Looking for a politcian or CEO who has been hiding his omega status and heat very well, but something happens (maybe he forgot his pills on a trip, or an alpha enters his life, or an exceptionally strong alpha enters his life) and he goes into his first heat.
Alternatively, I'd love a male Avenger or another hero from DC or Marvel who goes into heat. Superhero doesn't need to be portrayed currently in movies, we can find new faces.
Second idea modified from a het idea from a sexanon poster
