One could argue the MC is a master and the women are his slaves, and that a slave's sole purpose is to sexually please the master anyway he wants, so something like using a strapon would be in the reality of it if the MC asked for it, but not be forced into it.
Then again theoretically, there could also be that by the MC saying he is a monster and forces Ruth to show her panties, and the fact she is against all of the headmasters stuff, and you are blackmailing her, a possible outcome could be she would hit her limit and then blackmail the headmaster back.
Both are plausable, however at this point given there is only 2 women you have sex with, get sucked off by 2 students, and jerked off by one of the 2 that sucked you off, it is not likely at this point in time.
Now whether or not it gets added to the game is another thing, given the game is a heram one, and about male domination, femdom really doesn't fit in with it.
Of course, femdom in a porno game is like ntr and pretty much a game killer.
