Sweet oblivion lasted less than a few minutes before the slime around the imprisoned Supermare bubbled and recoiled in shock by a pair of red beams blasting into it. The slime pony head looked enraged as it turned to see a pair of red eyes still at the entrance of the cavern, standing on solid dirt. It had been so focused on its super prey that it had retracted itself from most of the solid cave floor just to keep Supermare prisoner.

“Let mah sister go!”

The voice was full of youth, eyes still bright, red as the mane of the pony that spoke. Stepping into the light of cave, the slime creature saw a yellow filly with the same symbol on her chest as the prey it had worked so hard to overpower.

Apple Bloom was glaring daggers at the monster, sparing only a second to see her sister encased in a blue-glowing pod. Applejack’s back was facing Apple Bloom, hiding how her stomach was bulging full of magic-draining cum.

Tendrils shot out from the base of the slime, racing to capture the smaller pony. They wiggled and twisted in the air, trying to make it hard for the new superpony to use its heat vision to hurt it.

Instead of using heat, Apple Bloom had sucked in a great breath of air, and blew with enough force to not only push the slime tendrils back, but also freeze them in place. The frozen tendrils cracked, falling and shattering on the cave floor as the slime recoiled from as it had from the heat vision.

Floating off the ground, Apple Bloom appeared in a costume similar to her sister’s but fitting her a bit more skimpily. Her stomach was left bare as the white top of the costume hugged her upper chest. A blue skirt covered her blank flanks as her cape reached a few inches past the hem of her skirt. She still looked like a young filly, but her face was all business as she didn’t wait for the slime to attack her again. She blew another gust of frost breath on the slime, spreading ice all along it. The slime broke off from its frozen parts, dropping the pod that imprisoned Supermare as it tried to pull away from the arctic breath.

Unlike heat vision, there was no way for the slime to avoid this kind of attack. Apple Bloom kept up her offense, taking great gasps of air, freezing more and more chunks of the slime solid. The slime head looked distressed as more of it was frozen. The nucleus pulled away from the shape of the head it had made, swimming away just as Apple Bloom’s frost breath froze the head into a solid block of ice.

More than half the cave floor had frozen before the slime started to retreat. It pulled away deeper into the cave, as far from the chilling breath as it could manage. Apple Bloom flew after it, watching as the slime sank into a crack in the cave floor. She was a second too late to freeze the rest of the slime creature, but didn’t hold back as she froze the cave floor, sealing the crack in a thick layer of ice.

Apple Bloom was left gasping after that. She felt a little dizzy after having taken so many deep breaths so quickly. She floated over the cave floor, seeing how most of it was frozen solid now except for the area around Applejack. Great chunks of slime laying broken on the floor, reflecting the light of cave ceiling in a thousand different angles. It would have been pretty if Apple Bloom had stopped to admire it.

She flew right for the glowing pod, now able to see how Applejack was clutching a very large stomach. The sight of it was so wrong that she couldn’t believe what she was seeing at first, but the shock was quickly replaced with anger.

“Ah should have come sooner. Hold on, ah’m gonna git you outta there right now, sis. You’ll be okay as soon as-”

Apple Bloom was cut short as something pulled hard on her mane. There was a crack in the cave floor not too far from her where the slime she thought she had chased away came flowing back up. As it pulled on her mane from one side, a part of it flowed in front of her, leaping off the ground. Apple Bloom’s initial reaction was to shut her eyes look away, just as the slime had hoped she’d do. It struck her in the face, keeping her eyes shut and her mouth sealed as it began to flow past her flips and inflate to keep Apple Bloom from biting down or blowing out anymore of her frost breath. Her gloved hooves tried to wipe the goo away, but instead they stuck to her face worse than any tree sap Apple Bloom had ever gotten on her.

Muffled protests came from behind the purple slime as Apple Bloom fell to her side, desperately trying to pull the slime off her. The nucleus was over her face, willing the rest of it’s body pool around the dangerous filly. Her cape and back became stuck to the floor as more slime flowed up her hind legs, traveling under her skirt. Apple Bloom couldn’t breathe, couldn’t kick the slime off her as it kept pulling on her mane. As it started to tickle over her haunches, she manged to force her eyes open a little, just enough to barely make out the nucleus controlling the slime.

It was all she needed. Apple Bloom’s eyes lit up, and there was no escaping the blast of heat vision that engulfed the small brain of the slime, disintegrating it.

The slime on her not only stopped moving, it lost its consistency. The purple goo thinned out to the consistency of water. Apple Bloom spat out what had been gagging her, coughing as she gasped for air.

She shivered, still able to remember what the slime felt like when it had gotten under her skirt and… touched her. She spat more, wiping her mouth.

Whoa nelly… that was too close…

It took a short time for Apple Bloom to recover. When she did, she made sure there was nothing underground waiting to attack her from behind. Thankfully, she found no trace of the slime.

Fearful that the slime in the pod that kept her sister trapped was also alive, she kept her distance as her heat vision cut through the jelly structure of the pod. It popped like a water balloon, spilling out Supermare out on the floor. The fluids she had been in never showed signs of being animated.

Apple Bloom rushed to Applejack in an instant.

“Sis? Sis! Please wake up. It’s okay now, ah beat that slime thing, burned it right up. Please, open your eyes sis!”

Applejack didn’t respond, but her stomach did.

The slime jizz instead her stirred, no longer sensing the link to the brain that controlled it. It lost it’s shape and its ability to feed on Applejack’s powers. If Applejack hadn’t already been soaking wet, Apple Bloom would have noticed how her the crotch of her sister’s costume was leaking surprising amounts of fluids.

The sun! Ah got to git her out in the sun!

“I don’t think there are words that could do justice for how thankful we are to you.”

Apple Bloom blushed, making an effort to not smiling too big. Her sister stood next to her, smiling a little as she gave a nod to Twilight Sparkle.

After recovering from her encounter with the slime creature, Applejack wasted no time going back to Ponyville, finding Twilight, and getting her to call in the royal guard. Within hours, the heart of the Everfree Forest was busy with gold-clad knights securing the many pods in the cave. Twilight estimated that it would take all day and the day after to recover everypony inside it.

“I’m only sorry that I didn’t find them sooner.” Supermare spoke in a sober tone. Apple Bloom and Twilight both thought that the mare of steel sounded different, but neither wanted to touch on what the experience with the slime had cost her.

“Judging by the number of ponies, I’d estimate that this… slime monster, was keeping ponies prisoner for a couple of years; longer than you’ve been around.”

Applejack looked away from Twilight to the cave entrance, watching the guards guide unconscious ponies on stretchers. “What about your friend? Rainbow Dash?” Supermare asked. It took more effort than normal to not let on that just why Supermare would care so much about Rainbow Dash, as if they were best friends. Apple Bloom noticed, and looked hopefully to Twilight for good news.

“Well…” Twilight started, wondering how best to explain her findings so far, “Physically she’s okay. Unconscious still, but okay. The only thing I could see that was wrong with her was the severe depletion of her internal magic. She won’t be flying for a while, or walking on clouds for that matter. That seems to be the pattern with all these victims. Everypony has a little magic in them, but it looks like while they were in those pods, their magic was being absorbed. For what, I can’t say since the slime monster is gone. It’s not unlike how changelings will seal a pony in a pod and feed on its love. But I’ve never seen anything that attacks a ponies magic like this. I still can’t believe you were able to defeat it.”

Supermare shook her head, smiling a little more as she wrapped one of her front legs around Apple Bloom. “It wasn’t me that beat that thing.”

Apple Bloom blushed brighter, and Twilight looked surprised.

“Then you must be one extraordinary little filly.”

Apple Bloom’s smile beamed with pride, “I prefer Superfilly.”

Twilight chuckled, and offered a hoof to shake. Her smile was perfectly rehearsed for this moment. Great, now there’s two aliens, and I’ve got one less experiment…

Author's Note

I hope you all enjoyed this little trip into my favorite fetish. If you're thinking that this story is open-ended, that's because I'm going to revisit Applejack as Supermare in another story that might shed some light on what's going on with Twilight, and show if Applejack reveals her secret identity to Rainbow Dash like she wanted to.
