It was late in the evening on board the Lost Light. Most mech's were tucked away in their berths, enjoying a hard earned recharge. All but Brainstorm; he was not most mech's. Not long ago, after the intrusion of the Legislators, the teal mech came up with a brilliant idea for a sort of home protection device. He spent vorns working on this project nonstop, and tonight was the night all his hard work was going to pay off. All the hard work was going to pay off with the flip of a button.

"Here we go," Brainstorm said to himself and flipped the switch on. The engine hummed; belts whirled to life, and the machine vibrated as it came to life. "Aha!" The scientist exclaimed with glee, but it was too soon. The machine let out a gargled noise and choked itself out.

"Scrap!" The mech yelled and immediately bent over the contraption. After flicking off the switch, he fiddled around with the engine and inspected for loose parts, wrong hookups or anything that looked faulty. "Everything looks right… what could be wrong?"

He tinkered around with the gadget, even took the top off the engine to double check the connection there. All appeared to be incorrect order. Letting out a sigh, Brainstorm was stumped. And he hated being stumped. He plopped himself down in a chair and rubbed his fingers over his optics as he wondered what to do now.

A voice nagged him in the back of his processor. 'Perceptor can help' the voice said, which brought a ping of excitement, as well as a sense of dread. It's not that he didn't like the other scientist; it was far from the truth. Brainstorm enjoyed Perceptor['s company very much so that he often wished their time spent together ended up in a berth.

"Stop thinking like that," Brainstorm told himself. Even so, the mech still wished Perceptor showed interest in him other than just friends. However, throughout the time they spent together, usually working on one of the winged scientists projects, the signs of interest were never observed, and Brainstorm just left it at that.

"Well, doing nothing won't get this pile of scrap working," Brainstorm said as he walked to his communication pod. "Minus well bite the bullet and ask him for help." He dialed Perceptor's code and listened to the buzzing as he waited for his fellow scientist to answer.

"Ug..What is it now, Brainstorm?" Perceptor groggily spoke and sat in front of the pod.

"Hey, how did you know it was me?" Brainstorm asked, taking note of how tired the other bot looked.

"Because only you would be calling in the middle of the night," Perceptor said with a lazy smile. "What do you need?"

"I need your help. This device I am working on isn't working right. Do you think you'd be able to look at it?" Brainstorm asked.

"Can't it wait until morning?" Perceptor spoke.

"Sorry, I didn't mean to disturb your beauty sleep Perc," Brainstorm joked. "You know me, I am not going to be able to sleep til I get it working."

"Yeah, and apparently, neither will I," Perceptor replied. "Give me a few, and I'll be right over."

"Thanks!" Brainstorm chirped, and Perceptor only gave him a glare before turning off the communication.

So, Perceptor was going to help him with his gadget, which means it will be working in no time. Brainstorm smiled to himself as he walked back over to his invention. He double checked the connections and worked on decluttering the area. No point in giving Perceptor something to tease him about.

A knock was heard on the door, and Brainstorm quickly shoved some junk behind a table before walking to his door. "Who is it?" Brainstorm asked out of habit.

"Who else is crazy enough to show up at your workshop in the middle of the night?" The voice answered.

Brainstorm palmed the keypad, and the door swooshed open. "Perceptor! Hey, thanks for coming." The teal and grey bot stepped aside and gestured for the other mech to enter. "I just need another set of optics to look over my device. I just don't understand why it's not working..." Brainstorm babbled on, but Perceptor just walked over to the machine and began looking it over. "…I checked the connections…" The red and black mech popped open the control panel and was checking out the readouts. "…It kinda worked, but made some weird noises and choked itself out…"

"Well, isn't that odd," Perceptor said while still fiddling around in the control panels.

"What? What is odd?" Brainstorm questioned as he walked behind Perceptor to see what he was looking at.

"The fact that one of your inventions made a weird noise, that's never happened before," Perceptor teased and cracked a smile. "I found the problem though, seems that you configured it wrong."

"No way," Brainstorm said as he stooped down to get a closer look. It was then that he noticed how close he was to Perceptor. He could see the other scientist was freshly waxed, as well as smell the polish. Quickly, Brainstorm stood back up, thankful that the red mech was busy tinkering with the control panel to notice that he was blushing.

"It's a good thing I am good with numbers, so I can recalibrate this for you," Perceptor idly stated as he entered different coordinates into the panel. "Perhaps if you weren't teetering on the edge of being a mad scientist, you wouldn't need my help all the time."

"Well, as a scientist, I want to have fun and not have to calculate all the time or worry about silly things that get in the way!" Brainstorm retorted, and instantly cringed. How silly that must have sounded.

"Hmm," Perceptor hummed and snapped the control panel shut. "Safety protocols are silly? You are starting to sound like Wheeljack."

"Hey! That was uncalled for!"

"Your invention should work now, Brainstorm." Perceptor said, and he stood back up and faced the other bot. "Now, if you'll excuse me, I have to get back to, what did you say? Ahh, yes, my beauty sleep."

"Wait! Don't you want to see what it does?" Brainstorm called out.

"I am sure I'll hear about it Brainstorm. Literally." Perceptor smiled to himself, knowing that would get under his plating.

"Come on," Brainstorm said and grabbed Perceptor's arm. "I want you to witness this. It'll be great!"

"Whatever," Perceptor said as he gave in and decided to see what the contraption did. Brainstorm had led them to stand right next to the machine, but as soon as the winged mech let go, Perceptor put some distance between the machine and himself.

"Ready?" Brainstorm asked and looked up and looked confused when Perceptor wasn't there. Looking around, Brainstorm spotted the other scientist more than halfway across the room. "Hey- whatchya doing all the way over there? Can you see from there?"

"I'm fine," Perceptor said and held up his hand to the other mech. "Go ahead, turn it on."

"Here we go!" Brainstorm happily said and flicked on the switch. "Watch the magic begin!"

The device roared to life, and the winged mech grinned wildy behind his face mask. The experiment would have been a huge success had it not started smoking. Before either of the mechs could do anything, loud booms along with flashing of lights filled the room. Charges of energy erupted from the gadget, shooting both mech's square in the chest, throwing them onto the floor. The last thing Brainstorm remembered was the room fading to black.

… … … .. ….. ….. … … … …

"HHmmmrgggh," Brainstorm grumbled as he optics flickered, opened and worked on focusing, "what happened?" He wiggled his body; he could feel everything just fine. Thankfully, he appeared to not be majorly harmed.

Percy?" Brainstorm called out weakly. He cleared his throat. "Perc, you ok?" No answer. He rolls his head to the side, but all he could see was his equipment scattered, his work table turned on its side, and his new experiment broken. "Scrap."

Without much consideration, Brainstorm slowly stood up. He was a bit wobbly at first, but steadied himself by placing a hand on a support beam. Something didn't feel right; the room looked slightly different, but he couldn't figure out why. He shook his helm and brought a servo to his optics and rubbed them. And that is when he realized something was different with his hand.

"What the…" Brainstorm exclaimed as he inspected the hand. He clenched a fist and relaxed a few times to make sure the servo worked. Perhaps it was just charred? "No, that can't be it…" Brainstorm whispered. The hand was of a different design, not just a charred version of his own.

He brought in his other arm and inspected the servo. Same result. It wasn't until he noticed the red forearm did he realize he was not in his body. Turning to go find Perceptor, Brainstorm stopped dead in his tracks as he saw Perceptor standing in front of him, wearing the same shocked expression.

"I…ah…" Brainstorm pondered. He waved at the image of Perceptor, and the image waved back. "No way…" As if not believing the first test, Brainstorm frantically waved both arms out in front of him. Once again, Perceptor did the same thing at the same exact time. "Uh oh." Brainstorm exclaimed, and for good measure, jumped, waved his arms and kicked his legs all funkily just to see Perceptor do the same thing. Yup, that was his mirror on the other side of the room, and what he was seeing was his reflection.

Brainstorm approached the mirror to further inspect the damage, but something caught him out of the corner of his optic. He was his body laying face down on the ground. "Perceptor!" Brainstorm called out and went over to check on the other mech. "This is so weird," Brainstorm muttered as he checked his body lying on the ground. All his vitals were fine, and there was no major damage done to the body. "Must be knocked out."

He stood back up, wondering what to do. Should he comm Ratchet? Brainstorm winced. He would get into a lot of trouble for pestering the CMO at this time of night. Not to mention, Ratchet would be furious that his invention damaged someone. "He should be alright. I mean, I am ok. No major harm done, just swapped bodies."

Letting out a sigh, Brainstorm rubs his weary optics and begins pacing. The machine was broken. He was in another bot's body. Perceptor lay unconsciously on the floor. What was he to do? As he walked, his reflection in the mirror caught his attention again, and he stood admiring his reflection. Brainstorm smiled at himself, enjoying how Perceptor looked. He bit his lip and gave a lewd smile; Primus did that make Perceptor look hot!

"Well, Brainstorm," He said as he quirked a brow. "You're looking mighty sweet today." His cheeks flush a tad as he looks over his body. "You are such an amazing scientist. Have I ever mention that? Not to mention, you are one sexy fragger."

With only a moments hesitation, Brainstorm ran his hands over Perceptor's frame. He started circling his hands over the broad chest, then slipped his hands lower to caress his abdominal plate. Primus, this felt so good! Between feeling the plating on his fingertips and what felt like energy pulses beneath his plating. Brainstorm felt the foreign body begin to heat up. Looking up in the mirror, he gave a coy smile.

"Heh, you like when I do that Perce, don't you." He spoke to himself. Seeing Perceptor with half-lidded optics and a look of pure joy was too much! And that's when he saw it; the forbidden object that Brainstorm always tried to touch, but Perceptor would always yell.

"Well, there's no stopping me now," Brainstorm mumbled to himself and crept a hand up to Perceptor's microscope lens. Like a sparkling interested in a shiny object, Brainstorm stood optics wide, and jaw dropped as he brought and servo up and rand a finger over the lens. Brainstorm couldn't help but laugh. However, upon running a finger around the circumference of the lens' edge, Brainstorm discovered why Perceptor didn't want any bot to touch it; because doing so felt so good it sent shivers through his body. Cooling fans clicked on, and Brainstorm felt the body react to his touches. Upon feeling the pressure build behind his interface panel, Brainstorm blushed. He was getting himself, or rather Perceptor aroused.

"Oh boy," Brainstorm muttered, feeling guilty about wanting to open the interface panel. He let out a sigh and looked at his body laying on the floor. No change in its condition. Well, it's not like he could focus on anything in this state, so he minus well release his building charge. Licking his lips, he rubbed a pair of black servo's down the body he was in, ticking at seams as he went. His vents hitched. Primus, Percy's body seemed to be super sensitive, or maybe it was just because Brainstorm was, in a way, touching Perceptor.

The interface panel felt hot as his fingertips grazed gently over it. Upon tracing it's seem, the panel retracted, and Brainstorm inhaled sharply when the cooler air touched the warm surface. The spike, which was pretty much pressurized, slid out, and Brainstorm stared at it in shock.

"Damn, Percy, who knew you were packin'?" Brainstorm said as he wrapped a hand around the black and red spike, which, was rather on the bigger side than he'd imagine. Slowly, he traced his hand from the base to the tip, enjoying the tingling sensation that flowed through his hips and up his back. The winged scientist took the time to trace the tip, then fondle down along the underside of the spike, messaging the bumps and nodes as he went. Primus, this would feel good in my valve! He picked up his pace a bit, pumping his hand in a steady rhythm as he worked himself up.

His optics shot open when he felt something trickle down his thigh. Curiosity won out, and Brainstorm swept his free hand at the sensation. When he brought his hand to his face, he discovered that what he felt was transfluid leaking from Percy's valve.

"Primus, Percy, you are full of surprises!" Brainstorm moaned and commanded the valve cover to open. More transfluid seeped out, and spreading his legs; Brainstorm rubbed his fingers over the exposed port. He continued to jerk himself off while the other hand traced the rim of the valve slowly before pressing inside. "Hmmm... Primus!" Brainstorm muttered.

"Excuse me," A voice interrupted, causing Brainstorm to jump. " It's not nice to play with such intimate parts without permission."
