I was more thinking the opposite tbh.
A scene where Mezz isn't drugged, but has been defeated and therefore trained so many times that the barrier between his hypnotized self and his regular self is very thin. So in his lucid state he asks Mahir, of his own will, to put his Hyena cock up his ass.
Because lucid Mezz must be able to tell what's happening at least a little. And it's scary to not know...but there's also a part of him that wants to know what it's actually like. Like...there's gotta be a reason why drugged up Mezz wants it so bad. So in a moment of vulnerability or being unsure in himself, he asks the only person who knows how he's conditioned (and therefore maybe knows how not to put him into the drugged up state) to, let's say "let him know what it's like".
Part of my mental image is: after asking Mahir pulls out the clicker to put Mezz into that state because they don't entirely get what the bunny is asking for her and Mezz goes "No wait! Not with that."
And after that the full implication of what Mezz wants sinks in and once they understand they begin teasing Mezz about it.
