I dont see what he says as red flag
But him just being highly amused by the fact how much he trusted him ?
I know that puts him in a higher position where he can hurt him but I just think what he is saying now is just him feeling the actual meaning of being a dom in bdsm and accepting their relationship as it is (not like how it was at first and "oh so you wanna be fucked so I'll do you but I dont like it")
Just meet alreadyy shake hands kiss kiss and run that mf company like two power bottoms together
