Kevster: Origin edition
“OK, Chester! We’ll be back by 7 with dinner. There’s some cheese and crackers to hold you over just in case! Are you sure you don’t wanna come with us?” Yelled Mrs. Nutz from across the stairwell. 
“No thanks, Mom!” Chester replied. Chester’s parents and sibling were off to go grocery shopping and pick up some pizza, leaving the elder child behind. The brown hedgehog made doubly sure that he was the only one in the house before he got to snooping. Chester made his way down to the laundry room, and dug through the hamper filled with dirty clothes to find what he so desperately craved. 

“Ah, hah! There you are!” Chester exclaimed, holding up his younger brother’s used underpants. The clothing had the name “Kevin” written on the tag in permanent marker, so everyone knew who they belonged to. Taking a deep sniff of the interior backside of the undies brought Chester pure ecstasy. Rushing back up to Kevin’s room, Chester grabbed a very special candid photo he took of his brother’s naked butt. The picture was the closest he ever came to getting it on with Kevin. 

Chester had a raging boner for a while now, as evidenced by the tenting in his pants, which happened to be the same color as his skin. After dropping trough, he unleashed his pent-up horniness for the day on the dirty underwear. Chester grabbed his cock, and began pumping while using his other hand to hold the candid photo up to his eyes. *snnnnnnnfffffff* “Ohhhhhh, yeah! Your ass is so stinky and dirty, Kevin! And fat, too!” Chester said to himself. “What’s that? Oh, you want me to give your cheeks a spanking? Okay!” He added, smacking Kevin’s pillow. “Pllbt! Oh, Kevin! You gotta lay off the dairy!” He said, pretending the spanking triggered his bro’s flatulence, which also turned him on. “Oh, no Kevin! I don’t think I can hold it anymore!” Chester announced as he shot sticky ropes of semen on the center of Kevin’s underwear.

After admiring the seed he spilled on Kevin’s underpants, Chester still felt like he wanted more. He went up to the mirror, trying to gauge what the fuck just happened. “Did I really just do that?” Chester pondered. Lately, Chester was having some issues with his lust… especially for his younger brother Kevin; all day Chester got to ogle his sibling, and all night he got to fantasize about him. At this point, the two haven’t developed any sexual relationship yet. Kevin was completely oblivious, but Chester has been getting more and more pent-up as each day passed. It was at this point he realized… this was a two-player game.

After getting dressed again and restoring the room to its previous state, Chester kept on wondering how he’d manage to satisfy his urges. He narrowed it down to 3 choices. Option 1 was to molest Kevin in his sleep, option 2 was to trick Kevin into having sex by saying it’s some kind of game, and option 3 was to just explain what sex was to his five-year-old brother, but fail to mention it shouldn’t involve minors. Ultimately, Chester decided on option 3, since this was the only one that wouldn’t be considered rape, which he wasn’t really used to at that point. “Chester! Come down and eat!” Yelled his mother. 

At the dinner table, Chester was worried his growing sex-drive would lead to embarrassment, or worse, imprisonment. But he had to make his move in order to set his plan into motion. Said plan was to get him and his brother more connected, so they’d be trusted by themselves, and so Chester wouldn’t look like a pervert upon first glance. “Mom, can I sit next to Kevin please?” He asked. 
“Oh, sure. Why?” His mom responded.
“Just because…” Chester answered, hoping not to seem suspicious. The hedgehog got up and quickly moved to his brother’s left. “Hi Kevin~” Chester said to his target. 
“Hewwo!” The teal porcupine replied. “I wuv you!” 
“I love you too, Kevin!” Chester thought.

The very next day, Chester took Kevin to the playground. Over by one of the slides, Kevin wanted to go down face-first on his belly. “Push me, Chestew!” He commanded. Chester was surprised. 1cm away. That was the closest he ever got to Kevin’s butt without, y’know, anything sexual happening. For a brief moment, he lost all control and took a deep sniff of his younger brother’s rear, using his face to push him down the slide. As Chester collected his thoughts, he realized what he just did, and knew he and Kevin had to get the hell out of there and into somewhere more private.

“Come on, Kevin! We have to go!” Chester said, grabbing his sibling by the wrist and carrying him. 
“Why do we have to go?” Kevin asked. 
“I think it might rain today!” Chester replied, using the oncoming clouds as his “evidence.” Rushing back home, Chester told his parents he and his sibling would play in his room. Unaware of what was going on, his parents shrugged it off as simple wholesome brotherly bonding. Meanwhile, Chester went into his room with Kevin, and immediately locked the door. It was now, or never.

“What do you wanna pway?” Kevin asked. 
“I wanna play a this new game I just came up with. It’s a super secret game that you can’t tell anyone else about.” Said Chester. “It’s called ‘Sex’. It’s what two people play when they really love each other.” Making sure the blinds were down, and nobody else knew, Chester began taking off his clothes. “To play, you can’t wear clothes. Kinda like when you go swimming.” He explained. “When we take off our clothes, we have to compare our butts. Whoever has the smaller butt is the dom, and gets to do whatever they want with the other person’s bigger butt. The person with the bigger butt is called the sub, and they have to let the dom play with their butt.” 
“Otay! Wet’s compawe!” Said Kevin, taking his overalls off and showing his butt to his brother. “I tink my butt’s biggew. Did I wose?” 
“Haha, no you didn’t lose. I just get to play with your big butt.” Chester reassured. “Now lay down and accept it.” 

The brown hedgehog began eating his brother out, licking up and down Kevin’s dirty buttcrack while smelling it too. “Hahahaha, dat tickwes!” Said Kevin. After the cunnilingus, Chester began lightly smacking his brother’s buttcheeks. “These spanks are good spanks, Kevin. They mean I love you.” Chester explained. 
“Ohh, I tought dey didn’t huwt as much.” Kevin realized. Next, Chester decided to actually get his penis involved. Immediately Chester began hotdogging his younger sibling, and it felt amazing. Suddenly, Kevin felt some gurgling in his stomach. The pizza they had last night managed to take effect now, and the timing was almost too perfect. “Uh oh, Chestew. I tink I gotta bwast.” Kevin warned.
“Kevin, I’m gonna tell you a very private secret. You know how you always fart a lot when you have dairy? Well, I love that. I love your stinky butt, and your farts.” Chester revealed. “When we’re alone together, you can fart on me whenever you want, but not when we’re with other people. Got it?” 
“You… wike my bwasts? Otay!” Kevin replied, grunting a little before unleashing a monstrous blast right on Chester’s wang. *FRRRRRRRRBBBBBBTTTTTT* “Teehee, excuse me!” 
“Oh, Kevin that smells lovely! I think you won!” Chester said, cum shooting into his brother’s quills.

“I won?” Kevin asked. 
“Whoever makes the dom’s penis cum first is the winner.” Chester further explained. After cleaning each other up, Chester gave Kevin’s butt a kiss. “Dat was fun! Can we pway it again?” Kevin asked.
“Not for a little while.“ Chester said, laying down on his bed. “Your butt is fun to play with. But remember: don’t tell anyone else about this. Now get outta my room, babe.” Before exiting, Kevin thought that if Chester liked his butt, then he’d like his underwear too. “Wait, Chestew. Can you show me dese undies when you wanna pway sex again?” Kevin requested.
