First thing I'd do as an Omni is reincarnate myself into a world exclusively populated by sexy girls and traps traps/twinks and just make myself the most masculine/strong/attractive guy on the planet.

It's an incredibly basic wish-fullfillment fantasy, but I just wanna hook up with lots of girls and boys and keep them as my personal playthings and sex friends at my beck and call. Being desired/lusted for wherever I go sounds pretty fun, and so does being able to seduce/impose muyself onto anyone and being able to turn them or their own partners into my sex pets, all the while their partners seethe about being cucked/wish it had been them who had been taken.
