Biology Lesson

You are almost at the top of my class thanks to staying after school on so many afternoons.  You are addicted to me, your hot seductive teacher.  There is one new form of worship you need to learn though, in order to show your devotion which comes down to simply consuming my biological waste.  Watch me shoot a massive stream through my panties and clean my ass.  Open your mouth wide and clean it all up including the puddle on the ground. Suck my panties until they are completely dry.  We will keep meeting after class like this to keep up your grades.
