(Custom) As you are probably aware, smashing my slave under full weight is something I do often. I like to do it in many ways as well. But today, I am here to conduct some important research. I want my slave to give me feedback on the pain levels of various forms of sitting, compressing, etc. I need to know what hurts the most! You know... for science! In this video, I sit on my knees on the slave's back, his head, his neck, and chest, taking notes and asking the slave how much they hurt on a scale of 1-10. Since I put a gag on my test subject, it's hard to understand what he says, so I have to keep digging my knees in until I can hear what he says. My 100kg make the slave cry and tremble under the weight. I sit on his head which ends up bruising his face from pressing it into the floor. Finally, I give the slave my dreaded boston crab. After running numerous tests on the slave, I find out which one hurts the most, then give it to him harder than ever in the finale! Buy the clip to see what happens!
