A Rough Night
by ploxiet

It's a long weekend and our cousins are staying over at our house. To accommodate them I have to share a bed with my step-sister, Jess. Now, under any other circumstances I probably wouldn't have minded sleeping in the same bed as her, but, due to the large amounts of food she ate today, I have a feeling it's going to be a very long night.
By the time I come upstairs to bed, she is already sleeping. I climb in and I'm suddenly hit with a strong smell of egg and vegetables, the warmth of her farts encases my body. Jess is sleeping topless with only a skimpy piece of underwear on, lightly farting every 10 minutes or so.

As I'm lying there trying to sleep whilst avoiding the worst of the smell, a low rumbling fat erupts from Jess and I jump in surprise. I accidently hit Jess with my leg and she jerks awake. "Brad!" She yells. "How dare you wake me up, I was having the best dream!" while turning on the light. Jess notices the strained face I'm pulling due to the smell in the bed and a wide mischievous grin appears on her face.

Before I have time to do anything, Jess rolls over and lays on me, face to face. I'm pinned down to the bed and she uses her breasts to smother me, a faint "mmmppphhh" is all that I can muster in protest. She holds me like this for a whole minute and finally gets off, leaving me gasping for breath. Jess uses this time to pull out some rope from the bedside table. She uses this to tie me up. So there I was, lying down on the bed in my boxers with my hands and feet tied with rope, hardly able to move.

Jess stands over me and turns around so her ass is facing me. I look up at it, slightly aroused, which is quickly forgotten as she releases a deep "BRRRRMMMMPPPP" and lowers her ass down onto my face. I get an overwhelming whiff of her underwear which she has probably been farting in all day and it causes me to cough, I hear a small giggle from above me. Jess lets out a couple of quick, small farts that smell like egg and cheese. I try to hold my breath but she notices and pushes down on my stomach. All the air rushes out of my lounges and as I breathe in, a hot wind that is her 5 second SBD passes through the fabric of her underwear and onto my face which I am forced to take in directly to my nose. Jess remains firmly seated upon my face and I start to feel light headed, but before I pass out she rises off my face and allows me some much needed fresh air, even if it is tainted with her farts.

Jess removes her underwear and sits back down onto my face completely naked. My nose is pushed straight into her asshole which is caked with faeces and a small fart welcomes me. The smell is indescribable, my body jerks and I start to gag. Jess grabs the back of my head and holds me in place with my nose basically inside her asshole. As I start to feel unconsciousness come my way again, I notice that jess doesn't move and I feel a wet substance on my nose as the blackness takes me.

Jess drags my body into the ensuite and places me next to the toilet. She sits upon her throne and takes a long and fart powered dump. She leaves it unflushed with the lid open and vacates the room to get back to sleep. I wake up in the morning and my senses are once again invaded with the smell of Jess's last meal. I glance over to see her soaking in the bath laughing. "Oh no…" I think to myself.
