Between the Balustrade Posts

A house we bought some time ago had some stairs with a balustrade consisting of wooden posts. The spacing of the posts got me thinking about whether my cock would fit between them. One day when my wife was out I tried to insert my cock between the posts, and it was a perfect fit. It was just tight enough so that as I thrusted, my foreskin would be held back by the posts and my cockhead poked through the other side of the balustrade. I bet you can imagine how I thrusted my cock in and out of that balustrade! It was lovely! I fucked the balustrade for 15-20 minutes and blew a huge, spurting load onto the stairs below. I cleaned up just in time before my wife came home.
