Katie T "Miss Big Tits"

Katie is not happy that you have detention with her for the fourth time this month she tells you to get on with your work while she does her marking. When she looks up she notices that your hand is under the table and in your trousers! It soon becomes clear why you are always in detention so Katie has an idea, she lets you wank over her tits to get it out of your system and tells you she doesn't want to see you in detention again!
