The following morning I woke up to Mia tugging at my shoulder.

"Wakey wakey!"

I sat up and yawned widely, stretching my forehooves dramatically over my head, seeing she was wearing another miniskirt and a tank top.

She sure has a lot of sexy outfits, I thought to myself.

"Hey Mia. What's up?"

"Everypony but you. Come on fuzzpoof, let's get breakfast!"

"Okay. I'm up." I swung my legs off the bed. Mia leaned over to give me a kiss on the head and a hug. I put my forehooves around her, enjoying the warm press of her body against mine.

When she released me, I dropped onto the floor. It felt strangely good slipping more of Mia's borrowed clothes on, a clean miniskirt and tube top to give me a summery vacation look. I enjoyed wearing clothes, not necessarily because I needed to, but because I like being sexy, and clothes do things to ponies that nudity can only dream of.

"Do you feel weird wearing that without any breasts?" Mia asked me as I wiggled into the stretchy black top.

"No. Actually, though, I do have breasts under it," I replied. "It's just really hard to see them. Look."

I got back on the bed and sat down, pulling down the top and showing her my chest. "Here. Under my fur. See my nipples? Look, they're right where yours would be if you were a totally flat chested pony."

Mia looked closer. "Oh my! I see! Can I touch them?" she asked, reaching towards me.

I giggled. "You're seriously asking me?"

Mia blushed, a very unusual sight indeed. "Yeah, okay. It just feels strange because I hadn't noticed before, and, oh, I don't know. Whatever." She put her hands on me, gently pinching my two little teats. Okay, that felt really good, and I twitched my legs as a warm feeling washed over me, making me a little moist in the nether regions.

"We have internal mammary glands behind the rib cage," I said, more huskily than I intended. "So no visible breasts. Generally you can only really see the nips when we are pregnant or nursing and they push out of the fur-ahhhh!"

Mia had leaned forward and was sucking on my left teat. Having her soft lips on my sensitive chest felt quite nice, and I was momentarily debilitated from the tickly sensation, my chin rising towards the ceiling as I arched my back. If I was moist before, I was soaking now.

"M-Mia," I finally gasped, bringing my head down to look at her. "If you don't stop that, I'm going to drag you right back into bed and make you finish what you're starting."

She teased me a bit more with her tongue, making me tremble and rub my legs together. Then she leaned away and pulled my top back into place carefully. "We'll continue this later, fuzzpoof. By the way, did you know some people are certain you should have boobs down between your legs?"

I grimaced. "What? Like a cow? Why?"

She giggled. "They call them crotch tits. A lot of MLP fandom artists draw stuff like that. I used to see it all the time. They insist it's anatomically correct because horses on Earth have udders there. Here, I'll show you." Mia swept through a few menus on her holobracelet, pulling up a digital rendition of Twilight Sparkle spread-eagled on a bed, two human-like breasts stuffed between her legs near the vagina.
I wrinkled my nose. "What the hay? That's freaky. I mean, you can easily see we don't have anything there even in your animation show, right? That's so... Eew!"

Mia shrugged. "I don't even try to understand it."

"Probably for the best," I shuddered. "Do they not realize we are about as much like Earth horses as humans are like monkeys? And who wants to see humans with monkey tails?"

"Like I said, I don't even try to understand it," Mia said again. "Although I'm sure there'd be an audience somewhere for humans with ugly tails porn." Mia sat beside me on the bed, then spread her legs wide and made vulgar jerking motions between them with her fisted hand. "Uh uh. Yeah baby, show me that creepy skin buttsnake!"

I shook my head in disgust. "No. Just no. No butt snakes. No thanks. Crotch tits. Yuck. No crotch tits either."

James poked his head into the room. "Crotch what? Good morning, Eris. I can see your panties, Mia. I approve of these outfits."

"Good morning, James," I replied. "Come look at this."

He walked over, and Mia shoved her wrist in his face. He peered at the hologram of Twilight. "Hmm. Not bad, but what's with the ballsack breasts?" He paused, then looked closer at me. "That makes me wonder, though. How do you-"

I pulled down my top again, grabbed his hand, and put it on my chest.

"Ah? Ohhh! How have I not noticed this before?"

"They're kinda hidden," I suggested.

"Yeah," he replied, only half listening while he fondled my flat chest. "These are cute."

"Th-thanks," I gasped, feeling aroused again. "If you want to eat breakfast you'd better stop though. It's making me horny."

"Hmm. I like making you horny." He leaned forward and kissed me on the mouth. It was a deep kiss, too, and when he pulled me up against his chest, I could feel his hard shaft poking my stomach through his pants.

"James?" I said when i could finally breathe. "I just woke up. I probably have morning breath and I need to pee."

"You smell fine to me," he said.

"You can go right here," Mia added, licking her lips suggestively.

I groaned. "Look you two, we've got an armored truck to catch. This will have to wait."

James stood up with exaggerated stiffness and saluted me jauntily. "Whatever you say, boss lady who acts all serious after waking up late as hell."

"Slave driver," Mia added, sticking out her tongue at me. "I bet you're gonna go waste all that good pee on the toilet, too. Sharing is caring, Miss Selfish."

I shook my head as i pushed myself off the bed and trotted towards the bathroom. "You guys are the worst."

I telekinetically levitated my tray onto the food line counter, waiting for Mia to order ahead of me.

"Miss Eris! Good morning to you. That's an interesting new uniform."

I grinned back up at Cookie. "Hey! Well, we're about to go on a little R&R, so I'm dressed for the occasion."

"I've heard some of the stories," he said, frying my cheese and veggie omelette. "Sounds like you guys deserve a break. Have a good time and get some sun, Miss Eris."

"Thanks, Cookie. I'll see you later, then!"

I grabbed my tray and some drinks, then trotted to the table with James close on my heels. I slid in next to Mia, being careful with the waist belt retention holster I was wearing my Glock in. We had put our heavier weapons into lockers in our rooms, carrying only our pistols with magic-enhanced high capacity magazines installed. James sat across from me, slathering a biscuit in strawberry jelly.

I cut a piece of my veggie omelette and put it in my mouth. "Mmm. Yum. This is good." I noticed Mia preparing to eat a large jiggly spoonful of green Jell-O. "Can I taste it?" I asked.

Mia looked at me in surprise, her spoon halted inches from her mouth. "Uh, Eris, you know what this is, right? There's a reason it's not in the vegetarian section."

"It smells like fruit. We have stuff like that in Equestria."

"Is yours made from the boiled bones of animals?"

"What?"

"This is made of gelatin. It's an animal byproduct."

I stared at the bouncing green stuff. I sniffed. It smelled like limes. "Um. That sounds kinda gross, but it doesn't smell bad."

"Well if you want to try it, go ahead. You won't get sick or something, will you?"

I shook my head. "Technically we are omnivores. I could probably even eat a little meat without getting sick, but it just grosses me out too much. A lot of us are disgusted by most animal-derived products. I, well..." I hesitated. "I'm more curious than most, I guess."

James had set down his fork, staring at me with interest.

"Well are you gonna try it or not, fuzzpoof?" Mia finally asked, holding the temptingly wiggly substance under my nose.

I puffed out my cheeks and blew. "Give me the spoon."

"You ate all my Jell-O," Mia said for the fifth time as we climbed the stairs in the entry tunnel. "I didn't get any!"

"I would have gotten you more," I replied regretfully. "But the tray was empty! I checked!"

"All my Jell-O," Mia lamented again. "This is gonna cost you, Eris."

"I don't know if I like the sound of that."

"You should be very afraid," Mia said threateningly. "I'll get you. I'll hold you down and lick your hoovsies until you pass out from laughing, or I'll tie you up and tickle your butthole with a feather until you wet the bed, or something equally horrible."

"Jeez, Mia. Have some mercy. It was an accident."

"Accident? You ate all of my Jell-O, Eris. All of it! There is no way you can claim that was an accident! I wonder if your poop is gonna taste like limes?"

"What the hay are you-" I began, turning my head to look at her. I then immediately misjudged the length of the staircase, stepping off into space at the top step and stumbling forward onto the landing, my face going down and my ass going up. "Eeeek!"

"Stay just like that!" Mia exclaimed, fumbling with her backpack. "I'm gonna take a picture!"

"Like hay you are!" I reached behind with both hooves and pulled my skirt and tail back down over my exposed mare parts.

"Stop! I'll forgive your Jell-O thieving ways!" she yelped.

"I'll take my chances with the feather, thank you very much."

"I got a picture," James said cheerfully from behind us, smiling behind his ARHUD. "Came out well."

Both Mia and I turned to him. "Give it to me!" we demanded in unison.

He shook his head. "Nu-uh. That's what you get for taking off your ARHUD early, Mia. I'll give it to whoever convinces me in a way I like the most."

Mia pouted, sticking her hands on her hips. "Jerk!"

He just grinned at her. "I'll consider that offer."

She huffed loudly and continued across the staging room to the main exterior door.

As I clopped up beside her, I felt a curious mix of nervousness and excitement. It had been days since I had seen the sun, or anything besides the concrete and steel of these endless tunnels. Even so, the outside was quite a bit more dangerous than the inside. Or was it? After all, I'd nearly had my narrow ass used as a chew toy by several of the monsters in the basement by this point. Come to think of it, the collection below was probably a lot more concentrated than I would see in the jungle. I looked up at Mia, standing next to me. She looked sexy in her miniskirt, combat boots, and pistol belt, leaving me wondering if I looked even remotely as good in mine. I reached up to touch her hand with my forehoof, and she gripped my telekinetic fingers eagerly, giving me a firm squeeze. I remembered both she and James had been down here a lot longer than I had, and I had no idea the last time they'd been outside, either. When the heavy door finally creaked open, blazing daylight poured in and my ARHUD darkened. I was momentarily blinded regardless, and Mia's grip on me tightened.

"You guys ready?" James asked after a moment, putting his hand in my mane and giving my ears a quick scratch.

"Yeah," I said. "Let's go."

The three of us moved forward as one, stepping from the artificial light of the underground world and into the brilliant sunlight of the South American island morning.
