Four years earlier
Bree was struggling with the ties on her panties. They were black, lacey, and did nothing to leave her decent, not that it mattered in Hell. As her fingers carefully secured the knot, the pressure undid the strings on the other side of her hips, as they had done two times previously. The bra for this set of lingerie was already on, but not without an equal amount of issue. Looking around the classroom that looked almost identical to the images shown of mortal universities, Bree could see that all the other students had already gone home, dressed in their scarce undergarments as per the assignment. When the knot loosened for the fourth time, Bree grunted, tossed the panties aside, and plopped back down into her seat.
"Ugh, why do mortals wear this? It's impossible to even get on."
Professor Laezynnarus walked over with a smile, She was dressed in her normal garb, being a black cardigan over a red shirt that contrasted in a satisfying way with her dark purple skin. Her long, long legs that gave her the six-foot frame were on display from her black skirt that came just below her knees, and obviously held no intention for physical attraction. As with any succubi, the clothing still somehow managed to conform and fit just perfectly to the Professor's figure, accentuating her proportioned breasts and slim waist.
"Breetheolamus, mortals often idolise form over function. It does not matter how easy something is to create or maintain, as long as it looks nice. In the case of many types of lingerie, the same is true."
"I get that it looks sexy, but this bra is so uncomfortable. I couldn't wear this for three minutes, much less three days. What kind of assignment is this?"
The professor laughed. "As a succubus, you are going to need to get used to wearing the kinds of clothing most mortals find sexually attractive. You are going to be wearing them often when you start your job next month, so it is better to get acquainted with them now."
Professor Laezynnarus bent over and picked up the discarded panties, allowing the skirt to naturally draw attention to her shapely rear. She twisted her neck slightly as she stood to avoid catching one of her horns on Bree's desk. Her horns were long but slim, emerging about an inch and a half above her eyes and turning sharply backwards, following the edge of her skull like a pair of black-ivory mohawks. Towards the back of her head, they turned again and allowed the remaining half-inch to taper to a sharpened point that pointed to the ceiling. The black bone was shiny and polished, and Bree had to keep from bringing a hand to her own head in an attempt to feel if her horns were developing yet, despite knowing they weren't.
"Breetheolamus, why aren't you applying yourself?" She passed Bree the panties, which the student accepted with a grumble.
"I've been trying to put on this underwear for twenty minutes and you think I'm not applying myself?"
The professor sighed. "You know what I mean. You are putting in the effort, but you aren't actually trying to succeed. You work as if there is no goal. You are trying to pass this class, but not to help your future as a member of A.F.A.."
Bree slumped forward onto the desk, resting her chin in the crux of her elbows. "It just... Doesn't it feel weird? Existing for a singular purpose defined specifically by what you are? Like, I get it- I'm a succubus. I'm good at sex stuff. I really like sex stuff. But is that everything? Why can't I choose to work for Satan in the Wrath department?"
The professor pulled over an empty seat beside Bree and sat.
"I know it doesn't seem very fair, but that is just the way it is. We are greater than mortals in every way, except for one. There is one singular facet of a mortal's life that we as demons lack- the ability to go against our nature. A mortal born in any country, under any lifestyle, can become anything they might desire. Aside from obvious limitations of course. An evil child who faced nothing but hardship and abuse still has the capacity to become kind and benevolent as they grow older. In the same vein, a lovely child who experienced only kindness can age to provide the most wrath and hate."
Professor Laezynnarus rested a hand on Bree's shoulder.
"However, we demons are more restricted. Perhaps a curse bestowed by the ones above, but we possess no such luxury of choice. We cannot go against our nature. We simply cannot even comprehend such an act, and for the few that can, the committing of the act is impossible. We are succubi, and that means we can only be demons of lust and sex- nothing more, and nothing less. In the same way that a mortal's heart beats without their control, the need for sex and intimacy acts beyond our intentions. Take these wishes of yours- you wish to work as something else, but even you cannot comprehend existing as anything other than a succubus. Wherever your desires tread, sex inevitably follows."
"But why does that have to stop me?"
This brought a sad smile from the professor. "Because the other departments simply cannot provide for beings like us. Lust is necessary to our survival. The other departments simply have no way to provide it. We have the souls of sexual torment here to feed from, but they only exist here. It is simple, if we work somewhere else, we will fade- cease to exist entirely."
Bree breathed for several moments. "At least the students of wrath don't have to wear this stupid lingerie. Blood is disgusting, but is probably much more comfortable."
Professor Laezynnarus chuckled. "Perhaps. You should give A.F.A. a chance, Breetheolamus. You have the potential to be a great succubus- once you get the proper motivation that is. Each of us have our own unique abilities, but yours may very well be one of the most useful for a succubus that I have ever seen in all my centuries of teaching."
Bree blushed, the pink of her cheeks darkening to a purple almost the same shade as the professor. Despite being nude from the waist down, Bree felt comfortable next to the professor. With the professor, there was no judgement- only helpful advice. "S'not that useful. Pratillerum can give his partner endless stamina- that's much better."
"I wouldn't say so. All succubi connect to the Lust and pleasure of those around them, but your ability brings that to an entirely new level. Not only do you experience the Lust around you much more profoundly, but it extends beyond Lust to other emotions. You can feel joy, sadness, rage. You can look beyond their sensation and directly into their mind. You think what they think. You see what they see. Hear what they hear, feel what they feel. You are able to connect to others in a way that no other succubus can, and a connection like that may be the single most powerful tool of any succubus. You could understand exactly what it is that your partner desires, and use your other abilities to become that very wish."
"You make that sound like it would be easy."
"It isn't, child. It never is. Out of all of the sins, Lust is the most difficult to obtain."
Bree looked up and locked her amber eyes with the pale greens of the professor. "Really?"
She nodded. "Indeed. We succubi and incubi have to work the hardest out of any of the collection demons. Mortals tend to lean toward acts of war, they always have. As much as they can change their nature, the one thing that always lies dormant and reay is their sense of violence. When they get angry, they want to break things. They want to hurt people. That makes Wrath very easy to obtain."
The professor reached a hand up and closed it around an object that materialised into her grasp. Bree recognized the object from the previous lessons as a standard U.S. dollar bill.
"Greed is even easier. Not everyone is greedy, but the ones who are have far more than enough for the collection demons to siphon. Mortals who have an abundance of something almost always want more- more than anyone else. They want to be the wealthiest person alive. They don't care about the needs of others, just their own desires. The more they collect, the more their Greed grows, and the more that Mammon Enterprise takes. The other companies are no different."
"What makes Lust so difficult?" Bree questioned.
