Kao no nai Tsuki, Koe de Oshigoto! The Animation Recommendations
Lots of moaning, groaning, wailing ,crying, sexy voices, you name it. Basically these shows present you a lot of sounds a woman makes when she have sexual intercourse. Should be pretty useful for people with Narratophilia. (I spent sometime wiki that)
And under this categories I used, Koe de Oshigoto itself would be compatible as a reccommendation for any H-anime, unless it is muted. Go ahead and recommend all H-anime on your list with Koe de Oshigoto to your heart content.
