Charlie wants to know why you haven't finished your assignment, she knows you are usually good at your college work so she knows you are not concentrating properly! You tell Charlie you are getting distracted by what she wears, you can see straight down her top at her perky tits. Charlie decides to be lenient on you and decides the best way to help you is to let you look at her tits while you pull your dick out and have a long hard wank.
