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?
