I think I've done something foolish this evening

I bumped into an old flame today. She mentioned she was a bit short on cash and needed somewhere to crash, so I offered her my spare room. She made it clear that she’s keen on a friends-with-benefits arrangement given our history—we were together for six years and both of us have been switches. She said she’d come see me tomorrow and promised that I can get whatever I want however I want it. It sounds like a win at the moment, but I suspect one of these nights soon she’ll exact her revenge.
