Gassy Tails
Ch.1: Tails's First Date
Tails stared fondly at the girl sitting across the table from him. He still couldn't believe that he was actually on a date. Sonic had been pushing him to get out more and had thought that this was the best way after the threat of the Metarex. Thanks to the hedgehog's nagging, Tails had finally worked up the courage to ask out Cosmo. He had been a stuttering mess when he had asked her out and was really surprised to hear her say yes.  Even though Tails wasn't bullied anymore, he often thought back to the kids calling him a freak when he was younger. Constantly hearing those words in early life made Tails believe that no girl would ever be interested in him but here he was. 
"Thanks for doing this, C-Cosmo." Tails said with a smile.
"I wouldn't miss it for the world." Cosmo said, reaching over to hold Tails's hand on the table. 
The Seedrian continued to talk about her day and how happy she was for the date, but Tails was having a hard time paying attention. Pulling on the collar of his tuxedo top, the fox was trying keeping his nerves in check. Sonic had told him everything would be fine, but Tails didn't want to do anything to ruin his date. Especially since Tails knew what always happened when he got nervous.
Gggrrr
Uh-oh, Tails thought.
"Could you please excuse me for a moment?" Tails asked, knowing he had to get to a restroom before things got worse.
"Oh...sure." Cosmo replied, in slight confusion.
"Thanks." Tails immediately got up from the table and speed walked to the nearest restroom. As soon as went inside, Tails waited for the doors to close before he flagged his tails and grunted.
PPPPFFffrrrt
"Ahhhh....that was close." Tails said in relief, wagging his twin tails lightly. He then realized he wasn't the only one in the restroom.
"Whew, boy what did you eat!? I know this is a bathroom, but jeez!" Said someone inside a stall.
Tails blushed madly, knowing that he had just unleashed an eggy stench on an unsuspecting victim.
"E-Excuse me." Tails said, before running out of the restroom. He really hoped that was the end of his gassiness, but as the fox rubbed his tummy, he had doubts. Everything was better when he saw Cosmo's smiling face when he returned to the table.
"Sorry about that. I needed to...wash my face." Tails said as he sat back down. For some reason he felt out of breath, but he thought it was just nerves
"But your face isn't wet." Cosmo said.
"Oh! Uhhh....That's because....they've got a good fur dryer in there." Tails lied, still not wanting Cosmo to know what he was doing. 
"Awe Tails, your so cute. I went ahead and ordered for you." Cosmo said with a smile. Tails breathed a sigh of relief when she changed the subject. However, his mind wasn't the only thing that needed relief. 
GGGGGRRRRRLLLLLLL
"Ugh!" Tails grunted as a new gas bubble formed in his tummy. And unfortunately, it was much louder than last time. 
"What was that?" Cosmo asked, looking around. She was so thrown off bu the noise, she didn't her boyfriend’s obvious distress. But in her defense, the noise sounded like a dying seal. 
"Ngh, I didn't hear anything." Tails said. He was about to excuse himself to the bathroom again, but their food had arrived. Tails was caught off guard when a bowl of chili was placed in front of him. 
"Oh...you got me chili?" Tails asked, forgetting about his tummy for a minute. 
"Well, you like Chili dogs, so thought you'd like this." Cosmo said with a smile.
"Gee...Thanks." Tails said. He gave Cosmo a nervous smile before staring at the bowl of chili. Under normal circumstances, the fox would have happily digging in, but chili was the last thing he needed right now. However, Cosmo was so sweet to order him something and he really didn't want to make her feel bad for the gesture, so against his better judgement The fox hesitantly began eating.
"Mmmm." Tails moaned as he swallowed the first spoonful. The chili was super tasty so he kept eating it after Cosmo started eating her food. However, as good as the chili was, it was also really spicy, which Tails didn't mind until his tummy reacted.
GGGGGGRRRRRLRLRLRLRRLRLR
"Oh no!" Tail said as his tummy rumbled in pain. It took everything in him to keep his tails from flagginf and releasing the gas that wanted so bad to be let out.
"Are you okay, Tails?" Cosmo asked in concern. Her boyfriend was in obvious pain and she could see his tails twitching as he started sweating.
"I-It's nothing, I just gotta run to the restroom real quick!" Tails said. The fox left the table before Cosmo had a chance to say anything. Tails went straight to the bathroom, but just as he was about to walk in a large bear in a gas mask walked up to him. 
"Woah there tiny. This bathroom's outta order. Some hooligan must've dropped a stink bomb in da toilet, and now we gotta air it out." The bear said in a very intimidating voice.
GGGGGGRRRRRLBLBLBLBLBLBLBL
"Ugh...B-But, where am I supposed to go?" Tails asked. His tummy was telling him he had to do something fast or else his day would get a lot worse. However, The bear only gave a  shrug, so Tails walked back to his table. When he sat back down he tried his best to calm down his tummy. 
GGGGUUUUUURRRRRRGGGGGGGLLLLLLEEEE
"Tails?" Cosmo asked, even more concerned now that the fox's namesakes were starting to twist. Tails, for his part was in too much pain to respond. He was at the point of no return and knew he needed to go somewhere else to unleash the beast inside his gut.
"I-I'm sorry, but I have to leave." Tails said. However, as he got up to leave Cosmo grabbed his arm. 
"Wait, why? Did something happen in the bathroom.?" Cosmo asked as she tried to stop the fox from leaving. Tails hated making Cosmo feel bad, but he just couldn't bring himself to tell her about his problem. And his tummy felt like it was on a mission to make things worse. 
GGGGGRRRRRLLLLLLLggggrrrrlll
"I-I...I Just..." Tails said as sweat started pouring into his tuxedo top. He tried to pull away, but the girl grabbing onto him with both hands. Now the couple's tug-of-war gathered the attention of everyone in the restaurant, which made Tails blush. 
"C-Cosmo, please...I'm gonna..." Tails stammered out quietly. He could see all the animals starring and tried to defuse the situation while still trying to escape before it was too late.. But Cosmo refused to drop the issue.
"Just tell me what's going on, Tails!" Cosmo yelled as she gave one final tug. Tails was sent crashing into their table and his tummy landed hard on the wood. At the same time, Cosmo landed face first onto her dates butt, which was unfortunate because of what happened next.
PPPPPPPPPPRRRRRRRRRRRRRRRRFFFFFFFFFFFFFFFTTTTTTTTTTTTTTTTT
Tails's tails and coatails fluttered wildly as the fox uncontrollably released a deafening fart. The other restaurant patrons shrieked in horror as a massive cloud of fox gas covered the area. Several mobians left the restaurant in a flash and retreated to the clean outside air. Even the Bear with the gas mask couldn't withstand the overwhelming stench of rotten eggs and beans. The smell was worse for Cosmo, who could almost taste the spicy sent emitted from Tails's butt. She fell backwards in shock as she finally realized what Tails's problem was. 
"Aaaaaaahhhhhhhhhh!!!!!" But right now, Tails was moaning in pure bliss. His tummy felt a thousand times better and the relief was so good, the fox completely forgot where he was. It wasn't until he opened his eyes that Tails remembered who was on top of him.
Gasp
Tails immediately turned around and saw Cosmo, causing the fox's heart to stop. Tails stared at his date for a long time as his face grew a shade of red. Cosmo could also see tears filling Tails's eyes. When the silence got too uncomfortable, Tails spoke up.
"Um....I'm so sorry." Tails said right before he got up and ran out of the restaurant crying. He was so humiliated that he just wanted to crawl into his bed and die. While he was running the fox didn't notice that his butt was still active. 
PRRRRRTTT
PPPRRRRRFFFFTTT
FFRRRT
Cosmo looked on as Tails ran off. She would have gone after him but seeing him fart more caused her to burst into laughter.
"Hehe, that fox is so cute." Cosmo said, as a blush formed on her face. She never knew mammals could expel gasses like that, but she had to admit it was hilarious. She only wished Tails wasn't so embarrassed, because she really wanted to see him do that again.
