Someone needs a new costume

Rachel walks off and you grab a nearby map of the expo center and sit down at a bench to review the schedule and the layout and to play the day.

There are relatively few cosplayers up and about yet because you entered so early on the first day. Maybe you should have arrived later or maybe you should have stuck with Rachel. You sigh, impatient to make full use of your pass.

A pretty woman sits down next to you and also sighs. You look over. She's very pretty, with wavy hair just the shade you like and large dark eyes. And while it's hard to look away from her striking face, the rest of her isn't a bad sight either. Her neck is long and narrow and she's dressed in baggy pants and a loose T-shirt and opened zip-up hoodie that together almost disguise the impressive size of her chest. She sees you checking her out and the barest hint of a smile crosses her lips. You introduce yourself.

"Nice to meet you, I'm Melanie," she says.

You're about to comment on her chest when you realize she doesn't seem to be wearing anything that could be counted as a costume. "Are you dressed as somebody?" you venture.

"No," she says, her face scowling at the ground. You breath a quick sigh of relief that you weren't so forward. "I was going to be going as a space princess from an obscure seventies popcorn flick. I recently got a job working for a streaming service that specializes in terrible old sci-fi movies and was going to be working at our booth in the costume. But my sister's family is also in town and my niece ruined it last night. Now I don't have anything to wear that isn't stupid and generic." She sighs again. "I like to wear obscure costumes, but not so obscure that at least someone doesn't recognize it. It's like a fun game."

You sigh, too. You'd really wanted to get a look at what she's hiding under her shirt. She hears your sigh and looks over. "Thanks for the sympathy. I just can't think of what to do."

"Well," you say, putting a hand on her shoulder, "maybe we can brainstorm something for you." She glares at the hand and you quickly remove it and apologize, remembering again that she's not actually cosplaying. Time to change that, then!

"How about we experiment? I'm sure we can find something. Why don't we just start small and see if it sparks any ideas? You've got that hoodie on. Come on, stand up," you say, and she lets you help her to her feet. "Why don't you take off the hoodie and tie it around your waist?" She does so, uncertainly. "There! See? Now you could be any of your pick of dozens of characters from a 90's TV show!"

Melanie smirks at that. "Yeah, okay, I guess so. Like Buffy or something, yeah?" You nod and reach out to hold her shoulder again in support. She watches your hand but doesn't react to it. She just looks back down at her hoodie on her waist. "It's just so generic, you know? There's gotta be something more recognizable."

"How about we keep going, then? You've still got more to work with. How about you take off your shirt and let's see if we can do anything with that?"

She shrugs, pulls the bottom of her shirt through the tied hoodie, and hoists it over her head, revealing a bright blue sports bra. It's impossible to hide the size of her tits now as the bra is impressive enough; you'd guess that she's a DD but it's impossible to be sure with them tied down in the stretchy sports bra. "How's that?" she says, tossing the shirt to the bench. "Any ideas?"

You reach down and grab the hem of one of her trouser legs and start rolling it up in wide, thin folds until it's past her knee. "So with the sexy top, the hoodie, and the mismatched pant length you could be a character from a JRPG game, like Last Fantasy or something."

She looks down and around herself, nodding. "Yeah, I can see it, kind of, but I can't think of any specific character who looks like this. I wanted something that would be hard for people to recognize but would still be something real. This just isn't specific enough."

"Okay," you agree. "Let's keep exploring. Let's lose the bottoms. Everything."

She stutters and seems about to protest, so you just reach under the tied hoodie and being unbuttoning the trousers and pull then down from her wide hips, then with your thumbs you also grab her panties and quickly pull them all in one move down to her shoes. As you stand back up, she gingerly steps out of the crumpled trousers and panties. She's standing now only in her hoodie, sports bra, and shoes. Her pubic mound is clearly visible to everyone walking by, covered in a thin, trimmed bush the same shade as her hair.

Now that you've stripped your first expo visitor you suddenly realize the event might be actually starting now as there suddenly seems to be a lot more people around. There's a brief moment of irrational panic as it's been a long time since the last convention and you're not used to this anymore but nobody seems to be giving the two of you much attention so you're able to **** that panic away.

"Hmm," you say as you step forward and start rubbing her crotch and massaging her bush, "I think that looks pretty good."

"I don't know," she says, then her voice wavers as your start running a fingertip gently between her labia, "I can't think what character would look this this." Then she gasps as your questing finger slips a bit into her moistening pussy and begins exploring within.

"You're right, we should keep going. I'm sure we'll think of something."

She trembles slightly and looks into your eyes, her face uncertain. "I only have a sports bra on; if I take it off I'll just be completely naked and I'm not sure that's a costume."

You're not sure how to respond, but are saved by a random stranger who overhears it. "Sure it is!" He's a bit older than you, but you wouldn't be able to pick him out of the crowd if he hadn't stopped. He points to Melanie's chest as you continue to work your fingers more fully. "There's plenty of naked characters your could cosplay like that." You remove your wet fingers and move them to her mouth for her to lick them clean, then you reach down to start massaging her surprisingly firm tits within the thick sports bra cups. "I mean, there's the naked chick from the space cowboy show that got cancelled too soon: you've definitely got the bust for that. And there's always the space vampire from that terrible 1980's sci-fi film, Lifeforce." You reach down to grip the bottom edge of Melanie's bra and start to slide it up. She's distracted by talking to the guy and absently reaches around to help.

"Wait," she says, "this was a bad sci-fi film?"

"Yeah," he responds as he completely ignores the fantastic titty drop going on in front of him. "It's a movie about astronauts finding this vampire in space and they take her back to Earth." Which is fine: you'll just have to enjoy it for him. Which you do, reaching around to squeeze them sensually and heft their surprisingly firm masses. She must be wearing the sports bra for comfort to lift her heavy bust, not to keep them from drooping. "And she ends up sucking the life out of everyone around her. Plus she spends the entire movie naked, just like you. And, if you don't mind me saying so, she looks good nude but I think you're more amazing than she is."

You're happy he can at least appreciate Melanie as much as it seems anyone else can right now. But as you remove your dick from your pants and line yourself up behind her, bending her forward slightly, you have the freedom to appreciate her even more.

"Wow!" she says, a little louder than she probably intended to as you've just pushed at the same time in an inch or two into her. You pull back and push in further, her juices slicking your cock. "I'm working for a (grunt) company that -oof- specifically streams bad sci-fi -oh!- movies!"

"Awesome!" says the guy as you start to pound her from behind. Her hanging tits seem even larger now. They're swaying and softly clapping together, applauding your performance. "What do you do?"

"Well, oh, god I'm a devel— oh! —a developer and I (ungh) work on the streaming p— POR-tion of our site." She gasps and tries to catch her increasingly ragged breath.

"No way! I've always wondered how that sort of thing worked."

The angle is a big awkward, so you pull out and twist her to lay down on the bench facing up, her tits flattening slightly and spreading to each side of her chest. Melanie lifts her head forward slightly to keep talking. "It's not that hard," she says.

"Unlike that dick, right?" he chuckles. She chuckles a bit, too, looking down at where your dick (which is indeed hard) slides into her in one motion to the base. She gasps loudly and her head falls back in passion. You pull out and slam in again. This is a much better angle!

"We just---" she gasps again, her eyes still closed, "use the fuck! built in WebRTC oh, my protocol that all," she is only able to finish her sentence through clenched teeth, "modern browsers have. OH, FUCK!" Her breath is rushing in and out of her nose as she begins a deep moan that rises in pitch and volume. You keep slamming into her, shaking her voice, as it rises to a wail. And then she slumps down to the bench, gasping, as you can feel her trembling around you. It's almost too much and you want to savor it, so you slow down. She struggles to catch her breath, still moaning as she cums.

The guy is mercifully quiet, maybe he knows you want to appreciate the moment. After a few seconds you're not as close as you'd been and start rocking back and forth gently again.

Melanie leans her head up again, flushed. "But I'm just here today," and stop to pant for a bit as she tries to coast the orgasms a little longer, "to help man the booth."

"Well, then, you have the perfect costume for it," he says, giving her a thumbs-up. "I love the attention to detail, even your nipples are erect!" You look down, watching them as they roll with your rhythm, and reach forward to press your hands into her firm tits. "Just make sure to be extra sexy, then, like the character!" And he walks off into the crowd again.

"You are already damn sexy," you tell her, surprised at your honesty. Melanie smiles and you can tell she'd be blushing if her face wasn't already red with exertion. You're near your end again. "Honestly!" you say, "Trust me, I am deep within your pussy and grabbing onto your amazing tits and," you begin slamming into her again, "IT! IS! AWESOME!"

"Oh! OH! That's great," she attempts to say. It's hard to make out anything else as you're now going to town and her voice is now violently trembling as she speaks. "I'm so happy I have the perfect costume, I can't believe it was so easy. Oh! Oh, god! I've literally had it on my whole life under my clothes!" She groans, pushing and squeezing against you as she starts to cum again.

"That great," you reply, leaning down to suck on her nipple as you continue to thrust your hips madly into her on autopilot.

"Fuck, fuck, FUCK! Wow! Oh!, OH!" She seems to realize something, "Oh! I need to get to my booth. OH MY GOD! -oof!- How— gasp! How much longer are you going to be?""

"Let me just finish up in here..."

"Wait, what do you mean by 'in here?' FUCK! You just got REALLY hard! WOAH! Are you saying— OH! OH! OH! Oh, my!" Your dick seems to keep firing more than you've ever felt it go before. "WOW! You just keep going, don't you? Oh, my GOD!"

Finally, you collapse, not coincidentally with your face between her firm, soft tits. You begin sucking on the nipple by your face again, enjoying the afterglow, squeezing her other firm tit.

"Hey, wait!" she says, suddenly upset. "I had the perfect costume, I could have used it all the time, but I can't use it if I'm pregnant! Who ever heard of a pregnant space vampire?"

You pull out of her tight twat with a wet shlork and a light pop, causing her to gasp. "Hey, even if that's the case," you say, still panting, "you can still enjoy using it for the rest of the expo, at least."

Melanie stands up, grabs her sidepack and stuffs her clothing into it, and throws it over a shoulder, the shoulder belt sliding neatly between the twin globes of her impressive breasts. "Fine," she admits after a bit. "You're right. I'll enjoy it while it lasts. Now what should I do about this?" she asks, a finger sliding a glob of cum from her groin.

"You should keep it," you say. "What could be sexier than a space vampire who's already had sex? It shows that you're a slut who is willing to take any man. How sexy is that?"

"I guess that makes sense," she nods, then wipes her finger off next to the rest of the sloppy mess of her groin. "In that case, thank you for plugging me so full of cum, it should last a while." Then she walks off into the crowd, stark naked and yet still cosplaying.

You make a mental note to be sure to visit her streaming site's booth later on in the expo for another round.
