Yuusha Auction

The female hero Luludi is kidnapped and put up for auction. The one who wins the bid for her with a huge sum of money is a nobleman who is a "hero collector." "A female hero's virginity...how precious!" Unable to use her full power due to magic, Luludi is defiled, raped, and has her dignity trampled upon. (Normally I would never lose to a man like this...) Given only pleasure, her body is transformed into an obedient sex slave that will do only what the man says...
