A request from biffiea, I hope you enjoy it. ^^

A Pikachu comes over to babysit his younger cousin Pichu, though what he doesn't expect is that the little Pokemon has devious plans in mind...

I hope you all enjoy, I would love to hear what you think! ^.^


A pair of Raichus put on fancy clothing as their son, a pichu, sat in the front room pouting. He called in an annoyed voice, "Do I have to be babysat?! I'm old enough to look after myself!"

The couple sighed and looked at one another, the father rolled his eyes and walked into the front room and glared at his son. The whole scenario wouldn't be half as odd if not for one fact, the Pichu was bigger than normal. He had a lot of flab on his body making him look a lot bigger than normal, and he wore a diaper even though he had outgrown them long ago. "Son, you know you don't act your age. So we really can't let you stay home alone until you grow out of this phase."

The Pichu glared at his dad for a moment before giving up oddly quickly for him, "Alright, fine." His dad was thrown off, Pichu generally would never give in, so this was a nice change of pace.

Finishing up his tie, the Raichu smiled at his son. "Thank you, it's about time you act responsibly for once."

Pichu didn't say anything though as he picked up a poffin up scarfed it down, Raichu was put off but shrugged it away as there was a knock on the front door. The mother called out to the pair, "Pikachu is here!"

Raichu smiled at his son, "Alright, you heard that. Your mother and I are off for the night, we should be back by the time you're in bed." Pichu didn't say anything still though, instead he seemed to be deep in thought about something.

Raichu started to ask but shrugged, it wasn't his business to pry into his son's. He walked towards the door and opened it to reveal a happy looking Pikachu, "Hi uncle Raichu!" He said cheerfully, his ears flicking in joy.

The Raichu grinned back, his nephew had always been a nice and tidy boy, so whenever he needed a babysitter he decided to invite the Pikachu. "Good evening." He said back, the pair then turned and briefly touched their tails to one another in affection.

His wife then walked out smiling as her tail bobbed behind her, "Come on honey, remember we have a reservation."

He nodded back at her before looking at his nephew, "Pichu is pretty calm tonight so you won't have to worry about any trouble. We left some money on the counter just in case you get peckish, thanks again for doing this."

Grinning widely, Pikachu wagged his tail. "It's no problem uncle, as much as you two don't trust Pichu. I really don't mind looking after him."

The couple smiled and said their farewells as Pikachu closed the door behind him and meandered into the front room to find Pichu looking at him with a devious grin. Slightly unnerved by the odd smile, Pikachu chuckled lightly. "Hey cousin, how are you doing?"

Pichu answered by letting out a slimy fart, his diapers becoming soggy with brown logs. Pikachu coughed a few times as he smelled the foul odor, "Blech, that's nasty..." The Pikachu fanned the air in front of his face, he walked across the room and fiddled with the window there.

As the Pikachu messed with the window, attempting to open it. Pichu giggled as he hopped up and as fast as his pudgy little legs would let him, he ran over to his cousin and turned around before touching his tail to his cousin's ass. An odd green jolt transferred into the Pikachu, but he didn't notice as he finally slid the window up.

Finally letting the room clear of the odors, he turned around to find his little cousin playing with some toys on the ground. Pikachu smiled as he passed by his cousin, patting the Pichu on the head. "Having fun there little cousin?"

Pichu smirked, his tail twitching in amusement. "More than you can imagine Pikachu..."

But the Pikachu didn't pick up on the meaning hidden behind his little cousin's words and slumped onto the couch, coughing a little as he realized that the fart that his cousin had let out earlier was still wafting there. Pichu on the other hand took in a nice deep breath of the stench, taking pleasure in the odor. Pikachu picked up a book off of the couch and started to read it, humming as he did.

Pichu looked back to see his cousin flicking through pages, happily consuming his time with the boring task. The childlike Pokémon flicked his ears in irritation and let out a loud whine, "Iiii'mmmm hungry..."

Looking down, Pikachu blinked and rubbed his own stomach, feeling an odd hunger pain that wasn't there before himself. "Yeah... I guess I am two, why don't we go into the kitchen and grab a snack?"

The Pichu grinned and nodded, picking himself up letting his flab wobble around. Pikachu frowned as he looked at his chubby relative, he had always hated how fat his cousin looked but it didn't appear that he could do anything about it. The mouse pulled himself off of the couch and happily walked to the kitchen with his younger cousin in tow, as he looked for a healthy snack his cousin suddenly let out another whine. "I want poffins!"

Pikachu sighed and smiled halfheartedly at his younger cousin, "I'm sorry Pichu, but you know that your mom and dad don't like you having junk food all the time."

But the Pichu wouldn't be easily swayed, he stomped his foot and pointed at the box of poffins on the counter. "I... want... POFFINS!"

Pikachu gasped in surprise as he felt something odd travel though his body, not noticing green sparks flying off of his body at random. He himself suddenly had cravings for poffins, "Oh... you know what, I guess a few poffins won't hurt."

A evil grin appeared on the Pichu's face, "Yeah..." Pikachu then grabbed the poffins and walked into the living room with them. He sat the poffins in a spot where the both of them could reach it and laid back on the couch, picking up his book once more as he chewed mindlessly on poffins.

Watching his cousin carefully, Pichu ate poffin after poffin watching as Pikachu himself also ate them, though less in quantity. As he ate poffins, the older pokemon didn't notice that his body had started to shift. When he had walked into the house, he had been a nice slender build for a Pikachu, but after the shock to his ass from Pichu, he had started to put on pounds.

As the older mouse ate the poffins his body had started to puff out, not like a little bulge from his stomach. It was as if he were being blown up like a balloon, his form very slim at first started to enlarge. His smooth gut started to grow out into a nice pot belly, wiggling slightly as Pikachu continued to eat poffins.

Pichu watched as his cousin's figure changed, the pillows under the Pikachu started to sink in as the figure above them grew in size. Pikachu's ass had been very smooth, but now it had grown out into a more bubbly butt, a slight stench of musk escaping from the cheeks.

Pikachu's arms flabbed out a bit, along with his face. Giving him a more childlike face, though still recognizable as a Pikachu's face.

After thirty minutes, the pair had eaten the whole jar of poffins, but even so Pichu was still hungry. "Pikachu!"

The chubby Pikachu, unaware that he was still gaining pounds flicked his ears in curiosity, "Yeah Pichu?"

The smaller mouse pointed to his stomach, "I want more food!"

Pikachu frowned, "Pichu, we just ate all of those poffins. We really shouldn't be having anything else."

But Pichu's eyes glinted with a sinister glare as he shouted at his cousin, "I! Want! McPokes!"

Pikachu's body arched for a second as more green electricity passed over his body, a second later hunger burned in his eyes too. "You know what, your parents left money on the counter. Let's go get some food from Mcpokes."

Pichu giggled in childish glee, "Yeah!"

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

At Mcpokes, a Wigglytuff hummed to himself as he cooked up some Pokeburgers. The store had been quiet for a good hour, save for the odd visitor, until the door ringed causing him to turn. "Welcome to Mcpo... Pikachu?"

Wigglytuff had turned to see his friend Pikachu with his cousin Pichu, the odd thing wasn't that he was with his cousin, the odd thing was that the electric type had not only put on quite a few pounds, but he had seemed to of become shorter. Pikachu grinned, "Hey Wiggly, haven't seen you around for a while."

The pink pokemon stammered a bit, "P... Pikachu, since when did you put on those... pounds?"

Pikachu looked down and saw the flab, and he himself started to panic but a moment later something clicked in his head and all was normal. He smiled as he looked up at his other friend, "What are you talking about Wiggly? This is how I've always been, now we're here to order."

Wigglytuff started to argue but his boss, an aggressive looking Clefairy passed by at that moment and he was forced to take the order. "What can I get for you two?"

Pikachu started to order a light meal, but Pichu shouted out his order. "I'll take three poke burgers, two large fries, and a large soda!"

The order at first sounded absurd to both Pikachu and Wigglytuff, but a moment later the order sounded absolutely delicious to Pikachu. "I'll take that too."

Wigglytuff looked at Pikachu in shock, "P... Pikachu, that's a lot of food. I really don't think that's healthy for the two of you."

Pikachu was usually very calm and collected, but something was changing about him. No longer did he just want to be polite, he wanted things to go his way. His face turned angry and he slammed his chubby arm on the counter, "I said that's what I want, so give it to me now!"

Wigglytuff was shocked by the Pikachu's outbreak and started to stammer, but as he tried to reply his boss rushed to the counter angrily. "Wigglytuff, what are you doing?! Give these two their food right now!"

Ducking his head in shame, Wigglytuff ran back to the stove and started to cook up food. Clefairy quickly bowed in apology, "I'm so sorry mister Pikachu, please forgive him."

Pikachu's face was still annoyed though, "if this is how we're treated here, I want the price to be reduced!"

Doing anything to keep the customer happy, the Clefairy sighed and accepted quickly ringing up the food at a lowered price. A few minutes later, the chubby cousins walked out of the resturaunt happily. Wigglytuff tried to stay out of the view of his boss but a moment later heard his name called out, "Wigglytuff, I think it's about time that you open your application back up..."

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Pichu couldn't believe how well his plan was going, after learning from a shady Abra about the spark from his tail. He had been waiting for the perfect chance to try it out, and it was working perfectly. His cousin had started out as the usual stick in the mud good guy, but now he was becoming like him.

As the pair scarfed down food, Pikachu had shrunk down to his cousin's size. Only a few things let them be able to be distinguished from one another. Pikachu let out a loud burp causing them both to giggle, Pichu let out an equally loud burp causing them to giggle once more.

They both lounged back as they finished eating, food stains greasing up their bodies but they didn't care. All was silent until Pikachu felt an odd urge, "W... what the?"

A crazy urge to pee erupted through the chubby Pikachu and he blushed as he jumped up, "So... sorry Pichu, I'll be right back..." Pichu watched in amusement as his cousin rushed into the bathroom and quickly used it. After a minute, the Pikachu walked out sighing in relief and plopping down once more. As he did so, he smelt urine in the air. "What the...?"

He followed the scent until he realized it was coming from his cousin, "Pichu, did you pee in your diaper?"

Pichu giggled, "Yup."

Pikachu started to tell the other Pokemon how wrong that was, but once more the horrible urge to piss once more arose and he rushed back into the bathroom. Pichu's face grew devious as he snuck over to a box in the corner of the room and pulled out a new bag of adult diapers, urinating in his diaper as he did so. The Pichu had let all control of his urination go a while back and loved to wallow in his soggy diapers and smell the pure stench of them.

As Pikachu came back into the room once more he sighed heavily as he flopped onto the floor once more, making the house shake a little with his girth. Pichu pulled out a diaper and wandered over to his cousin who had his eyes closed, quickly the younger Pokemon slipped the diaper over his older cousin's crotch watching as a confused look appear on Pikachu's face until he saw the diaper. "Pichu, what in the world is that?!"

Pichu giggled, "It's your diaper silly." Pikachu frowned and started to tell his cousin that he didn't wear diapers, but as Pichu pissed once more into his soft diapers the green sparks ran over Pikachu causing his eyes to widen in surprise as he used his diaper for the first time and fell in love with it.

A grin grew on Pikachu's face as he felt the urine run down his crotch and through his ass crack, "Ah... much better, thanks Pichu. I can't believe I forgot my diaper today."

Pichu giggled as he patted his cousin's diapered ass, "It's ok cousin, I was just wondering if you wanted to play toys with me?"

Pikachu started to say no, but his last resistance broke and a childlike grin appeared on his chubby face and he nodded excitedly. "Sure!"

As the pair sat down to play with the toys, Pichu glanced at the book sitting on the couch and decided to test one more thing, "Hey cousin, don't you want to read your book anymore?"

But Pikachu looked at the book with disgust, "Why would I read a boring book when I play with toys?"

Pichu giggled, "Okay." The pair then played with their toys, no longer hindered by any adult rules.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The Raichu giggled perversely as they came close to home, "Well, that was one heck of a night, huh honey?" The father said with a grin on his face. The mother nodded and the pair smiled as they approached home. "How much do you think we should give Pikachu today honey?" He asked his wife.

She thought about it, "Well seeing as we stayed up a bit later than usual, I think thirty Pokes should do it." Raichu smiled and nodded as he opened the door for them to both be hit by a wave of musk and gas. They both gagged as the smell escaped from the entrance, "What in the hell?!"

The couple both gagged and looked into the gas with horror, "What in the world happened in there?!" Mister Raichu asked in horror, the misses didn't know and only shook her head. The couple slowly walked into the house and looked around until they saw who they assumed to be Pichu, "P... Pichu, what happened in here?"

But the mouse only giggled as he bounced in his diapers, "I'm not Pichu uncle it's me, Pikachu." They both froze in terror; Pikachu flicked his ears in happiness as a log of brown suddenly went into his diaper. The Pikachu's height had diminished to the size of his cousin, his stomach looked as if he had been eating all day. His face was extremely chubby and his arms had also become very flabby, they noticed a brown bulge in the back of his new diaper. They tried to ask what happened, but the Pikachu pulled a poffin out of his diaper and looked at it happily. "Oh look, I found another one." And he stuffed it into his mouth without another thought, causing both Raichu to become rapidly sick.

"I have to head home now though, g'night guys." He kissed his aunt and uncle on the cheeks and giggled as he pissed his diapers again. The pair both nearly gagged once more as they realized what he had eaten just a moment before.

As the Pikachu walked out of the house, the couple followed him out watching as his chubby ass waved in his diaper. Tucked under the mouse's arm was a bag of new adult diapers. Misses Raichu looked at her husband in horror, "Do... do you think Pichu had something to do with this?"

Mister Raichu nodded slowly, "I think so..." The pair then walked into the house to find it full of fumes, as misses Raichu went one way mister Raichu walked into the front room. "Son...?" As he glanced around, he didn't notice a green spark touch his ass.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Miss Raichu left the house the next day, her husband saying that he didn't like girls as if he were a kid again. Raichu grinned as he sat in his big diaper, his tail flicking happily. The big mouse no longer had a nice physique that he used to have, he had grown nice and plump and had shrunk quite a bit. A fart escaped from his ass as Pichu smiled up at him, "Thanks for the new toys daddy."

The father giggled childlike as he pushed a toy lapras around, "You're welcome. Your cousin Pikachu is coming over today to play with us!"

Pichu cheered as they both soiled their diaper, a moment later a knock on the door sounded as if to signify that the fun was about to start.
