The next chamber the heroes entered was decorated with mirrors from top to bottom. Based on which generals were left, Christy could already narrow it down to two deadly sins, but decided to wait until she was certain.
Not taking any chances this time, the group already assumed battle-ready positions before approaching the next general. Continuing the theme of this room, the general wore an armor that was decorated with mirrors and other reflective materials. “Greetings, heroes, I am Inviridia, general of envy,” the general introduced himself.
That was Christy's cue. She took out the TF gun while Inviridia was monologuing and with careful aim not to accidentally hit one of his mirrors she shot the demon general. Inviridia’s body gained a metallic sheen all over before suddenly losing definition and collapsing into a puddle on the floor. The puddle quickly reformed into a human shape. A busty female hourglass shape with a long dick, to be exact. That was pretty much all, the body not having any further details with its metallic skin instead perfectly reflecting what happened around her.
“And it looks like it’ll fall to me to take care of the heroes and this traitor,” Inviridia said from a mouth that formed on the head of the figure. The rest of her speech must've gotten lost during the transformation, but Christy doubted it was important. “Let's see if you're able to handle yourselves!”
Suddenly Inviridia turned back into a puddle only for it to massively increase in size, obviously intending to cover the whole floor in her metallic slime. Most of the heroes quickly reacted out of instinct. Jamie, Bryce and Christy flew straight up with their wings, while Toby scaled a nearby pillar with her claws. A scream got Christy’s attention. Oh shoot, in their hurry they had forgotten not all of them were this mobile.
Leah’s wheelchair had already been surrounded by the metallic goo and several slimy tendrils were starting to latch onto her. Without thinking Christy dove down and grabbed Leah’s arms in an attempt to pull the mermaid to safety. Unfortunately the tendrils proved deceptively strong and Leah barely moved an inch. Still, Christy held on to her.
Another scream made the former general look to the side to see Nico in a similar predicament as Leah. Unable to fly or climb the deertaur had attempted to outrun the villain’s slime attack. Sadly the room was only this big. Jamie and Bryce were already approaching the hero of earth, only for her to suddenly shout out to stay away from her.
Christy was confused for a moment, only for a slimy feeling up her arms to answer her questions. In the short time it took to look over Inviridia’s slime had almost completely covered Leah and already had progressed to her. Unable to let go now she could only continue her pointless struggling as the slime quickly claimed her as well.
Soon her head was covered, leaving Christy with only one sense, touch. And it was quite something she felt. Unable to move herself, all of her body, especially her erogenous zones, were being massaged from all sides. At the same time slime tentacles filled all of her holes. But try as she might, she couldn't reach an orgasm. The slime and tentacles were masterfully keeping her on edge. It was wonderful bliss and horrible torture at the same time. This went on for several minutes to the point that Christy was certain she'd go mad soon.
That's when she suddenly felt her body being touched by something else. Another body was caressing hers in all the right places. Something big and scaly was rubbing against her legs. And a long shaft entered her front pussy. Christy immediately recognized the shape of the key to her lock simply through feeling. It was a dolphin penis and that meant Leah was in here with her. The slime’s prisoner opened her mouth to accept the mermaid’s tongue and let herself be carried to the sweet release of orgasm. Cum and other juices shot out of all of her many sex organs (and the two Leah had) and quickly filled the tight slime bubble they were in to its limit until it burst.
The former general turned to the hero of water. “Thanks, but how did you–”
“I can't call myself a mermaid if I wasn't able to swim through any fluid, though I couldn't escape on my own. I have to thank you, too. If you didn’t try to save me, we two wouldn't have ended up in the same bubble.”
Christy took a deep breath of air. She laid with Leah in her arms in a puddle of Inviridia’s slime, though it seemed that mixing with too much cum made it docile. The room had been mostly cleared by the slime wave with only harmless bits and pieces sticking in a few places, including the three heroes that evaded capture.
Later Christy learned that shortly after her, Leah and Nico got trapped in big slime cocoons the wave had receded on its own. Instead slime clones shaped like the three prisoners spawned out of the cocoons and took on the three remaining heroes with copies of their respective techniques. Thankfully they weren't as strong as the originals and soon were reverted back to puddles just before Christy and Leah freed themselves.
With the numbers now in their favor the heroes resolved to finish this up quickly. Christy, Jamie, Toby and Leah went to rescue Nico with the latter jumping straight into the slime and the other three (four, if you count Madison who was technically doing the most work) helping by jamming their cocks into it and cumming as much as they could. It didn't take long to pop the bubble.
Meanwhile Bryce took on Inviridia, who had reformed her main body. Before the general of envy could come up with any other tricks the metallic angel had already closed the distance and rammed her rod through her featureless head. At the literal mindfuck the metallic slimegirl gave a loud cry of orgasm and defeat (more the former than the latter) and dissolved into a bubbling puddle that shouldn't bother them again any time soon. She didn't even get to curse at them and talk about how much stronger the upcoming generals are.
The heroes took a moment to clean themselves from any slimy remains and praise Christy for another selfless action by her. The heroes seemed to have already accepted her as one of their own. Before long it was time to approach the next chamber and whatever threat was waiting for them in there.
