Go to the bathroom to masturbate

Marigold took a moment to recover, trying to figure out what the best thing to say to her waiting friends would be. But thoughts of everything that she had seen dominated her mind, keeping her from thinking properly and giving a proper answer. It was difficult to even hide the physical signs of arousal from her fellow cosplayers.

"Yeah, I'm totally fine!" she insisted. "I think I'm going to go to the bathroom for a second though. Can I meet you guys back here in a few minutes?"

The others seemed to have no problem with that. It had been a long day already and Marigold's friends were all more than eager to have a break, letting them sit down and rest their feet for a little while.

There was a voice in Marigold's head that told her what she planned to do in the bathroom was wrong. She was in a public place, in a convention hall. Spending all that time in the bathroom 'taking care of business' would take up valuable convention time, too. But no matter how many reasons came to mind, Marigold knew what she'd be doing as soon as she got to the bathroom. What she had seen on the convention floor today couldn't be put off until she had private time at home.

She had gone too far, now. 'Decency' and 'respectability' were things for people who didn't look at their friends naked, especially without those friends knowing. Marigold was a new person now, and she knew it. More importantly, that meant she could do what she planned to in the bathroom without feeling guilty about it.

The cosplayers had a special bathroom to their own. It wasn't quite private, since there were just too many of them to have single bathrooms and still have enough for everyone, but it made sure that cosplayers wouldn't be pursued by 'fans' (and perverts) into the bathroom to get a closer look at them with their costumes off. That kind of quasi-privacy was exactly what Marigold needed right now.

She pretended to be her 'old' self, polite, meek, and nice, as she rushed to the bathroom with her staff between her hands. As soon as she arrived at the bathroom marked COSPLAYERS, she felt her heart beating faster. She ducked inside the women's bathroom and picked out the biggest stall: she needed her space.

Marigold stripped off her armor first, dropping it on the ground with her skirt and her staff. With her hands shaking as they were, she really struggled to get the parts of her costume off. It felt like it took her minutes to get everything off, until she was standing alone in the stall in only her somewhat illicit underwear. A little chill ran down her spine, as if she still couldn't believe that she was about to do this.

Marigold sat down on the toilet seat. It was cool, even through her underwear. Cheap plastic, a little too rigid to be comfortable. She found her hand drifting southward already, struggling with what to fantasize about. Images of Joy and Lynn's beautiful, curvy bodies popped into her head, the two women hugging one another... laughing. But Mari couldn't focus on that thought for long, because within minutes there were intrusive thoughts of Terri and Lynn, back when Lynn had been grinding against the beautiful Terri. Inadvertently, the D. Va cosplayer had created her own porn for Marigold. And of course she imagined her beautiful friend Kiona, with her chiseled body. The little golden nipple-piercings hung in Mari's mind, impossible to ignore. How had she ended up with such beautiful friends? And how had she ended up masturbating to the thought of them in a convention bathroom?

Her fingers were soaked. She was leaning back, her head against the wall with her hand in her panties. Her other hand was groping her breast, rubbing her own nipple even through the fabric of her tight compression vest. What was she doing? This wasn't her, she was a good girl. But she didn't want to be a good girl, she wanted to be bad.

Involuntarily a little yelp escaped Marigold's mouth. She flushed red in an instant, clapping one hand over her mouth and staying perfectly still. Maybe if she didn't move, didn't make another sound, then anyone else in the bathroom would write off the sound and go about their day at the convention. But she wasn't so lucky. A familiar voice spoke out.
