He thought he Loved Face Sitting

Sure it's fun when a Mistress sits on your face, bare bottom, or wearing a silky pair of panties, every slave loves that.  To keep the subs off balance though the ladies sometime mix it up and today for the Queen of Mean, Lady Bellatrix, that means the slaves head will be on the infamous rock hard green bench, she'll be wearing leather pants and to add some fun to it her gassy state will insure that while he struggles to breathe the air he does suck in is rancid.  

He likely has changed his mind on how much he likes face sitting but Bellatrix reminds him that he might hate it now the memories will be worth their weight in gold.  Enjoy this scene as Lady Bellatrix subjects her slave to a face sitting session that will linger long after it's done.
