No, no. Not a sleepover at all.  Very sexy moment and also really vulnerable.  I've been reading this story thinking "Fionna is the black Daria" and trying to date.  It's been fun watching her soften.  Your Justin is tough... or a masochist, I can't decide.  ;)  I'm sure she's gonna toughen back up and fuck all of this up, but man, I'm invested and can't wait to see how it all shakes out.  great job!
