Madame Marissa - I'm going to sit on your face!

I bet you'd love to be my human seatpad, wouldn't you? Well, you will surely never experience this in real life - but at least now you can dream about it! Look at my tasty ass in these skin-tight jeans - as it slowly descends and then stays on your face - smothering you underneath. Will I get up often enough for you to survive? Do you think I care?!
