I'll grant you that it's somewhat odd that the dev who, IIRC, is a dominant woman in her own private life, hasn't included more options for the female play
You really think so?
Strictly speaking, she is already towing a fine line of that crazy three letter word that seems to send people in a frothing at the mouth frenzy.
No woman who Kane can be intimite with, expecially the actual LI's....will never do anything more than what they currently already have until much later in the story and then it will only be on the sub-side because ultimately, I'll say it once more for all the haters, SubKane does not willingly submit to what he goes through and endures, he is a slave, and slaves have no choice, option or voice unless given to them.
Tess has already said, cuckolding is possible later in the story...and the 'SubRomances' are probably really
not what a lot of people are thinking/hoping they will be....actual LI's on the DomTrack will never push the envelope (more than we have already seen) with another man...ever.
There's also in-game lore and facts, there's a reason all the slaves use their tongue. a reason you can modify people's tongues (and some already have been before the start) and a reason why so many different characters keep telling Kane (domtrack) the same thing over and over and over again...all the men are pathetic and useless.
