It was a bit early, I even felt the need to protest against heading out to shop for costumes to rent like this, but Geena insisted that we do it today, saying it’s not only better to get it out of the way early, but this way we’ll get all of the best choices for costumes!

We hadn’t exactly decided on a theme yet, and despite my attempts to coax out a hint as to what we were going to go as, Geena kept her lips tightly sealed, either having something in mind, or leaving it as a surprise.

As we arrived at the place Geena had picked out, my eyes widened with just how big it was. I was half-expecting some out of the way specialist store, but this place was more like a compound of costumes. It was practically a warehouse inside, a myriad of sections with several subsections within, every aisle giving way to familiar tropes, as well as a few that sounded unfamiliar.

A clerk comes by and offers their help, smiling at us and asking whether we were looking for a matching theme for our outfits.

“That’s quite alright! We’re going to be looking for a little while.”

The clerk nods before giving a few tips of traversing the area as to ensure we don’t get lost, then leaves us to our daunting task of picking out only two outfits from this warehouse. Now on our own, staring down the building that gives way to a seemingly endless array of aisles, Geena turns to me and smiles before grabbing my hand, leading me along as she begins our search.

Things are beginning rather slowly, Geena stopping at almost every outfit, pulling it from the hanger and placing it against me, sizing it up and looking from a few different viewpoints before shaking her head, putting it back and guiding me to the next area she’s taken interest in. It really was like a kid in a candy store, she was overwhelmed with the endless choices and was struggling to settle on one.

Geena notices me staring and stops, an innocent smile on her face as she questions what I’m looking at her so intently about.

“Nothing. It’s just kinda cute how enthusiastic you are about this.”

Geena blushes slightly before pulling me closer to her, giving me a chaste kiss before breaking our embrace.

“Come on, Casanova. Let’s keep looking~”

We soon get lost trying on a wide array of costumes together, Geena had me try on a fireman’s outfit first of all, tracing her fingers across my body as she whispered.

“I certainly would love to see you slide down my pole~”

A trembling arousal runs across my body, bringing a giggle from Geena’s lips before we can that idea, placing it back in the protective sleeve before making our way back to the aisles to search for more.

“Ooh! How about this?”

I dart over to one of the racks that held comedic costumes, reaching in to grab a set. I present them rather proudly to Geena, who scoffs at the notion.

“What’s wrong? I dress up as the hammer, and you’re the nail! Isn’t it kinda cute?”

She grabs my collar and forces me closer to her again, delving her tongue past my lips and practically down my throat before breaking it, leaving me breathless as I stand there awkwardly with the costumes.

“It’s a little cute, but you have the outfits mixed up~”

Her taunts are well-received, understanding that to be honest, yeah I may have gotten them twisted in my head in hindsight. With that idea scrapped, we continue and after more time spent looking, I notice Geena’s eyes glance over at a specific section.

Dresses

She pauses for a moment, something clearly running through her head, then changes direction and I’m dragged along on her little adventure.

The sheer number of subsections in this aisle were mind-boggling. There were princess sections, dresses from famous events and stories, movies, popular television shows, anything you could think of!

Geena suddenly stops at one of the sections, the sign above letting her know that all kinds of old fables and stories could be found here. It didn’t take her long, clearly having it in mind as she wordlessly sifted through the racks before pulling out the outfit.

“Ta-da!”

In her hands, as she performed an over-the-top display, was an outfit similar to red riding hood, with a mention for the basket being available on purchase to sweeten the deal.

“What, does that make me the big bad wolf then? I hear those things are pretty hot, I’m not so sure…”

My idea couldn’t have been more wrong, as Geena soon put me in my place.

“If anything, I’m the one that’s going to be big and bad.”

She then shoves the hanger into my hands, bringing her face close to mine as she smiles sadistically.

“And yes, it’s going to be very hot~!”

I didn’t have much more say in the matter, Geena guiding me away to the changing rooms to begin my ‘transformation’.

Once pushed inside, I could only hear Geena’s faint giggling as I hung up the outfit on one of the hooks, unzipping the clear plastic to feel it between my fingers. The fabric was soft and delicate, but not fragile, very pleasant to the touch as I began pulling it out of its protective sleeve. I began sliding on the outfit piece by piece, first stripping down my own clothes, realizing awkwardly that the outfit came with a pair of panties, meaning that I would be completely wearing the little getup.

Reluctantly I obey Geena’s guidance, sliding off my underwear and slowly tracing the red panties up my legs, feeling it snugly hug my cock and snap back against my ass. With the worst part out of the way, feeling emasculated already, I don’t have many reservations left to hold as I slip on the white stockings and shoes before pulling the skirt up my body as well, feeling the frilly lace brush against my skin, bringing a shiver down my spine as I deal with both the unfamiliar sensation and the fact that my cock was beginning to stiffen beneath my skirt, hidden away.

Now fully dressed in the costume, I take a few glances at myself in the mirror, turning around to admire how it looks on my figure, seeing how the skirt flows naturally and it hugs my body tightly.

“Are you finished yet?”

Geena’s voice snaps me out of my little thoughts, reminding me that I’m expected to put on a show for her in this. The image of that is embarrassing enough, but Geena is certain to not let me off easily from this, she’s definitely looking to dig this deep, and as she calls for me one more time, I don’t exactly have much of a choice than to come out.

It was humiliating being brought out like this, but I had already slipped the outfit on, and certainly didn’t want Geena to come inside. This way, at least I could hold onto the knowledge that all she could do was admire me, but inside the confines of the dressing room, there would be nothing holding her back from opening up her black bag and giving way to a very intense trial of the outfit.

Stepping past the curtains, I screwed my eyes shut for a moment before meeting her gaze, seeing her smug grin as she savoured the sight of me looking embarrassed in her choice of dress.

“You look so cute~!”

Her words didn’t help how I felt, sending a shiver of shame down my spine as I stood there, red-faced and waiting for her permission to change out. Only I was left there, standing in an awkward silence as Geena continued gazing across my body, how the stockings clung to my legs, peering her head down to try and steal a glance under my skirt. Instinctively I press it against my body to stop her seeing underneath, then realize what she had unintentionally made me do, acting as if I actually was some shy girl hiding her shame.

The only shame I had to hide was the growing bulge beneath the panties, hiding out of sight under my skirt, I could feel it tensing with every smirk Geena flashed at me. Whilst I’m struggling with my embarrassment, I didn’t notice Geena standing up from her seat, flinching as I see her step closer to me, wondering what she was planning. That’s when I saw what was in her hand, a familiar black strap dangling from her grip, my breath is caught in my throat as I understand what she’s intending to do with it, and the bulge in my panties grows even more desperate than before.

“You look really cute in that dress, Mike~”

Her words were absolutely dripping with lust, her breath had become closer to panting as she fumbled with the straps around her waist, and I reside myself to placing my hands against the wall of the changing room. After hearing the final strap securely tightened around her waist, a perverse shiver coursed through my body, made even worse as Geena leaned over my shoulder, pressing her breasts into my back as she let the strapon teased between my legs.

“Now that you’re dressed like a girl, how about I make you squeal like one~?”

I let out an involuntary gasp as she pulls my panties up my body, cushioning my cock in the fabric painfully before pulling them down, listening to her giggles by my ear as she savours the sight of my trembling.

Her hands run down my chest, greedily squeezing at me before sliding between my legs, grabbing at my now painfully-hard cock, squeezing it tightly.

“Oh? What do we have here?”

I can practically hear the glee in her voice at having realized how much I was trying to hide my own enjoyment, the revelation giving way to the possibilities of pushing this much further. After finding out my little secret, Geena wastes no time in pressing her strapon between my cheeks, grinding the tip against my quivering hole for a moment before sinking it in, pushing her hips forward just enough for her to slowly press into my ass.

My legs quiver at her advance, a subtle reminder of what my situation was as my cock began smearing the front of my skirt with precum as she pushed deeper. After a few painful, yet pleasurable moments, I feel Geena suddenly smack against my skin, having bottomed out her strapon inside of me, giving her the chance to giggle into my ear, the vibrations causing me to shiver beneath her control.

Each movement caused my body to cave more and more to her advances, I could feel my ass loosening up at her constant probing, giving way to a more rhythmic pounding of her skin against more, filling the changing room with the sounds of Geena fucking my ass. I couldn’t deny that the sheer amount of pleasure being forced upon me was overwhelming, and before I knew how far my depravity had taken me, I felt my cock begin to tense up, threatening to stain the wall of the changing room at any minute.

Whilst lost in my throes of passion, Geena snapped me out with her teasing words, whispering into my ear as her pounding slowed down, dragging out my arousal even further than before.

“Is someone getting a little ahead of themselves?”

It made my heart sink, already Geena had noticed my body writhing between her and the changing room wall, understanding how completely I had given in to the feeling of being fucked in the frilly outfit. The way it clung to my skin, the stockings hugging my thighs, the panties around my ankles, even the skirt brushing up against my cock as Geena slammed into me.

All of this reached its pique as Geena decided enough was enough, before anyone became the wiser, she increased her pace again, practically fucking me into the wall as my lips gave way to my own squealing, overwhelmed completely by the pleasure forced upon me so suddenly.

“I told you I’d make you squeal~”

Blushing over my own outbursts, it only made the following sensation even more intense. With Geena giving me little chance to compose myself, I can feel my own orgasm crashing over my mind quickly, my eyes rolling up as my legs buckle. She pins me up against the wall to stop me from crumbling, holding me there as I audibly whimper, squirting my load across the underside of my skirt as she gently grinds the tip of the strapon inside of my ass.

“That’s it… make a big mess for me!”

It felt like my orgasm would never end, riding out the constant pleasure Geena brought onto me as I spasmed in her grip, until finally my arousal began to melt away, replaced by the burning humiliation in having succumbed to her advances so easily, as well as the fact that this all had just happened in a public changing room!

As my half-limp body slumps to the floor, Geena having let go of me, I hazily manage to make out her orders.

“Clean up your mess and strip down. We’ll have to let reception know we’ll pay for the damages.”

Her tone seems cold at first, but I can hear the hidden lust within her words, her voice trembling slightly after our little scene together, clearly enjoying not only the sight, but the fact that we had the chance to indulge in something so perverse.

With my legs still shaking, I clumsily strip myself down in front of Geena on her orders, my face flushing red under her watchful gaze as she takes in the sight of the fabrics sliding down my skin. With the stained outfit placed back in its plastic sleeve and on the hanger, Geena heads to pay for the damages whilst I try to recover my senses.

She’s not gone long, coming back rather promptly and pulls me from behind the curtain, circling her arm around my waist as she continues guiding me throughout the store as if nothing happened. It’s only a few steps before she leans in by my ear, whispering gently as I tremble at her words.

“Let’s keep looking~”
