This is very interesting! Let me ask you a few questions and add my thoughts:

1. Are you physically stronger/taller than her father? I think it would certainly help a lot, although the bullying should be more psychological of course, it would definitely make it easier if the dad feels like he can’t retaliate at all, even on a physical level.

2. Is the daughter on board with it or at least open to the idea of ‘teasing’ her dad? I think this is a deciding factor on how obvious you can be in your approach. If you got her on your side or even enjoying it, you can be a lot more in his face and have her participate (dressing slutty in front of him, making out with you, dropping mean comments). Also, maybe even more importantly, she could play a crucial role in basically gaslighting him, telling him that he is being clingy or overly protective, making him question if he is the one doing something wrong etc.

3. Do they live together? Of course, this determines how frequently you see him/he is around, and therefore how much of a subliminal step-by-step approach you can take. For example, if you’re around him on a very regular basis, you can slowly ease him AND his daughter in a new dynamic little by little. It will be easier and more comfortable for the daughter, and the dad will be more likely to accept things and just take the bullying as things slowly unfold. Also it will be much easier for the daughter (or you) to gaslight him this way, there won’t be any sudden drastic changes he can point to, but only small, subtle hints that you can brush off as him being overly dramatic.

4. Do they fight sometimes? In case the daughter isn’t aware or open of your plan, I think this would be the best way to make her cooperate. Capitalize on her being angry at her dad, on her being open to hurting him, being mean to him. Fucking her right after she’s had a fight with her dad would be the best way to get her to enjoy teasing him, talking shit about him, being mean to him - and connecting it to sexual pleasure. Making her be extra loud during sex so her “asshole” dad can hear and feel uncomfortable, making her realise that her sexuality is a powerful tool to keep her dad in check. If necessary, I think you should probably even go as far as gaslighting HER a bit and trying to create fights between dad and daughter. Making her feel hostile towards him would be a huge benefit.

5. Does she call you “daddy” during sex? This would be an amazing way of claiming your position in the family. It shows your dominance over her, it shows her acceptance of your dominance over her and most importantly, if you can get her father to overhear his little girl calling you that, it would be an immense shock, humiliation and embarrassment for him. Hearing his daughter call another man “daddy” (in his own home) while getting fucked and her later stepping out of her room with messy hair, a flushed face, skimpy clothes and maybe some traces of cum on her and smiling to him, as if nothing happened - it would definitely mess with his mind. A lot.

Lastly, just out of interest, could you provide a pic of the daughter or even of her AND her father? Would love to see what you are dealing with here.

Also what kind of “bullying” have you done so far? Would love to hear some stories.

Well, it any case, I hope my thoughts were helpful and I wish you good luck!

1. Yes. I’m 6’3 and I am so much bigger than him. There is no way he could physically overpower me

2. The daughter is on board.

3.yes. She lives with her dad

4.they don’t really fight.

5. Yes. She always calls me daddy and she’s very loud in bed.

When it's just you and him, or just you him and your gf, treat him like shit. Be rude, ignore him, put your feet up, change the channel when he's watching tv, strut around the house half naked and encourage your gf to do the same, make out with / fondle / grope her right in front of him, etc. When her mom or other relatives / friends are around, do the opposite. Be Prince Charming to them. Be super respectful, listen closely when they're talking, make them laugh, etc. That way, when you continue to bully him, no one will listen to him. They'll probably even write him off as just being a clingy dad.

I’m definitely gonna try that
