Sorry for the super late reply! Itchio doesn't alert me of pending posts so I have to check that separate inbox whenever I remember to.
There will be a specific futanari character, a miniboss of sorts. As long as you don't aggro her you'll be good, and if Bibi does get caught, it will only show if Bibi is standing in range of the camera. So this particular instance of futanari will be super avoidable this time!
