As John did what she commanded, he realised that she was going to use his mouth as her ashtray.  The hot ash dropped onto his tongue and she ordered him to eat it.  It was a very distasteful task, but John was a beaten man and he had no more fight left in him. Caroline pressed the burning cigarette into his flesh and it sizzled.  John screamed blue murder and she had to warn him to keep his noise down, for fear of upsetting the neighbours.  Then, the final agony for him, was when she actually stubbed out the cigarette on his back.
He fought with himself not to scream out, however much he wanted to.  But he could not control himself and he let out a shrill cry. Before he knew it, he felt a gag being forced between his lips and into his mouth. 
The gag pressed down on his tongue and she secured it tightly so that he was unable to make any sound.  She sat on his back and rode him headlong around the room as if he was a horse.
She stroked his thinning hair and cooed, “There, that will stop the little baby from crying.  Such a good little boy.”  Then, after John had finished crying, she unbuckled the gag and asked him, “Is he a hungry boy?  Does he want some nice cake?”

A piece of cake dropped at his feet and she ordered him to eat it.  Just as he went to pick it up in his mouth, she pressed her boot down on it and crushed it.  She stamped on it with her heel and flicked her toecap up into his mouth.  She played a little game with him, moving her foot from side to side, tempting him to grab the cake between his lips. 
As John bolted forwards to get the cake, her boot slammed down on the back of his neck, pinning him to the floor.  His nose was squashed into the cake and she made sure that it went all over his face.  By now, she was giggling uncontrollably.  When she was satisfied that he had been humiliated enough, she ordered him to lie on his back, whereupon she stuffed the cake into his fat mouth and rammed it in.
Caroline helped him eat by forcing it into his mouth with her boot.  It amused her greatly to see him eating food from her soles and heels.  To her, it was the perfect message, that he was only fit to eat the dirt from under her feet.  And as he chomped away on the cake, she watched, feeling happy that she had explored her sadistic fantasy.
