Three girls are discussing penis size and the fact that they don't believe there are actually any really small ones in the world. Just then Bob walks in having had a swim and the girls notice that he doesn't have much of a bulge at the front of his shorts. They ask him it was cold out there and giggle and then decide to see if Bob has a small penis. They start pulling his shorts down and soon come face to face with their first small penis. The initial shock soon gives way to laughter and the girls quickly fetch a tape measure so they can check exactly how small it is. When it only reaches two inches on the ruler they wonder if it gets any bigger and start wanking it. They strip off and show him their gorgeous young bodies to give him some encouragement but the pathetic penis doesn't get much bigger and the girls humiliate him before sending him packing!
