She sits on your face and makes you pleasure her from underneath

She is aroused now, and she instinctively throws you down on the sofa and stands above you.

"I need you down here now, and I won't let you say no" she says, pointing at her ass.

While you are stull stunned from the suggestion, she puts her ass down on your face - you are trapped under her weight now, and **** to worship her ass, or die struggling.

She sits on your face and makes you pleasure her by licking her from underneath.

Her immense weight rests relaxed on your face, exerting incredible **** on you.

An hour goes by, with a helpless man under a thoroughly excited and aroused big woman. You don't know how much more of this you can take....
