Yes

You take your hand and spank her as hard as you can. And again, and again, the sound of the slaps echoing through the large room, though Martha herself makes no sound.

“You’re not doing it right,” she finally says, turning around, and grabs hold of your hand. “You said you’d do it the way I want, and I don’t want you to spank me with your hand.” She smiles at you, as she squeezes your hand, and twists your wrist painfully, finally forcing you to fall to the ground. “I want you to spank me with your face.”

Before you can say anything, her ass smashes down on your face repeatedly. You yell and scream, it feels like your nose might be broken, but still it carries on, just as you agreed to, and it does indeed hurt really really bad. It all blurs into one, as she continues the pounding, until finally she’s satisfied and those soft fleshy pillows come down one final time, smothering you, sending you to a welcome oblivion.
