Grassing Him up

The teachers have heard some troubling rumours that their male colleague has been heard masturbating in the toilets. They call him in and he admits that he accidentally took some viagra before coming to work and now he can't get his cock to go down! The ladies order him to drop his trousers to check he's not lying and a throbbing boner springs out! They enlist the help of student Charlotte and decide to give him some relief. They take turns to wank and suck him off until he shoots a big cum load into the air for them!
