Money Shot, book 2
Tim Seeley, Sarah Beattie et Rebekah Isaacs2021

he 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. Collects Money Shot #6-#10.
