"Alright. You boys be safe now," our mother called as she left for another of her trips.  As soon as she left, I wrestled my kid brother to the ground and licked his muzzle, kissing him with affection.  
	He laughed and easily fought off my half-hearted grapples, lapping back eagerly like the two puppies we were.  "Mom's gone.  You know what that means!"
	I smiled because I did.  "I'm in charge."
	My brother, Hunt, returned the smile, "for now."
	The two of us had a very interesting relationship.  He was 8, and I was 28.  We were born so far apart that I'd been babysitting him for as long as my parents had.  Because he was still my little brother, he was curious about the things that I was interested in.  He tried to play the same games as me.  He tried to watch the same movies as me.  He liked to be like me.  Once he'd learned to read a few years ago, things had gotten a little weird between us.  You see, I am into humiliation.  He'd come across stories on my computer about babysitters becoming the baby and wanted to do the things in the stories.  
	At first, he thought it was a game.  I tried to dissuade it.  I knew what I was doing was weird.  He kept insisting as he got older and I kept assuming that one day our parents would find out about me.  As months passed, he never told them.  When asked why, he said that it was because mom and dad never found out when he'd wet the bed all those times because I'd woken him up and changed him.  So, I did something that I never thought I'd do - I let him take over, slowly.  It started with little things - letting him continue to read the stories and then doing little things from the stories that would key him in - like making peanut butter jelly sandwiches and then getting a mess all over my face.  I would never dissuade him from making fun of me because I loved how it made me feel.
	Then, he started taking the initiative on his own.  One time, I'd spilled a glass of water on my crotch.  My brother saw this and stopped me from cleaning off.  Instead, he pointed me over to the couch and had me drop my pants.  I barely had time to ask what it was for before he started spanking me and chastising me for 'wetting my pants.'  My dick had gotten rock hard from the spanking, but despite his size, he still managed to get a few good licks in.  I was whimpering in need when he sent me into time out in the corner.
	Since then, small little events happened here and there whenever our parents were gone.  Hunt seemed to love these interactions.  In fact, recently, he'd gotten even more like me in that his own cock had begun to tent during our play time.
	Today was different.  Usually, our parents were never gone for more than a few hours.  This was the first time that they would be leaving the house for vacation since the start of our interesting relationship, and my brother told me that he had plans.  I was excited for them.
	"Let's play a game!" he called out excitedly as he climbed to his feet from the cuddle pile.  
	I smiled and played along, "what kind of game, little guy?"
	The wolf cub gleeked mischievously, "Consequences!"
	I tilted my head at the cub, intrigued, "And how do you play that game?"
	Hunt smiled, "we each make a rule for the other person and the person who breaks it has to follow a new rule that is like the previous one.  For instance, if you don't bark like a dog on command, then you have to eat from a dog bowl!
	I blushed at the example he gave, and nodded.  "Fine.  Then your rule is that you have to go to bed before midnight every night."  I purposefully made his easy to keep while still being responsible.  I didn't want to actually have to punish him, after all.
	"And yours is that you can only pee in this!" Hunt said, holding up his little potty from when he was younger.  
	My face turned beat-red and I took it from him, flustered.  We each had our bets and agreed to them, but we had a whole summer to make good on them.  Even so, I had to pee right away, and the excitement was getting to me.  I went to the corner of the room with the potty and tried to get as close to it as I could before letting loose a stream from my hard dick.  I let out a shrill bark and whimpered, trying to undo it as the stream split, going almost every other than the potty.  When the stream finally got under control, there was already pee on the floor, the wall, and the seat, but only a tiny amount in the potty itself.
	Hunt picked up the potty and shaked his head, "looks like you already broke the first rule.  And since you can't even use a baby potty yet, it's back to diapers for you!  The second rule is that you have to wear diapers!"
	"Wh-what!?" I declared, secretly loving the sudden escalation.
	"Now clean up your mess before we diaper you up!" he declared, pointing to the wet spot in the corner.
	I whimpered and nodded, getting a few wet rags and soaking down the mess that I made, incredibly humiliated and frustrated the entire time.  When I finished and deposited the rags into the wash, my brother was standing by with a large baby-printed diaper in his paw.  He'd found my stash in my car!  He bopped me on the nose with it and ordered me to our bedroom.  However, as I started to get onto my bed, he stopped me and instead pointed to his racecar bed.  I blushed but flopped down onto the barely-large enough mattress, stripping down to naked with my cock flopping around in the air fully for him to see.  I could see his own little tent formed as I lifted my ass and allowed him to diaper me.  He wasn't shy about dumping the baby powder on me, filling the air with a babyish scent as it was spread all over my crotch.  I bit my lip as he used his paw to spread it around my cock, thankful yet frustrated when he finished and taped the diaper up around my waist.  
	"Nappy bye time," he declared, cuddling up next to me and rubbing my tummy.  Inwardly, I tried to resist, but he knew me very well.  As soon as he started stroking my stomach, my eyes grew heavy and the small bed didn't bother me.  
	
	When I woke up, he was asleep in my arms and it was in the middle of the night.  I needed to go, but I couldn't move without disturbing him.  It was fine, anyway.  I was diapered.  Letting out a low sigh, I huffed as I began to fill my diaper with piss, allowing the warmth of the padded undergarment and my little brother's embrace to take me back to dreamland.
	When I woke up again, it was because of a very urgent need from my crotch.  Hunt was feeling around down there and it was making me incredibly horny.  "Awww.  You're wet!" he declared, still mushing the front of the diaper.  This was the first time that he'd ever seen me actually wear one, after all, let alone wet one.  "It feels weird!  It's all squishy!"
	I whimpered as his paws kept exploring and I panted, resisting the urge to buck into his paw.  
	"But first things first.  You broke rule number one again!"
	"What?" I asked in a haze, not quite fully to my senses.  A few moments later, I realized what he meant.  Rule number one was that I was supposed to use the baby potty.  I'd gone in my diaper.  I'd only assumed that I was allowed to use it.  Whimpering, I folded my ears, not knowing that I'd subjected myself to another rule.
	"After we get you changed, I think we've proved that you're not fit to be the older brother or my babysitter.  That means that rule number three is that you're the younger brother now.  That means that I'm in charge, got it?"
	I nodded my head and let him take me by the paw to the bathroom, where he started running the hot water for a bath.  Then, to my surprise, he stripped down, revealing his own hard cubby cock.  He was only 8, but I was aghast - his cock was as big as mine.  He undid my diaper, letting it fall to the floor and reveal the boner beneath it.  My maw was drooling as he took my paw and we both went into the bath.
	"Big brother's going to show you something fun, okay, little bro?" he said, sitting me down as the warm water covered my nethers.  He stayed standing up and began stroking his dick in my face.  I had to stop myself from lapping at it as he began to pant.  Did he already know about masturbating?  I got my answer only a few moments later when he shoved his penis forward against my muzzle and tiny bits of cum started to come forth - bits that he then wiped on my maw.  I only whimpered, my own cock struggling as I was painted with his semen.  
	As his pants subsided, his paws found his way to my growing need, "Like this," he said, taking my paw in his and placing it on my shaft.  Slowly, he guided my paws up and down on my package, grunting as I began to buck into the water impotently.  The pawing sped up and in his efforts he inadvertently began rubbing his cock against my muzzle, forcing more of his dribbling semen onto me.  That little bit was enough to push me over and I shot my load into the warm water, dissipating almost immediately into the filled tub.  "When you get to be a big boy, stuff comes out, but you're still just a little baby, so the only thing that comes out is pee into your diapers," he teased as he continued to coax more and more out of me until I completely finished bucking into his paw.
	"I hope you liked that," he asked, embracing me in an almost apologetic way.
	I began to stroke his hair and licked him square on the front of the muzzle, "I loved it.  You can be my big brother any time."
