STARLESS nymphomania 21sr century-What if?

I liked everything about the game, expect the only thing I would change is make the part where Maria asks the Main Character if he wants a penis enlargement it should be interactive because I really want see how the story changes if he had said yes.
what do you all think would have happened? How much would it have affected the story? Would it have been big or small? Could that new decision have branched out and created new future choices?
