She then realizes that if she doesn’t change anything over the next several months guy before the change will start to grow breasts, losses muscle and become for feminine, have issues getting hard, and stop making as much cum. Also, that women before women will have their breast shrink, gain muscle and become more masculine, and have their clits get a little erect.
Before making any other decisions Ty decides to wish any unborn children will be one normal gender, to prevent the end of all humanity. What happens now . . .
