An authority figure in a classroom setup gets played up for taboo power dynamics, with chalkboards, desks, detention, and strict discipline turning into sex. The hookups usually lean into roleplay with an adult student, dirty “extra credit” talk, and a lot of bending someone over furniture while clothes and grading papers get ignored. You will often see glasses, skirts or suits, and plenty of spanking, oral, and fucking framed like a lesson or punishment.
