Good Omens. Crowley and Aziraphale pose as husbands for a house party, because Aziraphale is bad at saying no (to anyone but Crowley and anyone trying to buy books). Crowley thinks this is a good chance to prove himself the perfect potential demon husband to a fussy angel. But things get complicated fast. Really complicated. A lot of pining, a lot of shopping and restaurants and party games, some near misses, but no sex until chapter 24 (and all of 25).

"Aziraphale debated internally a bit, but curling his arm up around Crowley's shoulder really was more comfortable. He knew he was being silly. He knew a dance was nothing and if it made Crowley happy after his feelings had apparently been hurt it wasn't much to ask, but-it was the demon. He had the literally infernal talent to make even the simplest, least dubious things feel like a temptation. Aziraphale knew it was Crowley's nature, and not strictly saying his fault, but it did sometimes make things feel *complicated*." Biarritz, South of France, 1921. Aziraphale stumbles on Crowley apparently working the hotels and casinos as a gigolo. At least, that's where it begins.
