I had just finished his examination and then just as I told him that he could get dressed I saw that he had a HUGE erection and his stepmother was in the waiting room just next door! And to make the situation worse he told me that unless I showed him my tits he was going to tell his stepmother that I had been teaching how to wank! And then he decided that he wanted ME to do it for him!!! I really didn't have a lot of choice! BIG MILF tits, HUGE hard nipples and GALLONS of spunk!
