CS: This post is so interesting, because this has happened to me a couple of times. I guess they were kind of embarrassing experiences. The first time happened accidently. I was 16 and was over at my girlfriend's house, we went upstairs to go into her bedroom. The door to her little brother's room (jason) was open and we saw him masterbating. He was only 13 and a half, but his dick was really big. I would guess 8 inches long or more. I just remember thinking that he could have fit two hands on the shaft and the head would have still been left. He was also thicker than his own wrists, which were already thicker than my girlfriend's. He didn't see us. The embarassing part was actualy a few days later when she saw my penis erect for the first time. I figured that she wouldn't notice the difference, because we only caught a split second glimpse at her borther's penis. We layed down on her bed and she stroked me (in a very jerky, inexperienced way, so I had a hard time staying hard) then she said, "If I keep stroking it will it just keep getting bigger?" I said, "Yes, but it only gets so big, then it stops growing. I'll let you know when it stops." Then she asked me this, "Jason is only 13, so you must get a lot bigger than him right? He looked about twice as big as you are right now, (she saw that I looked worried and tried to boost my ego) but if I keep doing this, then you'll probably be three times as big as him." After that I couldn't get an erection at all because I was too nervous, it just kept shrinking and she just can't tugging on it like she was playing tug of war with a puppy.
I have another story and some more tid bits about her comments about her brother, but I'll save that for another time. Thanks for the outlet.
