Beautiful Mistress Mercy is roughing her slave up on the bed. To start she is sitting on his chest and slapping his face with her sock covered feet. She places her soles flat on his face and lifts her body up so a good amount of her weight is now on her legs and feet and on his head. His face is getting crushed real nicely. She slides forward and wraps her legs around his neck pulling his head up into her crotch so she can scissor him. She rolls onto her side with his neck between her thighs and squeezes. She reaches and pulls on his nipples before shifting so her ass is right in his face and lets out an absolute monster of a fart causing the slave to say "Oh my gawd." That's a blast that fills the room. "That one just slipped right out" she says and comments how nice it smells.She scissors him again and this time his nose is right in her pussy but not for long as she gets up, pushes him on his back and sits on his face sidesaddle. She then turns his head to the side so his nose is right by her ass crack and again releases a timely fart. "I'm just so gassy today" she says. Now she turns into a forward position and this times sits on his head so his mouth and nose are covered. She farts again so lifts up to insure he smells it. She then turns into a reverse position and says she wants to see if he can hold his breath for 5 minutes causing him to gasp. She tells him to take a deep breath then sits full weight on his face. A minute passes and suddenly the slave starts to kick frantically. "You still have another 4 minutes to go" she says.
