Today I decided that my slave was ready for the next deep feet challenge. This time his objective was to reach the 15 cm (5.9 inches) mark on my cute long feet. He knew that I could just keep pushing my feet deep untill he reached that objective.
After a while, he was complaining and whining, he didn't even want to open his mouth anymore at some point, but I didn't care, the objective had to be reached.
After a lot of effort, me using all my weight on one foot in his throat and some throwing up, he could barely touch that mark! I was proud of him, so I made him cum and made him lick his cum from my foot too.
Next objective will be to reach the heel!
