Cupcake SinClair - Duped In Detention

Poor teacher's pet SinClair! What she thought was a chance to TA for after school detention to get extra credit...was really just a plot for you to get her alone! She never thought her professor would be capable of this, but now she's duct taped to the chair, moaning helplessly behind her gag as you stare at her heaving breasts and struggling body. What will you do to her next?
