You are an average person living a life of an average trainee. After one more one stressful day of examining you are sitting at the average train station waiting on the train to get you home. Just one yawn... and things stop being average! You get up in the the other world full of magic, warriors and attractive looking nekogirls who believe that you were selected by their goddess! This function includes a great deal of wonderful bonus offers so don't be in a rush to decline it...
I think something like this in real life would be pretty interesting. Imagine that you might stick your dick inside a hole and some girl would suck it dry. This is what our heroine do to earn some money.
