You have been kept in the basement for several weeks now, being used by the geeks to figure out how to increase the intensity of male ******, which is all to make more money for St Mackenzie’s. However lately when you have been made to jerk off you have orgasmed but nothing has come out, no ********* at all. So the Geeks have handed it over to Headmistress to try to get a sample and, knowing you are a breast pervert, she has brought Miss Lee with her. They make you drop your trousers and you start to jerk your **** while they to tease you. They make you ****** very quickly but all that does is prove is that there is no ***. They slip off some clothing and try again but still nothing, even with an ******. Finally, with Miss in just her stockings and heels and Headmistress in just her lingerie and unbuttoned blouse they try a last-ditch attempt. With Miss bouncing he massive **** in your face and Headmistress grabbing hold of you, jerking your **** hard and fast, will they get the sample they need?
