A gorgeous woman in a skimpy Supergirl costume slides into the armchair opposite you at a Halloween party and issues a flirty challenge: prove you’re a real hypnotist.

You were invited by a work friend to a crowded Halloween house party, but nobody else you know showed up. Bored of standing alone, you claimed a quiet corner of the couch in your deliberately corny stage-hypnotist outfit—black tails, top hat perched beside you, monocle, and the old-fashioned pocket watch on its chain—and settled in to people-watch.

A few minutes later she appears. Her costume is high-quality but far sexier than the classic Supergirl look. She introduces herself only as Kara, drops into the armchair opposite you with a confident, alcohol-warmed smile, and after some light flirting dares you to demonstrate your hypnosis skills on her.

She wants to go under—and she won’t resist a single suggestion.
