“H-Honey?” My husband asked. “Are you sure about this?”

I rolled my eyes. “Of course I am, sweety. We're here to be dangerous, after all.”

“Don't you mean in danger?”

“Honey,” I said with a directness in my voice. “The concern at first? It was cute and sweet.” A fine, circle line of the massive shadow was before it. Round and vast. Upon stepping past that line, I stopped, sighed, then turned around. “But you really need to drop the act.”

Shiny slowed to a stop before the shadow. He stood in on the sheets still covered by light—my light being snuffed by the massive, titanic cheek of butt to my right. Round and filling out, soft and squishy, everything covered in trim, midnight blue fur.

“Cadence, it's not an act!” Shiny stood before the line of shadow. “Do you know everything that can go wrong? Just look at how big Luna is!” He shook his head. “What if she rolls over while we're climbing her? What if we get crushed in her... y-you know!”

“Pussy, Shiny.” I sighed. “And don't be one.” Turning slightly, I gestured a hoof to the massive ass next to me. “See all this? Everything is dangerous. All can go wrong. If it didn't, where would be the fun?” Letting my hoof dropped, I took a breath, and approached the line of the shadow—the fine thing separating us from each other. “There's more risk being on this side, but there's also adventure and excitement.”

Shining lowered his head, but his ears were still perked, listening to my words.

“And that's what we need.” I kept staring at his dejected form, hoping he could feel my gaze, that my uplifting words would cease his worries. In truth, I was speaking from the heart as much as I was from my loins. “You don't have to join me, Shiny. But... if there is to be anything done about our sex lives.”

Shiny looked up at me, his head still down, his gaze hopeful.

“...then it probably lies inside Princess Luna's pussy.”

Shiny lifted his head and rolled his eyes. Afterward, he sighed. “Everything has to be dirty afterward, doesn't it?”

I giggled. “Hey! I'm not wrong.” Turning half-way around, I let him see my smirk. Both of us looked up at the colossal rump set before and above us. “I just like to end my points in a sexy manner. You used to appreciate that, once upon a time.”

I heard Shiny huff.

I heard Shiny walk.

I felt Shiny brush my side.

“You really are a crazy mare.”

I giggled. Here we were, a couple standing close together, gazing up the giant, right flank of one of our friends. We didn't move for a while. Simply, we enjoyed the sight, and how we felt pressing together.

“But... if I was willing to get in trouble for your crazy antics back then,” Shiny said to the left of me, causing me to glance that way, seeing only the end of his muzzle—which was pointed up to our destination, “I see no reason why I won't suffer for you now.”

Another giggle: my charm. “Don't lie. You just wanna get fucked with me in some mare's giant pussy.”

“I neither accept nor deny that claim.”

“A guard at heart... and in his princess's pussy.”

“Shut up!”

Climbing a giant butt was... strangely enjoyable?

Dunno. Never expected to climb a mare's ass before. Touch one? Sure. Slap one? Cadence giggled and moaned when I did. But this was a new level of... whatever the heck it was we were doing. Right now, we’re climbing along the slope of Luna's right cheek.

The cheek itself impressed when we set our weight against it. It helped give us grounding... among other things. Cadence was quick to tease: scorning me for climbing another mare's ass. She took a crack at my cock when it became fully erect. From what I could tell, she was getting off to all this as much as I was.

It wasn't before long that we made it up the slope. It was... still crazy to consider all this. We'd spend the last ten minutes climbing the massive, round cheek of a mare. Right now, we stood atop her thigh, our hooves sinking into her flesh, our fur comforted by her softness.

“Will you look at that!” Cadence's voice drew my gaze. Looking to my right, I saw her pointing a hoof to the sight before us: the vast, long, and wide dark-blue underbelly. At once, I thought back to when Cadence had me on her massive belly.

This was her first time taking in such a sight.

“Crazy.” Cadence glanced over at me. “Right now, we're standing on Luna's thigh.” The idea made her giddy. “And just look at how big her face is! Her mouth is even open a little! Imagine doing the dirty in there, huh?”

I blinked. “In this relationship, which one has the penis?”

“Literally? You.” She pointed a hoof at me. “Metaphorically? Me.” She pressed the hoof against her chest. “Who has the massive pussy that's going to swallow us whole?” Cadence's hoof swung from her chest, pointing across the vast expanse of trim, soft, dark-blue fur, directing it all to the giant alicorn's chest.

I gazed at the sight before me. Luna's giant muzzle loomed in the distance, blurred by how massive her face was, her eyes, round as a star, closed tightly. Even though she was asleep, gazing at Luna from her thigh still scared me.

All of this... was her body. Wherever we walked and wherever we went, it was all made up of little details you never considered, now planes of land. I'd never look at my stomach and imagine how big and wide it was—no. It was just a thing I had.

But now. Luna was her own world. And if our steps, even if tiny, woke her up... there was no telling what she'd say or do. But even with that threat in mind: Cadence was right. Walking across another mare's body with my wife was sexy as fuck.

Cadence turned to me fully. “Are you ready to get to it?”

I nodded my head. “Sure you don't want to explore a bit more?”

“My, aren't you asking better questions.” Cadence glanced over at the expanse of Luna's underbelly, seeing how far and how wide the distant belly and chest went, pondering. “It would be hot, wouldn't it? You riding me from behind, both of us on her chest, rising and falling with her little breaths.”

My cock twitched.

“Picture it, darling.” Cadence shivered. “Luna's giant eyes opening up! They'd blink a few times, this small little thing we all do, now utterly gigantic to the both of us. Doesn't that turn you on? How the small things suddenly become everything here?” Cadence spoke a little faster with every passing word. “Her eyes would open, her sleeping disturbed by something small, and then, she would make out two specks on her chest... and wouldn't you just want to know what happened next.”

Walking next to Cadence, I threw my hoof around her neck. I pulled her head against my chest, and without another word, turned to the other side of the thigh. We took a few steps, her confused but not saying a word, stopping once we were gazing over the abyss.

“Oh my.” The words left Cadence's lips at the sight. Down in the valley below, Luna's thick slit was exposed to our sights. “Luna's... pussy.” Below my chin, I saw Cadences eyes flick up to my own. “We're actually going in there? We're really going to do this?”

I nodded. I tugged us along the thigh, feeling the skin impress underneath our steps. The field of fur tickled our own. We walked off her thigh, stepping onto the giant mare's underbelly. Here, walking became dangerous. The breaths that raised her chest also snaked a push against her stomach.

Not much longer, however, we were in-between the pair of massive—and climbing down. We were careful with our steps, making sure we found purchase in Luna's softness before taking another step.

“Hey... Cadence?”

She was next to me, careful with her steps, approaching the top of the pussy. “Y-Yes?”

“You know you can fly down, right?” I said. We were coming along the top of Luna's vulva. The surface was thick and wide enough to hold us, though impressed more than the rest of her body. “I can meet you down there.”

“Hun?”

“Yeah?”

“Half the fun of this is climbing Luna.”

“Whatever you s-s-say—” Oh shit. Coming down the slope leading onto the top of Luna's pussy, my hoof had sunk in a little too deeply into her vulva—sending me off balance while my momentum pulled me forward. “C-C-Cadence!”

I turned around too late. My other hoof slipped off the top of the dappled vulva. While my body turned in the air, all I could see was the shrinking sight above, my wife standing atop the thick vulva, eyes wide and wings flaring.

She jumped after me.

We fell, I faster than her, and my heart raced quicker than anything else. Was this it? Captain of the Guard, dead not from foe or spear, but rather, from tininess and because of a giantess? I shook my head while I fell—screw that.

So I reached my hoof out—for anything. Before me, the towering slit filled my gaze, blurring while I fell, this impassive thing. The wind whistled into my ears. My speed became terminal. Something extremely soft would have to break my fall.

Cadence had found a solution. While she fell toward me, she flapped her wings in assistance, gaining speed but losing space between us and the mattress below. Hitting the sheets wouldn't save us: it'd make us go splat than anything else.

Which was why that, when Cadence finally caught up to me, she flew next to me. Her expression was exerted. Only after a few seconds did she glance at me, smirk, then flings herself at me.

Her body slammed into my own, her hooves wrapping around me, as the impact shot us forward—right into the giant lips of Luna's pussy. At once, the thickness and softness of the mounds slowed our speeds, squeezing us the further we went.

My hooves had wrapped around Cadence by instinct. Holding onto each other tightly, we slipped through the mounds, which became looser with time. Soon, it'd broken our speed... but not quite our fall. With the lips of Luna's pussy not enough to hold us, we fell once more, only this time, slowed by her sides, the drop still very much within the confines of her entrance.

“Uck!” We slammed against the softness, the impact splitting us. We rolled away from each other, our fur rubbing against the flesh, until we came to a stop. Feet away, we rested for a bit, breathing, glad to just be alive.

By the time I was able to open my eyes, I was blinded by the light, and almost unable to believe the sight. I gazed out from the bottom of Luna's pussy, seeing her thighs above and before: her massive legs stretching on into blurriness.

Even more scary was where I rolled to: at the lips of Luna's pussy. Below me, I couldn't see the mattress beyond the haze—but I could see Luna's puckered asshole. Furry along the surface, dappled in a few places, able to swallow me easily without its owner knowing.

The metaphor of Luna being her own world seemed to become more true with every passing second we explored her body. But I shook my head. Following such thoughts didn't do anything for Cadence or me.

And even when I got to my hooves, stumbling in place while I did so, even then I was forced to acknowledge the aching between my legs. My cock dangled below the white fur of my stomach, erect despite near death.

“Hnnngh... oh my...” At the sound of her voice, I spun around and caught sight of my wife. She was slowly rising to all fours, shaking her head while she did so, snout twitching. After a few seconds of standing and blinking, she glanced around. “My... oh... oh wow...”

Cadence craned her neck up, looking along the wall that was Luna's left mound. It protruded out toward her. No matter how hard she craned her neck, she couldn't stare all the way up, deciding she'd seen enough to know where she was.

Then she looked over and saw me.

“S-Shiny! You're alright!” Cadence stepped toward me, both of us standing at the entrance. “You're okay? Anything broken?”

I nodded. “Alive and well inside the giant pussy.”

“I swear, you.” Cadence shook her head. She then looked out to the world from in-between the massive vulva, taking sight in the wonder and sexiness of it all. “You get sexier every time we fall.” She glanced at me. “Should we take a leap now?”

I chuckled. “Where you wanna go is behind us, honey.”

Cadence licked her lips. “Good answer.”

It still killed me in the end. Even when my wife walked past me, swaying her hips while she did so, that she was leading us deeper into the cunt of another mare. In truth, it all got me hard. Luna was a beauty in her own right—what stallion didn't want to be with her?

But a guard knew when to keep such thoughts at bay.

And this husband knew when he needed to please his wife.

It's neat.

Very neat. Even as I look up at the towering dark-blue mounds, I'm reminded I have the same thing between my own legs—something that, with every flick of my tail, I'm exposing to my Shiny. Still, it's weird to see another mare's pussy up-close... and so large that you can just walk right in.

“Well?” I said upon looking back, seeing Shiny following slowly. “We've made it this far!” I gazed forward again, seeing the walls that were her folds just ahead, where the light became dimmer with every step. “We're at the entrance of Luna's pussy of all things. You and I, about to enter another mare... oh, I can't take it anymore!”

I must admit that I did blush a little upon breaking into a gallop. Everything about this was making my own thighs rub together! Luna's pussy echoed with our steps, quivered slightly at our movement, this thing that it was its own world, only connected to something—and someone—so much bigger.

“It must have been like this in my panties, huh?” I said into the air, only coming to a stop when I reached Luna's folds. In her sleep, Luna had shifted a little, raising her rump slightly, causing her vulva to clap tightly together—each wall of softness pressing against me, causing me to squeeze through them.

“To think that of this giant mare, only the inside of her pussy is of scale to us!” I couldn't stop myself! My loins were being set ablaze by the idea of it all! Rearing myself onto my hind legs, I let my forelegs grab the bottom of the towering folds, trying to hold as much as the softness and skin as I could manage. “She could be going about her day while carrying us along! A part of her body becomes our world! Oh, Shiny, do something to me!”

I could only hear him chuckle from behind, but his chuckles grew louder nonetheless, stopping behind me. I had myself read for him—flank out, tail aside, pussy exposed. His hard forehooves rose and sunk into my flanks, massaging my softness while his cock prodded at my slit.

And then his cock slipped into my slit. I moaned as he rode me, grabbing harder and harder into Luna's fold—at one point biting into it. Despite our loud moans, an even louder rumble rocked from around and beyond, but we were too horny to care.

“Mmhmmm~” Came the rumbles of the sleeping giant. At once, Shiny and I stopped. My heart beat against my chest. Slowly, we felt the ground begin to move—a lurching in our stomachs as the world swayed forward and back. “Mmhmm... oh yes... like that... s-sister...”

I think that if we both weren't so scared and so fucked, Shiny and I might have laughed while we cried. But sure enough, our chamber walked back and before, and below, we could hear Luna's massive ass rolling along the sheets.

More scary than that, though, being a part of a goddess while she moved was how she moved us. We'd since been rocked back from her folds, her vulva pressing on us harder than before, pushing us out from her entrance like the intruders we were.

“Cadence!” Shiny cried. In the distance, the titanic thighs rubbed together, their fast rolling along Luna's slit—blocking any and all light to us. Her vulva clapped together, us snug in the middle, both of us facing the other, his cock still inside me. “We... ugh... won't make it... o-o-out of here.”

“H-Honey?” I said with the next squeeze squeezing the air out from my lungs—and forcing his cock deeper into me. “I-I think... that's the best reason... for us... to have an affair... another mare's...”

“P-Pussy. Yeah. I know.”

I smiled.

“Nnnhh! B-But sister! Noooo~” We both groaned while our goddess moaned. Her thighs rubbed together, harder and faster, squeezing us in the lips of her pussy—almost to the point of breaking. “N-Not down there. We... please... we're in... mhmm... court...”

Shining and I looked to each other, and despite our placement, rolled our eyes. Then, holding each other once more, we began to rock left and right—much to the moans of our inadvertent captor—until we slipped right: falling from her vulva and back to her entrance.

I felt his cock slip out of me during the fall—my face colliding against something soft, wet, and made of flesh. As I rose, there was no stopping from how my rump slid back and forth against the ground, the burning of my pussy demanding to be satisfied at once.

And I wasn't surprised when his hoof came around my neck. Lifting me to my hooves, I saw he was as horny as me. How couldn't we be? All around us, the cave rumbled and mumbled with Luna's moans and words. She herself was rocking herself to some wet dream—a giant brought to horiness by ponies not even an inch tall.

It was amazing what Shiny and I could do together, really.

“Mhmm... d-do it then... sister of mine...” Shiny and I walked forward. Walking past her folds, we both swallowed at the sight: the small hole that led inside the giant mare's pussy. It stopped us. Made us look at each other.

Our doubts, however, were wiped when the world rocked.

Shiny and I stumbled together, huddling close, glancing behind us. Past the folds and the mounds, something round and massive hovered above our prison: Luna's hoof. I swallowed at once, memories replaying.

Was this how it was like for Shiny when he was in my panties? Trapped by my pussy, but also protected by it? Luna's hoof flew toward us, causing the flesh of her vulva to reverberated the impact. Another moan rocked our world.

The edge of her hoof shoved further toward us, pushing the lips of her vulva further away as it came closer toward us. My heart raced from the trouble. Fear played in my mind. All of this... it felt like the mare we were invading had become aware of us, and because of that, was now reaching to take us...

It was all so hot and so scary simultaneously.

But I looked to Shiny. He wore a dedicated expression. We both nodded to the other. Getting trapped by a giant hoof was worse than getting trapped by a giant pussy—we could hide out, fuck, and wait out punishment in the latter.

At least, I hoped that was the case.

So we both moved forward. Shiny took the lead, using his body to push back the folds on our sides. Luna's musk filled the air and inflated our lungs once more. It became thicker the deeper we went.

Not a surprise: we were going to its source.

I paused behind Shiny as he'd come to Luna's opening. He looked at it for a while, then glanced back at me, staring. I nodded. He nodded. After looking back at the opening, he sighed, lowered his head, and climbed forward.

“Aaaaah! Mhmm! Oh, hmm....!” Luna's moans rocked the world inside her pussy left and right, making me stumble in place. Another cry came, not nearly as loud, and when I looked forward, I saw the cause: the walls of Luna's pussy had grabbed Shiny at once—pulling him in with every undulation of her contraction.

It was sexy, in a way, to see Shiny devoured by a pussy. For a moment, I secretly hoped it was my own—having him stuck deeply inside me sounded like such a delight! But that was for another time. Right now, I was wanting to get fucked too.

So I didn't wait around after he'd been sucked in. Whether Luna knew it or not, she had eaten my husband with her pussy, controlling his whole body with only a part of her own. No matter how hard he fought, no matter how much moved around, he was now trapped inside of her.

He was subject to her every whim. Carried around wherever she went, Shiny wouldn't be able to get out by himself. Both of us were about to embark inside of a mare during a wet dream, and to us, this was a dream come real.

I took a few steps along the fleshy surface, coming to a stop before Luna's opening. Standing around for a second, I glanced back, taking one last sight of the world outside and beyond Luna's pussy.

Her hoof covered the top of her slit. The light spilling in below obscured anything past the opening. Right now, I was on Luna, but not in. It was safer to crawl inside her while she touched herself, but still, doing so rendered Luna full control over our bodies and our lives.

Shaking my head, I looked forward again. Going to her opening, I stuck my hooves in—feeling something wet, soft, and warm contract tightly around my forelegs. Giggling, the first tug of her walls pulled me in: finding no from me.

Closing my eyes, I allowed myself to be taken in by another mare's pussy.

I do not know why I awoke, but I did, and while extremely horny.

My eyes opened while my mouth kept on moaning. The world blurred into color and things. I was lying on my back, though it was slightly arched, and my legs were parted to a slightly uncomfortable angle—the unpleasant sensation washed away from the pleasure tingling between my legs.

“Mhhmm? O-Oh!” My head flew back by itself—my eyes sliding closed. My hoof was already at my pussy, flicking up and down my slit, hitting against my clit. I focused on my special spot for but a moment, drawing circles on the bundles of nerves. “What a... mhmm... way to wake up.”

My mind was a cloud: how did I end up like this? I recalled entering the room, seeing my panties, and getting both mad and off to the idea of Cadence and her love fooling around with them. It sparked an itch from my pussy—one that was becoming a rather persistent sensation.

“Why... I never... mmm...” There was something in my pussy: or it felt that way. For a second, it felt like something was rubbing against my walls, scratching at my flesh—everything driving me beyond wild. I didn't care to investigate, I only shoved a hoof in as far as it would go.

And then I enjoyed myself a second time.
