idea breeders arena
you could add shirts and even traits based on your rank
the idea of the arena is 10 battlers enter this would be a underworld thing the students do because their horny
the winnings would be whatever could be pooled for a prize meaning the prize is random
you would be placed in a mines area that was long abandoned you would then search thru for each battler and have to breed them your goal is to make them cum before you do
cumming inside a duel is a loss
but outside of a duel you can sat yourself
you could also get attacked mid masterbaiting to make the duel even harder so you would need to find a safe area to do it
