Elf King Kyle has heard rumor that an assassin is coming for him, so he hires local mercenary Christophe to be secretly positioned in his room and protect him. Christophe claims the assassin doesn't stand a chance because nothing can break his focus and he'd never give his position away- Kyle decides to test that using his telepathy powers.
(the assassin can end up being there or not, doesn't matter. what matters more is kyle teasing christophe, christophe being extremely tempted, maybe christophe being able to hear kyle touching himself while projecting his dirty thoughts, etc. can be 1 night or multiple nights sort of build up)
