He quickly started looking for clues, unfortunately he couldn't find much, just crumbs that led nowhere. His head then began to think and rule out culprits, Leafeon could be the most obvious choice but he was always too busy doing his plant things to eat his sandwich, besides why would he want it if he could make his own gluco-thing. Then there were Espeon and Umbreom who were doing their gay thing so they were also out. Vaporeon wouldn't eat his sandwich since it had tuna and that would be... cannibalism? Well neither does he, Glaceon was away a few days ago on a trip of I don't know what, that only leaves Flareon, Sylveon and Eevee.
"Very well, then first I'll goooo fooor... I think Flareon is the least likely, so let's see" he ran like lightning to his fire-type brother's room and hit it with desperate force to make him open it... but no one responded, he tried again with the same result, so he opted for the most reasonable option... throw the death of a head.
For reasons of logic, he only broke it a little but ended up inside seeing his brother sleeping in a very... emm...
"mmm~" he moved in his sleep while letting out a tight and hot -prrrrrrrt- that accompanied his goofy smile.
"Hey, fat ball, wake up, you have to clarify a couple of things for me" Jolteon's face was wrinkled and no wonder, his brother not only had a very powerful stench, he was sweaty, making noises and had his "little friend." above, Jolteon touched him continuously, he yelled at him but he just didn't wake up, so he tried several things, a finger in his ear? Giggles, opening his eyelids? without response, he even spanked him with his electrified paw but only earned an "oww~" and a -PRFRFRT- that stunned him momentarily, Flareon could knock him out just by making him sniff his crack and without blowing a single fart. then he simply used the last resort.
"Well, don't blame me for this little brother, you're a heavy sleeper." Jolteon simply turned Flareon on his back and levitated his butt above his face, the tension felt like a storm was brewing.
"WAKE. UP. NOW" with a shout, Joilteon jumped and his butt fell onto Flareon like a meteorite and then...
-PRPPRPFRFRFRFRRTTRTRTRFRFFFFTRRRRRFTFTRRFFFFRRRRrrrrrrtrr-brrz-brz-b r-
Jolteon's butt sank and completely engulfed Flareon's head while subjecting him to a lightning storm of gas, without mercy, Jolteon took his time.
-BRBttBRRBtbbtrvb-
After a while he simply waited for a reaction from his brother, now completely still, at least until he felt something... funny on his butt, like rough and wet. Then, a templer walked over to Jolteon and jumped off his brother to see that he had licked his anus viciously in his semi-conscious state, which he found disgusting and somehow funny.
"Ugh, this is impossible, Flareon is having his wet dreams to have been the one who ate my sandwich, I'll have to try my luck somewhere else" he then headed to the door while rubbing his anus in an attempt to clean the saliva and his brother's sweat. He could see before leaving how Flareon simply turned around in his bed and raised a paw out of instinct before closing the door.
"mmmfh yeeees~ lick it... deeeper~" the fire type moaned before a -PFFFFFRFRTTRTRTR-
Who are you going for now huh?
