I start by teasing the slave with my sweaty nylon feet - fresh out of my office heels ... but he's not going to smell them today ... I take off my nylon socks and stuff them into his mouth, then immediately start to smother him! I press my hands firmly on his mouth and nose and prevent him from breathing - while he gets to suck the disgusting foot sweat taste out of my nylons! I alternate between smothering him with my hands and my feet - but it's really easy to smother this wimp anyway! I'll make sure that he remembers this humiliating smother session for a long time!
