.

The cat's overalls hit the cement and there she was, naked and fat and very confident. Her black prick was stiff with childlike excitement, waggling under her belly like a stubby tail. Although uncircumcised, the glans was bared and wet. Fat balls in the same purple pile fur hung below it, pressed outward by the curves of her thighs, too chubby to leave any ball room.

"Like, ta-da!" she laughed. "Cool, huh? Let's see yours!"

Instinctively, Bratty recognized the shape before her. She played with one of her curls of hair. "I, uh, don't have one of those. Mine's an innie."

"An innie?" Catty asked, perplexed and adorable for it. She fingered her navel absently. "I mean, mine too? I don't get it!"

The alligator shrugged. Her hair bounced in lieu of other ladylike assets. "Lemme show you! It's super weird."

Before Catty's expectant, narrow eyes, Bratty stood on the crunching, protesting springs of the mattress. A roach scurried from under its pinched-up edge and hid behind the hotel's trash cans which the intrepid duo often pilfered for new merchandise.

Down went Bratty's slim and ratty jeans, exposing soft, long green legs with very little scale texture on them. She wasn't wearing panties (it was hard enough to find outerwear in the Underground, let alone clean underwear), and Catty's eyes fell predictably on the triangle of her thighs and loins. "Oh my ga-a-awd! What happened to your dick!? Did it, like, fall off or something?"

Bratty blushed and pushed her thighs together. "Well, I mean--! I never had one! This is so totally weird!"

"Oh my god, it is!"

Slowly and awkwardly, moving with shame now, Bratty pulled up her pants and sat down on the mattress. Another cockroach abandoned ship, crawling off into the shadows of the alley.

Feeling not at all shameful (why should she, when she still had her dick?), Catty knelt down with Bratty and pawed at the alligator's arms. It was one of her tics when she was excited. "Well anyway, like! It was so wicked weird when Royal Guard oh-one just bends over oh-two and starts licking him on the butthole!"

"That is weird! I don't even think our buttholes, like, do anything 'cause we don't eat human food." Bratty shuddered at the thought. "Then wha-a-at?"

Catty grinned. "It was even worse. He kinda climbed on top of him and he put his dick - and like, his dick is totally big, remember? Well, he stuffed it inside Royal Guard oh-two!"

"No way!"

"Yeah! And then I started thinking... I wonder how it feels."

Blinking, Bratty wondered where exactly Catty was taking things. The cat didn't actually seem to be taking it anywhere, but now her own curiosity was piqued. "You wanna... you know. Try that on me?"

The chubby cat's features lit up like a pinball machine. Her tail swayed madly from side to side. "Oh my god. That is just the best idea eve-e-er! So-o-o hyped! Yes!"

Bratty blushed again and leaned back, resting her weight on her stout tail. She pulled down her jeans a few inches; Catty urgently grabbed them and did the rest. "Okay, so like! Just lay on your belly, I guess! I'm gonna try licking your butt like they were doing."

When Bratty rolled over, Catty went for the tight curves of her bottom with obvious desire. She pried apart the cheeks, baring the pucker of her best friend's anus. It winked in reaction to the cool air outside its safe and warm little home, and Catty giggled at the sight of it. Then she lunged on it, going in without a second thought, slobbering and smooching with the same gusto she'd surreptitiously observed in the Royal Guards. When Bratty started to moan and squirm (just like he did! she thought, delighted), Catty tongued her even harder, slurping and unintentionally putting to use the roughness of her tongue.

"Ooh, gawd, ga-a-awd, that feels weird... nice, though." Bratty dug her nails into the edge of the mattress, making its faded and frayed seam split even more. Her tail, that heavy flail of leathery hide and armor scales, flopped back and forth over Catty's head, every collision with the cement a heavy thud.

The fat cat's drool ran down the narrow crevasse between Bratty's splayed cheeks, running over the split of her cuntlips where her hide was at its softest and almost the same texture as human flesh. It added to the moisture the alligator was already seeping, in effect leaving her sopping wet, but Catty was focused on her anus.

Suddenly (and regrettably for Bratty, who was engrossed in the rimjob), Catty pulled back and wiped her lips on the back of her arm, giggling like a ditz. "This is way more fun than I would have guessed! I bet this part's gonna be even better!"

Bratty didn't have to ask, even though she was going to, just because being an airhead demanded stupid questions - but the heavy cat mounting her and slapping that fat cock between her ass cheeks silenced her. Where her voice failed, her body language flourished; she pushed her soft, small bottom back, looking over her shoulder at Catty from her long neck. A bitten lower lip and blushing cheeks added up to a plaintive countenance, one Catty grinned at.

"You like it too, right? I can tell from your face, you look totally like Royal Guard oh-two did." She laughed and ground against Bratty, sliding her dark meat through the alligator's slim cheeks. Her laughter decayed into awkward chuckles, and then gentle croons. "Ooh, gawd... mmm, that feels super good."

"Feels weird," Bratty murmured. "This is what they did?"

"Well--! No, I mean," Catty mumbled, wide hips coming to an awkward halt, "this kinda happened by accident. They did this." The fat cat rocked back on her knees, grabbed her dribbling dick, and inclined again. She forced the broad head of her cock into Bratty's spit-shined pucker and pushed it forward with the blithe stupidity of the anally inexperienced, spearing her friend open with no grace whatsoever.

Tears welled up at the corners of Bratty's eyes. She grimaced, laying her chin on the mattress between white-knuckle fists. It was hard to put into words just how much it hurt, but Catty was cooing and moaning and muttering dumb little things Bratty was too distracted to pay much attention to. It occurred to the alligator that maybe this was something only monsters with dicks could enjoy.

Catty looked past her full breasts and belly with some difficulty, watching her penis vanish into Bratty's reddening anus. She rubbed the alligator's back - more things she'd watched the Royal Guards do - and crooned, "Gosh, that feels so good. No wonder the guards were doing this."

"It kinda hurts," Bratty muttered, miffed. "Ugh, did the King and Queen do this? Totally weird."

"I guess they did," Catty mused. Tail swishing, she pushed her stout hips in hard, bucking them against Bratty's flat, scaly bottom. The alligator shrieked and Catty flinched. A rodent leapt from behind the trash cans and scurried into a small fissure in the hotel's outer wall. "Jeez, don't do that! You could give me a heart attack or something."

"Well, it hurts!" the alligator snapped. "Be gentle, I guess, I don't know. Ugh, maybe the Royal Guards were doing this as training or something?" She grabbed a musty-smelling pillow from nearby and pulled it under her chin.

Catty, moving with a little more grace but still very clumsy, eased back her hips. As her friend sighed ostensibly in relief, Catty rubbed her shoulder blades. "You okay...?"

"I guess so. Just take it easy, it was rea-a-ally painful when you were going fast."

The cat nodded, keeping her slow pace. Slobber glistened on her penis and precum drooled into the tight alligator, lubing her virgin walls somewhat. A smile was tugging the corners of her mouth up. "God, this feels so good, though," she puffed, leaning firmly on her friend's bony shoulders. "I wish it felt better for you."

"Me too," murmured Bratty, wiping her eyes with the back of her arm. Her tears darkened the stripes on her arm warmer. What she didn't tell the cat, feeling more than a little ashamed of herself, was the fact that it was feeling better. A little period of adjustment led to a considerable amount of pleasure. The weird sensation of Catty's meat gouging her open and throbbing against her inner walls was a curiously pleasant one, and her cunt grew more wet against the mattress, adding to its innumerable stains.

A purr resonated in Catty's body. Sweat began to gleam in her fur, dripping off her brow and the bottoms of her thick breasts. "Ooh, gawd, I feel really strange," she tittered. "I'm all... I'm all tingly, it feels, like, so weird. Weird, but really good..."

"Lucky you," huffed the alligator.

Catty startled Bratty with a lick on the back of her neck. She purred more loudly for her. "Wh-when, god, when I watched the guards do this, something I've never seen before happened to them."

Bratty shifted on the filthy mattress. She tried to snake a hand underneath herself, inexplicably wanting to touch her heated muff, but Catty's weight was too much. She was not uncomfortable, but she was pinned. Absently she asked, "Mm, yeah?"

Save for her purring and the idly labored breathing that came with being fat, Catty was quiet. She licked her lips, gazing into the dark alley, thinking only about that strange and formless bliss welling in her body. It struck her as odd that it occurred all over and not just in her cock, which was where she expected it to be at its strongest. From her head to her curling toes, she was shivering with pleasure. That was the only word she could think of to describe the feeling. And whatever the pleasure was, it really made her want to fuck her friend's brains out.

"I'm gonna--, like, I need to go a little faster," said Catty, hoping that would absolve the fact that she was already starting to pick up the pace. Now her hips swatted Bratty's flat bottom, resulting in a muted pat of fur on leathery hide and a renewal of the hisses and winces from Bratty's rough lips. "Ooh, my g-a-awd... oh, god."

"Wh-what did they do? What happened?" Bratty asked with strain in her voice. She closed her eyes tightly to hide the fact that she had started to cry again. In spite of that pain, she was more wet than ever.

Catty mewled helplessly. "Well, they--, they like," she stammered, pawing at Bratty's back, playing with her long and pretty hair. "Oh, shit, it's gonna happen, I can't help it, it feels so good, I get it now...!"

Eyes rolled back, face pulled into a grimace of pleasure, Catty mewled again and smashed her broad hips into Bratty's ass, bottoming out. Her balls spanked the alligator's muff, grinding on her with their warmth and fullness. That moment of pain and pleasure for Bratty was interrupted suddenly when the cat let loose, shooting her spunk deep into her best friend's behind. It was the first orgasm of her entire life, and her balls drained themselves. One rope after another filled the alligator, whom squirmed and winced, her blush nearly as red as ketchup.

Every bit of sexual frustration Catty felt about the King and her favorite rectangle (and her best friend, if she wanted to be honest with herself) came to a head in that moment, changing her sexuality forever. The sum of years of not knowing what exactly her dick was for was being shot deep inside of the alligator whom finally stopped squirming, resigning herself to the fact that this was just how sex was unless you were a monster with a cock, yet the cat's overproductive load began to ooze out of her asshole, running down across the lips of her cunt and lightly gluing Catty's balls there with its stickiness.

The pleasure Bratty was feeling was nowhere near as powerful as Catty's overwhelming orgasm, but just as important. As the cat slumped over her, panting and whimpering and chattering disjointedly of how good she felt, Bratty found herself realizing where that cock was supposed to go.

Bratty decided to let her friend have her moment. She had the feeling that she and Catty would have plenty more chances to get it right.
