Succubus Academy

You are John Doe an average 18 year old male, you never exceeded in school, but that's just because nothing ever caught your attention. Well, other than the other students. You were always having intrusive sexual thoughts about people, growing up you thought it was just normal male adolescence, going through puberty, or so you thought.

You receive a letter on your 19th birthday explaining you are a Succubus and you must report to the Succubus Academy. Writing it off as a joke you throw it out and head home. When you get home you instantly feel a weird energy the moment you walk through the door. You walk into the kitchen and see your mom talking with a very attractive woman with horns. You rub your eyes thinking you must be seeing things but they sit you down and explain that your father was an Incubus. He came to your mother in the night and bore her a child.
"I'm sorry I never told you, I just didn't know how to explain." She says apologetically to you while you gather your things into a suitcase. "They told me you would have to go to the Succubus Academy when you came of age, I just didn't know what age they meant. I'm sorry I didn't tell you"

You finish packing your things and leave with her through a portal. It takes your eyes a moment to adjust to the flash of light and suddenly you see before you a giant castle surrounded by lush forests. You assume this is the Succubus Academy you're being **** to go to, but beyond that you have no idea where you are or how to get home. The mysterious horned woman tugs at your shirt for you to follow her, looking around you see several other confused looking people around your age, each being led by a horned individual towards the castle.

You are pulled into a large room with long dining tables filled with people, all watching some sort of ceremony going on at the front of the room.

"Students, I'm glad to welcome you to a new school year here at the Succubus Academy. My name is Headmaster Vlad, and I will be one among many of your instructors during your stay here. You are all expected to live on the premises, you will be split up into different classes, or "houses" as we call them. These are the people you should expect to become your new friends as you will be eating beside them, sleeping near them, and attending all of your classes with them. We use a point system here, both for an individual score and for a house score. At the end of each week, the student with the highest score will be awarded while the student with the lowest score will be severely punished. These points can be awarded or taken away by any staff member for any reason they see fit. That being said, lets begin the sorting process"
