You met up with your friend Ishii after she sent pictures of her cloaca and a series of explicit text messages. You take the train downtown to her megabuilding. She lives in Nagatown, of course, like the rest of her kind. A few decades ago, a confederacy of alien species occupied Earth. Humanity eventually pushed back and regained their independence, and is now learning to co-exist with a generation of Earth-born aliens in a post-occupation world. Ishii is of one such species, the Nagawa, a serpentine folk whose venomous and constricting nature were used to deadly effect in the initial invasion. That was before her time, though. They tend to nest in urban centers with lots of heat lamps, so Nagatown feels like summer year round. The vipers watch you with narrow slits as you mosey through their territory on your way to get laid. "Hey snake charmer," Ishii hisses as she lets you in. Her tail swings the door shut and locks it behind you as her hands loop around your waist. Her heat-sensing hood folds outward and her tongue flicks against your cheeks. "Thanks for coming by."
