Penetrative sex where sperm permeates the vagina is truly sex. The pleasure of fertilization must be the internal ejaculation that women seek. It is a scientifically proven fact that the act of a woman directly absorbing male sperm in her body (vagina) in her own desires enhances her female hormones and brings abnormal pleasure. Sex that women crave, sex that women are immersed in, sex that women seek on dangerous days without contraception, internal ejaculation. Verification will be done with the person who loves internal ejaculation, "Saki Hatsumi."
