And here's the big sequel I was talking about in Sideswipe's Sparkling Adventure. I'm actually glad that you guys enjoyed that story, it's my first time of writing any cute and fluffy story. But in all honesty, I suck at writing romance.

I'm into said genre because I care less about boys but more on my brain. Once I'm in college only THEN I'll start blowing some love spells. Until then, let the boys linger around my side. I do have a few as friends and yes, lately they've been somewhat...affectionate. But I got too many homework to notice. Sorry guys! :P

Read and enjoy. This is gonna be a mess.

"All I ever did is save people's lives, cure whatever disease they get and THIS is how You repay me? Damn fucking fragging slag who twists the damn crappin' shit like his own stupid piece of bitch!"

Optimus had to cover Sunstreaker's audios from Ratchet's cursing/grumbling. Now he finally knew what his CMO is like if he's officially pissed off. Sideswipe seems to be looking at the medic with a huge grin and wide optics, apparently learning some new curse words and memorising every single thing.

"I think that's enough corruption for Sunstreaker's mind, don't you think Ratchet?" Optimus' voice cuts the medic's rant. Ratchet's helm turn towards his leader that gives him the impression of a hungry lion.

"Prime, I think his mind is already corrupted ever since he's born to this world," answered the medic hotly. Optimus nods his head slowly, a soft huff could be heard from his vocals.

"Still, I don't think it's necessary to corrupt him with more,"

"Prime, we're here to discuss how he managed to turn into this, not about fritzing his processor with obscenities that he had heard and said throughout his lifetime,"

Optimus seems to think about it for a second. "Point. Sideswipe, how did you say you saw him turn into a youngling?" ask the Prime to the snickering frontliner. Sideswipe turns his head to the leader, grin still on face.

"Hm? Oh, I didn't really see him turn into a youngling, I just woke up from recharge and I couldn't find Sunny anywhere. Thought he'd gone for his shift but I felt him in the washracks. When I walk in, he's already like...this,"

Sunstreaker huffed and crossed his arms, not exactly happy with the turn of events.

"Watchet...pwease tell me you can fix dis!" whine the yellow mechling in a squeaky voice. Sideswipe covered his mouth in attempt to hide his mirth but Sunstreaker gave him an adorably pouty-pout glare.

"It not funny!" screech the youngling.

"Is so, you should hear yourself Sunny. You make Starscream to shame with that shrill voice of yours," snickered the red twin. Sunstreaker narrowed his optics and let loose a string of obscenities in sparkling speech. Ratchet stared at the screeching yellow bot and lazily turn his attention to Optimus.

"What did I tell ya? Corrupted before time,"

Prime groaned.

"So dear brother of mine, where should we go? Oooh...let's get Prowl! I haven't prank him in MONTHS! Got this thingamajig I snatched from Wheeljack that I've been dying to try out!"

Sunstreaker huffed, ignoring his brother's prank rant. All that the yellow twin wants is an explanation on how he managed to turn into a youngling and something to turn him back. If he's not back in mech form soon, someone's gonna die!

"Siiideesss..." whine the youngling. Sideswipe perk up from his rant to look at his brother who's currently on his arms. Since Sunstreaker's legs are too short to keep up with the mechs, Sideswipe had agreed to carry him around.

"Huh? What is it?"

"I'm hungry..! Get energon?" chirp the youngling happily. His face lit up with a bright smile that Sideswipe rarely see often, not after Iacon had been destroyed and they joined the Autobots. The smile seems to put Sideswipe in a daze, he continues to walk, yes, but his mind is focussed on his brother's smile...until he collided painfully into the wall.

"Sides moron.." mumble the youngling. His brother had kept a firm grip so that Sunstreaker would stay out of the painful collision and saved himself the time to bitch about his paintjob.

"Yea yea..I'm a moron and couldn't keep my attention for more than five minutes while you're the smart-aft who thinks he's superior.." mumbled the red twin as he rubs his dented nasal with his free hand.

"Not an aft!" chirp the youngling angrily whilst banging his little fists at Sideswipe's helm. Not strong, but very uncomfortable. "Sides aft! Moron!"

"Ow, hey! Careful, my helmhorns are sensitive! Geez..I should ask Ratchet to disable that vocals of yours, they're so shrill!"

Sunstreaker wailed and start banging his grinning brother as hard as he could, but later on his energy depletes and he slump back on Sideswipe's shoulder completely out of breath. Sideswipe smiles and gently pats his brother's helm upon reaching the rec room.

"I'm gonna get us some energon, you stay here and don't run off," Sideswipe said in a sing-song voice whilst poking his brother's nasal playfully like how a nanny would. Sunstreaker whimpered and bats his brother's hand away with a pout.

"Hey Sides, glad to see ya back to normal," Smokescreen's voice was heard over the energon counter. Sideswipe perk his head up and grins at the diversionary strategist. "The betting pool's kinda small without you in it,"

"Heh, I bet it is. Have you forgotten who's the best gambler here?" Sideswipe boasted, placing a hand on his hip. Smokescreen snorted at the tone and went over to the frontliner's side.

"You're only lucky on most occasions. Why do you think we're partners?"

Sideswipe eyed his friend but he didn't say anything, except the trademark grin that's still on his face. "Yea well, I have to take care of my brother. Apparently Primus is still having fun with us," he jerk his thumb to the direction of the couch where Sunstreaker is sitting. Smokescreen's jaw drop to the floor.

"That's Sunstreaker? You're joking! NO WAY!"

"Oh yeah..like I said, Primus is still torturing us. I better give him this before he decide to screech again. Guy's worse than Screamer on a bad day,"

Smokescreen's jaws open and close like a goldfish out of water. Sideswipe pats the blue shoulders and went over to the couch where his brother is waiting for his ration.

"Hey Sunny! I got your-.. Sunny?" The frontliner is curious where his brother had gone to. A few moments ago he was on the couch but apparently not anymore.

"Sidey! Sidey! Sunny want those!" a squeaky voice suddenly came out of nowhere. Sideswipe place the two cubes on a table and went over to find where his brother may be hiding. When he walk over the dispenser, he nearly have a spark attack upon seeing his sibling holding an overdue high-grade.

The liquid bubbles around in its cube and the dark pink colour is almost purplish. The cube suddenly slip out of the youngling's hand and fell straight for the black and yellow helm, if it wasn't for Sideswipe shielding his brother on time, Sunstreaker would loose his vision permanently along with corrosion on his thin armour.

"Oh...ow.. What were you thinking Sunny? Those energon are poisoned and could kill you! I brought new and safe ones right there on the table!" Sideswipe grumble out. Sunstreaker blink up at him and screamed angrily.

"SIDEY MEANIE! MEANIE MEANIE MEANIE! Sunny want energon! Sidey not give Sunny!" the youngling's scream turn into crying in just a few short seconds that made a couple of bots cover their audios from the high decibel. Sideswipe had to cover his brother's mouth just to shut him.

"I have energon, see? It's got a picture of Optimus on the cube!" Sideswipe tried his best to calm the little mechling. He stumble over his own pedes to get to the table, a wailing Sunstreaker in between his arms like a bookfile.

"See? Nice, warm energon just for my bro," he laugh weakly, shaking the cube about. Sunstreaker quiet down and the red mech place his brother on the couch where Sunstreaker grabs the cube and drink it eagerly.

"Alright, since Ratchet said not to do any work for today, we can have fun. What do you wanna do?" ask the red mech hopefully. Usually younglings are fun to play with, but Sunstreaker's just a mech in a youngling's body. Maybe he doesn't want to play but Sideswipe kept hoping he would.

"M'sleepy..." slurr the youngling. Sideswipe's grin now replaced with a pout because of that but he complied, no way is he allowing Sunstreaker to cry next to his audios.

The red mech bounce his brother slightly in his arms, keeping the yellow youngling awake for the moment. "You're no fun. Why do you want to sleep anyway? It's the middle of the day!"

The whining went unheard for Sunstreaker as he's too sleepy to think anymore. Just then, Ratchet and Wheeljack walk into the rec room to find the twins. The two motioned Sideswipe to follow them.

"Shouldn't I put him in our room first?" ask the frontliner whilst holding his brother close. Both medic and engineer shook their head.

"Bring him along. I need to do a thorough scan on him to find out what had happened. If it's got anything to do with the aging process when we tried to change you, then Wheeljack can change the affects faster this time,"

"Though I can't promise anything. I still need to run over the diagnosis and it might take days, weeks or maybe even months," explained the engineer as he rub the back of his head.

"Knowing Sunny, he'd want to be in his real body pronto," Sideswipe points out. The yellow mechling twittered in his sleep and snuggle into his brother's chestplates more. The sensation from Sunstreaker's earfin tickled his frame and made Sideswipe bit his lip just to not giggle and wake his brother.

Ignoring the weird look from both older mech, they made their way to the medbay.

888

"I'm not sure what's wrong with him because my scans showed nothing abnormal," Ratchet points out. He'd taken multiple scans until Sunstreaker woke up from his naptime with an angry wail. Sideswipe had to throw him in the air gently and tickle his frame to make him calm.

"Without a full diagnosis, I can't re-construct the machine. I'm not taking any chances on playing with another bot's life. We nearly lost Sideswipe once, we're not going to loose Sunstreaker this time," Wheeljack huffed. The frontliner watch the duo back and forth, clearly not getting where they're at.

"Umm...can someone explain what had happened until I nearly died?"

"You nearly die on many occasions. Like there's one time while we're in battle, at a beach and when we wanted to change you back to your mech form. Decepticons tried to kill you on both said occasions but you can thank your maternal-programmed brother here for your rescue. He's the one babysitting you through those time,"

Sideswipe glance over to the sleeping youngling and back at the medic who simply nods. The frontliner couldn't believe it, he knew how protective Sunstreaker is but activating his maternal programming? That was something.

"So now I owe him? And the payment is I have to take care of him like what he did for me?" Sideswipe carefully state out. Ratchet shrugs a shoulder but a grin slowly crept up his face.

"Look at it this way, at least he's older and won't be too troublesome to take care of. When you were a sparkling, even I had trouble babysitting you,"

Wheeljack's earfins glowed brighter and he was staring at his friend in disbelief. Even Sideswipe is having a hard time taking that as a truth. Ratchet does NOT have trouble when it comes to his comrades, they practically bow down at his feet when in the medbay. Save a few of course..

"You had trouble with him? Wow.." Wheeljack whistled out. The CMO merely whap him upside the head earning just a hearty chuckle from the engineer. Sideswipe is completely at loss for words since Sunstreaker didn't have enough time to tell him the whole story. But last night's cuddle was nice, very nice.

"And you're looking dreamy because..?"

Ratchet's words cut his haze short and Sideswipe is back in the present. His brother is still on the berth and ignoring each of them by idly swaying his legs back and forth to see how fast they could go. Looking up at the two older mechs, Sideswipe can only blink confusedly.

"Oh.. Sunny didn't tell me the whole story on what happened. But I have to say, after you chased us out last night, he gave me one of the more reason why I'm lucky to have him as a brother, albeit his slightly evil nature and psychothic nature. I've never felt him hug me in quite a while,"

Ratchet and Wheeljack listened patiently, then look over to where the youngling is still rocking his legs by the berth's edge. Apparently Sunstreaker's nurture had put the red bot in a deep state, and they don't know whether it's good or bad.

"Take your brother out for now. I've done with the scans now I have to worry about him not blowing himself up," Ratchet grumpily shove the frontliner and his brother out of the door as Wheeljack bid goodbye for the both of them. Sideswipe could clearly see the machine's blueprints in the engineer's hand just before the door completely shuts.

"Sunny hate sitting like dis," mumble the youngling unhappily. He carefully made his way on to his brother's back and stand up on the mech's ahoulder. Making himself comfortable, the youngling finally sits down with his hands holding Sideswipe's helmhorns tightly so he wouldn't fall to the ground.

"Comfy yet?" snort the frontliner with a smile. Sunstreaker twittered and they both head over to a certain SIC's office. Sideswipe had told Prime not to tell anyone because he want to make the surprise on his own.

888

Prowl is sorting out datapads, as usual, Jazz had given his energon ration without knocking, as usual, Sideswipe is smirking at his door with a youngling on his shoulders...that's way off.

"Let me guess, something happened to Sunstreaker after you had been converted to your age resulting into what he is now, am I correct?" state the black and white calmly. His answer is another large grin.

"Wow, quick and sharp. That's out logical and smart second-in-command. I guess we took you for granted most of the time," grin the frontliner, not at all fazed by the sharp look of said SIC.

You have no idea... Prowl thought bitterly. "Spare me the flattery and just tell me what is it that you require, I'm very busy at the moment," adds the tactician stonily. Sunstreaker who's been poking his brother's horns doesn't seem to mind the world but it's Sideswipe that Prowl's a bit...twitchy.

"I just want to know, now that I'm a full mech again maybe I can get to my shift? But then again, who's gonna watch him?"

A doorwing twitched slightly. He's not going to watch another mechling, running the Ark is bad enough without adding more trouble with it. Prowl cycle in a deep breath as he composes himself. Wings tilted high above his shoulders and back straightening.

"I don't think I would volunteer. You see, after you changed form months ago, the other bots are struggling to cover both of yours and Sunstreaker's shifts and the result are badly written reports. If this keeps up, we'll be completely out of sync in case the next battle comes up. So I suggest you go to your shift while I try and arrange some sitters for your brother,"

Sideswipe couldn't believe it! Prowl actually wanted to help him in babysitting Sunstreaker, without his puppydog optics no less! How the universe finally look at his way.

"Thanks Prowl! Even after all those pranks I did years ago, you're still willing to help me! Now I know we took you for granted. No wonder Jazz likes to hang out with ya, when can I get back on shift?"

"Tomorrow, DON'T be late," Prowl narrowed his optics at the reminder. Sideswipe grins and left the office happily not knowing that the SIC is gripping his table leg so hard that the metal bends slightly. His memory chip ran over some of Sideswipe's pranks that made him squeeze the leg tighter leaving dents along with it.

888

"Sidey..Sunny bored.." whines the youngling as he swing both his legs and hitting his brother's shoulder plates in the process. The red mech is clearly not happy that he's a ride for the yellow mechling. But hey..a brother is still a brother.

"What do you want to do anyway? It's only three o'clock and that heat! I just can't go outside, it might melt me into a puddle of metal," answer Sideswipe as he gaze out the Ark's entrance.

The sun is blazing in the clear sky, the air is hot and dry, the ground are beginning to crack slightly and not a single bird is out flying or chirping on the branches. Sideswipe's cooling systems activates just by looking at the scenery.

"Pway wit water, it nice an' cool," chirp the youngling matter-of-factly. Sideswipe leer at him the best he can but his brother just ignore the look like he's immune to it.

"Yea..and then the others would think that I'm turning into you. I don't think so Sunny,"

The youngling pouts and demands to be put down. Sideswipe carefully holds him and gently lower the mechling. Once he's on the floor, Sunstreaker dash off outside in a split second as his brother is left to eat his dust, literally.

"SUNNY! Where are you going?" shriek the frontliner upon seeing his twin brother already a few meters ahead of him. Without having a second thought, Sideswipe sprinted off to get him back.

"Sunny bored! Wanna find something!" shouts the youngling happily. The little ball of energy just seem to bounce off Sideswipe's grasp and sprint off to a tree, or a bush or anything he could find in a dessert. Sideswipe's core temperature is already increasing because of the heat and his movements are slowing down until he has to stop completely to cool his circuits.

After a few moment, the youngling is nowhere to be found. Sideswipe walk over to every tree and every bush he could find but his brother is still hidden from view, and it's starting to make him feel worried.

"Sunny! Sunny! Can you hear me?" shouts the frontliner. He may not have the maternal programming but he still couldn't help but feel worried over his brother. All his life, Sunstreaker always treats him not as an equal, but as someone younger. Sure he loves his brother's company but at times, he wanted to feel 'older' and see how it feels.

He got his wish, and it sucks!

"Sidey..." a voice calls out. Sideswipe whips his head around to find where the source is. After searching for a moment, he finally sees his brother under a shady tree and looking quite tired.

"Told ya not to run off," snort the red Lamborghini. Sunstreaker pouts and stick his glossa out whilst huffing in annoyance. He clearly shows that he's tired but pretending not to. Sideswipe knew it immediately and gently scoop his yellow brother up and placing him on his shoulders.

"Don't try to be tough, I know you're no longer bored. You're exhausted but you won't show it," grins the frontliner cheerfully. "Let's get inside, I think my tyres are melting,"

888

Later that night as others are already retreating to their quarters, Sideswipe is still drinking some mild high grade before turning off for the night with Sunstreaker already asleep on his helm. The others who are still awake to watch some late night movies are looking at him with curious optics.

"How the world works in mysterious ways.." Leanna sound off. She and Jeazmyne are staying up for a horror show with Jazz, Bluestreak, Beachcomber and Hound. The mechs are snickering at him and the sleeping mechling happily dozing off without a care in the world.

"I wonder how things are gonna work out this time," Jeazmyne pipes up. Her powerful camera are ready to snap some pictures for future use. Sideswipe finishes his cube and Jeazmyne starts to click her camera furiously.

"If I were you, I wouldn't pose so much, she IS a pro if you had forgotten," Hound reminds the frontliner with a smile. Sideswipe replies with a grin of his own.

"Of course I remember! I just want Sunny to see these pictures once he's back to normal and sound off his opinions on them,"

"Pay up if you want 'em, I'm not giving these off for free," Jeazmyne snaps back. Sideswipe seems impressed with her trading payment. He croush down to take a look at her.

"You and I are gonna be some of the beast dealers Cybertron and Earth has to offer kid. But fine, whatever," he then stood up to his full height. "I better put the tyke to bed, wouldn't want him to screech our audios off,"

With a wave, he went out of the room towards their shared quarters. Sideswipe punches in the code and step in, adjusting the light to be very dim.

"Well Sunny, I'm gonna cuddle you 'till you can't breath!" he whispers giddily. The youngling said something in his sleep and turn away from Sideswipe. "You're sleeping with me tonight,"

Sideswipe pile up the pillows and blankets so both of them could get comfy before placing his brother gently and climbing up. He twist around to get a pillow and his brother between all those blankets before finally setting in for the night

I hope this is as good as the previous story because I really am getting busier with work this year. Had to squeeze everything in so I could post it fast. Got 10 subjects I have to study just to pass a simple freakin' exam so I wouldn't change class and loose the science stream.

DAMN YOU EXAM!

That's all I got for now, reviews are welcomed and ideas will be accepted. Anything to make Sideswipe's (or Sunny's babysitters) life a misery is OK by me.
