My Brother's Big Problem

Me and my kid brother were close. For discretion I will say his name is John. I was one year older. John always had a problem that really came to light about the time we hit middle school. His penis was very large, I mean unusually large. In a small house I ran into my brother and father naked a few times. John was bigger than our father when he was 12 years old. John got teased by the other guys and avoided the locker room, showers and sports.
In our teen years word got out around school and many girls wanted to find out for themselves. It only made things worse. john was too big and the girls couldn't take it. He was frustrated at having to stop all the time because it hurt the girl. Not to mention the one time a 16 year old girl had to go to the doctor the next day and explain to her parents what happened.
His senior year we were at a party. A friend of mine had her cousin there, she lived in a neighboring town. She was a tiny, skinny girl. 4-10 and maybe 90 pounds. When I wasn't in earshot I noticed the girls talking to her and pointing to my brother. It was obvious they were talking about his penis. I had seen it a million times.
Later that night John vanished. I was ready to go home but couldn't find him. Then my friend told me her cousin talked him into going upstairs. I panicked, I thought he would kill her! Boy did I get a surprise. When he finally surfaced he was on cloud 9! John was so excited he couldn't wait to tell me. He was pretty graphic and apparently not only did she take it, she took it all and begged for more!
They dated from that point on. Got married and are very happy.
