Hmmm... when she get those is it futa or temporary replacement?
And if she actually goes all the way with mahiro and mahiro somehow got detoxed what happened to the fetus?
@Metalwolf according to extensive research there are alot of cases of futanari impregnation and since there is no prove yet in this manga the existence of balls soo we should be able to assume she could impregnate in the name of science
