It was time. I felt it in every bone of my body. My body. It still felt amazing to think about. I looked in the mirror and did slow turns on my hooves, admiring my largely-pink form. I had grown quickly, just as I wanted to. I didn't want to spend time as a foal, so I didn't. I had things to do, things no foal had business doing.

I worried about William and his view of me for a moment. He accepted the look of the parasites, but I knew it wasn't his favorite thing. The way the mouth opened wide in one too many ways like that, it bothered something not entirely thinking in him, even if he tried to ignore it so hard, to be a good person. I really shouldn't be calling him a he, hmm. I ran my fingers along my snout as I suppressed the pattern of the parasite within me. My lower jaw fused together and my teeth became that of a normal pony. I reduced myself to one tongue, but I left it long and able. One tongue would be more than enough.

A thought sent a shudder through me. We weren't identical. We really were becoming different people. I took a slow breath and brushed out some of the fur around my belly. He would love the way I looked, and we would find a new bond, one that didn't need the same body, or exact copies. As the ache of my self-inflicted modification lessened to that of a dull throb, I spread my wings and took to the sky to find him.

Our coloration made finding us in a crowd easy. Being still larger than most and oddly shaped was also a bonus. There she was, giving rides to a few local foals and smiling. She was clearly having a good time playing horse for them. I landed nearby but watched for a moment, rather than crashing their little party. That was, perhaps, a mistake.

A moment later I had a crowd of small human and pony foals, hoping I would give rides as well, and why wouldn't I? We were still so very close in appearance, what one offered, the other surely would as easily. I did. I lowered myself to the ground and let several clamber up before rising back to my hooves. With the passengers, I trotted up to William. "Will, when are you done here?"

William smiled at me, it made me happy to see it. "Hey there, Cindy. We're just playing around. Did you need anything?"

I glanced back at my squealing payload before looking back at William. To keep them happy, I circled around William, keeping the pace up. "I need you. I want to be together, today. Dinner, talking, more. Can we?"

The foals exploded into theory and accusations of what we were up to. Some began to sing songs of marriage while others postulated that we obviously were already married. I didn't care about any of them, at least, not after William put her hands on my snout and rubbed it so gently. When she kissed me, nothing else at all mattered. It was so brief, but felt forever. "Alright kids, we have to go." Her words earned a chorus of awws from our riders, but they were well-behaved, mostly.

Soon we were free of our passengers, and trotted off together. William was looking at me, but I couldn't tell exactly what she was feeling, and that worried me. "Everything alright?"

She bumped her heavy frame against mine. "With you here? Yes." She wrapped an arm around me, and I quickly returned the gesture. Our tails brushed against one another, then gently twined as well. "It's been a week. I'm just getting used to the idea of being alone in my head, even if you are in here, nominally. You've shaped me, but now you're you, and I am me. We're our own things."

I felt somewhat relieved to hear her worry about the same things that bothered me and gently brushed up against her. "I am me, and you are you, but we..." I leaned in closer. "We are still a thing. William, do you love me?"

William went still suddenly. Her ears perked up and her nose darkened. "I... of course, I mean..."

She was confused. I could see it. She wanted to say yes, but there was something in the way. I reached for her higher belly and gently rubbed across it. "Are you thinking about me like a foal? I'm not your foal. I'm your other half, literally. I don't want the love of a parent, not from you. Sandra and Hope can give that."

We walked together in a slightly awkward silence until we reached our home. I had a room to myself, even if I often slept with all the others, but I led her there that day. She had to have known what I wanted from her, and what walking into my room meant, and she accepted it. She wanted it to work, even if some of her was confused. I pushed the door shut behind us with my magic, then circled her, no longer embraced. "Today, I want us to become full and proper lovers. When we were one, we couldn't be and felt no need. Every time we loved someone, we both did, together, and it was... good, but now, I want you, all to myself. Not forever..." I smiled gently. "Just this evening."

She noticed. "Your mouth! What happened?" She still had the parasite's jaws, and the three tongues. Had I made a mistake?

I decided to be straightforward. I flashed my flat teeth and extended my one tongue, long enough to reach for one of her nipples and flick across it. She tasted of something sweet. "Do you like it?"

She stiffened at the caress of my tongue and squirmed in place as I swirled that one long tongue around the nipple in circles. "Mmmm, it's... You're very pretty. I didn't... know you could do that." Was that jealousy I heard?

I put my hands at her cheeks. "Do you want it as well? I didn't mean to be better than you, or worse." My romantic mood felt rattled. "I'm not used to... this." She heard my worry, thankfully.

She leaned in close and hugged me warmly. "Cindy, it's alright. I... think I would rather have a normal mouth too. Can you do that for me?" I nodded quickly and gently made that a reality while caressing her snout, but any change that involved bone was sure to hurt, and I didn't stop petting and holding until I was sure that horrible pain had passed that I had felt only half an hour before. "Now we're twins again."

I smiled at her words. "Twins don't do what I want to do... Do you want to do it too?"

She pulled back a little. "Tell me exactly what you want to do."

This confused me. Was it not obvious? I turned to the side and gestured down at my cock, still stiffening into the air. Every pulse of my excited heart made it longer and readier. "I want to make love to you. I want to mount you, and be mounted. I want to... be your lover, in every way."

She flushed, but there was no ambiguity anymore. Her own member fell from her sheath and I felt a thrill surge through me. We were going to do it. I pointed to the ground. "Lay down." She looked curious, and did as I asked, slowly sinking to her belly. I rolled her to her side carefully, then slid in beside her, pressing our pony bellies together and starting to grind against her. Our shafts rubbed up and down along one another. A dim memory tickled at me as I felt our furry balls run delightfully in a thrilling caress against each other. Our balls were touching. That meant something. As a shudder ran through me, I decided it meant we were having a good time. I wanted her. The stallion in me wanted her badly.

Perhaps she was feeling the same way, because she rocked against me with the same anxiousness, grinding our slick shafts through the warm and soft fur of the other's belly. We could have gone on grinding to completion, but I didn't want that. I rolled upright and so did she without my asking. I moved around her quickly and mounted her, but I didn't try to enter her, yet. I nibbled and kissed along one of her shoulders up to her neck and nuzzled into it. "I love you, William. I love you in a way I've never loved anything before."

I felt her tail lift out of the way as she arched her back. She was ready to be mounted. "I love you too, Cindy, but you're making talking really hard." She pressed back against me. "Let's talk a different way."

I shivered a little. I was all too happy to talk that way. I hugged her with my legs as I worked my stiffness to her pouting lips. They twitched and winked excitedly, rubbing her clit against the head of my member before I could work it into her, quenching the hot steel in her furnace. I couldn't hold back anymore. I surrendered to the urge to breed and my rear hips began to thrust forward, pistoning into her in smooth gyrations that made us both moan with delight. Our voices were so alike, I realized, though mine sounded different from my perspective, as hers must have to her.

I wrapped my magic around her neglected pole and began to stroke it in time with my quickly rocked member, taking it along for the ride as I drove into her and stoked that fire inside of her. She grunted and pushed back with equal vigor. I felt her magic on my tail, gently tugging at it as we crashed together. She spasmed with delight beneath me, and my balls lifted. They wanted to unload into her, but I casually denied them. I wanted to make her squirm much more before we were done.

My hands wrapped around her from behind and I cupped her breasts, trapping her nipples between two fingers of either hand as I lifted and caressed those wonderful curves. She sang for me. The song had no words, but every tone was perfect. Every noise was one I helped to make, and I began to learn how to play her just right. By the time she had fluttered so delightfully around me for the fourth time, the urge to seed her was becoming overwhelming.

I knew it wouldn't make a foal. She was already carrying, and becoming round, but it didn't matter. It was about our intimacy. It was about our bond. I pulled her back tightly and let it go. My shaft jumped powerfully inside her tight passage and began to unleash torrents of my seed into her. I cried out with an almost delirious cry. My grip on her faltered. That moment, it was too intense. I could only ride it out on top of her, shuddering from my hooves up to my flicking ears. She had me, helpless and limp.

She was barely in better condition. She sank slowly beneath me until we were both sitting, together. I was buried in her warmth, and she was... laying on the wet spot I'd helped her make. I blushed with embarrassment, but she laughed. "Next time, you get the wet spot."

Author's Notes:

Cindy claims William as a lover, officially, but, perhaps more profoundly, establishes herself as an individual. Her thoughts are not William's, even if they share many things. Their typos are their own.

I hope I haven't made anyone too sad with them choosing to go to mostly-not-tatzl. Neon and Sandra pull off the look so much better!
