the apocalypse can wait a little (Left 4 Dead Hunter x Survivior One-Shot)

There's an outbreak of Green Flu. A boy gets infected, a girl doesn't. They meet anyway; she takes him in, he heals in her care. They like each other a lot.

And then they get stormed in in a safe, secluded place where they can figure out the tension between them, so they do.

(Porn with some Setup, that's it. Enjoy.)
