Yasmin Grayce "Fashion Show"

Yasmin has been asked to take part in the college fashion show and she has been given the job of modelling some lingerie, she has been given a few different pairs but doesn't know which one looks best so she wants to know if you will help her decide. As one of the college tutors it would be inappropriate to see her getting changed but you know you won't get a chance like this again so you agree to help her choose. Yasmin starts stripping off and you can feel your dick straining against your trousers and you know it's only a matter of time before you pull it out and start wanking in front of her.
