She smothers you

She takes your hand and drags you away from the tables to a grass area. "Lay down here" she says. You do as asked and lay down on the grass, face up. "So..has the timer started?" you being to ask, but Mary shushes you. "You belong to me, and my property doesn't talk. Open your mouth" she commands. You reluctantly open wide. She steps over you, one heeled boot on either side of your face, giving you a perfect view up her long skirt to see...her bare pussy. She had no underwear on. She turned around, so she was looking away from you, and slowly began her descent. Her fat wobbling ass cheeks spread as they lowered themselves onto your face.

"Good boy, now get licking, or I'll never let you go" She says. Just as you attempt to protest her ass pushes down on your open mouth, smothering you. You try to breath, but are overwhelmed by the musk of her ass. You splutter and try to throw her off. "Bad boy!"
She reaches out a hand and grasps you balls, squeezing. You immediately stop fighting.
"Get that tongue to work"
She begins to gyrate, grinding her plump ass into your face. You stick your tongue and, and begin to lick at her hole, her hand still holding your balls.
"Deeper" she commands
You obey, forcing your tongue inside her. You're starting to feel lightheaded, maybe if you please her she will let you go. You've lost track of time, but you've definitely been under her for more than three minutes.
"That's right, make out with my ass"
As your vision begins to blur and fade, you passionately kiss her ass. In this state of half consciousness, you actually start to enjoy it, and then everything fades to black.
