Plenty of Foggy/Karen/Matt out there, but I'd really, really love a story with Foggy and Karen having sex with Matt, and him just taking it. I'd love a scene with them all drinking together, like at the end of 1x13, but by the end, the table is flipped over and Matt's being held down by one and fucked by the other. Bonus points if Matt's got a hand over his mouth at some point. Consent doesn't need to be verbally given, but they should all be enjoying it.
