Sitting On His Face While I Ruin His Orgasm

Description: My slave and i both get to enjoy ourselves tonight, but i think i will be enjoying it more than he will. first, i'm going to sit on his face while i vibrate myself to multiple orgasms. i love smothering him while i writhe and gasp in ecstasy, knowing his breathing is controlled by my ass.  then, if he's done a good job of being my chair, i will give him a handjob. whether he gets a pleasurable orgasm or a ruined orgasm will be up to me, obviously. what can i say, i love ruining his orgasm, so just as he's about to cum, i pull my hand away and laugh as his pathetic cum load dribbles out onto his belly!
