My slave is trying to get stronger to go on a date with a girl, but I laugh at him and remind him that he is nothing more than a seat to absorb farts. He could never be loved by a girl. I easily push him over and sit full weight on his face and call up my boyfriend because I'm horny and I can get all the sex I want. My slave struggles to breathe but every time he can catch his breath his lungs are just filled up with my gas. My phone conversation gets really steamy as I start pleasuring myself, spreading my legs so you can see my slave's face trapped in my asshole and my wet pussy just out of reach. He gets destroyed beneath more toxic gas as my sex talk gets hotter and hotter. I discuss him coming over later and we can both fuck on top of my human seat, then he can clean the cum off of both of our genitals after. I'll even let my boyfriend bring another guy so my slave can have more cum to clean. The chastity slave will never get to experience sex of any kind except as a cleanup tool. Eventually I get off the phone with him, then I bounce and slam my ass down on the weak slave's body until he is nearly crying. He doesn't want to be subjected to this level of torment, but there's no escape from this fate.
