Discord accidentally swaps the genders of many in Equestria (Including himself) He She then proceeds to have sex with basically everyone, one chapter at a time (Sometimes even multiple people per chapter)

It's porn for the sake of porn, what do you want from me?

Chapters will be marked for Genders within I.E M/F M/M F/F M/F/M F/F/F/F/F/F so if something doesn't float your boat you'll know where to go.
