Great sounding. What size can you go up to? I can get a 14 mm diameter rod in *just*. It's tight but it will go. For length my longest is 250 mm and I can get that all the way down.
The key to sounding is slow and steady. It takes time to move up to larger things. I have been sounding for years and I am only up to a 14 mm diameter rod. It's like exercise, you build up slowly.
What an awesome closeup of your big, fat cock taking a really good deep sounding. I love the ease that Sharpie marker slipped fully inside your cum hole, I have tried but never succeeded like that. your happy ending, nice thick torrent of creamy semen. Mmmmmmmmm mission accomplished.
