Red rubbed his fingers over Kiro’s crotch, enjoying the quiet gasp from the reptile under him as his fingers glided over the smooth scales. He admired the simple beauty of his boyfriends anatomy, the way the smooth scales flowed from his navel-less belly down to his tail with nothing but a crease where the long, thin, whiplike limb met his body and a barely-visible slit running crosswise right at that seam, the only opening into his body other than his mouth. He closed his eyes and dipped his snout to the thin break in Kiro’s scales, flicking his tongue out over the slit, tasting nothing but a slight saltiness. Evidently his love had cleaned up out of habit, forgetting that his mate preferred it when he smelled like himself, and even more when he didn’t wipe very well. That wouldn’t matter shortly however. Red smiled, unable to keep from fantasizing about the near future as he lapped at the reptilian slit, pushing the tip of his muzzle against it as he bathed his boyfriends vent in saliva.

Kiro moaned above him, “Jesus, Red… god, you know what you’re doing down there.” Red responded by shushing him gently, then took a deep breath and pressed his snout hard against Kiro’s vent, pushing his long, thin tongue between the edges of the cloacal opening and into his boyfriend's body. Kiro gasped again, much more loudly, as the rough, slick muscle forced its way into the incredibly sensitive flesh of his vent, flesh never meant to feel the touch of another being, and involuntarily thrust up against Red's muzzle, pushing his crotch slightly off the edge of the bed he was sitting on. Both creatures were cold-blooded and Red’s tongue had just been waving around in the open air, so the slight temperature difference felt tangibly cold, making him shiver and sigh as his boyfriend made out with his slit. The strange sensations were nonetheless arousing, and his dormant cock began to stiffen inside his vent, quickly sliding out into the open air and eliciting a pleased hum from Red as his tongue was pushed out by the slim organ.

The membranes in Kiro’s slit kept his cock slightly lubricated with a greasy, somewhat salty substance for which his lover, free of principles as he was, had of course developed a taste, making it hard for it to ever serve its purpose, although neither of them minded, being the sort of couple that bought lube in quarts. Even before Kiro’s slim lizardcock was fully erect Red had opened his muzzle and engulfed the entire shaft, eagerly licking the greasy secretions from it. As he washed his tongue all over the stiff flesh Kiro moaned and bucked up into his muzzle, thin precum already dribbling liberally from his cocktip. Red’s hunger for his mates body was incessant, and he quickly licked up and swallowed every drop of fluid, enjoying the sweet pre complementing the salty natural lube.

While Red voraciously licked at his cock Kiro lay back and closed his eyes, trying to ignore the pleasure momentarily, and bore down. He wanted to surprise his boyfriend with one of his favorite fetishes, but it would be difficult since his anatomy was inconvenient for it, and he didn’t know if his bladder was full. His bowels certainly were - so much so that his belly was a little rounder than usual, which he hoped Red hadn't noticed as he preferred to surprise him. Much to his chagrin (hardly, in truth) his bladder was not empty, and he cursed it quietly in his head but concentrated on relaxing himself nonetheless. Red paused and chirped in surprise as urine started to dribble out of his boyfriend's vent, but despite the surprise he didn’t miss a beat, angling his muzzle up so he would catch Kiro’s piss in his maw. The cold, acidic yellow liquid poured out into Red’s mouth, pooling under his tongue and making his entire mouth sting just slightly as he gulped down his love's liquid waste, swallowing as quickly as he could, knowing what would come next.

Sure enough, even as the stream of urine continued to run from his vent Kiro felt his second sphincter release, and he tapped his mates head to warn him as he felt the internal swelling that meant he was about to defecate. He felt Red gulping faster and pushing his muzzle up into his crotch just in time to catch the first load of his solid waste. The soft, almost mushy feces spread his vent wide open, exposing the pink flesh inside for a moment before his excrement obscured it. Kiro's cock hung right in the center of his cloacal opening, right in the line of fire for his feces. Soft brown shit slid out from deep inside his body, flowing around his stiff cock, coating it in slick brown waste and mixing with the dark yellow urine still streaming from his slit, turning it a muddy brown, before dropping into Red’s maw. Kiro shivered at the sensation of the slightly gritty mass sliding over his shaft, the friction pleasuring him like a feline's tongue, mirroring his lover's joy at the musky feces dropping into his muzzle. Whenever the flow slowed at all Red pushed his muzzle harder against Kiro's vent and started licking and sucking the residue from his stiff cock, the precum liberally squirting from the tip adding a sweet aftertaste to the bitter, filthy flavor of the lizard's shit.

Kiro's bowels could hold a big load, so for almost two minutes the pair kept this position, Red voraciously gulping down whatever fell into his mouth, the foul taste of the reptilian feces arousing him more than anything and Kiro leaning back, eyes closed, enjoying the pleasures of voiding himself into someone else's mouth and being sucked off. He was starting to feel the beginning of a climax when the flow of feces abruptly stopped, his bowels apparently having emptied themselves. He heard a whine from his disappointed boyfriend and a tongue flicking around his vent, licking up the remains of his waste. He opened his eyes and sat up, propping himself up on his elbows, and grinned down at Red who was staring dejectedly at his crotch. Kiro wriggled his hips a little, making his cock twitch in a reminder that there was more work to do. Red's eyes lit up and a moment later he had Kiro's cock in his muzzle once again, happily sucking away at the brown-stained, scat-flavored flesh. After a couple minutes of loud slurping and moaning, Kiro came violently, yelping as his cock jerked and twitched, spraying a huge load of his thin, watery cum into his love's maw, where it was eagerly slurped down by the ravenous lizard. Red sucked at the stiff member for a few seconds, then slipped his muzzle off of it with a pop and watched it slip back into Kiro's vent.

Red climbed up on the bed and lay down next to Kiro, draping himself across the other reptile and laying his head on his scaly chest. Kiro smiled and nuzzled at his love's head. He could feel the mass of feces still filling his cloaca, and he could feel a draft that told him his vent was still gaping open. "You know, there's still plenty down there for you, hon'. And you haven't gotten off."

Red giggled and nuzzled into Kiro's chest, patting the bulge in his stomach. "I'm saving it for later, I'm full." Kiro chuckled and mumbled, "You're a weirdo, you know that?", then rolled over to wrap his arms around his boyfriend. Red accepted the embrace happily, humming his agreement as he hugged his love tight.
