Your teacher asks you (Dan) to stay after class because she sees you touching yourself during class and gives you a detention. During detention you pull your cock out and start playing with yourself, not caring if she sees. When she notices she is very mad but ends on and makes you sit down so that she can give you a hand job and a blowjob. After a while she realizes that you are staring at her smartwatch and that not only are you a pervert, but you also have a smartwatch fetish. She continues jerking you off so that you can see her smartwatch and gives you a cum countdown to cum all over her face.
