Extremeass10, the master of bizarre and extreme insertions, is back with a new challenge. In 'One of my most extreme insertion!', he introduces us to the world of tennis ball gaping. Watch in awe as he slowly inserts the spherical object into his already gaping ass. The pressure mounts, the ball disappears, and what's left is a sight that'll make your eyes water and your jaw drop. This is extreme fisting taken to a whole new level.
