Why is everyone saying the ending is "wholesome"? This relationship is doomed to fail due to the revelations in it! They both were in it for sex from the beggining, and the main thing that brought them together were their complementary fetishes. When the older one stops being an "atractive older lady" and becomes just an old lady, or when the younger one grows up a bit and stops being a "cute loli", whichever happens first, their relation will fall apart.
