Does Ruby ever blow Emerald in public?
"Mhm... well, depends on what you define as public," Ruby explains, slightly blushing. "So, if you mean in a setting beyond our rooms or very private places? Yeah. I sucked her off while we were hidden in a park, and a few times in public bathrooms or other isolated areas. It's fun and kinky. She has her own illusion powers to keep us private in case of an emergency, but we leave that as a last-ditch effort in case we are almost caught."
"However... not to toot my own horn, but I do suck her cock very well, and that gets her focus jumbled. So we have never tried anything more public than that, like using her powers to do it in middle of class or in a busy street. We dirty talked with each other about it, but we know better than to try it. We have in mind some of that stuff with one person nearby, like if we are at home and Yang is not letting us alone for whatever in reason, but that thankfully never came up yet. So... to answer your question, kinda."
