Funny Story

So me and my little brother have always been close and I like to think he talks to me about everything. He's 13 (I'm 16) and he is taking sex Ed in school and he came to me today and said that he felt he was ready to have sex but he keeps looking down at his dick and he doesn't see the condom growing and he asked me when he's supposed to start growing one so that he can have sex. I tried my best to keep from laughing so I wouldn't embarrass him and I then explained everything to him and we had a good laugh about it. I just thought this was funny and thought I would share it with you ladies.
