Size Erotica: Woman, in Ecstasy, Chapter 5

“Woman, in Ecstasy” follows the story of a woman on a date with her boyfriend at a museum of sex. He convinces her to volunteer as part of a kinky art installation, where she grows, shrinks, and becomes a horny slut at the mercy of strangers—one of whom has eyes on her boyfriend. Read Chapter 1, Chapter 2, Chapter 3, and Chapter 4.

In this final chapter, Lisa gives Noelle a gift before taking her new toy on the kinkiest ride of her life.

I’ve unveiled this story in five chapters, each one lewder than the last. I’m proud to be able to offer author-read audio for each installment. This is a way to ensure increased accessibility for members of the kink community who use screen readers, and adds some extra sexiness for my fellow audiophiles. All told for this series, I’ve recorded 105 minutes, or about 1.75 hours of free erotic audio!

Topic & timing

If you want to know why I’ve written a story about a woman losing her agency, and why the hell a self-respecting feminist would choose this particular moment to release it, I answer those questions and more in a kinky blog post: Embracing My Inner Size SlutTopics include a discussion of agency, bodily autonomy; nonconsensual themes in size play, hypnosis, mind control and bimbofication; mentions of trauma and sexual assault, and resources for survivors.

We really need to take care of each other and ourselves right now. Be gentle with yourself. Set boundaries. Figure out how your body in particular asks you for different kinds of rest, like mental downtime or peace and quiet. The most important thing is to listen to your body and decide what’s right for you. Maybe that’s reading/listening to this story today. Maybe it’s waiting for a day when you have more energy or fewer responsibilities. (Or when you’re just really horny!) After all, no matter how much we fantasize otherwise, you’re the only one who can decide what’s right for you.


Artwork & shout-outs

I’m thrilled and deeply grateful to @pseudo_size for creating this GORGEOUS and sexy render art of one of my favorite moments in the story.

Render art by @pseudo_size of a giantess growing inside a glass room in a museum, while two smaller people look on from outside. A man stands at the controls, and a woman holds a towel closed while smirking down at the giantess, who looks very aroused and has her hand up as if begging. Her breasts are expanding at enormous sizes.

It’s no exaggeration to say that this story would not be what it is without pseudo and his help. His skill and empathy in beta reading, his insight into character development, story arcs, strengths and vulnerabilities, all of it helped me tell the story I was trying to tell.

Please go check out his art and writing, including a new story he began sharing for Pride Month, Holding Space. He’s released the final chapter and it’s one of the sexiest stories I’ve ever read in the size kink community.


Story inspirations

Inspiration for this story comes partly from a place that’s been on my bucket list for years, The Vagina Museum. It’s hardly the only museum of sex, but it is the world’s first bricks-and-mortar museum “dedicated to the gynaecological anatomy.” Learn how to support their work in my introduction to Chapter 1 (and discover why I’ve chosen to depict nonprofits in this way).


Support the author

Money is tight right now. I have twelve works of fiction in progress, ranging from wholesome to kinky as fuck. I’d like to continue releasing them here for free.

If you enjoy this story and want to see/hear more like it, the best way to do that is to support me financially. (The second best way is to boost the signal on my stories and encourage your friends to support me, too.) Thanks, y’all!

A note on the hypnosis: seriously, I DO NOT recommend driving while listening. I don’t know if it will be as powerful for you as it has been for me, but I literally put myself into a subspace trance multiple times while writing and editing—and I’m honestly not sure what will happen as I read this aloud for you. Either way, I suspect we’ll both have fun~


Read the story

AUDIO VERSION: Listen to a 24-minute author-read version of the story here. Do not listen while driving.

NOTE ABOUT THE AUDIO: please be gentle with me! This is a very enthusiastic reading, but an imperfect one. Turns out, reading smut where I force a character to get so turned on she loses her words… has an interesting effect on my ability to read her part.

I had limited time to read this chapter in a single take, and while I did my best in Audacity to edit my worst stumbles in the sound clip, there were several others I left in. And some of the edits sound like, well, edits. I’m not going to let perfection impede the publication of this story any longer. Consider it added realism for Noelle’s descent into sluthood!

You may notice the audio quality itself improved this time. Thanks to @Giant_Micro for his tips on DIY pop filters. If you’d like to help me buy a bonafide mic and a pop filter to make the sound quality better for future recordings, or if you’d like to help me pay for audio engineering from a community member with experience, I’d welcome donations of any size.

Lisa stepped inside the exhibit, looking very different from the woman who had staggered out of it at the start of the day. She stood still for a long moment just inside the door, closing her eyes and throwing her head back, drawing in a deep breath.

She smiled when she opened her eyes again. Then she stepped close to me, very very tall, with one hand braced on her hip. She looked so big to me that I could only see her face through the opening between her tits. It felt good to be so small with her that even her belly button seemed too high for me to touch.

She stroked a hand down her lips, throat, and down between her breasts. I tried to stretch my arm out and touch her thigh, but she was just beyond my reach. She trailed her fingertips lower over her stomach and then moved her hand, big and warm, and pet the top of my head. I almost purred, nudging my head against her.

She used a single huge fingertip to stroke me the way she’d touched herself. Lips, throat, breasts, stomach. Then my soft bush, sending a thrill through my body and a moan out of my mouth.

“Hello, toy,” she said. Her voice turned me on. That word… I liked that word a lot. “What do you think of all this?”

“I just want to cum,” I begged. Words were harder to find but easier to say, like I wasn’t fighting it anymore. Or maybe, it just didn’t bother me as much when I looked inside and didn’t find the right ones. “I can’t fuck on the machine, I’m too small.”

She smirked down at me. “Mm hmm. Glad to see you’re back to living in the moment. You know, you’re about to have an experience I’ve craved for ages, so you better enjoy it.” She bent over me, bigger than a building, her hair draping soft over her shoulder like a tall red curtain. I shivered as she drew a finger around each of my breasts.

“Promise you’ll enjoy it? For me?”


She rewarded me by pinching one of my nipples. I moaned. “Um,” I said, trying to focus. “If you wanted to have this…” I couldn’t remember exactly what she had said. “If you wanted to feel this, like you always wanted to… We could trade places.”

She laughed, the loudest laugh I had heard from her yet. “Always giving it up for someone else, aren’t you? You need to learn to take some for yourself when you can. That’s what I’m in a position to do for myself, at last. Maybe it’ll be a good lesson for you. Now. Hush.”

Lisa pressed her pinkie finger to my mouth and pushed inside. It felt a lot like sucking a cock. I slid my mouth over her, riding a giddy rush of happiness at the chance to finally pleasure her. To just feel any part of her inside me was good, but with the dildo filling me up already, sucking her finger into my mouth as deep as I could felt even better.

So full! So good and full and horny.

“Oh, yes. You are an eager little slut, aren’t you? Eager little toy slut.” She mimicked a cocksucking motion and I sucked harder, trying to take her pinkie deeper. She cupped her other gigantic hand behind my head, stroking my hair, guiding me back and forth to take her up to her knuckle, then deeper. “Good job, toy. I’m proud of you.” I melted at her words, a warm glow filling me up even as she pulled out.

She trailed her wet finger down to my clit. Just her pinkie finger was big and thick and so much longer than a cock!

She bent lower until one of her breasts swung into me. Soft and huge, it was like a pillow bigger than a bed. Except this pillow was dotted with beautiful pale freckles.

I was lost in the feeling of her. So close, so close, her skin was just amazingly soft, and she was so big and beautiful and this dildo filled me so completely, I was so close to cumming—

“You’re in a highly suggestible state right now, so I’ve decided that, to better enjoy my experience, I’m going to give you a gift,” she said. “Do you want my gift?”

I nodded, willing to do and say anything at that moment. Close, close, so fucking close!

“Your purpose,” she said. Her enormous lips brushed against my ear and the side of my head. The tip of her massive tongue licked me and I nearly lost my mind. Her voice continued, velvety and impossible to deny. “Your purpose is pleasure.” She paused to lick me and I shuddered, moaning, lost in the feel of her slippery wet tongue sliding down my neck and shoulder, over my breasts. “Repeat it.”

“My p-purp-purpose… plea…” I gasped for air. Her mouth was close, her breath all around me, her words so hot I wanted to melt into them.

“Say it, toy.”

I squeezed my eyes shut and grabbed desperately for the words. “My. Purpose.” I swayed on the dildo, my hips thrusting almost on their own. “My purpose is pleasure!”

“Yes, very very good.” She leaned lower and pulled one of my feet into her mouth. I cried out, speechless with the painfully good, overwhelmingly soft sensation.

Too soon, she let my foot slip out of her mouth. “Your purpose is to come as often as you possibly can.”

The sentence was so long I almost wanted to cry. But I’d do anything, anything for her. As long as she touched me again!

“My purpose,” I panted. “Is. To cum. As often. As. I. Can.”

“YES.” She looked me in the eye, maybe for the first time since entering the exhibit, and it was hard to tell because of her size and the angle, but to me it read like a look of pride. She licked me from my shivering foot, up my leg and thigh, over my clit—“OH GOD,” I whispered—up my stomach, up over my breasts as I moaned, then—

Then she kissed me. Her lips overpowered my face, a softness like her breasts but more sensual, more intimate. I melted.

She moved away, then wrapped her hand fully around my body. She lifted as my eyes widened. Pulling me bodily up and up, oh holy fuck

As I crested the top of the shaft, I looked down at the beautiful, glistening, truly absurd long length that had been shoved deep inside me all this time. It made me dizzy the way the first hill on a roller-coaster feels dizzy. High up. No way to back out. The promise of a thrill just seconds away. And it made me ache with a fear I might never be full again.

She held me in place, trapped in her hand, my pussy barely containing the round head of the dildo. “In return, you’re going to give me a gift, too. I want your first orgasm, toy. Understand?” I looked up at her, nodding, almost sobbing with relief.

She pushed me down, a roller-coaster in slow motion, exquisitely slow but no less exhilarating.

Filling me. Putting me back where she wanted me. Where I belonged.

I howled, and came for her. A beautiful agony of clenching and thrusting, and my climax finally, finally crashed through me.

“What a good toy.”

Wide-eyed, my mouth open with awe, I hung on the dildo where she’d pushed me. Back in place, almost relieved to be trapped once again. I had barely approached a sense of afterglow when she moved, her mouth and tongue and breasts pulling far out of reach. “Wait! Please don’t go!” I writhed, twitching on the dildo, making pathetic sounds.

To my relief, she didn’t stay away for long. She loomed over me again, her smooth thighs huge and strong above me. Her beautiful pussy. I couldn’t remember much, but I remembered that the first time I had seen her pussy, I had turned on the Fucking Machine and fucked her with it.

And now, as I looked up and up, her red, wet folds above me lowering down and down, the musk of her scent, the heat of her body, the way she brought me so, so close… I got it. I knew what her fantasy had been.

“Think you can control me?” She growled under her breath. With one hand, she used two fingers to push open the folds around her opening. I didn’t know what her words meant, but my body knew what her pussy meant. I moaned, so turned on I felt lightheaded.

“Daniel,” she called to the man outside the glass. “Turn on the Fucking Machine, would you? And fuck me with your girlfriend.”

I gasped. Not with shock, but with intense desire. I wanted this. I wanted her. To be in her. Just like I wanted from the start, to become just like her.

Did he even hesitate?

He plunged me right into her. Through the thick heavy folds, into the wet heat and pressure pushing on me from all sides. The machine rocketed me in and out, shoving me through her slick opening. I moaned and screamed inside her, a living dildo.

I came. Nobody noticed.

My helplessness only turned me on more. Helpless and small and deep inside. Being fucked while fucking her, fucking her, fucking her. I came again, and a third time, as her body clenched down tightly, trapping me even more completely, but my joy carried me into a new place in my mind, one without fears or shyness. No classes or contracts or boundaries or jealousy. Not even any confusion. Only pleasure, and a powerful joy without words. As she released me, a fourth orgasm drilled through me, almost as if it was the only thing I knew how to do anymore.

I took a hungry, gasping breath as she lifted off me. Her moans hummed through the air as she pushed me, not back inside, but through the layers of her full, puffy lips. She had changed the angle and let the thrusting of the machine work me back and forth against her vulva and big, swollen clit. I shouted into her body as another climax made me shiver, and lost count as I joined her in another. Her thighs closed around me, a different kind of skin on skin than it had been when I was inside her. I heard her call out, and breathed a sigh of relief as the Fucking Machine finally, finally stopped.

But still, she wanted more. I knew how she felt. She ground against me, moving until my face positioned over her thick clit. “Suck me, slut,” she growled. “You’re my pleasure toy and you’re going to give me what I want. Make. Me. Cum.”

I fit my eager lips over her clit like I had her pinkie, sucking it into my mouth, licking as fast as my tongue could go. Her scent filled each breath I took. The coarse red curls around her vulva tickled my arms as I braced against her sticky hot skin.

I felt powerful and full of purpose as she cried out, her scream loud all around me, her body fucking and shaking against me. Then a new wave of sound hit me. She was screaming again, dear God, how many times had she cum? Still she clung to me, and used me, and took me inside again, fucking herself with my entire body, and it was like music when she moaned and I moaned inside her, cumming again in one long orgasm to match her own.

I slid outside of her. I rested against her soft gigantic thigh, a toy put to the side by its owner after it had been useful. Panting in the heavy humid air full of her scent. Waiting. Grateful.

One more half-orgasm rippled through me as she wrapped her hand around my middle again and freed me completely from the dildo where I had been trapped. Without the feeling of fullness, without the roller-coaster in and out, up and down, I hardly knew where or who I was. Could I still be a slut if I wasn’t being fucked? “Can I still be a toy?” I asked, drunk with sparkly afterglow.

Lisa laughed, and hugged my sticky body between her big, freckled breasts. “Sure thing, doll. You look so cute when you’ve been used hard.” She sighed, and the sound of her breath surrounded me. “Damn, but I really lucked out that you were the one to sign that contract. You’re gonna do just fine, here.”

“I’m a good toy?”

“Better than I ever was.” She petted my head and ran her fingertips through my wet hair. I nuzzled against her, sighing happily. Good toy, best toy. Yes. I gave a satisfied wiggle.

She lifted me in her big, soft hands and looked me over, amused. “I’m going to miss that easy, happy feeling. But I need to get the fuck out of here before anyone touches those levers and traps me in here with you. I’m sure if Kal knew I was in here with you, he’d jizz his pants at the thought of the fundraiser he could plan.”

She gave me a big, tender kiss on the cheek then looked up around the space. “Thanks for helping me say goodbye to this place. I think I’m going to tell him you want to stay here and be small for a while. Sleep it off, you know. Maybe he’ll even believe me.”

“Who?” I said, grinning up at her. I was barely hearing her words, instead looking at her lips, and imagining how good it would feel for her to kiss me between my legs.

“My new boyfriend,” she said. She tilted her head at the door beyond, where a huge handsome man was leaning his head against the glass. His pants were undone, his cock in hand. White cum dripped down the glass, and I could see he was breathing hard. He shared a look with Lisa, who crooked an eyebrow at him.

“Imagine how many orgasms you’re going to give him, just from his knowledge that you’re here. Safe behind glass. That you’ve become a living embodiment of his fantasy, no needs of your own except pleasure, unchanging except to suit sexual curiosity. While I help him reach those orgasms, and finally get some human fucking contact again.” She looked distant for a moment, then shook her head as if coming out of a daze. “Sorry, doll. I hope you can forgive me someday. Maybe you’ll handle this better than I have.”

“You can handle me any time you like,” I said, giving her my flirtiest smile in an attempt to reassure her. She had said a lot of words, and it would take me a long time to think about them. “And your boyfriend too,” I added, to be nice.

She laughed. “Don’t worry your pretty little head about it.”

I nodded, and began stroking myself. The pleasure came so much easier now. I could feel another orgasm approaching. “I don’t want you to go. Come back and play with me, soon?”

She grinned wistfully. Then she stroked me. Kissed me between my legs. Just the pressure of her lips once over my vulva was enough to send a climax rushing through me. I trembled in her palm and kissed the pretty freckles on her cheek in thanks.

She smiled, licking her lips clean, and lay me gently down in something soft and blue and white. The cup of my bra.

Then she stood up, and up, and up. She was so tall, but that made sense. From a toy’s perspective, everyone would look tall.

She quirked an eyebrow. “Guess we’ll find out, won’t we?”
