how aboub lesbian/girl on girl im not a fan of it at all so always like to find out if it can be avoided including during threesomes and between girls in the harem
There will definitely be lesbian/threesome scenes down the road, but it will probably be a while until the characters reach that point.
Regardless, they will be completely avoidable if you don't want to do them, and they will most likely not affect each woman's individual routes, if you only wish to pursue one.
