"Not good enough, you dumb cow. Try again," said the young mistress sternly.
Kathleen Ballard took a moment to compose herself. She was an English professor. She should be able to string together a few coherent sentences and come up with a compelling and convincing argument that would satisfy her new mistress.
Professor Ballard was a 44 year-old divorcee who had discovered lesbianism relatively late in life. She liked her girls young. She had met two of her students at a faculty reception earlier in the evening and had been lured back to their off-campus apartment. After a brief period of flirtation and some intense and honest introspection, she had agreed to become the slave of Jennifer Parker, a 21 year-old senior.
Presently, the professor was naked and collared and kneeling between the legs of her new mistress. Her fellow slave, Kendra Wilson, a junior at the university, also collared and naked, knelt beside her. Their beautiful brunette mistress had also disrobed. She was sitting patiently on her living room couch, wearing a large strap-on dildo.
Professor Ballard had spent the last fifteen minutes on her knees begging the petit brunette to fuck her up the ass.
Earlier in the evening, the professor had been cunt-whipped for the first time by her young mistress as part of her initiation in to slavery. To finalize the deal, Professor Ballard had to convince her new owner to take her ass.
Jennifer was playing hard-to-get. She was obviously enjoying the older woman's discomfiture.
To give herself a little more time to think, the professor leaned forward and took the large black dildo in to her mouth again. She began to bob her head up and down, taking in as much she could with each plunge. The dildo was at least eight inches long and seemed almost as thick as a can of soda. Professor Ballard gagged several times as she tested the limits of her gullet. She had no idea how she was going to fit this beast in to her ass, but she would cross that bridge when she came to it. First, she had to convince her mistress to fuck her.
After a few seconds, the professor expelled the dildo from her mouth and took a deep breath. She looked up at her mistress as she spoke.
"Please, mistress, I am begging you. Use this worthless whore's ass for your amusement. I'm a virgin back there, mistress. Nobody has ever fucked my ass. Please take my cherry. I'm offering it to you as tribute. Mark me as yours, ma'am. I promise I'll do whatever you say if you take me. Use me however you want. I'll be a good whore for you."
The professor continued to stare in to the eyes of her new mistress. She hoped she wasn't pouring it on too thick.
The pretty brunette mistress paused reflectively for a long moment. She touched the tip of her right index finger to her chin.
"Hmm. Well, okay," said the young brunette brightly. "If you insist, Professor Ballard, I will gladly fuck you up the ass. Get on all fours please."
Professor Ballard immediately pivoted on her knees and got on all fours with her ass facing her mistress.
"Kendra, wet her for me, please."
The pretty blond slave immediately crawled over to the middle-aged woman and pulled her ass cheeks apart with both hands. She then began running her tongue up and down the older slave's crack, slathering as much saliva as she could on the puckered ring of muscle.
The young mistress stood, then got down on her knees behind the professor. The large strap-on bobbed lewdly before her as she adjusted herself and got in to position. Kendra was still laving the professor's asshole noisily, making loud slurping sounds. The new slave began to moan.
"Let's see what we have here," said the young mistress.
She held out her right index finger to Kendra. The blond slave immediately let go of the professor's ass and crawled over to take the digit in her mouth, coating it with her saliva.
After a moment, Jennifer withdrew her finger from the Kendra's mouth.
"Hold her open for me," said the pretty brunette evenly.
The blonde slave knelt to the right of the professor and drew apart the older slave's shapely ass cheeks.
Without preamble, Jennifer plunged the finger in to the professor's asshole to the hilt.
Professor Ballard grunted, but did not move.
"You have a very pretty asshole, Professor," said the dark haired beauty as she began to saw her finger in and out of the tight passage.
"Thank you, mistress," breathed the professor.
"Nice and tight for an old cow like you."
"Thank you ma'am."
Jennifer worked another finger in to her ass. The older slave began to squirm slightly.
The young mistress smacked the professor smartly on the ass with her left hand.
"Be still, slut. I need to widen you."
The professor immediately stopped squirming and remained perfectly still. Her pussy whipping was still fresh in her mind. She understood the importance of obedience.
"Kendra, I'm going to need actual lube. It wouldn't be safe to dry-fuck a virgin ass. Please run and get the large bottle, will you?" she commanded breezily.
The blond slave immediately jumped to her feet and scampered out of the room. In a moment she was back with a large jug of clear lubricant. She handed the bottle to her owner.
"Thank you Kendra. Now, please lie down and get ready to feed her your pussy. I will let you have her tongue when I'm all the way in."
The pretty blond slave circled to the front of the professor and sat down nimbly. She leaned back on her hands and spread her legs wide apart, scootching herself forward slightly so her pussy was only inches from Professor Ballard's face.
"Professor Ballard, please pull your cheeks apart for me, dear. Offer me your hole," she said.
The older slave lowered her forehead to the ground to help balance herself, then dutifully reached back with both hands and spread herself for her new owner.
The petite brunette drizzled some lube directly on to the two fingers she had already stuffed up the professor's ass. She could feel the muscular tissue softening and beginning to yield to her ministrations as she continued to gradually apply more pressure against the edges of her canal with her two fingers.
In a moment, the third finger was in.
The mistress began rotating and twisting the three fingers to the right and left as she plunged them in and out of the professor's ass. She could clearly hear the older woman panting loudly.
In a moment, a fourth finger was in.
She fucked the professor's ass with all four fingers for a few minutes until she was satisfied that she had dilated the passage enough to accept her cock. Finally, she sank her fingers in to the hilt and paused.
She was ready.
"It's time, Professor. Time for me to make you my slave."
"Yes, ma'am. Oh, God, please."
"Do you want to be owned by me, Professor Ballard?" asked the young mistress, casually.
"Yes, mistress."
"Do you want to be my lezzie whore?"
"Yes, ma'am. I'm begging you."
"Ask me nicely to fuck your ass, Professor."
"Please fuck me mistress. Please use your whore's ass."
"Very well, slut," said the blue eyed mistress as she withdrew her fingers from the older woman's ass.
The petit brunette leaned forward across the professor's body, then reached out and casually held her hand in front of her new slave's face.
"Clean these for me, please, cunt."
Professor Ballard turned her head to the right and engulfed the four wet fingers in to her mouth. She sucked and licked them clean, moaning softly as she did so.
After a moment, Jennifer withdrew her hand from the slave's mouth and closed it around the shaft of the large strap-on dildo.
"Here it comes, Professor," said the dark haired mistress as she carefully placed the bulbous head of the large phallus against the older woman's virgin hole.
Jennifer advanced the dildo slowly and methodically. She watched as the ring of muscle stretched tightly around the large head.
The professor was breathing heavily and grunting. She began to push back against the dildo.
"Bear down, Professor," said the mistress curtly.
The effect was instantaneous. Jennifer felt a moment of increased resistance, then a subtle pop as the large head cleared the professor's tight sphincter.
"Oh, God!" groaned the new slave.
The young mistress steadied herself on her knees behind the professor. Then, she reached out with both hands and grabbed the older woman firmly by the hips.
"Feel free to scream, Professor Ballard, but try not to squirm around too much. I don't want to tear you, " she said matter-of-factly.
Then she thrust her hips forward and slammed the dildo deep in to the older slave's ass with all her might.
Professor Ballard screamed. She felt like she was being torn apart. The pain was majestic and transcendent. She almost blacked out. She felt hot tears come to her eyes.
The slave began to whimper piteously, but she did not move. She stayed stock-still as instructed by her owner.
Jennifer paused with the dildo inserted to the hilt in the professor's ass. She smacked her new slave's ass hard with the flat of her right hand.
"Settle down, cunt. The worst part is over. You did well. You may now eat Kendra's pussy. Do a good job, please."
Kendra shifted herself forward a few inches as Professor Ballard lowered her face to the blond slave's pussy and began to lick.
