I love coming up with this kind of fantasies/scenarios in my mind. It makes situation so much more fun <3
In Morrowind I used to have a sexy female warrior who was wearing revealing, but still heroic outfit.
One of her missions was going to Caldera to find three female dancers, who (as I had imagined it) were involved in some illegal drug dealing activity and needed to be brough to justice. These dancers were not armed as the heroine, but they were surpricingly good in fist fighting. Three of them managed to outnumber and beat the armed heroine with their bare fists. I imagined that after beating her and laughing to her, they stripped off all her gear, weapons and money, captured her and sold to some dirty fat lord for his perverse amusements. Later the heroine would manage to find a way to sneak out and escape from the fat lord's mansion, wearing some slave/stripper/whore outfit that she was forced to wear there. She would go to revenge to the dancers and challenge them to fight again, only to get beaten up even worse than in first time. Then the dancers would send a word to the fat lord that they have captured his escaped slave, and collect a big bounty for doing so. After getting captured again, the heroine would be locked up good this time, and watched carefully so that she would never get another chance to escape from her terrible fate. Meanwhile the dancers involved in criminal activity would have fun time with all the money they have got from selling the heroine and her gear and from collecting the bounty they got from capturing her.
Another favourite setting is wrestling ring because there is plenty of audience and usually TV cameras to capture the event.
I always loved to think that Reiko Hinomoto (in Rumble Roses) had been beaten in match so many times, that she had became a complete jobber: she had become a joke that one would take seriously and nobody would bet money for her to win a match. Her fame and career as a professional wrestler was ruined, and she was only allowed to continue because the audience loved to come to watch her lose baddly to other Roses. Other Roses would taunt her and have their way with her, and audience would only come to see her lose like bitch and take pics of her, hoping to get a good picture of her in some humiliating and revealing/sexy position that they could watch later for their perverse desires.
In superheroine setting, I love the idea that the superheroine is defeated and captured, and then the villains take out a camera and record while some of them rape the heroine, or just simply just show her chained and captured, maybe sobbing and her costume badly damaged in fight. Then they sell the tape to television and demand big ransoms for releasing the captured superheroine. Soon the TV would broadcast this tape in news, and all newspapers/media would spread the news that their once proud heroine was kidnapped and raped like a normal woman. City would have to pay the big ransoms for the thugs to spare pitiful superheroine of her fate, but her career as a heroine would be finished. Nobody would take her the heroine seriously anymore or idolize her for her strength. In the end she would give up being a superheroine, abandon her costume, and start living life as a common woman.
