   Summary

   Rocky and Grace are so impossibly different form each other that a conventional sexual relationship isnt attainable in the slightest. But their pull for one another is too strong to pay much mind to that fact.
   How can two aliens who can't even touch each other have sex? They're going to figure that out. For science? For love? Maybe a strange and exciting combination of both.
