So God said "let there be Secret"; and there was Secret, and God saw that it was good. Amen.
All 4 of them though, seriously. And even though Jieun and Sunhwa aren't on the same league as Zinger or Hyosung, if it came down to it, I'd be perfectly content fucking their legs. I don't even mind if Sunhwa keeps those sexy-ass stockings on, they look kinky as fuck.
Gawd, who wouldn't want to fuck Jieun?
But enough fangirling. Zinger still looks and sounds like ass. Sorry.
