Dialogue? You think this Dev is gonna add dialogue even though after this many updates it's all the same voice. Dude could buy moan packs from a Few different VA's and at least have some tone/pitch variety. Hell there's plenty of free NSFW sfx/moan audio packs out there with a variety of voices, plus modulator programs to adjust pitch/tonality/resonance/etc are also freely available.
All those resources & tools are out there but yet it's what 20+ characters now all with the same exact audio.
