She got off him and stood above his face.  Then, all of a sudden, she quickly lowered her buttocks onto him.  John groaned as her crotch landed on his chin.  Caroline sat back and rested her bottom cheeks firmly over his mouth and nose.  She could hear his muffled cries as he protested and asked her to get off. What he was actually saying was, “I can’t breathe!  I can’t breathe!” She made herself comfortable and sat with her superb, round buttocks, pressed into his face.  She could feel the warmth of his breath blowing through her jeans and panties.  Sliding backwards slightly, she positioned her pussy over his lips and nostrils.  It amused her to think that his air supply was being filtered through her vagina.  John continued to protest and try to struggle, but Caroline sat firm and wouldn’t let him move an inch until she was ready.  When, finally, she lifted the cheeks of her bum, he gasped desperately for air.  She stood up and looked down upon her prey, crushed and breathless on the hard wooden floor.  “Get up,” she snapped.  “Up!  Now!” His arms and legs were weak and he was shaking.  He barely had the strength to lift himself up, but her continual demands goaded him into action.  He managed to stand, but tottered about like a staggering drunkard. In a state of extreme annoyance, she grabbed his collar and quickly lifted her knee into his groin.  Instantly he was felled.  His legs gave way completely and he crumbled into a heap on the floor.  Caroline had never kneed a man in the balls before and was surprised at how easily he had gone down.  John laid on the floor, barely conscious, his hands desperately gripping his battered balls.  His head was spinning and he could only see blurred objects about him.  Then there was darkness.  The next thing John knew, his eyes slowly opened and he could feel Caroline fiddling with his testicles. Her fiddling felt fine at first, but then he could feel a sharp, stabbing pain.  Then he felt another, then another, and another.  It seemed as though she was sticking pins into his scrotum.
