Tuck’s belly groaned as he waited on the bus. He had eaten so much today and couldn’t wait to finally go home and relieve his stomach from the aches of all the food currently held within it. It will not be in the typical way you would relieve food, though. Tuck had other plans for his dinner. 
The bus stopped at his location and Tuck got off along with some other passengers. He held his belly as he hobbled over to the ordinary house that he’s been living in since he was 23 now. At 27 years of age, the fox considered himself fortunate that not only does he have his own house as a 20-year-old man in America, but also for his loving partner who he has been able to entrust all his secrets and desires with. It was this man who greeted him at the doorway he entered when he came to the door.ppy birthday! I hope you’re ready for today, because my stomach is ready to explode giving you what you want.” said the similarly aged gecko with beautiful bright green scales. 
“Let’s just go in and do this already, Cignus. I-urp. I’m really not feeling well. I don’t know how much longer I can hold this stuff inside me. I’m about ready to explode myself. Ate- *groan*- ate too much for dinner. Stuffed myself full of so many fries with my meal at a burger joint.” 
“Hah! How do you think I feel? I'm never into this sort of stuff but I ate all the last of the turkey and whatever else we had in the fridge just for you. I haven’t been feeling well myself all day either but I suffered through it just to be able to do this for you. Thankfully I'm not as full as I was a few minutes ago but my stomach is still only barely holding on. I don’t mind of course, It’s your birthday after all and I know you’ve been talking about wanting to perform your emetophilia fetish in real life and I want to give you the chance to be able to do that on your special day, even if I’m not too into it myself.” 
Tuck couldn’t disagree with that. Ever since he was a teen Tuck has had a fascination with vomit. While growing up during the “shock video” culture, it wasn’t uncommon for him to be shown a gross video from a friend of people performing disgusting acts such as shitting and vomiting over themselves. The videos never did truly hit him the way it hit his classmates though. While they would look at them in disgust, Tuck would watch with high curiosity. When he would go home, he would remember the videos he saw and return back to the websites on his family’s computer when no one else was around and rub on his little dinky. It took time for him to be able to masturbate to vomit solely, but over time as his interests grew and his depravity fell, he found himself more and more willing to undergo acts that others wouldn’t dare to cross or even think of when it came to their stomach contents. It wasn’t all the time he fantasized about it, but the few times the urge does get to him, he would easily spend a night alone on his computer jacking off to vomit videos and stories. He would even spend some days shoving fingers up his mouth and heaving his food into the toilet while jacking off. If the urge was big enough, he’d stand in the shower and spew sick all over his chest and cock and masturbate before cleaning himself off. It’s a fetish he has been careful not to express to others for fear of judgment. The one time he did try to tell a friend about his emetophilia fetish in high-school, he was looked at with a look of pure horror, but thankfully Tuck was able to play it off as a joke. Ever since then Tuck has kept his more disgusting interests under lock and chain. That is, until he met his boyfriend Cignus.  
Cignus, always so wonderful and loving to him. His boyfriend caught him during one of his shower sessions one time with vomit all over his body and he was immediately overcome with shame.  Tuck remembers screaming at his boyfriend to leave. He had never yelled at his boyfriend before that, but Tuck found himself caught in a vulnerable manner and couldn’t think rationally at the time. Cignus never did leave Tuck right away as he was expecting, though. Instead, he simply closed the sliding door and talked to him behind the screen, “I always knew you were keeping secrets from me, still. I noticed how you always seem to go and hide sometimes when we’re alone together, or avoid certain questions and take long showers. I want you to know that it’s okay, what you’re into. I don’t mind. I know you’re probably super embarrassed right now and don’t want to talk about it, so when you are ready come meet me in the other room. I’ll be there when you’re ready to talk about this, about everything.” and with that Cignus left the bathroom and left Tuck to his own thoughts. A thousand of them raced through Tuck’s head. He wanted to leave, to just leave this place and never return, but...his boyfriend was just so sympathetic to him right now. He didn’t judge him at all at the moment. Maybe, just maybe, they actually could talk and work this out. 
Communication was exactly what they did later that day. Tuck let Cignus know about everything he was into and Cignus agreed to try out new things with him, one at a time, so that he didn’t have to do it alone anymore. To say Tuck was excited would still yet be an understatement for his feelings that day. Over the coming months, they would enact his watersport and scat fetishes, both of which were tough for Cignus to overcome but he did it for Tuck’s sake because he loved him so much. Now, with Tuck’s birthday here, Cignus wanted to surprise him by doing gross vomit stuff as well, as he could think of no other better way to celebrate the day than by getting gross with his partner. 
“Come here!” Cignus dragged Tuck inside into the kitchen where Tuck was greeted by five one-gallon jugs of milk. “I’ve been busy myself while you were gone, I’m sure you remember those gallon milk challenges a decade ago and how people would often throw up before they could finish. Well, I figured we could make use of that challenge again to refill our stomachs once we empty them.” Tuck thanked him and Cignus proceeded to take off his clothes and sit down on the hardwood floor on his knees in preparation for what’s to come. “Well, I’m ready when you are.” 
Tuck kneeled down and took off his clothes himself. This was it, this was his chance to finally get what he’s wanted ever since he watched those disgusting videos long ago as a teen. He looked at Cignus’ spiky teeth, his pink tongue, his hidden throat and could only imagine what sick surprise waits beneath. He couldn’t hold himself back anymore and started kissing his lover. His enthusiastic tongue tossed and tumbled all around in Cignus’ mouth, tasting the sticky, long tongue common to his species. He lapped up all of Cignus’ saliva and took it into his mouth as his boyfriend reacted and did the same to him. The moans of kisses and the smacking sound of lips coming together and back off again could be heard through the house. On any other day Tuck would have been satisfied with just kisses as a foreplay method but he wanted more. He closed his eyes, grabbed a hold of the side of Cignus’ head and delved deeper, getting his tongue down into the entrance of his throat. He tickled his uvula, pushed past his tonsils, and slithered past his epiglottis to open his boyfriend’s throat and get a taste of his slimy esophagus.  
Immediately Cignus was awash with distress. His body started to convulse and heave as he focused on not throwing up, but found it to be difficult as he had never had anything down that far down his throat before. His boyfriend consoled him in a way, rubbing the back of his head while he licked through the entirety of his mouth. Cignus couldn’t hold back for long and the contents of all the food he stuffed inside himself, all the beans and tamales and burritos and cheesy nachos and spaghetti and milkshake, all of it came tumbling up and down out of his mouth into Tuck’s. 
Tuck’s ears immediately perked up when he started to hear his boyfriend hurl. He knew he was close to getting what he wanted and became more forceful with sliding his tongue deep down his boyfriend’s throat until he felt the upchucked contents empty out from deep inside of him. The vomit was deeply acidic and off-colored, barely resembling any visage of what it used to be going down, and Tuck loved it. He grabbed hold of Cignus’ face harder and pressed his mouth in deeper to try and catch all the vomit exiting Cignus’ mouth. The puke was extremely forceful and plentiful, filling out Tuck’s mouth in no time and charging it’s way down Tuck’s own mouth in no time. Tuck could just barely taste the remains of what Cignus must have eaten earlier as he devoured the vomit from his boyfriend into his own stomach. He found himself not even having to swallow, the contents of Cignus’s stomach was so strongly pushed against his own throat that it shoved its way in without him having to do any work. Not all of the vomit was able to be contained in their throats unfortunately and what little did come out dropped down onto their legs below. Tuck’s cock, which has largely remained hidden in his sheath until now, was at full mast and basking in what little vomit dropped down on it while Cignus’s cock was still hidden inside his slit, him not being into the action as much mentally as Tuck is. 
Cignus felt horrible. Puking took a lot of effort from your body and his throat burned as he emptied out his stomach’s contents into his lover’s. Since he ate so much it went on for longer than normal as well, but thankfully the vomiting did end and he had nothing more to give to Tuck as all the food he ate had been vacated from his body now. He felt relief in the thought that it was over until Tuck gave out hacks of his own and threw up again into his mouth! Suddenly all the disgusting vomit he had just emptied out of his body came rolling right back into his stomach along with the food Tuck himself had earlier. He tried to break free or stop the assault with his tongue but Tuck was holding on too strongly and the food assault was too fast for him to block before engulfing it down. 
Tuck tried to keep all of Cignus’s stomach contents down in his own, but as it turns out the hefty meal he had earlier along with the hard to swallow contents of another’s vomit made that an impossibility and soon after Cignus was done hurling down his mouth his hurled back into his. He hurled and hurled until his own stomach was emptied while keeping a strong grip on Cignus’s head still. Despite the disgusting nature of their acts, Tuck still did not want to let go of his boyfriend as he remained horny. His dick was hard and leaking at this point and he wanted to go even further and be even filthier with their acts. So, even though Cignus strained and tried to evade his grip, Tuck kept him there as he let his instincts take over. He was starting to no longer be himself, but rather an animal fed only by their lust. A lust for vomit. It was this reason why he was glad that Cignus once again hurled his stomach contents back again into his mouth that he could swallow again and continue to mess around with. Both lovers continued on like this for a duration of time, vomiting in each other’s throats. What was emptied in one throat was soon forced back in by the other and vice versa as Tuck and Cignus had a sort of tango with their vomit. The few liquids that didn’t get hurled into someone’s throat each time they vomited continued to be emptied down below onto their knees beneath them.  
Eventually there was enough vomit to have escaped onto their legs and the floor below that what remained was manageable. Tuck’s throat was the first to give out, having a bigger fondness for vomit and with his interior muscles getting tired after all the heaving. With one final hurl, Cignus emptied out the remains of his stomach one last time into Tuck and Tuck admitted defeat, having no strength left to hurl again in that moment. Tuck let go of Cignus and both stared down at the mess on their bodies and then looked up again and laughed. 
“Looks like about half the food’s all over us now,” said Cignus. 
“Yeah, and the other half is still inside of me, which I’m fully going to pay you back with,” said Tuck. 
“What? What do you mean pay me back?” Cignus didn’t have to ponder for long. Tuck got up and shoved two fingers up inside his mouth, a concept he was much familiar with. After a few deep penetrations of his throat he vomited the remainder of their meals onto Cignus below. Cignus could only close his eyes and bow down to the shamefulness of being thrown up on. His bright green scales become more slick and dirty looking with the light brown deluge being vomited upon him. His senses were tainted with the sickly smell of vomit and his wide open ears were filled with the mess. He could feel the puke falling down from his head to his toes. Yet, when Tuck was done, he looked up and smiled at his lover all the same, letting him know that despite their sinful acts, he still loved him and supported him in their acts today. 
“Well, I’m definitely going to need a shower after that!” Cignus chuckled. “Here, let me grab one of those milk jugs and pay you in return.” Cignus stood and reached over to the table. He swigged one of the gallons of milk up promptly. Neither of them had trained to be able to successfully swallow an entire gallon of those things which means there would be no worry about not being able to vomit it all back up later. It took a couple of minutes but the milk eventually did pile on and stretched his stomach enough that he couldn’t keep it in his body anymore. When he felt as though he couldn’t swallow another drop, Cignus let go of the bottle and told Tuck to get on his knees, which he did. 
Tuck was excited! He was going to finally be fully covered in vomit that wasn’t his own for once, not including the mess already on him. He waited eagerly as Cignus forced himself to drink the gallon of milk past his limits and then in one quick motion: remove the jug from his mouth and puke it all over Tuck. Tuck was much more enthusiastic about being vomited on than Cignus was and was rubbing over his body while being vomited on as though it was some sort of sick shower for him. The vomit was much more white this time, having no time to combine with the contents in Cignus’s stomach before he threw up. It made for a lovely white rainfall of milk that Tuck rubbed in between his armpits and buttocks and over his chest and body. He would slide some of the milky vomit over to his penis and stroke off while lapping some of the puke that fell out of Cignus’ mouth into his own. Cignus could hardly believe what he saw; there was just no way someone could be so into vomit, but he supposed it was better not to question at all when it came to the acts of some people.  
After Cignus was done puking up his contents on Tuck, he sat back down, exhausted from the effort of his abdominal muscles in having to heave up so much. “Tuck, I need to take five, you go find some other way to play with vomit for now.” 
“How about your ass, can I play with your ass?” asked Tuck. 
“Uhh, sure.” Cignus figured Tuck would fuck him for a bit to get off which he was certainly fine with, but Tuck had other plans.  
Tuck went down to Cignus’s dark and murky ass and licked all over it’s swampy taste. Ever since Tuck came out to Cignus he has been more lax in his showers which meant that Tuck often had stale ass-mud and strong odors to deal with which he of course loved. He would spend many days doing nothing but sitting underneath Cignus’ tail and cleaning his ass out. He chomped down on any caked shit covering Cignus’s ass and licked up the tiny specks that remained. Cignus moaned in delight. Despite his boyfriend’s many unusual and strange interests, getting rimmed is one of the few vanilla acts he did enjoy. When Cignus’ ass cheeks were clean, Tuck inserted his long tongue into his rectum. He was promptly greeted by long, thick brown shit that filled up Cignus’s insides. Cignus often never used the toilet much anymore either, opting to use his boyfriend instead when he came home. He loved it best when he had to go while playing a game or laying on the bed and having his boyfriend right there to dump his waste down into. Though Cignus could never truly understand the fetish himself, he sure did love essentially having a portable toilet most days.  
Tuck performed his duties as he usually does, breaking up the large shit log into smaller pieces and taking them into his mouth. Being a gecko, it was not uncommon for Cignus to be snacking on insects as part of his meals. This typically made his shit more difficult to eat as Tuck is a fox and dried, digested insects were most certainly not part of his diet, but he was determined to perform his task as good as any toilet would be. He reached his snout in further and used suction motions to gather up what shit logs he can into his mouth and eat them up. Once the shit was in his mouth he worked his mouth muscles overtime to be able to chew up the digested food into something worthy of being able to be swallowed and digested again. When he ran out of shit in Cignus’ ass, he would delve his snout in further and repeat the same process. It was a good thing Cignus’s tailhole was so loose. They were both switches but Cignus preferred to be the bottom on most days and when Tuck was not around or too tired to perform for Cignus, he would bring out his extra large toys to play with instead. This resulted in a very loose ass over the years and Tuck was easily able to fit his entire snout into Cignus’ ass to gather up all the shit chunks he could. He did eventually run out of shit to be able to eat though, but when he waggled his tongue further in Cignus’ large intestine he could feel more shit hiding inside still. Tuck wanted that shit and he had a plan to get it. 
Tuck removed himself from the now clean hole of Cygnus and reached up for another jug of the milk containers they had. He swigged the bottle down, filling out his shitty stomach with the milk contents now. Much like Cignus earlier, Tuck could barely get the entire bottle down without puking, and when he did eventually feel like he was at his wit’s end with keeping all his stomach contents down, he tossed the bottle aside and reinserted his muzzle into Cignus’ ass where he proceeded to vomit inside the ass of his lover. 
Cignus loved feeling his boyfriend rim him and eat his shit out. When he felt him remove his muzzle he thought that was it. He saw his lover grab another gallon of milk and drink it down voraciously and thought that was strange but just assumed that maybe he wanted to puke on himself again. His innocent mind wouldn’t have let him imagine any other possibilities, so when Tuck tossed the jug and inserted his muzzle back into Cignus to vomit inside, Cignus was caught off guard and yelped at the indescribable feeling of having puke shoved up inside of your ass. He tried to move himself away from the action but his lover was quick to grab ahold of his legs and keep his muzzle firmly in his lover’s ass. Cignus’ intestines built more and more pressure from the efforts of Tuck’s muzzle puking inside of it and he could feel the sick curling around inside of him and reaching up into his small intestine. He couldn’t take it anymore, he was okay when it was just them vomiting into each other’s mouths but something about having vomit in his ass was just too much for him. He figured if his lover was going to be into vomit so much then he should be able to handle what he can dish out and he proceeded to squeeze with all his might and shit the vomit back down into Tuck’s mouth.  
Tuck was excited! He was hoping his lover would crap the puke back into his mouth and he actually did. The off-white milky vomit that he upchucked into Cignus’ ass came rolling back down into his mouth along with the shit that was held deeper inside that he couldn’t get to. He mastized the shit into edible chunks and swallowed it down along with the sweet milk. The contents combine to make a murky half-solid with a consistency much like a thick milkshake. What would normally be a tough swallow for Tuck was made better by the milk accompanying the shit. It gave the feces a sweetener to its taste which allowed Tuck to be more passionate than ever about swallowing the forbidden brown mud down. 
After Cignus emptied out his bowels and Tuck had swallowed the contents of his insides from both his mouth and ass now, Tuck raised up and looked at his lover, “Dude, I freaking love you! That was amazing!” 
“Yeah, well, don’t get used to it. I don’t particularly like having your vomit inside my ass. Also, warn me next time before you do something like that.” Cignus stated. 
“Heh, okay I will. Look, I’m sure we’re both getting very tired from all the vomiting now so how about just one last act to end off the day.” 
“Sure what do you want?” 
“A vomit 69. I want to feel you puking all over my dick to make me cum, bro.” 
“Hmm. I’ll do it, but you better hold off with your vomit until I cum because I can’t guarantee I’ll be able to do it with your puke all over my dick.” 
“Deal!” And with that, Tuck got himself a final jug of milk and handed one over to Cignus. They did the same acts as before, swallowing up much of the milk until their stomachs swelled and then proceeded on with the oral session. Cignus placed his mouth upon Tucks’s still-hard shaft while Tuck had to stuff his muzzle inside Cignus’s slit and coax his slender, tapered cock out. 
Cignus was having an easy time with Tuck’s shaft. He’s sucked it many times before so he knew just how well to please Tuck and deepthroat it without any trouble. This time, when he tried to deepthroat however, Cignus’ stomach contents came hurling out onto Tuck’s cock. He grabbed onto Tuck’s knot as leverage and spewed volley after volley of milky vomit onto Tuck’s shaft. When he was done, he took off from the cock to catch his breath a little before returning back to sucking on that deliciously long, thick shaft of the fox. Despite being covered in puke, it wasn’t so bad sucking the cock since it was mainly just pure milk now, and it helped give the cock a candy-like taste as he slurped it down. He could feel his lover’s cock throb hard before erupting into his mouth. No surprise there, he was sure his lover had to have been pent up as hell as is, having played with vomit so much today. He swallowed down the thin liquid and translucent cum into his mouth, the salty taste washing away along with the rest of the remaining milk in his mouth. 
Tuck swore he came harder than he ever had in his life. He saw stars appear before him as his nuts gave out their final farewell to the intensely hot session they had today. He barely wanted to even do anything else for the day after that nut, but he knew he owed it to his lover to at least make sure he got off as well, so Tuck made good use of his mouth to reach deep inside and lick along the gecko’s shaft. Unlike Cignus, Tuck had to make sure the gecko came first lest he gets vomit all over his dick and ruin his whole mood. Tuck wasn’t feeling good though; his body was fed up with all the vomiting and seriously wanted all of his stomach contents out right now so the fox had to work fast before he lost all the milk inside of him. As soon as the slightest sliver of cock appeared from Cignus’ slit, Tuck formed his mouth into an O-shape and gave the hardest, most eager suctions and licks he had ever given in his life. The performance immediately got Cignus’ attention, who moaned again and started to get into the sex again.  
Cignus had never felt his lover suck his cock so hard in a long time. Whether it was because he wanted to get it over with before he puked or as thanks for the vomit-filled pleasure day he helped provide to the fox, he didn’t know or care. All he could think of soon was getting his rocks off and nutting in that slutty mouth of the fox’s. Cignus grabbed both sides of the fox’s face and thrusted hard into the fleshlight mouth of his for all he was worth. He was very pent up himself, having not been able to get off himself and being a little frustrated at not being able to get horny much during the vomit-play. Well now he was ready to relieve that frustration of his into the willing mouth of the fox and give him what he deserves. 
“Aghhh! Take. My. Fucking. Nut!” Cignus yelled. 
Tuck had to really focus to not vomit. It was all he could do to hold on. When he finally did feel the spurt of Cignus’ thin, streamy cum come out, he finally let go himself and hurled huge bursts of vomit all up and around Cignus’ cock. 
Cignus could feel the vomity mess coming up and around his cock but he was at the point of no return now. He climaxed hard into the deluge of spray that was Tuck’s vomit. He was impressed with how much Tuck was able to vomit. By the time his climax ended Tuck was still erupting many waves of vomit from his mouth. Cignus just lied there feeling the spews of vomit on his cock as they gradually got weaker until there was nothing left. 
With both furries now fully emptied, it was time for them to sit up and stare at the mess they made around them. Their entire bodies were covered in vomit. They smelled like sewage, they looked filthy, their tongues tasted like acid and cum (and shit in Tuck’s case), and what was once a polished clean wooden floor underneath them now had a layer of vomit on top of it. 
Despite that, when Tuck looked at his lover there was only one question on his mind, “Can we do it again?” 
Cignus just groaned and layed back down.
