Yes...and grade her

All his life, David had wondered how he would get his first blowjob. Even more than just plain sex, to him, the blowjob was a sort of ultimate form of submission. For a woman to get on her knees, to place such a dirty thing into her mouth and suck on it, to focus entirely on his pleasure...

He never imagined such a beautiful cosplayer would be giving him one, the D.Va faithfully on her knees, sucking him off. He had his head leaned back and his eyes closed, but he was acutely aware of every movement of her wet tongue. The best part was that he knew that deep down, this girl hated what she was being **** to do. But she had to hide it behind her acting as D.Va. It must have been humiliating considering that before her switch into character, she was about to go off on him for exposing her chest. Instead, she was greedily engulfing his cock, the competitive nature of the Korean starlet ensuring she would do her best at this.

This was all being done in public as well. She was blowing him at the exact spot he first approached her. Everyone passing by was looking at the scene with quiet disgust. His rule didn't state that anyone had to like it, but simply tolerate it.

It wasn't long before David began to groan. His jizz cascaded into her mouth until he had nothing left to pump into her. D.Va allowed herself to back off from him, holding his semen in her mouth. She looked up at him, waiting for an answer. Of course, David was too out of it, enjoying his first ejaculation into any girl's mouth. D.Va couldn't even speak up, not wanting to spill any on the floor in case that wasn't what David wanted.

He finally looked down at her, and even then, it took a moment for him to realize what she wanted.

"Ah, yes...you can swallow if you like, Hana." David said, and the cosplayer actually took a bit of relief in finally being able to swallow his load. Once her mouth was all cleared up of his spunk, she finally spoke up.

"So? What do you think? Is it enough to win the competition?"

David pondered on the question, letting her stew while waiting for his response. She wouldn't like the answer.

"C Plus. Could use some work."

"What!" D.Va said in a surprised tone. "That's not fair, let me try again!"

"TIFF! What are you doing!? Where's your bikini top?"

Both of them looked to their left, noticing another swimsuit themed cosplayer. It was, in fact, one of D.Va's friends. David suspected as much, since her cosplay was following a similar theme.

Before she could say anything else, David naturally had to step in, quickly forcing her into character and explaining to her the competition at the panel. Tracer, who had been speaking in an American accent, was suddenly speaking in Tracer's signature chipper British accent.

"Oh, I didn't know we were here to do that! It seems odd picking me for this mission, though. You all know I'm a lesbian."
