Pearl had been more hesitant than Amethyst to become an Amazon, but with her friends, and the entire fandom-verse, on the line, she eventually accepted it. Both of them knew who the next Succubus was, a fusion gem by the name of Garnet, the strongest of the Crystal Gems.
Stevonnie was surprised to hear that such a gem was not the Elite of this world, and was nervous to hear who would end up being the Elite, but she figured she would worry about that another time. Right now, she just needed to focus on the current Succubus.
Amethyst and Pearl waited until Garnet was alone in the temple, then moved in on her. Korra used her metalbending to block off the exits while Amethyst and Pearl fused into Opal, as handling Garnet by themselves was a near impossibility.
They already knew Garnet's kinks, all they needed to do was wear her down first. Opal would have the advantage, as she could get several shots off from her bow before Garnet could get close enough to attack, and could jump farther away than Garnet could to avoid her.
Korra waited and watched as the two fusions battled. She stayed on her toes, taking pop shots whenever she could to help Opal out, as even fighting with her bow against Garnet's close quarters gauntlets, Garnet was still tough.
Finally, after several minutes of battling, Stevonnie found an opening, and shot a massive blast of fire. Garnet withstood it no problem, her clothes not even singed, but she made the mistake of turning around to try and attack Korra. The moment she did, she was hit with a shatter shot arrow from Opal.
The shot cut off all of Garnet's clothing, exposing her luscious dark skinned body and knocking her to the ground. Her gauntlets flew off her hands, and before she could summon them again, Korra gripped the gems in her hands with her earthbending, preventing her from using her powers.
Garnet still struggled, rushing Opal and trying to fight her even without her weapons or gem strength. This was determination that Korra could admire, if not very well thought out, as Opal basically just backhanded her to the ground.
Opal held Garnet's wrists with two hands, and held her legs apart with the others. She allowed her clothes to vanish off of her body, showing her pale, slim but slightly curvy form. Garnet growled and squirmed, but the chances of her actually breaking loose were low, even if she had had her full strength.
Opal shapeshifted slightly, forming two massive members, one above her pussy, one below. Both were already stiff, thirteen inches long and nearly four inches thick. Korra was impressed by the sight as Opal lined up both to Garnet's pussy and ass at the same time, jerking her hips forward to push into both holes at once.
Garnet grit her teeth, refusing to make any sound at first as Opal's strength let her force her cocks deeper into both of Garnet's holes without any lubrication, letting her meet Garnet's two kinks of high intensity and fusion at the same time. Korra wouldn't have minded joining, but there wasn't anything she could do to help, and simply waited with a tent forming in her pants.
Opal bucked her hips harder, pushing both cocks deeper into Garnet. Soon, Garnet started to grunt and groan as she felt them push deeper and deeper into her, stretching her cunt and asshole out as inch after inch was forced inside mercilessly.
Garnet fought it with everything she had, but before too long, she started to moan as well, her own moans mixing with the sound of Opal's, who was more than enjoying this, a mix of Amethyst's love of sex and pleasure and Pearl's love of being in control and powerful. It was possible that they had never been more in sync than they were now, which was a little funny considering they were doing so to more or less rape their best friend, at least to Korra.
Soon Opal didn't even need to hold Garnet down, as she had entirely given in to the pleasure. Opal's hands went to Garnet's hips, pulling them towards her hard as she thrust forward, helping push her in harder until she was hilting herself inside of Garnet with every movement, and the sound of their hips slapping together was echoing throughout the temple.
Korra was having to summon all of her willpower to avoid touching herself as she watched Opal rail Garnet harder and harder. Opal and Garnet came at almost the same moment, crying out loudly as Opal pumped several large spurts of hot cum into Garnet's holes, filling her up before they both fell to the ground.
As they laid there, panting, Garnet's body began to glow, and she separated back into Ruby and Sapphire, who were both naked as well. They were still for a few seconds, then Ruby got on top of Sapphire and began kissing her hard, their bodies grinding together.
This was a problem, Korra realized. The Succubus energy had been leaving Garnet's body, but there was still some within Ruby and Sapphire. If they had just stayed still, the energy would have left them and everything would have been fine, but now that they were continuing to have sex, the energy was taking hold again.
Looking over, Korra saw that Opal was tired out from Garnet, and hadn't noticed anything wrong. Korra acted fast, removing her clothes and rushing over to the two smaller gems as they moaned and rubbed together. Korra lined up, thrusting her cock between the their pussies, making them both moan louder.
In their lustful haze, neither of them could be bothered with wondering who Korra was or why she was joining them, and both simply accepted that it was happening as they kept going, enjoying the feeling of Korra's member between them as Korra enjoyed both getting to help and getting to get off.
Real quick, before you head over to the next chapter, who do you think the SU Elite Succubus is going to be now that we know it isn't Garnet?
