Hyper jealous possessive girl( yandere)

I've been wanting to do this sort of scene again for a while now. I am not picky on kinks and will not get scared off by anything. My own kinks vary by how I'm feeling at the moment though I will discuss anything that I want to put in the role play. I like to write out about 10 lines per post minimum and expect the same in return 90% of the time. I enjoy smut but also enjoy buildup and story thrown in around the smut like a sandwich. I prefer to roleplay via pm and messenger. I'm not asking for your character to be dom in this,but she should go out of her way to get what she wants,such as using black mail or ruining someone's life to get her way. One idea I have for this is a teacher/student scene where the teacher(me) takes advantage of the girl and takes her virginity. The girl then becomes super clingy to the guy(the teacher only thought it would be a one time deal). This is but one example and I'm open to other ways to go about a scene such as this.
