OLD BEST FRIEND AS FREE USE HOUSEGUEST

It's been ages since you heard of Sienna. Back in the university, you used to be an item, on and off - but besides occasional dating, you always just enjoyed her company. After you drifted away from each others' beds, your friendship remained strong, and you still kept touch and met for coffee and lunch. Until you graduated.

Then, you parted ways - until you got a phone call. Sienna was coming to London for two weeks, to study some books in the Royal Society. She's an undergrad in the University of Rome, and would like to meet you again. To be more exact, she'd like to stay in your apartment. For two weeks.

Money is tight, so she'll not be able to pay, but she has a different proposal: Free Use. Okaying you to initiate whenever you want, however you want, no questions asked. It's not as if you two haven't had before. But this is new. You never thought Sienna would be into it, and it seems there's a story to be told there.

So you said yes. Truth be told, you'd have let her stay for free anyway, but this... is a definite bonus.

So one day, you arrive at home, take off your coat, and find Sienna sitting on your couch.

It's going to be one interesting fortnight.
