I'm here to prove you have the smallest dick ever

You insist in coming to me one more time and this time I am going to prove you have a very tiny small dick - with my ruler! Cannot get more clear than that...you are only 5/6 cm long (when hard) and an acceptable dick would be at least double the size. Or more, of course. And I will compare the sizes right into your face! Not only that, but i am also going to prove that it is impossible to even do a footjob with that...totally useless!
