Money Shot #6 (Mature)

"The XXX-plorers embark on their second mission to a naughty world (that may have inspired the biblical Hell...or at the very least ripped it off). But whips, chains and spanks have nothing on the torture of STD testing! Meanwhile, a powerful romance rocks an alien empire to its core, with intimate consequences for our scientists-turned-porn-stars! A great jumping on point for new readers -- or a comfortable place to sit and rock for current fans."
