He's a nerd: of course it does

Crap, David had forgotten about that. As much as he would like to have this girl blow him as well, it would defeat the purpose of the roleplaying aspect if she ended up acting wildly out of character. Besides, another, possibly better, idea was brewing in his perverted little head.

"Oh sorry, you're right," David told her, "How about instead you act as one of the judges?"

"But I don't have a knob for her to suck," the Tracer cosplayer said with a pout.

"That's fine, Hana can just eat you out."

"Hey, what?" the D.Va cosplayer said irritably, "That wasn't what I signed up for!"

David couldn't help but snicker at the irony of that statement.

"Sorry love, but you heard the man," Tracer said to her friend as she pulled her black bikini bottom down her legs, "Now come over here and show me what you can do!"

D.Va didn't look very happy about her new task, but still obligated as a female cosplayer to play out David's scenario, she put a smile on her face, got down on her knees, and said, "You got it!" before burying her face into Tracer's crotch.

If the other cosplayer was at all perturbed by this (which given her reaction before David stepped in, she almost certainly was), she was doing a fantastic job of hiding it. Before long, Tracer had her hands on D.Va's shoulders, a look of utter ecstasy on her face as she let out a lustful moan. She slowly started to lower herself to the ground, guiding her pussy-slurping friend down with her. David watched with rapt attention, his deflated cock already starting to twitch back up at the erotic display before him.

His internal debate about joining in was suddenly interrupted by a soft, feminine voice coming from his left, "Tiff! Emily! What's gotten into you two?!?"

David turned to face the new arrival, and to his delight saw a third swimsuit cosplayer, this time of Mercy. Unlike the other two, she was wearing a one-piece as her outfit, probably due to her smaller figure, though that didn't stop her from looking almost as sexy as her friends.

David knew he just had to have the trifecta, and got ready to **** her into character as well. However, before he could make a move, a (non-swimsuit) Genji cosplayer came up behind the girl and snapped the shoulder strap of her swimsuit to get her attention.

"Yow! Hey!" she shouted, turning to face the Genji with a glare.

"Go into character, Mercy," the Genji cosplayer said, not even bothering to introduce himself, "I need healing. But without your Caduceus Staff, the only way you can save my life is by making me cum in your pussy."

The Mercy cosplayer looked frightened for a brief moment, but took a deep breath and shifted it completely into her performance.

"Genji!" she said to him, in a half-decent Swiss accent, "My God, you look terrible! You need to lie down!"

"Right here?" the Genji replied, in probably the shittiest Japanese accent David had ever heard, "What about your laboratory?"

"There's no time!" the cosplayer replied, practically pushing him to the ground, "I need to see what's wrong with you, right now!"

"Hey, wait a minute!" David interrupted, "I have a thing going here! Can't you go find someone else?"

"Sorry dude," the guy said to him as he laid his back down on the floor, "With these cosplay chicks, it's first come, first serve. If you wanted to play with her, you should've spoken up sooner."

David grumbled and crossed his arms in annoyance. In his haste to set up his perfect convention experience, he didn't think of the possibility of other men having the same privileges as him, nor of the possibility that they would actually use it. And like with him, passerby were giving the two a wide berth, but despite their disgust made no attempt to stop what was happening. Lesson learned, he supposed.

Mercy for her part didn't even acknowledge the argument between you two, fully committed to her role. She pulled down the pants of Genji's costume (which admittedly does look good for something obviously homemade) and gasped when she saw his penis, "Oh my! Genji, I think you have been poisoned with Talon's Blueball toxin! You need sexual release immediately if you want to survive!"

"Angela, please..." the Genji cosplayer 'moaned', going back to his borderline offensive accent, "I'm too weak to do it myself..."

"Don't worry, I'll take care of it," Mercy replied, licking her lips, "You won't die on my watch."

As the Mercy cosplayer got ready to take Genji's flaccid penis in her mouth, David was faced with a dilemma. He had the Rulebook, and with it an easy way to fix this problem. But the real question was, did he want to? After all, he already had two other girls currently playing out his fantasy, and it felt kind of like a dick move to steal a third girl from someone else, especially since the Genji didn't appear to have any other cosplayers with him. On the other hand, he wouldn't even be able to get with this one if it wasn't for David and the Rulebook, and he wasn't exactly polite with how he snatched her away without so much as asking first. He might not have realized it, but he disrespected his benefactor, which could be enough of a justification to take away his privileges. Plus, David wasn't sure if he could wait however long this guy decided to take with this Mercy before being able to have his turn.
