Shy girl Dava has been called in to do a survey but has no idea what it's about. Rob explains that he is measuring girls' reactions to naked men. Other than seeing her brother in the shower once, Dava is very inexperienced and looks on in shock as Rob starts stripping off. She can almost not look when his cock pops out but he soon encourages her to take a closer look and even to have a feel of it. As he teaches her to give a handjob her head gets ever nearer until his cock slips between her lips and she gives him an amazing blowjob until he spunks on her bookworm glasses!
