A few years ago I was visiting my cousin. A hot girl but like a sister to me so I never looked at her like that.
One night was very warm so we slept in our underwear with a fan on. She on her bed and I on her couch in a small studio apartment.
The next morning I awoke with a raging hard on and it was very tight in my boxers so I just slipped it out the fly and went back to sleep.
A bit later I heard some noise and slowly came out of a REM cycle. I could still feel my hard on and now I was laying on my back with my cock sticking straight up and I realized that if my cousin awoke she could see it. I was a bit mortified as to what to do so I just opened my eyes enough to take a peak and see if she was up.
Sure enough she was and she was staring at my hard cock. Every once and awhile she was making a noise and I couldn't figure out what the noise was. I opened my eyes a little more and now I could see, she was laying on her side with her head propped up with one arm and the other hand was buried in her crotch and moving rhythmically. She was jilling her pussy.
I didn't have the heart to roll over and stop the show for her so I just watched all the while, my dick feeling like it was going to burst.
Pretty soon she did a little shaking so she had to have orgasmed. She then sat up quietly and took a better look at my cock before lying down and going back to sleep.
That was early morning just after dawn, about an hour later I awoke again to her stirring and asked how she slept. We talked a little bit before getting up to shower and eat.
Way later she was talking to some friends and I overheard her say that I had a really big cock and they should ask to see it. A few days later one of the gals told me my cousin said I had a big dick and could she see it. I told her my cousin couldn't have possibly known as she has never seen it erect. I asked her when she had ever seen it wanting her to tell the story from her point of view. She denied seeing it, and said she just saw it through my shorts so she could tell that way. I just smiled and said yes I do have a very big dick.
Indeed I know that most guys would envy my eight inch cock as all the girls I've talked to since say that they are lucky to get a guy with a six incher. So turns out most guys are exaggerating when they say even that. I've seen cocks bigger than mine in movies but these guys are one in a thousand.
And obviously it's a good looking dick as my cousin can attest.
