School Girl JOI

Description: I desperately need an a for my maths course, and i have heard you give the occasional a out if the student 'thinks outside the box'.  having found a dildo cock in your drawer, i decide how i can think outside that box with you.  i offer you a joi, something really special complete with a striptease, all the instructions using your dildo cock and a countdown to cum, before shooting yourself all over my bare bottom.  i think i have earned my a, don't you sir?
