Context: This is a short story written for Day 5 of Kinktober 2025 using the prompt words Pin-up / Pinned.

I approached a group of girls chatting enthusiastically in the sorority house lobby. I didn’t quite share their bubbly excitement. My perspective was closer to dread. I tapped the shoulder one girl in particular, the sorority president.

“Hey Emily. Mind if I have a quick word?”

“Oh hey Nina. Sure. You’re going to make it to the calendar planning meeting this afternoon right?”

The ‘Girls of Sigma Upsilon Beta’ calendar was an annual event. Twelve attractive sorority sisters in cute costumes, snapped by a professional photographer, one for each month. It was always a very popular item on campus, ending up hanging on most male students’ dorm room walls.

Rumour had it that the photographer Emily hired this year had past experience of directing porn, leading to expectations of a racier set of pics than usual.

“The calendar thing is actually what I wanted to talk to you about. I know you said I should do it, but I’ve been thinking. I’m flattered at the encouragement and all, but I’m not really sure I'm the right--”

“Gonna stop you right there Nina. I wasn’t asking you to participate, I was telling. As if we’re gonna exclude our blonde bombshell! There’s probably a lot of people expecting and looking forward to seeing you in it. Besides, after that snafu at the last fundraiser, you owe me.”

I shuddered, rubbing my backside at just the memory. 

“Look just come to the meeting. We’ll be deciding then which girl does what month. You can make your case for whatever you’d prefer and feel most comfortable with.”

“I guess that helps...”

“Good! See you then.”

Emily left to continue preparations, giving me an encouraging butt pat on the way. I sighed. At least I’d have some opportunity to control what I’d be wearing. Some.

Shortly before the meeting, I was heavily engrossed in my phone, browsing pictures of beautiful professional models online. I’d forgotten why I started.

Someone cleared their throat to grab my attention. I looked up to see two of my fellow sorority sisters. Brooke the buxom brunette, one of the hottest girls the sorority, plus one of her usual lackeys.

“Hey Nina. Or should I say fellow pin-up girl~. Looking up photoshoot ideas?”

“Errr... yeah. That’s what I was doing...”

“Emily wanted us to find you. We’re doing some costume testing in advance of the planning meeting. Taking a few quick pics to get a better idea of what works best on who.”

That might work to my advantage. I could find something with more coverage and make sure it looks good.

“That’s a good idea."

“Mhm. Follow us.”

We headed upstairs and into one of the house’s large general-purpose rooms. It was filled up with racks and racks of outfits. I perused the options. There were so many, plenty that I’d actually be perfectly content to model.

“Nina, over here. We have one Emily wanted you to try out.”

Brooke approached with a white full-length tube dress for me. I could see myself potentially settling on that.

“Alright, strip down.”

“What?”

“Strip to your underwear. You’re obviously not going to be able to wear this over that sweater and skirt.”

“Is there somewhere more private I can...”

“Come on, we’re all girls here.”

She wasn’t wrong. I reluctantly removed my clothing until I was down to only my pink bra and panties. Brooke smirked at the sight and stepped closer, ready to help me into the dress. She lifted the base up, and I raised my arms towards it.

“Arms by your sides please. It’ll be easier to feed them through.”

“Uhhh okay. Though I don’t see how that could make it easier...”

Brooke ignored me as she and her friend pulled the tube dress down over my head. Down around my shoulders, waist, hips, legs. It was an awfully tight fit, especially against my arms, pinning them against my body. My legs barely had any room to move around as well. The two girls tugged it all the way down to my ankles, until eventually my head popped out of the top.

“Uhm. Where are the holes for my arms? I... ngh! I can’t move them up.”

“Really? How odd. Better keep trying then~”

“This is definitely way too small for me. Ugh! Seriously Brooke, I think I’m stuck.”

“Hold on, there’s more to add.”

She grabbed a pair of dark pantyhose.

“Huh? What do you expect to do with those? I’m hardly going to be able to put on pantyhose now, after I’ve already been squeezed into this stupid tight dreMMPH?!”

“Don’t worry about that. We can still add these.”

Brooke had quickly balled up the pantyhose and before I saw it coming, forced the bundle straight into my mouth. She held the back of my head still while she jammed it all inside. I wriggled inside the dress, but couldn’t stop her.

She brandished a neckerchief next, wrapping and cinching it around my head. It constricted tight enough to pull inside my open mouth, dragging the pantyhose gag in even further.

“Oops I tied this on a little high. You can pull it down to your neck yourself!”

“HHMMGHH!”

“Do you like the pantyhose? We each wore that pair for a while earlier. Now it’s your turn to ‘enjoy’ it~”

The other girl spoke behind me.

“Perhaps a trendy belt to complete the look?”

“Ooh that’d be perfect. Hand it here. So Nina, should I put it on here?”

Brooke knelt before me, holding the belt loosely around my ankles.

“Nnngh!”

She strapped it on, drawing my feet together.

“Too low? I just can’t get things quite right today can I? Hand me another one.”

“Mmph?”

Brooke proceeded to add three more belts: above my knees, around my waist and wrists, and just below my breasts. I was furious. The prospect of having to squirm out of the dress without help was bad enough. Escaping while belt-bound as well didn’t seem possible.

“Not bad. Not bad at all. But maybe you should check what's in the back room too.”

She gave me a hard shove and forced me to hop.

“Mmmh!”

She stepped after me and pushed again. I bounced my way to the corner of the room, where there was a door into a small closet. While it wasn’t my top concern, I felt a flash of annoyance learning that there was somewhere I could have changed in private the whole time!

“In you go... Now you have a look around and see if there’s anything in here you’d prefer to try.”

“Mmmh?”

Brooke almost pushed me over as I was forced forward into the closet.

Slam!

The space suddenly went pitch black. Brooke had shut the door on me!

click!

And locked it?! I shuffled frantically back to the door, moving a bit too fast and banging my head on it.

“Hhhmmh!”

“Take your time in there Nina. We’ll be back to let you out later.”

“MMMPH?”

I heard the two girls walking away giggling. After a few seconds, I heard another distant loud click. They locked the main room’s door as well?

I thrashed within the tight dress and belts, yelling as loud as I could through the big wad of pantyhose stuffing my mouth. I knocked my shoulder against the door as hard as I could, hoping someone could hear.

Heavily gagged, in a locked closet, in a locked room... no-one was going to hear.

“For July I was thinking a beach bikini for a cute summer sort of vibe...”

Emily sighed. The girls sitting around the meeting room table watched her rub her temple in frustration.

“... I was going to ask Nina to take this one. I can’t believe she didn’t show up for this meeting.”

One hand shot up into the air. Brooke’s hand.

“Ooh, I’d love to take that one Emily. I look really good in a bikini~”

“I don’t doubt it. Any objections? Okay, putting down Brooke as Miss July. Hmm. Where am I supposed to put our absentee then?”

Brooke interjected again. “About that, I actually had an idea for her. So you know that photographer you’ve hired...”

The sorority girls crowded forward near the edge of the set, trying to get a closer look. They were dressed in a variety of flattering eye-catching outfits. Miss April in a leotard and bunny ears holding a basket of eggs. Miss March in a green leprechaun-style buttoned jacket and top hat. Miss June in a floral summer dress. Miss December in a sexy ‘Mrs Santa’ two-piece.

I was so jealous of every one of them.

“Alright Miss February. Give me your best come-to-bed eyes.”

“Wait wait! There’s a slight wardrobe malfunction. As daring as this concept is, I don’t think a nip slip would be allowed.”

Emily hurried over to me, herself dressed in a sequin dress and ‘Happy New Year’ sash for her Miss January role. I was laying on a plush velvet rug surrounded by large soft cushions. Emily adjusted the tiny piece of fabric that served as my bra back into position.

“There we go.”

“Mmmhh!”

My February outfit was the smallest of all twelve by a large margin. The bra and panties were little more than thin red string with three small red hearts covering my nipples and crotch. As deeply degrading as that was, it was the accoutrements that bothered me.

My ankles and wrists were both bound securely with bright red rope, plenty more ropes surrounded my torso and breasts in an intricate shibari arrangement, and my mouth was filled by a large ballgag with a large bow clipped onto a small ring on its front.

“Now let’s remember Miss February, you’re offering yourself up as a helpless sexual object to be ‘unwrapped’ and enjoyed by your lover as a Valentine’s Day gift. The camera is your lover. Seduce it!”

flash! flash! flash!

Rather than obeying the instruction, I sat still, fuming and glaring at the camera. It turned out the photographer had some history with rigging and shooting bondage as well. His expertise with ropes had me tied up far tighter than necessary. Why couldn’t I just hold my hands behind my back myself? And the huge ballgag was barely even visible behind the bow!

Emily groaned. “Do you think this little protest is going to change anything Nina? The longer you refuse to co-operate, the longer you’ll stay tied up. We can wait. Maybe even add a few more ropes.”

I grumbled with disdain. Reluctantly, I looked straight into the lens and gave it a drooped-eyelid suggestive look.

“That’s more like it. More. You want to be touched sooo badly right now. The viewer is the most important person in your world. You’ll do absolutely anything for them. Atta girl. Chest forward. Come on, really show yourself off!”

I hoped that the heavy blushing on my face wouldn’t show up in the final print. I prayed for the process to end soon, debasing myself as I tried to be sexy in front of eleven women, one man, and ultimately, hundreds of colleagues and strangers.

“Turn around and lay on your front please. Let’s get some shots of that curvy backside. Arch your hips up please. Higher. Higher! Perfect. Hold that pose...”

flash! flash! flash!

In the back, Emily and Brooke stared in awe.

“Brooke, you are a genius. This is going to be our best-seller ever. It’s a shame February is the shortest month! I don’t know how we’re going to pick which picture to use.”

“We need a second February-only special edition calendar~”

“... Okay I know you're kidding, but yes, yes we do. I am so going to make that happen. Oh hold that thought. Pause! Miss February’s top fell off again!”

“Mmmph!!”
