memory of the first time I saw a real penis

欧米かー

よくわからんが
12歳で13歳の子とエッチしたってことかな？

How can you say it was huge if it was the first time to see a penis?

It was the first time I saw a real guy's penis.
(I had seen several times in some movies or pornographic magazines whose length were about 5inches or 6inches.)

At that time, his penis was over 9 inches or so.
I'd never seen that,so I terrified that.
But I certainly got turned on,too.
