Pumping Air into my Dick until my Belly bulges

Inflating my bladder with air has become one of my favorite things to do. I love how it can compress and I can squeeze and push my belly while the pressure increases. And you know I'll never stop until I feel like I'll pop! Sorry about the resolution. Had to get my cam repaired but couldn't wait until I get it back so I had to record with my endoscope :D
