I awoke to darkness. Confused, I sat up quickly, or tried to. Sandy was still resting on me. The sudden aborted movement got her up with a soft noise and she rolled off, allowing me up. Throwing my legs over the side of the bed, I asked, "Did you turn off the lights?"

"No." Her reply was sleepy, punctuated with a yawn.

I got to my feet and began feeling my way through the dark and soon arrived in the living room, where some light filtered in from outside. The light seemed... off. Maybe I was just waking up, but I couldn't quite focus on it.

A new voice suggested, "Maybe you need glasses." The voice was just a few inches to the left of me and I jumped in surprise, but nothing came closer to me.

I heard the clip-clop of Sandra from the bedroom that stopped in the hallway. "William? What happened to you?"

"Happened to me?" I started patting myself down. Legs in the right place. I had hands, torso felt normal, legs in place, no hooves anywhere, oh there it is. I had a second head, of course. Why wouldn't I ha-- Oh shit I have a second head!

"I didn't ask to be here," said the second head that I couldn't see in the darkness very well. It looked equine though, and had a horn like I did. The voice was also soft and feminine. "Since we're stuck together, we can at least be civil about it?"

Alright, so my second head was polite by the sound of it. There could be... worse things? No there couldn't. I sank to the ground and thumped it once, as if attacking the earth would properly display my fury at the situation.

Sandra stepped up closer to me and I could hear her sniffing softly. "It's part of you."

"Of course it's part of me. It is... me, sort of? So, do you have a name?"

The second head smiled. I'm not sure how I knew it did, but I did. "You can call me Cindy. It's dark in here, let me fix that." Her horn lit up with a golden glow, allowing us to see clearly. There was a smiling unicorn head beside my first. She looked friendly, but that didn't make it a bit less creepy.

Sandy seemed to be taking it a bit more in stride. "It's a part of you," she repeated, as if that was all she needed to know before she reared up and sniffed at the new head. The unicorn, er, Cindy's tongue flicked out when Sandy got close, licking her nose. Sandy smiled and leaned in and before I realized what they were doing, there were two horses kissing deeply on my shoulder. Sandra's hooves wandered over my front, caressing me as she tongue-tied with Cindy. The day couldn't get much stranger, I was certain.

I pushed Sandra back carefully. "Easy there, this is weird enough without having parts I didn't have yesterday initiating hot kisses that I feel detached from."

Cindy tilted her head a bit. "You think it's weird? Imagine it from my view. I didn't exist yesterday, but here I am, with most of your knowledge I think, and some other things beside. I don't want to be a helpless freak, but here I am. At least I have magic, and a very friendly friend." She smiled at Sandra.

Sandra bobbed her head. "Our herd grows." Her tail began to sway animatedly, sweeping against the floor. "How are we going to make breakfast without power?"

I nodded at Sandra. "Right, good question. Utilities are out, which just made the survival game a lot harder. It was stupid of me to expect them to stay on. All those TV dinners are basically worthless."

Cindy pouted a little. "You're doing your best. Don't be hard on yourself." Great, my second head was giving moral support.

I brightened a bit at a thought. "Say, Cindy?"

"Yes?"

"You seem to know how to use our magic, right?"

"Yep!"

"Great! So what can you do?"

Cindy frowned with thought. "I can make a force bubble, grab things, make light, make heat, and detect magic around me. I'm sure we could do other things, but that's all I know how to do right now."

Sandra smiled widely. "You can make heat? We're saved!"

I nodded in agreement. "You just earned your rent. Let's attack the frozen food since it'll go bad the fastest." I got back to my feet and moved to the kitchen, easily navigating with Cindy's glowing horn. I realized that my vision was partially split. I could see through her eyes if I focused on it. We really were attached. "What am I becoming?"

Cindy answered, to my surprise, "I'm not entirely sure, but you're far from done. I'll be with you every step of the way, promise." As I dug out some food from the nonoperational freezer, I glanced at Cindy, looking her over. She had the same light-pink fur as our horns. Her 'mane' was a bright pink, long, and flowing. She had very human expressions, as most of the ponies I met had, and she was currently concerned. If I had to get a second head, a nice one was at least the best I could hope for. She cooked the food under a golden ray, bringing them to steaming hotness faster than a microwave could, which alarmed and amazed me. She took control of an arm suddenly, grabbing one of the three trays and bringing it to her mouth to dive right in.

Sandra took a tray for herself and sat with it, watching me. "Don't you both have the same stomach?"

Cindy had no answer for that. I took up the remaining tray and ate as well as I could with only one hand under my control. I didn't feel double stuffed, but I was starting to give up on trying to rationalize this. Maybe it was all being used to fuel my bizarre change? "Well, I guess you're coming with me, Sandy."

Sandra brightly smiled. "Good! I don't want to hide in the dark."

I nodded. "Exactly. I didn't even bring back the flashlight I found. God, that was stupid. This changes our priority by a lot."

Sandra looked like she was about to reply when she fell to the ground with a whimper instead. Her hooves brushed over her snout over and over. I reached for her, petting her on the back. "What's wrong?"

"Hurts...." She clenched her teeth hard enough to make her jaw bulge and her whimpering turned into a short-lived cry as her jaw split apart wetly. The pain must have been bad as she fell over at the very moment and lay there, breathing.

"You... alright?"

"No..." She slowly sat up, then opened her muzzle. "What happened?" She held her mouth open for me. She looked pretty normal, at a glance, but I leaned in and could see her tongue swelling and splitting.

"You're becoming one of those long-tongued ponies. Try, uh, splitting your jaw."

Sandra looked appalled at the idea, and Cindy offered encouragement. "You'll be alright. You can use them like hands. Won't that be nice?"

Sandra let a tongue hang free and moved it around experimentally. The wet limb was quite jerky and unsure at first, but she was improving. "Oh wow," she says with a slur before her jaw unhinged on its own, allowing the other tongues free to wave in the air. Sandra panicked, which just let them loose, flailing around her a moment before she could draw them back and close her mouth, breathing wildly.

I felt bad for Sandra, but I wasn't sure which won out for freakiest new ornament, a new head, or the tongue package. "You aren't going to get those tongues, are you Cindy?"

"Nope! I feel very stable, at least my head does. The rest of us, not so much."

That was not as reassuring as I'd hoped. I reached for Sandra and softly stroked behind an ear, which helped calm her down. "We'll pull through this, together."

Sandy nuzzled the petting hand. "Thank you for not leaving me alone, that first day. Say, I think I saw a radio in here while I was digging around." She hopped to her hooves and dashed off. I could hear her digging around and she returned with a battery operated radio held in one of her tongues, wrapped around the handle. She set it down in front of me. "Your other head wasn't wrong. They are good for grabbing things."

I grabbed the radio and got it on quickly, cycling through stations. Most of the band was static, but an AM station was still faithfully broadcasting. "--vised to stay indoors. The army is coming to take control of the situation. Your safety cannot be guaranteed if you're outside. This is a biohazard alert. Stay inside, lock the doors and block your windows. Do not attempt to find help. Do not open the door for anyone that doesn't identify themselves as law enforcement or a military agent." The message started to loop and I clicked it off.

I sighed and put a hand to my head. "Well, great. How much do you want to wager they'll be shooting first and asking questions never?"

Sandra tilted her head. "We could surrender?"

"And spend the rest of forever in a lab somewhere?"

Cindy snorted. "No, thanks."

"What she said."

Sandy laughed at me talking to my other self. "You're getting used to that."

I frowned a bit. "I could freak out some more if you prefer?"

Sandra sat up and held up her forehooves. "I'm not trying to insult you. I'm... very happy you're here, and being so strong." Her eyes went downcast a moment before looking up at me again. "I think I love you."

That felt like an odd way of putting that, but Cindy didn't mind at all. She was smiling warmly. "I love you too."

Both of them looked at me expectantly. I was on the spot. Did I want to join the love circle? Well I did like Sandra a lot, and we were literally stuck together. I reached for Sandra and pulled her up into my lap, stroking down her sides and back like I would a dog or a cat. "We'll make it, together."

Sandra seemed to accept this answer, and nestled close. "We should get going, while it's light outside."

I considered that. "We don't really want to be seen. The dark may be better now, especially since we have a lot more to fear from humans with rifles than short-ranged ponies that are more likely to violate our space than to actually kill us."

Cindy tilted her head. "I could call some ponies to us?"

Sandra and I blinked as I asked, "You can do that? Why?"

"I don't know why! I just feel pretty sure I can. I don't know what pony'll show up."

I held up a hand. "We'll save that for an emergency."

We settled into quiet. I pet Sandra, and she nuzzled me, and the day passed slowly. Eventually I got tired and laid down, and Sandra curled beside me, until I felt her nuzzling at my belly and working downwards. Those tongues of hers slipped out and went right under my belt, seeking out 'Little William' in a slithering search. "Sandy! What are you doing?"

Sandra drew her tongues back quickly. "I'm bored, and you're tense." Her tail swayed slowly. "Why not?"

A thousand reasons why not flashed through my mind, but most of them felt hollow. However freakish she was, I was no less a freak, and destined to become more so. Cindy nudged me with her snout. "We'll both feel better."

*** Clop Start, look for clop finish to skip ***

Outvoted by my own head? Great. I reached down and undid my pants, pulling them and my boxers off. Sandra looked excited and tapped at the ground with a hoof. "Lay down." I did so, watching her with a mix of caution and curiosity, though the first quickly melted as she wrapped one of those tongues around me and began to undulate it up and down. I grew rock-hard almost instantly under her care, and she coiled more of the tongue to capture the entirety of my member, stroking me firmly. I felt like I was still getting erect, vision swimming with a pulsing that ran all through me.

Cindy moaned throatily. "Oh that's good... something... something's changing."

I could feel it too, and it was coming from the massaged cock. I looked down at Sandra's handiwork and saw that it was swelling larger and becoming pink and mottled with brown. The head flattened and dense white-pink fur encased the bottom and over my balls. I was growing a horse cock, and while I should have been upset at that, it felt too good to think much but wanting Sandy to keep going, but she didn't. She drew back and circled away. Her tail raised high in an offer that Cindy seemed to respond to instinctively. I knew what it meant, and I wasn't in a mood to deny it.

I got up behind Sandra and lined up the member with her sopping wet passage, pushing the blunt edge into her. She was wonderfully tight and wet, engulfing my member in heat as she drove back against me with a shuddering groan of pleasure. "Take me..." Who was I to deny a girl? I grabbed her hips and pulled her back against me as I thrust forward, piercing to the hilt and drawing a sharp yip from her before I drew back. We quickly learned each other's patterns and started working against one another, pistoning smoothly. My big furry balls jumped as something brushed against them. Her tongues had come back out and worked over them, trying to tease the seed out of me. My eyes were clenched shut, the pleasure growing to a fever pitch all too quickly before I spilled. My engorged member twitched and jumped inside of her and I could feel the hot seed forcing its way out before spraying wildly into her willing body. She clopped against the ground, riding her own trembling release before we sank together and curled on the ground.

*** clop finish ***

As I regained my breath, I considered what I had just done. Cindy seemed to have less reservations. "That was lovely!" She licked over her snout. "How do you feel, Sandra?"

Sandra slowly worked herself around to face me instead of away from me and nodded her head. "I feel much... better."

I leaned in and kissed Sandra's furry little snout and she gave that curious little purr into it. "Be ready to go when it's dark." She nodded at me, an we slipped off to rest in one another's embrace. The situation was looking a bit more grim than the day before, but we had each other at least.

Author's Notes:

Our heroes take a firm step out of the mundane in this chapter as they get to experience the joys of power loss and impending military invasion. Surely things can only go up from here!

I'm told the soldiers fire typos from their gun. Nothing is more painful!
