It is Sariel

In the doorframe stands a demoness. She wears leather knee-high boots and a short leather skirt. The black top she wears to cover her chest barely fulfills its purpose and instead draws attention to her cleavage. Her belly is freely exposed, as are her shoulders and most of her breasts. Her hair is as dark as the night and her horns are black and gleaming like obsidian. Her skin is a carmine red and her lips and eyelids are black. From under her skirt a tail as girthy as a human arm appears which thins to the thickness of a dick at the end. It is nearly long enough to reach the ground and is tipped by a clubbed shape. From her back sprout two huge wings. Each of them as tall as her height and if she were to spread them, she’d have a wingspan of three times her own height. She stands there, proud and majestic. Your second in command. The she-devil, Sariel.

“This place is pathetic.” The devil says. “Back in the demon world I had a palace trice the size of this.”
“Welcome, Lady Sariel.” Talith greets the high demon while bowing to her. “You grace us with your presence.”
Sariel quickly looks over the succubus’s wardrobe, then responds by saying, “The fuck are you wearing?”
“Just a little something to tease the nuns here.” Talith replies. “Would you like to try as well?”
Sariel’s face twists into an expression of disgust and says, “I’ll pass.” She then turns to you and asks. “Talking of which, what is your fascination with them anyways?”
You start walking to the she-devil and shrug while saying, “What can I say? I guess have a fondness for mysterious women.”
Once you are face to face with her you say with a much more subdued voice, “Especially when I can seduce then away from their righteous path and into corruption.”
Sariel cocks her head and looks at you with interest.
“Corrupt how?” She asks with her voice at the volume as low as yours.
“Basically, I expose them to the cardinal sins one at a time.” You explain. “I’ve already tried gluttony and lust to great success, leaving two of them half demonic.”
“I see.” Sariel says as her eyes turn to the left and right, studying the posters you put up. “I take it these decorations are your handiwork then?”
Rather than say anything, you just grinned at her.
“I’m getting intrigued now.” Sariel says as she crosses her arms in front of her bountiful chest. “And they let you corrupt them like that?”
“Oh, that’s the beauty of it.” You reply. “They think it’s just a bit of sex. Nothing major, right? They are simply not aware allowing me to break their purity results in permanent corruption.”
This got Sariel to chuckle.
“Humans.” She says mockingly. “They are quite idiotic. Aren’t they? Is that also the reason we speak so softly?”
“Aye,” You reply. “They are permitted to roam around free. Wouldn’t want them overhearing our plans for leading them into sin now, would we.”

While talking to Sariel about the nuns, the demoness suddenly leans to the side and looks at something behind you.
“Speak of the devil.” Sariel says.
You look behind your shoulder and see both Jennifer and Angelica standing there. The two nuns are staring back at Sariel until Jennifer rolls her eyes and says, “Ugh, another demon?”
You were just about ready to groan at Jennifer’s reaction. The brunette nun really should not have said that. High demons are notorious for demanding respect from what they consider to be lesser lifeforms. Since your father is a high demon like herself, Sariel started with a certain level of tolerance for you. After you permanently brought her into the human world, she decided to treat you nearly as an equal. Hence why you are permitted to be so casual with her. Jennifer however does not enjoy that same level of treatment from Sariel. Though knowing Sariel, she’ll be quick to put Jennifer in her place.

Sariel gets down on one knee and places both her hands on the floor, like she’s about to start a dash. At the same time, she spreads her dark leathery wings upward. Luckily for her, the lobby has got a pretty high roof. Then Sariel both jumps and flaps her wings down at the same time, launching herself up and forward towards Jennifer. She bridges the distance between the two of them with one jump. After she lands Sariel brings her left hand to Jennifer’s throat and lifts the young nun off the ground. Jennifer quickly grabs Sariel’s wrist with both hands as her feet search for the ground.
“Who is this insolent little brat?” Sariel asks as she bares her teeth at the frightened Jennifer.
“Please forgive her, lady Sariel.” You reply. “The nuns here have simply not been taught how to properly address a woman of your standing.”
Sariel looks over her shoulder and then asks you, “Whose fault is that?”
“It was my decision to put it off for so long.” You say. “If anything, the blame should fall on me.”
Sariel turns her attention back to Jennifer and says, “Then make sure you teach her quickly.”
Then Sariel drops Jennifer to the ground. The young nun falls on her butt and immediately crawls backward, making a distance between her and the intimidating she-devil. Angelica quickly comes to Jennifer’s support. For a moment, Sariel looks down at the albino nun. Then she retracts her wings and walks away.
“I will stay here for a while.” She announces. “Make sure I get the best room. In the meantime, I shall survey this place. When I’m done, I shall inform you of my judgement.”

Jennifer stays on the ground, staring at the departing Sariel until she is out of sight. Then she stands up and asks, “What the hell was her problem?”
“Jennifer. Language.” Angelica admonishes her fellow nun.
“That was Sariel.” You explain. “My second in command and a she-devil.”
“Wait until I see her next time.” Jennifer grumbles.
Assuming that Jennifer is planning something stupid you give her a strict look and say, “High demons like Sariel may be notoriously arrogant, but they also have the power to back it up. Honestly, I feel you should consider yourself lucky she didn’t use any of her demon-magic to burn you or worse.”
“So what? We’re just gona let her do as she pleases?” Jennifer complains.
“High demons see themselves as the kings and queens of the demon world.” Talith explains. “As such, they will conduct themselves in a regal manner and demand to be treated like royalty.”
“Great.” Jennifer complains. “Now we got a god damned drama queen to deal with. I’m gona tell Siara.”

Jennifer and Angelica then both head towards Siara’s room, expecting to find their abbess there. As the nuns are leaving, you tell Talith to go after them. In case they come across Sariel again. In the meantime, you gather a couple of imp maids and take them with you to your lair. It’s the most luxurious room in the nunnery so Sariel is going to want to sleep in it.

When you get to your room you notice Siara and the five demons you sent in with her are gone. But though they are absent, the scent of sex is heavily present. You check if Siara got into any of the side rooms and are pleased to find out she didn’t. You unlock the side rooms, order the maids to clean up the main room, perfume up the place and definitely replace the sheets with fresh ones. After having given the maids their orders it is about time for dinner, so you head out to the refectory.
