Two college girls are in trouble for failing their human biology class. Their teacher is at his wits end and decides to show them the real thing to get them to understand the male genitalia. As he unzips his trousers the girls look on in shock as they see their first penis! Shock soon turns to curiosity though and the girls edge closer and start feeling the cock which soon stiffens. They take turns to suck it and are amazed when it shoots white stuff all over Kirsty's face!
