This time I wanted to know how deep my slave can take my feet, so I marked them to see his improvements. I also used all my weight on one foot to push it down as much as I can and this time he almost take half of my 24cm feet. In the end he even threw up a bit because he couldn't handle them anymore, but I can see improvements :3

He deserved to cum this time so I touched him a bit at the end, till he came with a foot in his mouth muffling his moanings.
