You're an altar boy in a Christian community and you love your religion so you're a little concerned when something starts happening to you which does not feel Holy. In fact, it feels like a sin. You've started feeling your genitals getting hard whenever you see an attractive woman - so - panicked, you visit the head Nun in your Church to ask for advice. She knows exactly what is happening to you, of course, but she uses your panic to blackmail you. She tells you that your hard cock is the work of the Devil and that you must not tell anyone else because you'll be shunned from the Christian community for having the Devil inside you
