Marcy nodded again, and then felt the head of his iron rod pushing brutally into the tight passageway. It hurt! Oh God, it hurt! Red and black flashes of pure agony stabbed through her, and were followed by alternate waves of the most incredible sensual delight she had ever known.

She screamed silently as the knobby head, having breached the entrance of her anus, was halted by the powerful sphincter muscle.

"Such a tight little ass," Dr. Villiers said. "But you must relax this constricting band so I can probe its pink and brown depths with my hot prick."

"I'm trying – oh God, I'm trying!" Marcy gasped, pounding her fists on the bed. "Don't take it out – please – oh, it hurts so goooood!"

Villiers slapped her sharply on the butt. "Shake your ass, whore! Welcome the prick that pins you to the bed like the slut you are!"

He reared upward and plunged down again. Marcy shrieked as she felt herself cracking and tearing to accommodate the huge weapon. She was sure that a bar of steel rammed up her back passage could be no more searing.

"Let me help you feel more joy," Dr. Villiers said, his arms going around her, his hands seeking her breasts. At first she thought he intended to caress them to take her mind off the knifing, burning rawness her asshole had become.

But she found that he had no intention of depriving her of a single instant of agony. His fingers closed on her tender tit flesh, squeezing and twisting cruelly. Marcy screamed and howled at the sea of flaming pain which washed over her.

"Be quiet, little whore!" he hissed in her ear. "Do you want everyone to know what delicious pain you are enduring?"

"I-I'm s-sorry," she wailed, "I c-c-can't help it!"

"Then I'll have to assist you," he said, and twisted his upper body sideways so he could scoop up her bra and panties from the floor. Jamming the wet scrap of nylon into her mouth, he tied the gag in place with her bra.
