While giving a blowjob is generally submissive there are ways the roles can be reversed. For one, she can threaten to use her teeth if he doesn't do something humiliating when she's milking him. Another way could be if she has him bound and starts draining his soul "Straight from the tap" against his will.
Your first example with the teeth might somewhat qualify, but the second one with the "soul draining" still doesn't stir any submissive feelings in me, it rather sounds to me like a narrative excuse given for receiving a blowjob. I even saw some maledom games with this misunderstood "succubus" trope.
Succubi have nothing to do with "succ"-ing, but given the similarity with English dick-tionary, it was enough to create a truckload of games where the fiercely independent and dominant daughters of Lilith are used as cock-sleeves. In "reality" succubi should be dominating the MC, make the MC lick them to orgasm to gain psychological energy and pleasure, not give pleasure to the MC, while supposedly they receive some ethereal power. The sexual act itself seen from without would still look like a submissive woman servicing a male. Instead the succubus could gain the same ethereal power by forcing the MC to do visibly submissive things for her, after all the lore is entirely in our hands to craft to be more in line with both what succubi are mythology-wise supposed to be and with femdom. Therefore, I am mildly convinced that the "succ" misunderstanding which played into the hands of the non-femdom crowd, turned one of the very few dominant female archetypes into yet another whore archetype, which is a shame.

But hey, don't let me stand in the way of what makes sense for you. Its just that in my case, I like my femdom in such a way in which it is clear that the female is in charge and where the male genitalia is not the focus of actions.
