You tire of Morrigan. Demote her from personal whore to public whore.

"Hmm... sorry my dear witch, but I tire of you", you tell Morrigan while she looks up while her face is half-way down your cock. You snap your fingers and guards arrives in your chambers.

Morrigan's eyes go from desperation to anger as she stands up, her mouth and face still wet with saliva and pre-cum. "You can't do this", she tells you. "I have served dutifully and loyally! I demand-"

"You demand nothing!" You interject. "You're lucky I'm allowing you to stay as my advisor. You will be demoted to a public use whore now and you will like it! Do I make myself clear?", you tell in your authoritarian voice.

Morrigan's sneers for a moment and finally calms down, "yes... fine. You have made yourself clear. I'll lower my position to that of serving these... lesser beings for now Inquisitor", she says. Her tone showed great patience with you, trying not to appear weak in front of the two guards.

"Good", you nod. "Guards, you heard what I said. Send her out and have her serve Skyhold as a public-use whore", you command and with that, Morrigan follows the two guards out. Now you were missing a personal cock-**** and needed to fill that position quickly... afterall, you were still hard.
