Seat pad has to lift me to breathe

Description: For this facesitting session i came up with a mean plan again ... the slave is going to be allowed to breathe as much as he wants - he only has to lift me! the longer i keep sitting on his face, the less oxygen he has to work with and the less energy his muscles have. and obviously, the position i take has a great impact on his chance of success as well :-d this loser already begs for mercy after a short time - but he really shouldn't hope for mercy! this game is way too much fun for me to stop already!
