I'm your busty teacher Miss Harding, and I caught you cheating on your test! So I threaten to grass you up to the headteacher...that is, unless you do something for me first... See, I've always wanted to stroke your cock, since the day you first signed up for my class, and so I promise to stay quiet about you cheating on your test, as long as you let me give you a handjob right in the middle of my classroom! I stroke your cock nice and hard, whilst dirty talking to you, until you blow a nice big spunky load of cum all over my tits!
