"This is experiment number V-3 on subject X-999," Villiers said, apparently for the benefit of the hidden microphone and cameras. "The penetration by an aristocratic, king-sized cock of the ass of a common woman of the streets. She has been used by so many men that only her ass is tight enough to provide any sensation."

Marcy squirmed lustfully. "Yes – yes," she panted. "I've been used by so many cocks that I'm loose as hell in front."

Dr. Villiers leaned down close and whispered in her ear. "I assure you, my dear, this is going to hurt and hurt badly. But deep down in your heart of hearts, you will love every excruciating minute of it."

"Yes – yes," Marcy breathed, "hurt me, hurt me!"

She felt the hardness of his tool against her delicate little rosebud, and a shiver of fear mixed with excitement shook her. It was almost as though she were a blushing bride about to be taken by her masterful husband for the first time.

The monstrous rod was trying to enter now, straining to force open the tight bud of her anus, shoving hard against the barrier to the unused asshole.

"Ha! It is too tight. We must spread you more," Dr. Villiers said, getting his legs between her thighs and forcing them so wide apart that Marcy was sure she would rip up the middle. She held her breath for as long as she could, and then cried out with the pain.

"What's the matter, little whore? Am I hurting you?"

Marcy nodded, unable to speak, and he twisted a hand in her blonde hair, and yanked her head around so she could look into his stormy eyes. "That is good. Pleasure-pain is the object of this experiment, and you are the perfect subject for it. Hurt you is what we want to do, and hurt you we shall, until you scream and sob with the pure lustful pleasure of it. Do you understand?"
