In this alternative world, when a girl comes on her monthly cycle, she emanates a pheromone from her vagina... and her feet! Your step-daughter comes to you embarrassed, saying that she came onto her cycle in the middle of class in school 2 weeks ago, and because her ma isn't around anymore, you have to explain to her exactly how a females egg gets produced, released, and how a girl (if not using proper protection against the smell escaping) will turn any man who comes into contact with her into a horny, sex crazed . You also say that a female experiencing this, will become promiscuous and extra horny, seducing any man she is near. She doesn't quite believe you, but you tell her that the egg gets produced from masturbating, and so you have to trust her NOT to touch herself in any way, whilst you go to the shops and buy her some special underwear and socks to stop the pheromone when the egg is released. She promises you she won't do anything silly, but, when you leave the house, your step-daughter starts to mess around, rubbing her tight pussy in an effort to prove you must be lying to her. After a minute or so, she starts to have a reaction to masturbating and feels in her belly that something is happening to her... something uncontrollable and she starts to smell her own scent... Then you come home and walk into her bedroom. You stand in her doorway, overcome with lust after smelling your step-daughters sex pheromone... There is no stopping it now... You must impregnate your step-daughter...
