I put my slave in his little fart box, restrained his arms, duct taped his mouth, blindfolded him and tied his balls tight to the box. After that plant his face in my smelly skirt for 15 minutes, shooting so many stinky farts right up his nose. I don't move much as his nose is perfectly pressed up against my asshole, so every breath is nothing but me, especially since my skirt is holding all these farts in the fabric. He struggles with some of them but sniffs obediently everytime I let one go. It ends with me sitting sideways on the box as I watch his teased cock bounce up and down through a rough ruined orgasm.
