Rainbow Dash sat just inside the cave as she took several deep breaths as she prepared herself for what was coming. She felt excited about joining the night guard. Considering she was rejected by the Wonderbolts. But she also felt nervous about introducing her friend to her mate. She looked over at the alcove where he was hidden from view. She didn't want to have him wait too long and make him worry. But she also wanted to make sure that her friend won't get the wrong idea or jump to conclusions. Not that they all would be wrong or anything. But she wanted to be the one to tell her about him and what may have happened… or at least will happen at some point.

Taking a deep breath she turned as a flash announced the arrival of Luna and her friend. Taking a deep breath, she got up and turned to welcome them before looking in shock at who it was. "Twilight?!?!"

"Rainbow. You're ok!" Twilight cheered and leapt to give her a hug before getting caught by Luna in her magic.

"I see you are well Rainbow." Luna said softly as she set Twilight next to her. "Is he here?"

"Resting in the back, princess." Rainbow replied, giving them both a quick hug.

"Last I heard, you were severely injured." Twilight mentioned in concern. "I'd like to do a medical scan to see how well your healing is doing."

Rainbow Dash blinked in shock before gulping and stepping back. "I don't know about doing that right now Twilight." She quickly looked around before motioning to the pile of food. "Why don't we have something to eat?"

"Rainbow Dash. If I don't check your condition, you can end up with an infection, or a previously unknown fracture can get worse or-" Twilight countered before Luna cut her off with a hoof.

"Or we can trust she has a good reason she doesn't want to have you scan her. And we should wait till she's ready to tell us." Luna sighed.

Twilight sighed and looked at Rainbow in concern. "Ok. I'll wait till you're ready. But I hope when you are ready. You'll let me know."

"Well…" Rainbow started before a loud yawn came from the back of the cave. Sighing she gave them a soft smile as she slowly stepped backwards. "I'll be just a minute." She said before zipping to where the sound came from.

Twilight blinked in shock as she turned to see Luna smiling softly at the back of the cave. "Princess. I know you said that I shouldn't ask touchy questions. But I'm really concerned. The guards told me there was a lot of blood where she was attacked. And she was injured in flight, which means she can have multiple broken limbs."

"I understand your concerns." Luna replied. "But you will see soon why it is important for her to be the one to explain what is happening."

As if on cue, Rainbow came back out with a soft smile licking her lips. She was grateful that Twilight hadn't seen her, and even more so that Luna simply smiled at her knowingly. "So… you know about my friend that saved me and came to get the cider?..." She chuckled. "Well…"

Twilight's eyes widened in shock as the dog-like creature came out and stood next to Rainbow Dash. Upon seeing Luna, it gave a graceful bow before turning to Twilight in suspicion.

"Hi… I'm Twilight Sparkle. Rainbow Dash's friend. I'm grateful for your help taking care of her and keeping her safe." Twilight announced calmly. "I'll see what I can do to repay your kindness."

He huffed and pulled Rainbow close with a wing, causing Twilight to blink in shock and confusion. Rainbow gave a nervous chuckle. "Yeah… he's a bit more than my savior…"

"So you two are friends? That's great!" Twilight cheered.

"More than that." Rainbow laughed before licking his chin.

Twilight blinked and stumbled back in shock. After a moment to let it process she smiled. "I'm happy for you. But I do have a few questions." She glanced at Luna who nodded. She turned to face Rainbow and her lover. "I don't mean to pry… but… have you two… you know…"

"Yes, Twilight. We fucked." Rainbow sighed, causing Twilight to blush. "But we did wait till we were confident about how we felt for each other."

Twilight smiled softly and took a deep breath. "Then may I do the scan? I want to make sure your… love making hasn't put you in any unexpected danger. And if my theories are accurate."

Rainbow nodded and Twilight lit her horn to start her scan over Rainbow's body. At first she felt content at finding nearly nothing wrong. She however decided to avoid doing a pregnancy scan until she finished the rest of the scan. Once she got to Rainbow's flank Twilight blinked at what she had found. In curiosity she mentally did some calculations before her eyes shot wide.

"What is it?" Luna asked softly.

"Rainbow? Do… Do you want me to put a pregnancy protection spell on you?" Twilight asked nervously.

"Why would…" Rainbow asked for a moment before her eyes widened in shock at what she was saying. "Wait. You mean."

"You're in heat. And if I'm not mistaken. There is a big chance that you'll get pregnant." Twilight confirmed.

"It would be wise to do so." Luna suggested. "I understand you two may wish to have children soon. But you will need time to learn your new abilities and limits once the ceremony is complete."

Rainbow Dash sighed and nodded. After a moment of Twilight doing a pregnancy scan, she switched to casting the spell which only took a few moments. No sooner did Twilight finish that Rainbow nodded to Luna who lit her horn and covered Rainbow in a black orb.

Mod and Limestone carefully led the way through the room as they tried not to step on any of the remains. Between hale eaten stallion bodies and mares with bursted bellies and torn throats. It wasn't easy for anypony to take. Some of the guards that saw the room took the bodies outside to be properly put to rest after their cutie mark was put on record as being one of the victims.

Mod stopped at a large door and looked back at the other guards. "There's movement inside." She announced before her sister kicked the door open revealing a large room with an orb floating over a pool of oddly purple ooze. Along both walls were mares both stuck to the wall in the strange ooze and posed in provocative positions covered in the ooze.

The sisters looked in shock and confusion as they slowly made their way into the room. After about a few feet, a voice spoke from the orb.

"Look what we have here. A group of clever ponies, who think they caught the big bad guy." The voice laughed. "Too bad I was one step ahead of you. But hay. I'll give you a little gift for getting so close." With that the ooze started to move. "Before you join the others, here's a glimpse of what you came to find."

The orb flickered before revealing Applejack, Rarity and Fluttershy drenched in cum and bloated bellies. All three of them looked like they had just finished being ravaged by whatever was keeping them company. Mod and Limestone had to fight back their anger as they watched. Surprisingly it was Fluttershy who looked the calmest.

As the image faded, the voice returned. "You should be proud. They lasted longer than any other pony. In fact, I wouldn't be surprised if one of them becomes pregnant before you get close to catching me again." The voice laughed as the door closed behind the group. "Not that you'll be leaving this place… alive." The voice paused as the ooze started to lift out of the pool and coat the ground as it inched close to them. "I'd like to introduce you to a special friend. Did you know that there was a time where other creatures walked this land? Well. They knew how to summon an ever-growing thing called Smooze. Once I found the spell, it didn't take long to change it to fit my needs. Anyway… enjoy."

At that moment the ooze reached out for them and snatched the stallions pulling them into it kicking and screaming. Much to their dismay, as the ooze stopped inching closer to them, ponies made of slime came out of it and slowly made their way over to them.

A few guards stepped in front of the two sisters ready to fight. One of the slime ponies shot a tendril into the chest of one guard stallion, tossing him into the ooze as one of the other ooze ponies snatched up a mare in tendrils and instantly stripped her before ravaging her. Another pulled one closer and mounted her as it dissolved her armor as it started to rape her in front of the others. Each pony that was tossed into the ooze came out as one of the growing ooze ponies. Unicorns tried using every spell they thought of to fight them off. However, the ooze ponies were unaffected.

Mod looked over the door as Limestone scanned the room for another way out. "He did a good job at making this place a trap." She huffed. "But this stone does have weak spots."

"Best make it quick. There's going to be more ooze than ponies soon." Limestone huffed as she watched guards move to try and block the growing army. "Let's hope these things have a limit in how far they can travel."

After a moment, Mod turned around to face the ooze. "Good news. We can leave." She said kicking a hole in the door.

"Bad news. They'll be able to follow us." Limestone added before following her sister out. Glancing back they saw several ooze ponies following them calmly. If they don't find a way to stop them, Equestria will be in trouble. Sadly that meant they'd also end up trapping the other ponies with them.

Time for the shit to hit the fan and for Dash to go through her big change. Thoughts?
