Im hopping onto the slaves belly from the stool. Hes lounging on the ground and serves me as a trampoline. Again and again I leap onto him with my naked feet - his soft belly is just perfect for that! And its so much fun to jump on him! Even better when I can enjoy the trampoline slaves humiliation as I work out on him! I jump on his body and he has to say DONG! This slave truly internalized his task and serves me unconditionally! Thats how I like it!
