My opinion:
"Dom" is into erotic humiliation. Chantal lied and said she was into BDSM to act cool. It's consentual and she's enjoying every second on the floor mattress. Same with the hard drugs. Chins will say anything if it means being accepted. Acceptance means fitting in which means people want your company and that means attention. If Nader said he was passionate about small engine repair, Chantal would have lied and said she also likes small engines and would have purchased a lawnmower.
Chantal will agree to the usual things done in a Dom/Sub relationship like bondage, spanking, "coercion" of certain sex acts (like anal, gangbang, and/or recording of said acts), verbal abuse, and other paraphilia because she gets off from the attention even if she doesn't enjoy the acts being done to her. She also gets off on Nader being able cum because of her. That's the ultimate form of attention and an ego boost. She must really be desirable for a methed out Egyptian magician to splooge on her face. She's loving every minute they're together.
Nader is into feederism which is tied to humiliation. He gets off on calling her fatty, piggy, making fun of her eating habits, and slapping/squeezing (marking up) her flesh. Feederism isnt just about force feeding their feedees. Chantal is desperate for sex and male attention in any form. So desperate that she will pay money for it. She would sell her soul if it meant she could be smug, the queen Beezer that everyone envies. Take that, Haydurs!!!
We have all speculated over the years that Chantal is very much into public, specifically online, humiliation. Otherwise, she wouldn't continue to do the same cringey and embarrassing shit day after day and still come back for more like the attention whore she is.
I'm loathe to call this abuse. I'm also loathe to compare Chantal to "normal" people because she is very abnormal.
She very much knows what she is doing. I also don't feel as though she is being financially abused. She's willingly accepting the role as sugar momma when her check comes in. She is paying for her attention fix. The drugs are incidental. The kinky sex is incidental. She puts out the cash and Nader puts out her narc supply. It is transactional.
Nader will dump her when her money stops rolling in and she will have buyer's remorse (if she's still alive). Then she will go on to her favorite method of garnering attention: playing the victim. It's not really victim hood so much as buyer's remorse with a substantial blow to her ego and her narcissism.
Poor Chantal. She was taken for a ride. She was fleeced. Her heart broken. Confidence shattered. Arse penetrated, tits slapped. Boo hoo.
If she's still alive and not drooling in a corner, she'll get back her retarded Beezers at that point because she will revert to her tragic self which is what they get off on- A gorl all alone eating buckets of food with her receding hairline recounting idiotic storytimes (maybe now she'll actually have some fresh fodder), while sharting herself with glee.
Don't fall for her manipulation. Not now, not later. If anything Nader is playing her at her own game.
