My son Johnny came home tipsy again! And he busted in right in the middle of mommy's special relaxing time! The hitachi was working it's magic and I was just about to cum! This young man is such a handful! And then he pulled his dick out and got into my bed... out cold. Luckily, I thought, he wouldn't remember what happened. And that got me thinking... maybe I could have a little fun and get away with it. I've always been curious about my son's cock, and how big it is when it gets hard, especially since he got semi-erect last week when I gave him a shower. Well... it's big. Really big. And he cums A LOT! I'm a very proud mother :)
