You were sitting on the couch, mom in her room. The door to her room opens and mom tells you to come in.

"Okay, mom." You don't have a clue what she wants. You go into her room.

"Sweetie lay down on the bed." You do as your told. Mom walks over to the bed. She stands in front of the bed. She starts to slide down her shorts. Revealing her lacy panties, not giving her much coverage as they are completely see-through.

"What are you doing mom?"

"Honey, do you remember the potato salad and tacos we had for lunch?" She asks you.

"Yes, you ate a lot. Even though it always makes you very gassy." You answer. She walks over to the side of the bed and climbs on top. Crawling over to you, she faces her butt toward you. "I don't want your dad or your brother to have to smell my gas. So I'm going to empty out beforehand."

"What do you mean mom?" You are still utterly confused. She grabs the back of your head with her hand, and slowly lowers her ass on to your face. Once sitting on your face she squirms around a little bit, pushing you deeper into her crack until you feel her hole touch your nose.

"Mom, what if you have to fart? It stinks down here already!" You say.

"Sorry hun, I haven't been washing down there, as for your question if I have to fart, you are going to smell it, very deeply. I should hear you sniffing! If you don't follow my orders I will punish you. Let's begin." She explains.

PPPPBBBLLLTTT

Mom's face is pure euphoria. The smell of her fart forces is way down your nose. It smells of rotten meat, eggs, and vegetables.

"I don't hear you sniffing!" As she says this, you are forced to take a deep breath or you will suffocate. Your eyes start to water and you cough violently.

"That one was hot coming out so it must smell. I have to take a dump soon, it always makes my farts smell extra bad. That was a small one too." She says obviously taking pleasure in your suffering.

"Mom went are you doing this!? It stinks! Please let me go!" You beg.

"Your not going anywhere!" She yells at you.

BBBBBBBBBBBLLLLLLLLLLLTTTTTTTTFFFFFFFSSSSSHHHHHHPPPPPPFFFFFFFTTTTT

"O MY GOD! Fuck, that feels good. Probably doesn't feel good for you though." You are in pain. You are also starting to go unconscious. She feels your struggling weaken. She does one last fart to finish you off, for now. She had more plans of pleasure for herself, but she decided to do them later.

PPFFFFFFFFFFFTTTTTTTBBBBBLLLLTTTSSHH

You go unconscious knowing she's not done with you.
