Get a group shot (only cosplay changes)

Feeling a bit impatient to discover the answers to your questions, you raise your camera and lean back to fit everyone in the front of the room into the same shot.

Samantha is answering a question as you click, and almost immediately you can hear her voice become more breathy and alluring. The rest of the room doesn't seem to mind. You head back to sit down next to Becky, who smiles as you sit.

When you look up the changes are obvious.

Brad is now looking very fit in a costume that is much better, though even as you watch you see the tip of his lengthening and hardening penis rising from behind his pants, no longer fitting.

Samantha's costume has shrunk into a super-heroine-style bikini that holds the same colors as her original costume, but her bikini top is now hefting some medium boobs on the previously-flat-chested girl. You can't see below her belly button from your current vantage point, but as you leer at her she takes one hand and moves it down to obviously begin feeling herself up.

Jenny's maid costume has shrunk into a skimpy French style, her now immense tits resting in the cups that can barely hold them. Her tail is now smaller and sleeker, though, you notice, it still appears to be a prop.

And finally, the centaur, Olivia, is completely bare-chested, with her braid running between her two tear-drop breasts. They're bigger than before, but a bit saggy, the way some guys like them, and they sway as she adjusts her now micro-skirt. The back end is, unfortunately, still much the same as it was. The legs are possibly a bit more shapely, but they can't compare to her actual legs, which now each sport a long sock that rises to her calves. You can just see her sexy red underwear as she adjusts her skirt.

Becky raises her hand, and Brad points to her. "Yes, and what question do you have, sexy babe?" he asks, and for such a corny line he makes it sound pretty cool. He begins absently stroking the top of his long penis as Becky stands up.

"I have a question on the construction of the rear of the centaur," she says, eyeing his penis hungrily but otherwise not really seeming to notice the changes. "How does it attach?"

Olivia nods and pulls up her skirt slightly, revealing the underwear has now become a thong, as she unhooks the belt-like mechanism from her waist. The movement sends her teats swinging, and you see Brad stand up and begin to walk over.

Olivia moves the apparatus over next to the table, grabs the microskirt still up on her belly, and removes it to the floor, now fully nude apart from her sneakers. She begins pointing to pieces of her costume and explaining them as Brad steps up behind her and grasps both of her tits in his hands and begins to knead them like warm dough. Her breath catches slightly, but she continues discussing how she constructed her prop.

Samantha, meanwhile, has begun to kiss Jenny passionately. She pulls down the front of Jenny's maid outfit, revealing Jenny's full breasts to view. They're obviously fake, but it's well-done, and they stand proud and firm from her chest as she sighs, returning Samantha's kiss.

Olivia is wrapping up her answer when Brad abruptly grabs her by the waist, lifts her up into the air slightly, then lowers her so that his dick slides neatly into her now-naked pussy. You're not sure where the thong went, but it either vanished as the changes finalized or she removed it when you weren't looking. "Fuck!" she cries out, then continues, "And that's really -oof!- about all -aah!- I can thi-think of to sa-a-AAY about that. Fuck!"

Becky smiles and sits down. You look over at her. "You don't find any of that to be a bit odd?" you ask her, but she just smiles.

"Not really," she says. "It's not odd to put a lot of effort into your cosplay."

"Well, they are all definitely putting in a lot of effort!" you joke, looking at the front of the room where Samantha is now licking Jenny's exposed twat, tail on the ground behind them, and Brad is now slamming into Olivia, her tits wiggling and swaying wildly as she loudly grunts her pleasure.

Becky smiles. "Yeah, now you get it! I mean, their costumes are all from the porn parodies of their various franchises---not what I would do, of course---but they're all super into performing their cosplay." She eyes Brad, who has now removed his pants and revealed a dick of a size you've only ever seen in porn, and sighs. "I love his dedication to the costume. I wish that were me up there."

You raise your hand. Samantha stops eating out Jenny and looks over at you. "Yes? Another question?"

"Yeah, I was wondering if Brad up there would be willing to take a turn with my friend Becky here." Becky turns red and both smiles and glares at you at the same time. "She's a big fan of his."

Brad pauses, deep within Olivia, as Samantha relates the question he couldn't hear over the noises Olivia was making. He turns and nods. "I think," he says as Olivia stands up from his dick with a wet slurp, "that the question and answer phase is complete. We'll be up here for the rest of the hour and we'll be more than happy to answer questions, pose for pictures, fuck you or be fucked, or whatever you'd like."

Becky grudgingly grins her thanks to you, then rushes down from her chair, leaving her clothing on the ground and revealing her pretty, though somewhat ordinary, body as she runs up to Brad. She laughs as Brad leans down to suck on her nipple before your attention slips to the other three cosplayers you are now walking back towards.

The three girls are all now lying on the edge of the table with their legs dangling down and spread. You beat the other attendees to the front since you're the only one running, and after carefully lining yourself up, your hard dick easily slides into Olivia's fucked pussy.

It's still very tight, though, even after Brad's pounding, and it grips you wonderfully as you lean forward to grasp her two tits, which are drooping slightly to each side of her torso, though still more than a handful each. She gasps as she feels you enter her, then smiles at you as you begin to pound her.

"I see someone liked my costume!" she laughs, then begins grunting at your efforts. "Wow!"

You see next to her both Jenny and Samantha have now been stripped fully nude by the other presentation attendees, and both of them are now giving blowjobs to four or five guys surrounding them.

You look back at Olivia and her tits in your hands. They're soft and warm, though the nubs of her nipples are hard in your palm. You stop squeezing one tit and begin pulling lightly on the nipple and are rewarded by a happy squeal. You tug playfully one last time, then move your hand down to gently rub at her clit as you feel your wet dick sliding in and out of her. She groans, and in a few minutes you feel a flutter through her pussy as she screams, "Oh GOD! I'm cumming, don't stop, don't stop!"

Olivia opens her eyes and stares deeply into yours. "Fill me up!" she begs, not breaking eye contact. "Fill me up, fill me up, fill me up!" Her voice is ragged with lust. Still staring deeply into your eyes, she grabs her tits and hoists them alluringly together. Her tongue slips out to give one of her tits a quick lick.

It's too much, and she gasps in an open-mouthed smile as she feels your dick harden and begin to shoot several thick ropes of cum within her. "Oh my god, it's so warm," she giggles, and you feel another unexpected firing from your dick due to that giggle before your dick finally stops. She just closes her eyes and lies still, the two of you both simply savoring for a moment the feel of your hard dick slowly softening inside of her sopping pussy.

As you step back, pulling out from her with a wet pop!, you can see your cum beginning to leak from her pussy as she lifts herself up slightly on her elbows. "Fuck!" she says, feeling the cum leaking down to her asshole, "You really did fill me up. Nice!"

She leans back, satisfied for another moment, before she yells up to the room, "All right, who's next? This pussy is still open for business!"

Another nerd steps over and takes your place as you go back to pick up your clothes and move on. You'd love to stay, but you realize as you see the three female cosplayers all now pleasuring two different guys each, two of them in double-penetrating sandwiches, Olivia blowing one guy as the person who took your place simply rocks back and forth, and see Becky kneeling fully nude on the floor attempting to deep-throat the now-impressive Brad, that this scene could be replicated in hundreds of different varieties today throughout the convention.

You smile as you head out the back doors and past the people already waiting for the next presentation to begin in a few more minutes. A few of them look inside in confusion, obviously not sure why everyone is having sex since they don't have their cosplay on anymore, but also not really shocked about the situation due to whatever magic the camera app is spreading.
