Misuzu is a solitary and calculating woman.
She has probably been GB by a number of men, who will rank which man has the biggest BBC, which man has the best piston movement, which man has the longest lasting erection, etc., and she will determine which man has the best genes.
She will persistently verbally torture the other men, how unnecessary and worthless the semen ejaculated into her vaginas is for the rest of her.
