Transformers (G1), Galvatron/Rodimus Prime, heal
It's Hot Rod instead of Rodimus, but eh, same diff. Set post-S3, follows this exchange.
*****
He'd always been a cuddler, but this time there was a desperate intensity to Hot Rod tonight as he clung to his lover, still shuddering with the aftereffects of their lovemaking. Galvatron made an impatient noise and shoved at him, and Hot Rod let go almost immediately, tucking his arms in and curling up like something wounded.
Galvatron shoved at him again, rocking the smaller mech back. "Are you still dwelling on him?" he demanded. "You'll hurt my tender feelings if you keep on with that."
Galvatron didn't clarify who 'him' was; he didn't need to. "Sorry," Hot Rod rasped, struggling upright. He clasped his arms over his knees and put his head down, hiding his bright optics from Galvatron. That wouldn't do at all, Galvatron thought, but his instincts told him that roughness was not what was called for here. Instead he sat up, slipped an arm over Hot Rod's shoulders and pulled him flush against his own chest. Hot Rod relaxed almost immediately, fitting his body to Galvatron's. "You'd think I'd forget after a few rounds with you," the Autobot muttered into Galvatron's sigil, chuckling weakly at himself.
"What ails you?" Galvatron persisted.
"The attack on Autobot City."
Though Galvatron himself had attacked Autobot City many times, he didn't have to ask which attack his young Prime meant. Megatron's last battle with Optimus Prime - the beginning of all of his pain. "Hot Rod," Galvatron said, forcing himself to patience with his foolish, fragile Autobot, "Optimus Prime sent you to me to cheer you up. Surely that means he's forgiven you!"
"Optimus Prime forgives too easily," Hot Rod growled, tensing up again.
"Of course he does," Galvatron snapped, hands tightening on Hot Rod's arms and heedless of the groan of stress under his grip. "He is an Autobot. A sentimental, weak creature clinging to the past. Just like you, my Chosen." Hot Rod gasped and struggled, and the last of Galvatron's tenuous self-control snapped. He threw Hot Rod to the berth and pinned him there with his own weight, reveling in black delight as his victim struggled in vain - Rodimus Prime could have thrown him off, but Hot Rod was helpless.
"Shall I tell you what happened that day from my memories?" he said heartlessly, as Hot Rod's fingers scratched his chest. "Because I do remember. I can tell you every detail."
