The mc is not a sub.
There are some femdom scenes when the player breaks rules and gets punished, but this is usually the player's choice and can be avoided. Then there were some scenes where mc, Susan and Rachel play sub-dom-games in early game, but this was femdom light on a voluntary base. MC had to set up the meetings and depending on luck he could dominate (spank) Rachel in these scenes.
In the later game mc is quite dominant and now can punish Rachel, Emily, Chloe, Linda and Amy, so there is no option to put him into femdom unless he breaks the rules.
