Roommate
You're moving into a new city to go to college. You're rooming with a girl you haven't met.
She sleepwalks on the first night and opens up the fridge, eating a bunch of food including your leftovers. You bring it up the next day, and she suggests putting a lock on the fridge so she won't accidentally eat your stuff any more.
- Agree to lock the fridge The next night, you hear her sleepwalking trying to open the fridge, you go back to sleep. Your roommate comes in and starts to swallow you while she's still asleep. You wake up partway through, but it's too late to release the suction grip she has on your midriff. You are digested without her waking up, as she gets back into bed. She wakes up the next morning with a pudgy belly. "Damn, not again. It's so hard to keep a roommate around..." She posts a thing on Craigslist: Looking for Roommate. Light sleeper preferred.
- Don't leave any leftovers The next night, you hear her sleepwalking and open the fridge, you go back to sleep. Your roommate comes in and starts to swallow you while she's still asleep. She's imagining eating a sandwich or something
