Gabriel
Mistakenly summoning a lust demon was not on Gabe's to-do list, but with a meddling grandmother, he's gotten used to the unexpected. The real trouble begins when Gabe realizes exactly who he's summoned. What's a guy supposed to do when an Infernal King of Hell has decided he's staying and wants to follow Gabe around like a stray puppy? Add having a job as a teacher, living in a family of meddlers, and dealing with a bureaucratic underworld, and Gabe is about ready to lose his patience. When the Prince of Lust decides he's going to help Gabe figure out his sexuality, though, things really start to get interesting. Maybe mistakenly summoning a demon wasn't the worst thing to happen after all.
Asmodeus
Asmodeus has dealt with humans and their lust since they were first created, and he has never met someone immune to his powers. So when he's forcibly summoned (which should be impossible), and he realizes he has no power whatsoever over the human (which hasn't happened before), he's more than a little intrigued. No way is he going back to hell when he's found such a mystery. When he realizes that Gabe is confused about his own sexuality, Az happily decides to help him figure it out. Who better than a lust demon for the job, after all? If Az happens to get slightly obsessed with his human in the process, who's going to tell him he can't keep the guy? Now Az just needs to convince Gabe that keeping a lust demon around forever is the perfect plan.
