Humiliation of the FMC by MMC or others

Hi folks! I've mostly read books where the FMC and MMC are both victims of their circumstances (eg. human trafficking, dystopian society, kidnapped together). Now looking for something different, where the FMC is humiliated in-person by the MMC or a third party, such as his henchmen or an external villain.

I'd love for this to happen in front of at least one other person, so am not looking for things like making sex tapes. However, being forced to perform sex acts in front of others would be A-OK!

Here are some ideas I've seen in this group that have inspired me:

• She is made to give him a BJ while his men face the wall
• She is forced to submit or is raped or disciplined in front of others
• She is shared by his friends
• She is treated as an object (eg. he carries on a conversation with someone else while fucking her)

I also really enjoy noncon, kidnapping and captive/captor in my Dark Romance.

Thanks in advance for any recs!
