"You're a sub-male if you know what I mean. You're a sub first and a man second. Get it, sub? It means your real value is that you're a sub. At least, that's how I see it. You have worth to me as a sub, not especially as a man and as far as I am concerned you're lower on the slut scale than a female sub, so you'll do what you're told, no matter what gender is involved. Isn't that right sub?"
"Yes Ma'am."
She was admonishing her tool for being reluctant to accept her friend's cock in his ass a few hours earlier. Slow to obey, in fact. Not a tendency to be encouraged in a sub, she thought. Disobedience was the one character flaw she could not tolerate. Her disappointed friend had commented that he was accustomed to slaves that were more compliant. The sub had embarrassed her and she would make him pay. Correcting the behaviour would just be a bonus.
"Put your hands flat on the floor and spread your legs. Wider. Stay Fido! Ass up! Keep it up there until I say different. You don't need to know why or what's going to happen next."
"No Ma'am."
"What? What did you say? Did you just defy me slut?! Spread wider!"
"Sorry Ma'am! I was agreeing Ma'am."
The slut struggled to spread his legs even wider, his anxiety building.
"Shut up slut! I'll decide what you meant. Ass up!"
The sound of a riding crop cutting through the air registered in the slut's ears a split second before the resounding crack of leather on skin proclaimed the first of many welts. The sub whimpered but held his position.
"Keep your ass up! You deserve every stroke." The whistle and snap of the crop cracking across his bare ass echoed in the room until inflicting pain wasn't enough. She needed something more. He needed to be humbled. It was time for her favourite sport, sub riding.
Her fingers worked a blob of lube deep into his bottom dildo hole. She took a minute to make sure her sub's cock was slick with pre-cum and as stiff as possible. The whore grunted and oozed more natural lube like a dispensing machine.
It only took another minute to fit the strap-on to her hips. The head of the large cock dilated his asshole and the rest of the 10 inch cock slid easily into its sheath. The slut squealed like a pig.
"This could easily be a real cock if I wanted to have you fucked by a real man. What would you say if it was, ass-whore?"
"Thank you Ma'am! I am grateful to be used as an anal slut any time you wish Ma'am." She pulled the big cock out then rested its head expectantly against the sub's dilated hole.
"You better thank me for fucking you. You don't deserve a real cock yet. You're not even a man, you're a sub. So you're an 'it' from now on."
Her hand found the ball sack and pulled the sub's erection down within her grasp. She gripped it's boner tightly and eased the head of the strap-on back into the man-cunt.
"Remember fuck tool! You exist to serve me. What are you?"
"I am your bitch Ma'am, your ass slave, here to be used for your pleasure," it replied. "Thank you for using me Ma'am!"
She drove the full length of the big cock into her whore's hole. The sub grunted. "That's right bitch, make some noise! I want to hear my fuck pig squeal... NOW!"
The sub squealed like a hog being raped by a backwoods farmer. She slapped her whore's quivering buttocks until they were glowing pink.
"Fuck faster! You do the work now."
The sub scewered it's ass back and forth on the big cock and grunted continuously to please it's user. As the dominant used her sub, she saw splatters of pre-cum drooling onto her hardwood floor and made a mental note to make it lick the floor clean when she was finished.
"Can I please lick your pussy Ma'am? It has been so long since I have been allowed to please you that way," it grovelled.
"Shut up cock-whore. If I want to hear you beg I'll tell you. Right now I want to hear you grunt while I fuck your slut-ass." She slammed the full length of the thick latex dildo into the sub's hole again and again as she picked up the pace. The sub grunted on cue, still dripping pre-cum onto the floor from it's engorged fuck-stick.
Finally the sub felt the long cock vacate it's hole. She slapped the quivering ass one last time then walked away.
"Lick the floor clean then crawl back to your kennel and lock yourself in," she tossed over her shoulder. "Remember, no playing with my cock."
......
She kept the sub completely naked and locked in a four foot high cage when it wasn't being used. She wanted it to become accustomed to crawling.
The sub-slut heard her approaching footsteps and backed it's ass up against one end of the kennel; the end with the little trap door in the center. With its ass pressed tightly against the cage bars, the sub crouched on its knees and elbows, waiting for the routine to unfold.
She undid the clasp of the trap door and pulled the sub's genitals through the opening. With it's cock and balls hanging outside the kennel, the sub made grunting noises indicating it was ready for the next step.
She stroked and slapped the long appendage until it stiffened then gathered the balls in her hand and stretched four hair elastics around them, effectively isolating the sub's balls away from it's erection. She played with her creation for a few minutes until she was satisfied that the cock was rigid enough and the ball sack as tight as possible then she snapped a leather cock strap decorated with chrome rivets around it's genitals.
"What a whore," she thought as she worked another finger-full of lube into the sub's rear fuck hole. The insertion of a large black butt plug coaxed a loud grunt from her bitch. She laughed and slapped it's ass playfully before closing the access door. Standing beside the kennel she stuck her hand through the bars. The sub licked and sucked the excess lube from her fingers.
With it's back hole plugged, it's cock stiff and it's balls stretched, the sub waited patiently on all fours for her to open the cage. Finally she clipped a leash onto its collar and pulled the bitch out.
Adopting the submissive posture she had trained into it, the sub grovelled on it's elbows and knees at her feet and thanked it's owner for her attention.
