from what i gathered so far, a "true" ntr dinamic is set up to develop in another couple, between the best friend and ari. eric, even though he is still inexpiriences at this point in the story, has always managed to gather respect from the people around him ( i.e. even ari prising his dick at every given opportunity and vi bragging to ari how hard eric is baning her in bad), so it does not look like this story is going the humiliation route for the MC. more like he slowly "growing" into his position of having a bunch of very promiscues women around him and learning how to "manage" them and get as much pleasure out of it as possible. just my observation
(still hoping he gets dips on younger sister and mom
