A/N: This is another from me. Don't even ASK where this pairing came from. It came from the depths of my twisted mind. XD Anyways, yeah. Enjoy, peoples! Oh, and blood shifter, don't get your knickers in a knot. I got your request on the way.

Wheeljack/Perceptor (G1)

"Fantastic"

"There." Wheeljack announced to himself. "That should do it." He had just put the finishing touches on a new invention of his, the Shock Ray. It was similar to the humans' stun gun, but much more powerful and with a few variations. "Let's test this baby out." The engineer flicked the switch, and--

BLAM

"Shoulda seen that coming." He groaned, crestfallen as he rested his head on a nearby wall and allowed his arms to hang limply. He sighed, then lifted his head from the wall only to bring it back down with a THUD. If only he was smart like Perceptor. The red mech's inventions and experiments never ended with an explosion.

As if on cue, the microscope transformer walked through the open door, knocking on the wall. "Are you alright, Wheeljack?" He asked, genuinely concerned. "Are you damaged?" He continued, walking closer to the white and green mech.

"Nah, I'm fine." Wheeljack responded, standing straight to face Perceptor, revealing to the red mech, his charred chest and face plates. "Just a bit...disappointed." He admitted, averting his gaze to one side. "My inventions either blow up in my face before I get to use them, or the Decepticons get a hold of them, and they blow up in my face anyways."

"I believe what you require, Wheeljack, is a primary engineering assistant." The red mech stated. Wheeljack looked at him blankly and Perceptor gave a slight chuckle. "I would like to help you." He stepped towards the remnants of the Shock Ray, which lay smoking on top of Wheeljack's worktable. "If I may?" The engineer nodded hesitantly and the scientist picked up the burnt remains, examining them closely. "Ah. See here?" He motioned to a small flame inside the invention. "Now, I don't have much engineering knowledge, but I believe that is not meant to be combustible." He took out some sort of vacuum and sucked up a small sample of smoke from Wheeljack's failed project.

Wheeljack smiled behind his faceplate; at every motion Perceptor made, a new innuendo popped into the inventor's mind. He gasped as an unexpected pressure was put on his codpiece. The more he looked at the scientist in microscope mode on the table, the more the pressure grew. He groaned; this wasn't fair. Why'd he have to be attracted to a mech he couldn't have?

Perceptor heard the small noise that Wheeljack made and transformed, looking at the charred mech worriedly. "Are you certain you are not damaged? Perhaps I should run a diagnostic." The red mech offered.

"No, no. That won't be necessary." The white mech declined.

Suddenly, Perceptor's beautiful face scrunched into a slight frown. "Alright, I believe we both know that I didn't come here to make sure you were still functioning from that explosion." Wheeljack was taken aback, and let it show. "I was relocating to your quarters when your invention detonated." He paused thoughtfully. "Wheeljack, there is something we need to discuss." The white mech raised an optic ridge curiously, and Perceptor continued, matter-of-factly. "It has come to my attention that word of your attraction to me has made a trip around the base and back." The engineer's face grew noticeably red. Perceptor smiled. "I have a confession to make."

'Oh, Primus, please let this be what I've been waiting for!'

"I find myself attracted to you in turn." Perceptor finished, much to Wheeljack's triumph as the inventor removed his faceplate.

"Thank you, Primus..." The white mech muttered, loud enough for his counterpart to hear. "Perceptor," He directed his speech at the red mech. "I am dyin' to get a taste of you. Ever since I first saw you, I've wanted to know how you taste, how you feel." Wheeljack took this opportunity to step closer to the scientist, boldly kissing Perceptor's cheek, while gently stroking the opposite side of the mech's face. The engineer put his lips right at the scientist's audio sensor. "You taste great."

Perceptor could hardly stand it anymore. He grabbed the other mech by his shoulders and yanked his chassis as close to his own as was possible, then he pulled Wheeljack's head closer, locking their lips together in a surprise, passionate kiss.

Wheeljack jolted; this, he hadn't been expecting from the timid, withdrawn scientist. 'There's more than meets the eye with this one!' He thought, mentally grinning. Slowly, Wheeljack's hand trailed down Perceptor's beautiful red chest, past his midsection, stopping at his codpiece. He looked up into the scientist's optics. Perceptor smiled, though Wheeljack could tell that he was nervous.

"Permission granted." Came the shaky response from the red mech.

Wheeljack's hand continued on its course, snapping off Perceptor's codpiece and letting it clatter to the floor as the scientist's cock sprang out of its prison, quickly rising to salute the one who'd freed it. The white mech didn't hesitate to grab onto it, shuddering at the feel of the thick, warm organ in his hand. His other hand moved to take off his own codpiece, releasing his own rock hard cock which Perceptor grabbed onto, immediately beginning to jerk him off. Wheeljack let out a low moan; Perceptor really knew what he was doing. The fact that the scientist was much more experienced than Wheeljack expected him to be, left the engineer motionless with awe.

He grinned and Perceptor gave him a curious look. Wheeljack didn't give a response, only moved to his knees in front of the red mech, slowly moving his hand up and down Perceptor's pole.

The scientist didn't protest, like Wheeljack thought he would. In fact, he did the exact opposite; he encouraged him, by laying a gentle hand on the side of the white mech's face, moaning in anticipation.

With a tedious lack of speed, the engineer slid the scientist's thick cock into his mouth. Wheeljack deep-throated Perceptor, then pulled back slightly, running his tongue all around the hard shaft. The scientist shuddered and groaned. So it was true. Mechs did give better blow jobs; they knew all the sensitive spots.

As Wheeljack's head bobbed up and down on Perceptor's mech-hood, the latter felt his release beginning to build up inside him. He felt that he should be doing something for the engineer, but Wheeljack had a grip on his own rod and was pumping in sync with his thrusts on Perceptor's.

"Ohh...uhng.." Perceptor moaned and grunted, squeezing his optics shut tight. "Ahhohhng...Wheeljack!" He cried out as he took his release inside the other mech's mouth. Most of his cum spilled out of the inventor's mouth, but what didn't was swallowed.

Perceptor dropped to his knees and lay down on the floor. Wheeljack lay beside him.

"I take that back, Perceptor." The white and green mech said. "You don't taste great." He paused for effect. "You taste fantastic."

Sorry, guys. I was hoping to get that up a lot sooner, but my bf passed along "The Sickness"...I have had a five-day weekend. :(
