Both yaoi and (m)m/f haha. Uke gets along w two semes, one day gets cursed by chocolate to turn into girl at night until man cums inside him. Starts w one seme, until seme goes to look for something to lift curse and leaves him with second seme. Uke likes them both, curse lifted but some effects continue and uke confesses to both for a happily ever after 3p relationship. Ongoing, but hiatus and resolved enough to mark complete.
