Rita sits on the slaves face in her black leather skirt. She sits on the Alexs nose and mouth very rigidly and prevents him from breathing. When the slave is wiggles she stand up to give poor boy some air. Rita sits on Alex in different poses, and the most comfy, is when she put her gams over the slaves figure and shoves his face with her full weight 49kg 108lbs. In this pose she dont want to stir. So Alex should take a really big breath and hold it, until Rita thinks thats enough. For how much time will slave holds his breath? Also, you can watch some scenes from the slaves point of view PoV.
