Nowadays, it seems like you can't go onto the Transformers romance section without half of the fics being about non-con. I'm going against the bandwagon and actually giving femmes the power to decide what happens.

Main characters: Elita One, Optimus Prime, Megatron, Blackarachnia

EDIT: Forgot to say that this was originally posted June 26, 2009. Just now moving it over. .

Elita One.

The word tasted like sweet fire on his glossa as he murmured it to himself.

Her name invoked many images in the processors of those who heard it. She was not beautiful in the way that the dancers and dolls were. Elita One was in a category all of her own, a beauty forged from the intoxicating combination of her confidence and knowledge, of her power and her dangerous ways. Optimus had been ensnared by her sapphire optics, and was now completely helpless to fight the maelstrom of emotions that she evoked within his spark.

Like an organic creature from the planet Arachnia, she had spun a delicate, all-encompassing web of lies and deceit among his ranks. Pitting mech against mech in a futile attempt to gain her favor. Blackmailing the Councilors and his lesser Primes for materials and goods. Using her body and venomous charm to influence and sway the very mechs she had once blackmailed. But like dumb, hungered beasts, they followed after her in the hopes of tasting what she would give, to sate their appetites and quell their needs.

And Optimus only knew of her actions because he watched it all. He had been ensnared by her as well. He was on the fringe of her web, but he knew that he was next on her list. Her soft velvety words, whispered as the siren pouted up at him for his attention. Optimus knew he would give in eventually. She knew it, too. His spark shuddered. She was everything that his courtesans were not. Elita was as exquisite as the rare crystals that formed deep under the surface of Cybertron. She had endless wit and charm at her disposal, and she did not hesitate to employ her sweet, empty words on the mechs she extorted. She was as cold as the ice-moon that orbited their planet, rumored to be as spark-less as the Unmaker himself.

Optimus was enthralled by the Femme Commander and her conflicting personality. Elita One was a nominal Autobot, for she was loyal only to herself and her femmes. She would do whatever it took to ensure that she and her femmes outlived the males, even if it meant selling her abilities to bring life into the world.

Femmes were much smaller and weaker than their mech counterparts, and lacked the power and resources to build their own bases. A weak alliance had been forged between the leaders and the dominant femmes. In return for their services as medics, theoreticians, scientists, and sparkling-bearers, Optimus Prime and the Autobots would provide them with protection, shelter, energon, and medical equipment. It was a very unstable truce, for the Decepticon femmes were offered the same by Megatron. If one leader offered an extra thousand energon units for ten fliers, then the femmes would join him. The other would have to raise his bid. It was a vicious cycle that the femmes had ensnared the mechs in. Elita One often commented on the irony of the situation.

"Imagine that! The weaker and smaller of the species, twisting and coercing the most dominant! How amusing," she would say, laughing as she stroked the arm of the mech seated beside her, the one who had gained her favor this orn. They would all laugh along with her, but with cold, humorless optics. They knew the power she held over them.

The mech Commanders were not stupid. They both understood that they needed the femmes to continue the species, to provide more soldiers for them to command. Especially fliers. With what the femmes lacked in power and size, they more than made up for in their sheer ability to control their bodies. Forced or an attempt to force interface on a femme yielded very unpleasant results. Permanent damage to the cortex from powerful viruses was the least damage that the 'Cons and 'Bots had encountered. Blackarachnia had a love for draining amorous mechs with her bare fangs, and Elita One was quite fond of ripping spark chambers out. Their femmes followed the same paths. The mech Commanders had to tread very carefully with the femmes if they were to secure fliers and mechs from the femmes.

They could have gone to the AllSpark for replacements, but the AllSpark always created mechs. Mechs could not produce anything but other mechs. Their sparklings were usually weaker than ones produced by femmes. They rarely lived a vorn or two after their adult upgrades. Femmes could mate with mechs, other femmes, and even fliers. A femme-to-femme mating produced all three genders, which was something that both factions valued more than energon itself. Femmes were very precious to both Optimus and Megatron, and severe punishment was swiftly carried out if a femme was harmed. Blackarachnia was very fond of draining errant males with her fangs.

Blinking away the thoughts, Optimus continued gazing at the femme.

Elita One was the mirror of her femme-equal among the Decepticon ranks, as cunning and treacherous and wily. Rumors flew of how the femmes negotiated peace treaties when they squabbled with one another, and for the most part, they were entirely true. Both Femme Commanders understood the importance of their gender, and had pledged to do all that they could to keep one another alive through the war. After all, what would a femme want with a mech if she and her sisters were capable of continuing the species by themselves?

They had an ulterior motive. That was the only thing Optimus was certain of regarding the females.

Ice blue optics narrowed when the dusky-red femme made an appearance only a few dozen yards away. Optimus continued musing on the Femme Commanders. His spark shuddered both in pleasure and dismay as he realized just how similar Elita One and Blackarachnia were.

They ruled their femmes with complete authority, but unlike Megatron, who was often at odds with his Second in Command, Elita One and Blackarachnia had no need to swear punishment or to deal out beatings. The femmes in both factions followed their leader without hesitation or doubt. They were eager to please and serve.

Perhaps they were a little too eager.

Optimus and Megatron still hadn't figured out how Elita and Blackarachnia inspired such fierce loyalty from their femmes, though they had heard hushed tales of how the femmes rewarded loyalty and success. Of how femmes were given the pleasure to lay with their Commanders for the night. He had even heard rumors of how the Femme Commanders negotiated treaties with one another. They were wild, sordid tales of repeated interface to see which femme was dominant enough to start negotiating treaties.

His optic shutters closed slowly, and he thought for a moment. The mere thought of Elita One wrapped in a passionate embrace with Blackarachnia aroused him until his spark ached. Almost as though she sensed his intent, Elita looked up at him. She let a slow, knowing smirk spread on her faceplates. She glanced over at her platoon. They were too busy to notice their silent interaction. Elita motioned to the hallway, and Optimus acknowledged her with a slight nod.

Maybe it was time to finally give in.
