Your stepsis is the big pest of the high school who dresses ultra sexy and flirtatious and who makes fun of you constantly. She catches you checking her out when you come home from school, and will blackmail you so that she doesn't tell your family.
You will have to satisfy all these humiliating desires of sadistic pest. You will have to do things with dog shit.
She will pick up droppings from the freshest to the moldiest in the garden. Then she will pee in the garden to spray you and humiliate you.
First, she will make you sniff them, lick them and suck them... You will not be allowed to flinch otherwise she will remind you what awaits you if you refuse. She will film with her phone to show her friends, it makes her laugh to see you do that!
Then you will have to insert the turds in your slutty ass, to come and shit it afterwards. You will do it several times. Caviar belonging to you will come out at the same time and you will come and lick it.
You will have to cover yourself with the shit, then you will fill your ass again with dog shit to shit it afterwards, several times. Without forgetting to come and bring the moldy turds to your mouth.
You will fill your mouth with very moldy caviar and will start to destroy your ass with a huge dildo, and this in several positions.
You will fuck your ass with the shit collected in the garden (I will also fuck my pussy in the video with it). You will shit the turds once again (I will shit some through the pussy too, in addition to the ass), before continuing to destroy your ass and offer me beautiful prolapses...

Are my experimentations with femdom getting out of hand? It's getting so extreme, poor slave! Well, I'm just getting started. Wink I enjoy it so much and my obedient slave submits to my will like the good dog he is.
I get off on suffocating men with my smells, from farts, poop, feet, sweat, breath... I didn't shower for days and I'm so horny, masturbating on the couch. I call my slave from his pen and order him to set with me. I make him smell and lick my sweaty armpits while I keep rubbing my lustful pussy. I put my shoes in his face and make him lick my feet. I stick my dirty toes up his nose. I unleash many nasty heavy loud farts in hise face.
I make him sit on his knees. I bend over and make him dig his nose in my ass. I unleash more nasty loud farts. Then wet farts, then sharts, then a HUGE load of thick creamy nasty soft shit fills my tight jeans. I keep pulling his head in and my mass of nasty creamy smelly poop is shaping around his nose. I grind my extremely dirty pants in his face and he can barely handle it.
I stick my hands down my pants and scoop up a thick plaque of my smelly poop. I make him smell it and then smear it in his face, in his mouth. Wow this is fun, I wanna do it again! So I do! This time I smear my shit directly up his nostrils, filling him up. The whole situation turns me on so much that I command him to lay down so I can ride his face in my dirty jeans. I enjoy a delicious dirty orgasm. I take off my nasty pants and smother him with it. He's unable to breathe cause of all of my shit heavily caked on his face and in his mouth. Good boy!
