A man and a woman living together. It is noticed that there is no love between the two in this somewhat mysterious relationship. A woman who wants to be fucked by a man who is only a spear. Dense SEX is repeated every time the two are mixed. The devilishness of a man who does not think anything even if another man has sex with her gradually escalates, and at the end plenty of sperm is poured into an unprotected mako.
