A daughter who witnesses her mother having a rich SEX with a man other than her father with a random chance. Although it is surprising, the obscene expression that I have never seen before is the face of a "woman" instead of a "mother". The crotch that the line of sight is glued to the appearance and gets excited and gets wet. The estrus body transforms the daughter into a lascivious woman, and the man who was holding his mother until a while ago develops more dense SEX.
