Sadly, it will be because of futa. There will be lot's of Futa Content and it wouldn't be optional.
BlackWebGames doesn't care that the People wishes that his Lesbian Games stays Lesbian only and that they don't want futas.
Yes, I would have preferred a scientific solution to the problem.
However, a futanari mother + daughter couple is still pretty rare and a mother and daughter having a baby together
even more. I know of only one game where that is possible, "Sims".
Currently there is one vn in the works which will allow it, "Ariana's perverted diary". That's it.
Futanari in MLS will be by the looks of it the kind I find more esthetically pleasing, i.e. without visible balls.
It's not like the previous chapters will magically disappear. I'd rather play MLS than a game where maybe, possibly, if the devs be merciful, I'll get one mother and daughter scene in the next ten years.
