Melissa is waiting to discuss her studies when she is joined by trouble maker Helen, who has been sent to Headmistress for misbehaving again. As they both wait for Headmistress Helen suggests that maybe she could teach Melissa some more useful things and unwittingly Melissa agrees! Helen asks Melissa about her sexual conquests and when she goes quiet Helen says she will give her a lesson in sexual positions so that when the time comes Melissa will know what she is doing. As Helen makes her way through the sexual positions she knows she starts to undress Melissa & herself explaining how you tend not to have sex clothed (most the time). As both girls make their way suggestively through the Karma Sutra they lose more of their uniforms and soon they are both naked as Helen pretends to shag Melissa over the desk!
