Okay... I think I've lost what little mind I possess. I could've sworn I had previously searched for this fiction so I went backwards on the posts here (going back three years' worth!) and found nothing....
So here goes... Loki and Tony are together. They've been together for awhile and expect to be together for a long time (Tony's mortality has been fixed or changed or something). They are on Jotunheim for Loki to work with the elders/government/his family to 'fix' the damage done to the planet by Odin/Asgard/Thor/Loki???
While Loki is doing his thing Tony is visiting a festival with Loki's cousin(relative). At some point they come across a stall that does body paint and Tony is fascinated. The relative talks Tony into getting the body paint while he goes and gets Tony one of the more traditional outfits (including skintight leather pants and a swath of fabric that is artfully draped over his upper body). Tony of course looks great and cannot wait for Loki to see him done up. They then come across a dance area. The relative talks Tony into demonstrating some of Earth/Midgard's traditional dances and he ends up teaching a class... sort of.
Loki comes upon the scene and then he and Tony demonstrate the Tango.
Does this sound familiar to anyone? Any help would be greatly appreciated. Thanks in advance.
