Title: For Science!
Rating: T for tentacle porn
Fandom: Transformers G1
Pairing: Rodimus/Perceptor
Summary: What do you do with a tentacle'd Autobot?

"Fascinating." Perceptor bent over Rodimus Prime's back with the scanner, seemingly heedless of the golden tentacles that twined and flexed around him. "They seem to be integrated with your sensory systems, Rodimus. It will be delicate work to extract them."

"I don't care what you have to do," Rodimus told him grumpily, his voiced muffled by his arms. "Just get them out of me."

"Yes, of course, Prime." Despite the formality of the words, Perceptor's hands were comforting and familiar as he patted Rodimus's shoulder, setting the tentacles a-wriggle. "I know you're uncomfortable. We'll have these parasites out of you in no time." Rodimus suppressed a smile at being talked to like one of Perceptor's wayward chips. "Though you know you wouldn't have blundered into that nest in the first place if you hadn't insisted on such flashy heroics as regards my safety."

"Flashy?" Rodimus protested. Perceptor laughed gently and patted him again, and Rodimus subsided with a halfhearted grumble. He lay still as Perceptor worked, but the tentacles that had sprouted (painfully) from his back and sides were not so obliging. The two thickest ones, rooted just above his hips, gripped the medical berth while the dozen thinner ones twined through the air and each other, exploring, probing, searching blindly. They obscured Perceptor's view of his scanner and poked his arm and twined thoughtlessly around his sensitive hands. Perceptor let out a strangled squeak. "Rodimus, do control your tentacles."

"They're not my tentacles!" Rodimus protested, and the appendages writhed in agitation at his voice. Perceptor sighed and attempted to unwind the clingy alien life forms from around his hands.

"Just so," the scientist admitted. "The parasites don't seem to be hooked into your fuel tank. Curious. I wonder where they get their energy."

Rodimus sighed and propped his chin in his hands, trying to stay still. The tentacles were wiggling quite enough for him. Some of them had already oriented on Perceptor, and as the scientist squirmed in vain, more of them left off their random writhing to wrap around him.

"Rodimus..." Perceptor said in a shaky singsong. "They're..."

Rodimus was no less affected, rocking back and forth on the berth. "I can't - I can't control them," he gasped. "You'd better get out of here -"

"No, no - they're not hurting me, just-!" Perceptor's voice cut off with a squeak and a giggle as one of the tentacles nudged his jaw. "That tickles!"

Rodimus raised himself up on his elbows and turned, staring at Perceptor incredulously. Thus he got a perfect view of Perceptor's face when one of the tentacles found its way into his hip joint. "Ooh!" he gasped, clutching at the coils wrapped around his hands, and Rodimus squirmed so hard he nearly fell off the berth.

"Primus," the young Prime muttered, clutching the berth's edge. "I can feel you - I feel what they're feeling -"

Perceptor's optics lit and focused. "You receive sensory input from them, as well as sending..." He trailed off as a tentacle wound down his leg. "How very fascinating. From a purely academic perspective, of course," he added with a sly smile.

"Yeah, sure-" Rodimus bucked, a cry bursting from his mouth that merged with the cry Perceptor made at the tentacles squirming in his hip joints. Cursing, Rodimus rolled to one side and gripped the amorous appendages, pulling them back with all of his strength.

"What are you-" Perceptor whined, suddenly bereft.

"I can't control them," Rodimus grunted, hauling them back hand over hand. "But - maybe - I can tame them - No! You touch where I let you!"

Perceptor startled, blinking, before he realized that Rodimus was talking to the tentacles, not to him. The Prime knelt in a writhing knot of the things, gripping hard enough to leave dents, showing no sign as to how much it must have hurt. Awed, Perceptor knelt on the end of the berth, but didn't dare to approach any closer than that.

"Perceptor." Rodimus whispered the name. "Do you mind... being my test subject?"

Awe and arousal made the decision easy. "I am yours to command."

Rodimus held out an arm, a single tentacle coiled around it. Perceptor held still, entirely unafraid, as the tentacle stretched out, sought out his scope, and coiled around it as if embracing a lover. The tip nudged sensor-wires along a seam and Perceptor moaned.

More tentacles emerged, one by one, as Rodimus allowed them. By his direction, they wrapped around Perceptor's forearms, nuzzled his chest and torso, slid along his mouth. Curious, Perceptor kissed the tip of that last one and watched with interest as Rodimus shivered and purred. "Does it feel similar to my kissing you?" he asked.

Rodimus shook his head. "Y-yes and no - sensors all fire at once - like an all-over kiss..." He shifted closer and the tentacles tightened around Perceptor's body. "Do it again?"

Perceptor gladly kissed that tentacle again, watching rivetedly as Rodimus crooned and writhed. Kisses became licks, licks led to allowing the whole head of the tentacle into his mouth. Rodimus cried out, head tossing back, and his tentacles slid free of his shaky control to wrap around Perceptor and squirm into sensitive areas. Overwhelmed, Perceptor toppled forward and fell into Rodimus's arms.

They kissed without thinking, mindless pleasure-seekers under the tentacles' influence. Rodimus's hands wandered up Perceptor's back and down again, eliciting a groan of approval from the scientist. Perceptor wound his hands around the nearest tentacles, gripping and squeezing restlessly. Rodimus cried out and tangled his legs around Perceptor's hips, proving that the friendly parasites had no monopoly on clinginess.

"I think," Perceptor gasped, his voice crinkling with static, "I think I've figured it out."

"What?" Rodimus struggled to lift his head from Perceptor's shoulder and listen. It wasn't easy with such overwhelming stimulation in every part of his body.

Perceptor flashed him a knowing smile, reading his lover's difficulty and sharing it. "They're not parasites. They're symbiotes," he answered, kneading a tentacle tip fondly. "Social and physical benefits to the host. I'll write up a full report when I'm not being driven mad."

Rodimus laughed. "And what do they get out of it?"

"Mobility," Perceptor answered, "I theorize. And-" A tentacle chose that moment to invade Perceptor's connection port, cutting him off mid-word. He cried out, head tossed back, and Rodimus took the invitation to nibble his throat cables.

"And?" he purred, licking over the vulnerable tubing.

Perceptor whimpered. "They feed on - systems energy - released during interface - oh Primus!" He clutched Rodimus close, engaging him in a desperate kiss. Rodimus returned it with joyful recklessness, rocked back to pull Perceptor on top of him, and a tentacle wiggled itself into both their mouths as if it couldn't bear to be left out. The sensory feedback from mouths to tentacles to bodies was enough to bring them both to overload.

"I lost control over them," Rodimus murmured, once he'd recovered enough to speak. "Pretty quickly, too."

Perceptor chuckled and gathered both Rodimus and his sluggishly-rippling tentacles close, petting the symbiotes fondly. "Discerning how to remove them safely will take time," he assured his leader. "We will have ample opportunity to work on your control."

Perceptor's engine quickened within him even as he spoke, and the tentacles stirred in response. Rodimus rebooted his optics, revved his engine and laughed.
