Crystal returned a few minutes later. "Liz got her battery."

I suddenly had a question. "So, wait. Humans turn into her kind of pony, but does another kind of pony have a time limit?"

Crystal shook her head. "I don't really know. Maybe not, but that could be a good thing?" She rolled a hoof. "It means they wouldn't have to raid to survive and grow, like a cancer. It wasn't... so bad in there, but I have work to do. But before we do that." She circled around me. "We should talk, in private."

I followed after her to a small room where she pulled the curtain shut and smiled. "We made a little promise, don't forget."

"What promise?"

Cindy suddenly spoke, "You said you'd let her fuck you afterwards, which is now."

Crystal pointed at Cindy. "That. Now that I have the parts, your scent is calling to me. It feels great to have those thoughts again without revulsion and horror with it."

I wrinkled my new snout. "I'm still in that part of it."

Crystal moved up behind me and I felt her smooth snout rubbing against my nethers, which were quite warm and wet despite my complaints. "You don't look like it. Are you just afraid? I'll be gentle..."

I felt my tail raising out of the way on its own, or did Cindy do that? "Uh, you're also smaller than me."

Crystal softly nipped at my legs. "Then lay down and let me take care of it. I've watched my ponies going at it like rabbits long enough, it's my turn."

Cindy's thoughts entered my mind, ~ It'll be OK. You like Crystal, don't you? ~

If I had to pick a person I liked the most, it'd be Sandra, but she didn't have those parts, and despite my objections, Crystal's attention was turning something on back there something fierce, and the idea of letting her have her way with me was becoming less and less scary. She suddenly ran a warm tongue across my new swollen lips, and I crashed to the floor, legs refusing to hold me up anymore. Cindy wasn't shy about moaning out her pleasure even as I struggled with it.

"Go ahead, do it," encouraged Cindy. "We're ready."

With permission given, Crystal hopped up onto our back and shuffled forward, pressing her marecock against our winking vulva. She let the twitches of her sopping wet sex drag it back and forth across her throbbing tool. "Our foal will be the next generation of leader, when that time comes. It's our job to make sure they have a future to lead."

I couldn't help but laugh a little. "Do you have to play up the leader angle while fucking?"

Crystal perked her ears, then huffed. "It's how I feel, sue me." She slipped her hooves around my barrel, hugging as she pressed forward, piercing into the hot wetness of my new tunnel. My shaft ground against the earth, turned on like the rest of me as she worked her way forward inch after inch. She wasn't as large as I could take, but my passage clenched tightly around her, gripping it and milking it urgently. "Nnng, or should I say 'fuck you'." She thrust her hips forward, pushing into the hilt.

~If her gift had even the slightest spark, I would make her so large right now,~ came Cindy's lustful thoughts, and I was glad Crystal had gone stable. She felt just fine, if you ignored the part where you didn't have a cunt a week before. I could feel Cindy's pleasure like a gentle echo of my own, and my reservations were chipped away. We began to rock back against Crystal, urging her onwards as our bodies met with loud slaps.

All-too-quickly, her shaft began to jump and twitch, firing heat deep into our body and soothing the burning itch that I had been ignoring for a while. She sagged against us, panting for breath, but holding herself close, letting her shaft empty itself into our willing form. We hadn't reached our own climax, but it felt good the entire time. We relaxed with her, catching out breath when we heard her suddenly gasp and start squirming, driving her shaft into us at a new angle. "Who's doing that?" she growled.

One of her pegasi had snuck in and was lapping dutifully at Crystal's exposed cunt, working her right back up. The mare nuzzled into her leader. "You look so happy. Please, go on."

Crystal flushed darkly. "You're not supposed to, mmm, be here right now. Go!"

"No," refused the mare before she buried her tongue into Crystal, sampling her and teasing her, soon getting Crystal to start thrusting into us all over again as her passions were reignited. The mare was not the only, just the first. An earth pony dug out of the ground beneath us and took the head of our shaft into her mouth, nursing eagerly. Cindy and I groaned in delight as the cock was consumed into that warm tightness, and we rocked between Crystal's shaft and the inviting gullet of the pony beneath us.

A third pony wandered past us, his tail swaying with every step as he came up to our front and smiled. I looked at him quizzically, but couldn't really focus with the intense feelings bursting from both sexes. He didn't keep us guessing long as he went up and kissed Cindy passionately, his hooves cupping and caressing over our breasts. He paused just long enough to whisper, "I've missed a lover with real breasts." He buried his snout between them and nuzzled the warm furry space between before moving to kiss me next.

A small part of me recoiled to be being invasively kissed by a stallion, but climax struck, and I pressed into the kiss while our shaft pulsed wildly, spraying seed down the throat of the pony beneath us and we pulled manically at Crystal's rock-hard shaft, drawing their second release free of them forcefully.

The ponies that had joined us never tried to stop us from coupling, or attempted to mount Crystal, but they eagerly added to the pleasure, and kept us going. The rest of the day was spent in a blur of passions until hunger drove us to eventually seek dinner. I was certain I had been inside the earth pony from both ends at some point, but I couldn't prove it, with her out of my sight. All three fled when we called it quits, the pegasus and the pony in front of us darting out the door, while the tunneler vanished into the earth.

Cindy let out a satisfied sigh. "Your herd is lovely."

Crystal shuffled a bit, seated on her haunches. "They really love me. I think they're happy I'm willing to 'play' now."

I got up to my new hooves, wobbling a bit, but finding a stable stance soon enough. "We should... focus on finding peace, or we'll get lost like this and die with smiles on our faces and little else."

Crystal nodded in agreement and we went to find dinner and discuss future plans.

Author's Notes:

Crystal got what she wanted, and William gets more comfortable with his (her?) new self. Next time, they have to face the more violent herds.
