Big Fat Mistress wearing only a bikini is having her way with a female slave. She has bought a new face sitting seat off ebay and can't wait to try it out. She calls over the slave and orders her to sit on the floor. She puts the new face sitting seat on her face and tries it out. The slave can't move and her full body weight is on top of her face. It is impossible for her to breathe but this also makes it hard for her to scream.
