Growing in Love

“Do you think it’s like this for Luna and Celestia?” I asked White Heart.

“I don’t know,” said White Heart. “I mean, there are rumors, but I never got the impression that they were actually… intimate.” He thrust his hips, slamming a few thousand light-years of cock into my pussy.

I laughed. “That’s not what I meant. I mean, it’s been millions of years, hasn’t it?”

“It has,” said White Heart. “I mean… there’s no night or day when you’re bigger than any sun…”

“But you can still tell, right?” I said. I leaned my head back, and White Heart nuzzled the back of my neck. “I can tell too… I was just wondering if this is what it’s like for other alicorns. Living this long, feeling time pass… and yet every moment feels entirely new.”

“I feel that way too,” said White Heart. “But I think that’s because I’m with you, Fluttershy. Whether or not we’re bigger than the cosmos, every day with you was always perfect.”

“And I bet it doesn’t hurt that you also have an endlessly growing cock, does it?” I said, “A cock that stretches from one end of the universe to another, shooting bigger and bigger loads of cum into my cosmic pussy?”

My words made his cock pulse with arousal, shooting a gush of cum big enough to extinguish a galaxy’s worth of stars deep into my marehood. White Heart was always coming, just like me, but there were still things I could do to make things even better for him.

“Nnngh,” grunted White Heart. “Yeah, it’s not bad. I’m glad we can be big together…”

At that moment, I saw something new. Cracks were beginning to form in the swirling color around us, exposing brilliant light on the other side. “White Heart,” I said, “We’re breaking through the edge of the universe… what do you think is going to happen?”

“We’ll keep growing,” said White Heart. “You and me, growing bigger and more powerful, making love forever. No matter where we are, that’s what’ll happen.”

The cracks in the edge of the universe grew bigger, like a pane of glass breaking in slow motion. And then it shattered, and the light from outside the universe flooded in, bathing the two of us in colors more brilliant and beautiful than any I’d ever seen. The whole rainbow was more vivid than it had ever been before - and I would have marveled at it with White Heart, except that something else started happening at the same time.

“Wh-White Heart…” I groaned, my whole body quaking, “We’re… we’re growing faster…”

“Oh… oh wow…” gasped White Heart. “Something happened… when we broke through the edge of the universe… my magic’s getting stronger… oh, oh, m-my cock… I’m cumming so hard, Flutters, I can’t…”

“Ooh, fill me,” I moaned. “I can feel it all… your cock is as long as the whole universe, and I can feel every inch in my pussy… shooting enough cum to fill all the darkness with hot, thick, white… make me big, fill my belly...”

I reached my hands out over my breasts and felt them expanding. I could never reach all the way around my tits, because my nipples were light years away and getting farther every second - but I could feel them growing faster than ever. My round belly was growing right along with them, swelling bigger as White Heart’s cock launched geysers of cum so big that they could sweep away galaxies. Those big, handsome balls of his were forever churning up more wonderful white cum for me - and we were growing so fast that just one of his balls was already as big as the universe we had just broken out of.

I could see other universes out there, dim spheres that gave off a bit of inner light. In time, the two of us would decide to call the space outside of universes “hyperspace.” But in the aftermath of outgrowing the universe, we were too overcome with growth to have much of a conversation. In the millions of years since we started growing, we’d adjusted to the feeling of constant orgasm. It never got less intense - quite the opposite! But we’d managed to get accustomed to it.

But now, outside of the universe, out in vivid swirl of hyperspace, we were growing faster and coming harder. In a little over a minute, White Heart’s cock was so big that one gush of cum could have drenched hundreds of the little universes floating all around us. And all that cock, all that indescribably long and thick and wonderful cock was inside me, thrusting and coming over and over again in my pussy.

And I was coming just as hard as him. My pussy pulsed with endless climax, each throb producing enough energy to bring entire universes into being. For the first billion years after we broke through into hyperspace, White Heart and I barely spoke in more than moans. The climax was simply too intense, even for us, and so we simply held onto each other, crying each others’ names, feeling each other grow.

A billion years is a long time for two ponies to barely speak, but when they share the kind of connection that White Heart and I have, no amount of time can come between them. And it didn’t hurt that we were fucking the entire time, experiencing an eternal shared orgasm.

Throughout all that time, the universes floating around us dwindled in size, smaller than pinpricks, smaller than atoms. But I could feel each one rebounding off my skin - some bumped gently against my swollen, sloshing belly, others against my sensitive pink nipples. The tickling sensation was slight, compared to the orgasm that was perpetually rolling through my colossal body, but it was a pleasant reminder of just how big I had become.

Sometime in the first million or so years, I had the idea to reach out into one of those universes with my magic. I was unaccustomed to using magic, having only become an alicorn after leaving the planet, but there was so much power in my immense body that I found it easy to hold onto a tiny little universe. It was remarkable how much of it I could feel, just by holding it in my aura - my magical senses could touch all the love and life inside of it.

And with so much power at my command, I wanted to do something for the tiny little creatures whose universe I was holding. All throughout that little universe, women’s bodies began to grow. Without warning, across every galaxy, their curves ballooned outward, breasts and butts swelling to tremendous sizes as they tingled with pleasure. For a brief moment, I was a goddess to that universe, sharing the blessing of size with the little people within… and then I released it, letting it drift back into the vibrant glow of hyperspace.

For hundreds of millions of years, I repeated the process with the universes that floated my way, blessing them with growth and pleasure. With only an infinitesimal fraction of my power, I sowed love and passion and magnificent growth through countless universes… all while White Heart’s godlike cock pumped bigger and bigger loads of cum into my divine marehood.

And at the end of that billion years, the two of us released long, heavy breaths, our faces flushed, and we found ourselves once again able to speak. The intensity of our eternal orgasm was still growing, but our minds and our mouths had finally caught up.

“Oh my goodness,” I said, turning my neck to look back at White Heart. “That was… really something, wasn’t it?”

White Heart gave me a smile. “You haven’t lost your knack for polite understatement, I see.”

“Well, I could hardly overstate it,” I said. “There simply aren’t words to describe how wonderful it feels to make love with bodies this big. And there’s no word that can describe how long and thick and fantastic your cock is, my love.”

“Then we can continue to let our bodies do the talking,” said White Heart. “Your pussy is very eloquent, in its own way.” He turned his eyes upwards, towards my long yellow horn. “By the way,” he said, “I saw you started to hold onto universes with your magic, so I started to try the same thing… and I found out I could share a little of our fun with the people living in them.”

“That’s what I’ve been doing too,” I said. “The two of us can be gods to those little people… giving their universes a little push, whenever they need a little more love… or bigger boobs…”

“That’s the Fluttershy I know,” said White Heart. “Always looking for ways to help.” He looked out at the bright glow of hyperspace. “Maybe someday we’ll outgrow this too,” he said, “And we’ll be big and powerful enough to share this blessing with everyone who exists, everywhere.”

“Of course we will,” I said. “We’ll outgrow everything. We’ll grow together, forever.” He leaned forward to kiss me, and I pressed my lips to his. It was a wonderful kiss, warm and passionate, good enough that I wanted it to last forever. Or at least for the next million years.
