I think i finally realized the 3P. Everyone must not be a virgin if the conditions are met( all 3 are happy with each other). Such a stupid limitation and l knew one Boolean value was enough to block the 3P because the third person would always masturbate.
Maybe 2 need to be non-virgins, l really didn't test throughly.
My conclusion is that all 3 must be non-virgins.
My test was with 2 futas and 1 female.
Maybe next time i will test without needing to be loversm just they have high relationship with all 3 but the mere fact of not being a virgin, hurts the immersion a lot.
On my anal only couples, l couldn't do 3P despite, in theory, 3p having animations that don't use the vagina.
Alas, sadly this game isn't "immersive" in terms of anal only unlike AA2, unless it has been already fixed a previous bug( l have 1.5 version)
Still, finally good to close this chapter on why people make cool concepts but their acquisition is abysmal and the solution is more cryptic than 90s puzzle games, especially Sierra ones. Obtuse much?
I doubt AA2 has 3P with futas and female even while using Modules, l only remember it doing with 2 females and 1 male. At least, it is introduced in AA2 "summer vacation".
