Climax Duel: Sex Battles with Magical Cards

Iwasaki, who is consistently despised for having the single worst personality in school, picked up a mysterious gold coin — which turns out to be an invitation for the magic card battle "Zecchou (Climax) Duel". The rules are simple. Trick cards, trap cards and mini-game cards are all freely allowed. If you can make your opponent climax first before you do, you win. If you lose, your cards will be forfeited and you have no choice but to become the winner's obedient servant. This is a game where one must also rely on luck being on your side and not just on techniques to win, can you outlast your opponents? (Source: FANZA)
