Imagine that you have a second wife who has a young, hot daughter from her previous marriage. Now imagine that your dear partner just went out to a spa, and you're left alone with the aforementioned gorgeous stepdaughter - Katrin Tequila. Of course, you pretend to read a fitness magazine and just not care about anything. But Katrin wants to have some fun - she thinks what you are doing is boring. You can try to resist for a while, but soon Katrin will seduce you and there will be no other option, just to let her do what comes naturally. Natural instincts just won't go away, whether she's your stepdaughter or not.
