A/N: I decided to make this a multi-chapter story, so there will be multiple days. Also Christian Ape99, it depends on who/what the characters are, I will need specific information.

Summary: Sonic and Kei, despite being boyfriend and boyfriend were okay with a certain someone having fun with Sonic, after all friends with benefits worked in their favor. Heck it made their times together all the more fun, and hilarious in Kei's opinion. When Jimmy comes, Sonic is in for an embarrassing and smelly day.

Disclaimer: I own nothing. Though I'm thinking of calling the couple of Sonic and Kei: BlueShipping, unless that name has already been taken, in which case I'll call it something else; and SpikeShipping, again, unless that name has already been taken, In which case I'll call it something else.

If you want to know what Kei and Jimmy look like, go on Google and search "Kei Ape Escape" it's the 1st picture, and "Jimmy Ape Escape" It's the 1st, and 2nd pictures.

Chapter 1

Sonic was having a good dream, a dream about Kei feeding him chili dogs while rubbing his belly. This dream would've continued had he not felt pressure on his face, and something framing his cheeks, nose and mouth. Opening his eyes in confusion he saw blue jean clad butt on his face, and before he could do anything a big fart was blasted onto his face, it only got worse when the smell kicked in.

"MMMPPPPHHHH!" Sonic was thrashing about on the couch, trying to get the person on top of him off of himself, and escape the smell. Another fart was let loose on his face, increasing the hybrid's struggles. After a solid 2 minutes his struggles ceased, and the person got off of him.

"Ah, those chili dogs really hit the spot cobalt." Sonic's eyes widened as he tried to fan the smell from his face, and looked up. There was only one person who called him "cobalt". It was Jimmy, Spikes cousin, and Sonic's "friend with benefits". Said boy burped in content with his handy work, and smiled at Sonic.

"Hey cobalt, had a nice dream?" the 14 year old brunette asked in a joking tone. Rolling his eyes Sonic replied in a monotone voice.

"I was before you sat and farted on my face cricket." Jimmy blushed at Sonic's nickname for him, but soon regained his posture as he retorted in a cocky tone.

"Well, you better get used to them, cause I have plenty stored for what I have planned later." As he said this, he turned around and shook his butt tauntingly at Sonic, completing his taunt with a pat to his butt.

While this happened Sonic blushed and gave his own cocky smile showing that he accepted Jimmy's challenge. But he also noticed something: he was back in Kei's house, on the couch. But he soon realized that he must've fallen asleep.

*FLASHBACK*

Sonic and Kei were grappling the other, trying to pin the other to the ground. Sonic was slowly gaining the upper hand, but Kei had a trick up his sleeve. He let Sonic's face get close to his own, and burped in his face. It was so sudden and the smell caught him so off guard that Sonic was pinned to the ground faster than you could say "oops".

Kei was smiling at his downed boyfriend and simply said.

"I win."

Sonic passed out soon after; he woke up when the full moon was at its highest peak. Kei was laying down on his stomach, with Sonic's head lying face down on his jean clad butt.

"About time you woke up Blue" he had paused to let loose a fart in Sonic's face "I didn't know my burps were THAT bad." At first Sonic moaned in disgust, but soon dug his face out of his others butt.

"They aren't, they just caught me off guard." Kei rolled his eyes, got up, dragged Sonic over to the tree, sat down and hugged him close; to the point where his face was resting on his chest.

The rest of the night they gazed at the stars, with the two cuddling together. Sonic spoke with an even tone in his voice.

"I love you Kei-Kei."

Kei looked down at Sonic, smiled, and said without a hint of doubt in his voice.

"I love you too Blue, never forget that." He kissed Sonic's forehead, and Sonic soon fell asleep.

*End flashback*

Sonic was brought out of his flashback when Jimmy's butt appeared in front of his face, and he caught a whiff of his last attack on his nostrils.

Sonic recoiled in disgust, and tried to fan the stench from his face; before he could get his payback though, Kei walked in.

"You two aren't starting without me are you?" He finished his statement with a pat to his stomach, and the two cringed in response at they had not so fond memories of Kei's farts.

"Nah, just giving cobalt a whiff of what he'd be getting." Jimmy responded in a cocky tone.

"Well then, all we have to do is agree; same rules as last time?" He asked in a mocking manner, as they always used the same rules. There didn't even need to be an answer as they sat down on the ground, ready to see who would win this time.

*1 HOUR LATER*

Kei was on the couch drinking a soda, he had purposely lost so Jimmy could have his time with Sonic. He didn't mind, none of them minded. Plus it was funny to see Sonic take fart after fart to the face.

Sonic soon tapped out, and Jimmy farted one more time and got up, smiling at his victory. He turned to Kei.

"You mind if I?" He didn't need to finish as Kei nodded in approval. He picked Sonic up, slung him over his shoulder with his face dangling in front of his butt, and went to Kei's room.

Sonic soon woke up and was greeted with Jimmy's bare butt in his face. He looked over his shoulder to see Sonic was awake and smiled.

"Told you I had plenty more in store for you." He brought his butt closer to Sonic's face "You know what to do."

Sonic, despite being in a relationship with Kei, still had feelings for Jimmy; and Kei knew this. All three of them never minded this. Sonic and Jimmy were perfectly content with being friends with benefits.

*THE NEXT DAY*

Sonic woke up from a burp to the face, and saw that he was in Kei's bed with Kei on one side of him, and Jimmy on the other side of him. Jimmy and Kei kissed him on his right and left cheek respectively.

Jimmy spoke into Sonic's right ear and asked.

"You want to "play"?"

Sonic blushed and nodded.

A whole day of being boys, lovers, and friends with benefits; and it was going to get much "sweeter".
