Just for clarification, when you say "bully/manipulate" do you mean the soft-version? (bullying as in yelling, scolding, etc until the seme cries but never anything to the point of being considered abusive) Or do you mean ALL IN? to the point the uke could be arrested?
I'm not sure if I know anything extreme, but for the soft-version I'd recommend Missing Pepper Case ( https://www.mangago.me/read-manga/missing_pepper_case/)
For extreme I'd maybe say Ignite The Dawn ( https://www.mangago.me/read-manga/pearl_boy_ignite_the_dawn_dindinxlightsaberkunn/) based on the earlier chapters, though I'm not very sure if the plot stays consistent since I've been letting it marinate for the past few months.
For VERY extreme id recommend Reverse Thinking ( https://www.mangago.me/read-manga/reverse_thinking/) though for a heads-up, the toxic one is only "uke-looking" but when it comes to physical relationship he's still the penetrator, just in case you were talking about positions instead of appearance.
Mobius strip might count.
