A maniac world reached by those who are extremely sexual. Loss of virginity, insertion of foreign objects, vaginal cum shot during a pregnant woman, SM, genuine oyakodon... A strange eroticism performed by perverts who cannot be satisfied with ordinary sex. However, there lies an unseen pleasure. A man who sees a girl with an anguished expression as her hymen is broken and makes her cock even hotter. A pervert who pushes up a pregnant woman who shakes her big belly from below and makes her a 'parent and child'. This world is full of mysteries of pleasure.
