I fantasize about being a sexy, exotic, powerful woman's sex slave. She brings me to a party where I sit at her feet while she talks with other powerful people. A strong man and her get into a lengthy conversation that the man has to interrupt because he needs to take a piss. My mistress offers him the use of her slave which the man accepts. While they continue their chat, the man stands, takes out his cock, takes my head in his hands and forces his large semi-stiff cock down my throat til it's buried. After a minute I feel warm liquid flowing down my throat as the man relieves himself. He pisses for a long time. when he's done I clean him with my mouth and he puts his cock away and sits back down. The rest of the night I know that every beverage I see the man drink is going to be pissed down my throat later on.
