Not so much a seductive storyteller, but a seductive sex therapist in Kodaka Kazamu's manga: http://www.mangago.zone/read-manga/sex_therapist/
This is a good one with a seductive/confident uke: http://www.mangago.zone/read-manga/kuchizuke_wa_uso_no_aji/
This story is more in the POV of the seme, but i think it's still pretty good. And the uke is projected as a confident yet arrogant person. :)

Does anyone know yaois with a very seductive (and maybe confident) uke as storyteller? I've read too many mangas with handsome semes lately, I need some change xD I like everything except tragedies, thank you very much!! ^-^
