All, and I mean ALL of the sex scenes in his games have been consensual and very friendly. It seems highly, highly unlikely that that is going to change.
And that is very good, I think.
I do not know if it is only me, but I find that there are many more games where the woman is always submissive and humiliated. As far as I'm concerned, I don't find it super interesting, I prefer when the relationship is 50/50.
I hope that Siren will continue on this path there, especially since, I believe that Scarlett Ann never made drawings or the woman is humiliated to see more.
By cons, for the story of Zombie Retreat, maybe the L-001 will not rape the women of the house, but seduce them so that they want.
Personally, I find it both exciting and uncomfortable. To see how the story will continue as much as there will be the sequel with Zombie Retreat 2.
I also wonder which characters will be present!
