Lock-in with an Orc

Derrek, a cocky human adventurer, must quarantine with his fellow party member, the burly orc Gromnar, for several days. He's annoyed, but not worried. Sure, he's heard the saying - "Lock an orc and a human in together, and when you get back, you'll have two orcs." But that's only a danger if you're weak enough to be seduced into becoming a big, sexy, hairy orc. So he's in no danger...right?
