You play as a young muscular young man who moves to a new house on the tropical island of Vera-Bosti with his mother and sister. There you are challenged by a local school bully to a duel: the one who fucks the most girls in a week will be the winner. Your goal is for each girl to achieve "Epic Lust" so that she is available for conquest before your challenger gets into her panties. And, consequently, the epic "Battle for the Bulges" begins.

You live in Mistbury, at first glance, an ordinary city where you live an outwardly normal life with your family. You'll need to study hard if you want to pass your final exams, but it won't be an easy path because you'll soon find out that things aren't what they seem, and things can heat up fast enough...

The day that everyone feared, the day that everyone hoped would never come, came in the form of a nuclear explosion. Government shelters built to save and protect the lives of their citizens soon collapsed from overpopulation and food shortages.
Having no other choice, many tried to find another life by returning to the surface. Unfortunately for them, they traded a slow death from starvation for a painful death from radiation. It was the only option for those who still survived... but not for you.
