The fighting was over. Salem was laid to rest, Ozma was freed from his own curse, and Oscar was finally himself again. The gods deemed Earth, the remnant of a world, redeemed as humanity was united as one. That wasn't to say it was a sweet victory. There were still repercussions for everything done.
Ruby was in a coma, Atlas was now an underwater tomb, and Beacon Academy was completely destroyed. Then there's a group of former subordinates of Salem. Neopolitan begrudgingly joined forces against Salem and Cinder after the latter betrayed her back at the central portal location, and Mercury joined the redeemed Emerald in Vacuo. However, all three antiheroes were not getting out of the war without additional atonement for their crimes. The multicolored mute was sentenced to life in prison for her past record with Cinder and Roman Torchwick, while the trained assassin was given fifteen years, and the green haired thief had a ten year sentence.
They all went to the same prison in Vale, and Emerald found prison to be rather expected. She knew that she would still have to pay for her crimes when she decided to betray Salem after overhearing Oscar's discussion with Hazel. It was inevitable that she would have to do the time when the fighting was done. She was relieved that she wasn't going to be executed as she had feared.
The prison at Vale was interesting, to say the least. Emerald discovered that some prisoners shared cells, as she and Mercury were indeed behind the same bars. She also found out that, unlike Neo, they didn't disable her semblance for her sentence, but she refrained from trying to use it to escape justice. She had sworn to never again use her illusions for the wrong reasons, after what she had done during her time with Cinder. But the strangest thing to her was that there weren't separate showers for male and female convicts. They were all unisex, and she initially thought that was a bad idea, given an experience that changed her relationship with Mercury completely.
One day, they were both in the showers, when it happened. Every inmate knows not to drop the soap. It's not an official rule in prisons, but the dropper is vulnerable while trying to pick it up as other inmates may take advantage and sexually violate them. Emerald was using a bar of soap, when all of a sudden, it slipped from her grip and landed on the floor with a wet thump. She went pale as she saw the wicked grins of everyone else who turned towards her. But before any stranger would lay a hand on her, Mercury stood in front of her.
"I dropped it," he lied, before picking up the soap bar to do just that. "Go ahead. Do. Your. Worst."
"If you insist, bad boy," smirked a woman. It was a spider Faunus with short blue hair, matching blue eyes, and grayish vein-like marks running around her body that go to her gray hands, where her spinnerets were at. She was transferred to Vale recently from the prison in Menagerie. "I hope you're not afraid of webs…" and she went to work, wrapping up Mercury in webbing like prey in a real spider's web.
Mercury just stood there and took it, but Emerald could see he was blushing in embarrassment with tears in his eyes. Her eyes went wide as the woman began to wrap silk around the shaft of his cock, which was instinctively hardening from the Faunus' rather unexpectedly gentle touch. She stopped just at the base of the sensitive tip before moving to bind his legs, all the while licking his partly webbed cock.
"Nnnngh," groaned Mercury. He was actually enjoying it, but he kept up the tough face to keep the woman from seeing so. Unfortunately for him, the woman could tell he liked it. Emerald could see that the other inmates were blushing while they went back to showering during this situation. When the woman was done with his legs, she stopped her attack on Mercury's dick.
"Now this is where the fun begins," she said, preparing to slam her pussy on his cock, but Emerald had other plans, as she found inner strength and shoved the woman aside.
"I'm not letting YOU be the one who takes his first time!" she snapped, glancing at Mercury, who softly smiled and accepted her choice with a nod. Emerald nodded back with her own nervous smile, and positioned herself before aligning her unknowingly aroused vagina with his stimulated phallus. She held her breath, and began to take it in.
"Ooooooohh!" She yelped as she felt her pussy willingly get penetrated by Mercury's big, thick cock, who moaned in pleasure from Emerald's tightness. They were no longer virgins now. "Mercury, your cock feels so good…"
"I can say the same for you, Emmy," Mercury replied, panting as he began to thrust. Emerald seemed to like it and thrusted back, the two soon getting into rhythm. Suddenly, Emerald felt a certain pair of hands touch her breasts and begin covering them in silk.
"So be it," the woman said with a sinister smile, "I'll let you two indulge in each other in a tight cocoon. Oh, and the name's Trifa, by the way." Trifa then placed Emerald's hands on Mercury's ass and kept them there with webs, doing the same thing with Mercury's hands on Emerald's ass before wrapping even more webs around the horny couple, binding them together. Pretty soon, Mercury and Emerald were pressed up against each other in a nearly tight cocoon of Trifa's silk, stuck having sex while their bodies were wrapped up to their necks.
"Oooooohhh so tight! So soft! So kinky!" Emerald cried, marveling at the soft, cozy feeling of the silk on her bare body and Mercury's. They began to thrust faster, moaning in ecstasy of their new "prison."
"Emmy, I'm… I'm gonna cum!" Mercury gasped, fit to burst.
"Please, do it!" Emerald begged. "I'm close too! Give me that cock's looooaad!" She then screamed as her climax hit at the same time as Mercury's, the gray haired killer cumming hard inside her. They both continued howling until their flare died down and proceeded to passionately kiss in their locked embrace, moaning in each other's tongues and mouths.
"W-Well, as hot as that display was," stammered Trifa, who had fingered herself watching them, "it's probably time I get you two out of there so you can wash up properly." And she effortlessly went to peeling off all the silk, careful not to hurt the inmates trapped inside.
Later that night, Emerald and Mercury were in their cell. After the incident at the showers, they were too embarrassed and a little shy to talk to each other. That was, until Mercury spoke up.
"Why'd you stick up for me?"
Emerald smiled at her partner. "Because you practically saved me from a nasty gang bang. You didn't have to do that."
"No, but I didn't want you to feel any trauma from the other prisoners. Just as how I didn't want Tyrian to terrorize you, back when we worked for Salem."
"I really appreciate that, Mercury. I really do. Thank you, and I stepped in because I wanted to repay the favor. You seemed to be in my shoes when Trifa was having her way with you."
Mercury smiled fondly at Emerald. "We may not have grown up with people who loved us, Emerald, but as bad as our lives have been, you are the best part of mine." He then walked over to Emerald and caressed her cheek. "I love you."
Emerald smiled, tears rolling down her eyes and Mercury wiped them aside. "I love you too, Mercury…"
They had bunk beds, but tonight, they both went to sleep in the bottom bunk, giving each other a kiss.
"Goodnight, Mercury."
"Goodnight, Emmy."
Author's Note: Surprised? This time I wanted to see how an M rated story would go. It's clearly not related to my previous story because Ruby is still alive in this one, albeit not focused on. I didn't think I'd include Trifa in this one, but as I progressed the story, I went with her and her spider abilities, turning it from the initial idea of Emerald hiding herself and Mercury in the showers with illusions to have sex to Trifa putting them in a kinky cocoon. Neo was mentioned, but I think I'll cover more on her next time.
