They accept, but reluctantly

The nuns first don’t want to join you at the table. However, it’s late in the afternoon. Hours since they last had something to eat. Miryam is the first to give in and take a seat at the table, though she does so furthest away from you. Then the other sisters begrudgingly accept. As the nuns take their seats one by one, you are pleased to see Angelica ends up taking the seat closest to yours. They start by making a prayer and thank their god for the food, then they start eating. During the meal, you notice Angelica only partakes in bread, cheese, pasta and other vegetarian products. The others are less choosy about their food, with Myriam apparently having a fondness for meat as she wolfs down some ribs and chicken legs.

“So, with me being the new duke of this province I have decided this nunnery belongs to me now. As such there are going to be some changes here.” You explain to your guests over dinner. “We will start by constructing of a new residential wing. Fear not, we will not destroy any of the existing buildings. Instead this nunnery will be expanded. The surrounded residences are still destroyed from the war anyways, so it’s not like anyone will be complaining about losing their homes.”
“Will we be **** to live there amongst in between your demons?” Siara asks.
“You will find that I am a kind warden. There will be bitter few things that will be **** onto you, if any. You will be permitted to live and sleep wherever you choose to do so.” You tell her. “The old residence, the new residence, … if you wish it, you can even live in the chapel if you so desire.”
Siara nods approvingly and says, “That is very generous of you.”
“About the chapel.” Angelica speaks up. “Can you promise us that you will not make any changes to it?”
One of the flights of inspiration you had before returning was to take the statues and paintings from the chapel and replace them pornography. Statues of nude women, naked men with erect dicks, of them both posing and in the middle of masturbation. Paintings depicting the beauty of human nudity. Of men, women and demons engaging in sexual intercourse. If Angelica had not asked her question, you would not have to make any promises and could do whatever you wanted. But since she asked, you can now either deny her request or allow it. The former will motivate all the members of this convent to resist you more. Which is the opposite of what you want them to do. The latter however will have them lower their defenses, making it easier for them to trust you. This is where your demonic wits come into play and you offer them a bargain.
“Don’t chapels need to be adjusted every once in a while? Like, for the holidays for example?” You ask Angelica. “I mean, when you perform a Christmas ceremony the chapel is decorated differently than it is for an Easter celebration, is it not?”
“True.” Angelica admits. “But when that time comes, I feel all of us would be more comfortable if we get to decorate the chapel ourselves.”
“I fully agree with Angelica.” The abbes replies.
“Me too.” Jennifer adds.
Miryam quickly swallows a piece of chicken and says, “Same here.”
You then feign defeat, offer Angelica a gentle smile and say, “Very well. When it comes to the chapel, only the four of you will be permitted to make adjustments.”
With that, the nuns have been placated and you have your wiggle room. The dinner then continued with you informing them about all the changes that are going to happen and the sisters accepted them. Though be it under protest.

After desert, the pious women decide to head to their chapel for their evening prayer. A few imps dressed as maids and butlers come along to clean up the leftovers. They are lesser demons with a body type similar to that of petite humans. The only traits distinguishing them as demons are light blue skin, two small horns on their forehead and a pointed tail coming from their tailbone. This leaves you free to engage with your subordinates.
