MC is more a switch. He will be submissive or dominant depending on the woman/scene. However you're get more chance to dominate girls, including Erevi later (Erevi will start being more submissive as she grows fonder of you)
Erevi
-Anal when preg (dinner date w/ black dress)
-Tie her to the bed
-Tie her to sex bench
-Spitroast her with MC's double
Erevi'sDaughter
-Stick her in the stocks sex frame.
Alice
-After meeting Naamah you can tie Alice up in bondage & fuck her. Can go further with Phallus G & a gag ball
BatBreeder
-Literally you're sex pet that can be put into sex frames & fucked silly. Eventually trained to love you.
That's just a few examples. It's a bit more leaning on dominant females tho (I have an inkling that Tinkerer himself is into that. Makes sense with the amount of strongwilled women are in the game so...)
