Little sister, is my cock big or small?

The boy has a doubt existence and asks his little sister: IS MY VERGA BIG OR SMALL?!. And I say, we have all asked ourselves that question in our beginnings, who better than your own sister to solve the question, the opinion of a woman is what leaves one calm in these cases. Total that lowers the underwear and shows the cock to her sister, she stays with her mouth open, first only looks at her, but then touches her - I BELIEVE THAT TO BE ABLE TO SAY I SHOULD SEE HIM ERECT - and as he says this he puts it in the mouth, what else will happen between these little brothers?
